Install latest version of Oracle Goldengate 12

With Oracle Goldengate 12 there is now a big change on the way to install: there is an installer!

Up to Oracle Goldengate 11 every new patch was a new complete version. With Oracle Goldengate 12 you need to install a base version and then the latest patch.

Here is a quick sum up of the instructions (done on AIX, but is similar on Linux):

  1. From Oracle website download the Goldengate 12.1.2.1.0 for your operating system
  2. From Oracle support note 1645495.1 download the latest patchset for Goldengate. Check the availability for your OS.
  3. Unzip both downloaded files
  4. Call the <download_dir>/ggs_AIX_ppc_shiphome/Disk1/runInstaller
  5. Follow the instructions by choosing the target DB version and install directory (I recommend $ORACLE_BASE/product/gg)

We have now Oracle Goldengate 12.1.2.1.10 installed.

Interesting enough is that Oracle Goldengate 12.1 still uses the OPatch version 11.2.0.1.7, taken probably from Oracle 11.2.0.3, as we can see from the line “OUI version : 11.2.0.3.0”.


Solution for slow login after installing Oracle Linux

After installing Oracle Linux on Virtualbox, I noticed that login in was quite slow. Between the time we enter the login and the moment it asks the password it takes a few seconds.

The solution was to disable the usage of reverse IP resolution on the ssh server.

It can be done by adding/changing the following line on /etc/ssh/sshd_config

UseDNS no

And restart the ssh deamon:

# service sshd restart
Stopping sshd:                                [ OK ]
Starting sshd:                                [ OK ]
