10g Release 1 Instructions

Oracle Database Tips by Donald Burleson

To begin, switch to the root user and change directories to $ORA_CRS_HOME/install. Run the script as shown in Figure G.1. It may appear to hang at a message that reads in part ?Aborted? but allow it a couple of minutes to complete. This script should be run from each node. 

Next, run the script as shown in Figure G.2. Allow this script to finish on one node before beginning it on the next.

If you still have a copy of the old Oracle 9i srvconfig file, you may optionally choose to use its configuration as a starting point. To do so, follow the steps in Figure G.3. The dd command, which requires a few minutes to complete, should be run from only one node.

At this point, run $ORA_CRS_HOME/root.shfrom each node. Next, run $ORACLE_HOME/ from each node. Finally, run the 10g version of netca, as oracle, to re-register the listeners with CRS.

10g Release 2 Instructions

For 10g Release 2, the instructions are similar, but be careful. Do not run the scripts $ORA_CRS_HOME/install/ first and then $ORA_CRS_HOME/install/ second, as was done for Release 1. These scripts cause a problem for vipca.

They make it so that vipca cannot create a new vip, gsd, and ons! Figure G.4 shows the error I have experienced both on the command line and as seen through the vipca tool. The only fix I have found for this error is to revert to an image of Release 1 software, then to reinstall Release 2.

To rebuild the 10g Release 2 CRS, run the following scripts. Each script must be completed on each node before continuing to the next script.

$db10g1/          ### will launch vipca on first node
gedit /etc/oratab        ### fix the entry for * to 10g-R2 home
$db10g2/bin/netca        ### run as the oracle user, not root

Clearly, this is a hack (the files in the release1 directory were copied from the previous release). Although it works, it is doubtful that Oracle Support would agree with it.
