What is the best Upgrade procedure for AE under Linux

[Achim Maurer]

Hi all,

in the Past used Solaris and did all my updates from AE 9 until 12.1.5  with stopping the App Server (WP/JWP/CP Processees),
then changed utility/automationengine/db Directories to the new Version and started the update wirh ucybdbld utility.

After that restarted the App Server(AE Processes) im Cold Start mode. That worked without problems any time.

Now using Linux and installed it with one installer, so AE Servicemanager and Postgresql Database resides on same System.

How is now the best way to update Servicemanager and DB from for example 12.3.1  to 12.3.3?
May I use the same procedure like described above for Solaris?

Thanks for any hints,
Achim

Hi Achim,

What you describe is pretty much the classical, non-ZDU upgrade path we follow on Linux as well. The gist is:

• install new utilities and engine into new directories
• merge settings from INI files (important! if you just copy your old ini files, you may miss vital new things)
• stop all services
• update the db with the utility from the new tree
• (do anything else the update manual for that particular version may call for)
• (edit, I actually missed the step in the first post): obviously, you need to point it to the new engine directory now, we use a symlink for that. Unless you have overwritten the old engine with the new, which I do not recommend. A symlink allows you to roll back easily and to compare old and new after the update, which is a good thing to have)
• start up again

This works for us. I do believe it should work equally when you used the ONE Installer, because as far as I know it merely does a "partly automated convinience install", but the end result should be pretty much the same.

But since I never used the ONE Installer, I'd possibly wait for at least one more data point from someone who has used it :)

Best regards,
Carsten

Hi Carsten,

Mit freundlichen Grüßen / Kind Regards

Just to let you know. It works like expected to me.

What I did to update the Version after used the OneInstaller  for Installing Automic/Tomcat/DB etc. on Linux:

- /etc/init.d/automicsm stop   (Stopping whole AE incl. DB(PostghreSQL))

- Copied the new Utility/db/AE/awi.war files into the right directories
- Started my AE postgres DB with:
                         bash /data/opt/AE_DEV/Automation.Platform/Analytics/datastore/start.sh /data/opt/AE_DEV/External.Resources/postgresql 5434&
- run  ./ucybdbld -B -X<Path to license file) 
- run  ./ucybdbld -X../db/general/12.3/UC_UPD.TXT
- stopped Database by killing running DB Postgres Process
- run /etc/init.d/automicsm start   (This starts Servicemanager, Webinterface and Postgres DB)
- login over AWI and check if all ok. :-)
- Now we can update the Agents to the newer Version too.

Thanks,
Achim
