There are three nodes C1, c2, c3 in an Oracle 10g R2 RAC environment

However, due to a misoperation, the OCR is destroyed, and the disk backup only has the status of C1 and c2 nodes. Restore the OCR disk, so C3 will be lost.

The following problems were found in the process of adding c3 back to the cluster:

In the case of .addNode, there will be c3 still in the runInstaller graphical interface, making it impossible to join.

Corresponding method:

1. Find / u01/app/oracle/oraInventory/ContentsXML/inventory.xml

Remove the c3 node information.

2. Find / u01/app/oracle/product/10.2.0/db_1/inventory/ContentsXML/oraclehomeproperties.xml

Remove the c3 node information (that is, in $ORACLE_HOME)

3. Find / u01/crs_1/inventory/ContentsXML/oraclehomeproperties.xml

Remove the c3 node information (that is, in $CRS_HOME)

This can be done with addNode, and the rest is no different from a normal join node, except that there will be some warnings that some files already exist.
