this is a follow up from this question.
Let me start by saying that i am NOT a DBA, so i'm really really lost with this.
A few weeks ago, we lost contact with one of our SID'S. All the other services are working, but this one in particular is not.
What we got was this message when trying to connect
ORA-01033: ORACLE initialization or shutdown in progress
An attempt to
alter database open ended up in
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf'
I tried to shutdown / restart the database, but got this message.
Total System Global Area 566231040 bytes Fixed Size 1220604 bytes Variable Size 117440516 bytes Database Buffers 444596224 bytes Redo Buffers 2973696 bytes Database mounted. ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf'
When all continued the same, I erased the dbf files (rm xxx_data.dbf xxx_index.dbf), and recreated them using
I also tried to recreate the tablespaces using
`CREATE TABLESPACE DATA DATAFILE XXX_DATA.DBF`
Database not open
As I said, i don't know how bad this is, or how far i'm from gaining access to my database (well, to this SID at least, the others are working).
I would imagine that a last resource would be to throw everything away, and recreating it, but I don't know how to, and I was hoping there's a less destructive solution.
Any help will be greatly appreciated . Thanks in advance.
