locksiz

Maximum size of shared memory for locks.

Synopsis

[config]    locksiz=n

Description

Size (in bytes) of memory allocated for locks. The system rounds up the value to the next multiple of 64 kilobytes. The default is 16777216 bytes. (On the IBM AIX and HP-UX platforms, the default is 33554432 bytes.) The range is 65536 bytes up to the size. If you need more room for the lock table, increase the parameter as well. If you edit this setting, changes will take effect immediately.
Examples
locksiz=786432
locksiz=1179648
Range of Values
65536 bytes up to the size of . Since memory used to allocate locks is taken from (the Generic Memory Heap), you cannot use more memory for locks than exists in . Memory from
gmheap
is also used for NLS tables and the PID table. If you increase the size of
locksiz
, increase the size of as well.
On all platforms, except for AIX and HP-UX, the default amount of memory allocated for locks (the maximum size of the lock table) is 16777216 bytes. On the AIX and HP-UX platforms, the default amount of memory allocated for locks is two times the default on other platforms; that is 2 * 16777216 (33554432) bytes.
Management Portal
