Parameter
enque/table_size
Short text
Size of lock table
Parameter Description
This parameter defines the size of the lock table that is held in main memory by the enqueue server. The lock table contains information on which locks are currently held by whom.
The size of the lock table limits the maximum number of lock entries, the maximum number of elementary lock names, and the maximum number of lock owners.
In the case of an overflow of the lock table, you should check whether the update server is working correctly, since the lock table can grow in size very quickly if updates stop. If no update problems exist, you can use this parameter to increase the size of the lock table.
The Computing Center Management System (CCMS) monitors the status of the lock table constantly and outputs warnings if the space available is not adequate.
You can view the fill level of the lock tables using the statistics functions of lock management (transaction SM12 -> Extras -> Statistics).
