Rolling Forward a Physical Standby Database Using the RECOVER FROM SERVICE


Hi
Since Oracle 12c we can recover standby only by accessing the standby database/site, no need to copy nor transfer any file
Short and easy - just copy and paste
enjoy :)

Standby Database Name: STBY
Primary Database Name: PRIM

On Standby
sqlplus / as sysdba
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
SHUTDOWN IMMEDIATE;
STARTUP NOMOUNT;
ALTER DATABASE MOUNT STANDBY DATABASE;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

rman target /
RECOVER DATABASE FROM SERVICE PRIM USING COMPRESSED BACKUPSET NOREDO SECTION SIZE 120M;

sqlplus / as sysdba
SHUTDOWN IMMEDIATE;
STARTUP NOMOUNT;

rman target /
RESTORE STANDBY CONTROLFILE FROM SERVICE PRIM;

sqlplus / as sysdba
ALTER DATABASE MOUNT STANDBY DATABASE;

rman target /
CATALOG START WITH '+DATA/STBY/DATAFILE/';
SWITCH DATABASE TO COPY;

sqlplus / as sysdba
set pages 0 verify off feed off term off echo off
spool /tmp/clear.sql
select distinct 'ALTER DATABASE CLEAR LOGFILE GROUP '||GROUP#||';' as cmd from v$logfile;
spool off
@/tmp/clear.sql
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

For Oracle 11g there is a longer version, see Steps to perform for Rolling Forward a Physical Standby Database using RMAN Incremental Backup. (Doc ID 836986.1)

Connect to Oracle Database server through ssh tunnel

Image
Last week I needed to connect a database from remote using VPN. The VPN is connected to a secured network, so I couldn’t connect directly to the database. Since I am using Toad for Oracle which is based on oracle client – I needed a transparent solution for that connection. At the past I wrote a post about Using ssh X11 tunnel through a bastion host to connect to a database server  , at that post I described how to forward SSH and X11. Now I will describe a way to connect to the database using SQL*Net (usually port 1521) on Windows. Download plink from https://www.putty.org , you can download putty package or just standalone plink. Run the following command line: plink -N -L localport:dbserver:dbport getwayuser@getwayserver Do this on both machines (REMOTE PC Windows machine and the server you have access to - Gateway) to chain the SSH tunnels. Example: Gateway server (assuming Linux): ssh -N -L1521:dbserver:1521 dbserveruser@dbserver Your PC: plink -N...

Setting up an Observer

Image
Setting up an Observer Observer is an automatic data guard broker, it can be installed with either the Oracle Client Administrator software or the full Oracle Database software. It is preferable that the observer would run on a different host than the primary and standby databases, using the same network as any end-user client or application. The host should be located In a third, independent location or at least isolated as much as possible from the standby database. Make the observer highly available by configuring auto restart on the same server or on an alternate host. These are the steps for setting up the observer: Enable flashback on Primary & Standby: Primary: sqlplus> alter database flashback on ; Standby: ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL; alter database flashback on ; ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT; Update db_lost_write_protect on Primary & Standby: SQL> alter system set db_lost_write_protect=...

Data Guard - Changing IP Addresses

Image
When changing IP of a host we should update/recheck the following places: /etc/hosts or DNS listener.ora tnsnames.ora Database parameters (local_listener, remote_listener) Data Guard configuration This document is also relevant when changing the IP address of the connection between the hosts, other than the original IP addresses we used during the installation. When installation is done using the hostname and not the IP address, most of the changes are not relevant except for /etc/hosts. In this document, I will describe how to change the Data Guard Broker configuration. Dataguard configuration Show the environment DGMGRL> show configuration Configuration - dr   Protection Mode: MaxAvailability   Members:   pdb7 - Primary database     fdb7 - Far sync instance       sdb7 - Physical standby database Fast-Start Failover: DISABLED Configuration Status: SUCCESS   (status upd...
