Step-by-Step Cluster Conversion
Serviceguard Extension for SAP on Linux Configuration – sap.config
Chapter 3 151
Configuration of Application Server Handling
In more complicated setups, in directory ${SGCONF}/<SID> there can be
several XXX.config files for each package. For example a Dialog
Instance package can have its own sap<pkg_name>.config configured to
start additional non-critical Dialog Instances, whereas this setting
should not be effective for a Central Instance package with the same SID.
During startup of a package <pkg_name>, Serviceguard Extension for
SAP on Linux checks the existence of SAP specific configuration files in
the following order:
•If a sap.conf file exist, it is effective for compatibility reasons.
•If a sap<pkg_name>.conf file exist, it will overrule previous files
and is effective.
•If a sap.config file exist, it will overrule previous files and is
effective.
•If a sap<pkg_name>.config file exist, it will overrule previous files
and is effective.
NOTE When configuring package specific configuration files
sap<pkg_name>.config you will usually isolate section 1 in a global
sap.config file. All other sections should then be applied in the package
specific configuration files sap<pkg_name>.config, excluding the first
section.
For example SAP System C11 containing a Central Instance package
with Application Server handling would then have the following
Serviceguard Extension for SAP on Linux configuration files:
• sap.config – Section 1,3,4 configured
• sapciC11.config – Section 2 configured
OS670 Optional Step:
The following arrays are used to configure special treatment of
Application Servers during package start, halt or failover. These
Application Servers are not virtualized or part of a Serviceguard
package, but an attempt can be triggered to start, stop or restart them
with the package. If any triggered attempt fails, it doesn't automatically
cause failure of the ongoing package operation. The attempts are
