To set the keypoint interval
Keypoint operations compress the transaction log le. The keypoint interval is the number of
transactions between keypoint operations on the log. Keypoint operations can reduce the size of
the transaction log les. A larger number of keypoint intervals (for example, 2048) results in
larger transaction log les, but fewer keypoint operations, and potentially better performance.
A smaller keypoint interval (for example, 256) results in smaller log les but slightly reduced
performance due to the greater frequency of keypoint operations.
In the tree component select the Congurations node.
Select the instance to congure:
To congure a particular instance, select the instance’s cong node. For example, the default
instance, server , select the server-config node.
To congure the default settings for all instances, select the default-config node.
Select the Transaction Service node.
Enter the number of transactions between keypoint operations in the Keypoint Interval eld.
The default value is 2048.
Click Save.
Restart the Enterprise Server.
