Error 7211



Message text

Can't open a connection to site '%S_SRVID' because 'set up channel' message was not acknowledged.


This error occurs when Adaptive Server is unable to execute a remote procedure call (RPC) on a remote Adaptive Server, Backup Server, or Open Server application because the remote Server did not acknowledge the connection message sent by the local Server.

One reason for this error is that the physical connection has died before a response was received. The transaction is then aborted.

It may also occur if two access attempts occur within such a short time frame that the first physical connection established has not yet timed out.

NoteIn this write-up, “Server” is used to indicate an Adaptive Server, Backup Server, or Open Server application.


To find out why this error is occurring, perform the following steps:

  1. When automatic timeouts are enabled, a timeout occurs when there is no activity for one minute. If you believe timeouts are occurring, consider disabling automatic timeouts by issuing this command:

    1> sp_serveroption <server_name> "timeouts", false
    2> go

    Where <server_name> is the name of the Adaptive Server for which you are disabling automatic timeouts.

  2. Check the error log for both the sending server and the receiving server. If other errors exist, refer to the write-ups in this manual for information about recovering from them.

  3. If, after resolving any problems found in steps 1 and 2, you still get error 7211, call Sybase Technical Support.

Additional information

For more information about managing remote Adaptive Servers, refer to the chapter “Managing Remote Servers” in the System Administration Guide: Volume 1.
