Using DBMS_STREAMS_ADM To Cleanup GoldenGate

Filed under: 12c,GoldenGate — mdinh @ 5:33 am

This is really messed up. I chose GoldenGate because I did not want to mess around with streams.

When using Integrated Capture or Delivery, then knowing streams is a prerequisites.

Apologies as the format is not pretty.

The QUEUE table was indeed missing and this is what I get for monkeying around.

To resolve the issue –  exec DBMS_STREAMS_ADM.REMOVE_STREAMS_CONFIGURATION();

Alternate script prvtlmpg.plb (included in the Oracle GoldenGate installation directory) to the mining database to work around this limitation.

Oracle GoldenGate Workaround prvtlmpg

This script provides a temporary workaround for bug 17030189.
It is strongly recommended that you apply the official Oracle
Patch for bug 17030189 from My Oracle Support instead of using
this workaround.

This script must be executed in the mining database of Integrated
Capture. You will be prompted for the username of the mining user.
Use a double quoted identifier if the username is case sensitive
or contains special characters. In a CDB environment, this script
must be executed from the CDB$ROOT container and the mining user
must be a common user.

===========================  WARNING  ==========================
You MUST stop all Integrated Captures that belong to this mining
user before proceeding!

Goldengate 12c has some security features to allow/prevent unauthorized access.

Be careful. Incorrect IPADDR or PROG is used will prevent Pump Extract delivery to target server.

So what’s different from this post versus other posts? I share my mistakes with you.

Did you know there was a DEFAULT domain? If you didn’t, neither did I and only found out by using

info credentialstore

alter credentialstore add user ggs_admin alias ggs_admin domain admin

Automating DG Broker

Filed under: 11g,awk_sed_grep,Dataguard,oracle,shell scripting — mdinh @ 2:11 am

I have been applying PSU lately and what’s so hard out it?

Four+ databases running on Primary with DG Broker for standby.

There are no conventions, as some standby databases have dr appended to primary name while others have 2 appended to primary name.

I wanted to view the DG configuration for currently active instances and show_dg_config.sh will show me this.

Next, I want a faster way to shutdown DG by having syntax generated and  gen_dg_cmd.sh does this.

Guess I could have taken it further by creating a shell script to create shell scripts to shutdown DG.

One day when I am really bore, I might OR may be you are so nice to complete my mission.

Tested on AIX 7.1

Note: the ps -ef syntax is for AIX and will not work with Linux.

See below for the Linux alternative.

$ ps -ef -o args|grep ora_smon|grep -v grep|awk -F"_smon_" '{print $2}'
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
