When using the DBCA tool under Oracle 11gR2 64-bit on Windows 2008, and trying to specify ASM as the file storage, the following error is encountered:
“grid infrastructure or clusterware home not found”
The DBCA tool must be run as Administrator, even if the account you are using is already an Administrator privileged account.
If you launch DBCA from the command line, the CMD executable must be launched with the Run As Administrator option.
In this blog post, we are going to install Oracle Enterprise Manager 12c (220.127.116.11) on CentOS 6.3 64-bit using VMware Workstation 8.
Oracle Enterprise Manager (OEM) has been around since the 8.0 days. What started out as a fairly light-weight client-server GUI tool for managing database functions has morphed into a complex and brittle mess of poor interface design and sloppy coding.
Although 12c is a step up from the god-awful OEM 11g, the hapless Oracle DBA is still left with a muddled mess of an interface and a tool that is likely to cause more headaches than it solves.
