Operating systems

The operating systems that CICS® Transaction Gateway supports.

CICS TG for Multiplatforms runs on:
  • IBM® AIX®
  • Linux® on Intel
  • Linux on POWER® (Big Endian)
  • Linux on POWER (Little Endian)
  • Red Hat Enterprise Linux (RHEL)
  • Linux on z Systems®
  • Microsoft Windows

CICS TG for Multiplatforms and CICS TG Desktop Edition are only supported on 64-bit operating systems.

Note:
  • The 64-bit ncurses-lib (libncurses.so.5) Linux package is a prerequisite to start the Gateway daemon.
  • The 64-bit ncurses-lib (libncurses.so.6) Linux package is a prerequisite to start the Gateway daemon in IBM Linux on Power LE.
  • CICS TG uses libncurses v5. So, you must create softlinks to libncurses v5.
    • Create a softlink from libncurses.so.6 to libncurses.so.5.9:
      ln -s /lib64/libncurses.so.6 /lib64/libncurses.so.5.9
    • On RHEL 9, create a softlink from libncursesw.so.6.2 to both libncurses.so.5 and libtinfo.so.5:
      ln -s /lib64/libncursesw.so.6.2 /lib64/libncurses.so.5
      ln -s /lib64/libtinfo.so.6.2 /lib64/libtinfo.so.5
