tpcommit() is not doing commit for IBM mq message.
Hello
tpcommit() is not committing the IBM MQ message though it says commit is successful. Attached the logs for tpopen() and tpbegin()/tpcommit() logs.
Below is the flow of our clientApp code:
int main(){
if (tpinit(NULL) -1) {
std::cerr << "Failed to initialize Enduro/X Client: " << tpstrerror(tperrno) << std::endl;
return -1;
}if (tpopen() -1) {
std::cerr << "Failed to open Resource Managers via XA::::: " << tpstrerror(tperrno) << std::endl;
tpterm();
return -1;
}MQCONNX(MQ_Host, &connOpt, HCon, &CompCode, Reason);while(1) {
if(tpbegin(5, 0)) {
std::cerr << "Failed to tpbegin ::::: " << tpstrerror(tperrno) << std::endl;
tpterm();
return -1;
}
std::cout << "Successfully began XA 2 trns" << std::endl;MQMD md = {MQMD_DEFAULT}; /* Message Descriptor /
MQPMO pmo = {MQPMO_DEFAULT}; / put message optionspmo.Options = MQPMO_SYNCPOINT MQPMO_DEFAULT_CONTEXT;
md.Report = MQRO_EXPIRATION_WITH_DATA;MQPUT(HCon, HObj, &md,&pmo,msglen,msg,&CompCode,Reason); if(tpcommit(0)) {
std::cerr << "Failed to tpcommit ::::: " << tpstrerror(tperrno) << std::endl;
tpterm();
return -1;
}}MQCLOSE(HCon,&HObj,C_options, &CompCode, Reason);if(tpclose()) {
std::cerr << "Failed to tpclose ::::: " << tpstrerror(tperrno) << std::endl;
tpterm();
return -1;
}
tpterm();}

Hello,
Below is the answer for all your queries.
1) Can you please attach tmsrv-rm1.log?
Attached complete tmsrv-rm1.log.
2) Can you please attach full log file of clientApp? As looking on PIDs tpopen.txt was from other PID not the one in enduro_tpbegin_tpcommit.txt .
Attached full log file.
3)Did you start the clientApp with proper NDRX_CCTAG="MQ_TAG" ./clientApp env?
Yes. You can cross check the same in the logs attached.
4) Do you have access to IBM MQ logs? Are there any useful infos?
Yes, We have access, but there is no useful information.
5)ndrxconfig.xml does not use "<rmname>MQSeries_XA_RMI</rmname>" this tag.
Tmsrv loads the XA switch provided by shared library.
Yes, This was not required, included just to check. Anyhow we have removed it.
