Change Archivelog mode and Destination

Step 1: Check Archive log mode Status

Check current archive log mode status in oracle 19c.

SQL> archive log list

Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 2
Current log sequence 4

As we checked our database running in no archive mode.

Step 2: Create the Archive destination

Create a destination for archives.

$ mkdir -p /u01/archives

Step 3: Check the current Archive location

SQL> SHOW PARAMETER DB_RECOVERY_FILE_DEST

NAME TYPE VALUE
-------------------------- 	-----------  ----------------------------------
db_recovery_file_dest 		string       /u01/app/oracle/fast_recovery_area
db_recovery_file_dest_size 	big integer  8256M

Step 4: Change the log_archive_dest parameter

Try to change the log_archive_dest parameter value, but this time you will fail.

SQL> ALTER SYSTEM SET log_archive_dest ='/u01/archives' scope=both;
ALTER SYSTEM SET log_archive_dest ='/u01/ARC_BKP' scope=both
*
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16018: cannot use LOG_ARCHIVE_DEST with LOG_ARCHIVE_DEST_n or
DB_RECOVERY_FILE_DEST

Before you change the log_archive_dest location you should change the first DB_RERCOVERY_FILE_DEST and then update the log_archive_dest location.

SQL> alter system set DB_RECOVERY_FILE_DEST=”;

System altered.

Step 5: Change Archive Destination

Now change the archive destination, and you will succeed.

SQL> alter system set log_archive_dest='/u01/archives';

System altered.

Step 6: Change database archive log mode.

Here is the step to Change Archivelog mode and Destination.

SQL> alter database close;

Database altered.

SQL> alter database archivelog;

Database altered.

Now take bounce the database once and then check archive mode and its destination.

SQL> shut immediate
SQL> startup

SQL> archive log list

Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/archives
Oldest online log sequence 6
Next log sequence to archive 8
Current log sequence 8
