测试环境的新建表空间在删除时报错。
数据库创建一个新的表空间后执行删除，出现了ORA-600的错误信息：

005BEB860 ? 6AF000900000001 ?--------------------- Binary Stack Dump ---------------------可以看到，报错发生在删除一个表上。而这个表在数据库中应该是不存在的，或者说即使这个表存在，也不可能建立在这个表空间。那么导致问题的原因应该只有一个，数据字典出现了不一致的状态。

TS#COUNT(*)---------- ----------1116202112645755014296ROWSselected.SQL>SELECTts#,COUNT(*)FROMtab$GROUPBYts#;
TS#COUNT(*)---------- ----------6429119722475544883072073691012210ROWSselected.可以看到，在SEG$中不存在表空间编号大于6的对象，但是在TAB$中确存在很多。

TS# NAME---------- ------------------------------0SYSTEM1UNDOTBS2SYSAUX3TEMP4TBS_15GGX6USERS7PERFSTAT8STATSPACK9ALA_TEST10ROWSselected.可以看到，表空间目前编号只到9，而TAB$中记录的表空间的编号以及到了12。显然这就是导致ORA-600错误的原因。Oracle在删除表空间的时候发现有表存在，但是根据段信息又找不到对应的记录，导致删除无法完成，从而引发了这个错误。
至于数据字典不一致的产生应该是测试环境通过imp导入tab$引起的，对于测试环境而言，这个错误很容易清除掉，直接删除不一致的记录即可，但是对于产品环境而言，不推荐这种方式：
