RHBA-2014:1424 - Bug Fix Advisory

Topic

Updated sapconf package that fixes several bugs is now available for Red Hat
Enterprise Linux 6.

Description

The sapconf package contains a script that checks the basic installation of Red
Hat Enterprise Linux and modifies it according to SAP requirements. The script
ensures that all necessary packages are installed and that configuration
parameters are set correctly to run SAP software.

This update fixes the following bugs:

• In certain situations, the sapconf script created the /etc/hosts file in an

incorrect format, thus the file did not return the fully qualified domain name
(FQDN). As a consequence, SAP installation failed unexpectedly. With this
update, the script has been edited to handle situations when the incorrect
/etc/hosts file was created. In addition, when FQDN is not returned properly,
the script exits with the error code 4. (BZ#1024356)

• Previously, the manual page for the sapconf script was missing. This update

adds the missing manual page to the sapconf package. (BZ#1025187)

• Due to a bug in the underlying source code, the sapconf script was unable to

verify if a virtual guest was a VMware guest. Consequently, an attempt to use
sapconf on such a guest failed. With this update, sapconf recognizes the VMware
guests as expected. (BZ#1040617)

• The order of reading limit files in Red Hat Enterprise Linux is as follows:

First is read the /etc/security/limits.conf file and then the limit files
located in the /etc/security/limits.d/ directory according to the C localization
functions. When an entry is specified in two or more files, the entry that is
read last takes effect. Previously, the sapconf script wrote entries to
/etc/security/limits.conf, which could cause the sapconf entries to be
overwritten by the same entries in files located in /etc/security/limits.d/.
With this update, a separate sapconf limit file has been added to
/etc/security/limits.d/ to anticipate this bug. (BZ#1051017)

• When the sapconf script updated the /etc/hosts file, permissions of that file

were incorrectly modified. This update applies a patch to fix this bug, and
sapconf no longer overwrites the file's permissions. (BZ#1083651)

Users of sapconf are advised to upgrade to this updated package, which fixes
these bugs.
