Specifying the log head size

Specify the log head size by adding a system environment variable CUSTOM_LOG_HEAD_SIZE to px-runtime instance.

For example, when the log event size exceeds 1000 and the job run is still in progress, use the following command to display only the first 2000 lines.

oc set env deploy/inst1-ibm-datastage-px-runtime CUSTOM_LOG_HEAD_SIZE=2000
