ATTENTION: Customers using Connect:Direct for UNIX v4.1.x!
This product will reach END OF SUPPORT on September 30 2017.
IBM Support will stop supporting this product after this date. See the following announcement.
Please plan your upgrades accordingly!
There are significant differences between CDU v4.1.x and CDU v4.2.x. The main differences are the introduction of a Keystore database for managing certificates, using IBM Key Manager to manage the Keystore, and configuring Secure+ to work with the Keystore.
In Secure+, the TLSv1.2 Security protocol and associated ciphersuites will be available to use with the new version.
Support for SHA2 private certificates will also be available.
Before upgrading, you will want to take a snapshot of your current CDU installation for safe keeping.
During the upgrade, there is an option to backup the original installation, make sure you choose to do this.
You will also be prompted for a password for the Keystore database. This is a non-recoverable password, so don't lose or forget it. It will be needed every time you work with certificates in the Keystore.
The upgrade process to CDU v4.2.x goes smoothly. Any existing certificates and Secure+ configurations will be automatically imported into the new Keystore and new Secure+ configuration.
Any Secure+ connections using the STS Security Protocol will not be migrated to CDU v4.2.x as the STS Protocol has been decremented from the product.
If you have not already done so, it would be very beneficial and helpful to install the X11 Server libraries to facilitate the use of the GUI interfaces for the IBM Key Manager Tool and the Secure+ Admin tool. See the Release Notes for more information about what libraries to install.
The current versions of CDU are as follows. The iFix number will change as new updates are released.
Please read the “Release Notes” for the current hardware and software requirements.
The current version of CDU for Linux running on RHEL is supported only on RHEL v6.4 or newer, or RHEL v7 - any point release. (The online Release Notes are being updated to reflect this requirement)
These Fixpacks are available from IBM Support Fix Central and can be used to do an upgrade from CDU v4.1.x. The upgrade instructions are given in the "iFix Installation Instructions" document.
