OIM, OAM performance monitroing and matrics Java Flight Recorder

In this post I will cover the steps that are required to monitor and record a running jvm process using java flight recorder.

The flight recorder can be used to monitor the running jvm processes and giving us the statistics on cpu utilization, ram usage etc for the its running duration.


here are the commands

step 1 list java processes

ps -ef | grep java

user 23639 23615   3   Jul 24 ?        12083:48 /app/oracle/fusionV11gR2/jdk1.7.0_40/bin/sparcv9/java -server -Xms256m -Xmx512m
user 23614 23590   3   Jul 24 ?        9422:12 /app/oracle/fusionV11gR2/jdk1.7.0_40/bin/sparcv9/java -server -Xms256m -Xmx512m
user 23664 23640   4   Jul 24 ?        4463:27 /app/oracle/fusionV11gR2/jdk1.7.0_40/bin/sparcv9/java -server -Xms256m -Xmx512m

step 2 confirm the java processes with jcmd command

cd /app/oracle/fusionV11gR2/jdk1.7.0_40/bin/sparcv9

./jcmd

23614 weblogic.Server

23664 weblogic.Server

23639 weblogic.Server

Step 3 record the running process performance for time duration that you wish to analyze later

./jcmd 23614 JFR.start name=23614 duration=900s filename=/tmp/23614.jfr settings=default

So above command will monitor the existing java processes with PID=23614 for 15 minutes and then stop.

.jfr can be opened with out-of-the-box java mission control tool to analyze the process statistics during that process run.

OVD 11.1.1.7.0 Add Instance

In this post, I will cover the steps required to add an instance of OVD to an existing OVD installation home.

This kind of configuration is specially helpful in scenario where you want to add instances for load balancing or to create an instance for testing etc.

My existing OVD setup was 11.1.1.7.0.

ORACLE_HOME=C:\Oracle\Middleware\Oracle_IDM2
ORACLE_INSTANCE=C:\Oracle\Middleware\asinst_2

set of existing running processes

                                                                                                                                              

we will have to use the opmnctl command inside ORACLE_INSTANCE. Also weblogic admin server must be running prior to adding an instance as the command connects to weblogic server to register the component.

opmnctl.bat createcomponent  -componentName ovd2 -componentType OVD -admin cn=orcladmin -isAdminSSL true -ovdAdminPort 8900   -namespace dc=mydomain,dc=com -ldapPort 6502 -ldapSport 7502

Command requires login to weblogic admin server (Deepak-PC.mydomain.com):

  Username: weblogic

  Password:

Creating empty component directories...Done

Provisioning OVD files for ovd2

  OVD creation in progress

  Creating OVD specific directories

  Copying Configuration Files

  Registering OVD Ports

  Updating OVD Admin Password

OVD Admin Password:

  Setting CSF values

  Updating Configuration Files

  Adding opmn Snippet

  Setting proxy mbean information

Registering ovd2 component

Command succeeded.

                                                                                                                                                                                                    

Also while starting the processes i found out that my computer has changed the timezone.

commands to fix that error

Start all the opmn processes now

You can use ODSM to login to OVD now
