ORA-600(17113)错误

又是一个PL/DEVELOPER的bug。
客户数据库是9.2.0.8,告警日志中出现大量下面的错误信息:

在详细TRACE文件/oracle9/app/admin/db/udump/db1_ora_1995124.trc中,可以看到这是一个DEVELOPER工具发起的会话:

   O/S info: USER: Administrator, term: PC2011100510, ospid: 2676:2564, machine: WORKGROUP\PC2011100510

    application name: PL/SQL Developer, hash VALUE=1190136663
    action name: Main SESSION, hash VALUE=1773317990

而导致错误的SQL语句为:

      AND object_type = 'MATERIALIZED VIEW'
      AND rownum = 1;
      :object_type := 'MATERIALIZED VIEW';

这显然是DEVELOPER在获取数据字典源数据时执行的SQL,关于这个错误的描述可以参考文档:ORA-00600: internal error code, arguments: [17113] using pl/sql developer [ID 396326.1]。
Oracle针对这个问题的解决方案只有一句,把pl/sql developer升级到最新版本。
