I need advice about oracle goldengate 11.1.1 ,
We have 30 oracle 11gr2.0.2 standard edition databases in different sites and it is identical databases so we need implementing GoldenGate to have schema replication
between all databases please advice what is the best design to do that and have compatible with network failure so I have read about multi topology using in goldengate
Bi-directional peer-to-peer distribution and how many goldengate processes I need in every instance .

Hi Ravi,
Do you mean you have triggers on replicated tables which use sequences?
It is hard to advise without knowledge about your architecture and replicat logs.
Try to check firing properties for a trigger maybe it is the problem.

Thanks,

Hello Gleb,

Back to trouble you :(

We have lot of sequences used in our application and hence we have it in our scripts.

I do not see GoldenGate replicating this, any idea on how to get the sequence thing working?

Ravi

Hello Gleb,

Thanks for all the help and this wonderful installation steps. Currently i am able to get Active-Active working with GG. The mistake i did was passing wrong user name. with the correct username with TranLOGOptions, it worked fine.

Still not done, lot of other schemas i would be trying this, so i am sure to trouble you more if i need help :) hope you dont mind.

Regards,
Ravi

Thanks Gleb,

I am trying to get Active-Active situation with our GoldenGate.

Though basic thing works, only with DML operations we are stuck with data looping.

From Oracle Admin Guide for GoldenGate (E17341-01, Page 82) it says to make use of :

Hi Ravi,
You can check supplemental logging for the table in the view dba_log_groups.
The simplest way to enable supplemental logging is to use dbms_capture_adm.prepare_table_instantiation procedure.

I am sorry I am bit lost about the second question.
What do you want to achieve?

Thanks,
Gleb

Hello Gleb,

Yes we have primary keys on replicated tables.

I have not specifically created supplemental logging enabled for tables. could you please guide me how to do that?

Also few suggest to make use of below in the Extract, i tried this but now the replication itself has stopped (as i am not able to give the user name of replicat user here as it is not created here, if i do give user name of replicat user the extract does not start)

Hi Ravi,
Do you have primary keys on the replicated tables?
Do you have supplemental logging (what columns/keys) enabled for the tables?

Thanks,
Gleb
