After binding the product packages and plans on post-installation of CA Database Management Solution for DB2, the submitted JCL, EXECRBP1 created some data sets under the userid qualifier. Here are some examples:
Why that JCL created these data sets and is it okay to delete them?
The .DATA datasets are purely work files required for the ssid0001 execution. Once this job completes normally, as it did, they can be safely deleted. The .COPY datasets are image copies of the respective tablespaces that can be used for recovery if required. I really do not see that you would need the .COPY datasets as well. You can likely scratch the .COPY datasets as well. You may have a production type job that takes image copies of database PTDB for recovery purposes.
