=====================
Reverting to the previously installed C++ Runtime Level
To revert to the V6.0 C++ runtime level, use the following steps:

1. Download the base runtime and the fix level (if applicable) of the C++ runtime you recorded before installing the Runtime Environment component. The base runtime and fix levels can be found at:

http://www.ibm.com/software/awdtools/vacpp/support/

A compressed archive containing the base level C++ runtime libraries filesets can be obtained from:

ftp://ftp.software.ibm.com/aix/products/ccpp/xlc.600.runtime.aix.tar.Z


2. Force install the base level of the C++ runtime with the -F option, using the following command:

-> installp -aFXd <location> xlC.rte xlC.aix50.rte xlC.msg.LANG.rte

where: <location> is the location of the install images


3. Apply the fix level (if required), using the following command:

-> installp -aXd <location> <fileset_to_update>

where:

<location> is the location of the install images.
<fileset> is the fileset to update.

or commit the fix level, using:

-> installp -acXd <location> <fileset>

where:

<location> is the location of the install images.
<fileset> is the fileset to update.
