Thanks to my friend Rajeshh who notified me on this feature.

DEMONSTRATION

1)    Create a tablespace TS_AUTO
create tablespace ts_auto datafile ‘+AUTO_DATA’ size 500m;

2)    Crate a database user called AUTO_USER with default tablespace as TS_AUTO
create user auto_user identified by auto_user default tablespace ts_auto temporary tablespace temp quota unlimited on ts_auto;

3)    Grant required privileges to the user created in previous step
grant connect,resource to auto_user;

4)    Create a database session as auto_user
conn auto_user/auto_user

5)    Create a table called T_TEST
create table t_test(t_dt date);

6)Insert some values in to T_TEST
insert into  t_test values (sysdate);
/
/
/
commit;

7)Check the data which we had inserted in previous step
select * from auto_user.t_test;
8)Using RMAN backup the database and arvhivelogs

rman target /

backup database plus archivelog;

9)Get the latest log sequence number

SQL> select sequence#,thread# from  v$log;

SEQUENCE#    THREAD#
———- ———-
720          1
718          1
719          1

9) Create a small parameter file

cat /u01/dba/temp/auto_tsptir_check/initEEeE.ora

db_name=TESTDB1
db_unique_name=EEeE_tspitr_TESTDB1
compatible=11.2.0.0.0
db_block_size=8192
db_files=200
sga_target=1G
processes=20
db_create_file_dest=/u01/dba/temp/auto_tsptir_check
log_archive_dest_1=’location=/u01/dba/temp/auto_tsptir_check’

**note Automated TSPITR creates its own parameter file but the SGA_TARGET in that is only 200m which will cause the whole procedure to fail due to insufficient memory, That is the reason we created our own parameter file and will pass the same during ATSPIR

RMAN> set auxiliary INSTANCE parameter file to “/u01/dba/temp/auto_tsptir_check/initEEeE.ora”;

executing command: SET auxiliary parameter file
using target database control file instead of recovery catalog

10) Perform Automated Tablespace point in time recovery.
RMAN> RECOVER TABLESPACE ts_auto      UNTIL LOGSEQ 720 THREAD 1       AUXILIARY DESTINATION ‘/u01/dba/temp/auto_tsptir_check’;

**AUXILIARY DESTINATION is where rman stores all the database related files for the auxiliary instance.
11) Change the status of the tablespace to online

alter tablespace ts_auto online;

library cache tuning – A Real Case Study.

Scenario :

Users started complaining about very poor application performance, hung and incomplete transactions. Some severity one ticket for immediate action.

Environment :

Oracle 10g (10.2.0.4) Two node RAC, About 15 different Java and .net legacy applications.
Highly transactional.

11 Gig Shared pool
16 Gig DB cache

Availability : 24*7, Outage unacceptable to business

I made some observations, thought it would be a nice idea to share them with you all.

Here are the citation from AWR report(1 hr.) during the problem period.

Snap Id Snap Time Sessions Cursors/Session
Begin Snap: 39718 07-Jun-11 05:00:13 438 66.3
End Snap: 39719 07-Jun-11 06:00:19 651 64.4
Elapsed:   60.09 (mins)
DB Time:   490.75 (mins)

• Very poor response time can be visible from the differences between db time and elapsed time – No wonder why users were complaining.

Load Profile :

Redo size: 698,307.96 9,249.30
Logical reads: 187,227.45 2,479.88
Block changes: 4,078.58 54.02
Physical reads: 29.63 0.39
Physical writes: 79.30 1.05
User calls: 2,638.29 34.94
Parses: 1200.23 5.81
Hard parses: 52.84 0.70
Sorts: 230.95 3.06
Logons: 0.91 0.01
Executes: 601.64 7.97
Transactions: 75.50

• Parse count is just half of user calls, so every two user call there is a parse request.Dammn bad, this going to be a huge CPU consumer.

• Hard parses per second is 52.84, if I said very bad for parse count, I should say very very very bad for hard parse – this is very much resource intensive. Unacceptable !!

Instance Efficiency :

Buffer Nowait %: 100.00 Redo NoWait %: 100.00
Buffer Hit %: 99.99 In-memory Sort %: 100.00
Library Hit %: 91.75 Soft Parse %: 87.95
Execute to Parse %: 27.13 Latch Hit %: 99.97
Parse CPU to Parse Elapsd %: 2.17 % Non-Parse CPU: 97.35

• Low execute to parse ratio denotes CPU is significantly busy in parsing. Soft Parse% showing, most of the parse are soft parses. It means we should focus on soft parsing activity.

• Parse CPU to Parse Elapsed % is quite low, which indicate  some bottleneck is there related to parsing. It could be a side-effect of huge parsing pressure. Like CPU cycles are not available.

• Library Hit % is very poor, it should be atleast above 95% .
  

Top 5 Timed Events :

latch: library cache 6,470 16,152 2,496 54.9 Concurrency
CPU time   11,675   39.7
log file sync 193,236 1,109 6 3.8 Commit
log file parallel write 224,479 795 4 2.7 System I/O
db file sequential read 38,110 386 10 1.3 User I/O

• High wait on latch: library cache . So very clear that slow performance is due to the contention in Library cache.

• Also looked at SQL ordered by Parse Calls and SQL ordered by Version Count. That pin point the issue at library chache.
  

Whats next ? ?

Above observations indicate that there is some serious problem to share the sqls. It could be a result of bad application code wihout bind variables . Each calls are going for a parse – either soft or hard and no caching. The obvious advantage to caching cursors by session is reduced parse times, which can leads to faster overall execution times.

Caching Caching .. Lets look at the Oracle caching parameters now. The value was

cursor_sharing= similar

open_cursors= 3000

session_cached_cursors= 100

Two things I played around was cursor_sharing and session_cached_cursors. I can ignore open_cursors for time being as it is already high for my environment.

I have chosen to use SESSION_CACHED_CURSORS to help out in this scenario as an application that is continually closing and reopening cursors, you can monitor its effectiveness via two more statistics in v$sesstat. The statistic “session cursor cache hits” reflects the number of times that a statement the session sent for parsing was found in the session cursor cache, meaning it didn’t have to be reparsed and your session didn’t have to search through the library cache for it. You can compare this to the statistic “parse count (total)”; subtract “session cursor cache hits” from “parse count (total)” to see the number of parses that actually occurred.

v$sesstat also provides a statistic to monitor the number of cursors each session has in its session cursor cache.

–session cached cursors, by session

select a.value, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s
where a.statistic# = b.statistic#  and s.sid=a.sid
and b.name = ‘session cursor cache count’ ;

–session cached cursor usage.

select a.value curr_cached, p.value max_cached, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s, v$parameter2 p
where a.statistic# = b.statistic#  and s.sid=a.sid
and p.name=’session_cached_cursors’
and b.name = ‘session cursor cache count‘

Above query gave a result that CUR_CACHED=MAX_CACHED . If the session cursor cache count is maxed out, session_cursor_cache_hits is low compared to all parses, and you suspect that the application is re-submitting the same queries for parsing repeatedly, then increasing SESSION_CURSOR_CACHE_COUNT will help with latch contention and can give boost to performance.

One fix is ready now i.e increase SESSION_CACHED_CURSOR from 100 to 300 (Decided to put 300 first and  monitor the session cursor caching).

We had a high hard parse rate as well – So the second parameters to play around was CURSOR_SHARING. For poorly coded application Oracle highly recomend to keep CURSOR_SHARING=FORCE . Also there are few bugs reported with CURSOR_SHARING=SIMILAR option as well as it is Deprecated from 11g onwards. [ANNOUNCEMENT: Deprecating the cursor_sharing = ‘SIMILAR’ setting [MOS Note ID 1169017.1]]

Conclusion :

Changed initialization parameters for session cached cursors and cursor sharing hence reduced library cache contention by avoiding parse calls and releasing cpu cycle.

I have changed to

CURSOR_SHARING=FORCE
SESSION_CACHED_CURSOR=300

Certaily you can dynamicaly do CURSOR_SHARING=FORCE

ALTER SYSTEM SET CURSOR_SHARING=FORCE SCOPE=BOTH;

But SESSION_CACHED_CURSOR is not dynamic and you need a bounce to reflects this. I was in trouble for this because it is a zero tolerence system and outage should be planned a month before. I cannot wait until that to tune this perf issue. Again there is anotehr back door method to implement SESSION_CACHED_CURSOR to get effect, but that’s a topic for another blog – you can see it in another post here ..

I have mentioned at the very start cursor parameters that can introduce  surprises. Yes, very true. After these two changes all the library cache contention was vanished.

Hard parses reduced from 58 per sec to 1 or 0 per sec. Library hit ratio become 98% and soft parse ration become 99%  and response time become jet fast.

This information is published by Don Burleson at http://www.dba-oracle.com. So this is just a copy to let our readers know about this issue.

Beware, following new upgrades to 11gR2, you can find that AMM has reappeared, even if you think that you have disabled it.

Oracle Automatic Shared Memory Management (ASMM) was introduced in Oracle 10g for small databases where a one-sized-fits-all approach was used in small hands-off databases that did not have a DBA to intelligently allocate the SGA pools.

When a small system has a too small RAM region for the SGA, Oracle AMM will cause a performance problem with RAM thrashing and it tries to readjust all of the RAM regions.

In all large mission-critical databases, the DBA will disable AMM because an intelligent human will always do a better job than a simple software solution, especially when you need to intelligently reconfigure the SGA in anticipation of a changing workload.

The following references will be helpful in researching the behavior of AMM:

• Never use AMM with Linux hugepages
• Review these important notes on when to turn AMM off.
• Consult related notes on using AMM in large production databases.

Disabling AMM in Oracle 11g Release 2

You can enable and disable AMM by changing the value of these parameters to non-zero settings:

• sga_target
• sga_max_size
• pga_aggregate_target
• sga_max_size
• db_cache_size
• shared_pool_size
• java_pool_size

nfortunately a new feature in 11gR2 turns AMM on unless a hidden parameter called _memory_imm_mode_without_autosga is set to FALSE.

Important 11gR2 Note:  Even if AMM has been disabled in Oracle 10g, AMM may reappear in Oracle 11g unless the following parameter is set:

alter system set “_memory_imm_mode_without_autosga”=FALSE scope=both;

There is a MOSC note about AMM in 11gR2 that notes that this regression back to AMM is the expected behavior in 11.2 for immediate memory allocation requests and that Oracle added this behavior as a 11gR2 new feature when automatic memory management was disabled.

The 11.2 Oracle support metalink  note on AMM regression is note number 1269139.1, titled:

SGA Re-Sizes Occurring Despite AMM/ASMM Being Disabled(MEMORY_TARGET/SGA_TARGET=0)

Some bullets – before moving to the try-out ->

Oracle RAT – Real Application Testing

• Introduced in Oracle 11.1

• Licensable option

• Includes
  • Database Replay
  • SQL Performance Analyzer

• Database Replay
  • Captures database workload on production system
  • Replays captured workload on test system
  • Optionally includes concurrency and timing characteristics
  • Generates reports and recommends changes

• SQL Performance Analyzer
  • Identifies performance divergence between workloads on source and target platforms
  • Generates tuning recommendations

Here are my try-out with Database Replay.

Database Replay

Requires the following steps:

• Capture workload into capture files

• Copy files to test system and pre-process them

• Replay files on test system

• Perform detailed analysis of workload capture and replay using reports generated by Database Replay

Potential scenarios where database replay may help:

• Testing operating system upgrades

• Testing database upgrades and migrations

• Testing parameter changes

• Evaluate migration from single-instance to RAC

• Testing storage changes

• Debugging

• Testing database manageability features

Capture Workload

• Create an operating system directory

• Create an Oracle directory

• Start the capture process

• Run the workload – Do some random works and transactions etc.

• Finish the capture process

Before a workload can be replayed, the application data state should be logically equivalent to that of the capture system at the start time of workload capture.If RMAN was used to back up the capture system, you can use RMAN DUPLICATE capabilities to create the test database.

Replay Preparation

• Copy the capture files to the target test database server

• On the target database – Pre process the captured workload

• Initialize the replay

• Prepare the replay

Workload Replay

• Copy the workload files to the client system. This could be the same target system or any other machine where 11g client is installed For eg:

• On the client , run the workload client to calibrate the replay

• The calibration process recommends the number of client processes required to perform the replay

• Replay the workload

• wrc – is a multithreaded program located in the $ORACLE_HOME/bin directory, where each thread submits a workload from a captured session.

• The client will not start to replay the workload until the replay has been started on the target database

• On the target database, start the replay process

• SQL> exec dbms_workload_replay.start_replay;

• When the replay process completes on the client, run the replay report

Forms performance issues may arise when dead connection persists on the server and consuming the server resources. Enable the forms dead client connection can eliminate the dead connection.

• FORMS60_TIMEOUT=10 (recommended value and value specified in minutes)

• Do $ ps –ef| grep f60webmx and terminates f60webmx processes for dead clients.

• Enable Forms Abnormal Termination Handler by enabling theFORMS60_CATCHTERM

• Deploy with socket mode for internal user.

• Form – Cancel Query Should not be enabled unless you are on Forms patch set 14 (Forms version 6.0.8.23.x or higher).Cancel Query increases middle-tier CPU as well as DB CPU. To disable the cancel query, Set the Profile “FND: Enable Cancel Query” to No.

• Tune the Cancel query features like
  • Export FORM60_LOV_INITIAL=32000
  • Export FORM60_LOV_MINIMUM=5000
  • Export FORM60_LOV_WEIGHT=0
  • These variables must be set in $APPL_TOP/.env or ‘formservlet.ini’ file.

• Ensure users are optimally utilizing the professional Forms interfaces and for that avoid opening and closing forms across transactions

• Avoid Blind queries

• Trace Form.
  • Open the problematic, Go to Menu > Help > diagnostics > Trace with waits and binds

Application Tier – Reports

• Ensure users provide selective parameters to the standard reports.

• Review the report output:
  • Number of rows returned to the report.
  • Number of report pages.

• SQL Trace can be generated at request submission time (SRS form – Debug Options) or by setting the “Enable Trace” flag in the concurrent program definition form.

Reports Tracing:

• If the SQL trace for the report does not account for the elapsed time of the request, then generate a reports trace by appending tracing parameters to the concurrent program command line.

• The following are the trace options:
  • TRACE_ALL: log all possible trace information in the trace file. (DEFAULT)
  • TRACE_APP: log traces information on all the report objects in the trace file.
  • TRACE_BRK: list breakpoints in the trace file.
  • TRACE_ERR: list error messages and warnings in the trace file.
  • TRACE_PLS : log traces information on all the PL/SQL objects in the trace file.
  • TRACE_PRF : log performance statistics in the trace file.
  • TRACE_SQL : log traces information on all the SQL in the trace file.
  • TRACE_TMS: enter a timestamp for each entry in the trace file.

• Enabling Reports Trace (pre 11.5.10)
  • Sign-on to Apps with System Administrator responsibility
  • Navigate to Concurrent -> Program -> Define Query the concurrent program (report) which you want to trace. Locate the “Options” field and enter the following values : TRACEOPTS= TRACEFILE
  • Save the concurrent program
  • Run the report and a trace file will be generated.
  • Remember to clear the trace options after running the report.

• Enabling Reports Trace (11.5.10)
  • Use the Debug Options page at request submission.

Architecture Comparison

• In Oracle AS 10g R3 Application Server Control is active on only one instance (identified as Administration instance in a cluster) even though it manages other associated Oracle AS instances. Similarly, in Oracle WebLogic Server the Administrative Console is active only on one server instance (Administration Server) but can manage other server instances (Managed Servers) in a domain.

• In Oracle AS 10g Release 2 there is a central configuration repository managed by Distributed Configuration Management (DCM). In Oracle WebLogic Server also there is a central configuration repository (config.xml).

• In Oracle AS 10g Release 2, all the instances that shared the configuration repository constituted a topology element called Farm. The Farm is similar to a Domain in Oracle WebLogic Server.

• The weblogic server is an instance of weblogic.server, which executes in a Java Virtual Machine (JVM). This is similar to an Oracle AS instance with just an OC4J container.

• Managed server is an oracle weblogic server instance that hosts business applications, application components, web services and associated resources. It is similar to an Oracle AS 10gR3 without the management components.

• Administration Server and OC4J Administration Instance – Administration Server stores the master copy of the domain configuration, including the configuration for all the Managed Servers in the domain. In this way, it functions as an Oracle AS instance that contains the file-based repository.

• An Oracle WebLogic Server cluster consists of multiple Oracle WebLogic Server instances. This is similar to an OC4J cluster in Oracle AS. When you configure an Oracle AS Cluster (OC4J), you can use the Oracle HTTP Server as the front end. The load balancing directives are configured in the mod_oc4j configuration of the front-end Oracle HTTP Server. When you configure an Oracle WLS cluster, you should configure a mechanism such as an Apache or a non-clustered WLS instance to function as the front end for the cluster. You should also configure the load balancing within the cluster and not at the front end.

Administration and Installation

• An Oracle Application Server has integrated installation and configuration where as Weblogic server separates installation of binaries using the installer and configuration of domains that contains the servers by using domain configuration wizard.

• Admin Console: A web application with GUI that is used to manage and monitor an active domain. This is similar to the Oracle Application Server Control Console.

• Weblogic Scripting Tool (WLST): A command line scripting interface that you use to manage and monitor an active or inactive weblogic server domain. This is similar to the OPMNCTL and DCMCTL tools but has more capabilities.

SQL> select INSTANCE_NAME from v$instance;

INSTANCE_NAME
—————-
+ASM

SQL> ALTER USER sys IDENTIFIED BY <new_password> REPLACE <old_password>;
ALTER USER sys IDENTIFIED BY <new_password> REPLACE <old_password>
*
ERROR at line 1:
ORA-01109: database not open

We can not change the password for ASM databases via alter user command.Because passwords are managed through password file in ASM. The password should be the one provided when the password file was created,also REMOTE_LOGIN_PASSWORDFILE should be set to EXCLUSIVE on all instances.

So only way to change password would be recreating the password file using orapwd utility or create another ASM DBA user to manage ASM instance. Remember only one default user [sys] will be present in ASM instance. Now if DBA decided to create another user to manage ASM instance, here are my tries

SQL> create user asmdba identified by test01;
create user asmdba identified by test01
*
ERROR at line 1:
ORA-15306: ASM password file update failed on at least one node

The ORA-15306 error demonstrates that the ASM password file is corrupt. Now remove all the ASM password file from each node. Create the ASM password file manually on the first node and copy to other nodes

Recreate the password file for the ASM instance as follows:

Unix:
orapwd file=<ORACLE_HOME>/dbs/PWD<SID> password=<sys_password>

Windows:
orapwd file=<ORACLE_HOME>/database/PWD<SID>.ora password=<sys_password>

Now sys password is reset, we are ready to use sys for ASM management. I decided to create another user ASMDBA as I tried above.

SQL> create user ASMDBA identified by test01;

User created.

SQL> grant SYSASM, SYSOPER to ASMDBA;

Grant succeeded.

SQL> select * from v$pwfile_users;

USERNAME SYSDBA SYSOPE SYSASM
—————————— —— —— ——
SYS TRUE TRUE TRUE
ASMDBA FALSE TRUE TRUE

Remember there is no DBA views you can access in ASM and only way to change password is through orapwd utility.

The Java Virtual Machine (JVM) is a virtual “execution engine” instance that executes the bytecodes in compiled Java class files. Java programs are compiled into a form called Java bytecodes. To the JVM, a stream of bytecodes is a sequence of instructions.

Tuning the JVM to achieve optimal application performance is one of the most critical aspects of  WebLogic Server performance.

Oracle recommends to use:
• Oracle JRockit JVM for production servers
• Sun HotSpot JVM for development servers and for running other WLS utilities

Setting Weblogic Server JVM Arguments:

If we want to use different JVM after domain creation is possible by setting some WLS JVM arguments.

Start JVM with Custom JVM settings.

export JAVA_VENDOR=”Oracle”
export USER_MEM_ARGS=”-Xms512m –Xmx1g”
./startWebLogic.sh

• “Oracle” indicates that you are using the JRockit SDK. It is valid only on platforms that supportJRockit.
• “Sun” indicates that you are using the Sun SDK.
• “HP” and “IBM” indicate that you are using SDKs that Hewlett Packard or IBM have provided. These values are valid only on platforms that support HP or IBM SDKs.

Basic Sun JVM Arguments :

• -XX:NewSize (default 2 MB): Default size of new generation (in bytes)
• -XX:MaxNewSize: Maximum size of new generation (in bytes). Since 1.4, MaxNewSize is computed as a function of NewRatio.
• -XX:NewRatio (default = 2): Ratio of new to old generation sizes
• -XX:SurvivorRatio (default = 8): Ratio of Eden size to one survivor space size.
• -XX:TargetSurvivorRatio (default = 50%): Desired percentage of survivor space used after scavenge
• -XX:MaxPermSize: Size of the permanent generation

Basic JRockit JVM Arguments:

• -Xms The initial amount of heap allocated to the JVM
• -Xmx The maximum amount of heap that this JVM can allocate
• -Xns Size of the nursery generation in the heap
• -XgcPrio A priority level that helps to determine which GC algorithms the JVM will use at run time:
• throughput: Maximize application throughput
• pausetime: Minimize how long GC runs
• deterministic: Consistent response times
• -XXcompactRatio The percentage of the heap

Common JVM Issues:

Out of Memory : JVMs trigger java.lang.OutOfMemoryError when there is insufficient memory to perform some task . An out-of-memory condition can occur when there is free memory available in the heap but it is too fragmented and not contiguously located to store the object being allocated or moved (as part of a garbage collection cycle).

Memory Leak : Are a common cause of out-of-memory errors, can occur because of  excessive caching.

JVM Crash: We can identify and troubleshoot a JVM crash by the diagnostic files that are generated by the JVM. A snapshot is created
that captures that state of the JVM process at the time of the error.

This binary file contains information about the entire JVM process and needs to be opened using debugging tools.
The gdb debugging tool, popular on Linux, can extract useful information from core files. The Dr.Watson tool on Windows provides similar capabilities.

On the Sun JVM, the log file is named hs_err_pid<pid>.log, where <pid> is the process ID of the process. JRockit refers to this error log as a “dump” file, and is named jrockit.<pid>.dump.

Basic JVM Tools:
– Stack Trace
– Thread Dump
– Verbose GC
– Sun Profiler Agent
– Sun Diagnostic Tools
– JVisualVM

Primavera provides a set of integrated components that meet the project management needs of different areas of an organization. It uses standard Windows interfaces, Web-enabled technology with application server and database support.

Primavera P6 can be implemented on a standalone or client/server machine. For the client/server implementation requires the installation and configuration of both client software and server-based components.

Primavera Server Component:

Primavera may require the installation and configuration of the following server-based components:

1. Database: Project data and project methodologies are each stored in separate central databases. These two databases should be maintained on a database server running Oracle.
2. Group Server: If your implementation of Primavera includes the Timesheets client module, you must install the Group Server. This component is a Windows 2003 service that runs on your Web server and allows clients to download Timesheets from that server using their Web browsers.

Primavera Client Component:

The Primavera P6 solution consists of the following client modules:

1. Project Management: Project Management is a module that enables users to plan and control a large number of projects.
2. Methodology Management: Methodology Management is a module for authoring and storing methodologies, or project plan templates.
3. Timesheets: Timesheets is a Web-based inter-project communication and timekeeping system

Additional Components:

Primavera implementation may require the installation of one or more optional components. These additional components expand the functionality of the Primavera solution:

1. P6 Web Access: P6 Web Access provides browser-based access to project, portfolio, and resource data across the enterprise. Every P6 Web Access user can customize dashboards to create an individualized and focused view of the specific projects and categories of project data that are most relevant to their role in managing projects and resources.
2. (Distributed) Job Service: The Job Service is a Windows 2003/ 2008 service that runs defined jobs on project data at preconfigured intervals. Users create jobs in the Project Management module. The job details are stored in the central project management database. The Job Service periodically reads the database and performs jobs as directed. This service must run on a server that has a constant connection to the database server.
3. ProjectLink: ProjectLink is a plug-in that enables Microsoft Project (MSP) users to work in the MSP environment while being connected to Primavera’s enterprise features.
4. SDK (Software Development Kit): The SDK enables you to integrate the data in the project management database with external databases and applications. It provides access to the schema and to business logic. The SDK supports the Open Database Connectivity (ODBC) standard and ODBC-compliant interfaces, such as OLE DB, for connecting to the project management database. The SDK may be installed on any computer that needs to integrate with the Primavera database.

P6 Configuration and Component requirements

The following table lists each client component and the corresponding server-based components that it requires.

Note:-

• If using Oracle as the RDBMS, these modules require the Oracle client software to be installed on the client computer.
• The Job Service is an optional component for the Project Management module.
• The Group Server is an optional component for P6 Web Access; it is required if you are using the Timesheets functionality of P6 Web Access.
• P6 Web Access is an optional component for Timesheets and is only required if resource timesheets must be reviewed and approved.
• The Content and Workflows Repositories are optional components of P6 Web Access. They can serve as aids in document management and project request processes
