SVR4 Error?

[midora]

RMAN-06403: could not obtain a fully authorized session
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
SVR4 Error: 2: No such file or directory

when the backup trying to backup it gives this error in log?

why?

Thanks

a) You did not set the ORACLE_HOME/ORACLE_SID

b) The database is not started

[midora]

oracle_home/oracle_sid is set in the script of backup and when i do ps -ef|grep datatabase it does return records so that means database is running? please let me know if there is other way to check it.

OS: sun solaris:
Oracle 10.1.0.3.0

Restart DB if required. this may solve the problem...

hot backup is fine but not think controlfile backup is having problem!! please guide!!

[LKBrwn_DBA]

Is this the first time you try and execute this script?

--- DELETED ---

Ooops, the typo I found is actually generated by the forum...

[midora]

no it's been running since long and just started show error in email like follow:
RMAN-06403: could not obtain a fully authorized session
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
SVR4 Error: 2: No such file or directory

Long shot: check if your Oracle home mount point is 100% full.
