11.6.2 Library Server performance tracing

To enable Library Server performance tracing, run the script in Example 11-10.

Example 11-10 Sample DB2 script to enable Library Server performance trace

db2 connect to icmnlsdb user icmadmin

db2 update icmstsyscontrol set tracelevel=-8

db2 update icmstsyscontrol set keeptraceopen=1

db2 connect reset

The trace data will go into the file specified in the system administration client.

On Windows, the default is c:\ICMServer.log.

To turn off the Library Server performance trace, run the script in Example 11-11.

Example 11-11 Sample DB2 script to turn off Library Server performance trace

db2 connect to icmnlsdb user icmadmin

db2 update icmstsyscontrol set tracelevel=0

db2 update icmstsyscontrol set keeptraceopen=0

db2 connect reset

11.6.3 Resource Manager performance tracing

Resource Manager logging is controlled by the XML file, icmrm_loggin.xml, in the

WebSphere\AppServer\InstalledApps\ICMRM_App.ear\icmrm.war directory. The

priority value in the XML file can be used to turn on performance tracing.

Note: Log configuration settings (key and value) are case sensitive. Trailing

blanks following the value fields are not allowed.

346 Performance Tuning for Content Manager

The priority value has the following possible values:

FATAL Only logs if the servlet is terminating unexpectedly.

ACTION Logs messages that describe an action the System

Administrator has to take. These are not errors but

conditions such as low space.

ERROR Logs a request that was unable to be fulfilled or an

internal error.

WARN Logs warnings of unexpected behavior.

INFO Logs informational start and stop messages.

BEGINEND Time markers begin and end for performance measures.

REQUEST Logs detailed information about the incoming request.

RESPONSE Logs detailed information about the outgoing response.

TRACE Logs general flow messages.

DEBUG Logs detailed debugging information, plus all other levels.

The traced data will go to ibmrm.logfile in the \WebSphere\AppServer\logs

directory. You can direct it to another file within this XML file:

<param name="File"

value="C:/WEBSPH~1/APPSER~1/logs/icmrm/icmrm.logfile"/>

To enable Resource Manager performance trace:

1. Open the icmrm_loggin.xml file (in the

WebSphere\AppServer\InstalledApps\ICMRM_App.ear\icmrm.war directory)

to edit using Notepad or another applicable editor.

2. Set <priority value=”BEGINEND”>

3. Stop and restart your system.

To turn off the Resource Manager performance trace:

1. Open the icmrm_loggin.xml file to edit using Notepad or another applicable
