Tags: Oracle performance databaseWhen Oracle queries come with efficiency issues, we often need to understand the problem so that we can solve the problem. Oracle provides trace information for SQL execution, which contains textual information about SQL statements, some execution statistics, waiting during processing, and information generated by the parsing phase, such as generating execution plans. This information helps you to diagnose performance problems by breaking down the service time an

BackgroundBecause the project needs to be used in the Java Web project to map, manufacturers provide a DWG format of the map, and we are using Mapxtreme Java technology, so we should first convert the DWG format map to Mapxtreme Java can parse the format, that is, the GST format. On this aspect of information, very few online, coupled with software difficult to find, the middle of a lot of detours. The process of DWG to GST is also necessary to be possible after Mapxtreme Java, so it's time to s
