Restart – SIHA – HAS

Voodoo with init parameters and Oracle Restart

Uwe Kirchhoff, one of the best techies I know in the entire Oracle CSS (formerly ACS) Support, mailed me before the Christmas holidays with a simple question. He discovered that altering init.ora parameters in a session does not necessarily write the parameter down into the spfile. Sounds a bit like Voodoo with init parameters,  and Oracle Restart has a role in this story as well. If you don’t have or do not plan to use Oracle Restart, then this is not interesting for you. But of course, you are free to still read it 🙂

Oracle RESTART: Make sure you’ve patched your Oracle homes

Oracle RESTART: Make sure you've patched your Oracle homesThis blog post title sounds a bit weird, doesn’t it? Oracle RESTART: Make sure you’ve patched your Oracle homes. Why the heck should you patch your database homes upfront?

Oracle RESTART: Make sure you’ve patched your Oracle homes

Well, there’s an interesting issue happening. When you work with Oracle Grid Infrastructure, no matter if you operate a cluster or “just” use Oracle Restart, you’ll have to upgrade GI to Oracle 12.2 first before you can manage 12.2 databases with it. That’s not new. It’s a well understood rule.

Downgrade Oracle Restart 12c – Grid Infrastructure only?

Oracle RestartCan you downgrade your Oracle Restart installation from Oracle 12c back to Oracle 11g?

Actually there’s no real direct downgrade supported for Oracle Restart. But of course there’s a way to do it.

Basically it is:

  • Deconfigure Oracle Restart in 12c
  • Configure Oracle Restart in 11g

But wait a minute. It is very important to know if you have upgraded your database already. If that is the case then first you MUST downgrade your database(s) as you can’t manage a higher version Oracle Database with a lower version Clusterware.

So first of all, please downgrade your Oracle database(s) first:…

Upgrading ORACLE RESTART from 11.2 to 12.1

First of all, Oracle Restart is deprecated in Oracle Database 12c. Deprecation means the product is still supported, you can open SRs, you’ll get bug fixes – but we won’t do further development of the product or feature.

But a customer (Thanks to Jaco de Graaf for bringing this to my attention!) had a question via the blog about the best approach to upgrade his Oracle Restart configuration …
