IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Customize RMI garbage collection interval
If the data collector communicates with ITCAM for Application Diagnostics Managing Server, it uses RMI over TCP/IP for this communication. One effect of using RMI is that garbage collection occurs every minute. If you don't want this to happen, you can specify the garbage collection interval explicitly to a preferred interval.
The data collector communicates with the Managing Server using TCP/IP sockets and RMI. One effect of using RMI is that garbage collection occurs every minute. If you don't want this to happen, you can specify the garbage collection interval explicitly to a preferred interval by specifying the parameters in the Generic JVM arguments field. These parameters must be implemented as a pair.
Log into the WAS administrative console and click...
Server | Application Servers | server_name | Configuration tab | Server Infrastructure | Java and Process Management | Process Definition | Additional Properties: Java Virtual Machine
In the Generic JVM arguments field, append the following parameters if such parameters don't exist, or update their values if they already exist.
-Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
These values require a dash (-) in front of each parameter, and a single space between parameters. You must specify both parameters if you specify them at all. The value is in milliseconds; 3,600,000 represents one hour.
