GoldenGate 12.1.2 not firing insert trigger

Getting report of goldengate Replicate process which is shows after upgrade from 11g to 12c.

Even though checkpoint table also upgraded. But Replicate process unable to start.

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

 Solution:

I had to troubleshoot a situation, after GoldenGate capture some DML and replicate that, Oracle database needs to run insert trigger making some business integration.

After to upgrade this enviroment from GG 11.1.1.1 to 12.1.2 and DB 11.2.0.3 to 12.1.0.2, was identified that GoldenGate wasn’t running this triggers


So, found interesting resolution on Oracle Docs:

SUPPRESSTRIGGERS | NOSUPPRESSTRIGGERS


Valid for nonintegrated Replicat for Oracle. Controls whether or not triggers are fired during the Replicat session. Provides an alternative to manually disabling triggers. (Integrated Replicat does not require disabling of triggers on the target system.)

SUPPRESSTRIGGERS is the default and prevents triggers from firing on target objects that are configured for replication with Oracle GoldenGate. SUPPRESSTRIGGERS is valid for Oracle 11.2.0.2 and later 11gR2 versions. SUPPRESSTRIGGERS is not valid for 11gR1.


So, added 'DBOPTIONS NOSUPPRESSTRIGGERS' in the replicat parameter file.



OR


However, altough you probably want most of the triggers not to be executed on the target, it can be possible to override this setting, for example when you implement a heartbeat table.

The way to exclude the trigger from the SUPRRESSTRIGGERS setting is to grant the trigger an exception. This can be done as follows on the target:


SQL> EXEC dbms_ddl.set_trigger_firing_property('HR','trg_tbl_heartbeat', FALSE);'

The result of the statement above is that trigger hr.trg_tbl_heartbeat will go off in the target database.


=================================================================================

2nd.

If above steps are not working and still Replicate process Abended then go for below the steps.

 upgrade Goldengate from 11g to 12c ?

If yes, you have two options :

1) Change the double quotes to single quotes

2) Add NOUSEANSISQLQUOTES into your GLOBALS file and restart the processes
/
NOUSEANSISQLQUOTES is intended for backward compatibility with the parameter files of Oracle GoldenGate versions that predate version 12c, where strings in double quotes are intended to be literals and case-sensitive column names are not supported (whether or not they are within quotes).
