Notice 
This section explains the points you need to pay close attention to. 
● 
The Oracle database needs to be allocated to the shared disk. 
 
● 
PRIMECLUSTER operated with Oracle products of different versions is not supported.   
For the supported Oracle products, refer to the installation guide or handbook. 
 
● 
A user name, user ID, group name, and group ID should be identical on all nodes to install 
Oracle. 
 
● 
A different user name should be assigned respectively to create multiple ORACLE_HOME 
in one server. 
 
● 
To monitor the Oracle instance, the detector is connected to the database by using system 
user.    The detector also checks Oracle operation by using the system user’s default 
tablespace. 
   
● 
The Oracle instance fails to stop in the “immediate” mode in the following situations: 
 
1.  DBA user is connected to the Oracle instance, or 
2.  The Oracle instance backup is in progress 
   
● 
If the Oracle instance is stopped in the “abort” mode, automatic recovery runs when the 
Oracle instance is restarted next time. 
 
● 
The Oracle resource needs to be allocated to the shared disk as prerequisite.    The 
Oracle archive log files might be stored on the local disks.    In such a case, if recovery is 
required, the files from all nodes should be put together on the node where Oracle is 
recovered. 
   
● 
Startup and stop time of the Oracle instance varies depending on the database size.    The 
default timeout duration of the Oracle instance startup is 10 minutes.    The default timeout 
duration of the Oracle instance stop is 5 minutes. 
   
● 
Be aware of the exit code and timeout duration when the following scripts are set up: 
PreOnlineScript, PostOnlineScript, PreOfflineScript, PostOfflineScript, FaultScript 
 
● 
When a database failure is detected during Oracle instance startup, recovery operation is 
automatically run.    This is not applicable to Oracle9iRAC.    If recovery is required, the file 
names in the “/opt/FJSVclora/usr” directory should be replaced as follows: 
 mount10EndBackup.sh 
<--> 
_mount10EndBackup.sh 
 mount20MediaRecover.sh 
<--> 
_mount20MediaRecover.sh
