Output description - Ongoing archives

This output section represents current information about the archives. If no archives are active in the system, this section is not displayed.
Column Description
Number The number of the dbspace
Name The name of the dbspace
Q Size The before-image queue list size. This information is primarily for IBM® support.
Q Len The before-image queue length. This information is primarily for IBM support.
Buffer The number of pages used in the before-image buffer
Partnum The partition number of the before-image bin
Size The number of pages in the before-image bin
Current-page The current page that is being archived
Note: The before-image bin is a temporary table created in a temporary dbspace, or in the root dbspace if you do not have any temporary dbspaces. If the before-image bin becomes too small, it can extend to additional partitions, in which case the output will display see multiple Partnum and Size fields for the same dbspace.

Output description - Archive status

This output section contains information about the last backup that has occurred for each dbspace.
Column Description
Name The name of the dbspace
Number The dbspace number
Level The archive level
Date The date and time of the last archive
