Hello Barry,
I can't comment on the Solaris 9/Oracle 10g combination. I am trying now Oracle 10g on a redistribution of RHEL 3.0 and I not having the issue you describe. Using OpenACS 5.1 as well, AOLServer 4.01 and nsoracle 2.7 (I did a checkout from HEAD of nsoracle but I thought it might be already too much to be running 10g so I decided to be a bit more conservative).
I am having other strange issues, for example, when I start AOLServer, sometimes, I get these errors:
[30/May/2004:19:51:15][843.3073884288][-main-] Error: nsoracle.c:3526:Ns_OracleGetRow: error in `OCIStmtFetch ()': ORA-01406: fetched column value was truncated
SQL: [nil]
I can't seem to be able to reproduce this consistently and when I restart, in most cases, it works fine.
Is anyone using Oracle 10g with OACS 5.1?
