How to enable archivelog mode using DBCA

When we create a database using dbca silent option, by default the database is created in noarchivelog mode. So to enable archiving, one will have to shutdown, mount, enable archivelog and then open the database.

Normally we’ll use following command line to create a database using dbca

$ dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName ORCL -sid ORCL -SysPassword oracle -SystemPassword oracle -emConfiguration NONE -storageType ASM -asmSysPassword oracle -diskGroupName DG8

Here we use a readymade template General_Purpose.dbc, which is shipped by oracle along with it’s install binaries. So the trick is to create a new template using existing one, but enable the archiving.

Following are the steps, one need to follow to create a new template

Select Manage Template option

Select Create a Database Template, from an existing template

Select General Purpose Template

Specify new template name (Here I’ve entered mytemplate)

Select Use database File Locations from template

This is the most important screen, in creating the template. Here we’ll specify to enable archiving and Flash Recovery Area

Specify the memory parameters

Verify the file locations and click next

Check the parameters, options and click next

Template Creation is in progress (dbca will create files in $ORACLE_HOME/assistants/dbca/templates)

$ cd $ORACLE_HOME/assistants/dbca/templates
$ ls -al | grep my

-rw-r—– 1 ora11 oinstall 5405 May 7 18:24 mytemplate.dbc (database configuration XML)
-rw-r—– 1 ora11 oinstall 187441152 May 7 18:24 mytemplate.dfb (data file backup)

Template creation finished.

Now create the database using new template

$ dbca -silent -createDatabase -templateName mytemplate.dbc -gdbName ORCL -sid ORCL -SysPassword oracle -SystemPassword oracle -emConfiguration NONE -storageType ASM -asmSysPassword oracle -diskGroupName DG8 -recoveryGroupName DG1

    But what in the template sets the archivelog to be on? You don’t show what actually turns it on?
