APAR NUMBER: PJ41479 PRODUCT: z/TPF FUNCTIONAL AREA: MQI CLIENT SUPPORT SHIPPED IN PUT: 11 ABSTRACT: Applications which are using the WebSphere MQ client on z/TPF need a mechanism to wait for messages to arrive without requiring an ECB to be active. PACKAGE CONTENTS: Source Segments: (C) base/cntl/tpf_app_base.cntl (C) base/include/tpf/amqrfpha.h (C) base/include/tpf/cmqc.h (C) base/include/tpf/c_mqpr.h (N) base/rt/cget.mak (N) base/rt/cmqget.c (C) base/rt/cmqi03.c (C) base/rt/cqrreq.c Object Only Binaries: None. Configuration Independent Binaries: (C) base/lib/libCMQI.so (N) base/load/CGET.so (C) base/load/CMQ3.so (C) base/load/CMQI.so (N) base/obj/cmqget.o (C) base/obj/cmqi03.o (C) base/obj/cqrreq.o Support Files: base/lst/cmqget.lst base/lst/cmqi03.lst base/lst/cqrreq.lst base/lst/CGET.map base/lst/CMQ3.map base/lst/CMQI.map OTHER BINARIES TO BUILD: YES (C) <sys>/load/IPAT.so (C) <sys>/stdlib/libTPFSTUB.so (C) <sys>/stdload/TPFSTUB.so (C) <sys>/obj/ipat.o COMMENTS: Currently an ECB is required to remain in the z/TPF system if an application is using the WebSphere MQ Client on z/TPF to get messages from a remote queue manager if the MQGMO_WAIT option is specified and there are no messages on the queue. This can result in a large number of suspended ECBs remaining in the z/TPF system if there are many queues being serviced. A method is required that allows those ECBs to be exited and new ECBs created when a message arrives.
SOLUTION: The following functions have been added to z/TPF. - TPF_MQGET allows an application to request a message using the WebSphere MQ client to request a message from a remote queue manager and specify the application which should be activated when the message arrives. - TPF_MQGET_RESUME continues processing of a message that was requested by the TPF_MQGET function. In addition the __TPF_CLIENTONLY compiler option has been added which improves the performance of applications which are using only the MQ Client interface on z/TPF. COREQS: NO None. MIGRATION CONSIDERATIONS: YES Application programming interface (API) changes: TPF_MQGET and TPF_MQGET_RESUME have been added.
