Saving data

The dependency and affinity data collected by the Collector is saved to CICS® IA VSAM files by the autosave transaction, CINB.

For more information about these files, see The dependency data and affinity data VSAM files.

The CINB transaction is invoked automatically by CICS; it is not a user transaction. The CINB transaction is invoked in a number of ways: The CINB transaction saves dependency and affinity data automatically when you stop the Collector. You can also specify that data is saved as follows:

After the CINB transaction has saved any data collected, it either becomes dormant until next activated while the Collector is still running, or pauses or terminates if the Collector has been stopped.

Only the CICS, DB2®, IMS™, MQ, affinity, and resource detail tables in the data space need to be saved. The DTP and MQX tables are not saved because they hold only temporary data about DTP conversations and MQ queue names. Also, when data is saved, only those table elements that have been added or changed since the last save are written to the file. Time stamps in each table element indicate whether the element has been written already, and whether it has changed since the last write, to minimize the number of writes performed.
