SYMPTOMS
When you attempt to invoke a non-queued Win32 autostarted APPC or CPIC application configured to run on the SNA Server Windows NT and Windows 95 client computer, the following error may occur:
SNA client-side traces reveal that the application is invoked and correctly posts a RECEIVE_ALLOCATE (or CMACCP) before the dynamic load request for the TP arrives, though the RECEIVE_ALLOCATE (or CMACCP) never completes and the above dynamic load timeout error is logged.
CAUSE
Due to changes implemented within SNA Server 2.11 (and later versions) to support IBM CICS for Windows NT, invokable APPC TPs which require non- queued operation may occasionally experience dynamic load timeout problems along with Event 60.
RESOLUTION
An update to the SNA Server 3.0 Windows NT and Windows 95 client is available to correct this problem (post-SP1). With this update applied, a new registry setting can be configured to disable this special support for the IBM CICS product
CicsSupport: REG_DWORD: 0
where:
0 = disable support for IBM CICS for Windows NT 1 = enable support (the default)
If the initial invokable TP is written as a Windows NT service, then the registry key value to add exists in:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/<tpname> /Parameters/
If the initial invokable TP is written as a Windows NT application, then the registry key value to add exists in:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/SnaBase/Tps /<tpname>/Parameters/
If the initial invokable TP is configured to run on a Windows 95 client, then the registry key value to add exists in
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/SnaBase/Parameters/TPs /<tpname>/Parameters/
where <tpname> is the APPC or CPIC transaction program name.
STATUS
Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0 Service Pack 1. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
