配置 Gatein 為Oracle連接

主要環境：
      JBOSS 5.1.0

      Orace 10G

      Gatein3.1.0-GA

引用一下Gatein 官方使用手冊上的原文并簡單反譯和注解一下大概意思：-
 

2.1. Database Configuration
2.1.1. Overview
GateIn 3.1 has two different database dependencies. One is the identity service configuration, which depends on Hibernate. The other is Java content repository (JCR) service, which depends on JDBC API, and can integrate with any existing datasource implementation.

When you change the database configuration for the first time, GateIn will automatically generate the proper schema (assuming that the database user has the appropriate permissions).

GateIn 3.1 assumes the default encoding for your database is latin1. You may need to change this parameter for your database in order for GateIn 3.1 to work properly.

概述：     主要是說Gatein依賴兩個數據庫 一個是用來做身份認證的，是用Hibernate的。 另一個用來支持JCR的，用JDBC API 兩個都可以支持當前任何已存在的數庫。     在你第一次改變數據庫配置后，Gatein將會自動的生成schema（注解:數據庫的方案，就是表，視圖等）（你的數據庫用戶要有這些權限）    GateIn3.1假定你的數據庫編碼方式為latin1，你可能需要改變你的數據庫的編碼方式來讓Gate3.1正常工作 (注解：latin1 就是ISO8859-1編碼，這個好像是mySql常用的編碼方式，在我建立Oracle數據庫時并沒有這個編碼方式，我用的是UTF-8,這個是寬字符集，應該是兼容的，反正到現在還沒發現有問題)2.1.2. Configuring the database for JCR
To configure the database used by JCR you will need to edit the file:

$JBOSS_HOME/server/default/conf/gatein/configuration.propertiesFor Tomcat, the file is located at

$TOMCAT_HOME/gatein/conf/configuration.propertiesAnd edit the values of driver, url, username and password with the values for your JDBC connection (please, refer to your database JDBC driver documentation).

gatein.jcr.datasource.driver=org.hsqldb.jdbcDriver
gatein.jcr.datasource.url=jdbc:hsqldb:file:${gatein.db.data.dir}/data/jdbcjcr_${name}
gatein.jcr.datasource.username=sa
gatein.jcr.datasource.password=
By default, the name of the database is "jdbcjcr_${name}" - ${name} should be a part of the database name, as it is dynamically replaced by the name of the portal container extension (for instance, gatein-sample-portal.ear defines "sample-portal" as container name and the default portal defines "portal" as container name).

In the case of HSQL the databases are created automatically. For any other database you will need to create a database named jdbcjcr_portal (and "jdbcjcr_sample-portal" if you have gatein-sample-portal.ear in $JBOSS_HOME/server/default/deploy - note that some databases don't accept '-' in the database name, so you may have to remove $JBOSS_HOME/server/default/deploy/gatein-sample-portal.ear)

Make sure the user has rights to create tables on jdbcjcr_portal, and to update them as they will be automatically created during the first startup .

Also add your database's JDBC driver into the classpath - you can put it in $JBOSS_HOME/server/default/lib (or $TOMCAT_HOME/lib, if you are running on Tomcat)

MySQL example:

Let's configure our JCR to store data in MySQL. Let's pretend we have a user named "gateinuser" with a password "gateinpassword". We would create a database "mygateindb_portal" (remember that _portal is required), and assign our user the rights to create tables.

Then we need to add MySQL's JDBC driver to the classpath, and finally edit gatein.ear/02portal.war/WEB-INF/conf/jcr/jcr-configuration to contain the following:

gatein.jcr.datasource.driver=com.mysql.jdbc.Driver
gatein.jcr.datasource.url=jdbc:mysql://localhost:3306/mygateindb${container.name.suffix}
gatein.jcr.datasource.username=gateinuser
gatein.jcr.datasource.password=gateinpassword
2.1.2. JCR的數據庫配置修改配置文件： JBOSS: $JBOSS_HOME/server/default/conf/gatein/configuration.propertiesTomcat:$TOMCAT_HOME/gatein/conf/configuration.properties修改其中的驅動，url,用戶名，密碼，例如：gatein.jcr.datasource.driver=org.hsqldb.jdbcDriver
gatein.jcr.datasource.url=jdbc:hsqldb:file:${gatein.db.data.dir}/data/jdbcjcr_${name}
gatein.jcr.datasource.username=sa
gatein.jcr.datasource.password=

....略去說它自已的默認配置方式，重點在下一段里.....
說在數據庫為HSQL時，Gatein會自動的創建數據庫，但是如果是別的那么要手動的建立名為："jdbcjcr_portal"的數據庫
（注解：根據上一段所說，應該是庫名必須為_portal結尾，但是保險起見，我把我Oracle的全局數據庫名創建為，jdbcjcr_portal，
為這我還重裝了一次Oracle,不知道如果不改而只是創建一個名為jdbcjcr_portal的schema可以不可以，知道的試下告訴我一下吧）
（還要創建一個名為"jdbcjcr_sample-portal"的數據庫，為GateIn的一個例子使用，但是有些數據庫不支持"-"命名數據庫，
那么就把這個例子刪除，位置是$JBOSS_HOME/server/default/deploy/gatein-sample-portal.ear）
（注解：我是直接干掉了這個ear的，簡單方便）

要確保你的數據庫用戶有建表的權限。要把你的數據庫驅動考到$JBOSS_HOME/server/default/lib (你用Tomcat的話是$TOMCAT_HOME/lib)給出了一個mysql 的例子：gatein.jcr.datasource.driver=com.mysql.jdbc.Driver
gatein.jcr.datasource.url=jdbc:mysql://localhost:3306/mygateindb${container.name.suffix}
gatein.jcr.datasource.username=gateinuser
gatein.jcr.datasource.password=gateinpassword
我的
gatein.jcr.config.type=local
gatein.jcr.datasource.name=java:jdbcjcr
gatein.jcr.datasource.dialect=auto
gatein.jcr.datasource.driver=Oracle.jdbc.driver.OracleDriver
gatein.jcr.datasource.url=jdbc:Oracle:thin:@192.168.0.200:1521:dgoral
gatein.jcr.datasource.username=jdbcjcr_portal
gatein.jcr.datasource.password=XXXX
2.1.3. Configuring the database for the default identity store
By default, users are stored in a database. To change the database in which to store users, you will need to edit the file:

$JBOSS_HOME/server/default/conf/gatein/configuration.propertiesFor Tomcat, the file is located at

$TOMCAT_HOME/gatein/conf/configuration.propertiesYou will find the same kind of configuration as in jcr-configuration.xml:

gatein.idm.datasource.driver=org.hsqldb.jdbcDriver
gatein.idm.datasource.url=jdbc:hsqldb:file:${gatein.db.data.dir}/data/jdbcidm_${name}
gatein.idm.datasource.username=sa
gatein.idm.datasource.password2.1.3. 配置身份認證的數據庫還是上面的那個配置文件：JBOSS: $JBOSS_HOME/server/default/conf/gatein/configuration.propertiesTomcat:$TOMCAT_HOME/gatein/conf/configuration.properties例子：（注解：這個我和上面那個用的同一個庫，粘帖下就行了）gatein.idm.datasource.driver=org.hsqldb.jdbcDriver
gatein.idm.datasource.url=jdbc:hsqldb:file:${gatein.db.data.dir}/data/jdbcidm_${name}
gatein.idm.datasource.username=sa
gatein.idm.datasource.password
我的
# IDM
gatein.idm.datasource.name=java:jdbcidm
gatein.idm.datasource.driver=Oracle.jdbc.driver.OracleDriver
gatein.idm.datasource.url=jdbc:Oracle:thin:@192.168.0.200:1521:dgoral
gatein.idm.datasource.username=jdbcjcr_porta
gatein.idm.datasource.password=XXXX

看完上面的也就基本可以弄好了。多說一點，我對Oracle不是很了解，oracle的sid是不可以有“_“的，但是全局數據庫名可以有，但是連接url中的部分還是要寫sid的，寫數據庫名是不行了，有了解oracle的請指點一下。
