The NODESIZE option specifies the size of the index nodes to use for an indexed file.
Syntax:
NODESIZE
=
size_of_node
Parameters:
-
size_of_node
- Use the following minimum NODESIZE values depending on the length of your keys:
| Key Length in Bytes |
Minimum NODESIZE Value in Bytes |
| Less than 51 |
512 |
| 51 through 100 |
1024 |
| 101 through 512 |
4096 |
| 513 through 4080 |
16384 |
Properties:
| Default: |
The minimum NODESIZE value for the key length, except that for key lengths less than 50 bytes, the default is 1024. |
Comments:
In most circumstances you should allow the File Handler to work out the appropriate default node size. However, if file size is an issue, smaller node sizes do result in a smaller index file, but you should be aware that they also increase processing time as the tree depth is greater.
