Archive Basics

The page displays the following archive settings for the active namespace:

Archive to namespace — The namespace to which InterSystems IRIS® saves archived messages.
Archive manager class name — The class that acts as the Archive Manager. Use Ens.Archive.ManagerOpens in a new tab or a custom class, if available.
See Defining a Custom Archive Manager.
Number of days before archiving — Messages older than this number of days are automatically archived when you run the archive operation.
If the Archive Manager performs purging, note that the activity of purging generates extra journaling, especially when you purge large volumes of data; see First-time Purges,“” earlier in this book.

The Archive Manager requires you to identify a namespace in which to keep the archive. InterSystems strongly recommends that you keep this archive in a namespace that meets both of the following criteria:

A separate namespace from those in which you run productions. If you are running productions in more than one namespace, be aware that multiple namespaces can archive their messages into one shared target namespace.
An interoperability-enabled namespace, so that you can use the Management Portal features such as the Message Viewer and Visual Trace whenever you have a reason to examine the archived messages. For details about interoperability-enabled namespaces, see Environmental Considerations.

Click Edit to the right of the namespace to update these settings. Change the information in the fields and then click Save. If the save is successful, the page is refreshed with the new settings displayed. If the save failed, the form displays the error message from the server.

The Archive history display provides information about the last or current archive. For example:

Archive start time  2012-01-05 12:06:10
Archive stop time  2012-01-05 12:06:10
Total messages processed  70 - 100% finished
