| 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. |
