28 Deployment Guide
26 Perform the following steps on each node :
a Ty p e srvctl status database -d <database name> to determine which database
instance exists on that node.
b Type the following commands to add the ORACLE_SID environment variable entry in the
oracle user profile:
echo "export ORACLE_SID=racdbx" >> /home/oracle/.bash_profile
source /home/oracle/.bash_profile
where racdbx is the database instance identifier assigned to the node.
This example assumes that
racdb is the global database name that you defined in DBCA.
27 On one node , type:
srvctl status database -d dbname
where dbname is the global identifier name that you defined for the database in DBCA.
If the database instances are running, confirmation appears on the screen.
If the database instances are
not running, type:
srvctl start database -d dbname
where dbname is the global identifier name that you defined for the database in DBCA.
RAC Post Deployment Fixes and Patches
This section provides the required fixes and patch information for deploying Oracle RAC 10g.
Reconfiguring the CSS Miscount for Proper EMC PowerPath Failover
When an HBA, switch, or EMC Storage Processor (SP) failure occurs, the total PowerPath failover time
to an alternate device may exceed 105 seconds. The default CSS disk time-out for 10g R1 version 10.1.0.3 is
45 seconds. To ensure that the PowerPath failover procedure functions correctly, increase the CSS
time-out to 120 seconds.
To increase the CSS time-out:
1
Shutdown the database and CRS on all nodes except on one node.
2 On the running node, log in as user root and type:
/opt/oracle/product/10.1.0/crs_1/bin/crsctl set css misscount 120
3 Reboot all nodes for the CSS setting to take effect.
