Oracle Database Design Using DBCA: Step 8 of 12
In this step select the “Specify Flash Recovery Area” in case it's
not already selected. The DBCA wizard also provides you the
option to check “Enable Archiving” in case you want to run the
database in ARCHIVELOG mode. You can run Oracle Server in
ARCHIVELOG Mode or NOARCHIVELOG Mode. In the
archive log mode, the Redo Log files will get archived before
they get over written by LGWR (log writer process). In
NOARCHIVELOG mode once Redo Log files get filled up,
Oracle will start overwriting them. The Redo Log files get
utilized in a circular fashion.
By default it's no archiving mode. If you select the archiving
mode then all you have to specify is the destination or the path
and location of folder where you want to place the archived
Redo Log files.
Make sure “Enable Archiving” is unchecked and finally click the
“Next” button. This action will run our database in
NOARCHIVELOG mode. Later in the topic we will learn how
to put the database back in ARCHIVELOG mode.
