AIX 5.3

11.1.0.7

sysaux快满了(一共3G)，其中AWR的信息占了1.5G左右

alert 中：

ORA-1688: unable to extend table SYS.WRH$_ACTIVE_SESSION_HISTORY partition WRH$_ACTIVE_1153364305_5522 by 4096 in                 tablespace SYSAUX

所以想删除一部快照

但奇怪的是

SQL> select count(*) from dba_hist_snapshot;

COUNT(*)

----------

0

怎么能没有快照呢，我手工生成快照又报错：

SQL> exec DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT();

BEGIN DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT(); END;

ERROR at line 1:

我又想把保留时间减小点

SQL> select * from dba_hist_wr_control;

在网上查了查，有篇文章说是跟baseline设置有关，可我这边还是没有记录

SQL> select count(*) from dba_hist_baseline;

真不知道oracle他在想什么呢，

各位大虾请指教一二

我现在想把AWR占用的空间腾出来先，SYSAUX满了毕竟不是什么好事

另外，这个还是挺奇怪的，是遇到BUG了吗，还是我哪里忽略了，怎么就不能生成快照了呢，以前的快照也没有，一个也没有

好晕。
