Figure 10: BPSIA system environment
BPSIA can also be started online. The DBDIR is then flagged as being inconsistent. A warning is issued, saying that the SYSTEM-BREAK-BIT in DBDIR is set.
When you run BPSIA online, you must assume that the data output is not current since the DBH has not copied all the data from the buffer to the database yet. In order to obtain as much current data as possible, you should force a database update just before the BPSIA run using the DAL command CHECKPOINT or NEW RLOG. However, the BPSIA output may still differ from the actual contents of the database if an update is running parallel to this task.
At startup BPSIA takes into account any assigned UDS/SQL pubset declaration (see the “Database Operation” manual, Pubset declaration job variable). Faulty assignment leads to the program aborting.
