在RHEL4上安装OracleDatabase10gR2(上)
在RHEL4上安装OracleDatabase10gR2(上)分步骤教你在window虚拟机的Linu某平台上安装Oracle10g,从安装虚拟机开始一直到安装Oracle10g,每部够有截图与说明。
前言Linu某最初的一些版本，主要用途是作為開發平台工作站及桌上型電腦系統，因此缺乏對於大型系統的支援能力，所以比較不適合當作伺服器系統。
但是自從1999年發表2.2的kernel之後不僅支援多重處理器系統，也包括支援更強健的I/O能力；直到2001年的2.4kernel發表之後，更提供了一個穩定、高效能的作業系統，並且也支援了更大量的記憶體。
所以大多數的硬體廠商，也開始都提供了對Linu某伺服器的驅動程式與支援服務。
從今以後Linu某系統不管是效能和穩定度上都急起直追昂貴的UNI某系統。
除了有硬體大廠支援外，Linu某更擁有製造供應商的如虎添翼加持，如Oracle的強力支援最為後盾。
現今，Oracle所有的主力產品已經都可支援在Linu某作業系統上。
Oracle最初是針對UNI某作業系統而設計的，因此它的架構相當適合由UNI某延伸發展而來的Linu某作業系統。
雖然Oracle也能夠在其他的作業系統的架構上執行，不過不管是效能和穩定度的表現上，UNI某-Like作業系統的架構仍然是最適合它。
擁有Oracle10g與Linu某，將代表著擁有當前最先進的關聯式資料庫管理系統，且運作於最先進最低成本的作業系統上。
測試軟體之取得方式要在RedHatEnterprieLinu某4（RHEL4）上安裝OracleDatabae10gR2，分成三個部份：3.安裝OracleDatabae10gR2（）以上所有下載的軟體其授權方式為“(程式開發者授權＂DeveloperLicene)，雖然具備完整版的功能，但是您只能運用於開發測試或是進行評估，千萬不能進行商業用途！分步骤教你在window虚拟机的Linu某平台上安装Oracle10g,从安装虚拟机开始一直到安装Oracle10g,每部够有截图与说明。

Oracle Database 10g Express
Oracle Database 10g ExpressThis tutorial prepares the Oracle Database 10g Express Edition Developer to perform common development and administrative tasks of Oracle Database 10g Express Edition.ObjectivesAfter taking this tutorial, you should be able to:•Install Oracle Database 10g Express Edition•Access the Oracle Database Home Page•Manage Database Objects•Access and Manipulate DataWhat is Oracle Database 10g Express Edition?Oracle Database 10g Express Edition (Oracle Database XE) is a free, downloadable version of the world's most capable relational database.Oracle Database XE is easy to install and easy to manage.With Oracle Database XE, you use the Database Home Page, an intuitive browser-based interface, to administer the database; create tables, views, and other schema objects; import, export, and view table data; run queries and SQL scripts; and generate reports.Oracle Database XE includes Oracle HTML DB 2.1, a declarative, graphical development environment for creating database-centric Web applications. In addition to HTML DB 2.1, you can use popular Oracle and third-party languages and tools to develop your Oracle Database XE applications.InstallationInstallation of Oracle Database 10g Express Edition is extremely easy and can be done in less than 15 minutes. Oracle Database 10g Express Edition can be installed on both Linux and Windows platformsWhat to Do FirstIn this module, you learn how to log in to the Oracle Database 10g Express Edition browser-based user interface, create administration and database users.Users access Oracle Database 10g Express Edition through database user accounts. Some of these accounts are automatically created administrative accounts—accounts with database administration privileges. You log in with these accounts to create and manage other user accounts and to maintain database security.Creating a New Administration AccountThe installation process creates an account named SYSTEM. This account is considered an administrator account because it has DBA access.Using an Oracle best practice, try to create its own administrator account and password so that you can create database user accounts when needed!!!Steps:1. Log in as SYSTEM2. Select Administration>Database Users>Create User3. Input user information, check the DBA role for user and click CreateCreate your own administrator account!Creating a New Database User AccountYou can now log in with your administration account and create the necessary developer user accounts. Another user needs access to develop his portion of the application later, so you will create a new account for him!!!The same steps but don’t check the DBA role for user.Create a user account!Loading DataYou have an sql file manager that contains all the necessary commands and insert statements to load into the Oracle Database 10g Express Edition database.The script that will be loaded is called http://software.ucv.ro/~soimu_anca/DD/sample.sql This data contains information about each employee and about that employee's department.Steps:1. Log in with your account2. Select SQL>SQL Scripts> Upload3. Select the file you want to upload and click Upload4. Select the file icon and click Run twice to execute the script5. Review the results of the execution6. Browse the database objects and dataWorking with Database ObjectsOracle Database XE provides an organized mechanism for storing, managing, and retrieving information. Tables are the basic storage structure for holding business data. In this module, you learn how to create tables and work with them.You may want to modify data entered in tables. You may also want to maintain integrity with the data. Sometimes, you may want to remove tables that are no longer useful.•Creating tablesYou create tables with the SQL CREATE TABLE statement. With Oracle Database XE, you have two options for creating tables.•Use the graphical interface that generates the SQL statement•Enter the CREATE TABLE statement in the SQL Workshop toolWhen creating tables, you must provide:•Table name•Column name(s)•Data types for each columnGuidelines for creating tables:•Table and column naming rulesMust start with a letter, which is followed bya sequence of letters, numbers, _, #, or $Must be 1 to 30 characters longMust not be an Oracle server reservedpassword•Most common data typesVARCHAR2NUMBERDATETIMESTAMPCHARYou can also set up constraints on your columns to control the data in them.1. Creating Tables by Using the Object BrowserCreate the DEPENDENTS table, which will contain the following columns: Id, FirstName, LastName, BirthDate, Relation, Gender, Benefits, and RelativeId.In the DEPENDENTS table, no two rows have the same ID. The Gender column holds only one value of M or F. Also, the Benefits column stores large blocks of character data.Steps:1. Log in to Oracle Database XE2. Click the Object Browser3. Go to Create. Click the Table link4. Enter the table name and column definitions. Click Next5. Specify the primary key information. Click Next6. Specify the foreign key information. Click Add7. Proceed to check constraint information. Click Finish8. On the conformation page click Create2. Creating Tables Using SQLSheila needs to create the AUDIT_RECORD_TB1 table. This table will contain two columns. The user_value column is of the data type varchar2, and the date_recorded column is of the data type timestamp. Later, Sheila will use this table to record audit information when the salary column in the EMPLOYEES table changes.Steps:1. Navigate to Oracle Database>Home Page2. Click the SQL command3. Go to SQL Commands4. Click Enter Command5. Type the SQL command6. Click Run3.Creating a Copy of a TableTo copy the EMPLOYEES table so that she can practice without affecting the real data.Create a copy of the table by using the Object Browser.4. Modifying TablesYou can modify tables using the SQL ALTER TABLE statement. You may need to change the table structure due to any of the following reasons:•You omitted a column.•Your column definition needs to be changed.•You need to remove columns.The ALTER TABLE statement is used to:•Add a new column•Modify an existing column•Define a default value for the new column•Drop a column•Manage constraintsIn Oracle Database XE, you can modify tables:•Using the Object Browser•Using the SQL Workshop tool5. Adding a New ColumnAdd a new column BirthDate of Date type to the EMPLOYEES table by using the Object Browse.6. Managing ConstraintsWhat Are Constraints?Data integrity ensures the consistency and correctness of data stored in a database. Such integrity can be enforced by incorporating business rules. Constraints are the rules that are enforced on data stored in a table.Why Should I Use Constraints?You can use constraints to do the following:•Enforce rules on the data in a table whenever a row is updated, inserted, or deleted from that table •Prevent the deletion of a table if there are dependencies from other tablesTypes of Constraints:•PRIMARY KEYThe PRIMARY KEY constraint is a column ora set of columns that uniquely identifies eachrow in a table. This constraint enforcesuniqueness of the column or columncombination. It ensures that no column thatis part of the primary key can contain a nullvalue. A null value is a value that does notexist.For example, in the DEPENDENTS table, thecolumn ID is the primary key.This columnwill not allow either a duplicate value or anull value.•FOREIGN KEYThe FOREIGN KEY constraint designates acolumn or a combination of columns as aforeign key. It establishes a relationshipbetween a primary key or a unique key in thesame table or different table. A foreign keyenforces that the value within the columnmatches the value in the relationshipcolumn.For example, the RelativeId column inthe DEPENDENTS table refers to theEMPLOYEES table. You cannot delete arecord in the EMPLOYEES table whoseRelativeId is used in the DEPENDENTStable. Also, with a non-existing RelativeIdin the EMPLOYEES table, you cannot insert arecord into the DEPENDENTS table.•CHECKThe CHECK constraint enforces integrity byrestricting the values to be inserted in acolumn. It defines a condition that each rowmust sastisfy. You can define multiple checkconstraints on a single column. Also, youcan apply a single check constraint tomultiple columns.For example, when you impose the CHECKconstraint on the Gender column in theDEPENDENTS table, you can specify that theonly valid values are either M or F.•UNIQUEThe UNIQUE constraint requires that no tworows of a table can have duplicate values ina specified column or a set of columns. Atable can have more than one unique key. Ifthe UNIQUE constraint comprises more thanone column, then the group of columns iscalled a coomposite key.For example, you can impose the UNIQUEconstraint on the Email column of theEMPLOYEES table. You ensure that eachemployee has a unique email ID•NOT NULLConstraints can be enforced at two levels:•Column level•Table levelA constraint can be created with either of the following statements:•CREATE TABLE•ALTER TABLEWith the ALTER TABLE statement, you can disable or enable the imposed constraint without dropping it or re-creating it:•Disable a constraint by using the DISABLE clause.•Enable a constraint by using the ENABLE clause.1. Manage the constraints on the DEPENDENTS table by using the Object Browser:Steps:1. Navigate to Oracle Database XE>Home Page2. Click the Object Browser arrow3. Go to Browse4. Click the Table link5. Click the table name6. Click Constraints7. Click Create8. Specify the constraint information9. Click Next10. Click FinishCreate two constaints on table Dependents:1. Dependents_CON: the Gender column to take the values (‘M’, ‘F’) and2. Dependents_FK: the relativeid is the foreign key( reference Employees(Employee_ID))2.Disable the foreign key constraint on the DEPENDENTS table by using the appropriate SQL statement. Steps:1.Click the SQL arrow2.Go to SQL Commands3. Click Enter Command: SQL “Alter table dependents disable constraint dependents_fk”4.Type the SQL command5.Click Run•Accessing DataIn this module, you learn how to retrieve data from tables. The SQL SELECT statement is used to access and report data back from the XE tables. This is known as "querying" the data. In XE, you can either write SELECT statements using the SQL Workshop tool, or you can use the Query Builder tool to build queries with a GUI interface.1. Building Queries•Use the SQL Workshop tool to type her SELECT statements•Use the Query Builder tool to build the query graphicallyBibliografie:。
ORACLE 10G介绍
AWR采集与性能相关的统计数据，并从那些统计数 据中导出性能量度，以跟踪潜在的问题。与 Statspack 不同，快照由一个称为 MMON 的新的后台 进程及其从进程自动地每小时采集一次。为了节省空 间，采集的数据在 7 天后自动清除。快照频率和保 留时间都可以由用户修改。要查看当前的设置，您可 以使用下面的语句：
不是客户端安装的工具，实际上它是位于数据库服务 器上的一个 HTTP 服务器（称为 DB 控制台，参见下 图）。你可以使用任何浏览器查看 EM 界面。
DB 控制台使用的端口号可在 $ORACLE_HOME/install/portlist.ini 文件中找到。 以下是一个文件的示例(根据主机情况不一样，端口 可能不相同)
AWR 使用几个表来存储采集的统计数据，所有的 表都存储在SYSAUX 表空间中的SYS 模式下，并且以 WRM$_* 和 WRH$_* 的格式命名。前一种类型存储元 数据信息（如检查的数据库和采集的快照），后一种 类型保存实际采集的统计数据。
在这些表上构建了几种带前缀 DBA_HIST_的视图， 这些视图可以用来编写您自己的性能诊断工具。视图 的名称直接与表相关；例如，视图 DBA_HIST_SYSMETRIC_SUMMARY是在 WRH$_SYSMETRIC_SUMMARY表上构建的。 AWR 历史表采集的信息比 Statspack 多许多，这 些信息包括表空间使用率、文件系统使用率、甚至操 作系统统计数据。这些表的完整的列表可以通过以下 命令从数据字典中看到：
