Recently,The oracle DB version was upgraded from 22.214.171.124 to 126.96.36.199.
Since then the backup started to take more than 24 hours – 48 hours duration and sometimes it hangs. DB Statistics and DB Checks were manually triggered at OS Level daily and even these takes long time.
Usually Backup used to complete within 4-5 hrs before upgrade.
It is impacting day to day transactions and BI chain process badly as Back up is not completing on time.
Kindly guide us to resolve the problem. Thank you.
