Creating Database on Oracle Database 18cR1 using DBCA Gui and then Silent

Creating Database on Oracle Database 18cR1 using DBCA Gui & then Silent.

Sounds tricky?, yes it is bit tricky. To create Database in Oracle Database 18cR1, we’ll need to use both dbca utility GUI as well as Silent. However it would not take a long time here. We’ll going to do it very quickly. If you haven’t installed 18c yet you may follow this guide for step by step installation.

Let’s Start.


1. Check if your .bash_profile is pointing to Oracle Database 18c home, and then launch Installation Wizard by typing dbca on linux terminal.

DBCA 18cR1


  • Select Create a database and click NEXT.

DBCA 18cR1


  • Select Advanced configuration and click NEXT.

DBCA 18cR1


  • Select Oracle Single Instance database and select General Purpose or Transaction Processing and click NEXT.

DBCA 18cR1


  • Enter the name of your database and click NEXT.

DBCA 18cR1


  • Select Storage options and click NEXT.

DBCA 18cR1Note: Optionally you can also multiplex of logs and control files.


  • Here I’m using three way multiplexing. click Okay to proceed.

DBCA 18cR1


Oops! ORA-12754.DBCA 18cR1No prob chill, we have hack for this. let’s click on abort.


2. Now the silent mode comes into picture.

Before we proceed with silent, we’ll have to make one small change in a response file. We need to add one magic line 😛

DBCA 18cR1This is the line. Let’s add it.


  • Edit your saved response file using VI or any other text editor.
[[email protected] ~]$ vi dbca_DEMTEST.rsp
  • Go to Initialization Parameter section in your response file.
#-----------------------------------------------------------------------------
# Name : initParams
# Datatype : String
# Description : comma separated list of name=value pairs. Overrides initialization parameters defined in templates
# Default value : None
# Mandatory : NO
#-----------------------------------------------------------------------------
  • Add hidden parameter “_exadata_feature_on=true” in parameter file and then save and exit.
_initParams=undo_tablespace=UNDOTBS1,sga_target=1155MB,db_block_size=8192BYTES,nls_language=AMERICAN,dispatchers=(PROTOCOL=TCP) (SERVICE=DEMTESTXDB),diagnostic_dest={ORACLE_BASE},remote_login_passwordfile=EXCLUSIVE,db_create_file_dest=+DATA/{DB_UNIQUE_NAME}/,db_create_online_log_dest_3=/home/oracle/redo,db_create_online_log_dest_2=/u02/app/oracle/oradata,db_create_online_log_dest_1=/u01/app/oracle/oradata,audit_file_dest={ORACLE_BASE}/admin/{DB_UNIQUE_NAME}/adump,processes=300,pga_aggregate_target=385MB,nls_territory=AMERICA,local_listener=LISTENER_DEMTEST,db_recovery_file_dest_size=25500MB,open_cursors=300,log_archive_format=%t_%s_%r.dbf,compatible=18.0.0,db_name=DEMTEST,db_recovery_file_dest=+FRA,audit_trail=db,_exadata_feature_on=true

[ESC] > :wq > Enter (to save and exit)


  • Let’s now initiate DBCA in silent mode.
[[email protected] ~]$ dbca -silent -createDatabase -responseFile ./dbca_DEMTEST.rsp
Enter SYS user password:

Enter SYSTEM user password:
  • Enter password for SYS and SYSTEM users.

And here we go. it’s created now. Let’s invoke SQL*PLUS and check few things on newly created 18c Database.


SQL> select name,open_mode,host_name,version from v$database,v$instance;

NAME      OPEN_MODE            HOST_NAME                 VERSION
--------- -------------------- ------------------------- -----------------
DEMTEST   READ WRITE           dbnode1.demunix.com       18.0.0.0.0

As we can see, our database named DEMTEST is now been created on Oracle Database 18cR1.

 

Peace 🙂
