400 IBM Content Manager OnDemand Guide
18.3.1  Enabling the trace facility
This information is also covered in the Technote How to enable trace in Content Manager 
OnDemand server, 1330810.
To enable the server trace facility, complete the following steps:
1. Locate your trace.settings file:
– On AIX, it is in the /opt/IBM/ondemand/V9.5/config directory.
– On Sun, it is in the  /opt/IBM/ondemand/V9.5/config directory.
– On Windows, it is in the C:\Program Files\IBM\OnDemand Server\V9.5\config 
directory.
– On z/OS, it is in the /SYSTEM/etc/ars directory.
– On other platforms, it is in the /opt/ondemand/v9.5/config directory.
2. Edit the trace.settings file to trace server startup routines by setting the following trace 
parameter:
TRACE_LEVELS=ALL=15 
3. Edit your ars.cfg file by adding the ARS_TRACE_SETTINGS parameter and referencing the 
full path to your trace.settings file:
ARS_TRACE_SETTINGS=/usr/lpp/ars/V9R0M0/config/trace.settings 
For Windows, the ars.cfg configuration is in the registry. Edit the registry settings for the 
registry key HKEY_LOCAL_MACHINE\SOFTWARE\IBM\OnDemand for WinNT\@SRV@_ARCHIVE\CFG, 
where ARCHIVE is the name of your Content Manager OnDemand instance. Create a string 
value ARS_TRACE_SETTINGS and set the value to the full path to your trace.settings file. 
After you enable tracing, start the Content Manager OnDemand Administrator Client.
18.3.2  Setting trace parameters
After you enable tracing, you can set the appropriate option for a runtime trace by using the 
Content Manager OnDemand Administrator Client.

Do not use trace as a programming interface.
