Yes, even when Ideal is not in use in a CICS region, the four "ADR" files ADRLIB, ADRPNL, ADROUT, and ADRTRC are needed by IPC in a CICS region that is used for Datacom access by transactions such as DDOL.
VLS file ADRLIB to contain the messages from the Datacom installation and the IPC installation.
VLS file ADRPNL to contain the Datacom DDOL panels from the Datacom/DB installation.
VLS file ADROUT formatted and initialized.
VLS file ADRTRC formatted and initialized.
When installing or upgrading IPC, either new installation job VQNEW01 or upgrade installation job VQUPG01 is run on each CICS region to format, initialize.
