	开发服务器数据清理

English

In development server, due to the fact that process design will always get updated and developed, there will be more and more XPDLs cached in the memory. In the long run, this may cause "java.lang.OutOfMemoryError" exception during runtime or server startup. To solve this issue, we will need to clean up the unused XPDLs with following steps. The following example queries are written in MySQL and MSSQL syntax.

Chinese
在开发服务器中，由于进程设计总是会得到更新和开发的，所以内存中会有越来越多的XPDL缓存。从长远来看，这可能会在运行时或服务器启动时导致“ java.lang.OutOfMemoryError ”异常。要解决这个问题，我们需要按照以下步骤清理未使用的XPDL。以下示例查询是使用MySQL和MSSQL语法编写的。
