GSKit version compatibility

The stash files that you generate with IBM MQ Version 9.0.0, Fix Pack 1, or later must be compatible with any applications and other IBM MQ installations.

For the version of GSKit for IBM MQ Version 9.0.0, Fix Pack 1 or later, the stash file format that is used when you generate an .sth file to stash the key database password is different from earlier versions of GSKit. Stash files that are generated with this version of GSKit are not readable by earlier versions of GSKit. To ensure that stash files that are generated with IBM MQ Version 9.0.0, Fix Pack 1, or later, are compatible with the applications and other IBM MQ installations, we must update to a version of IBM MQ that contains a compatible version of GSKit. The following fix packs contain a compatible version of GSKit:

• V7.1.0.8
• V7.5.0.8
• V8.0.0.6
• V9.0.0.1

If we cannot update the applications or other IBM MQ installations, we can request a stash file format that is compatible with an earlier version. When we use the runmqakm or runmqckm commands with the -stash or -stashpw option, include the -v1stash command line parameter. We cannot use the strmqiqm GUI to generate a stash file that is compatible with an earlier version.
