How to Create Database on ACFS

Assuming that you have created a ACFS file system for the database creation. Then you can go on reading this post.

Create a Database on ACFS

First of all, make sure everything is ready including ACFS mount point which is /u02/oradata1 in this case.

[grid@primary01 ~]$ crsctl status resource ora.data.oradata1.acfs -t
--------------------------------------------------------------------------------
Name           Target  State        Server                   State details
--------------------------------------------------------------------------------
Local Resources
--------------------------------------------------------------------------------
ora.data.oradata1.acfs
               ONLINE  ONLINE       primary01                mounted on /u02/orad
                                                             ata1,STABLE
               ONLINE  ONLINE       primary02                mounted on /u02/orad
                                                             ata1,STABLE
--------------------------------------------------------------------------------

Check the permission of the ACFS directory.

[oracle@primary01 ~]$ ll /u02/
total 32
drwxr-xr-x 4 oracle oinstall 32768 Dec  6 13:45 oradata1

Call DBCA to initialize a database.

After installation, we can check the status of listener and database.

[oracle@primary01 ~]$ lsnrctl status
...
Services Summary...
Service "+APX" has 1 instance(s).
  Instance "+APX1", status READY, has 1 handler(s) for this service...
Service "+ASM" has 1 instance(s).
  Instance "+ASM1", status READY, has 1 handler(s) for this service...
Service "+ASM_DATA" has 1 instance(s).
  Instance "+ASM1", status READY, has 1 handler(s) for this service...
Service "+ASM_FRA" has 1 instance(s).

Service "PRIMDBXDB" has 1 instance(s).
  Instance "PRIMDB1", status READY, has 1 handler(s) for this service...
The command completed successfully

Let’s see the configuration status of the newly created database.

[oracle@primary01 ~]$ srvctl config database -d primdb
Database unique name: PRIMDB
Database name: PRIMDB
Oracle home: /u01/app/oracle/product/18.0.0/db_1

Database is administrator managed

Check the running status of both nodes.

[oracle@primary01 ~]$ srvctl status database -d primdb
Instance PRIMDB1 is running on node primary01
Instance PRIMDB2 is running on node primary02

[oracle@primary01 ~]$ sqlplus / as sysdba
...
SQL> select instance_name from gv$instance;

INSTANCE_NAME
----------------
PRIMDB1
PRIMDB2

The list of data files look like that it’s a normal file system.

[oracle@primary01 ~]$ ll /u02/oradata1/DATA/PRIMDB/
