Error Messages
Library Procedure Error Messages
41 MESSAGE DBUPDATE: Full automatic master for path
decimal integer: nn
(See above and below for
additional status code 41 messages.)
MEANING Automatic master data set is full. User has called
DBUPDATE to update a search item in a detail data set, and
the corresponding key item value could not be added to the
automatic master data set. The digits nn identify the
offending path number established by the sequence in
which the detail data set search items appear in the set
part of the schema. This message is associated with the
critical item update (CIUPDATE) option; see chapter 4 for
information about this option.
ACTION Your database administrator needs to restructure the
database, increasing the capacity of the automatic master
data set. Refer to chapter 8 in this manual for information
on database restructuring.
41 MESSAGE DBUPDATE: Full automatic master synonym chain
for path
decimal integer: nn
(See above for
additional status code 41 messages.)
MEANING User has called DBUPDATE to update a detail data set
search item associated with an automatic master data set
that cannot accommodate another new value on the
synonym chain for that path number. The digits nn
identify the offending path number established by the
sequence in which the detail data set search items appear
in the set part of the schema. This message is associated
with the critical item update (CIUPDATE) option; see
chapter 4 for information about this option.
ACTION Ask your database administrator to verify that the
synonym chain is indeed full and inspect your database for
possible structural damage.
42 MESSAGE Read only item
MEANING DBUPDATE has been asked to change the value of a data
item for which the user does not have write access.
ACTION Notify user, cannot update item. Or change password in
program.
