PCA – Patch Check Advanced

If you are in charge of administering Solaris machines, you might want to take a look at PCA – Patch Check Advanced.

From its Web page:

pca is a perl script which generates lists of installed and missing patches for Sun Solaris systems and optionally downloads and installs patches. By default, if run without any option or operand, pca shows a list of all patches which are not installed in their most recent revision.

The output of the pkginfo, showrev and uname commands is used to gather information about the system. Sun offers a patch cross-reference file called patchdiag.xref which contains information about all available patches. This file is downloaded by pca automatically to /var/tmp/ and kept up-to-date. If the file exists and is not writable, pca uses it and won’t try to update it.

The beauty of pca lies in its simplicity and effectiveness. I’ve always found Solaris patching procedures to be complicated, hard to automate and well beyond patching of GNU/Linux systems. Even Windows and Mac OS X systems are easier to patch than Solaris, in my opinion. I think that pca pretty much closes the gap. Kudos to Martin Paul for creating and maintaining pca.

  1. Excellent resource.

    Even considering that Solaris has improved quite a lot, regarding patching and updating tasks, this type of tools are always welcome by sysadmins. Simplicity in administration, as you say, is a rare and delightful feature, not very common nowadays đŸ™‚

  3. whether TDS on rent in case of joint property where the owner of the property is 50-50%, and if the the combined rent exceeds the ceiling but not the individual rent, in that case is it necessary to deduct TDS on rent at source. Eg. if the total rent received by the joint landlords is Rs.18500.00 per month, do we have to deduct tax on rent at source during the current financial year i.e. 2011-12.
