Oracle university建议用户若仍由考取10g ocm的计划,那么应当在2015年3月前完成。
对于国内的一些有WDP或者没有WDP资质的培训机构而言,这并不是什么好消息,由于10g ocm考取的整个过程已经非常熟悉(包括考试的每一道题目和细节环节),而11g OCM对于急需仅仅想获得一个Paper证书的学员来说并不友好,所以10g ocm retire 将给其批量生产ocm的生意带来少量麻烦,当然在利益面前这一切都会被克服的,我们要相信他们的能力!
群内讨论,为什么ORACLE 10g都过了extended support,但10g ocm还是考试的主力?只能说10g ocm这个大蛋糕还没被彻底切完,而且各大第三方培训机构对11g ocm的题库还不熟悉,反正10g的钱还能挣着,就无所谓那么急要给考试也升个级了。或许可以在国内看到这种现象,市面上没人用10g了,但是大家还在考10g

方法:1、利用“select*from user_indexes where table_name=表名”语句查询表中索引;2、利用“select*from all_indexes where table_name=表名”语句查询所有索引。

oracle asm指的是“自动存储管理”,是一种卷管理器,可自动管理磁盘组并提供有效的数据冗余功能;它是做为单独的Oracle实例实施和部署。asm的优势:1、配置简单、可最大化推动数据库合并的存储资源利用;2、支持BIGFILE文件等。

在oracle中,可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角;“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符,只有当数据库字符集同时包含多字节和单字节字符的时候有效。

在Oracle中,可利用lsnrctl命令查询端口号,该命令是Oracle的监听命令;在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态,语法为“lsnrctl status”,结果PORT后的内容就是端口号。

在oracle中,可以利用“drop sequence sequence名”来删除sequence;sequence是自动增加数字序列的意思,也就是序列号,序列号自动增加不能重置,因此需要利用drop sequence语句来删除序列。

在oracle中,可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。

方法:1、利用“LOWER(字段值)”将字段转为小写,或者利用“UPPER(字段值)”将字段转为大写;2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”,当参数设置为“i”时,说明进行匹配不区分大小写。

方法:1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数;2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
