Hi All,
Currently I have the compressed(.Z extension) online filesystem backup and trying to restore the backup through control file., I manually uncompressed and restored all the files in quality system and generate control file.
Now I am facing the error while running control file -
ORACLE instance started.

Variable Size 348127424 bytes

CREATE CONTROLFILE REUSE SET DATABASE "XXX" RESETLOGS NOARCHIVELOG

ALTER DATABASE OPEN RESETLOGS
*
ERROR at line 1:
ORA-01507: database not mounted
Can you please suggest is there any other method to uncompressed the datafiles.
