How to change database from Noarchivelog mode to Archivelog mode.

This document describes how to change database log mode from noarchivelog to archivelog.

Step 1: Check the database log mode.

We can check database log mode in below two ways.

SQL> select name,open_mode,log_mode from v$database;

NAME OPEN_MODE LOG_MODE
--------- -------------------- ------------
PRIMARY READ WRITE NOARCHIVELOG

SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 8
Current log sequence 10

Step 2: Change log mode from Noarchivelog to Archivelog mode.

Shutdown the database.

SQL> shut immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

Start the database in mount stage

SQL> startup mount

ORACLE instance started.

Total System Global Area 1560281088 bytes

Fixed Size 2924784 bytes

Variable Size 1006636816 bytes

Database Buffers 536870912 bytes

Redo Buffers 13848576 bytes

Database mounted.

Change database to archivelog mode.

SQL> alter database archivelog;

Database altered.

SQL> alter database open;

Database altered.

Check the log mode.

SQL> select name,open_mode,log_mode from v$database;

NAME OPEN_MODE LOG_MODE

--------- -------------------- ------------

PRIMARY READ WRITE ARCHIVELOG

SQL> archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination USE_DB_RECOVERY_FILE_DEST

Oldest online log sequence 8

Next log sequence to archive 10

Current log sequence 10

How to start/stop and check the status of listener.

This doc describes us how to start/stop and check the status of listener.

How to start listener:

Step 1: Find the listener name from listener configuration file. I.e., listener.ora which is under $ORACLE_HOME/network/admin

[oracle@silver ~]$ cd $ORACLE_HOME/network/admin
[oracle@silver admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

OBIEE =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = silver.apps.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

Step 2: Start listener

Syntax: [oracle@silver admin]$ lsnrctl start <Listener Name>

Below is the example.

[oracle@silver admin]$ lsnrctl start OBIEE
