Frequently Asked Questions for Informix

How do we Protect Informix Data on a non-global Zone?

In order to enable consistent backups of Informix data on a non-global zone, you need to install the Informix iDataAgent on the non-global zone.

Can we protect data on non-global zones if the File System Data Agent is installed only on the global zone?

Yes. We can protect file system data on non-global zones if the File System iDataAgent is installed only on the global zone. However, in order to enable consistent backups of application specific data on the non-global zones, you will need to install the corresponding application specific iDataAgent on the non-global zone.

What are the folders and files created during the installation of this agent?

How can I view the progress of a backup or restore?

You can view the status of a backup or restore operation from the ON-Bar activity log. The ON–Bar utility writes informational, progress, warning, error, and debugging messages to the ON–Bar activity log. The activity log also records which dbspaces and logical logs were backed up or restored, the progress of the operation, and the approximate duration of each operation. You can use the information in the activity log to determine whether a backup or restore operation succeeded or failed. The ON-Bar Activity Log location can be found in the ONCONFIG file and the parameter name is BAR_ACT_LOG.

Can we perform backup and restore jobs with multiple sqlhostfiles?

Yes. You need to set InformixServername_SQLHOSTFile followed by the path to the SQLHOSTFILE for each Informix server. This will help you to successfully perform backup and restore jobs with multiple SQLhostfiles.

Can we fail a backup job that goes in to a pending state?

Yes. You can fail a backup job that goes in to a pending state by configuring DoNotRetryBackup.

Can we debug Informix backup and restore jobs?
