Re: [rules-users] DROOLS 5.6.0 Final Decision Table PermGen space OutOfMemoryError
by Jan Rose
Mark, thanks for responding. Do you have a recommendation as to how much I should
increase the perm gen space?
Also, is there anything else I can do to run my decision tables more efficiently?
Jan
try increasing your perm gen space.

Kie-Spring Issue, not able to created Session as "prototype"
by mattmadhavan
Hello,
I have the following kie-spring xml definition to test my custom evaluater.
Please note the * type="stateless" scope="prototype"* in the xml
configuration. Everytime this session is looked up, I want a new instance of
the StatelessKieSession.
I am getting the same instance for both the look ups! Looks like the session
bean is created as a Singleton even though I specified prototype scope.
I really need to create prototype version of my StetelessKieSession on
demand ( I am using Camel routes) as I increase the number of JMS clients to
process the load. This is a critical feature I really require.
Any ideas please? Seems to that kie-spring is not really mature enough!
Thanks in advance!
Matt'M

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?
Thanks,
Rishi

Re: [rules-users] Annotation @PropertyReactive not works
by Davide Sottara
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.
Please let me know if it works

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.
