Data Retrieval is Slow

I have a database with a table that holds 30 million rows. Clients have
access to only those records that concern them. The problem is they want to
have access to all their data at once with the largest resultset
returning1.5 million rows.
Having toyed with the indexes, performance monitors and the like, I still
can't get the data to the client fast enough.
Could you offer any advice on what I should do?
Thanks

LOL. Manage their expectations? ;)
But, realistically, how can anyone do anything practical with 1.5
million rows at once? There must be some better way of presenting the
data without giving it all to them at once (obviously I'm making this
statement with absolutely no knowledge of your situation so I could be
full of it ;) )

Data Migration using Transactional Replication

I need to move my database servers from one location to another. The issue is that I have over 200 databases to move and my clients can't afford a downtime. The collective volume of all the databases is over 2.5 TB and growing.

I am thinking to copy these databases in batches over the WAN to the new location and replicate them using Transactional replication till I have all the databases moved and synchronized.

Will it be wise enough to use replication for synchronizing 200 databases or is there a better approach which I can use to move these databases with minimum downtime and compromise on performance of applications.

Note: Migration is from SQL Server 2000 to SQL Server 2005.

Thanks in advance.

Riteshi do not think replication is going to be easy and effective solution for 200 DB with 2.5 TB. replication has its own set of rules, issues and overheads. better move a few db at a time (backup/restore or detach/attach) and then point the application using those databases to the new db server.

Data Migration Oracle 7.16 to SQL Server 2000

Hi,

I have been asked to look at optimising a Data Migration Strategy for one of our clients. I am quite new to Data Migration (I'm actually a system designer!).

The migration is from a legacy Oracle 7.16 Db to a SQL Server 2000 environment.

The legacy Db has some large tables - 30 Million+ rows

Table/column Mapping is 1:1

At present we are using DTS to import into the SQL environment.

My question is: Is there any way to leverage the Oracle 7.16 export to speed up the migration process?

Any advice would be appreciated.

Many thanks

Mike

this forum is for sql server 2005 integration services...not sql server 2000 data transformation services.

i suggest that you post your question to the microsoft dts newsgroup.
