Chapter 3. Recognizing System Problems
This chapter describes common OpenShift Enterprise system problems, and provides information to troubleshoot and resolve these issues.
3.1. Missing Repositories
If you are having issues installing the required OpenShift Enterprise software packages, verify that you have the correct YUM repositories configured. If you are using the classic RHN subscription, you must enable the correct channels. Both the broker and node host installations require a Red Hat Enterprise Linux 6 subscription.
Furthermore, each type of installation requires the designated RHN channels and repositories. Therefore, if you are installing a broker host, RHN channels and repositories that are specific to the broker host must be enabled. Similarly, repositories and RHN channels specific to the node host must be enabled when installing a node host.
The following table shows the required repositories for OpenShift Enterprise, with a brief description of each.
| Name of Repository | Description |
|---|---|
| Red Hat OpenShift Enterprise Infrastructure | Broker / BIND / Mongo hosts |
| Red Hat OpenShift Enterprise Application Node | Node hosts |
| Red Hat OpenShift Enterprise Client Tools | Client hosts |
| Red Hat OpenShift Enterprise JBoss EAP add-on | Included with EAP support purchase. See note below. |
| Red Hat OpenShift Enterprise Application Platform | Included with EAP support purchase. See note below. |
| Red Hat OpenShift Enterprise Web Server | Included with bundle purchase. See note below. |
Note
These repositories are required on node hosts for JBoss cartridge support.
Important
Configuring the wrong RHN channels or repositories can result in a failed installation.
