DFS3410I DATA SETS USED ARE DDNAME acblib-name format-name 'MODBLKS-name' (time/date stamps if they exist)

Explanation

The indicated ddnames are the ones which are used for IMS online processing. If time/date stamps exist, they indicate when the last successful INITIATE OLC PHASE(PREPARE) or /MODIFY PREPARE and INITIATE OLC PHASE(COMMIT) or /MODIFY COMMIT commands were issued.

In the message text:
acblib-name
The active IMSACB DD in the IMS JCL, which identifies the active ACBLIB library. The acblib-name ddname is either IMSACBA or IMSACBB.
Note: If the IMS management of ACBs is enabled in this IMS system by the specification of ACBMGMT=CATALOG in the DFSDFxxx PROCLIB member, disregard the ACB library ddname. IMS systems that manage ACBs do not use either the IMSACBA or IMSACBN ddnames for any libraries.
format-name
The active FORMAT DD in the IMS JCL, which identifies the active MFS format library. The format-name is either FORMATA or FORMATB. If this system is DBCTL, format-name is blank.
modblks-name
The active MODBLKS DD in the IMS JCL, which identifies the active MODBLKS library. The modblks-name is either MODBLKSA or MODBLKSB.

modblks-name can be blank. If modblks-name is blank, then MODBLKS DD is not defined in the IMS JCL. The MODBLKS DD statements are optional when dynamic resource definition is enabled.
