We would like to move one of our MQ applications which currently runs under AIX to run on OS/390 under Unix System Services (USS). On the OS/390 LPAR, we already have a QMGR. Would this application be able to talk directly to the QMGR on OS/390, or would we need to have a QMGR running under USS or possibly some client software on USS?
I am having trouble visualizing how this would work, I don't know how USS and OS/390 interact. Has anyone done this? Any ideas on the best path to do this?
Thanks!

Hi,
No problem. USS runs as a shell on a MVS LPAR similar to TSO. Think of JES2, TSO & USS being siblings (or peer tasks) on the LPAR.
Therefore, if you have a queue manager on the same LPAR as the USS shell, then compile and link your program. It will run locally connecting to the queue manager.
Hope that helps.

| Thanks for your reply Roger ! I appreciate it. I was kind of thinking that would be the case, but haven't had a chance to try it, yet.... |

Hi,
How do I complie a MQSeries program under OS/390 under uss?
Where are the shared libraries and include files under uss?
Thanks
Tom. |

Hi folks,
I've created a small shell script to do the compile, (I hope the charater conversion will work), you have to change the <hlq> to the values that your system programmers have decided.
By the way offcause you also have to have access to USS..
Anyway this is my setup for running the C++ compiler...
| Code: |
if [ $# = 0 ]; then
echo "C++ compiler invocation cmd, used for MQSeries,"
echo "usage buildc++ modulename"
echo "no module was supplied..."
echo "build++ is terminated"
else
export STEPLIB=<hlq>.SCBCCMP
export _CXX_EXTRA_ARGS=1
export _CXX_CXXSUFFIX="cpp"
export STEPLK1="//'<hlq>.SCSQDEFS(IMQS23DM)'"
export STEPLK2="//'<hlq>.SCSQDEFS(IMQB23DM)'"
export STEPIN1="//'<hlq>.SCSQC370'"
export STEPIN2="//'<hlq>.SCSQHPPS'"
echo "Compiling "$1", loadmodule is placed in:"$HOME"/bin"
c++ -o $HOME/bin/$1 -I "$STEPIN1" -I "$STEPIN2" $1.cpp "$STEPLK1" "$STEPLK2"
fi
|
I hope it might helpt you get get up and run under USS, take also a look in the "MQSeries using C++" manual....
Just my $0.02

Hi,
Thanks for the latest reply, sorry for not asking such a trival question, however I have another:
The compling of the application is fine, however the linking stage I get the following:
"
IKJ56228I DATA SET SYS1.SCSQDEFS NOT IN CATALOG OR CATALOG CAN NOT BE ACCESSED
FSUM3053 The data definition name C8921 cannot be resolved. The data set was not
found. Ensure that data set and member name SYS1.SCSQDEFS(IMQS23DM) are specified correctly.
"
Does this just mean that I have not got user access to this deck. Or is there something more, e.g. something not support in OS/390 MQ version 5.2?
I can only access the system in USS mode.
Thanks in advance.
Regards
Tom |

Hi,
I now have another issue! What dataset deck do I need to include to link with the MQSeries C libaries? I am assuming it is MQM, but this does not seem to be correct.
Is there a manual with compling OS/390 under USS for C? Or does anyone have a sample makefile?
Thanks in advance
Tom. |

Hi,
Getting the development environment setup under USS is a pain in the *ss.
If the OS/390 - USS admin person has not setup the environment variables then you will need to add the following to your .profile file:
| Code: |
# These lines set up the compile environment for Commom usage C programs
# Change the _CC_ variables to _C89_ for standard C
export DSNAOINI=/jh/tax/cli/cli.ini
export _CXX_STEPS=-1
export STEPLIB=SYS3.CEE.SCEERUN:SYS3.CBC.SCBCCMP:SYS3.CBC.SCLBDLL:SYS3.MQM.SCSQAUTH:SYS3.MQM.SCSQANLE
export _CXX_EXTRA_ARGS=1
export _C89_EXTRA_ARGS=1
export _CXX_CSYSLIB=SYS3.CEE.SCEEH.H:SYS3.CBC.SCLBH.H:SYS3.MQM.SCSQC370
export _CSS_PSYSIX=""
export _C89_CSYSLIB=SYS3.CEE.SCEEH.H:SYS3.CBC.SCLBH.H:SYS3.MQM.SCSQC370
export _CXX_LSYSLIB=SYS3.CEE.SCEELKEX:SYS3.CEE.SCEELKED:SYS1.CSSLIB:SYS3.MQM.SCSQLOAD
export _C89_LSYSLIB=SYS3.CEE.SCEELKEX:SYS3.CEE.SCEELKED:SYS1.CSSLIB:SYS3.MQM.SCSQLOAD
export _C89_PSYSLIB=SYS3.CEE.SCEEOBJ:SYS3.CEE.SCEECPP:SYS3.CBC.SCLBDLL
|
Once you have that done then you can use a makefile like the following:
| Code: |
# makefile for test programs under USS
TEST_SRCS := \
tstsrv1.c \
tstsrv2.c \
tstsrv3.c
OBJECTS = $(TEST_SRCS:%.cpp=%.o)
DEBUG = -Wc,"FLAG(E)"
INCLUDES = -I. -I../../mmsg/inc
COMMONFLAGS = $(DEBUG) -Wc,dll -DUSS -Wc,"langlvl(extended)"
CXXFLAGS = $(INCLUDES) $(COMMONFLAGS)
LIB_DIRS = -L. -L../../lib
LINK_LIBS = ../../lib/libwxyz.x "//'SYS3.MQM.SCSQLOAD(CSQBSTUB)'"
all : $(OBJECTS)
c++ $(CXXFLAGS) -o $@ -c $<
c++ $(CXXFLAGS) $(LIB_DIRS) -o ../go/tstsrv1 tstsrv1.o $(LINK_LIBS)
c++ $(CXXFLAGS) $(LIB_DIRS) -o ../go/tstsrv2 tstsrv2.o $(LINK_LIBS)
c++ $(CXXFLAGS) $(LIB_DIRS) -o ../go/tstsrv3 tstsrv3.o $(LINK_LIBS)
echo 'Build Complete'
clean :
@rm -fr *.o |
Hope that helps.

After a bit of modification to sample Makefile the application has complied and linked!
Thank you all again, great to see a good online community.
Regards
Tom. |
