Grid/CRS AddNode or runInstaller fails with NullPointerException

Posting this here mostly to archive it, so I can find it later if I ever see this problem again.

Today I was repeatedly getting this error while trying to add a node to a cluster:

OSP #3a: Build a Standard Cluster Platform

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.

We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch (more...)

Chicago Oracle User Community Restart

This is how you can make bulk property changes to a large group of targets in (more...)

Readable Code for Modify_Snapshot_Settings

It annoyed me slightly that when I googled modify_snapshot_settings just now and all of the examples used huge numbers for the retention with (at best) a brief comment saying what the number meant. Here is a better example with slightly more readable code. Hope a few people down the road (more...)

Largest Tables Including Indexes and LOBs

Just a quick code snippit. I do a lot of data pumps to move schemas between different databases; for example taking a copy of a schema to an internal database to try to reproduce a problem. Some of these schemas have some very large tables. The large tables aren’t always (more...)
