A: 1. Check whether the network analysis service url is correct. 2. Check whether the distance tolerance for publishing network analysis service is changed as required. 3. Check whether the network dataset for network analysis service has the data errors.
04 Jul,2019 iserverA: Because it sets the read-only permission when the workspace opens the datasource. You can cancel the datasource read-only permission. Or you can set the overlay analysis parameter dataReturnOption to RECORDSET_ONLY, and return the recordset.
04 Jul,2019 iserverA: Yes. You can open the cluster service in the host node, and set the token value (such as: supermap). The host node changes controllable node in the SuperMap iServer installation directory\webapps\iserver\WEB-INF\iserver-system.xml. Input the host node service address informations and so on. Then restart the child node iServer.
04 Jul,2019 iserverA: SuperMap iServer will write the temporary file in the operating system directory (such as the %Temp% in Windows and /tmp in Linux) When using the database workspace. If there is not enough space in the temporary directory, the database workspace can't connect. So when you use the database workspace, you should make sure that the system temporary directory has the enough space.
04 Jul,2019 iserverA: SuperMap iServer supports to adjust the database checking frequency, namely, check the internal whether the "database workspace" is changed or "database datasource" is disconnected. The detailed method is: you modify the parameter in the system configuration file (iserver-system.xml).
04 Jul,2019 iserverA: Please check the map data of child nodes. If you use the file datasource, please ensure that the map data of child nodes have the same path with the parent node data.
04 Jul,2019 iserverA: Export the MBTiles file when the FastDFS map tile set is being written and the result may not contain the latest tile result. If the map tile set is the first time to be written, the exported MBTiles may appear blank; If it is not the first time, the exported MBTiles file will not contain the latest results, resulting in the incorrect tiles. So please export the MBTiles file after the FastDFS map tiles are written.
04 Jul,2019 iserverA: when you deploy iServer services, you can not use the parentheses in JDK/JRE path; otherwise, the Oracle datasource connection will fail.
04 Jul,2019 iserverA: It may be caused by the lack of relevant dynamic library files. Now the known files are: libgomp-4.4.0-6.el5.i386.rpm and libgomp-4.4.0-6.el5.x86_64.rpm.
04 Jul,2019 iserverA: Please configure the IP address corresponding to host name in /etc/hosts file. If you add the last row, it means to map linux to 192.168.1.101. # Syntax: # IP-Address Full-Qualified-Hostname Short-Hostname 127.0.0.1 localhost 192.168.1.101 linux
04 Jul,2019 iserverA: As to certain services, the memory is not enough. To solve the problem, use 64-bit iServer, or modify the Java virtual machine memory in catalina.sh/bat in bin directory, and add "-Xmx1024" to JAVA_OPTS, then restart SuperMap iServer.
04 Jul,2019 iserverA: When you want to stop iServer, please use shutdown.bat/sh, not Ctrl+C.
04 Jul,2019 iserverA: The 64-bit SuperMap iServer needs the 64-bit Oracle client. Make sure your current Oracle client is 64-bit.
04 Jul,2019 iserverA: For style of point symbol, you need to set the lineColor property.
04 Jul,2019 iserverA: In this case, the cache of two maps would be stored in the same cache directory, and may cause cache mess. It is prefer to use different map names.
04 Jul,2019 iserverA: Make settings according to the real situation: (1) If you plan to use map services, do uniform settings for SuperMap iObject Java 7C on every GIS server in the cluster. Open the file SuperMap iObjects Java 7C\Bin\Supermap.xml, and set CustomMapRatioEnable as true (true). Otherwise, the map may not be able to properly displayed. Note: SuperMap iObjects Java in SuperMap iServer has already changed. (2) SuperMap iServer is deployed in the Servlet container in the form of Servlet. If the SuperMap iServer, which is a child node of the cluster, is moved to another Servlet container with a different port, you need to manually change the port under node in the iserver-system.xml file to a new one. In addition, you can access any GIS service on the child node to automatically set a new port. (3) The special character“^” can't be used in the server URI.
04 Jul,2019 iserverA: The 64-bit Linux operating system is missing 32bit support library, and need to install 32-bit support library. You can insert the system disk to install related libraries, or you can obtain the libraries from the official website of the operating system.
04 Jul,2019 iserverA: You can use the HTTP request header to carry the HTTP Form authentication, with the Cookie information generated at login. E.g. Open Chrome or Firefox, get the Cookie value when successful login, then bring the Cookie in the request to be build.
04 Jul,2019 iserverA: You can set DatasetOverlayAnalystParameters.resultSetting to the return dataset name.
04 Jul,2019 iserverA: Yes, it is required to purchase license for 3D Spatial Analysis Service and 3D Network Analysis Service.
