The 'stop' operation stops WAS6. The 'status' operation reports whether WAS6 is running The 'monitor' operation reports whether the WAS6 seems to be working (httpd also needs to be working for this case) The 'validate-all' operation reports whether the OCF instance parameter (OCF_RESKEY_profileName ) is valid The 'methods' operation reports on the methods $0 supports This is known to work with the Single Server edition of Websphere. The default profile name for the single server edition is: $DEFAULT The start and stop operations must be run as root. The status operation will report a pid of "-" for the WAS root process using unless it is run as root. If you don't have xmllint on your system, parsing of WAS configuration files is very primitive. We run servlet/snoop on the seventh transport port listed in the config file for the "monitor" operation. END } meta_data() { cat < 1.0 Resource script for WAS6.
