zCX Docker Enhancement Request: Native Support for Pre-Startup Network Dependencies (NFS over AT-TLS)

Remove home directory of removed LDAP user

When a ZCX user is removed from LDAP it's home directory is not removed. There is no way to remove this. So you end up with home directories which correspond to old users. I think there must be a solution created for this. When using ZCX local use...

Add proxy settings to the Z/OSMF workflow for zCX

Hi, For a user to be able to download containers from the outside world from a zCX SSH prompt when you are behind a proxy they all must run "export http_proxy=..." commands. I think that is quite awkward. Especially since you have to do it every t...

Allow modification of the core_pattern in zCX.

Currently the core_pattern (/proc/sys/kernel/core_pattern) in zCX contains string “|/usr/sbin/event-daemonCoreDump.sh %e %p %s” even though /usr/sbin/event-daemonCoreDump.sh is not supplied by IBM. This prevents capturing core dumps in containers.

Allow a custom subnet mask for zCX OpenShift nodes

Currently, only the default subnet mask 255.255.255.0 can be used for zCX OpenShift nodes. We need to be able to configure a custom subnet mask to fit our network configuration.

Multiple Image Registry for zCX

This is a request for Enhancement in z/OS Container Extensions (zcx or classic zCX). zCX currently allows only one secure image registry & its certificate to be specified in its configuration. If we want to change the image registry, we need t...

Support Compression for zCX-VSAM Files

We want to compress the data from zCX at runtime to minimize the I/Os and the used space on DASD. For Pervasive Encryption it is recommended to compress data before encryption. For zFS VSAM-LDS Files it is possible to compress by using zfsadm comm...

Create a zCX Container for Tivoli Warehouse Proxy and Tivoli Summarization and Pruning Agent

We currently run the Tivoli Enterprise Portal and we use the Data Warehouse. IBM has created a zCX container image for the Tivoli Enterprise Portal. It would be great if we could also get containerized versions of other Tivoli monitoring agents - ...
