|This task explains how to install a service pack from an archive file, as an alternative to the traditional methods involving installing the service pack from the CD-ROM or using the Start command.|
|An archive file is an uncompressed file on
UNIX, built by a command provided. The compressed file contains
installation files containing differences with respect to an earlier
installed level of the same release of the same software configuration. A
level can be either a GA or a service pack.
For example, you can build an archive file containing the differences between level V5Rn GA and V5Rn SP2 (even if you installed V5Rn SP1 in between).
Building and Installing the Archive
|You first need to install several software
levels (belonging to the same release) on the source computer. In our
example illustrated below, we installed levels V5Rn GA, V5Rn SP1 and V5Rn
SP2, and committed the service packs. On the target computers, only the
V5Rn GA level is installed.
You use the
|The advantages of this type of installation
|Note that installing a service pack from an archive file always commits the service pack automatically. Make sure that the previously installed service packs on the target computer have been committed before installing the archive. Furthermore, you can only use this method if the configurations/products on both the source and target computers are identical.|
|The traditional methods of service pack
installation and the use of the
|1. Log on as an root onto the source
2. Perform, for example, the following installations:
where "B0n" is the level V5Rn and "OS" is:
4. To build an archive file based on
the differences between the V5Rn GA and V5Rn SP2 levels, for example, run
The full command syntax is:
Note that there are two distinct operating modes:
The archive built on UNIX is not compressed.
The service pack installed your computer, and
used as the basis for comparison with a previous level, must be committed
beforehand. If not, the
to create the compressed archive file
6. Copy the compressed archive file
Keep in mind that the target computer must be running the same Version 5 configuration/products as the source computer on which the archive file was built.
7. Stop all running Version 5 processes on the target computer before proceeding.8. If you compressed the archive file earlier, uncompress it by running the command:
to obtain the archive file
9. Install the archive file
On UNIX, go to the directory:
then install the archive by running the command:
The service pack is committed automatically.
Note: The tar command is not enabled for files greater than 2 GB an AIX.
10. Start a session to check the service pack has been correctly installed.
