Solaris 2.9 Oracle 9i 64 bit Have successfully executed tg4ifmx Have successfully tested odbc Can use tnsping for either heterog. services or the gateway for informix (have configured both). However, get these messages when using the database link using either one: SQL> select * from dual@tg4ifmx; select * from dual@tg4ifmx * ERROR at line 1: ORA-02068: following severe error from TG4IFMX ORA-28511: lost RPC connection to heterogeneous remote agent using SID=%s ORA-28509: unable to establish a connection to non-Oracle system Relentlessly searched for errors on Metalink like above - without much help. Also, gateway trace provides a bit more information which I also searched Metalink for: [G000] Failed to notify driver of changed property ISOLATION_LEVEL for TDP GTWCSD2D Tar is been sitting there for awhile. Has anyone dealt with the errors above??? ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
