Restartthe Enterprise Server.
▼Toset the keypoint interval
Keypointoperations compress the transaction log le. The keypoint interval is the number of
transactionsbetween keypoint operations on the log. Keypoint operations can reduce the size of
thetransaction log les. A larger number of keypoint intervals (for example, 2048) results in
largertransaction log les, but fewer keypoint operations, and potentially better performance.
Asmaller keypoint interval (for example, 256) results in smaller log les but slightly reduced
performancedue to the greater frequency of keypoint operations.
