客户11.2.0.3 RAC环境，出现ORA-600[kollasg:client-side tmp lob]错误。
错误信息为：
Thu Apr 28 20:54:53 2011 Errors IN file /u01/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_ora_31916032.trc (incident=148665): ORA-00600: 内部错误代码, 参数: [kollasg:client-side tmp lob], [], [], [], [], [], [], [], [], [], [], [] Incident details IN: /u01/app/oracle/diag/rdbms/orcl/orcl1/incident/incdir_148665/orcl1_ora_31916032_i148665.trc Thu Apr 28 20:54:59 2011 Trace dumping IS performing id=[cdmp_20110428205459] Thu Apr 28 20:54:59 2011 Sweep [inc][148665]: completed Sweep [inc2][148665]: completed |
从错误信息上很容易判断，问题应该和客户端处理临时LOB有关。根据MOS文档ORA-00600 [kollasg:client-side tmp lob] Fetching Row With LOB Column in OCI Application [ID 1418135.1]，在11.1以上版本中，如果读取一个没有被初始化过的LOB列，会引发这个600错误。
Oracle给出的解决方案是对于空的CLOB，使用EMPTY_CLOB函数对齐进行初始化。
