The limit of five logical file extents for each Adabas file extent type has been lifted. The maximum number of logical file extents that can be defined is limited only in that the extent information of all address converters, Data Storage, normal index, and upper index extents for the file must fit into the file control block (FCB). (The extent information is stored in a variable section of the FCB.) For example, on a standard 3390 device type, a file could have more than 40 extents of each type (or there could be more of one type if there are less for another). For more information about Adabas 8 logical extents, see Adabas Logical Extents in the Adabas 8 for Mainframes documentation.
For Adabas version 8 databases, the extent list saturation of the files can optionally be displayed in the List Files detail-view. For detailed information see Changing the Columns in the File List Display in Listing Database Files.
To view files with extent list saturation:
Select an Adabas version 8 database in tree-view and expand it.
Select Database Files in tree-view and right-click it.
Select on the drop-down menu.
The Files with Extent List Saturation panel appears in detail-view.
Note:
You can cancel the operation at any time by selecting
on the
drop-down menu.
If no files with critical saturation exist in the database, a message will be displayed in the Files with Extent List Saturation panel.
