I've recently taken over management responsibility for an application that uses Microsoft SQL Server 2000.
My experience is primarily in Oracle and I've already self educated myself about some of the differences (such as needing to initiate a BEGIN TRAN if I want a rollback segment.)
I couldn't readily find any resources that would coach me in the core differences between Oracle and SQL Server and I wondered if someone could point me in the right direction.
Thanks for your help.Basic Oracle to SQL dictionary
Tablespace = Filegroup
Archivelog = Full Recovery Mode
NoArchivelog = Simple recovery Mode
AutoArchive = well, there ain't no Santa Clause either...
Redo Log = Transaction log
Rollback Area = Transaction log
Block = Page
Extent = Extent (except you have no control on the size)
Sequence = Hmm. About the Easter Bunny...
sys = sa
system = sa
Control File = Remember when you put a tooth under your pillow, and got a quarter...?
System Catalog = Two dozen tables whose names all start with "sys"
SQLPlus = Query Analyzer
Enterprise Manager = Enterprise Manager...sorta
This enough to get you started, or was there a particular area you needed?|||Perhaps this guys book would be useful to you.

Hans.|||I'm fairly comfortable with the tools and the layouts. So most of what you posted is already absorbed.
Let me give you an example:
Myself and my co-worker are both on this project straight from an Oracle shop. We've had no formal training as MS SQL DBA or programmers.
I knew about BEGIN TRAN just from experience. When I told her about it she was slightly shocked/surprised.
I'm looking for other pitfalls/suprises/traps that I might encounter as an Oracle-Centric.
Or do you think I should just bite the bullet and take some classes?|||Hopefully you know that readers block writers in SQL Server, whereas Readers are never blocked in Oracle?|||There's a bunch of stuff here...
obviously it's slanted toward M$
If you know Oracle, SQL Server will be a breeze....
Do you know if the system is using replication or clustering?
If not...It'll be a walk in the park....
And get some good books

Oh, and the forums ain't to shabby either...|||Originally posted by nugenth

Well...You're gonna need to drop the cursor conciousnous...You know how Oracle uses Cursor pointers a lot?
Doesn't work that way here. You need to avoid cursors like the plague
Or do you think I should just bite the bullet and take some classes?
They gonna pay for it? Why not...Maybe South Beach...|||And there's tons of stuff to google..

And the search feature of the forums are useful

That is incorrect.
This is the default settings for transactions in SQL Server (Auto Commit).
Look up SET IMPLICIT_TRANSACTIONS { ON | OFF } in BOL...
System Catalog = Two dozen tables whose names all start with "sys"
This is partical correct, but not advised.. Use the INFORMATION_SCHEMA Views that are used in DB2 and SQL Server but Oracle...|||Originally posted by MCrowley

sequence - identity (thought it was just a different lingo...
control file - sp_configure + sp_dboption, at least
system catalog - contents of master and msdb + system objects in every user database|||oye...it's nor Cursor pointers...
it's reference cursors...
Oracle doesn't move data around like sql server
It's all logical...
Damn, I need another Oracle project...it's been awhile....|||Are DB2 and SQL server not enough ...|||No!
You have to learn how to wash windows as well!
AND know how to make a MEAN margaritta!|||where Rownum() < 100 = select top 100
