26ai- Using Tags in Oracle Data Guard Broker

By -

 Oracle AI Database 26ai adds tagging support to Oracle Data Guard Broker, allowing administrators to attach custom metadata to configuration members.

With tags, you can attach your own information to Data Guard members. Think of it as adding labels to databases so they become easier to identify later.

For example, you may want to store:

* Deployment location
* Environment type
* Build date
* Owner team
* Compliance information

Before using tags, the feature must be enabled.

DGMGRL> EDIT CONFIGURATION SET PROPERTY TagMode=1;
Property "tagmode" updated

In this demo, I added two tags to the member dg1.


The first tag stores the location of the database:

DGMGRL>  EDIT MEMBER dg1 SET TAG location='BABOL';
Tag "location" updated in "dg1".

The second tag stores a configuration date:

DGMGRL>  EDIT MEMBER dg1 SET TAG configuation_date='2026-02-25';
Tag "configuation_date" updated in "dg1".

Now we can query V$DG_BROKER_TAG and verify the tags:

SQL> select member,name,value from V$DG_BROKER_TAG;

MEMBER  NAME                VALUE
------- ------------------- --------------------
dg1     location            BABOL
dg1     configuation_date   2026-02-25

Oracle 21c Enhancements for TTS Export/Import

By -
  In Oracle version 21c, new features have been introduced for transportable tablespace (TTS) export/import. This article explores these capabilities in detail. Improvement 1: Parallel Execution of TTS Export/Import In Oracle 19c, TTS export/import operations could not be executed in parallel, as demonstrated by the following: Connected to: Oracle Database 19c Enterprise Edition Release 19.0 .0 .0 .0 – Production ORA-39002: invalid operation ORA-39047: Jobs of type TRANSPORTABLE cannot use multiple execution streams. Oracle addressed this limitation in version 21c, enabling parallel execution for TTS export/import: [oracle@oLinux7 ~]$ expdp directory=drm dumpfile=TTS_DUMP%U.dmp transport_tablespaces=tbs1,tbs2 transport_full_check= y parallel= 2 Export: Release 21.0 . 0 . 0 . 0 – Production on Tue Oct 12 06 : 48 : 54 2021 Version 21.3 . 0 . 0 . 0 Processing object type TRANSPORTABLE_EXPORT/STATISTICS/TABLE_STATISTICS Processing object type TRANSPORTABLE_EXPOR...

Automatic Service Failback to Preferred Instance in Oracle RAC 19c

By -
  As you know, in a RAC environment when creating a service, you can define   preferred instances   and   available instances . In this case, the service will by default run on the preferred instance. If for any reason the preferred instance fails, or the entire node becomes unavailable, the service will be moved to the available instance. Even after restarting the preferred instance, the service will not automatically fail back; it will continue running on the available instance. To move it back to the preferred instance, you need to manually perform a  relocate  operation. Example: In this example, we create a service named  mysrv  in Oracle 11g: [ grid@node1 ~ ]$ crsctl query crs releaseversion Oracle High Availability Services release version on the local node is [ 11.2 .0 .4 .0 ] [ oracle@node1 ~ ]$ srvctl add service -d mydb -s mysrv -r instance1 -a instance2 After creating the service, start it. You will see that the service is runnin...

Oracle 21c — Setting Compression Attribute for Indexes During Import

By -
  In Oracle 12cR1, a new feature was introduced that allowed us to enable or disable the   compression   property for tables during a dump import. This was done using the   TRANSFORM   parameter in the   impdp   command: SQL * Plus: Release 12.2 .0 .1 .0 Production SQL > select compression from dba_tables where table_name = 'TBL1' ; COMPRESS -------- DISABLED SQL > drop table usef.tbl1; Table dropped. [oracle @oshost ~ ]$ impdp usef / a directory = drm dumpfile = test.dmp tables = usef.tbl1 TRANSFORM = TABLE_COMPRESSION_CLAUSE:\"ROW STORE COMPRESS ADVANCED\" SQL > select compression,COMPRESS_FOR from dba_tables where table_name = 'TBL1' ; COMPRESS COMPRESS_FOR -------- ------------------------------ ENABLED ADVANCED This feature was only available at the  table level , and there was no way to control index compression during import (in Oracle 12c). However, in  Oracle 21c , as a new feature, you can now enable (...
