IDC11768I [CI SPLIT | CA RECLAIM] IN PROGRESS

Explanation
Some situations, such as an ABEND,
CANCEL, or a system failure, can interrupt a control interval (CI)
split or a control area (CA) reclaim for an ERASE request.
An interrupted split results in VSAM backing out the
CI split that is in progress and returning a nonzero return code to
the PUT request that caused the CI split. When a CI split is aborted
under this condition, the copy of the new CI or CA (commonly referred
to as an orphan CI or CA) is left behind within the data set. This
does not indicate there is a data integrity problem.
A
CA reclaim interrupted at this stage will not leave behind an orphan
CI or CA and there are no data integrity problems.
This
message is generated when the interruption occurred at a different
point of the CA reclaim processing than message IDC11778I CA RECLAIM
IN PROGRESS. The two messages are mutually        exclusive.

System action
The condition is temporary. The
data control interval is dumped in a subsequent IDC01720I message.
 Processing continues.

Programmer response
The condition is temporary.
For CA RECLAIM IN PROGRESS, this IDC11768I message indicates
an interruption very early in the VSAM CA reclaim process where no
index CIs have been changed. For that reason, IDCAMS VERIFY RECOVER
might not be able to complete or back out the CA reclaim process.
Subsequent VSAM or VSAM RLS requests that encounter the data CI involved
in the interrupted CA reclaim will back out the CA reclaim process,
even if SETSMS CA_RECLAIM(NONE) is issued.
