Failed to create keys in the OLR, rc = 127, 32512

OLR configuration failed

해결 방법 : 

아래 패키지를 설치해 준다.

yum install -y libcap-2.16-5.5.el6.i686

yum install -y compat-libcap1-1.10-1.i686

yum install -y compat-libcap1-1.10-1.x86_64

그 후 root.sh를 다시 실행하기 전에 rootcrs.pl 스크립트를 사용하여 Grid를 deconfig 해야 한다.

rootcrs.pl 스크립트는 $GRID_HOME/install 에 있다. 

[root@oracle50 install]# pwd

/app/oracle/product/11.2.0/db_1/crs/install

[root@oracle50 install]# ./rootcrs.pl -deconfig -force -verbose

Using configuration parameter file: ./crsconfig_params

rootcrs.pl 스크립트가 완료되면 root.sh를 다시 실행하면 된다.

원인 : 

패키지가 제대로 설치되지 않아 발생하는 문제.
