DFSMShsm: Review messages changed from I (informational) to E (eventual action) type

Description: Before z/OS V1R13, messages ARC0036, ARC0503, and ARC0704 were informational messages (ending in the letter "I"). Starting with z/OS V1R13, messages ARC0036, ARC0503, and ARC0704 are reclassified as eventual action messages (ending in the letter "E"). The meaning of the messages is unchanged. The type is changed only.

Each of these messages indicate a significant error has occurred and are more easily identifiable as eventual action messages.

Message ARC0036E indicates that an I/O error occurred when writing to the PDA output data set.
Message ARC0503E indicates a dynamic allocation error.
Message ARC0704E indicates a VTOC copy data set processing error during volume backup, dump, or recovery.

These changes can affect applications that depend on message ARC0036I, ARC0503I, or ARC0704I and applications triggered by message type.

Element or feature:

DFSMShsm.

When change was introduced:

z/OS V1R13.

Applies to migration from:

z/OS V1R12.

Timing:

Before the first IPL of z/OS V2R1.

Is the migration action required?

Yes, if your applications depend on message ARC0036I, ARC0503I, or ARC0704I or if your applications are triggered by message type.

Target system hardware requirements:

None.

Target system software requirements:

None.

Other system (coexistence or fallback) requirements:

None.

Restrictions:

None.

System impacts:

None.

Related IBM Health Checker for z/OS check:

None.

Steps to take: Update applications that:

depend on ARC0036I to work with ARC0036E.
depend on ARC0503I to work with ARC0503E.
depend on ARC0704I to work with ARC0704E.
