INF: SQL Server RPC Uses Make/Break Connections

 * }

Q138515

-

The information in this article applies to:


 * Microsoft SQL Server version 6.0

-

SUMMARY
Microsoft SQL Server versions 4.21 and 6.0 use make or break connections for executing server-to-server Remote Procedure Calls (RPCs). This means the RPC connection is not maintained after its execution. The SQL Server 4.2 documentation incorrectly indicates that RPC connections may be maintained.

MORE INFORMATION
SQL Server for Windows NT platforms including versions 4.21 and 6.0 implements RPCs through DB-Library connections, which allow server-to-server RPCs using any IPCs supported by SQL Server, not just named pipes, as in the case of OS/2 SQL Server versions. The RPC connections are immediately terminated after their executions, and it is not possible to maintain the connections with the current versions of SQL Server.

In the SQL Server 4.2 "System Administrator's Guide," page 267 and 268, section "Setting the Server Option," it is incorrectly stated that you can configure the SQL Server to either maintain the RPC connection or allow it to timeout. If you try to set this option, SQL Server 4.21 will not give you any error, but the RPC behavior is not affected.
