libc6 version in testing dist

["Peter Leipold" <peter.leipold@eQonline.fi>]

Hi!

I have a testing distrib. I did an "apt-get upgrade", and now I have "libc6 
2.3.1-16". However the package list on www.debian.org says testing should 
contain "libc6 2.2.5-9.woody.3".

My sources.list file:
deb ftp://ftp.fi.debian.org/debian testing main non-free contrib

The main problem is that I have a program which misses glibc 2.2. It says:
sqlplus: /lib/ld-linux.so.2: version `GLIBC_2.2' not found (required by 
/usr/local/oracle/product/8.1.7/lib/libclntsh.so.8.0)

I can't upgrade this prog, so I have to do something with the debian. Can I 
downgrade somehow? Or any ideas how to solve this?

Sorry if this is a novice question...

Peter
