Localized
Oracle
mount
points
Localized Oracle environments are different depending on whether you connect
asinternalor assysdba. A database on a localized mount point must be created
with “connect / as sysdba” if it is to be put under LifeKeeper protection.
Apache
updates
Upgrading an SPS protected Apache application as part of upgrading the Linux
operating system requires that the default server instance be disabled on start up.
If your configuration file (httpd.conf) is in the default directory (/etc/httpd/conf), the
Red Hat upgrade will overwrite the config file. Therefore, you should make a copy
of the file before upgrading and restore the file after upgrading.
Also, see the Specific Configuration Considerations for Apache Web Server
section in theApache Web Server Recovery Kit Administration Guide.
Storage and Adapter Configuration
Item Description
Multipath I/O and
Redundant Controllers
There are several multipath I/O solutions either
already available or currently being developed for
the Linux environment. SIOS Technology Corp.
is actively working with a number of server
vendors, storage vendors, adapter vendors and
driver maintainers to enable LifeKeeper to work
with their multipath I/O solutions. LifeKeeper’s
use of SCSI reservations to protect data
integrity presents some special requirements
that frequently are not met by the initial
implementation of these solutions.
Refer to the technical notes below for supported
disk arrays to determine if a given array is
supported with multiple paths and with a
particular multipath solution. Unless an array is
specifically listed as being supported by
LifeKeeper with multiple paths and with a
particular multipath solution, it must be assumed
that it is not.
