（1）ASH报告生成脚本如下所示，根据提示输入相应的值即可获得ASH报告。
l Linux：@?/rdbms/admin/ashrpt.sql
l Windows：@?rdbmsadminashrpt.sql
（2）使用OEM，可以在性能页，单击“运行ASH报告”按钮生成ASH报告，由于OEM生产用的相对比较少，这里就不讨论了。
（3）可以利用存储过程DBMS_WORKLOAD_REPOSITORY.ASH_REPORT_HTML()来获取ASH报告的文本内容，然后将文本内容拷贝到文本文件中，最后修改文本文件的后缀名为html即可打开html格式的ASH报告。例如取3116-3117之间的快照：
代码语言：javascript复制SELECT * FROM TABLE(DBMS_WORKLOAD_REPOSITORY.ASH_REPORT_HTML(3424884828,1, (SELECT A.END_INTERVAL_TIME FROM DBA_HIST_ASH_SNAPSHOT A WHERE A.SNAP_ID =3116) , (SELECT A.END_INTERVAL_TIME FROM DBA_HIST_ASH_SNAPSHOT A WHERE A.SNAP_ID =3117)));
可以利用如下的脚本来批量生成要运行的存储过程：
代码语言：javascript复制SELECT D.SNAP_ID,
D.DBID,
D.INSTANCE_NUMBER,
(SELECT (NB.SNAP_INTERVAL)
FROM DBA_HIST_WR_CONTROL NB) SNAP_INTERVAL,
(SELECT (NB.RETENTION)
FROM DBA_HIST_WR_CONTROL NB) RETENTION,
TO_CHAR(D.STARTUP_TIME, 'YYYY-MM-DD HH24:MI:SS.FF') STARTUP_TIME,
TO_CHAR(D.BEGIN_INTERVAL_TIME, 'YYYY-MM-DD HH24:MI:SS.FF') BEGIN_INTERVAL_TIME,
TO_CHAR(D.END_INTERVAL_TIME, 'YYYY-MM-DD HH24:MI:SS.FF') END_INTERVAL_TIME,
(D.FLUSH_ELAPSED) FLUSH_ELAPSED,
D.SNAP_LEVEL,
D.ERROR_COUNT,
D.SNAP_FLAG,
'SELECT * FROM TABLE(DBMS_WORKLOAD_REPOSITORY.ASH_REPORT_HTML(' ||
D.DBID || ',' || D.INSTANCE_NUMBER ||
', (SELECT A.END_INTERVAL_TIME FROM DBA_HIST_ASH_SNAPSHOT A WHERE A.SNAP_ID =' ||
(D.SNAP_ID - 1) ||
') , (SELECT A.END_INTERVAL_TIME FROM DBA_HIST_ASH_SNAPSHOT A WHERE A.SNAP_ID =' || (D.SNAP_ID) || ')));' ASH_REPORT
FROM DBA_HIST_ASH_SNAPSHOT D
ORDER BY D.SNAP_ID DESC;
