Lock list escalations: <count>

Explanation

The number of Structure linkrow locks in a table is too high. The database system attempts to convert the row locks into a table lock (see also Structure linkLock Behavior).

User Response

You can specify the maximum possible number of row locks in the lock list in the database parameter Structure linkMAXLOCKS. The database system attempts to convert the row lock into a table lock if a Structure linktask holds more than 0,1*MAXLOCKS row locks in a table. If too many escalations occur, increase the parameter value.

Whether escalations are a problem depends strongly on the application in question. If escalations occur, check the application to see whether modifying transactions that lock a lot of rows cannot be corrected by an interim Structure linkCOMMIT.
