I have my databases running on SQL Server 2005.
I have Transactional replication setup between 2 databases - source being my transaction db and the target being the reporting database.
I am going to add a new article to the existing publication, and my question over here is when I add the the new article do I have to generate a new snapshot and then reintialize the subscription.
And also when I am generating the new snapshot will I be able to access both the source and the target databases.
Thank you all in advance.

When you are generating the snapshot you will be able to access both the publisher and subscriber - from what I remember the snapshot agent takes a schema lock on the tables for which the snapshot is being generated and if the snapshot generation process takes a very long time then you might see blocking issues on the publisher.

Thank you very much.
So, will it generate snapshot only on the new article or all the articles which are getting replicated.
Thank you again for the reply.

The snapshot will be generated for all articles being replicated (i.e. all the existing articles plus any new articles being added to the publication) - however the distribution agent will only create the new article(s) and copy in the data for the new article(s).
If you check on replication monitor - in the Snapshot Agent tab you'll see the snapshot for all articles being generated and if you go to the distribution agent (the "Distributor To Subscriber History" tab) you'll see that only the schema and data for the new articles are applied.

If you add the article using scripts and then generate the snapshot, the snapshot agent should only add the new articles and limit the impact to both the publisher and subscriber to just the new article.

Could you please clarify that?
When I add an article thru the GUI it generates a full snapshot?

There are 2 options that need to be set to false for the publication in order to add an article and only snapshot that article vs the entire publication.
immediate_sync and allow_anonymous

Is it possible to add more than 1 article at a time without having to do a full snapshot?
I did it before and had nixed results.

Either your fingers were misplaced on the keyboard or you're using a far newer version than I've ever seen. 😛

I had to replace my keyboard.
I'm going from SQL Server 20122 Enterprise to SQL Server 2014 Enterprise.
If you add multiple articles do you have to perform a full Snapshot?

OK, Thanks.
I had added multiple articles at a time but I kept getting errors that it could not find various articles that had already been published.
I can't determine why?

Where do you specify that?
I could not find it in the article.
