Recover One Table from RMAN Backup on Oracle Multitenant

June 24, 2020 15-minute read

Oracle • RMAN • Backup • Recover

Introduction

As DBA you may be asked to recover just one table or a set of tables to a previous date avoiding to touch any other object in our database.
Fortunately in the last Oracle versions we can use RMAN to directly recover a single table automating what we previously did manually, that is recover the tablespace containing our table along with the system tablespaces in a different instance and then export/import with datapump.
Let’s test this functionality and review the steps it performs.

Prerequisites

We have an Oracle 19c multitenant instance patodb with one pluggable database taller running in a Virtual Machine Instance on Google Cloud Platform that have been backed up using Incremental backups.

For more information on Incremental backups please check RMAN Incremental Backup Strategy for Oracle Database.

RMAN Recover Table

In this example we are requested to recover the table pato.T3 replacing the current one and a copy of the table pato.T5 preserving the latest on the pluggable database taller to one day before at 9:00 a.m.

To recover the requested tables to the desired point in time and renaming one table we need to use these options:

recover table with the list of tables
of pluggable database specifying the PDB which the tables belong to
remap table for renaming the table in the same schema
auxiliary destination for the working directory of this command

  recover table pato.t3, pato.t5 of pluggable database taller
  until time "to_date('2020-06-23:09:00:00', 'yyyy-mm-dd:hh24:mi:ss')"
  remap table pato.t5:t5_old
  auxiliary destination '/tmp/oracle/recover'
  ;

Backup Information

Before starting we need to validate there are full and incremental backups available for our tablespace datos from the pluggable database taller in the previous days:

[oracle@patoracle ~]$ rman target /

RMAN> list backup of tablespace taller:datos ;

RMAN>

In the output we found a weekend full incremental level 0 and two daily incremental level 1 backups previous to our point of recovery, so we can proceed.

Prepare Environment

As the table T3 will be replaced we need to drop it before recovering. We do nothing with the table T5 as we are going to preserve it.
Connect to the pluggable database taller with the schema owner pato to drop the table:

[oracle@patoracle ~]$ sqlplus /nolog

SQL*Plus: Release 19.0.0.0.0 - Production on Wed Jun 24 12:13:40 2020
Version 19.3.0.0.0

Copyright (c) 1982, 2019, Oracle.  All rights reserved.

SQL> conn pato@taller
Enter password:
Connected.
SQL> drop table t3;

Table dropped.

And create the auxiliary directory needed to process this activity:

[oracle@patoracle ~]$ mkdir -p /tmp/oracle/recover
[oracle@patoracle ~]$

Recover Tables Replacing and Renaming

Connect to RMAN and issue the command:

And that’s it, we have our tables recovered.

Validate Recovered Tables

Now we can access our pluggable database taller to check the tables were recovered:

SQL> alter session set container = taller;

Session altered.

SQL> select max(d3) from pato.t3;

MAX(D3)
---------------------------------------------------------------------------
23-JUN-20 08.53.31.623657 AM

SQL> select max(d5) from pato.t5;

MAX(D5)
---------------------------------------------------------------------------
24-JUN-20 12.12.13.042780 PM

SQL> select max(d5) from pato.t5_old;

MAX(D5)
---------------------------------------------------------------------------
23-JUN-20 08.53.31.623694 AM

SQL>

Those single tables were recovered to the point in time requested and no other object were touched!

Conclusion

We were able to recover a single table in our Oracle multitenant database with replacing and renaming options using RMAN recover table functionality.
Also we validated the process is restoring and recovering the minimum system tablespaces along the one containing the recovered tables, and using datapump to export the requested data/metadata and import it into the original database.
