Dual data set considerations
data set switching messages
Data set switching messages can be seen in the BBI-SS joblog and the BBI-SS journal. The messages are documented under the MESSAGES service (MSG msg#).
Online access of CMRDETL data
The selection criteria specified in the online History service determines which data set to read.
batch processing of CMRDETL data sets
Batch jobs should never be run against the inactive CMRDETL data set. For example, if a Performance Reporting Language (PRL) program uses CMRDETL data, the job must run against either the active data set or an archived copy of the inactive data set. Your batch job can fail if it is actively selecting records from the inactive CMRDETL data set when a switch occurs.
If necessary, the primary and archived data can be REPROed with IDCAMS into a single file for batch processing.
