ORACLE数据库ORA-00257解决

kuuyee — Wed, 15 May 2013 02:13:00 GMT

今天数据库突然连不上了，报ORA-00257错误�Q�空间不��错误）�Q�通过查找资料�Q�绝大部分说�q�是�׃��Archivelog归档日志太多�Q�占用了全部的硬盘剩余空间导致的�Q�通过��单删除日志或加大存储�I�间��p��够解冟�?/span>

首先�q�入oracle用户�Q��?strong>rman工具执行命��orman target/�Q?/p>

oracle@test-idm-db01$ rman target/  

Recovery Manager: Release 11.2.0.1.0 - Production on Wed May 15 09:29:06 2013  

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.  
RMAN-00571: =========================================================== 
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== 
RMAN-00571: =========================================================== 
RMAN-00554: initialization of internal recovery manager package failed 
RMAN-04005: error from target database: 
ORA-01031: insufficient privileges

竟然报错了，如果你的�I�间100%一点剩余都没有�Q�那么就会报�q�个错，只能惛_��法让你的�pȝ��腑և�一点空��_��哪怕几癑օ��Q�然后重启数据库应该��可以登陆dba了�?/p>

重启数据库，再次rman

oracle@test-idm-db01$ rman target/  

Recovery Manager: Release 11.2.0.1.0 - Production on Wed May 15 09:29:40 2013  

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.  

connected to target database: IDM_TEST (DBID=4064060693)

现在删除Archivelog归档文�g�Q�执行下面的命��o来删除最�q?天的归档�Q?/p>

RMAN> DELETE ARCHIVELOG FROM TIME 'SYSDATE-7';

也可以只保留最�q?天的�Q�其余的都删除：

RMAN> DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-7';

但是�q�一�D�|��间你的日志还是回满，对于开发环境这��L��归档功能其实没什么必要，��d��解决办法是关闭这个功能，用dba登陆oracle�Q?/p>

sqlplus / as sysdba;

然后执行下面的命令：

SQL> alter database flashback off;

然后重启数据库就O(ji��n)K了！

在RHEL5.5上安装PostgreSql92

kuuyee — Tue, 09 Apr 2013 07:55:00 GMT

RHEL5.5默认的源里没有postgresql9的包�Q�需要下载源。下载地址 �Q?a style="color: #0088cc; text-decoration: none;">http://yum.postgresql.org/9.2/redhat/rhel-5-x86_64/pgdg-redhat92-9.2-7.noarch.rpm

然后安装�?/p>

rpm -ivh pgdg-redhat92-9.2-7.noarch.rpm

最后安装postgresql92

yum install postgresql92 postgresql92-server postgresql92-devel

初始化数据库

service postgresql-9.2 initdb Initializing database:                                     [  OK  ]

启动数据�?/p>

/etc/init.d/postgresql-9.2 start Starting postgresql-9.2 service:                           [  OK  ]

查看数据状�?/p>

netstat -nutlap | grep post tcp        0      0 127.0.0.1:5432              0.0.0.0:*                   LISTEN      21627/postmaster     udp        0      0 127.0.0.1:12823             127.0.0.1:12823             ESTABLISHED 21627/postmaster

ORACLE 11g在Linux下手工配�|�EM

kuuyee — Thu, 05 Apr 2012 03:08:00 GMT

使用OTK工具安装的Oracle默认没有配置EM�Q�下面记录下配置和启动过�E?

首先创徏EM�Q�执行下面的命��o

$ emca -config dbcontrol db -repos recreate

我第一�ơ运行报如下错误�Q?br />

Mar 31, 2012 4:16:06 PM oracle.sysman.emcp.EMReposConfig createRepository

解决办法

使用SYS用户��d��sqlplus�Q�然后执行下面的语句�Q?/p>

 SQL> SELECT * FROM DBA_DATA_FILES where TABLESPACE_NAME = 'SYSTEM'; 
FILE_NAME     FILE_ID TABLESPACE_NAME

SYSTEM

然后新定义个�I�间文�gwcdb_system_02.dbf�Q�注意不要重�?/p>

然后新定义个�I�间文�g*wcdb_system_02.dbf*�Q�注意不要重�?/p>

SQL> ALTER TABLESPACE SYSTEM ADD DATAFILE '/data01/rdbms/wcdb/datafile/wcdb_system_02.dbf' SIZE 500M; Tablespace altered.

然后再次执行EM创徏成功�Q?/p>

EM的访问地址�Q?a href="https://host:1158/em" style="color: fuchsia; ">https://localhost:1158/em

删除一个EM资料�?/strong>

$ emca -repos drop

配置数据库的 Database Control

$ emca -config dbcontrol db

删除数据库的 Database Control配置

$ emca -deconfig dbcontrol db

重新配置db control的端口，默认端口�?158

$ emca -reconfig ports $ emca -reconfig ports -dbcontrol_http_port 1160 $ emca -reconfig ports -agent_port 3940

先设 �|�ORACLE_SID环境变量�?启动EM console服务

$ emctl start dbconsole

先设�|?ORACLE_SID环境变量�?停止EM console服务

$ emctl stop dbconsole

先设�|�ORACLE_SID�?境变量后,查看EM console服务的状�?/strong>

$ emctl status dbconsole

开启Mysql�q�程讉K��

kuuyee — Wed, 22 Jul 2009 05:52:00 GMT
Mysql默认是不可以通过�q�程机器讉K��?通过下面的配�|�可以开启远�E�访�?
我的Mysql环境是ubuntu+mysql5
1.修改/etc/mysql/my.conf,修改bind-address,指定为本机实际IP地址,你的my.con修改完大概是如下的样�?br />
[mysqld]
#
# * Basic Settings
#
default-character-set=utf8
default-storage-engine=INNODB

bind-address    = 192.168.1.107

user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
language        = /usr/share/mysql/english
skip-external-locking

2.用root登陆mysql执行如下命��o

grant all on sonardb.* to sonar@'%' identified by '123456';
grant all on sonardb.* to sonar@localhost identified by '123456';

sonardb替换��Z��惌��问的数据库名,sonar是你的想使用的用户名,123456替换��Z��的密�?�q�样��开启了�q�程讉K��功能.

Ubuntu下更改Mysql默认字符�?

kuuyee — Wed, 22 Jul 2009 03:01:00 GMT
在ubuntu安装Mysql Server比较��?一条命令就可以搞定,如下:

sudo apt-get install mysql-server

但是用apt-get安装mysql不能讄��默认字符�?可能是我不明白怎么�?安装完默认字�W�集是latin1,可以��d��mysql后用status命��o查看,昄��内容如下:

root@ubuntu-vm:/home/kuuyee# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.0.51a-3ubuntu5.4 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> status

--------------

解决办法��是更改/etc/mysql/my.cnf文�g,在[mysqld]和[mysql]下添加如下内�?

[mysqld]
default-character-set=utf8
default-storage-engine=INNODB

[mysql]
default-character-set=utf8

然后重启mysql server卛_��,命��o如下:

sudo /etc/init.d/mysql　restart

然后再查看一下status,呵呵!字符集变为utf-8�?

cmd下切换到 mysql 安装目录
�?br /> d:/mysql/bin
前提�Q�mysql用户root密码为空.
输入 mysql -u root mysql
mysql> 状态下输入 update user set password=password('新密�?) where user='root';
回显
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0
mysql> 状态下输入 FLUSH PRIVILEGES;
回显
Query OK, 0 rows affected (0.00 sec)
mysql> 状态下输入 quit
退�?sql

注意每个命��o后都要加上一个分�?";"
mysql 才开始执行该行命�?br /> 而第二个指��o会让已蝲入记忆体�?mysql �pȝ��资料库更�?

重�v mysql .
在更�?root 密码后，以后要与 MySQL �q�接的方法�ؓ�Q?

mysql -u root -p 新密�?
