Library Procedure Error Messages

26 MESSAGE Lock not performed since deadlock would

result.

MEANING If it is a self-deadlock, the database or data set is already

locked by the same process but with a different open

count. If it is locked by another process, it is because of the

DBLOCK call from another user that the real deadlock is

encountered.

ACTION To avoid the self-deadlock, modify the program. If it is a

real deadlock caused by another process, call DBUNLOCK.

Use the SHOW

dbname

LOCKS command of DBUTIL on all

databases that the process has opened in order to

determine the source of the deadlock.

41 MESSAGE DBUPDATE attempted to modify value of

critical item--key, search or sort (See below for

additional status code 41 messages.)

MEANING DBUPDATE has been asked to change the value of a master

data set key item or a detail data set search or sort item.

For master data sets and regardless of the critical item

update (CIUPDATE) option settings for the database and

the current process, this message is always returned if you

attempt to use DBUPDATE on key items. For detail data

sets, this message is returned when you attempt to use

DBUPDATE on a search or sort item and the CIUPDATE

option setting for the database or a particular process does

not permit this type of modiﬁcation.

ACTION Correct call, or notify user that item cannot be updated.

For detail data sets only, the application can be redesigned

to use the CIUPDATE option.
