The following table shows the formulas for determining the file sizes required for the execution of the dictionary import/export utility (pdexp):
| File type |
Formula (bytes) |
| Export file |
Base table |
0.8 + 0.4 (a + b) + (0.8 + 0.1 c) d + 0.1 f |
| View table |
0.5 + 0.4 a + e |
| Procedure |
1.0 + 0.1 g + h |
- a: Number of columns in table to be exported
- b: Number of partitioning conditions for table to be exported
- c: Number of index storage RDAREAs defined for table to be exported
- d: Number of indexes defined for table to be exported
- e: Length of the source during view table definition (KB)
- f: If a LOB column is defined in the table to be exported, this is the number of user LOB RDAREAs storing the LOB data.
- g: Number of resources used by a stored procedure that is exported*
- This is the value of the N_RESOURCE column in the SQL_ROUTINES table.
- h: Length of the source of a stored procedure (KB)
- This is the value of the SOURCE_SIZE column in the SQL_ROUTINES table.
- * If exporting multiple tables, determine the previously described sizes for each table. The sum of the sizes obtained is the size of the export file.
