Manually remove OLD DB HOMES if odacli-delete dbhome fails

Please follow the instructions below:

1. Check if any running jobs currently:

# odacli list-jobs.

2. If none, then stop the DCSAgents (initdcsagent) by running:

# systemctl stop initdcsagent

3. Manually remove the respective Oracle_Home folders using ‘rm -rf <DB_Home_Path>.

For example:

– As root:

rm -f /u01/app/odaorahome/oracle/product/12.2.0.1/dbhome_3

4. Then connect to the MySQL database repository and delete the corresponding DatabaseHome table in the repository.

(a) Navigate to the following directory

# cd /opt/oracle/dcs/mysql/bin

(b) Connect to the MySql database and use “dcsagentdb”

# /opt/oracle/dcs/mysql/bin/mysql –defaults-file=/opt/oracle/dcs/mysql/etc/mysqldb.cnf

mysql> use dcsagentdb;

(c) Find the DB id using the dbHomeLocation using the following command:

mysql> select id, name, dbHomeLocation from DatabaseHome where dbHomeLocation='<DB_Home>’ ;

(d) Locate the id then delete the DatabaseHome using the ID found from the above command

mysql> delete from DatabaseHome where id='<id_from_above_query>’;(Fill in the value of id located)

For example, (For the OraDB12201_home3 DBHome with the id value, ‘683daf6e-0a1e-45f0-9fce-75f059885bb6’):

mysql> delete from DatabaseHome where id=’683daf6e-0a1e-45f0-9fce-75f059885bb6′;

(e) Make sure the corresponding entry is deleted

mysql> select id, name, dbHomeLocation from DatabaseHome;

(f) Then commit the change and exit

mysql> commit;
mysql> exit;

Note: From 1 to 4 steps perform on both nodes

5. Start the DCSAgents (initdcsagent)

# systemctl start initdcsagent

6. Lastly, verify the dbhome is successfully deleted by running the following commands:

# odacli list-dbhomes
