At Nominet we have successfully migrated the remoting protocol governing communication between our client applications and the software running in the middleware layer. We have moved from SOAP to Hessian, refactoring the base code on the way. This post explains why we migrated, the advantages of th ...

***业务需要,先做个高级复制的(同步复制)。详细的说明如下：***
[Oracle] oracle高级复制同步复制配置步骤
首先，数据库要具备高级复制功能（用system身份登录数据库，查看v$option视图，如果其中Advanced replication为TRUE，则支持高级复制功能；否则不支持）
一.数据库基本情况
数据库A 版本oracle 10.2.0.1 数据库名sid:eread
数据库B 版本oracle 10.1.0.3 数据库名sid:test
主体定义站点:A eread主体站点:B test注:主体定义站点指配置复制工作的站点
本例涉及的 ...

Oracle高级复制即可支持基于整个表的复制也可支持基于部分表的复制两种复制方案。这两种复制方案主要是通过Oracle的两种复制机制来完成的，即多主复制和可更新快照复制，同时还可以将这两种复制机制结合起来以满足不断变 ...

死锁问题跟踪
当Oracle检测到死锁产生时，中断并回滚死锁相关语句的执行，报ORA-00060的错误并记录在数据库的日志文件alertSID.log中。同时在user_dump_dest下产生了一个跟踪文件，详细描述死锁的相关信息。
登陆到oracle安装主机上，cd /，执行find . -name alert*.log，此文件中有ORA-000060: Deadlock detected. More info in file /oracle/admin/vodapp/udump/vodapp_ora_7490.trc，view trc 文件找到相应的sql

H2提供了一种WebClient基于Browser的UI数据库客户端连接，可以连接多种数据库：H2, Oracle, HSQLDB, MySQL等，在Windows下可以通过以下两种命令方式：
方式一：
java -cp h2.jar org.h2.tools.Console
方式二：
java -cp h2.jar org.h2.tools.Server -tcp -tcpPort 9102（这种方式同时以tcp方式启动DB）
