Error description
TCP/IP Clients hang when attempting to restore and/or retrieve large data files.
Local fix
The customer should code IUCVTCPIP in the ADSM MVS server option file and start the server.
Problem summary
**************************************************************** * USERS AFFECTED: All users of TCP/IP for MVS; HPNS and ADSM * **************************************************************** * PROBLEM DESCRIPTION: TCP/IP clients hang when trying to * * Write or Send large data files. * **************************************************************** * RECOMMENDATION: none. * **************************************************************** An ADSM client hangs when attempting to restore a file. The hang occurs when in the middle of issuing receives for the file. The following ADSM error messages are associated with the failure: ANR5092E, ANR0480W, and ANR0482W. The TCP/IP packet trace showed that the client had acknowledged the transmission, but the process hung after transmission.
Problem conclusion
Macro EZACACB was changed to ensure the ACB initial Write flag is set correctly when processing a socket WRITE or SEND request. * Cross Reference between External and Internal Names
Temporary fix
This problem may be circumvented for ADSM by adding the undocumented option IUCVTCPIP to the ADSM/MVS Server options file. This option is intended to be used only at the request of IBM service and should be removed when the formal fix for APAR PQ03285 is installed. The syntax is simply to add a line to the end of the ADSM server options file containing only the keyword with no parameters, example: IUCVTCPIP No changes are required for the ADSM Clients. ********* * HIPER * *********
