Building indexes and ILDSs for IMS catalog databases

IMS™ Index Builder treats an IMS catalog database as a PHIDAM database. Primary indexes, secondary indexes, and indirect list data sets (ILDSs) for IMS catalog databases are rebuilt the same way PHIDAM indexes are built.

Procedure

When building IMS catalog indexes and ILDSs, the following JCL and control statement requirements might apply depending on the usage scenario:

  

Place the IMS Catalog Definition exit routine (DFS3CDX0) in the STEPLIB DD concatenation in the following cases:
  • If the IMS catalog database partitions are defined by using the IMS Catalog Partition Definition Data Set utility (DFS3UCD0) instead of by using DBRC.
  • If an IMS catalog alias name other than ALIAS=DFSC is defined.
If the IMS Catalog Partition Definition Data Set utility (DFS3UCD0) is used, specify the statements as follows:
  • Specify DBRC=N on the INPUT control statement.
  • If the MDA member for the HALDB partition definition data set (DFSHDBSC) is used, specify the library on the STEPLIB DD statement, not on the IMSDALIB DD statement.
