SYMPTOMS
Messages on the host may be stuck in the Remote Spooling Communications Subsystem (RSCS) queue even though the Microsoft Exchange OfficeVision/VM (OV/VM) Connector is working properly. Stopping and then restarting the Exchange OV/VM Connector clears the backlog.



CAUSE
The RSCS link definition for the Microsoft Exchange Server VM Node may be incorrectly configured for multiple threads. The Exchange OV/VM Connector supports only one thread.



RESOLUTION
Contact your local VM administrator, who has access to the host mainframe.  Open the RSCS configuration file. Ensure that the STREAMS or ST parameter is set to 1. For example:

PARM RSCSLINK BUFF=3072 ST=1 TA=0

The default for RSCS communications between OV/VM systems is for multiple threads. You must restart the RSCS system for any changes to take effect.



MORE INFORMATION
The following information is documented in Microsoft Exchange Connector for IBM OfficeVision/VM Installation and Configuration in Chapter 2:

RSCS PARM Statement
The following table describes the PARM statement you need for the link.

NOTE: Do not set the RLPASS, RNPASS, TLPASS, and TNPASS parameters in this statement. If you do, the connector cannot sign on to the host. You can allow other parameters to default.
