100About Veritas Storage Foundation and High Availability SolutionsKnown issuesSee the Veritas Cluster Server Agent for Oracle Installation and ConfigurationGuide for a description of the actions.Currently, the reference file specifies the NOFAILOVER action when the followingOracle errors are encountered:ORA-00061, ORA-02726, ORA-6108, ORA-06114The NOFAILOVER action means that the agent sets the resource’s state to OFFLINEand freezes the service group. You may stop the agent, edit the oraerror.dat file,and change the NOFAILOVER action to another action that is appropriate for yourenvironment. The changes go into effect when you restart the agent.ASMInstance resource monitoring offline resource configured with OHASDas application resource logs error messages in VCS logs [2846945]When the Oracle High Availability Services Daemon (OHASD) is configured as anapplication resource to be monitored under VCS and if this resource is offline onthe failover node then the ASMInstance resource in the offline monitor logs thefollowing error messages in the VCS logs:ASMInst:asminst:monitor:Cluster Synchronization Serviceprocess is not running.Workaround: Configure the application in a separate parallel service group andensure that the resource is online.Issues related to the agent frameworkIssues with configuration of resource values (1718043)If you configure a resource that has more than 425 values in its ArgListValues,the agent managing that resource logs a message such as:VCS WARNING V-16-2-13806 Thread(1437547408) ArgListValues overflow;Cannot append values more than upper limit of (425).Normally, the number of values in ArgListValues for a resource must not exceed425. However, in case of a keylist, association or vector type of attribute appearsin the ArgList for a resource-type. Since these attributes can take multiple values,there is a chance for the resource values in ArgListValues to exceed 425.Agent may fail to heartbeat under heavy load [2073018]An agent may fail to heart beat with the VCS engine under heavy load.This may happen when agent does not get enough CPU to perform its tasks andwhen the agent heartbeat exceeds the time set in the AgentReplyTimeout attribute.
About Veritas Storage Foundation and High Availability SolutionsKnown issues101The VCS engine therefore stops the agent and restarts it. The VCS engine generatesa log when it stops and restarts the agent.Workaround: If you are aware that the system load is likely to be high, then:■■The value of AgentReplyTimeout attribute can be set to a high valueThe scheduling class and scheduling priority of agent can be increased to avoidCPU starvation for the agent, using the AgentClass and AgentPriority attributes.Agent framework cannot handle leading and trailing spaces for thedependent attribute (2027896)Agent framework does not allow spaces in the target resource attribute name ofthe dependent resource.Workaround: Do not provide leading and trailing spaces in the target resourceattribute name of the dependent resource.The agent framework does not detect if service threads hang inside anentry point [1442255]In rare cases, the agent framework does not detect if all service threads hanginside a C entry point. In this case it may not cancel them successfully.Workaround: If the service threads of the agent are hung, send a kill signal torestart the agent. Use the following command: kill -9 hung agent's pid. Thehaagent -stop command does not work in this situation.IMF related error messages while bringing a resource online and offline[2553917]For a resource registered with AMF, if you run hagrp -offline or hagrp -onlineexplicitly or through a collective process to offline or online the resourcerespectively, the IMF displays error messages in either case.The errors displayed is an expected behavior and it does not affect the IMFfunctionality in any manner.Workaround: No workaround.Issues related to VCS in Japanese localesThis section covers the issues that apply to SF in a Japanese locale.The hares -action command displays output in English [1786742]The hares -action command incorrectly displays output in English.
