RMON ISSUE ON ORACLE

[Tajammul_Ahmed]

Hi,

We are using Oracle 9i Standard edition on HP-UNIX, as a backend to support HP Openview (Network Management software).

Also we are taking online backup for this database, We are using HP Openview Data Protector to take online backup, ( Our Backup server is on windows platform and Database is on UNIX).

We had configured successfully oracle online database to be back up, which was working fine from last 3 to 4 months, suddenly it’s not taking the backup ( online database backup fails), I did some level of troubleshooting but couldn’t find the Issues, then I escalated the same to HP, they say's its oracle problem.

Problem : Unable to take Online backup.

HP Solution: according to them it’s RMON problem, I’m not the oracle DBA so I don’t know how to verify RMON settings.

Also I’m unable to login as sysdba.

Here is the detail

Actual situation when backup was working fine.
#su oracle
#Sqlplus / nolog
Sql> connect /as sysdba.
Connected.

Present Situation
#su oracle
SQL> connect /as sysdba
ERROR:
ORA-01031: insufficient privileges

If I use below method it’s working fine.
SQL> connect oracle/oracle as sysdba;
Connected.
SQL>
I know this is some operating system user issue with oracle user, but I don’t know how to solve this.

Summary : I think we have to work on RMON, OS user and Oracle user.

If you need further Info please let me know I’ll provide you.

Your kind help will be highly appreciated to solve this Issue.

Thanks and best regards
Mohammed Tajammul Ahmed.

Hi Mohammed

Error message says everything, you cannot use parallelism with Standart Edition,

RMAN-03002: failure of allocate command at 11/21/2007 09:58:51
RMAN-06181: multiple channels require Enterprise Edition

RMAN> **end-of-file**


Oracle Reference

RMAN-06181 multiple channels require Enterprise Edition

Cause: Attempt to allocate more than one channel in a job.

Action: Remove all except one ALLOCATE CHANNEL command.


http://download.oracle.com/docs/cd/B10500_01/server.920/a96525/rmanus.htm

Apply the action and try again

Best Regards

hi,

I think the problem is related to the fact that you are running the Standard Edition of Oracle and trying to run RMAN with options for Enterprise Edition.

When checking the above extract, i can see:
"RMAN-06181: multiple channels require Enterprise Edition "


Try to modify your script so that it uses only one channel and see if it works!

revert!

kind regards

Dear All,

Thanks a lot for your reply, unfortunately I'm not the oracle DBA so I don't know how to apply

"Remove all except one ALLOCATE CHANNEL command"

Even I don't know how to modify the script.

I need your help to modify the script or send me the procedure.

Thank.

[Murat SULUHAN]

Hi

your rman script as follows

RMAN>
RMAN> run {
2> allocate channel 'dev_0' type 'sbt_tape'
3> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=openview,OB2BARLIST=ORACLE_DAI
LY_BACKUP,OB2BARHOSTNAME=tshpov1.tawasulservices.com)';
4> allocate channel 'dev_1' type 'sbt_tape'
5> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=openview,OB2BARLIST=ORACLE_DAI
LY_BACKUP,OB2BARHOSTNAME=tshpov1.tawasulservices.com)';
6> allocate channel 'dev_2' type 'sbt_tape'
7> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=openview,OB2BARLIST=ORACLE_DAI
LY_BACKUP,OB2BARHOSTNAME=tshpov1.tawasulservices.com)';
8> allocate channel 'dev_3' type 'sbt_tape'
9> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=openview,OB2BARLIST=ORACLE_DAI
LY_BACKUP,OB2BARHOSTNAME=tshpov1.tawasulservices.com)';
10> backup incremental level 0
11> format 'ORACLE_DAILY_BACKUP.dbf'
12> database;
13> sql 'alter system archive log current';
14> backup
15> format 'ORACLE_DAILY_BACKUP.dbf'
16> archivelog all;
17> backup
18> format 'ORACLE_DAILY_BACKUP.dbf'
19> current controlfile;
20> }


it must be like below, open your script in DP GUI and then delete allocate channel lines from rman script except first one.

RMAN>
RMAN> run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=openview,OB2BARLIST=ORACLE_DAI
LY_BACKUP,OB2BARHOSTNAME=tshpov1.tawasulservices.com)';
backup incremental level 0
format 'ORACLE_DAILY_BACKUP.dbf'
database;
sql 'alter system archive log current';
backup
format 'ORACLE_DAILY_BACKUP.dbf'
archivelog all;
backup
format 'ORACLE_DAILY_BACKUP.dbf'
current controlfile;
}
Save the script and backup session, then try again

hi,

Please do not forget to backup any scripts before making the changes.

Also verify if the performance you are getting is acceptable to your DBA. Otherwise you will have to review your stategies.


Good luck!
