Reinstalling a Software Product

If you attempt to install the product level of a software product that is already installed on the system, then you are reinstalling the product. A product can be reinstalled at the same, earlier, or later level (level refers to the version.release.modification.fix level of the product).

Reinstalling at the Same or Earlier Level

You can reinstall a product at the same or earlier level using either Web-based System Manager or the command line (this is called force-installing).

To Reinstall Using Web-based System Manager

1. To start the Web-based System Manager Software application, enter: wsm software . The Software container displays.
2. Select Software from the menu.
3. From the pulldown, select New Software (Install/Update).
4. Select Install Additional Software (Custom).
5. On the Install Additional Software dialog, click Advanced.
6. On the Advanced Options dialog, select the Overwrite same or newer versions option.

   Note: If you are reinstalling from an earlier level only, you must deselect the option to Filter out language filesets and previous versions.

To Reinstall Using the installp Command

To reinstall at the same or earlier level from the command line, use the installp command with the force (-F) option. If you must use the force option, enter the smit install_selectable_all fast path and choose only those product filesets you want to install. You can only select the base level of a product because updates cannot be installed during a forced installation. After completing the forced reinstallation of a product, you can update the product by entering the smit install_fileset fast path.

Reinstalling at a Later Level

You can reinstall a product at a later level using either Web-based System Manager or the command line.

To Reinstall Using Web-based System Manager

1. To start the Web-based System Manager Software application, enter: wsm software . The Software container displays.
2. Select Software from the menu.
3. From the pulldown, select New Software (Install/Update).
4. Select Install Additional Software (Custom).
5. Use the dialog to complete the task.

To Reinstall Using the installp Command

To reinstall at a later level from the command line, enter the smit install_latest fast path (without specifying the force option) and the updates will also be installed.
