Log scan input sources

Currently available log files

You must perform either a separate log scan to obtain the structure definitions for your old objects. This is the default input source for log scans, and is equivalent to specifying Subsystem BSDS on the Log File Selection panel or INPUT BSDS in batch syntax.

Individual Db2 log files

You must perform either a separate log scan to obtain the structure definitions for your old objects. To select this input source, specify Specific DB2 Log Files on the Log File Selection panel or INPUT DB2LOG in batch syntax.

Logical log files

You do not need to perform a separate step to obtain structure definitions. If a logical log file conforms to the published format, it includes structure definitions for all Db2 objects contained in the file.

To select this input source, specify Specific Logical Log Files on the Log File Selection panel or INPUT LLOG in batch syntax. If you specify more than one logical log file as input (directly or by specifying a GDG base), Log Master automatically runs in overtime mode.

Input image copies

Specify image copy data sets as an input source when the old objects reside in a compressed table space, or to enable row completion processing in overtime mode. Log Master uses the image copy to obtain a compression dictionary or complete log records.

To specify this input source, use the Specify Image Copies field on the Work ID Run Time Options panel or the IMAGECOPY statement in batch syntax. For more information about specifying input image copies, see the section about IMAGECOPY-statement.
