Oracle Internet Directory用自定义SCHEMA建立条目出错

jiameng 2004-09-21 10:59:52
我自定义了属性apo1,apo2,
自定义方案（schema）aobj1,
再建条目时，选择自定义的对象类为aobj1，输入二项强制属性之后就会报错“错误代码=112”，
甚至有时取消后，再去点其它的操作，一点确定就会报同样的错误"错误代码=112"。

ORACLE常用命令 一、ORACLE的启动和关闭 1、在单机环境下 要想启动或关闭ORACLE系统必须首先切换到ORACLE用户，如下 su - oracle a、启动ORACLE系统 oracle>svrmgrl SVRMGR>connect internal SVRMGR>startup SVRMGR>quit b、关闭ORACLE系统 oracle>svrmgrl SVRMGR>connect internal SVRMGR>shutdown SVRMGR>quit 启动oracle9i数据库命令： $ sqlplus /nolog SQL*Plus: Release 9.2.0.1.0 - Production on Fri Oct 31 13:53:53 2003 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved. SQL> connect / as sysdba Connected to an idle instance. SQL> startup^C SQL> startup ORACLE instance started. 2、在双机环境下 要想启动或关闭ORACLE系统必须首先切换到root用户，如下 su － root a、启动ORACLE系统 hareg －y oracle b、关闭ORACLE系统 hareg －n oracle Oracle数据库有哪几种启动方式 说明： 有以下几种启动方式： 1、startup nomount 非安装启动，这种方式启动下可执行：重建控制文件、重建数据库 读取init.ora文件，启动instance，即启动SGA和后台进程，这种启动只需要init.ora文件。 2、startup mount dbname 安装启动，这种方式启动下可执行： 数据库日志归档、 数据库介质恢复、 使数据文件联机或脱机， 重新定位数据文件、重做日志文件。 执行“nomount”，然后打开控制文件，确认数据文件和联机日志文件的位置， 但此时不对数据文件和日志文件进行校验检查。 3、startup open dbname 先执行“nomount”，然后执行“mount”，再打开包括Redo log文件在内的所有数据库文件， 这种方式下可访问数据库中的数据。 4、startup，等于以下三个命令 startup nomount alter database mount alter database open 5、startup restrict 约束方式启动 这种方式能够启动数据库，但只允许具有一定特权的用户访问 非特权用户访问时，会出现以下提示： ERROR： ORA-01035: ORACLE 只允许具有 RESTRICTED SESSION 权限的用户使用 6、startup force 强制启动方式 当不能关闭数据库时，可以用startup force来完成数据库的关闭 先关闭数据库，再执行正常启动数据库命令 7、startup pfile=参数文件名 带初始化参数文件的启动方式 先读取参数文件，再按参数文件中的设置启动数据库 例：startup pfile=E:Oracleadminoradbpfileinit.ora 8、startup EXCLUSIVE 二、用户如何有效地利用数据字典 　ORACLE的数据字典是数据库的重要组成部分之一，它随着数据库的产生而产生, 随着数据库的变化而变化, 体现为sys用户下的一些表和视图。数据字典名称是大写的英文字符。 数据字典里存有用户信息、用户的权限信息、所有数据对象信息、表的约束条件、统计分析数据库的视图等。 我们不能手工修改数据字典里的信息。 　　很多时候，一般的ORACLE用户不知道如何有效地利用它。 　　dictionary　　　全部数据字典表的名称和解释，它有一个同义词dict dict_column　　 全部数据字典表里字段名称和解释 如果我们想查询跟索引有关的数据字典时，可以用下面这条SQL语句: SQL>select * from dictionary where instr(comments,'index')>0; 如果我们想知道user_indexes表各字段名称的详细含义，可以用下面这条SQL语句: SQL>select column_name,comments from dict_columns where table_name='USER_INDEXES'; 依此类推，就可以轻松知道数据字典的详细名称和解释，不用查看ORACLE的其它文档资料了。 下面按类别列出一些ORACLE用户常用数据字典的查询使用方法。 1、用户 查看当前用户的缺省表空间 SQL>select username,default_tablespace from user_users; 查看当前用户的角色 SQL>select * from user_role_privs; 查看当前用户的系统权限和表级权限 SQL>select * from user_sys_privs; SQL>select * from user_tab_privs; 2、表 查看用户下所有的表 SQL>select * from user_tables; 查看名称包含log字符的表 SQL>select object_name,object_id from user_objects where instr(object_name,'LOG')>0; 查看某表的创建时间 SQL>select object_name,created from user_objects where object_name=upper('&table_name'); 查看某表的大小 SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments where segment_name=upper('&table_name'); 查看放在ORACLE的内存区里的表 SQL>select table_name,cache from user_tables where instr(cache,'Y')>0; 3、索引 查看索引个数和类别 SQL>select index_name,index_type,table_name from user_indexes order by table_name; 查看索引被索引的字段 SQL>select * from user_ind_columns where index_name=upper('&index_name'); 查看索引的大小 SQL>select sum(bytes)/(1024*1024) as "size(M)" from user_segments where segment_name=upper('&index_name'); 4、序列号 查看序列号，last_number是当前值 SQL>select * from user_sequences; 5、视图 查看视图的名称 SQL>select view_name from user_views; 查看创建视图的select语句 SQL>set view_name,text_length from user_views; SQL>set long 2000; 说明：可以根据视图的text_length值设定set long 的大小 SQL>select text from user_views where view_name=upper('&view_name'); 6、同义词 查看同义词的名称 SQL>select * from user_synonyms; 7、约束条件 查看某表的约束条件 SQL>select constraint_name, constraint_type,search_condition, r_constraint_name from user_constraints where table_name = upper('&table_name'); SQL>select c.constraint_name,c.constraint_type,cc.column_name from user_constraints c,user_cons_columns cc where c.owner = upper('&table_owner') and c.table_name = upper('&table_name') and c.owner = cc.owner and c.constraint_name = cc.constraint_name order by cc.position; 8、存储函数和过程 查看函数和过程的状态 SQL>select object_name,status from user_objects where object_type='FUNCTION'; SQL>select object_name,status from user_objects where object_type='PROCEDURE'; 查看函数和过程的源代码 SQL>select text from all_source where owner=user and name=upper('&plsql_name'); 三、查看数据库的SQL 1、查看表空间的名称及大小 select t.tablespace_name, round(sum(bytes/(1024*1024)),0) ts_size from dba_tablespaces t, dba_data_files d where t.tablespace_name = d.tablespace_name group by t.tablespace_name; 2、查看表空间物理文件的名称及大小 select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name; 3、查看回滚段名称及大小 select segment_name, tablespace_name, r.status, (initial_extent/1024) InitialExtent,(next_extent/1024) NextExtent, max_extents, v.curext CurExtent From dba_rollback_segs r, v$rollstat v Where r.segment_id = v.usn(+) order by segment_name ; 4、查看控制文件 select name from v$controlfile; 5、查看日志文件 select member from v$logfile; 6、查看表空间的使用情况 select sum(bytes)/(1024*1024) as free_space,tablespace_name from dba_free_space group by tablespace_name; SELECT A.TABLESPACE_NAME,A.BYTES TOTAL,B.BYTES USED, C.BYTES FREE, (B.BYTES*100)/A.BYTES "% USED",(C.BYTES*100)/A.BYTES "% FREE" FROM SYS.SM$TS_AVAIL A,SYS.SM$TS_USED B,SYS.SM$TS_FREE C WHERE A.TABLESPACE_NAME=B.TABLESPACE_NAME AND A.TABLESPACE_NAME=C.TABLESPACE_NAME; 7、查看数据库库对象 select owner, object_type, status, count(*) count# from all_objects group by owner, object_type, status; 8、查看数据库的版本 Select version FROM Product_component_version Where SUBSTR(PRODUCT,1,6)='Oracle'; 9、查看数据库的创建日期和归档方式 Select Created, Log_Mode, Log_Mode From V$Database; 四、ORACLE用户连接的管理 用系统管理员，查看当前数据库有几个用户连接： SQL> select username,sid,serial# from v$session; 如果要停某个连接用 SQL> alter system kill session 'sid,serial#'; 如果这命令不行,找它UNIX的进程数 SQL> select pro.spid from v$session ses,v$process pro where ses.sid=21 and ses.paddr=pro.addr; 说明：21是某个连接的sid数 然后用 kill 命令杀此进程号。 五、SQL*PLUS使用 a、近入SQL*Plus $sqlplus 用户名/密码 退出SQL*Plus SQL>exit b、在sqlplus下得到帮助信息 列出全部SQL命令和SQL*Plus命令 SQL>help 列出某个特定的命令的信息 SQL>help 命令名 c、显示表结构命令DESCRIBE SQL>DESC 表名 d、SQL*Plus中的编辑命令 显示SQL缓冲区命令 SQL>L 修改SQL命令 首先要将待改正行变为当前行 SQL>n 用CHANGE命令修改内容 SQL>c/旧/新 重新确认是否已正确 SQL>L 使用INPUT命令可以在SQL缓冲区中增加一行或多行 SQL>i SQL>输入内容 e、调用外部系统编辑器 SQL>edit 文件名 可以使用DEFINE命令设置系统变量EDITOR来改变文本编辑器的类型，在login.sql文件中定义如下一行 DEFINE_EDITOR=vi f、运行命令文件 SQL>START test SQL>@test 常用SQL*Plus语句 a、表的创建、修改、删除 创建表的命令格式如下： create table 表名 （列说明列表）； 为基表增加新列命令如下： ALTER TABLE 表名 ADD （列说明列表） 例：为test表增加一列Age，用来存放年龄 sql>alter table test add （Age number(3)）； 修改基表列定义命令如下： ALTER TABLE 表名 MODIFY （列名 数据类型） 例：将test表中的Count列宽度加长为10个字符 sql>alter atble test modify （County char(10)）； b、将一张表删除语句的格式如下： DORP TABLE 表名； 例：表删除将同时删除表的数据和表的定义 sql>drop table test c、表空间的创建、删除 六、ORACLE逻辑备份的SH文件 完全备份的SH文件：exp_comp.sh rq=` date +"%m%d" ` su - oracle -c "exp system/manager full=y inctype=complete file=/oracle/export/db_comp$rq.dmp" 累计备份的SH文件：exp_cumu.sh rq=` date +"%m%d" ` su - oracle -c "exp system/manager full=y inctype=cumulative file=/oracle/export/db_cumu$rq.dmp" 增量备份的SH文件: exp_incr.sh rq=` date +"%m%d" ` su - oracle -c "exp system/manager full=y inctype=incremental file=/oracle/export/db_incr$rq.dmp" root用户crontab文件 /var/spool/cron/crontabs/root增加以下内容 0 2 1 * * /oracle/exp_comp.sh 30 2 * * 0-5 /oracle/exp_incr.sh 45 2 * * 6 /oracle/exp_cumu.sh 当然这个时间表可以根据不同的需求来改变的，这只是一个例子。 七、ORACLE 常用的SQL语法和数据对象 一.数据控制语句 (DML) 部分 1.INSERT (往数据表里插入记录的语句) INSERT INTO 表名(字段名1, 字段名2, ……) VALUES ( 值1, 值2, ……); INSERT INTO 表名(字段名1, 字段名2, ……) SELECT (字段名1, 字段名2, ……) FROM 另外的表名; 字符串类型的字段值必须用单引号括起来, 例如: ’GOOD DAY’ 如果字段值里包含单引号’ 需要进行字符串转换, 我们把它替换成两个单引号''. 字符串类型的字段值超过定义的长度会出错, 最好在插入前进行长度校验. 日期字段的字段值可以用当前数据库的系统时间SYSDATE, 精确到秒 或者用字符串转换成日期型函数TO_DATE(‘2001-08-01’,’YYYY-MM-DD’) TO_DATE()还有很多种日期格式, 可以参看ORACLE DOC. 年-月-日 小时:分钟:秒 的格式YYYY-MM-DD HH24:MI:SS INSERT时最大可操作的字符串长度小于等于4000个单字节, 如果要插入更长的字符串, 请考虑字段用CLOB类型, 方法借用ORACLE里自带的DBMS_LOB程序包. INSERT时如果要用到从1开始自动增长的序列号, 应该先建立一个序列号 CREATE SEQUENCE 序列号的名称 (最好是表名+序列号标记) INCREMENT BY 1 START WITH 1 MAXVALUE 99999 CYCLE NOCACHE; 其中最大的值按字段的长度来定, 如果定义的自动增长的序列号 NUMBER(6) , 最大值为999999 INSERT 语句插入这个字段值为: 序列号的名称.NEXTVAL 2.DELETE (删除数据表里记录的语句) DELETE FROM表名 WHERE 条件; 注意：删除记录并不能释放ORACLE里被占用的数据块表空间. 它只把那些被删除的数据块标成unused. 如果确实要删除一个大表里的全部记录, 可以用 TRUNCATE 命令, 它可以释放占用的数据块表空间 TRUNCATE TABLE 表名; 此操作不可回退. 3.UPDATE (修改数据表里记录的语句) UPDATE表名 SET 字段名1=值1, 字段名2=值2, …… WHERE 条件; 如果修改的值N没有赋值或定义时, 将把原来的记录内容清为NULL, 最好在修改前进行非空校验; 值N超过定义的长度会出错, 最好在插入前进行长度校验.. 注意事项: A. 以上SQL语句对表都加上了行级锁, 确认完成后, 必须加上事物处理结束的命令 COMMIT 才能正式生效, 否则改变不一定写入数据库里. 如果想撤回这些操作, 可以用命令 ROLLBACK 复原. B. 在运行INSERT, DELETE 和 UPDATE 语句前最好估算一下可能操作的记录范围, 应该把它限定在较小 (一万条记录) 范围内,. 否则ORACLE处理这个事物用到很大的回退段. 程序响应慢甚至失去响应. 如果记录数上十万以上这些操作, 可以把这些SQL语句分段分次完成, 其间加上COMMIT 确认事物处理. 二.数据定义 (DDL) 部分 1.CREATE (创建表, 索引, 视图, 同义词, 过程, 函数, 数据库链接等) ORACLE常用的字段类型有 CHAR 固定长度的字符串 VARCHAR2 可变长度的字符串 NUMBER(M,N) 数字型M是位数总长度, N是小数的长度 DATE 日期类型 创建表时要把较小的不为空的字段放在前面, 可能为空的字段放在后面 创建表时可以用中文的字段名, 但最好还是用英文的字段名 创建表时可以给字段加上默认值, 例如 DEFAULT SYSDATE 这样每次插入和修改时, 不用程序操作这个字段都能得到动作的时间 创建表时可以给字段加上约束条件 例如 不允许重复 UNIQUE, 关键字 PRIMARY KEY 2.ALTER (改变表, 索引, 视图等) 改变表的名称 ALTER TABLE 表名1 TO 表名2; 在表的后面增加一个字段 ALTER TABLE表名 ADD 字段名 字段名描述; 修改表里字段的定义描述 ALTER TABLE表名 MODIFY字段名 字段名描述; 给表里的字段加上约束条件 ALTER TABLE 表名 ADD CONSTRAINT 约束名 PRIMARY KEY (字段名); ALTER TABLE 表名 ADD CONSTRAINT 约束名 UNIQUE (字段名); 把表放在或取出数据库的内存区 ALTER TABLE 表名 CACHE; ALTER TABLE 表名 NOCACHE; 3.DROP (删除表, 索引, 视图, 同义词, 过程, 函数, 数据库链接等) 删除表和它所有的约束条件 DROP TABLE 表名 CASCADE CONSTRAINTS; 4.TRUNCATE (清空表里的所有记录, 保留表的结构) TRUNCATE 表名; 三.查询语句 (SELECT) 部分 SELECT字段名1, 字段名2, …… FROM 表名1, [表名2, ……] WHERE 条件; 字段名可以带入函数 例如: COUNT(*), MIN(字段名), MAX(字段名), AVG(字段名), DISTINCT(字段名), TO_CHAR(DATE字段名,'YYYY-MM-DD HH24:MI:SS') NVL(EXPR1, EXPR2)函数 解释: IF EXPR1=NULL RETURN EXPR2 ELSE RETURN EXPR1 DECODE(AA﹐V1﹐R1﹐V2﹐R2....)函数 解释: IF AA=V1 THEN RETURN R1 IF AA=V2 THEN RETURN R2 ..… ELSE RETURN NULL LPAD(char1,n,char2)函数 解释: 字符char1按制定的位数n显示，不足的位数用char2字符串替换左边的空位 字段名之间可以进行算术运算 例如: (字段名1*字段名1)/3 查询语句可以嵌套 例如: SELECT …… FROM (SELECT …… FROM表名1, [表名2, ……] WHERE 条件) WHERE 条件2; 两个查询语句的结果可以做集合操作 例如: 并集UNION(去掉重复记录), 并集UNION ALL(不去掉重复记录), 差集MINUS, 交集INTERSECT 分组查询 SELECT字段名1, 字段名2, …… FROM 表名1, [表名2, ……] GROUP BY字段名1 [HAVING 条件] ; 两个以上表之间的连接查询 SELECT字段名1, 字段名2, …… FROM 表名1, [表名2, ……] WHERE 表名1.字段名 = 表名2. 字段名 [ AND ……] ; SELECT字段名1, 字段名2, …… FROM 表名1, [表名2, ……] WHERE 表名1.字段名 = 表名2. 字段名(+) [ AND ……] ; 有(+)号的字段位置自动补空值 查询结果集的排序操作, 默认的排序是升序ASC, 降序是DESC SELECT字段名1, 字段名2, …… FROM 表名1, [表名2, ……] ORDER BY字段名1, 字段名2 DESC; 字符串模糊比较的方法 INSTR(字段名, ‘字符串’)>0 字段名 LIKE ‘字符串%’ [‘%字符串%’] 每个表都有一个隐含的字段ROWID, 它标记着记录的唯一性. 四.ORACLE里常用的数据对象 (SCHEMA) 1.索引 (INDEX) CREATE INDEX 索引名ON 表名 ( 字段1, [字段2, ……] ); ALTER INDEX 索引名 REBUILD; 一个表的索引最好不要超过三个 (特殊的大表除外), 最好用单字段索引, 结合SQL语句的分析执行情况, 也可以建立多字段的组合索引和基于函数的索引 ORACLE8.1.7字符串可以索引的最大长度为1578 单字节 ORACLE8.0.6字符串可以索引的最大长度为758 单字节 2.视图 (VIEW) CREATE VIEW 视图名AS SELECT …. FROM …..; ALTER VIEW视图名 COMPILE; 视图仅是一个SQL查询语句, 它可以把表之间复杂的关系简洁化. 3.同义词 (SYNONMY) CREATE SYNONYM同义词名FOR 表名; CREATE SYNONYM同义词名FOR 表名@数据库链接名; 4.数据库链接 (DATABASE LINK) CREATE DATABASE LINK数据库链接名CONNECT TO 用户名 IDENTIFIED BY 密码 USING ‘数据库连接字符串’; 数据库连接字符串可以用NET8 EASY CONFIG或者直接修改TNSNAMES.ORA里定义. 数据库参数global_name=true时要求数据库链接名称跟远端数据库名称一样 数据库全局名称可以用以下命令查出 SELECT * FROM GLOBAL_NAME; 查询远端数据库里的表 SELECT …… FROM 表名@数据库链接名; 五.权限管理 (DCL) 语句 1.GRANT 赋于权限 常用的系统权限集合有以下三个: CONNECT(基本的连接), RESOURCE(程序开发), DBA(数据库管理) 常用的数据对象权限有以下五个: ALL ON 数据对象名, SELECT ON 数据对象名, UPDATE ON 数据对象名, DELETE ON 数据对象名, INSERT ON 数据对象名, ALTER ON 数据对象名 GRANT CONNECT, RESOURCE TO 用户名; GRANT SELECT ON 表名 TO 用户名; GRANT SELECT, INSERT, DELETE ON表名 TO 用户名1, 用户名2; 2.REVOKE 回收权限 REVOKE CONNECT, RESOURCE FROM 用户名; REVOKE SELECT ON 表名 FROM 用户名; REVOKE SELECT, INSERT, DELETE ON表名 FROM 用户名1, 用户名2; 查询数据库中第63号错误： select orgaddr,destaddr from sm_histable0116 where error_code='63'; 查询数据库中开户用户最大提交和最大下发数： select MSISDN,TCOS,OCOS from ms_usertable； 查询数据库中各种错误代码的总和： select error_code,count(*) from sm_histable0513 group by error_code order by error_code; 查询报表数据库中话单统计种类查询。 select sum(Successcount) from tbl_MiddleMt0411 where ServiceType2=111 select sum(successcount),servicetype from tbl_middlemt0411 group by servicetype 原文地址：http://www.cnoug.org/viewthread.php?tid=60293 //创建一个控制文件命令到跟踪文件 alter database backup controlfile to trace;
