IBM Business Monitor 8.0.1.2, Cognos BI and Unix - Dependencies Again

This follows on from an earlier post: -


I saw this exception: -

in cogserver.log during the startup of the Cognos Dispatcher, included as part of IBM Business Monitor 8.0.1.2.

I also saw this: -

2014-08-28 15:09:04.276 FATAL [m.cognos.pogo.reportservice.ProcessManager] metadataServiceHandler-MDSRVProcessManager-ProcessMgrThread: External Report Server process BmtMDProviderMain cannot be started java.io.IOException: Process BmtMDProviderMain failed to start properly.

in the pogo_2014_08_28.log file.

I started digging into the two exceptions.

Both relate to Cognos binaries, and the errors imply that there's something missing e.g. a dependency.

First of all, I wanted to locate the offending binary: -

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/cognos/SupClusterMember1
find . -name BIBusTKServerMain


which showed one copy.

When I try and execute this: -

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/cognos/SupClusterMember1/bin
./BIBusTKServerMain

I get this: -

./BIBusTKServerMain: error while loading shared libraries: libX11.so.6: cannot open shared object file: No such file or directory

However, there is a 64-bit version: -

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/cognos/SupClusterMember1/bin64
./BIBusTKServerMain

port=39164 pid=29992

I then dug further using the ldd command: -

In both cases, I was looking for Not Found exceptions ( ironically I took the above listings AFTER I'd solved the problem - see below ).

The Not Found exception indicates a missing library.

Initially, I thought that the solution was to add: -

export LD_PRELOAD=/lib64/libfreebl3.so

into the shell ( ~/.bashrc ) for the user that actually runs WAS - wasadmin in my case.

However, that was a herring rouge.

The actual solution was to add the missing dependent libraries. The main missing library, as per the exception: -

./BIBusTKServerMain: error while loading shared libraries: libX11.so.6: cannot open shared object file: No such file or directory

was libX11.so.6.

I did have the 64-bit version of this library: -

/usr/lib64/libX11.so.6
/usr/lib64/libX11.so.6.3.0

but NOT the 32-bit version: -

/usr/X11R6/lib/libX11.so.6
/usr/X11R6/lib/libX11.so.6.1

I installed XFree86-libs-3.3.6-20.i386.rpm to give me the 32-bit libraries; mainly because I didn't have access to the source Red Hat Enterprise Linux 6.4 ISO repository.

I'd also installed libstdc++, again 32-bit as well as 64-bit.

I am going to go back through the entire setup again, using a vanilla RHEL image, in order that I can document the end-to-end process.

Interestingly, I'm seeing the same Cognos Dispatcher ( Report Studio ) issue on AIX 7.1.

The solution appears to be the same.

On a PoC environment, where the Cognos Report Studio works OK, I do have libX11.a installed, as below: -

cd lib
ls -1 libX*

libX11.a
libXau.a
libXaw.a
libXcursor.a
libXdamage.a
libXdmcp.a
libXevie.a
libXext.a
libXfixes.a
libXfont.a
libXi.a
libXm.a
libXmu.a
libXp.a
libXpm.a
libXrender.a
libXt.a
libXtst.a


ls -al libX11.a

lrwxrwxrwx    1 bin      bin              28 Apr 29 13:16 libX11.a -> /usr/lpp/X11/lib/R7/libX11.a

lslpp -w /usr/lpp/X11/lib/R7/libX11.a

  File                                        Fileset               Type
  ----------------------------------------------------------------------------
  /usr/lpp/X11/lib/R7/libX11.a                X11.base.lib          File


ls -al /lib/libX11.a shows sym. link to /usr/lpp/X11/lib/R7/libX11.a

lslpp –w /usr/lpp/X11/lib/R7/libX11.a

X11.base.lib

I've asked our AIX admin to install the X11.base.lib licensed program, and will see where we get to tomorrow.

*UPDATE*

Yep, once the AIX administrator installed the missing LPP, the Cognos Report Studio worked a treat, as did the BusinessSpace Report widgets.

This is what the AIX box said: -

0509-022 Cannot load module /opt/ibm/WebSphereProfiles/AppSrv01/cognos/SupClusterMember1/bin/libCgs.so.
0509-150 Dependent module libX11.a(shr4.o) could not be loaded.
