Considerations for using Output Manager and other SAPI-based applications
If more than one SAPI-based application is attempting to operate on the same JES spool job at the same time, results may be unpredictable. For example, if you have an existing ISV product that is capturing SYSOUT class "Q" output, do not configure Output Manager to process class "Q" output as well. If both ISV products are configured to capture the same SYSOUT class output, the output may appear in Output Manager or the other product’s database.
To perform parallel testing with Output Manager and another ISV product, allow Output Manager to capture the output and leave a copy on the spool for the other ISV product.
To configure Output Manager to capture the output and leave a copy on the spool, change the JCL of the test job to use a SYSOUT class managed by Output Manager. When defining the Output Manager selector rule, specify the KEEP in a different class.
