2.3 Adding or removing components

After installing IDS 11, you might need to alter the installation by adding or

removing IDS components. For example, you might need to add locales for new

users or choose to begin using OnBar rather than ontape for backups.

To add or remove components, use the same installer that you used for the

previous installation. However, because the installer finds the product already

installed, there are different choices. After launching the installer and choosing

the product that you want to affect (on the second window), you see the choices

shown in Figure 2-6.

You can remove or uninstall components or the entire product; you can reinstall

damaged files; or you can change what is installed by adding or removing (or

both) components.

For the example depicted in Figure 2-6, we chose to Modify the installation.

When you click Next, the window shown in Figure 2-7 on page 63 appears.

Compare this to Figure 2-3 on page 48. The same choices are available in both

cases.

Figure 2-7 Component selection on reinstallation

You can change the selections by adding or removing them. For example, you

can add the High-Performance Loader. When you click Next again, the installer

makes the changes that you want. Therefore, the source directory must be

available to add components. You might want to copy that directory to a CD or

DVD so that it does not take disk space on your system. Then, the reinstallation

can be performed directly from the CD or the DVD.

Note: The installer uses the manifest files to know what is present or not,

which means that $INFORMIXDIR must be set to the directory to be modified,

and you must not change the manifest files outside of the installer. If

$INFORMIXDIR is not set correctly or if the manifest files are modified, the

installer might not perform as expected.
