Is ADRLIB needed in a Datacom CICS region that is not using CA Ideal?
Yes, even when CA Ideal is not in use in CICS region, the four "ADR" files ADRLIB, ADRPNL, ADROUT, and ADRTRC are needed by CA IPC in a CICS region that used for CA Datacom access by transactions such as DDOL.
VLS file ADRLIB to contain the messages from the Datacom installation and the CA IPC installation.
VLS file ADRPNL to contain the Datacom DDOL panels from the Datacom/DB installation.
VLS file ADROUT formatted and initialized.

When installing or upgrading CA IPC, either new installation job VQNEW01 or upgrade installation job VQUPG01 is run on each CICS region to format, initialize.
