IXC452I
THE NON-XCF CONNECTOR NAMED conname RESIDING ON SYSTEM sysname MAY INTERFERE WITH XCF'S USE OF STRUCTURE strname

Explanation

A non-XCF connector is connected to a XES list structure that is defined to XCF for signalling. The name of the connector and the system from which it did the connect is identified. A structure used by XCF for signalling should be dedicated exclusively to XCF in order to ensure correct operation of the signalling service.

Some of the consequences if the non-XCF connector remains connected to a structure used for signalling:
  • Signals may be lost.
  • XCF may not be able to connect to the structure.
  • Rebuild processing may never complete.
In the message text:
conname
The connection name by which the connector is known. This name was specified via the CONNAME parameter on the IXLCONN macro invocation.
sysname
The name of the system on which the connector resides.
strname
The name of the XES list structure defined to XCF as a signalling path.

System action

If the structure appears to be in use for signalling already, processing continues. If the structure does not appear to be in use for signalling, XCF disconnects from the structure.

Operator response

If XCF is not supposed to use the structure for signalling, enter a SETXCF STOP path command (for each direction that applies) to prevent XCF from attempting to use the structure and thereby interfere with the use of the structure by the other connector(s).

If XCF is supposed to use the structure for signalling, consult the system programmer to determine whether this connector is a legitimate user of the structure. Usually steps should be taken immediately to force the indicated connector(s) to disconnect from the structure. If not, the XCF signalling service may fail in a variety of ways due to interference from the non-XCF connector.

System programmer response

Do not allow non-XCF connectors to connect to a structure that is to be used for signalling. Simply being connected to the structure can prevent the XCF signalling service from operating as intended.
