DROOLS 5.6.0 Final Decision Table PermGen space OutOfMemoryError

by Jan Rose

Would like some advice regarding using Decision Tables in DROOLS 5.6.0 Final. We have decision tables with over 12,000 rows. It is a basic 'look-up' table with 3 conditions and 2 actions. The conditions are, for example: Company = X Dept = X Class = X then value = X and log X. When I reduced the number of rows to approx. 500 . .. it works. I have set the max memory in the JVM to 2 gigs. We have tried compiling the decision tables using the spreadsheet compiler as well as the decision table compiler. Below is the error when using the decision table compiler. However, we get the same PermGen space error with the spreadsheet compiler. Obviously, we need to be able to have more than 500 rows in our decision table(s). Any advice would be appreciated.

Drools 6.0.1: Pushing changes back to Workbench GIT using SSH

by dotrc

I am using workbench for managing my rules maven projects within the embedded GIT repository. I am aware that using git:// protocol, I can clone an existing rule repository; I can do this successfully. For authoring rules, I want to use Eclipse (using EGit). I want to push my commits back to the GIT repo. I understand that I'll have to use ssh protocol instead of git for specifying the repo, something like this: ssh://{userName}@localhost:8001/{repoName} When we use a standard GIT repo like stash, it gives us an option to set our public key on the stash server, but I'm not able to find a way to do that with the embedded ssh server within workbench. Hence, I'm not able to authenticate myself and perform a push. We tried creating a private-public key pair using ssh-keygen and put that within c:\users\<username>\.ssh and added the public key to 'authorized_keys(2) (though I know this may not be the right place) and then used the private key as the identity file with ssh client directly from cygwin, again to no avail. Any pointers will be really appreciated. Also, should the username be 'admin' or any other specific one for pushing? Will the existing Windows username work?

Re: [rules-users] Annotation @PropertyReactive not works

If I remember correctly this is a known issue. Unfortunately drools 5.6 is final and can't be patched. Downloading the source drl rather than the compiled pkg could be a workaround.

Sequential and Decision Tables

by sjrcgtek

Apologies if this is already answered but I could not find it. Drools Version 6.1.0.Final I have three Excel DTs which I would like to fire in order. The Sequential option appears to just order the rules within an excel DT. I confirmed that by printing the resulting rules and see that the generated rules from different sheets have the same priority. I can manually set the PRIORITY in the actual sheets, but that makes inserting sheets or even lines in a sheet cumbersome. Is there a way to tell drools to fire all rules across all DT's sequentially? Thanks. -- View this message in context: http://drools.46999.n3.nabble.com/Sequential-and-Decision-Tables-tp403063...

Creating simple Ruleflow via API and Spring

by mattmadhavan

Hello, My application is mostly rule driven and we do not have any states. We we are processing about 30 million facts in a stateless session using bunch of rules (DRL). I have a simple ruleflow requirement. I am looking for an example where I can create the rule flow via an API even better using spring. I have three condition checks and three Ruleflow groups. <http://drools.46999.n3.nabble.com/file/n4030634/ruleflow.png> Any help will be appreciated. Thanks in advance!
