事务控制的配置
Jboss事务处理也有相应配置：server/default/conf/jboss-service.xml
|
<mbean code="org.jboss.tm.TransactionManagerService" name="jboss：service=TransactionManager" xmbean-dd="resource：xmdesc/TransactionManagerService-xmbean.xml"> <attribute name="TransactionTimeout">300</attribute> <！—— set to false to disable transaction demarcation over IIOP ——> <attribute name="GlobalIdsEnabled">true</attribute> <depends optional-attribute-name="XidFactory">jboss：service=XidFactory</depends> <！—— Transaction Integrity Checking ——> <！—— Force a rollback if another thread is associated with the transaction at commit ——> <！——depends optional-attribute-name="TransactionIntegrityFactory" proxy-type="org.jboss.tm.integrity.TransactionIntegrityFactory"> <mbean code="org.jboss.tm.integrity.FailIncompleteTransaction" name="jboss：service=TransactionManager，plugin=TransactionIntegrity"/> </depends——> </mbean> |
如果要一台机器使用多个jboss server那么需要修改的文件server/default/conf/jboss-service.xml server/default/deploy/jbossweb-tomcat55.sar/server.xml
server/default/deploy/jbossweb-tomcat55.sar/server.xml配置要点
|
<Connector port="8080" address="${jboss.bind.address}" maxThreads="250" strategy="ms" maxHttpHeaderSize="8192" emptySessionPath="true" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="GBK"/> |
注：acceptCount是排队请求的数量；应该将线程数（最大线程数）设置比最大预期负载（同时并发的点击）多25%（经验规则）；应该将minSpareThread设置比正常负载多一些；
应该将maxSpareThread设置比峰值负载多一些；
minSpareThread指“启动以后，总是保持该数量的线程空闲等待”；
maxSpareThread指“如果超过了minSpareThread，然后总是保持该数量的线程空闲等待”
删除不需要的valve和日志；如果不使用JBoss的安全，删除JBoss的安全valve；预编译JSP（内置的编译器编译速度相当快，对于小的站点就没有必要预先编译了）
关闭sever/slim/jbossweb-tomcat50.sar/conf/web.xml中的development模式；URIEncoding="GBK" 基本解决了乱码问题
安全连接配置
