Error Message
VCS WARNING V-16-1-50034 No Resource dependencies are configured
Cause
CRS (cssd) is configured as single resource in its own service group (usually, cssd will be configured under cvm service group).
group sg_CSSD (
SystemList = { dbp01p = 0, dbp02p = 1 }
Frozen = 1
AutoFailOver = 0
Parallel = 1
AutoStartList = { dbp01p, dbp02p }
OnlineRetryLimit = 3
)
Application cssd (
Critical = 0
StartProgram = "/opt/VRTSvcs/rac/bin/cssd-online"
StopProgram = "/opt/VRTSvcs/rac/bin/cssd-offline"
CleanProgram = "/opt/VRTSvcs/rac/bin/cssd-clean"
MonitorProgram = "/opt/VRTSvcs/rac/bin/cssd-monitor"
OnlineRetryLimit = 20
)
requires group cvm online local firm
Resolution
-This WARNING message appears because of the way CRS (cssd) is configured. It’s in its own service group which has only 1 resource. Therefore there is no resource level dependency. However, our cssd application monitor script uses 'hares -dep' command assuming cssd will be configured under cvm service group and is dependent on cvm resources. The monitor script runs 'hares -dep' to check the status of the dependent resources.
VCS WARNING V-16-1-50034 No Resource dependencies are configured.
Duration (in seconds) between two consecutive monitor calls for an OFFLINE resource. If set to 0, OFFLINE resources are not monitored.
■ Type and dimension: integer-scalar
■ Default: 300 seconds
# grep hares clsinfo (clsinfo is run by the monitor script which check for dependency)
## 2. Groups on which CSSD's group directly depends is checked for
## online, but indirect dependencies are not checked
## 3. Only "online local firm" group dependencies are checked.
child_list=`$HAGRP -dep $group | $AWK '$1~/'$group'/ && $3~/online/ && $4~/local/ && $5~/firm/ { print $2}'`
child_list=`$HARES -dep $res | $AWK '$2~/'$res'/ { print $3}'`
-Our script is not designed to have cssd resoruce alone in its own Service Group.
-Nothing wrong here because there are no parent or child resources so the WARNING message can be ignored.
