Today while deconfiguring one failed node from the clusterware I faced some Perl related issues that blocked me to run ./rootcrs.pl command. After installing few required packages I was able to deconfigure the node. Check the steps and let me know if it helped you and if you had different errors
[root@oratest02 install]$ ./rootcrs.pl -deconfig -force -verbose
-bash: ./rootcrs.pl: /usr/bin/perl: bad interpreter: No such file or directory
I checked for perl and didn’t find it.
If the perl wasn’t installed by default, install it:
[root@oratest02 install]$ which perl
/usr/bin/which: no perl in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/oracle/.local/bin:/home/oracle/bin:/home/oracle/.local/bin:/home/oracle/bin:/u01/app/12.2.0.1/grid/bin)
If the perl wasn’t installed by default, install it:
[root@oratest02 install]# yum install perl -y
Then I got the following errors and installed the required perl modules as follows:
[root@oratest02 install]$ ./rootcrs.pl -deconfig -force -verbose

Finally I was able to run rootcrs.pl and deconfigure the node from the clusterware
