Cause. This message is issued when DP2 is unable to allocate lock table space. The
message is preceded by event message ZDSK-EVT-NO-LKTABLE-SPACE (5071),
which indicates that DP2 failed to obtain additional space for its lock tables, and by
event message ZDSK-EVT-LK-TABLE-USE (5072), which provides information on the
amount of space currently in use by the combined lock tables.
The LAB table must fit within the space defined for all lock tables at initialization. The
default space allocation for all lock tables is 1.5 Mb. You can increase this allocation as
described under “Recovery.”
Effect. Requests to open or access files on the DP2 volume might incur allocation
errors (33 or 35).
Recovery. This event typically coincides with space allocation errors being returned to
the application. There are two possible methods to prevent these errors:

Redistribute files and tables to reduce the demand for the volume that incurred the
space allocation errors.

In the CONFTEXT configuration file, add or change the LKTABLESPACELEN
modifier for the volume that incurred the space allocation errors to increase the
amount of space available for lock tables. If the LKIDLONG pool has a current size
equal to the maximum size, add or change the LKIDLONGPOOLLEN modifier for
the volume that incurred the space allocation errors to increase the amount of
space available for lock tables.
5074: ZDSK-EVT-LNB-TABLE-USE
This message provides information on the use of active lock name space.
Token Description
ZEMS-TKN-EVENTNUMBER Event number for this message. Value is ZDSK-EVT-LAB-
TABLE-USE (5073).
ZEMS-TKN-LDEV Subject token that specifies the logical device number of
the affected disk drive.
ZDSK-TKN-POOL-SIZE Occurs four times and specifies, in this order, the number of
DP2 locks that can fit in the current space, the total space
required for the locks (in kilobytes), the number of locks in
use, and the space required by the in-use locks (in
kilobytes).
