If you have a Gmail, Yahoo, Hotmail or similar account, then you are already using webmail. RMAN> CATALOG START WITH '/tmp/auxiliary.' Ħ) Recover the destination database with the cataloged incremental backupħ) Repeat Step-3 to 6 to sync the target with source as close as possible.Ĩ) For final cutover repeat Step-3 to 6 while source database is in read only mode (to maintain consistency).Īdditionally refer to Doc ID 1338193.1 for more details.Larger businesses may often condemn webmail, but most of us are already familiar with it. RMAN> BACKUP INCREMENTAL FROM SCN 3162298 DATABASE FORMAT '/tmp/auxiliary_%U' tag 'INCREMENTAL_1' Ĥ) Transfer all backup sets to destination serverĥ) Catalog the backups in destination database controlfile. Therefore, From the above you need to backup from SCN 3162298ģ) on source database - Take incremental backup using SCN
You need to use the 'lowest SCN' from the queries, in this example is SCN: 3162298. Where file# not in (select file# from v$datafile where enabled = 'READ ONLY') SQL> select min(checkpoint_change#) from v$datafile_header You need to use the 'lowest SCN' from the queries below: On the Target database, find the SCN which will be used for the incremental backup at the source database: You can follow the following steps to reduce the downtime during migration:Ģ) On Target database - Restore database from the level 0 backup from step-1ģ) On Target database - Determine the SCN

Oracle Dataguard has licensing requirements, but no additional license might be required in your particular case and for a temporary purpose - but please consult with Oracle support and do not rely on any licensing information you read here. There is documentation and plenty of examples on the web, for example: In such case, you create a physical standby database from active database duplication or use RMAN backups and simply convert the standby database to your primary database at your convenience, which takes only seconds. If you have time to prepare the switch-over to a new server and need to reduce downtime to a minimum, then Oracle Dataguard might be your best option. Depending on size and infrastructure and if downtime is possible, your easiest way might be to simply shutdown the database and copy all the data files to the new server. Nobody can guess your technical infrastructure. There's more information required beside your OS and database release version in order to determine your best option.

On the go live day i can stop the app and take one final level 1 backup and restore.I am only concerned that We have a daily rman at night which deletes archives i am confused that if taking level 0 in the day and full backup which deletes arvhives at night and then again taking level 1 might haveĢ)I can restore the DB today and keep in mount state and go on applying the arvhives for the next 4 days until go live day, but i am worried that on the go live day when i will try to open the database if it will give any errorĬan you all please advice which could be a fastest method
If the Golive is after 5 days i will take Level 0 backup today and for the next 3 days will take level 1 backup and restore on the new server. I have the below two plans and challenges kindly advice if these are ok or we can do some other way. On the go live day i can easlity take an RMAN backup and restore but i am just looking at the fastest way to do this. The OS (Win server 2016) and DB version ( 11.2.0.4)are same, we do not have license for golden gate. Hi all, we have an activity of migrating our production environment to a new server.
