Look up DB2 error codes: the fast way

I have to admit that I’m not a big fan of DB2 although there is not much wrong with the database itself. I have more problems with the far-from-perfect tooling.

One of the things that keep annoying me are the cryptic error messages including an even more cryptic SQL error code that DB2 returns. Normally I look up the error code in the DB2 Information Center, but if you need a shorter and faster way to get at least a short explanation of what an error code means, you can use the following SQL query:

VALUES SQLERRM(-161)

Result:

1
------------------------------------------------------------------------------------------------------
SQL0161N  The resulting row of the insert or update operation does not conform to the view definition.

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
