DBD::Oracle says:

There are also legacy LONG types (LONG, LONG RAW, VARCHAR2) which are presently deprecated by Oracle but are still in use. These LONG types do not utilize a 'LOB Locator' and also are more limited in functionality than CLOB or BLOB fields.

I misread your question and assumed you meant lobs and not the old deprecated long type. I don't use longs so I cannot say but the comment above would suggest there is not a lob locator.

I guess you need to read this.
