ODA入门指南总结
如果要和Oracle数据库的文档进行比较,这篇文档类似管理员手册。 由于ODA是一体机,既包含了软件也包括了硬件。因此文档虽然仍然是以软件的描述为主,但是仍然包括了一些硬件的描述,比如网络接口、前后面板警示灯的介绍等等。 ODA本身的管理就很简单,因此这篇文档已经涵盖了ODA日常操作维护的绝大部分内容,包括部署ODA前的准备、ODA的安装、ODA的维护、ODA的高可用以及ODA的故障诊断等等。如果对ODA感兴趣或者已经部署了ODA环境,那么这篇文档是最好的ODA入门手册。

TNSNAMES配置中空格导致的bug(二)
之前一直认为这是Oracle的一个bug,直到前一段时间通读网络服务参考手册时,才发现问题的真相。 TNSNAMES配置中空格导致的bug:http://yangtingkun.itpub.net/post/468/487506 当时测试发现,只要在SERVICE_NAME下面的一行缺少空格,就会导致错误的产生: TEST08 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.25.13.229)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = test08) ) )TEST08 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.25.13.229)(PORT = 1521)) (CONNECT_DATA = … Continue reading
收集STATSPACK的级别
虽然AWR功能已经完全可以替代STATSPACK的功能,但是目前存在的9i的数据库还有不少,而且却是发现有不少人不了解如何更改STATSPACK的级别。 STATSPACK默认是LEVEL 5收集,而LEVEL 5收集的数据是不包括执行计划的,因此对于关注SQL性能的情况,至少需要调整到LEVEL 6,下面是检查和调整STATSPACK收集等级的方法,比较简单,就不多解释了: SQL> EXEC statspack.snap PL/SQL PROCEDURE successfully completed. SQL> SELECT snap_id, dbid, snap_level FROM stats$snapshot; SNAP_ID DBID SNAP_LEVEL ———- ———- ———- 1 1258229964 5 1 ROW selected. SQL> EXEC statspack.snap(i_snap_level => 6) PL/SQL PROCEDURE successfully completed. … Continue reading
