A necessary part of a cluster is the cluster interconnect: the private network between the cluster nodes. This component is critical for both reliability and scalability, and configuring it for fault tolerance and capacity is a matter of burning importance for the DBA and his System Administrator (not to mention the end users). One question is, should this be managed by the operating system or by Oracle?
Please find the installation steps for ORACLE 12C Database.

In earlier releases, running a shell script from the Scheduler was awkward. Oracle has realized this, and introduced a new job type in 12c that makes it simple.
There are three restrictions on indexing and partitioning: a unique index cannot be local non-prefixed; a global non-prefixed index is not possible; a bitmap index cannot be global. Why these limitations? I suspect that they are there to prevent us from doing something idiotic.

When I was doing a research on Oracle Database creation, through DBCA, last week, I came across a very interesting scenario which I couldn’t stop sharing with you :)
I have a cluster of machines (don’t confuse it with a RAC cluster but just a group of machines required for my application deployment) with 22.214.171.124 installed and a Database instance running.
I got a requirement to remove everything accumulated in the machine as a result of the Oracle installation and the Database creation: The installation directories, the datafiles, oratab entries etc…
After removing all th
Matthew Morris (who makes many constructive and knowledgeable contributions to the forum) has written a series of study guides for the OCA/OCP exams. I asked him if I could have a copy of one to review. The result: it's very good. This is a copy of the review I put up on Amazon.
The other day, I was asked how to move a table from one schema to another. The answer, as we all know, is "you can't do that: you have to create a new table as a copy of the old one, or use export/import. It will take a long long time." Not true.
