Question

我正在使用apache activemq 5.8。这是我做的：

1）将informix jdbc jar（ifxjdbc-3.70-JC3.jar）放入activemq / libs / optional

2）在activemq.xml中声明bean：

 <bean id="informix-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.informix.jdbc.IfxDriver"/>
    <property name="url" value="jdbc:informix-sqli://192.168.7.30:21893/activemq_nightly:informixserver=ol_informix1170_1;IFX_LOCK_MODE_WAIT=20;IFX_ISOLATION_LEVEL=TRANSACTION_READ_UNCOMMITTED"/>
    <property name="username" value="XXXX" />
    <property name="password" value="XXXX" />
    <property name="maxActive" value="200" />
    <property name="poolPreparedStatements" value="true"/>
</bean>

3）更改activemq.xml中的持久性适配器：

    <persistenceAdapter>
    <jdbcPersistenceAdapter dataSource="#informix-ds"/>
    </persistenceAdapter>

我在informix连接字符串中设置了隔离级别，因为我得到了＆＃34;事务不受支持＆＃34;启动activemq时出错。现在我得到了这个例外：

2013-04-12 14:21:23,196 | ERROR | Failed to start Apache ActiveMQ (localhost, null). Reason: java.io.IOException: Cannot create PoolableConnectionFactory (Transaction not available.) | org.apache.activemq.broker.BrokerService | main

当我启动activemq时，我收到以下错误：

Answer 1

1）下载最新的activemq版本

2）vi ACTIVEMQ_HOME / conf / activemq.xml

3）添加以下bean配置以配置informix ds：

<bean id="informix-ds" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="com.informix.jdbc.IfxDriver"/>
<property name="jdbcUrl" value="jdbc:informix-sqli://192.168.7.30:21893/XXX:informixserver=ol_informix1170_1;IFX_LOCK_MODE_WAIT=20;IFX_ISOLATION_LEVEL=TRANSACTION_READ_UNCOMMITTED"/>
<property name="user" value="XXXXX" />
<property name="password" value="XXXX" />

注意：Informix连接字符串应包含：IFX_ISOLATION_LEVEL = TRANSACTION_READ_UNCOMMITTED。数据源实现应该是com.mchange.v2.c3p0.ComboPooledDataSource

4）将ds寄存为持久性适配器：

    <persistenceAdapter>

- ＆GT; 5）下载并复制c3p0-0.8.4.5.jar和ifxjdbc-3.70-JC3.jar到ACTIVEMQ_HOME / lib / optional

6）启动activemq并享受！

注意：如果activemq抱怨缺少db表，请检查数据库是否使用单字节字符集，或者手动创建具有适当约束的缺失表（仅适用于dev env）。

Answer 2

一个好的猜测是informix help

中描述的内容

-122 ISAM错误：交易不可用。

已要求ISAM处理器标记a的开头或结尾   事务，但事务日志记录不起作用。对于C-ISAM   程序，此文件未通过日志记录打开。查看电话   isopen，并确保包含ISTRANS参数。对于SQL   产品，此数据库不支持事务日志记录。如果你   正在使用数据库服务器，拥有数据库服务器管理员   启用此数据库的日志记录。否则，请使用START DATABASE   用于开始事务记录的语句。在所有情况下，应该记录日志   仅在数据库完全备份后立即启动。

如何配置activemq以使用informix数据库？
