Performance Issues in SQL Server

Hi All,

I am facing issues in Production Server where DB Release is 10.50.1702 and DB is SQL Server.

I can see in the Tcode DB02 in the Alert Monitor Tree -->>Performance tab-->>Cache-->>page life expectancy which is 27 Secs< 300 Secs page life

                                                                                                                  Cache-->>Data Hit Ratio-->>84% < 90% data hit cache ratio

Please find the attachment contains the Error happened in the Production Server.Please help me out to resolve the issue as soon as possible.

Thanks
