Operating Systems AIX migrating solaris DB servers to AIX - resources ? Post 302367556 by zxmaus on Tuesday 3rd of November 2009 03:10:57 AM

migrating solaris DB servers to AIX - resources ?

Hi Guys,

I have a new project where I have to migrate about 150+ database environments from various solaris systems running Solaris 8 / 10 and residing on very different sun boxes (from 25k down to ancient/unsupported hardware) to AIX (power6).

As special bonus for me, about half of these DBs are supposed to become migrated to Oracle once stable as Sybase DBs on AIX.

I know that I can use the RPE2 values to estimate the cpu requirements - but since the memory needs on Solaris seem pretty different from AIX, is there any safe way to estimate at least roughly the memory needs on AIX? For Sybase I can probably choose the value that's assigned to ASE and add 2-4 GB memory for the system and should be safe - but what do I do with oracle since here the memory usage seems to be highly depending on the DB connections and what they're doing?

Has anybody done similar tasks in the past and would be happy to share experiences.

Thank you and regards
zxmaus

Upgrading to AIX 7 vs migrating

NAME
Apache::Session::Serialize::Sybase - Use Storable to zip up persistent data and unpack/pack to put into Sybase-compatible image field SYNOPSIS
use Apache::Session::Serialize::Sybase; $zipped = Apache::Session::Serialize::Sybase::serialize($ref); $ref = Apache::Session::Serialize::Sybase::unserialize($zipped); DESCRIPTION
This module fulfills the serialization interface of Apache::Session by taking the data from Apache::Session::Serialize::Storable and modifying it to work with Sybase IMAGE fields. Note that you do not need to quote these values before inserting into the database, and that if you are using DBI::Sybase, you cannot use the data in a placeholder. If you use Apache::Session::Sybase as your session class, this will all get taken care of. AUTHOR
Apache::Session::Serialize::Storable was written by Jeffrey William Baker <jwbaker@acm.org>; the Sybase-specific data manipulation was written by Mark Landry <mdlandry@lincoln.midcoast.com> for use in an earlier version of Apache::Session::DBI::Sybase and placed here by Chris Winters <chris@cwinters.com>.
