You started the specified DB2 ECCR when a DB2 ECCR with the same name is already running. You cannot run more than one DB2 ECCR with the same name. If you need to run multiple DB2 ECCRs at the same time, they must have different names.
The second DB2 ECCR with the same name abends.
If you need to run multiple DB2 ECCRs in parallel, assign a different name to each DB2 ECCR. Specify the name of the DB2 ECCR in the NAME= keyword parameter of the CA control record in the //REPL2CTL file. Also, provide each DB2 ECCR running in parallel with a different capture directory table and a different DB2 plan.
