Managing Serviceguard Extension for SAP Version A.06.00 for Linux, December 2012

The following table describes the SGeSAP parameters and their respective values:
DescriptionPossible valueParameter
Defines the unique SAP System Identifier
(SAP SID)
C11sgesap/sap_global/sap_system
Defines the commands for remote
executions.
ssh
rsh
sgesap/sap_global/rem_comm
Default is ssh
Allows the parallel startup of SAP
application server instances.
yes
no
sgesap/sap_global/parallel_startup
If set to no, the instances start
sequentially.
Before the instance startups, the
package attempts to free up unsused
normal
lazy
sgesap/sap_global/cleanup_policy
system resources (temporary files, IPC
strict
resources, and so on.) in order to make
the startups more likely to succeed.
A database package only frees up
database related resources. SAP
instance packages only remove IPCs
belonging to SAP administrators.
If this parameter is set to normal, only
instance shared memory is cleaned up.
If this parameter is set to lazy, cleanup
is deactivated.
If this parameter is set to strict and
process is not attached, all shared
memory - regardless of whether it is s
cleaned up.
NOTE: Using the strict setting can
crash running instances of different SAP
Systems on the failover host.
Specifies the number of retries for
several cluster operations that might not
5sgesap/sap_global/retry_count
succeed immediately due to racing
conditions with other parts of the
system.
The Default is 5.
Specifies whether the SAP sapcontrol
interface and the SAP startup agent
preferred
exclusive
sgesap/sap_global/sapcontrol_usage
framework are required for startup,
disabled
shutdown, and monitoring of SAP
software components.
Setting the value to preferred ensures
that all the available SAP-provided
legacy monitoring tools are used in
addition to the agent framework
monitors.
When the value is exclusive only the
sapcontrol is used to start, stop, and
monitor SAP instances
When the value is disabled the
sapcontrol method is not used to
start, stop, and monitor SAP instances.
The default is preferred.
