Re: [rules-users] Workbench and GIT Repo High Availability
Hello Zahid, Comments inline... On May 13, 2014, at 3:56 AM, Zahid Ahmed zahid.ah...@emirates.com wrote: Hi, We are in a process of setting up a centralized drools6 Workbench in our organization. This way we can keep our assets and artefacts in a central location. We will make this central Workbench clustered for high availability. I have a few queries in regard to clustering the Workbench. Problem Statement As workbench is using GIT, this means we need to have an enterprise level GIT repository where all the assets get stored for Workbench. As GIT is file-system based , it in turn, calls for a clustered GIT server within the organization. Our organization will prefer to have a private GIT repository hosted within office network which is highly available and wants to avoid any cost for GIT repository setup. Workbench doesn't force you to have any extra cost with GIT, as it comes with it and you don't need an external (outside your network) provider as Workbench has it's own GIT infra. 1. I want to know how to make Workbench highly available , with GIT also Highly available. Is chapter# 18 VFS CLUSTERING is the answer to high available GIT and WORKBENCH both ? or is there any other way to make GIT repository highly available. The Workbench cluster is a Highly Available type of cluster, all you need is follow the instructions and you'll have what you need. To be even more clear: as GIT is embedded in Workbench solution, once you setup a Workbench cluster you get for free a GIT HA setup. But if you're looking for a proxy based solution (Workbench accessing your own external GIT cluster using whatever solution you have) - this we don't support, Workbench will always have it's own GIT infra embedded. 2. Will ZooKeeper and Helix be enough to make the clustered environment for both Workbench with its GIT repo ? Yes... ZK and Helix does the job! Be aware that you'd need to have a proper ZK setup (another cluster) in order to obtain a real HA cluster. Your final solution will be probably end up with 3 ZKs in a cluster + the Workbench cluster (both clusters can be setup in the same nodes if you want).

[rules-users] Startup KIE Workbench without network connection

For example, using jboss, I have in standalone.conf file (used during jboss startup) JAVA_OPTS=$JAVA_OPTS -Dorg.kie.demo=false -Dorg.kie.example=false This will disable the demo and the example sources from the workbench.

Re: [rules-users] Startup KIE Workbench without network connection
Hello, many thanks for that information! I somehow never got that far down in the properties-page to notice. Nevertheless I think that the startup should not fail completely, if the sample repositories cannot be downloaded. Shouldn’t a warning suffice? Thank you!

Re: [rules-users] Rules don't execute using MVEL syntax in RHS - Possible Bug
Hi Josep, as I anticipated the propName vs. getPropName() issue was only a red herring and totally unrelated with the actual bug. Investigating in more detail your test case I found that the problem is that in some circumstances, when using fireUntilHalt, a single working memory action (insert/update/delete) is not processed atomically as it should. This causes that it can make to fire a rule even before than the consequences of such action have been completely propagated to all the nodes of the rete network. Yesterday evening I finished developing a fix for this issue that also makes your test case to pass. However I only pushed it on a branch of my personal guthub repo ( https://github.com/mariofusco/drools/commit/6d7a849f0920e95c22aa913f0cc5b741b1ddb92b ) because there are still some outstanding details that I am discussing with the other members of the team. I'll let you know when we decide that the fix is ok and merge it to the master.
