Description of the R-tree-specific logical-log records

As described previously, the R-tree secondary access method creates its own logical-log records for only two types of R-tree operations: insertion of an item into a leaf page and deletion of an item from a leaf page. For all other logged R-tree operations, the R-tree secondary access method allows the extensible log manager to create the logical-log record. These topics describe the format of the two logical-log records created by the R-tree secondary access method.

The first six columns of the R-tree-specific logical-log records are the standard columns displayed for all logical-log records. You can identify these log records as R-tree log records because the third column always has a value of RTREE. The R-tree-specific information is contained in the seventh column of the log record. An eighth column is also displayed, although its value is always 0.
