SPAN ENTRIES filename
where filename is the name of the Span parameter patch file.
This parameter writes all audit location information that is compatible with Span to a single file, rather than creating separate patch files for each cloned data set. You can insert this patch file (by default, DATA/SNAPSHOT/databasename/SPANCONTROL) into the Span parameter file and use Span to continue replicating those data sets.
If SPAN ENTRIES is not specified, Snapshot writes the audit location information to individual patch files, one for each data set. You can insert one or more of these patch files into the Span parameter file for continued replication. This technique may be more suitable for situations where you run Snapshot for different groups of data sets because the audit location information from one group will not erase the information for another group.
