-------------------------------------------------------------------------------- Modified 22-APR-2010 Type HOWTO Status ARCHIVED In this Document Goal Solution -------------------------------------------------------------------------------- Applies to: Oracle Agile Application Administration Information in this document applies to any platform. ***Checked for relevance on 22-April-2010*** Oracle 8.1.7 Goal Oracle Trace Error:The 'FATAL ERROR IN TWO-TASK SERVER: error =12571' Solution Restart the eHub services The ora-12571 error usually occurs when the client abruptly terminates with a Ctrl-C or powers down. OR The ora-12571 error, usually, indicates an instability with Oracle with the network. Communication Gap between eHub and Database Server. 从上面的情形可知，两种情况导致了ora-12571。一是意外终止或按下Ctrl-C，二是网络不稳定所致，而导致前面描述的ORA-02409 更多有关ORA-02409的文章 ID 164839.1 ID 19332.1 ID 789517.1
