Hi everyone, Need some help with ODP.NET and TAF please. It's 1am and I'm writing this email so you can see that I'm in dire straits! We've managed to successfully failover via SQL*Plus, but having problems getting ODP.NET to failover succesfully. Error encountered is ORA-1012 when it tries to fail over to the second instance. From all the doco's we've read, it appears that ODP.NET should work with TAF and failover transparently. Is there anything special that we need to check for? Being a DBA we're not sure of what to check for at the ODP.NET end. Is there a setting that we need to use? Are there known bugs and work-arounds with 9.2.0.4 TAF? We're using ODP.NET v9.2.0.4.01 Many thanks in advance, Leng. ---------------------------------------------- Leng Kaing Hansen Technologies 2 Frederick St; Doncaster VIC 3108 Tel: +61-3-9840-3832 Fax: +61-3-9840-3102
