Installing and configuring the PAX edition

Planning for installation requires three main tasks: ensuring you have the correct hardware and software installed, choosing the right default location, and setting up the environment variables accordingly. To download the latest PAX edition, visit IBM® Open Enterprise SDK for Go product page.


Hardware requirements
  • z16
  • z15™
  • z14®/z14 model ZR1
  • z13®/z13s®
Software requirements
  • z/OS® UNIX System Services enabled on z/OS 2.5.0 or later
    Note: Go programs need to bind to the LE runtime services using the c89 utility under the z/OS UNIX System Services environment. You may encounter the following error if your c89 utility was not set up correctly:
    FSUM3052 The data definition name SYSLIB cannot be resolved. The data set was 
    not found. Ensure that data set name CEE.SCEEBND2 is specified correctly.        
    open /tmp/go-build794287247/b001/exe/hello: EDC5129I No such file or directory.
    For details on how to fix this error, see Cannot locate CEE.SCEEBND2 data set.
