Install Oracle Database 18c In Silent Mode Part2

Written By Srikrishna Murthy Annam on Saturday, September 8, 2018 | 8:50 PM

In this post, we will discuss about the creation of Oracle Database 18c in silent mode. I wrote another post with detailed steps to install Oracle Database 18c in silent mode Install Oracle Database 18c In Silent Mode.

For steps to install Database 18c refer my other posts Oracle Database 18c Simple Installation and Install Oracle Database 18c In Silent Mode. For complete deinstallation of the Oracle Database 18c refer my other post Deinstall/Uninstall Oracle Database 18c.

For this post, we assume that the Oracle Database 18c rdbms binaries are already installed. To install Oracle Database 18c, set the environment variable and then start database creation using dbca.

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/18.0.0/dbhome_1

$ORACLE_HOME/bin/dbca -silent -createDatabase -gdbName db18c -sid db18c  -templateName General_Purpose.dbc -sysPassword welcome1 -systemPassword welcome1 -emConfiguration DBEXPRESS -dbsnmpPassword welcome1 -listeners LISTENER -createAsContainerDatabase false –ignorePreReqs


The complete session log for Database installation is ….


[oracle@askm18c dbhome_1]$ $ORACLE_HOME/bin/dbca -silent -createDatabase -gdbName db18c -sid db18c  -templateName General_Purpose.dbc -sysPassword welcome1 -systemPassword welcome1 -emConfiguration DBEXPRESS -dbsnmpPassword welcome1 -listeners LISTENER -createAsContainerDatabase false -ignorePreReqs

Verify the database creation using the following steps …..


SQL> select name,user,cdb from v$database;

NAME      USER            CDB
--------- --------------- ---
DB18C     SYS             NO

SQL> select name,user,created,cdb from v$database;

NAME      USER            CREATED   CDB
--------- --------------- --------- ---
DB18C     SYS             16-AUG-18 NO

SQL> select instance_name,status from v$instance;

INSTANCE_NAME    STATUS
---------------- ------------
db18c            OPEN

SQL> select file_name from dba_data_files;

FILE_NAME
----------------------------------------------
/u01/app/oracle/oradata/DB18C/users01.dbf
/u01/app/oracle/oradata/DB18C/undotbs01.dbf
/u01/app/oracle/oradata/DB18C/system01.dbf
/u01/app/oracle/oradata/DB18C/sysaux01.dbf



Following syntax helps to delete the database using dbca.


[oracle@askm18c dbhome_1]$ $ORACLE_HOME/bin/dbca -silent -deleteDatabase -sourceDB db18c -sysDBAUserName sys
Enter SYSDBA user password:
