Issue:
After changing the CXX name the following  MUF error occurs:
DB00501E - OPEN ERROR - RETURN CODE 43 (002) CXX=cxx_new_name (IXX01006) CXXLINK=cxx_old_name

 

 

Cause:
The RC 43 (002) indicates the database file is linked to a different CXX. Datacom keeps a connection between the CXX and the database files using the CXX name. In the above error message, the files is linked to a CXX named cxx_old_name  but the CXX is named cxx_new_name.
Resolution:

To link a file to the new CXX name run DBUTLTY with the LINK function, all files for all DBIDs defined in the CXX need to be linked, use the following syntax:

LINK DBID=1-5000

The Datacom MUF must be active to run this. Note any areas defined as VIRTUAL will fail to link and this is OK. 
A temporary change to the MUF startup is needed if DBID 1006 is used.  In the MUF startup parameters remove the 1006 at the end of the CBS card. Add it back after running the LINK and restart the MUF.
Sample JCL:

//LINK EXEC PGM=DBUTLTY,REGION=6M 
//STEPLIB  DD DISP=SHR,DSN=DATACOM.CUSLIB 
//         DD DISP=SHR,DSN=DATACOM.CABDLOAD  (for Datacom/AD use CAAXLOAD) 
//SYSPRINT DD SYSOUT=* 
//SYSOUT   DD SYSOUT=* 
//SYSPUNCH DD DUMMY 
//CXX      DD DSN=DSN=DATACOM.CXX,DISP=SHR 
//SYSIN    DD * 
LINK DBID=1-5000
