Integer overflow in OCI8

< ^ > P N |<>|^_>< --- | ~ ...Help
Hi,

I`m writing a tiny agent in ruby to simplyfy my daily dba jobs and 
monitor the database activity, especially the state of my standby databases.

My library of choice is RubyOCI8 because it`s the only one I think, 
where I can logon as SYSDBA. Please correct me if I wrong!

The following statement caused OCI8 to die
SQL> SELECT * FROM DBA_TEMP_FILES;

OCIError: ORA-01455: Ueberlauf von Integer-Datentyp bei Umwandlung der
Spalte
#translation: Overflow of integer-datatype during conversion of column

         from c:/ruby/lib/ruby/site_ruby/1.8/OCI8.rb:499:in `fetch'
         from c:/ruby/lib/ruby/site_ruby/1.8/OCI8.rb:499:in `fetch_a_row'
         from c:/ruby/lib/ruby/site_ruby/1.8/OCI8.rb:499:in `do_ocicall'
         from c:/ruby/lib/ruby/site_ruby/1.8/OCI8.rb:499:in `fetch_a_row'
         from c:/ruby/lib/ruby/site_ruby/1.8/OCI8.rb:312:in `fetch'
         from ./lib/database.rb:284:in `tempfiles'
         from (irb):16


My system:
RDBMS Oracle 9.2.0.4 Enterprise / Standard Edition (tested both)
Client 9.2.0.6 / 10.0.1.3 (tested both)
OS: Windows 2000 / 2003 (Client / Server)
RubyInstaller is up to date

The killing value seems to be the column MAXBYTES with a value of 
34,359,721,984. The strange thing is, if I call DBA_DATA_FILES instead, 
where MAXBYTES is equal to MAXBAYTES in *_TEMP_FILES, I got no problems.

Can anyone imagine what`s the problem ?

Below you see the result of the query in SQL*Plus.

Thx
Andreas
