OpenShift 4 Upgrade Paths

For OpenShift 4, the upgrade paths are kept in the cincinnati-graph-data repository as YAML files and then exposed via an API.

There is a Red Hat Solution describing how this data can be queried via and how you can use this data in your automation:

$ curl -sH 'Accept:application/json' '' | jq .

While this data is quite helpful for automation (the Solution also describes helpful queries), it is not very nice to look at the raw data. If you are looking for a graphical presentation of that data, you should check out this wonderful website that is maintained by a Red Hat colleague with hourly generated data:

ORA-01722 during upgrade 10.2 to 11.2

As we are migrating the last databases from Oracle 10gR2 to the latest release, there are some errors that we stumbled upon along our way. For example, when we tried to upgrade one particular database, during the upgrade the following error was thrown:

  2   WHERE
  3    value = 'TRUE' and parameter = 'Oracle Database Vault';
ERROR at line 1:
ORA-01722: invalid number
