CICS/TS 4.1 and Java

CICS’s support of Java gets better with each release – which means that a more current version of Java is needed each time a new release of CICS is installed. CICS/TS 4.1 requires the 31-bit version of Java 1.6 (at least SR3), which can be downloaded from the IBM web site.

If it is desired to get started with CICS/TS 4.1 before that version of Java is available, there is a workaround … Create a file called JAVA_INSTALL_OK in the JAVA_HOME directory. This file needs to contain just one line:


Be sure to flag the file as readable by CICS (e.g., chmod 644 JAVA_INSTALL_OK).
