Hi: I am using portal rest api to add item. when the item type is file, I use the dataURL parameter. Like the sample below My question is when the dataUrl is English characters,it works fine, if the dataUrl has Chinese characters like this: http://myserver/csv/餐馆restaurants.csv. It failed. I try to encode the url ,it failed again. How can I do ? thanks

There is a very confused error in GeoEvent:javax.net.ssl.SSLException: Inbound closed before receiving peer's close_notify: possible truncation attack? It occurs when I update feature service I want to know why.

I have made a geoevent service to detect a car to enter a geofence and I have a alert featrue service that when the car inside the geofnce new featrue will update to .When the car is outside the geofence I want the featrue in alert would disapear after 1 minute, in fact it would be there all the time.I think I made the "Maximum Feature Age (Minutes):" ok.

Hello Chen - I'd like to make sure that I understand your question. Are you working with a single data stream and need advice on how to manually configure a cluster of GeoEvent Processor instances which will work collectively to pull and processing individual events from the high volume data being received? Support for high-availability and clustering are concepts being developed for the "11" product release which will feature a new type of stream service input. We are working to make this functionality available later this year. It may be possible to manually configure high-availability and clustering for the current 10.2.1 product release - but it depends on what exactly you are trying to accomplish. If you are working with several different (independent) data feeds, you can scale your site architecture by installing additional instances of GeoEvent Processor onto the GIS Servers in your ArcGIS for Server site. You would simply need to make sure that each instance of GeoEvent Processor had its own Inputs, Outputs, and GeoEvent Services. - RJ sorry,my english is just so so.you understand what i said. sorry again.currently users are not satisfied with the GeoEvent,because it not support for high-availability and clusters. i am from esriChina a agent of ArcGIS. i have some idea 1,when messges come from ,it will be Scratched in the kahaDB by the activeMQ. 2,if the size of kahaDB is bigger than a number that user specify in the com.esri.ges.messaging.jms.cfg ,then the activeMQ send the other messages to the slave machine. but master how to know the slave machine? in slave it can config a file that specify the master machine's IP and the kahaDB's shared file location. 3,ActiveMQ is using a network boker architecture thanks ,i am look forward to the "11" product.

hi: just one GeoEvent is too simple, i want to make a GeoEvent clusters. in the com.esri.ges.messaging.jms.cfg i see some things. com.esri.ges.messaging.jms.destinationPolicy.queue.memoryLimit=100 mb com.esri.ges.messaging.jms.destinationPolicy.topic.memoryLimit=100 mb com.esri.ges.messaging.jms.systemUsage.memoryUsage.limit=128 mb com.esri.ges.messaging.jms.systemUsage.storeUsage.limit=100 gb com.esri.ges.messaging.jms.systemUsage.tempUsage.limit=10 gb com.esri.ges.messaging.jms.brokerNamed=192.168.110.111 com.esri.ges.messaging.jms.dataDirectory=\\chenjun\data\activemq\localhost com.esri.ges.messaging.jms.kahadbDirectory=\\chenjun\data\activemq\localhost\kahadb com.esri.ges.messaging.jms.openwire.uri=tcp://localhost:61616 com.esri.ges.messaging.jms.stomp.uri=stomp://localhost:61613 brokerNamed is the master node? dataDirectory is the ActiveMQ Directory? kahadbDirectory is the kahadb Directory? i see some paper about the ActiveMQ,maybe the GeoEvent Architecture is Msater-Slave+Broker Cluster mode. is the geoEvent now support Cluster? if so, how can i modify the com.esri.ges.messaging.jms.cfg file?? i try to modify the file like this: in master i do nothing,but i shared a folder(C:\Program Files\ArcGIS\Server\GeoEventProcessor\data) in slave i modify the com.esri.ges.messaging.jms.cfg file com.esri.ges.messaging.jms.brokerNamed=192.168.110.111 com.esri.ges.messaging.jms.dataDirectory=\\chenjun\data\activemq\localhost com.esri.ges.messaging.jms.kahadbDirectory=\\chenjun\data\activemq\localhost\kahadb then, i send many messages to the master node. all messages is being Processed by the master machine, no messages is being blanced to the slave machine. i want this: when messages is too much, master and slave machine can process it together. one message only being processed once. like the arcgis web adaptor . so,how to do? thanks

Chen, Is HttpClient the external component you're trying to use? If so, GEP ships with HttpClient 4.2. To use the version that ships with GEP, add the following bock of XML to your pom.xml under /project/dependencies node: <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.2</version> </dependency> Rebuild your jar file using mvn and redeploy the jar file. That should allow you to use HttpClient. If you need a more recent version of HttpClient, then you'll need to drop all of the HttpClient jars and its dependencies into the product's deploy folder (C:/Program Files/ArcGIS/Server/GeoEventProcessor/deploy/). Let us know if this gets you any further along. -Javier thank you very much ,it work .

hi ,i want to use geoEvent sdk to create my outbound class, in the receive function . i write some code .but i must use a external .jar file. when i build the project ,i get a ****.jar file. i import it in the website(https://localhost:6143/geoevent/manager/components.html), then ,i restart it. i do not see my transport. in the log file(wrapper.log) ,i see the message. ERROR: Bundle sample.gep.sample-transport [341] Error starting file:/C:/Program%20Files/ArcGIS/Server/GeoEventProcessor/deploy/sample-transport-10.2.1.jar (org.osgi.framework.BundleException: Unresolved constraint in bundle sample.gep.sample-transport [341]: Unable to resolve 341.5: missing requirement [341.5] package; (package=org.apache.commons.httpclient)) it means the geoevent can't find the external jar file. how to do? some one says:put the external .jar file to the deploy folder , it not work. some one syas: modifythe pom.xml . can some one show me how to do?

Chen, Do you have a valid license installed? Check this by opening GEP_INSTALL_DIR\data\log\karaf.log and looking for a line the says "LicenseChecker." (GEP_INSTALL_DIR defaults to ARCGIS_SERVER_INSTALLDR\GeoEventProcessor. ARCGIS_SERVER_INSTALLDIR defaults to C:\Program Files\ArcGIS\Server. So for most installations, GEP_INSTALL_DIR= C:\Program Files\ArcGIS\Server\GeoEventProcessor) If you have a valid license, the line will say "License status: GeoEventProcessor: licenseStatusSuccess" If it doesn't say that, you'll need to install a valid license. You can do that by following steps 1-6 on this site. Let us know if this if this helps you out. -Javier yes, license is the problem.thanks
