Finding And Deleting Old Files (on Unix and Windows)

I needed to write short scripts to delete old files on a Windows Server. It’s a very easy task on UNIX flavors but the limited capacity of Windows command line made me worried. You can use a simple “find” command to find old files on UNIX. For example, the following command will be enough to find and delete files older than 7 days:

find /folder/ -type f -mtime +7 -exec rm {} +

My Presentation on Oracle Solaris Zones Capacity Management

So one more successful annual conference of All India Oracle Users Group (AIOUG) happened on November 9th and 10th at Hyderabad, India.

Earlier I used to attend Oracle database sessions at AIOUG but this time AIOUG board had done a remarkable job by extending the coverage to Solaris topics. Obviously as (more...)

What If I Want to Update Just Java?

| May 28, 2013

Sometimes all you want to update is Java, and not your entire Oracle Solaris environment. But Java is packaged as part of the Oracle Solaris systems software, and Oracle recommends that you update all the system software at once, since it was tested together.

What can you do?

New White Paper Compares SPARC/Solaris to Power/AIX Costs. Guess Who Wins?

| May 15, 2013

One thing that's been clear since the launch of Oracle's new Sun SPARC T5 and M5: it got IBM's attention. Judging from their response, they seem to be... I'm going to go with concerned.

And as I've said before, I don't blame them. A company with a long history behind (more...)

Should I Disable RPC Devices to Increase Oracle Solaris Security?

Recently someone asked me what Oracle's official position was regarding disabling RPC devices to increase security on Solaris 10 and Solaris 11.

Oracle has no official position on securing your Oracle Solaris 11 systems; however, I recommend the standard security best practice of removing network facing services that are (more...)

How to Build A Cloud for Family and Friends Using Oracle Solaris 11

When we talk about cloud, we tend to focus on The Cloud. Enterprise. Government. Scalable. Fast. Big. Bigger. Fastest. That's all wicked impressive, but it's not something I can do on a rainy Saturday afternoon. Now, I like and use Dropbox. There are other easy-to-use cloud services out there similar (more...)

In response to the release of Oracle's SPARC T5 and M5 chips, which are dramatically faster than those of IBM, IBM responded by saying that speed was not as important as other qualities. Forbes begged to differ:

Continuing on the performance theme: Oracle's SPARC T5-8 server is now the world's fastest single server for Oracle Database.  In a server-to-server comparison, T5-8 has a sevenfold price advantage over a similar IBM Power 780 configuration for database.

This is a perfect example of what we can do by (more...)
