CleanRetryLimit (user-defined)	Number of times to retry the clean function before moving a resource to ADMIN_WAIT state. If set to 0, clean is re-tried indefinitely. The valid values of this attribute are in the range of 0-1024. Type and dimension: integer-scalar Default: 0
CleanTimeout (user-defined) Note This attribute can be overridden.	Maximum time (in seconds) within which the clean function must complete or else be terminated. Type and dimension: integer-scalar Default: 60 seconds
CloseTimeout (user-defined) Note This attribute can be overridden.	Maximum time (in seconds) within which the close function must complete or else be terminated. Type and dimension: integer-scalar Default: 60 seconds
ConfInterval (user-defined) Note This attribute can be overridden.	When a resource has remained online for the specified time (in seconds), previous faults and restart attempts are ignored by the agent. (See ToleranceLimit and RestartLimit attributes for details.) Type and dimension: integer-scalar Default: 600 seconds
EPClass	Enables you to control the scheduling class for the agent functions (entry points) other than the online entry point whether the entry point is in C or scripts. The following values are valid for this attribute: RT (Real Time) TS (Time Sharing) -1—indicates that VCS does not use this attribute to control the scheduling class of entry points. Use only one of the following sets of attributes to configure scheduling class and priority for VCS: AgentClass, AgentPriority, ScriptClass, and ScriptPriority Or OnlineClass, OnlinePriority, EPClass, and EPPriority Type and dimension: string-scalar Default: -1
EPPriority	Enables you to control the scheduling priority for the agent functions (entry points) other than the online entry point. The attribute controls the agent function priority whether the entry point is in C or scripts. The following values are valid for this attribute: 0—indicates the default priority value for the configured scheduling class as given by the EPClass attribute for the operating system. Greater than 0—indicates a value greater than the default priority for the operating system. Symantec recommends a value of greater than 0 for this attribute. A system that has a higher load requires a greater value. -1—indicates that VCS does not use this attribute to control the scheduling priority of entry points. For example: (Solaris) If the EPClass attribute is set to TS, and the value of the EPPriority attribute is set to 0, then the base priority for entry points is set to 59, as that is the default value set by the operating system. (Solaris) If the EPClass attribute is set to TS, and the value of the EPPriority attribute is set to -20, then the scheduling priority of the entry point would be 39 (59 base value and - 20 configured value) (Solaris) If the EPClass attribute is set to RT, and the value of the EPPriority attribute is set to 0, then the base priority for entry points is set to 100 by the operating system.

OfflineGroup:If the configured application is stopped outside of VCS control, VCS takes the corresponding service group offline. OfflineHold: If a configured application is stopped outside of VCS control, VCS sets the state of the corresponding VCS resource as offline. VCS does not take any parent resources or the service group offline. OfflineHold and OfflineGroup are mutually exclusive.
FaultOnMonitor Timeouts (user-defined) Note This attribute can be overridden.	When a monitor times out as many times as the value specified, the corresponding resource is brought down by calling the clean function. The resource is then marked faulted, or it is restarted, depending on the value set in the RestartLimit attribute. When FaultOnMonitorTimeouts is set to 0, monitor failures are not considered indicative of a resource fault. A low value may lead to spurious resource faults, especially on heavily loaded systems. Type and dimension: integer-scalar Default: 4
FaultPropagation (user-defined) Note This attribute can be overridden.	Specifies if VCS should propagate the fault up to parent resources and take the entire service group offline when a resource faults. The value 1 indicates that when a resource faults, VCS fails over the service group, if the group's AutoFailOver attribute is set to 1. If The value 0 indicates that when a resource faults, VCS does not take other resources offline, regardless of the value of the Critical attribute. The service group does not fail over on resource fault. Type and dimension: boolean-scalar Default: 1
FireDrill (user-defined)	Specifies whether or not fire drill is enabled for resource type. If set to 1, fire drill is enabled. If set to 0, it is disabled. Type and dimension: boolean-scalar Default: 0
InfoInterval (user-defined)	Duration (in seconds) after which the info function is invoked by the agent framework for online resources of the particular resource type. If set to 0, the agent framework does not periodically invoke the info function. To manually invoke the info function, use the command `hares` `-refreshinfo`. If the value you designate is 30, for example, the function is invoked every 30 seconds for all online resources of the particular resource type. Type and dimension: integer-scalar Default: 0
IntentionalOffline (user-defined)	Defines how VCS reacts when a configured application is intentionally stopped outside of VCS control. Add this attribute for agents that support detection of an intentional offline outside of VCS control. Note that the intentional offline feature is available for agents registered as V51 or later. The value 0 instructs the agent to register a fault and initiate the failover of a service group when the supported resource is taken offline outside of VCS control. The value 1 instructs VCS to take the resource offline when the corresponding application is stopped outside of VCS control. Type and dimension: boolean-scalar Default: 0
InfoTimeout (user-defined)	Timeout value for info function. If function does not complete by the designated time, the agent framework cancels the function's thread. Type and dimension: integer-scalar Default: 30 seconds
LogDbg (user-defined)	Indicates the debug severities enabled for the resource type or agent framework. Debug severities used by the agent functions are in the range of dbg_1-dbg_21.

MonitorInterval (user-defined) Note This attribute can be overridden.	Duration (in seconds) between two consecutive monitor calls for an online or transitioning resource. A low value may impact performance if many resources of the same type exist. A high value may delay detection of a faulted resource. Note The value of this attribute for the MultiNICB type must be less than its value for the IPMultiNICB type. See the Veritas Cluster Server Bundled Agents Reference Guide for more information. Type and dimension: integer-scalar Default: 60 seconds
MonitorStatsParam (user-defined)	Stores the required parameter values for calculating monitor time statistics. static str MonitorStatsParam = {Frequency = 10, ExpectedValue = 3000, ValueThreshold = 100, AvgThreshold = 40} Frequency: The number of monitor cycles after which the average monitor cycle time should be computed and sent to the engine. If configured, the value for this attribute must be between 1 and 30. The value 0 indicates that the monitor cycle ti me should not be computed. Default=0. ExpectedValue: The expected monitor time in milliseconds for all resources of this type. Default=100. ValueThreshold: The acceptable percentage difference between the expected monitor cycle time (ExpectedValue) and the actual monitor cycle time. Default=100.

Thus, setting NumThreads to 1 forces the agent to just use 1 service thread no matter what the resource count is. The agent framework limits the value of this attribute to 30. Type and dimension: integer-scalar Default: 10
OfflineMonitorInterval (user-defined) Note This attribute can be overridden.	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

The following values are valid for this attribute: RT (Real Time) TS (Time Sharing) -1—indicates that VCS does not use this attribute to control the scheduling class of entry points. Use only one of the following sets of attributes to configure scheduling class and priority for VCS: AgentClass, AgentPriority, ScriptClass, and ScriptPriority Or OnlineClass, OnlinePriority, EPClass, and EPPriority Type and dimension: string-scalar Default: -1
OnlinePriority	Enables you to control the scheduling priority for the online agent function (entry point). This attribute controls the priority whether the entry point is in C or scripts. The following values are valid for this attribute: 0—indicates the default priority value for the configured scheduling class as given by the OnlineClass for the operating system. Symantec recommends that you set the value of the OnlinePriority attribute to 0. Greater than 0—indicates a value greater than the default priority for the operating system. -1—indicates that VCS does not use this attribute to control the scheduling priority of entry points. For example: (Solaris) If the OnlineClass attribute is set to TS, and the value of the OnlinePriority attribute is set to 0, then the base priority for entry points is set to 59, as that is the default value set by the operating system. (Solaris) If the OnlineClass attribute is set to TS, and the value of the OnlinePriority attribute is set to -20, then the scheduling priority of the entry point would be 39 (59 base value and - 20 configured value) (Solaris) If the OnlineClass attribute is set to RT, and the value of the OnlinePriority attribute is set to 0, then the base priority for entry points is set to 100 by the operating system. Use only one of the following sets of attributes to configure scheduling class and priority for VCS: AgentClass, AgentPriority, ScriptClass, and ScriptPriority Or OnlineClass, OnlinePriority, EPClass, and EPPriority Type and dimension: string-scalar Default: -1
