Former Member

Hi

The current number of lock enteries is 8867. For our application requirement we have to increase the size to approx. 30000.

We would like to get answers of following questions,

1. What parameters should be changed?

2. What would be the impact on the system and it's performance when we increase the number of locks entries?

3. Any pre-requsite before making changes like buffer, memory etc?

Regards

Dharmendra

Hi,

The parameter "enque/table_size" governs the size of the Lock table in SAP system.

You can view the fill level of the lock tables using the statistics functions of lock management (transaction SM12 -> Extras ->Statistics).

The default value of this parameter is 4096 (4 MB) and this parameter can be extended upto 102,400 (100 MB).

Please set this parameter in the instance profile of your CI system.
