You can override the default, automatic setting of interprocess communication (IPC)
kernel parameters that normally takes place when the Db2
Warehouse service is initialized and
set the kernel parameters manually.
About this task
When you configure Db2
Warehouse for isolated deployment, a limited privileged SCC is
automatically deployed.
Procedure
- Patch the Db2whservice CR with the privileged setting by running the following
command:
oc patch Db2whservice db2wh-cr --type merge -p '{"spec":{"privileged":false}}'
- If you have the Db2oltpservice CR or the Db2aaservice CR running in your cluster, patch
those services by running the following commands:
oc patch Db2oltpservice db2oltp-cr --type merge -p '{"spec":{"privileged":false}}'
oc patch Db2aaserviceservice db2aaservice-cr --type merge -p '{"spec":{"privileged":false}}'
- Wait for the Db2
Warehouse service to be in
Completed
state. To get the state value, run the following
command:
oc get Db2whservice db2wh-cr -o jsonpath='{.status.db2whStatus} {"\n"}'
- Deploy the Db2
Warehouse
instance.
