Re: Migrating Sybase ASE to SQL
Good luck. Most of the database vendors -- SAP/Sybase included -- give you tools to migrate from "other" competing database vendors. Similarly MS also provides you some migration tool. The data...

Thanks Rob. I don't frequent the Sybase side of things terribly often, so I suppose I was a little out of my element

Thank you Avinash. I do not deal with Sybase products terribly often, so I appreciate your insight very much.

I've done a ASE -> MS-SQL migration - in my experience 90% of the task is easy - but depends what code has been written. If you have a large amount of data I'd recommend splitting the data migration...

Creating a named cache will not help this - this is spinning on the spinlock for the object DES structure - which has pointers to indexes in memory, etc - but it does NOT contain catalog information....

Thanks for the information. I should be able to identify heavily used procedures - will see how much that improves things.Can I drop the proc if its bound ? How would you bind temporary tables ?

Mike, FWIW, I did some testing on one of our apps some years ago to try to reduce desmgr spinning. This application uses temp tables exceptionally heavily with the driving tables created outside the...

Thanks for this. Very useful A little confused with the results....Binding top 16 tables, reduces CPU by 9% but binding all tables reduces CPU by 5% Binding tables and procs uses more CPU than binding...
