AIX: Frequently Asking questions in HACMP

Reviewing cluster message log files The PowerHA SystemMirror hackp writes the messages it generates to the system console and to several log files. Following are log files which can be used for troubleshooting: Then read back through the log file to the first message relating to that problem.

Posted by Vineet at 7: The hostname cannot have following characters: Newer Post Troubleahooting Post Home. Using cluster log files. Each log file contains a different subset of messages generated by the PowerHA SystemMirror software. Many error messages cascade from an initial error that usually indicates the problem source.


The Volume mounted over NFS protocol is a file system for AIX, and since disk device is required for Enhanced concurrent capable volume group for disk heartbeat the NFS file system cannot be used for configuring the disk heartbeat. These messages provide valuable information tfoubleshooting understanding the current state of the cluster.

Also for all the resource groups on the Active node please specify the passive node as the next node in the priority to take over in the event of failure of active node. When viewed as a group, the log files provide a detailed troubleeshooting of all cluster activity.

This configuration will be useful if there is a failure of single Oracle Database instance on one node to be failed over to another node without troublexhooting other running Oracle instances. The event summaries included in this log make it easier to see quickly what events have occurred recently in the cluster.

Understanding the system error log The PowerHA SystemMirror software logs messages to the system error log whenever a daemon generates a state message. For this one needs to have separate Service IP addresses over which the listeners for every Oracle Database will run. The individual logs are limited to a troubleshooing size and are removed after they reach a certain age, or are overwritten by newer versions.


Resource group handling has been enhanced in recent releases and gacmp hacmp. Hence one can have separate Resource groups which will own each Oracle instance.

The following sections describe the types of messages output by the PowerHA SystemMirror software and the log files into which the system writes these messages.

Can multiple Service IP addresses be configured on single Ethernet cards? The verification process does not allow the IP addresses to be in same subnet and cluster will not start. The system cycles hacmp.

For instance, the hacmp. When checking this file, first find the most recent error message associated with your troubleehooting. Each copy is identified by a number appended to the file name.
