I am currently running: "Adaptive Server Enterprise/15.5/EBF 18657 SMP ESD#4/P/Sun_svr4/OS 5.8/asear155/2545/64-bit/FBO/Thu Jun 16 10:29:40 2011" with following databases sizes:
267,000.0 MB
122,000.0 MB
78,500.0 MB
and, of course, many more much smaller in size. I am looking for the best practices, detail steps (and gotchas) of moving these databases from Sybase ASE 15.5 on SUN Solaris to ASE 15.7 on Linux (RH6 64-bit). I used the cross-platform dump-n-load many years ago to migrate from the same databases from Windows to SUN, and now need to move to company's enterprise platform. I will be working on testing the process and procedures in test environment starting next week.
By-the-way, what EBF/ESD/SP level should I install?
Thanks for insight and direction.
Joe,
Read about:
sp_dumpoptimize "archive_space = maximum"
and
http://scn.sap.com/thread/3400442...
I started to use the dumpoptimize option so that all of the pages would exist in the dump image.

Hi Joe,
you can also use the R3load option if it is a SAP system which you are running, but I think it is not in cause of the version.
On RHEL6 you can also use hugepages.
Have a look at this blog for migration and this one for hugepages.
Is it a OLTP or OLAP DB which you want to migrate?
Regards,
Jens
Jen: thanks so much for the heads up on the hugepages -- i use them on our Oracle installs, but had not considered the use of them on this migration -- so, will enable their usage based upon the blog you provided. I had already perused the other blog regarding the migration.
this migration for OLTP databases.
thanks again,
joe
