Oracle Goldengate Extract and Replicat within same DB from one schema to another plus some issues and fixes

-

This is a quick guide for GoldenGate replication within the same database from one schema to another.


Dblogin and add checkpoint table
GGSCI > dblogin userid ggs_owner, password ggs_owner
GGSCI > add checkpointtable ggg.chk

extract parameter file: es1.prm
GGSCI > edit param es1

vi mode
EXTRACT es1
SETENV (ORACLE_SID=orcl)
SETENV (ORACLE_HOME="/a01/app/oracle/product/11.2.0/dbhome_1")
userid ggg, password ggg
EXTTRAIL /gg_01/app/goldengate/product/12.1.0/dirdat/ea
WILDCARDRESOLVE DYNAMIC
EOFDELAY 5
TABLE S1.T1;
TABLE S2.T2;



replicat parameter file: rs1.prm
GGSCI > edit param rs1

vi mode
REPLICAT rs1
ASSUMETARGETDEFS
SETENV (ORACLE_SID=orcl)
SETENV (ORACLE_HOME="/a01/app/oracle/product/11.2.0/dbhome_1")
REPERROR (-1, IGNORE)
REPERROR (1403, IGNORE)
userid ggg, password ggg
dboptions nosuppresstriggers
HANDLECOLLISIONS
MAP S1.T1, TARGET S2.T1; 
MAP S1.T2, TARGET S2.T2;


Configure extract process:
GGSCI > ADD EXTRACT ES1, TRANLOG, BEGIN NOW
GGSCI > ADD EXTTRAIL /gg_01/app/goldengate/product/12.1.0/dirdat/ea, extract eS1
GGSCI > START ES1

Configure replicate process:
GGSCI > ADD REPLICAT RS1, EXTTRAIL /gg_01/app/goldengate/product/12.1.0/dirdat/ea, CHECKPOINTTABLE ggg.chk
GGSCI > START REPLICAT

Done! (ok this is how it supposed to be done and when everything works with no issue.)


There was an issue which caused my replicat process to fail, it took me a little while as I didn't expect this to happen.

In the midst of configuring the Golden Gate replication process, one of our developers changed the definition of the source table, the initial error indicated some sort of bad record, so I alter the replicat process to skip bad records, which continued to fail. 

I finally tried using log dump to find more information, until I see an error with column mapping, which finally ran a bell for me to check for the source and target table definitions. Once I dropped and recreated the target table, everything was good from there.

MongoDB Tips: Kill long running processes

-
This is just a quick and simple script to find all active opid that has been running over 10 seconds and they are running against the databases and collections you can specify in the "ns" filter. It's best to first run db.currentOp(    {      "active" : true,      "secs_running" : { "$gt" : 10 },      "ns" : {$in:["equipment.detachment","personnel.detail","personnel.unavailability","personnel.detachment"]}    } ).inprog.forEach(function (doc) { print(doc.opid); }) and verify your output before you execute the kill command in my experience to make sure you are killing the processes that are meant to be killed. Once verifed, simply run: db.currentOp(    {      "active" : true,      "secs_running" : { "$gt" : 10 },      "ns" : {$in:["<db1>.<col1>","<db2>.<col2>","<dbn>.<coln>...

Oracle Goldengate Extract, Pump, and Replicat

This is just a quick demonstration of setting up extract, pump, and replicate. I prefer to edit the prm files at OS level, but we can also do GGSCI> edit param esource to enter the vi mode to create the prm file. Here are the sample prm files used in the demonstration: prm files: -------------------------------- Source: (2 processes) ~~~~~~~~~~~~~~~~ esource.prm ~~~~~~~~~ EXTRACT ESOURCE SETENV (ORACLE_SID=source) SETENV (ORACLE_HOME="/source/app/oracle/product/11.2.0.3") userid ggg, password ggg EXTTRAIL /ggSource/app/goldengate/product/12.1.0/dirdat/es --Resolves the TABLES to be replicated when they first encounter a dml operation WILDCARDRESOLVE DYNAMIC --Reduce the system I/O overhead of redolog reads EOFDELAY 5 TABLE mine.table; psource.prm ~~~~~~~~~ EXTRACT PDWDSPRD SETENV (ORACLE_SID=source) SETENV (ORACLE_HOME="/source/app/oracle/product/11.2.0.3") userid ggg, password ggg RMTHOST targetServer.example.net, MGRPO...

This post is just a quick guide of MongoDB Ops Manager basic installation and configuration. The bare minimum of getting an instance of MongoDB Ops Manager up and running. We will be working with the latest version of the OpsManager, release version 3.4.7. Prerequisite: To start fresh, we remove any mongodb related RPM. I had Mongod installed as well, therefore, I have extras to be removed. [root@msdlva-dsnops01 ~]# yum autoremove $(rpm -qva | grep mongo) Loaded plugins: langpacks, product-id, rhnplugin, search-disabled-repos, subscription-manager This system is receiving updates from RHN Classic or Red Hat Satellite.
