Issue:

After upgrading to Datacom 15.0/15.1, I'm getting error DB01409E - DATA SET NAME MISMATCH on the CXX during MUF startup.

DB01409E - DATA SET NAME MISMATCH CXX-DATACOM.R14.MUF2.CXX DBSIDPR-DATACOM.R15.MUF2.CXX 

DB00501E - OPEN ERROR - RETURN CODE 76 (013) CXX= (CXX ) 

AD15STRT - ABEND=S000 U0004 REASON=00000000 715 

Cause:

The error message is due to checks made when using SIMPLIFY mode. This is activated in DBSIDPR with SIMPLIFY_MODE=YES.

The problem is the dastaset name of the CXX does not match the pattern specified in the  DBSIDPR DSN_XXX= parameter.

This parameter also applies to the dataset names of the LXX, and FXX so the error message could also refer to the LXX or FXX. 

For example in this message:

DB01409E - DATA SET NAME MISMATCH CXX-DATACOM.R14.MUF2.CXX DBSIDPR-DATACOM.R15.MUF2.CXX

It means in DBSIDPR you coded DSN_XXX=DATACOM.R15.MUF2.???

So the CXX has to be named DATACOM.R15.MUF2.CXX but it is named DATACOM.R14.MUF2.CXX

 

 

Resolution:

To resolve this you need to either:

  • Change the dataset name of the CXX, LXX or FXX to match the pattern specified in DSN_XXX
  • Change the pattern in the DSN_XXX= parameter to match existing dataset names then re-assemble and link the DBSIPDR module.
