I am attempting to build an SDN app with OpenDaylight. I use the Carbon (latest) release and the OpenFlow plugin. I am trying to use the genius package as it has a lot of support for installing flows and such. I expect multiple switches to connect so I have to specify the "datapath ID" (dpid) in installing the flow. How do I determine the "dpid" when the switch connects?
Have look at line number 88 in this file, we extract DP id from node connector

I'm so confused I don't know how to perform mongo cdc with wso2 streaming integrator. I set up a mongo replicaset follow this doc. I config cdc source like below,
but it doesn't work, I got these error logs . Can any one help me to fix this? Thanks in advance.
It seems like an issue with the extension installer script of the WSO2 SI. The mongo_java_driver is actually a bundled jar and due to that it should not be converted again into a bundle.
So to fix your problem, Follow the below steps,
Step 1- Uninstall the installed MongoDB jar.
Step 2- Go to WSO2SI_HOME/wso2/server/resources/extensionsInstaller folder and open the extensionDependencies.json file.
Step 3- Search for "name": "mongo-java-driver" and under the configurations usage type from "JAR" to "BUNDLE".
Step 4- reinstall the MongoDB extension via extension installer
This will solve your problem.
Have you copy the mongo-java-driver to <PRODUCT_HOME>/lib directory? it seems like the cdc extension couldn't locate the mongodb drivers
Does anyone know how to use the make proxy command from the command line in order to see the documentations of the modules? I have installed Instant Veins 5.0 i2 with SimuLTE. It doesn't work generating from the IDE of OMNeT++, it returns an error and the cars simulation can't run, so i need to re-install the whole instant-veins-5.0-i2-simulte.ova file from scratch.
For "Veins LTE 1.3", module documentation can be generated by opening a terminal, changing to the veins/ directory (the one that contains sumo-launchd.py), and running make doxy. Module documentation is then available in doc/doxy/index.html.
Note, however, that Veins LTE has not been in active development for quite some time and integrating much more recent versions of SimuLTE and Veins is now possible via Veins_INET. For more details, see https://veins.car2x.org/documentation/modules/#lte
I am using SIFLess to install Sitecore 9.1 Update 1 on my local machine in order to get started with development with my team. However, the install is not creating certain databases on my system that are needed to get up and running, most notably the Reporting database. This of course causes problems when I deploy code from my team's repo to my local instance as it references these databases. I see that the SIFLess-generated PowerShell script has calls to a 'RemoveDatabase' function that references these databases in the uninstall method, but no code to create them in the first place during an install. The missing databases are:
MarketingAutomation
Messaging
Processing.Pools
ProcessingEngineStorage
ProcessingEngineTasks
ReferenceData
Reporting
Xdb.Collection.Shard0 and 1
Xdb.Collection.ShardMapManager
These are what I have gleaned from the uninstall logic in the PowerShell script generated by SIFLess. Again, no logic exists to create them in the first place in the install section. My team members all have these databases on their systems. What am I doing wrong? I am a Sitecore novice here.
Please make sure you are using the good package. You have to download the XP package, not XM. (Just to be sure here). Afterwards, the Database installation are done with DacPac found within the Sitecore Web Deploy Package ( *.scwdp).
Please, also make sure that within this scdwp you can see (can double click or extract) the database missing :
MarketingAutomation
Messaging
Processing.Pools
ProcessingEngineStorage
ProcessingEngineTasks
ReferenceData
And do the same with the xConnect SCWDP, and make sure you see the databse missing there :
Xdb.Collection.Shard0
Xdb.Collection.Shard1
Reporting
Sometimes, if you have tried the installation script more than once, you can have some undesired behavior. You are possibly trying to go forward with the wrong certificates. Also, some services were actually created on previous installation attempts.
Here is what I think should help you get through.
Clean your workspace
Remove your databases that are related to the installation if exists.
Remove your certificates (using certlm -> you can type in your windows search bar "cert" and then you should be able to pick "Manage computer Certificate".
On the left sidebar, Click on Personal > Certificates.
Remove your installation-related certificates
nameOfYourInstallation.identityserver
nameOfYourInstallation.sc
nameOfYourInstallation.xconnect
Open your Windows Services Manager (you can type in your windows search bar "services" and select the services app)
You should be able to see those services :
Sitecore Marketing Automation Engine - nameOfYourInstallation(might be one of your previous install)
Sitecore Processing Engine - nameOfYourInstallation
Sitecore XConnect Search Indexer - nameOfYourInstallation.
Write those down. Keep your service app open.
Using NSSM (probably installed already from some of your previous installed, if not, can use chocolatey ( https://chocolatey.org/packages/NSSM ) remove those services.
in a cmd : nssm remove serviceName
Note that you can remove them by right clicking etc. I just prefer the nssm way.
When its done, restart your computer (some services and in a state of removal, that needs a restart to be completely removed)
Try to install again.
Hope it helps, cheers !
Getting the following error when using drone cli to add/activate repo
No help topic for 'add'
I can confirm I am successfully login and I am an admin.
{"id":1,"login":"XXXXX","email":"","machine":false,"admin":true,"active":true,"avatar":"https://bitbucket.org/account/XXXX/avatar/32/","syncing":false,"synced":1578888217,"created":1578431775,"updated":1578891320,"last_login":1578891344}
I can also list my repo using 'drone repo ls'
My guess, if you are using the add option is that you are still interacting with drone 0.8 or below, in this case the docs have been archived to an alternate location in favor of the latest version (v1.x). The old docs are still available under the following URL and help for the add option is present there:
https://0-8-0.docs.drone.io/cli-repository-add/
If you are not using 0.8 and are indeed trying to use 1.x, perhaps you are referencing improper documentation, as this cli option shifted in v1 to enable
$ drone repo enable <repo/name>
Regardless of the versions however, you will want to ensure you both have admin access to the repository (so that drone is able to add the appropriate webhooks) and also refresh or sync your repo listing in if it is something brand new:
$ drone repo sync
username/hello-world
organization/minio
...
NOTE: This might take a bit depending on how many repos you have access to
I am using TcServer Release 3.1.0 on a Windows Environment, specifically the "cluster-node" template, the problem consist that when I run the command to create the server it's based on tomcat-7, and I need it to be based on tomcat-8, here is the command that I am using it:
tcruntime-instance.bat create myserver1 --template cluster-node
and here is the message that i get from the command prompt:
Applying template 'base-tomcat-7'
Reading on the documentation it says that depends on the tc Runtime version to select between "base-tomcat-7" or "base-tomcat-8" to be used by the instance, so any ideas to make mandatory apply the base-tomcat-8?
Thanks in advance.
That tc Server version defaults to tc Runtime 7. You need to pass in the --version parameter specifying the 8.0.XX version along with the templates you want.
