I got below error when I ran “./rootcrs.pl –patch” as a last command
[root@Server1 ~]# cd /usr/grid_app/oracle/product/11.2/grid/crs/install
[root@Server1 install]# ./rootcrs.pl -patch
Using configuration parameter file: ./crsconfig_params
Undefined subroutine &main::read_file called at crspatch.pm line 86.
Followed roothas.pl -patch or rootcrs.pl -patch Fails with ‘Undefined subroutine’ (Doc ID 1268390.1)
2] Take a backup of the file /crs/install/crsconfig_lib.pm
# cd /crs/install
# cp crsconfig_lib.pm crsconfig_lib.pm.bak
Make the following change in that file crsconfig_lib.pm
From
my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR
To
my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR read_file
Now try with
roothas.pl -patch
or
rootcrs.pl -patch
