hi all, i am facing some server level issue one of our Database Production server. Actually we have 16 GB RAM with 4 processors for database server. among this we have enabled 12 GB for SQL Server Max memory.at this point of time server cpu utilization is reaching to 100% , due to this application is getting hanged.now recently we have upgraded our RAM from 16 GB to 32 Gb and we have configured 22 GB for SQL Server and remaining for O/S.Still we are facing the problem with CPU utilization and again its reaching to 100%. here my doubt is : whether this 32 GB RAM will utilize perfectly or we need to do some changes in boot.ini file. i have idea on SQL Server 2000 we can enable that AWE / PAE to make use of the RAM perfectly in 32-bit O/S and 32 bit SQL Server. but i am new to this 64 bit environment. current configuration settings: name minimum maximum config_value run_value max server memory (MB) 16 2147483647 22528 22528 Could anyone help me on this to resolve this issue... Thanks in advance, Thulasi.
