How to Create Service on Non-RAC PDB

As we know, we can use ‘srvctl’ utility to create a service for a RAC database. Now I demonstrate how to create a service for a standalone CDB/PDB database.

For non CDB/PDB database, we can use ‘service_name’ parameter to specify service names.

SQL> show parameter service_name;

 NAME             TYPE    VALUE
 --------------- ------- ------------------
 service_names   string  HR,STOCK,INVENTORY

How to Rename CDB PDB and Change DBID in Oracle Multitenant Architecture

Sometimes DBAs have to change CDB/PDB names to meet the organization’s naming standards, and change the DBID of a cloned database to make sure database registered in RMAN recovery catalog.

This post illustrates how to rename CDB/PDB, change DBID, and move and rename datafiles/tempfiles/controlfiles of CDB/PDB.

Create 12.2.0.1 Multitenant Database with DBCA

Here is an example of how to create a multitenant oracle database with DBCA in Oracle 12.2.0.1.

We will create a multitenant database with 1 CDB and 1 PDB. For CDB, all the components are selected and installed.  But for PDB, only following three components are selected and installed :

Oracle JVM 
Oracle Text
Oracle Multimedia

1)Startup VNCSERVER on node 1.

[oracle@racnode1 ~]$ vncserver :1

New 'racnode1.virtuallab:1 (oracle)' desktop is racnode1.virtuallab:1

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/racnode1.virtuallab:1.log

[oracle@racnode1 ~]$

2) Open VNC Viewer .

3) Startup DBCA.

[oracle@racnode1 ~]$/u01/app/oracle/product/12.2.0/dbhome_1/dbca
dbca Create a database
dbca Create a database

4) Choose “Create a database”
“Advanced configuration”
“Custom database”
“Select all” nodes
Put in Database Name, SID, PDB details.

5) check the database.
