Q: To install software, do I need to create a bundle?
A: No. You can create bundles if you want, but normally, administrators just select and install the filesets and packages without creating bundles.
Q: How do I know what part of a package to install in (root) /, usr or share?
A: You don’t need to worry about this. If you use SMIT or the installp command, the files will install in the correct location.
Q: Why would I want to install my software in the Applied State?
A: When it is in the applied state, the new version of the software is active but the old version is “archived” on the hard drive. If you start to test the new version and you don’t like it for whatever reason, you can reject it and the old version is unarchived and replaces the new version. This lets you more easily back out of a new software install.
Q: Applied sounds good! Why would I ever install directly to the committed state then?
A: Keep in mind that applied holds a copy of the old version as well as the new version. You must have the disk space to hold them both. If you don’t have enough disk space to do this, your only option is to install to the committed state. Also, if you have software in the applied state, you cannot install other version of the same software in the applied state. You must first commit the previously applied version. Lastly, if this is the first time installing this software product, it will automatically be installed as committed. If there isn’t an old version, there is no reason to be in the applied state.
Q: How do I install a fix?
A: You can use the instfix command or use SMIT. If you use the instfix command you can type: instfix -k IX38794 -d /dev/rmt0.1 The -k is the keyword, in this case the APAR (or fix) number. The -d is the device where the fix resides. In this case, the device is a tape device. If you want to check to see if a fix is installed already, you can use instfix also: instfix -i -k “IX38794”
