Estimating needed size when replicating

Hi,
Can somebody tell how to make an estimation of the size needed when creating a 'consult' DB with snapshot replication ?
Thanks !Five liters.

If you can be a bit more specific, I can be a bit more serious ;)

-PatP|||:rolleyes:
sorry, i ment how much extra size is there needed besides the size of the database itself, like for systemtables and that kind of stuff...|||The overhead within the database is trivial. I'd allow a megabyte or two tops.

Now the distribution server (both database and snapshot file space) can be a very different story!

-PatP|||There is no difference in size between the published database and the resulting snapshot on the subscriber. Subscriber's disk subsystem needs to be as fast if not faster than the publisher's. Depending on the origin of invocation (I hate this style of writing myself, so don't laugh) of the distribution agent subscriber's CPU may take quite a bit of a hit. Network, interestingly, is very often the bottleneck. To minimize its affects, use Alternate location with compression (default location does not support compression option).|||There is no difference in size between the published database and the resulting snapshot on the subscriber.

Network, interestingly, is very often the bottleneck. To minimize its affects, use Alternate location with compression (default location does not support compression option).At least on my servers, I get a handful of tables in the publisher that track the replication details (like syspublications, sysarticles, etc). The overhead is trivial, but it is there.

I've never had problems with disk speed... The distributor always takes up the slack for me.

I never use compression with databases. Maybe that's because I got bit so badly years ago, but I've never been able to justify doing it since.

-PatP|||Pat, "years ago" alternate location and compression weren't supported, so I don't know what you're referring to ;)

Estimate Snapshow Duration

Dear all,
I am going to set up a snapshot replicate. it will run nightly. The size of
DB is around 2GB, does anyone know how long will it take to completed the
snapshot replication. Is there any way of estimate the duration? Doesn't have
to be very accurate, a rough figure will do.
Thanks,
Jas
Jas,
this is almost impossible, as your network bandwidth at the time of the
replication and the indexes you have on the tables are just two factors
that'll change the result radically. Perhaps you can 'calibrate' the system
yourself in a rough way by replicating a table of 100MB with representative
indexes to a dummy database and then multiplying the result by 20 - just a
finger inthe air, but will give you some idea.

ErrorCode 1038 during push replication

I’m setting up transactional replication, the snapshot generates fine, but I
get error code 1038 “Cannot use empty object or column names. Use a single
space if necessary.” when the distribution agent does the push replication
and reaches a particular SP.
Something to note is that table names wrapped in brackets (found in SQL
scripts in the snapshot folder) are being converted to quotation, is that
caused by SET QUOTED_IDENTIFIER ON?
so this: FROM [Pub_Articles-Keywords] StaArtK
is converted to: FROM "Pub_Articles-Keywords" StaArtK
The following is the detailed error log. Your help is appreciated.

Hi Moshe,
You would need to replace the "" in the following code fragment with '':
SELECT t.priority, a.ArticleID,
isnull(dbo.SF_PUB_GetAuthorByline(a.articleid),"") toptext,
To make your procedure compliant with quoted_identifier on setting. You can
search this newsgroup for some of the responses I made in the past on how
this came to be. Note that this translation should be done automatically for
you by the SQL2005 snapshot agent.

Error: The process could not bulk copy out of table '[dbo].[syncobj_0x3944323636373031]

SQL Server 2000 error message:

The process could not bulk copy out of table '[dbo].[syncobj_0x3944323636373031]'.

Snapshot replication was running fine up until last week. The e drive on the system failed. The server was rebooted and the drive returned. Since then the replication has failed. (e drive is the location of the database and log files)

The database is approx. 12 gig. I googled the error message an found several references to the drive being full. So I tried to map the replication to a different drive. The replication fails with the same error.

Also tried to drop and recreate the replication process. Still the same error.

Any other ideas?

TIA

Joel

You dont have enough permission to write to the destination database
or
you Sql service account dont have right to access the replication snapshot folder
