Hi, For sometime I have been receiving the log above from sqlnet.log of my dataguard(jupiter) server: * Fatal NI connect error 12514, connecting to:* * (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=spirit01vip)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=BDSTPRD_DGB)(SERVER=dedicated)(CID=(PROGRAM=oracle)(HOST=jupit * *er)(USER=oracle))))* * * * VERSION INFORMATION:* * TNS for Linux: Version 10.2.0.4.0 - Production* * TCP/IP NT Protocol Adapter for Linux: Version 10.2.0.4.0 - Production* * Time: 14-APR-2010 11:26:04* * Tracing not turned on.* * Tns error struct:* * 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* * * * * * * We do not have Dataguard Broker (DGB) and we dont want it. Any ideas in pinpointing why the system is generating the logs? Thanks. Özgür Özdemircili http://www.acikkod.org Code so clean you could eat off it
