Plan the appstier backup on timely basis.
If in your environment regular changes will run like .rdf or .fmb or OAF deployments you need to plan daily apps file system backup
If no much changes on day to day basis ,plan the backup accordingly amy be weekly or monthly
In Last month we have faced similar issue with Storage where we are using NFS , autoconfig will take huge time and it will error out
Autoconfig not able to execute any script even i cant able to connect sqlplus in application server
In OS logs i can see NFS server timeouts.
Later we changed file system from NFS to SAN, all issues resolved .
Thanks Shaik and ALL,
So I will recommend to the management to use storage systems like SAN, or NAS or DAS .
Are these storage need to be RAID configured? Or they are already in RAID by default?
What is the recommend RAID level for best performance? is it 0,1,2,3,4,5 etc?
It depends completely on the company SLA and investment.
If you can afford, you can go for Level 1. Use ASM for database. Connect and discuss with your Storage Admin/OS Admin who controls the Storage and discuss the recommendations and possibilities based on the Storage you have and what RAID is achievable.
