zCX: Make docker cli available as MODIFY command to the STC

Currently, we've to login to zCX to issue "docker" commands like docker logs to zCX. In an early phase like POC / testing this is no problem. But as we're continuing / have the first production applications running, Operators also have to work wit...

z/OSMF Workflow Syntax Check for input variables

Currently, z/OSMF seems to not be able to check input fields for the correct syntax. In case of wrong input fields, z/OSMF just accepts the input and continues. This is even worse in case of e.g. provisioning a black box like zCX. For example: zCX...

zCX: Provide Sysplex Distributor Support for High Availability

Currently zCX only supports Dynamic VIPAs, no Sysplex Distributor support is available. In case of a Docker Swarm, or even a Single zCX Container within one zCX, there is a timing window in that the application within the Container is not availabl...

Unable to connect to z/OS Container Extension(zCX) from the WAN

The zCX default bridge subnet 172.17.0.0/16 causes conflicts (sometimes and always in our case) to the WAN workstations IP addresses. We request an enhancement or user customisation to avoid subnet conflicts when identified.

zCX: Personal and technical Userids mustn't be in the same group / results in workflow failures / rerunability

The zCX workflow says for the SAF group to be specified during provisioning: "Specify an existing SAF group name to allow that group access to this IBM z/OS Container Extensions appliance instance directory. The provisioning user of this IBM zCX a...

sudo incidents should be reported

If a user, that is not in the sudo group tries to issue a sudo it looks like this: user@server:~$ sudo mkdir /test[sudo] password for user:user is not in the sudoers file. This incident will be reported. But as I was told in case TS004442144 this ...

Command to display zCX memory SWAP, DATA and ROOT space usage

There is no command to display how much memory the zCX started task is using, or how much space is being used of the ROOT dataset; determining usage of SWAP and DATA is also difficult.This is separate from the within-docker commands to display ind...

zCX Support combined LFAREA usage (2G/1M) if not enough LFAREA is available within one type

Currently, zCX supports the use of LFAREA. This reduces the overhead for TLB and increases performance for zCX. If zCX is configured to use LFAREA and there is not enough LFAREA available within one range (2GB, 1MB) then zCX falls back to 4K what ...
