Janinie,
Yes I am verifying if you need the compat libs for Oracle 8.1.7 on Redhad 8.0. I don't know if this applies to 7.3 or not.
I have passed the acceptance.sql test, but I will install OpenACS today, fingers crossed. I'll post my results on the thread dealing with this issue. For now all I have done is to set LD_ASSUME_KERNEL=2.2.5 in every environment using oracle, and I installed the glibc stub patch, which is available with the 8.1.7 download.
