Hi,

We are implementing a Decision Service by retrieving business rules at run time from ODM repository. Its done by using the Decision Service configurable service.

We have run the below set of mqsi commands to setup the configurable service:
Code:
mqsicreateconfigurableservice <<BROKER_NAME>> -c JDBCProviders -o ODMConfigSrc -n connectionUrlFormat
connectionUrlFormatAttr1
connectionUrlFormatAttr2
connectionUrlFormatAttr3
connectionUrlFormatAttr4
connectionUrlFormatAttr5
databaseName
databaseSchemaNames
databaseType
databaseVersion
description
environmentParms
jarsURL
jdbcProviderXASupport
maxConnectionPoolSize
portNumber
securityIdentity
serverName
type4DatasourceClassName
type4DriverClassName

-v
"jdbc:db2://[serverName]:[portNumber]/[databaseName]:user=[user];password=[password];"
""

ABCDB
ABC
"DB2 Universal Database"
10.1.0
default_Description
default_none
"C:\Program Files\IBM\SQLLIB\java"
true
0
50000
DB2SecurityIdentity
<<Remote_IP>>
com.ibm.db2.jcc.DB2XADataSource
com.ibm.db2.jcc.DB2Driver


Code:
mqsichangeproperties <<BROKER_NAME>> -c DecisionServiceRepository -o Default -n JDBCProviderName,resManagementHost,resManagementPort,resManagementProfiling  -v ODMConfigSrc,<<RES_Server_IP>>,<<RES_Server_Port>>,false


Code:
mqsisetdbparms <<BROKER_NAME>> -n jdbc::DB2SecurityIdentity -u <<user_name>> -p <<password>>


I have checked the "Use DecisionServiceRepository configurable service" in the Decision service node.

The error we get when trying to run this is,

Quote:

In the RES server info log, we see the below log,
Quote:
Info: Connection from "<<Broker_Server_Host_Name>>


The user trace gives below info,
Quote:
RecoverableException BIP4324E: The DecisionService node ''Decision Service'' in message flow ''ODM_Test_Sample'' cannot locate the ruleset ''tbtNrfbCheckrules'' in the remote repository that is defined by the DecisionServiceRepository configurable service.
The DecisionService node ''Decision Service'' in message flow ''ODM_Test_Sample'' (application ''Sample'', library '''') is configured to use a DecisionServiceRepository configurable service. The ruleset ''tbtNrfbCheckrules'' with namespace ''tbtnrfbCheclapptest'' cannot be located in the remote decision service repository as defined by the configurable service.
Check that the DecisionServiceRepository configurable service properties are correct. Check that the JDBCProviders configurable service properties are correct. Check that the ruleset ''tbtNrfbCheckrules'' with namespace ''tbtnrfbCheclapptest'' is deployed to the remote repository.


But the Decision Service is deployed and running in RES server. We are able to test that locally in ODM as well.


What could be the reason for this error? We tried searching this error and dont find any clue.[/img]

Are you sure that the ruleset is in the correct namespace?

And did you check the spelling for the rules asked for? (tbtnrfbCheclapptest)

Thanks for the inputs. We had the correct namespace and spelling specified. (The spelling of tbtnrfbCheclapptest was same at both Broker and ODM). But later we changed the name of namespace in ODM and reran the setup, things started working. Some strange reason!!

But now what we notice is another issue. As per documentation,
Quote:
By default, the hot deployment from business console will not reflect immediately to the execution group. You need to configure the Rule execution server for TCP/IP monitoring.

If you have not configured this, the rules will not reflect immediately. You need to restart the execution group to get the latest rules.


We have not configured the TCP/IP monitoring in RES server. Hence we are not seeing the changes made in RES reflect in Broker. The problem is, even with a EG or Broker restart we are not seeing the changes reflected in Broker.

So the doubt is how does this work and how to get the changes reflected in Broker from RES (without enabling the TCP?IP monitoring in RES)?
