During an install of Oracle 12cR1 RAC Grid Infrastructure on Red Hat or CentOS 6.2, 6.3 or 6.4, you run the runcluvfy.sh script to test node readiness and it fails with the following error:
ERROR: Reference data is not available for verifying prerequisites on this operating system distribution Verification cannot proceed
This is due to bug 15973656 which states that runcluvfy.sh cannot properly detect the Red Hat 6.2 and above operating system. The problem also affects CentOS 6.2 and above.
MOS provides a bug patch for this problem – clupack.zip. This zip file contains the following files:
- redhat-release-6Server-1.noarch.rpm
- filegroup6.jar
- filegroup10.jar
- cvu_prereq.xml
In fact Oracle half fixed this problem in 12cR1. You only need the RPM file. The RPM file is a dummy, which is needed because runcluvfy.sh “expects “6Server” to be returned. In Redhat 6.2 redhat-release-server rpm does not exist.”
So if you want to run runcluvfy.sh during a 12c RAC install, download the clupack.zip from bug 15973656 and load the RPM:
[root@ruggero clufix]# rpm -ivh redhat-release-6Server-1.noarch.rpm Preparing... ########################################### [100%] 1:redhat-release
Now runcluvfy.sh will succeed:
