Hi,

Yes, you can install Exadata BPs on non-Exadata. Another case would be if
you run your database on Linux and plan to switchover to Exadata.

According to *12.1.0.2 Bundle Patches for Engineered Systems and DB
In-Memory - List of Fixes in each Bundle (Doc ID 1937782.1)*:

*These patches include fixes for both Engineered Systems and for DB
In-Memory. They can be used on both Exadata and non-Exadata systems, and
can be used for both RAC and non-RAC configurations. *

Regards,
Sve

Thank you. That's a good one:

I do know of one company where installing exadata-specific BP's is a
standard practice for all non-exadata systems, in addition to the exadata
ones. Even shops that don't have any exadata at all might consider
switching from the PSU track to the exa-BP track if they want more
aggressive patching of known issues (with both the associated risks and
benefits of this). Personally I never started installing the exadata BP's
until I started actually administering exadata racks - but now that I have
learned about the exa-BP's, I'd give some consideration to the idea of
switching from PSUs to the exa-BP's across the board anywhere - even if the
shop didn't have any exadata systems at all."

In fact, at the end we were advised to install BP onto non-Exadata. There
was a minor problem with ASM version (aka grid infrastructure) but
switching to manual setup mode has solved it.

Hi Laimsi,

My understanding is that the exadata "bundle patches" can actually be
installed on any system. I think it's just another notch up from PSU's as
far as including a few more known issues - inclusive of some
exadata-specific stuff and some generic stuff. Actually, I bet that if we
read through the list of bugs that are included in the latest exa-BP, we'll
find that lots that aren't exadata-specific. I don't have a good
documentation link or MOS link for this, but my understanding is that the
exadata bundle patch doesn't trigger any special relinks or object
replacements that would break any database running on a normal
(non-engineered-system) server. And just like normal, code paths which are
specific for exadata are simply ignored on non-exadata databases but
nothing breaks.

Maybe someone else here knows of a MOS note where this documented. Or for
a little extra assurance, you could always open an SR and just ask "is it
safe to install exadata bundle patches on any non-exadata system."

Hi



What is the practice of patch levels for Exadata primary and
non-Exadata physical standby databases?



Metalink‘s 1265700.1 states that: “The net effect of this
requirement is that non-Exadata systems must ultimately run Database
Patch for Exadata, which is supported when the non-Exadata system is
being used in a Data Guard environment with an Exadata system.”



I personally read it: install Exadata patch onto a non-Exadata system.

Is this so ?







Thank you in advance,

Laimsi N
