Oracle Database not started via srvctl with error CRS-2674, ORA-01034 if you installed Grid infrastructure with different user

by Vazha Mantua 28. November 2011 15:59

if you try start database(version 11R2) with srvctl you should got error:


We got this case, when we created database with Database scripts in postDBCreation.sql


PRCR-1079 : Failed to start resource ora.test.db

CRS-5011: Check of resource "TEST" failed: details at "(:CLSN00007:)" in "/u0/app/grid/product/11.2.0/log/testmachine/agent/ohasd/oraagent_grid/oraagent_grid.log"

CRS-2674: Start of 'ora.test.db' on 'testmachine' failed

ORA-01034: ORACLE not available

ORA-27101: shared memory realm does not exist

Linux-x86_64 Error: 2: No such file or directory

Process ID: 0

Session ID: 0 Serial number: 0


Cause of this error is that grid agent is running with difference user. During the instance startup using srvctl, agent tries to modify the files under $ORACLE_HOME/dbs and $ORACLE_HOME/srvm/admin,

But Unfortunately Grid user doesn't have write permissions to these directories, startup could fail.


You can add permission to write on directories for Grid user with commands:

chmod 775 /u0/app/oracle/product/11.2.0/dbs

chmod 775 /u0/app/oracle/product/11.2.0/srvm/admin

ORA-15027: active use of diskgroup precludes its dismount

by Vazha Mantua 24. November 2011 22:33

Good Day,

Today We discuss about Error:ORA-15027: active use of diskgroup precludes its dismount.This error occurred  we I tried to  drop disk group on ASM instance (version 11GR2).

Cause of this error is that ASM spfile is located on Diskgroup


In that case you need to create a pfile from the spfile and then startup the ASM instance using the pfile.

1.Find location of AMS spfile with command SQL> show parameter spfile

2.Create pfile from spfile

3.Start ASM instance with pfile, for Example SQL> startup pfile=$ORACLE_HOME/dbs/init+ASM.ora

4.Drop Diskgroup

Good Luck!


ORA-27029: skgfrtrv: sbtrestore returned error

by Vazha Mantua 16. November 2011 13:43

Good Day All,

Today We observe a main error, which appear when you are trying restore database to new location via Veritas Netbackup soft


When you tried restore for example your controlfile from autobackup which is stored on types, you got a error

ORA-27029: skgfrtrv: sbtrestore returned error




With NetBackup on UNIX one can restore a database to a client other than the one that originally performed the backup. Symantec refers to this process as an 'alternate client restore' while Informix refers to this same process as an 'imported restore.By default configuration there is some restrictions for restoring to new server.


1.Remove restrictions for alternate client restores for all clients

Create the following f file /usr/openv/netbackup/db/altnames/No.Restrictions on the master server

2.Restrict the restore to / from certain clients

Create the following file on the NetBackup master server: /usr/openv/netbackup/db/altnames/<target_client_name>
where "<target_client_name>" is the name of the client that will receive the restore. This will allow this client to restore images from any other client.
