Immediate subscriber updating

While GUIDs, also know as unique identifiers, can also be used to ensure uniqueness, they have their own set of problems.

(For more information on using GUIDs as PKs, please refer to

This article discusses three common problems DBAs are likely to encounter when columns have an identity property that will auto-increment its value when data is inserted.

It failed, giving me the following message: "1753 (There are no more endpoints available from the endpoint mapper)" I determined the port that DTCPing was utilizing and used 'portqry' to retrieve its status; which incidentally was "NOT_LISTENING." Almost all of the forum posts pointed towards a firewall blocking the necessary ports but that simply isn't the case here as the two machines are test boxes and there are no software (Windows firewall, third party, etc) or hardware firewalls between the two.

id=2504.) When you create an identity column, you can specify a start value called a seed and an increment value called an increment. There are three caveats associated with identity columns: You can use any real number as a seed or increment; positive and negative numbers are valid, but fractional, decimal or imaginary numbers are not.

DBAs face several problems when replicating columns that contain the identity property.

Everything works fine except for when i attempt to write to the subscriber database using immediate updating.

That is, the update fails because it is unable to complete the update on the publisher database, giving the following error message: "The RPC security information for the Publisher is missing or invalid.In addition, ASM offers the Cite Track research service, which allows users to define criteria for research alerts.ASM member authors enjoy discounts on page charges, article processing charges (APCs), supplemental material fees, and reprint fees.This article discusses three common problems DBAs are likely to encounter when columns have the identity property, which is defined as an attribute of int, smallint, bigint, decimal, numeric or tinyint columns that will auto-increment their value when data is inserted.Consider a table that looks like this: Columns with the identity property-or, as they are more familiarly known, identity columns-are most frequently used to ensure uniqueness, generally as a primary key.Immediate updating subscribers do not have these replication difficulties as we will see shortly, but first let’s look at some common problems.
