VIPCA - NO INTERFACE AVAILABLE(NATIVE:listNetInterfaces:[11])

While doing the RAC install, after running the root.sh file on both the nodes and while running the vipca manually we may encounter the following error.

ERROR:

Error: No interface available(Native: listNetInterfaces:[11])

SOLUTION:

Solution: On both the hosts you should able to do "nslookup" on vipname. For example if your vip name is configured in /etc/hosts file as below. # Public VIPs for RAC 1.2.3.4   node1-vip.sss.com    node1-vip 1.2.4.3   node2-vip.sss.com    node2-vip You should able to do "nslookup node1-vip.sss.com". If you get "nslookup" not found, you have to contact your network adminstrator to configure "nslookup" on these hosts.

CRS ERROR - PRKC-1073 - Error while copying directory /opt/mis/oracle/product/crs10 with exclude file list 'null'

We may encounter the following error while installing the CRS. The error is as follows.

ERROR:

Error:Error while copying directory "/opt/mis/oracle/product/crs10/" with exclude file list "null" to nodes node2. [PRKC-1073:Failed to transfer directory "/opt/mis/oracle/product/crs10/" to any if the given nodes "node2". Error on node node2:mkdir:/opt/mis/oracle/product/crs10": Exists but it is not a directory:failed]

CAUSE:

Cause: 1) The possible cause for this error is, the directory "crs10" in the path "/opt/mis/oracle/product/crs10/" is not a directory. If we create crs10 as a symbolic link to some other location, the CRS installation will fail. What I have observed was it will install all the files in "node1", but it will not copy the install files on node2. 2) The other reason will be this directory should have the correct ownership for the files in this directory.

SOLUTION:

Solution: 1)The folder where we are installing the CRS software should not be a symbolic link. 2)Change the ownership of the directory using the following command. chown -R oracle:dba /opt/mis/oracle/product/crs10/
