InstantDB tracing

InstantDB places its tracing information in the file:

product_installation_root/bin/trace.log
where product_installation_root refers to the IBM WebSphere Application Server installation root.

To turn logging off:

  1. Open the following file in a text editor: product_installation_root/bin/was.prp
  2. Locate the line:
    traceFile=./trace.log
    
  3. Comment the line out:
    ! traceFile=./trace.log
