Dear All,
Today one of my app team person had come up with a concern. His application and SQL server both are running on same server. And they have assigned 75% percent of memory to SQL server and remaing is for OS. Now a days he is receivng some windows alerts regarding to memory 'Memory usage reached to critical'. So they are looking to reduce the assigned memory size of SQL server(75%). So if they reduced same, the OS/App can use the same. We suggested them that SQL need 75% of physical memory but still they want to reduce the same. I have collected permon counters output and found that everthying was looking good. Please clarify me on below questions.
How can we check whether assigned 'Max server memory' for SQL server is using properly or not?
Assigning 75% of Physical memory to SQL server is correct?
Is that the best practice to maintain application and Database on same server?
What is the SQL Server: Buffer Manager:Page Life Expectancy counters recommended value.?(In our server the value is almost all times above than 109429) so is this a good sign?
Need your help to get rid from concerns and also to increase my skillset.
Thanks in advance,
Nagesh
