PROCSEQ keyword
PFXAGEN lets you use the PROCSEQ keyword on the PCB that is associated with a primary DEDB. PFXAGEN processes and updates the
BMC AMI Fast Path Indexer for IMS
control blocks and extracts the PROCSEQ keyword from the PCB.
To specify the PROCSEQ keyword in your application PSB, perform one of the following tasks:
Specify the PFX index database name for the alternate processing sequence, as shown in the following example:
PCB DBDNAME=DIVSSD,PROCOPT=A,PROCSEQ=DIVSI4
Specify a wildcard (*) for dynamic index selection, as shown in the following example:
PCB DBDNAME=DIVSSD,PROCOPT=A,PROCSEQ=*The wildcard allows PFXAGEN to process multiple PFX indexes when only one PCB within the PSB is specified.
When you specify a wildcard, BMC AMI Fast Path Indexer for IMS analyzes the first SSA for a retrieval call. The product determines which PFX index to use as follows:
- If the segment named in the SSA is the target segment for a PFX index, and if the first field name specified in the SSA matches the name of the PFXXDFLD for the PFX index, BMC AMI Fast Path Indexer for IMS uses that PFX index.
- Otherwise, BMC AMI Fast Path Indexer for IMS does not use a PFX index for the call.
