Appendix A Files for Configuring and Removing Sun Cluster HA for Sun Grid Engine Resources

The /opt/SUNWscsge/util directory contains files that automate the process of configuring and removing Sun Cluster HA for Sun Grid Engine resources. Listings of these files are provided in the following sections:

• Listing of sge_config

• Listing of sge_register

• Listing of sge_remove

# This file will be sourced in by sge_register and the parameters
# listed below will be used.
#
# These parameters can be customized in (key=value) form and are always needed:
#
#	QMASTERRS  - name of the resource for the sge_qmaster daemon.
#	SCHEDDRS   - name of the resource for the sge_schedd daemon.
#	MASTERRG   - name of the resource group containing the resources
#	             for sge_qmaster and sge_schedd.
#	MASTERPORT - tcp port number that sge_qmaster will listen to
#		     (normally 536).
#	MASTERLH   - name of the LogicalHostname SC resource within MASTERRG.
#	MASTERHASP - name of the HAStoragePlus SC resource within MASTERRG.
#	SGE_ROOT   - SGE_ROOT of this Sun GridEngine Installation.
#	SGE_CELL   - SGE_CELL of this Sun GridEngine Installation.
#	SGE_VER    - Version of this Sun GridEngine Installation.
#	             Currently this can only be set to 6.0 .
