Installing a JVM

The CICS® Transaction Gateway requires a supported version of Java™. A JVM is installed with the CICS Transaction Gateway installation.

The default behaviour of CICS Transaction Gateway is to use the JVM installed with the product or you can configure a supported JVM that has been installed independently of CICS Transaction Gateway. See Specifying the JVM to configure the JVM to use.

The product download files for CICS Transaction Gateway for Multiplatforms provide JVM installers for use with remote Java applications.

The JVMs shipped with CICS Transaction Gateway may become out of date and potentially vulnerable. You should regularly check for later service releases of Java which might be available for download from FixCentral and should be used where available to ensure reliability, security, and compatibility with the latest features. For more information, see Installing and uninstalling fix packs.
