Hi there I am trying to get DBD::Unify working on AIX 5.3 (Unify DS 7.2), it compiles OK, however, when I try to connect, I get an error -59 unable to attach to shared memory message. I have tried version 0.42, 0.50 and 0.60, they all exhibit the same behavior. I am using perl 5.8.8 and DBI version 1.51 Thanks in advance for any suggestions. Regards Alan
