Solution:

Step 1) verify the environment

[root@ORA_SRVR ~]# env |grep ORA
ORACLE_SID=+ASM
ORACLE_BASE=/u00/app/oracle
ORACLE_HOME=/u00/grid/oracle/product/19c/grid
[root@ORA_SRVR ~]#

 

Step 2) change directory to /u00/grid/oracle/product/19c/grid/crs/install

root@ORA_SRVR ~]# cd $ORACLE_HOME
[root@ORA_SRVR grid]# cd crs
[root@ORA_SRVR crs]# cd install/[root@ORA_SRVR install]# pwd
/u00/grid/oracle/product/19c/grid/crs/install

 

Step 3) run ./roothas.sh -unlock from install directory

[root@ORA_SRVR install]# ./roothas.sh -unlock
Using configuration parameter file: /u00/grid/oracle/product/19c/grid/crs/install/crsconfig_params
The log of current session can be found at:
/u00/app/oracle/crsdata/ORA_SRVR/crsconfig/haunlock__2022-06-13_01-35-18PM.log

[root@ORA_SRVR install]# mv $ORACLE_HOME/rdbms/lib/config.o $ORACLE_HOME/rdbms/lib/config.o_BKP

 

Step 5) Run rootadd_rdbms.sh script

[root@ORA_SRVR install]# $ORACLE_HOME/rdbms/install/rootadd_rdbms.sh

 

Step 6) run ./roothas.sh -postpatch

[root@ORA_SRVR install]# ./roothas.sh -postpatch
