Troubleshooting Db2 High Availability Instance Configuration Utility (db2haicu)

Use the information in this topic to troubleshoot the db2haicu utility.

The high availability instance configuration utility (db2haicu) sends logs to the db2diag.log file. This is the primary means for debugging issues related to the db2haicu utility. Furthermore, the db2haicu process performs extensive inter-process communication with the db2havend process for interactions with the cluster manager API. Examining messages in the db2diag.log files for both db2haicu and db2havend can help understand the cause of a db2haicu command failure.

The other two main sources of information when troubleshooting issues related to the db2haicu utility are the system logs (the /var/log/messages file for Red Hat based Linux operating systems), and the TSAMP diagnostic data. The TSAMP diagnostic data can be collected by running the following command as root on all hosts within your TSAMP cluster:

getsadata -all

If the root cause of the problem cannot be identified from inspection of these diagnostic data sources, contact IBM Support.
