DFS4596E OLC COMMIT REJECTED. INVALID MEMBER IN FMTLIB ddname -nn mbrname

Explanation

An online change commit command, /MODIFY COMMIT, was rejected because an invalid member was detected in the inactive FMTLIB data set. The member is invalid because it contains an invalid directory size; that is, the directory size is negative or greater than 32767 bytes.
In the message text:
ddname
The 7-character FMTLIB DD name, which is either FORMATA or FORMATB.
nn
The 2-byte FMTLIB data set concatenation number within the FMTLIB DD statement.
mbrname
The 8-character invalid member name in the FMTLIB data set.
For example, if a module is erroneously copied into the inactive FMTLIB before the /MODIFY COMMIT command is issued, the /MODIFY COMMIT command might fail with this error. If the member is an actual MFS format with an invalid directory size, the first two characters of the format name are unprintable hexadecimal values that might appear as blanks or other non-alphanumeric characters in this output. The first two characters of the format name might appear as different non-alphanumeric characters when browsing the FMTLIB with TSO.

System action

The online change commit command is rejected.

Output destination of message

The message is sent to the z/OS system console.

Operator response

Delete the invalid member from the FMTLIB data set and either reissue the /MODIFY COMMIT command or abort the online change by using the /MODIFY ABORT command.
