we are frequently running the maintenance tasks on production during that
databases are not accessible.
to avoid this we want to switch over to the standby server during maintenace
and after maintenance has been completed
switch back to primary server.During maintenance all data changes need to be
replicated back to production server.
To accomplish this I am planning to setup database replication from
producation database server to Standby server.
Please advise best solutions for this like microsoft trnsaction
replication,Goldengate replication, wansync replication.
I think microsoft trnsaction replication,Goldengate replication doesn't
support complex shema changes to get replicated.
Requirement :
1. 10 databases need to get replicated (with 30GB - 70GB each)
2. these 10 databases will have schema changes monthly.
3. data changes need to moved from standby to production server after
maintenance has been completed.
Please advise
ThanksI don't think that replication in the answer to your challenge.
What you probably want is a hot standby. Replication is not recommended
since you will have frequently schema changes.
I think you should investigate these solutions:
- (Transaction) Log shipping
- Cross linked San solution
- Clustering

First I would want to know why your databases aren't available during the
maintenance periods.
Almost all maintenance steps can be done with the databases on-line.

Are you just blindly rebuilding all indexes, or are you analyzing them
first to determine which ones actually "need" to be rebuilt? Rebuilding
an index that is minimally fragmented gains you nothing. You should be
checking the degree of fragmentation of each index, and rebuilding only
those that need it. Here's a script to get you started:

Use bi-directional transactional replication for this. You will need to stop
the distribution agents while running your optimizations.

I think bi-directional transactional replication is ideal for this. Point
the feed to the standby when you want to do maintenance on the primary. Then
stop the distribution agents, do your work, and restart the agents, and then
repoint to the primary.
When you do your schema changes you will have to tear down replication on
both sides and recreate it after you have done the schema changes.

First I would want to know why your databases aren't available during the
maintenance periods.
Almost all maintenance steps can be done with the databases on-line.

We have very huge tables , reindex will take hours.

Hmm, have you tried using DBCC INDEXDEFRAG. I find for most cases this is
more than suffecient and it's an online operation which means you can avoid
the whole switchover, etc.|||DKRReddy wrote:

Are you just blindly rebuilding all indexes, or are you analyzing them
first to determine which ones actually "need" to be rebuilt? Rebuilding
an index that is minimally fragmented gains you nothing. You should be
checking the degree of fragmentation of each index, and rebuilding only
those that need it. Here's a script to get you started:

databases are not accessible.
to avoid this we want to switch over to the standby server during maintenace
and after maintenance has been completed
switch back to primary server.During maintenance all data changes need to be
replicated back to production server.
To accomplish this I am planning to setup database replication from
producation database server to Standby server.
Please advise best solutions for this like microsoft trnsaction
replication,Goldengate replication, wansync replication.
I think microsoft trnsaction replication,Goldengate replication doesn't
support complex shema changes to get replicated.
Requirement :
1. 10 databases need to get replicated (with 30GB - 70GB each)
2. these 10 databases will have schema changes monthly.
3. data changes need to moved from standby to production server after
maintenance has been completed.
Please advise
ThanksI don't think that replication in the answer to your challenge.
What you probably want is a hot standby. Replication is not recommended
since you will have frequently schema changes.
I think you should investigate these solutions:
- (Transaction) Log shipping
- Cross linked San solution
- Clustering

Best practice for maintenance plans
Hi,
with SQL 2k the maintenance plan wizard proposed defaults for all
maintenance tasks. With SQL 2005 this is gone.
What are the best practices to setup a "normal" SQL 2005 maintenance?
Thanks for any advice
Greg

Greg JimsonHi Greg,
You should be installed SSIS (Integration Service) to be able to use it, or
just to install Service Packets would be enough as well.
Maintenance still stands in the Management node in SQL Server 2005. Go to
Maintenance Plans and right click on it.
Click Maintenance Plan Wizard.

In the "Select Maintenance Tasks" window at the bottom side you will see the
description box which describes each option when you click on them.
For instance, you schedule "Maintenance Cleanup Task" to remove files left
over from executing a maintenance plan.
