I seem to be having problems understanding exactly what I should do to get Listserv 15.5 hooked up to a MySQL database on a fairly old (Fedora 6) server. Here's the bit from go.user: The hook in go.user: UODBC_DSN="listserv" UODBC_UID="[redacted]" UODBC_AUTH="[redacted]" export UODBC_DSN UODBC_UID UODBC_AUTH Here's the error I'm getting: Serious error occurred - traceback follows ------------------------------------------ >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize >>> Error X'01000033' opening DBMS list <<< -> Severity: Error -> Facility: DBMS interface -> Abstract: DBMS driver failed to initialize Here's the relevant line from the list header: DBMS= UODBC,Table(LISTSERV),Email(email),Name(name),Uemail(uemail) Using isql shows: [mickc@gandalf etc]# isql -v listserv [redacted] [redacted] SQL> show tables; +-----------------------------------------------------------------+ | Tables_in_listserv | +-----------------------------------------------------------------+ | changelog | +-----------------------------------------------------------------+ SQLRowCount returns 1 1 rows fetched Can someone suggest where I've gone wrong here?
