Oracle Data guard

[Francesco_13]

Hi,

i want to install oracle data guard for my rac cluster oracle two-node (hp-UX 11.23)

in other server.

Rac it's Itanium based, Dataguard is't PA-Risc based.

It's possible with this different architecture?

Oracle dataguard concept at pag.2-6 tell that it's not possible. But yo know if have any workaround?

Thanks.
Best regards.

Hi,

This is not possible to install RISC based apllication/componenet on Itanium based servers.

Oracle has releases that are architechure specific. Even the OS is a little different on the two platforms.

When the OS is truly unified on HP-UX 11i v3 Oracle will need some time to catch up.

Oracle compiles and links itself on install, and the code and processes are different on the two processor architectures.

I do not believe this(your proposed) setup will work. Surely you need to check with oracle if its supported or not.

Hi,
i'm sorry but i have wrong explained my question.

Data guard configuration it's with two Oracle database (primary and stand-by in same or different node ) .
My question it's if it's possible that the two database in different nodes, can be in different OS architecture(64 and 32 bit)

Thanks.
Best regards.

Hi Francesco,

It seems that's possible depending on your Oracle version (9iR2 and above).
This is called Logical standby.

cf. Metalink doc id 234508.1 "Certification and Prerequisites for Oracle DataGuard"
and
http://asktom.oracle.com/pls/ask/f?p=4950:8:12217528100432569435::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:4499986040885

this will explain it to you.
This includes links to the relevant documentation.
