Hi, I am monitoring a sql Server database cluster. I have found the average Page life expectancy to be 10.4 minutes and the maximum value was 267.4 hours. I have monitored over 24000 one minute intervals and from these 65% occured at less then 300 seconds (5min). What does this indicate for the state of my SQL Server? For these intervals where the page life expectancy goes below 300 seconds the batch request per sec happens to be low at approximately 44 per second. From the above, I think that my SQL Server 2000 needs more memory - this would be difficult as server is windows 2003 (4gb memory of which 2gb to the operating system) Is there any advise or explanation as to what is going on?
