RHEL 4: Find up2date command module / library dependencies

Q. I'm using RHEL 4.x as database server. How can I run the up2date command to find out what package will satisfy library / module dependencies via RHN?

A.Update Agent provides a complete system for updating the RPM packages installed on a Red Hat Enterprise Linux system. Both command line and graphical interfaces are included.

Update Agent has a quite a few configuration options, including but not limited to: installing packages after they are downloaded; downloading source RPMs along with binary RPMs; whether or not to upgrade packages where the default configuration file(s) have been modified, and more.

--whatprovides=<dependencies> option

Use the following syntax to query the RHN servers to resolve the comma separated list of dependencies. It will return a list of packages that will satisfy these dependencies:

up2date --whatprovides=<dependencies>

For example, if an error read as follows:

error: failed dependencies:
      libxyz.so    is needed by httpd
      libabc.so.1  is needed by httpd

To find out all libs or module dependencies in any of the package, enter:
# up2date --whatprovides=libxyz.so,libabc.so.1
Output:

packagename-1.15

Now just install packagename-1.15:
# up2date packagename
