04 Jul,2019 iserverA: IServer connecting to the kingbase databse is the same as oracle. It needs to be installed the package with same bit of iServer.
04 Jul,2019 iserverA: 1. Unzip the iServer.war, and find WEB-INF 2. Open the web.xml in the WEB-INF folder 3. Change the web-app_3_0.xsd to web-app_2_5.xsd and version=3.0 to version=2.5 4. Delete the true
04 Jul,2019 iserverA: wfs service returns 2000 features by default. You can set wfs1.0.0 or 2.0.0 to 0 or -1 in iserver-services-interfaces.xml of SuperMap iServer installation directory\webapps\iserver\WEB-INF, which means to return all features.
04 Jul,2019 iserverA: wfs1.0.0 doesn’t, but 2.0.0 does. “SORTBY” parameter is used to specify the properties sort. It can be ASC or DESC. If there is no sort, the ASC is default. For example, “SORTBY=Field1 DESC,Field2 DESC,Field3” means Field1 and Field2 are sorted by DESC, and Field3 is sorted by ASC
04 Jul,2019 iserverA: 1. After you publish the workspace containing the file datasource and configure to multiple instance, the datasource is opened read-only. It will not support to change. But the database datasource still supports to change. 2. If it is not enabled multiple instances when you publish the workspace, and you open and configure multiple instances in the service manager, the configuration is valid only when the service provider uses a GIS service type, such as for publishing the map services. 3. If the number of service instances is larger than the number of workers, the service instance is deployed in each Worker by default. When the number of workers is increased, the service instance is deployed automatically according to the configuration.
04 Jul,2019 iserverA: 1. Map tiles have following formats: The map tiles which cut all map layers and saved as grid images. It supports FastDFS, MongoDB, OTS distributed storage, SMTiles, MBTiles, SuperMap UGC, and GeoPackage. 2. Vector tiles Cut and store the specified vector layers in map as vector tiles. It supports SVTiles. 3. Attribute tiles Store the attribute data of the vector layers in map as attribute tiles. It supports UTFGrid.
04 Jul,2019 iserverA: 1. Update and append tiles manually. You only need to select the location of the tile file (such as output path \sqlite\) or the tile library (determined by the storage ID) when selecting the storage location. Of course, you will also need to select the additional scale and map range, which will update the existing tiles automatically if it repeats. 2. Use the tile tool to update Login service manager, and click "Service", "Advanced" and "Tile Update" in turn, and you can start to use the tile update tool. 1) Click “Create a tile updating task” to enter the task creation page 2) Set “Input tile set”, namely, update the tile data source 3) Set the target dataset”, that is the tile package to be updated or changed 4) In the "Input tile set scale" list, select the scale that needs to be updated and click the "Add" button. 5) Set the updating scope. The default is the maximum range of tiles. 6) Click the “Start” button
04 Jul,2019 iserverA: Possible reasons are in the thematic map setting. Please pay attention to the description of the class references. For example, the statistic thematic map height and width unit is consistent with the map unit; latitude and longitude unit is in degrees; the projected coordinates is in meters; no projection is the other; If it is a projected coordinate map, but the icon height and width is configured according to the longitude and latitude map, then the icon will not be displayed because the size us is too small.
04 Jul,2019 iserverA: Find wmts100 in “Service Manager-Service Interface” of iServer. And remove the scale.
04 Jul,2019 iserverA: No, you can’t. But you can use the tile updating to achieve indirectly. The tile updating URI: http://{IP/domain name}:{port}/iserver/manager/tilesetupdatejobs But first you need to have a same map tile set in MongoDB. It can make the first grade scale tiles to MongoDB. Then update the smtiles tiles to the tiles in MongoDB.
04 Jul,2019 iserverA: Please find the provider you want to modify in iserver directory/webapps/web-inf/iserver-services.xml, and set the nodes of map services or data services.
04 Jul,2019 iserverA: When you tile local caches, please note that set the scope to local, but the coordinates origin should be in full scope.
04 Jul,2019 iserverA: From the following two aspects: 1. Check whether mysql maximum number of connections has reached the upper limit. 2. The mysql database will disconnects after a certain amount of time.
04 Jul,2019 iserverA: Send the http request through the rest API, and the request example is as follows: http://supermapiserver:8090/iserver/services/map-world/rest/maps/WorldMap/layers/Capitals@World@@ WorldMap/style.rjson Please refer to the Help document > REST API > services > root > maps > map > layers > layer > style. You can view the detailed request methods and parameters.
04 Jul,2019 iserverA: If you set the source accessibility to “copy this application to each target" or set the planned source accessibility to "copy this plan to each target" in weblogic when you deploy iServer, it will repeat deployment steps when the weblogic starts, and iServer will be reset. So please set above two places as default when you deploy them.
04 Jul,2019 iserverA: Because the libmawt.so used in component is different from the libmawt.so used in the JREHOME/lib/amd64/headless file. You can replace the libmawt.so in UGO_HOME/bin to the one in $JRE_HOME/lib/amd64/headless/libmawt.so.
04 Jul,2019 iserverA: You need to refer to iserver-all-{version}.jar and its dependencies. It is recommended that all packages are referenced before the development is completed. Then remove them after the development is completed. In general, we only use JAVA API to dock part of iServer functionalities, such as iServer map services, data services and so on. The following packages are needed (version depends on the circumstances): aliyun-sdk-oss-2.0.6.jar cal10n-api-0.7.7.jar commons-io-2.5.jar commons-lang-2.6.jar commons-lang3-3.5.jar ehcache-2.10.3.jar fastjson-1.2.8.jar iserver-all-8.1.1-14511.jar jsr311-api-1.1.1.jar log4j-1.2.17.jar org.restlet.ext.json-2.2.3.jar org.restlet.lib.org.json-2.0.jar org.restlet-2.2.3.jar rest-sdk-8.1.1-14511.jar service-model-8.1.1-14511.jar slf4j-api-1.7.21.jar slf4j-ext-1.7.21.jar slf4j-log4j12-1.7.21.jar
04 Jul,2019 iserverA: For example: Migrate the cache tiles in mongodb server1 (D:\mongodb1) to mongodb server2 (D:\mongodb2); 1. Start the server1 (the port is 27010); mongod.exe -dbpath D:\mongodb1\data\db -port 27010 2. Then open a cmd window, and switch to the bin directory of server1. Export the smtiles data in server1 to BSON files; mongodump.exe -host localhost -port 27010 -d smtiles -o D:\output the “smtiles” is the specified database name. The default database name of iserver distributed tiles is smtiles “D:\output” the specified exported directory. 3. View the exported files. Copy the data files to the server2 that can be accessed or has permission. 4. Start the server2 (the port is 27015); mongod.exe -dbpath D:\mongodb2\data\db -port 27015 5. Import the BSON corresponding to above smtiles database to server2 mongorestore.exe -host localhost -port 27015 -d smtiles D:\output\smtiles “smtiles” the specified database name “D:\output\smtiles” the location of the storage file.
04 Jul,2019 iserverA: Because in the Linux platform, when you use Oracle Client to connect Oracle Server to open the database, UGO lacks the dependency file libclntsh. So.10.1. The specific solution is as follows: (1) Build soft connection. Enter the %ORCL_HOME%/lib directory, and establish the file libclntsh.so.[version number] to a soft connection named libclntsh.so.10.1, that is, run the command In –s libclntsh.so.[version] libclntsh.so.10.1. (2) Verify whether the UGO dependencies are correct. Execute the ldd –d libSuEngineOracle.so in the UGO directory. Then you can view the output information, if there is no "not found", it means the UGO dependencies are correct. After restart SuperMap iServer services, the workspace services containing Oracle datasource can be accessed normally.
