Upgrade , backup and restore

Filenet servers for Nestle were being upgraded on Saturday and Sunday , so my presence was required for emergency . I reached office at 1:30 pm on Saturday . Shyam told me that upgrade has failed and we will be rolling back . It was PE that failed to upgrade . I have yet to see the error which caused PE unable to connect to RDBMS .

Now i know that i will not be required as we have not changed anything in AE , still i had to be there till everything is completed and tested properly . So i waited while CE was being restored to previous version . After 4 hours we were informed that restoration has been done , so the support team checked CE but CE services were down .

So while the support and backup team were working on restoring CE , i watched Pirates of Caribbean 3 . Finally we were able to bring one node of CE up but i have already spent 27 hours in office without any sleep . We checked all scan stations and AE . Everything was up and working . i was pretty sure that now everything is fine so i decided to go .


so lesson learned from this was that while making backup make sure that it will work fine . and sometimes upgrade does not work

i enjoyed working at night , spending whole day without sleep . After many years i saw sun rising in the morning , birds flying and transition from night to day .
