Issue:
Due to other circumstances, the physical size of the non-virtual CBS Heuristics index (IXX1006) needed to be enlarged and switched to a different, larger data set.
Attempt to then run DBUTLTY to rebuild the index via RETIX failed with RC 46.
 
Environment:
z/OS
Cause:
RETIX failed with RC 46 since base 1006 was open in MUF via the MUF startop option CBS specifying the heuristic-dbid 1006.

For example:

CBS        6,2M,0,0,16,1006 
Resolution:
The situation was resolved by restarting the MUF with startup option LIMITED_INSTALL_MUF which enabled MUF without opening some system databases.
This allowed RETIX to run.
After RETIX, the MUF was recycled again with out LIMITED_INSTALL_MUF to return to desired functioning.

  • LIMITED_INSTALL_MUF
    If LIMITED_INSTALL_MUF is specified as YES to block options that can cause known conflicts, actions during MUF startup that are different include the following:
    • The temporary CBS index is not automatically opened.
    • All URT open requests fail with a return code 94(167), except all DBUTLTY functions are allowed and the CA Datacom® Datadictionary™ databases are allowed.
    • Message DB01919E - CONFLICT WITH LIMITED_INSTALL_MUF is received if any of the following options are placed in MUF startup:
      • ACCT
      • ACCTPRM
      • CBS
      • CBS_DBID_TEMP
      • CDCL
      • HISTORY
      • SQL_OPTION
      • STAR
      • SYSTEMDBID

Note: Do not specify the CBS MUF startup option when you specify YES for the LIMITED_INSTALL_MUF MUF startup option. LIMITED_INSTALL_MUF YES prevents the CBS temporary index from being automatically opened. For more information, see LIMITED_INSTALL_MUF
