VCS Oracle Listener Agent: Can it be Configured to Failover After 'n' Times of Successive Failures?

Hi all, We are trying to work around an issue where VCS Oracle listener agent received some garbled characters after issueing 'status' command causing the listener and its db to failover. This happened even though the listener never went down as other monitors did not trigger and the log file did not show any downtime. We consulted Oracel and Symatec support, but received not definitive answers. The issue is very sporadic and is very hard to reproduce. One way we thought we could tackle it is to configure the VCS agent to failover the resource after n or may be 3 times of successive failures vs. the default of 1. - Has anyone run into this issue before? - Can the agent be configured as such? Thank you.

Yes , the agent could be configured to fail over after n number of successive faults. You need to configure
the ToleranceLimit attribute for the Listener Type. This is a type level attribute and not resource level.

ToleranceLimit
A non-zero ToleranceLimit allows the monitor entry point to return OFFLINE
several times before the ONLINE resource is declared FAULTED. If the monitor
entry point reports OFFLINE more times than the number set in ToleranceLimit,
the resource is declared FAULTED. However, if the resource remains online for
the interval designated in ConfInterval, any earlier reports of OFFLINE are not
counted against ToleranceLimit. Default is 0. The ToleranceLimit attribute
value can be overridden.
