Limitations ( internal )

How to monitor the memory limitation of the Performance Analyzer agent on an AIX server.

Some of the commands.

prtconf
will tell the memory size of the server.


System Model: IBM,9117-MMA
Machine Serial Number: 105BD0D
Processor Type: PowerPC_POWER6
Processor Implementation Mode: POWER 6
Processor Version: PV_6_Compat
Number Of Processors: 4
Processor Clock Speed: 4208 MHz
CPU Type: 64-bit
Kernel Type: 64-bit
LPAR Info: 7 va10tuvtdw001
Memory Size: 8192 MB
Good Memory Size: 8192 MB
Platform Firmware level: EM350_063
Firmware Version: IBM,EM350_063
Console Login: enable
Auto Restart: true
Full Core: false




PA can handle upto 10,000 agents on a 32 or a 64 bit platform.
(62+803+392+1814+7265) + 201 [vmware] = 10537 = PA meets the threshold.  (note: this is far more than the 2k, and just above the 10K test agents)

On the other hand:
(62+803+392+1814+7265) + 0[vmware] = 10336 =  PA can handle but almost there.


tacmd listsystems

to get the list of all configured agents.

tacmd login -s `hostname` -u sysadmin                                  
                                                                       
tacmd listSystems ( I believe you have to run with a flag  -v option )



bootinfo -k    

# bootinfo -k

LDR_CNTRL=MAXDATA=0x80000000  This allows upto 2GB of heap space.      
KPA_JAVA_ARGS=-Xms16m -Xmx500m                                          
                 


$ grep -i ldr_cntrl /opt/IBM/ITM/config/pa.ini

ps -ef |grep kpacma <== get the pid of the process                      
                                                                       
svmon -P <pid of kpacma process >  -O summary=basic,unit=GB            
                                                                       
(this will tell how much of the memory above is used by kpacma.)  


# ps -ef |grep kpacma

Production ITM Environment

1 Hub server
10 RTEMS where WPA is installed
1 Administrative TEPS
1 R/O TEPS
1 TDW server where DB2, SPA and TPA are installed
1 TCR/Cognos server

Test ITM Environment

1 Hub server where Administrative TEPS is installed as well
1 RTEMS where WPA is installed
1 TDW server where DB2, SPA, TPA and TCR/Cognos are installed


2. Number of Oracle and DB2 agents in ITPA.

We are collecting data for 98 Oracle agents out of 391

We are collecting DB2 data for all 61 DB2 agents

Here's what I found in my enviroment , that the "InUse" Memory starts to build up from 0 ...500 M .......1 Gb......... all the way upto 2 GB ~ and when all the  "Available memory  gets used up, the itpa dies
