Search Again: ORA-12571: TNS:packet writer failure From: beagledos@netscape.net Date: Sunday, February 15, 2004 Time: 8:19:59 am Hi there, I recently apply service packs to my Windows 2000 Professional where I have installed Oracle Enterprise Server Version 8.1.5.0.0. Everything was fine until that. But now it is not possible to connect to Oracle (SQL*Plus, Toad or whatever). Error message is : "ORA-12571: TNS:packet writer failure". In sqlnet.log appears the next messages: VERSION INFORMATION: TNS for 32-bit Windows: Version 8.1.5.0.0 - Production Windows NT TCP/IP NT Protocol Adapter for 32-bit Windows: Version 8.1.5.0.0 - Production Time: 02-ENE-04 05:11:14 Tracing not turned on. Tns error struct: nr err code: 0 ns main err code: 12564 TNS-12564: TNS:connection refused ns secondary err code: 0 nt main err code: 0 nt secondary err code: 0 nt OS err code: 0 In listener.log appears the next one: TNS-12502: TNS:listener received no CONNECT_DATA from client TNS-12571: TNS:packet writer failure TNS-12560: TNS:protocol adapter error I suppose service pack 4 has replaced any dll regarding network. What can I do?, reinstall Net8?, reinstall Win2K?. Thanks in advance, JJ __________________________________________________________________ New! Unlimited Netscape Internet Service.
