The CSDJID parameter specifies the journal identifier of the journal that you want CICS to use for automatic journaling of file requests against the CSD.
The automatic journaling options enforced for the CSD when you code CSDJID=number are JNLADD=BEFORE and JNLUPDATE=YES. These options are sufficient to record enough information for a user-written forward recovery utility. No other automatic journaling options are available for the CSD. For information about the options JNLADD=BEFORE and JNLUPDATE=YES, see FILE definition attributes.
