ORA-00439 feature not enabled-Real Application Clusters solution error reported when the instance is started after the RAC Install patch

 

 

My friend said that after Windows RAC is patched, a node instance cannot be started and other processes are normal.

 

ORA-00439: feature not enabled: Real Application Clusters

 

I searched on Metalink for the Linux platform. The solution to the window platform was not found. However, my friend solved the problem and re-installed the patch on the problematic node. OK.

 

The cause of this error is that RAC does not link to RDBMS home.

 

 

You can perform the following steps to check whether RAC is linked to the RDBMS home.

(1) Enter $ ORACLE_HOME/rdbms/lib

(2) execute the following command:
Nm-r libknlopt. A | grep-C kcsm. o

 

If the returned value is equal to 0, there is no link;

If the returned value is greater than 0, it is already linked.

 

This is one of my test environments:

[Oracle @ Rac1 ~] $ CD $ ORACLE_HOME/rdbms/lib

[Oracle @ Rac1 lib] $ nm-r libknlopt. A | grep-C kcsm. o

1

 

 

Solution:

1. Disable all instances on the corresponding RDBMS home. Generally, it is one.

2. Enter $ ORACLE_HOME/rdbms/lib

3. users using Oracle relink:

Make-F ins_rdbms.mk rac_on ioracle

You can perform the following two steps:

Make-F ins_rdbms.mk rac_on

Make-F ins_rdbms.mk ioracle

4. Restart the instance

 

 

Note: The value of cluster_database, which is false may also cause this error.

 

SQL> alter system set cluster_database = true scope = spfile SID = '*';

System altered.
