HI Xenthil,

Unfortunately the PLE is not a value that can be changed. The only way to get the PLE higher is to find the memory condition that is causing you to run out of memory. In most cases, it is missing indexes. When you are missing indexes, then table scans read in every row and cause memory issues. Try the following DMV to find the missing indexes:

Usually if you get the top 5 – 10, you will see a dramatic increase.

Good Luck!
Derek
