Build toolkit on z/OS using 64 bit java

Alex Akilov (1211924) | asked Apr 22 '14, 1:54 p.m.
Hey guys,

I'm getting the following error when running a build on z/OS: java.lang.UnsatisfiedLinkError: RTCzMVSExec64 (Not found in java.library.path).  Don't recall a configuration step that required updating LIBPATH anywhere.  We have configured with JAVA_HOME pointing to the 64 bit Java install dir and BLD_TOOKIT pointing to the <jazzInstall>/buildsystem//buildtoolkit  folder.

What are we missing?

 Hi Alex,

Check that you have the file in your buildtoolkit directory, and that its permissions are set correctly ('chmod 755' plus 'extattr +p'). For more detail, see

Here are the permissions (i.e. no writes for group and other but not sure why those would be needed):
 -rwxr-xr-x  -ps-  1 OEDFLTU  UUCPG     106496 Aug  5  2013

Looking in the EEBAW labs materials it does mention that the build user ID needs to have LIBPATH set to point to the buildtoolkit folder.  If so, seems the sample that ships with the product should include something like:


Am I right?

 Hi Alex - 

can you open a work item and attach your build log for us to take a closer look?  
Are there any ICH408I type RACF errors at the time you attempt the build?
Is this an SMP/E installed RTC toolkit and which release?


Alex Akilov commented Apr 23 '14, 5:28 p.m.

Bruce, created Work item 313481.  Note that setting LIBPATH solved the issue (RACF wasn't the culprit).  We have 4.0.4 build toolkit installed (SMP/E).
