No Backup !!! Think Again

While I was drinking my coffee yesterday in the office, A Customer Called me complaining that Non Production Database Is not working and Database Administrator quit his job without any Handover the situation was so creepy, This database hold Fusion middleware Repository and configuration, The development team use it before deploy anything on Production Database ( No Backup configured !!!! ),  

Trying to Recover Database and Open it with Resetlogs will lead to this error :-

ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/u01/app/oracle/oradata/NPDB/system01.dbf'

This Error is only apart of the problem, To solve it :-

Recover database using file name (Redolog) to get the current filename :-

SQL > Startup mount ; SQL > select member from v$logfile lf , v$log l where l.status='CURRENT' and lf.group#=l.group#;
 MEMBER

To Configure PHP with Oracle OHS Follow the below steps :-

Step #1:-

export ORACLE_HOME=/Siebel/ohs/Middleware/Oracle_WT1/
export ORACLE_INSTANCE=/Siebel/ohs/Middleware/Oracle_WT1/instances/instance1/
