ULC Efficiency tab

ULC Efficiency tab*

This User Log Cache Efficiency graph shows the percent of the time that the User Log Cache was flushed because it was full.

A high percentage indicates that Adaptive Server is flushing the ULCs more than once per transaction, negating some performance benefits of user log caches. If the value is greater than 20%, consider increasing the size of the user log cache size parameter.

Increasing the ULC size increases the amount of memory required for each user connection, so you do not want to configure the ULC size to suit a small percentage of large transactions.

*Available only for Adaptive Server versions 12.5.0.3 or later
