Additional defects details

This section lists additional information for select defects.

16046477 – New Inline Service CrossSellR, sample integration with ORE

A new sample inline service is included in 3.0.0.1.12 PSU to demonstrate using external R models in Oracle RTD. You will find the inline service in OracleBI\RTD\examples\CrossSellR and documentation for it in OracleBI\RTD\docs\ORE Integration.pdf.

14461859 – XML Response from advisor invalid with special characters

Special chars (like & or <) are not properly escaped in the response from an advisor (for  example  "&" is not transformed to "&amp;"). This regression was first introduced in 3.0.0.1.10 PSU and is fixed in 3.0.0.1.12 PSU. If you implemented a workaround of escaping the response in the inline service, you should remove this workaround as part of your 3.0.0.1.12 PSU.

14300740 – New API to remove external rules from the server cache

External rules are cached in the server. The cache is cleared if the inline service is  undeployed. If you want to remove a specific rule from the server cache without  undeploying  the whole inline service you can use the new ‘remove(RuleDefinition  def)’ method in theRuleCache  interface. This method is used in the Base Marketing RTD Application Inline  Service,  refer to this for an example on how to use this new method.

14169133 - Performance improvements in the external rules compilation code with the addition of a new batch compilation API

 If your Inline Service(s) has a lot of external rules, you can use new APIs to compile rules in batch in order to improve the initial load time of these external rules by using the new ‘validateAndCache(@NonNull  List<RuleDefinitionContextPair>  ruleDefContextList,RuleCache  cache)’ method in the  RuleEvaluator  interface. This method is used in the Base Marketing RTD Application Inline  Service,refer to this for an example on how to use this new method.

11668572  JBoss – Request forwarding channel reset error fix using Jgroups 2.8.
10031983  Weblogic/Websphere - Request forwarding channel reset error fix using Jgroups 2.8.

The resolution of these two defects affects the RTD installation process, especially for cluster setups.  See the Applying This Patch in this document for details.

10411524  RTD decision service java client to support JUL logging, automatically generate session key in header, support user-defined header.

The 3.0.0.1.10 PSU and later RTD decision service client (rtd-ds-client.jar) supports the following:

1. A new RTDSESSIONKEY http header is automatically generated for IP requests which include session key/keys. The value is hex(hash(first session key)), which follows RegEx pattern [0-9, a-f]{8}.

2. A new method void setHttpHeader(String name, String value); has been added to IntegrationPointRequestInterface for users to set arbitrary http headers.  

3. Logging has been changed to Java Utility Logging (JUL).  Log4j is not used or required.  Configuration can be done in java source code as follows:
 
java.util.logging.Logger rtdLogger = java.util.logging.Logger.getLogger("oracle.rtd.logger");
rtdLogger.setLevel(java.util.logging.Level.WARNING);
rtdLogger.addHandler(new java.util.logging.FileHandler("rtd.log"));

10390665  Add system property to bypass ILS test loading during ILS deployment

A new system property, rtd.skipIlsTestLoad, has been added to bypass test loading of an Inline Service during ILS deployment.  If unspecified in the JVM start parameters, the property has a default value of false, which means ILS test loading will be performed during ILS deployment.  If the logging level is set to DEBUG, the following message can be seen in the server.log:

2011-04-10 11:04:10,142 DEBUG [DeployAppCommand] Performing test load on CrossSell with deployment state 5.

Set the property to true, e.g. -Drtd.skipIlsTestLoad=true to bypass ILS test loading. This may be helpful in ILS redeployments from Decision Center in a clustered environment.

10387803  Decision Service performance log (ds_perf.csv) - additional request forwarding metrics
9096379   Decision Service performance counters - add request forwarding metrics.

The following metrics have been added to the Decision Service mbeans (OracleRTD > Server > DecisionService) and Decision Service performance log:

1. Requests Forwarded, Peak

2. Requests Forwarded, Total

3. Received Requests Forwarded, Current

4. Received Requests Forwarded, Peak

5. Received Requests Forwarded, Total

10383794  Decision Center - increased precision shown in report data.

Decision Center reports where percentages are shown now display at least one decimal place instead of rounding to nearest integer.

10178734  External Rule Editor - add option to hide inherited rules.  [For Decision Manager].
9959417   External Rule Editor - add option to override default title value.  [For Decision Manager].
9726419   External Rule Editor - add option to display rule editor in read-only mode.  [For Decision Manager].

The new external rule editor rendering optional properties can be set as follows:

<input type=hidden name="hideInheritedRules" value="true"/>

<input type=hidden name="title" value="My title"/>

<input type=hidden name="readOnly" value="true"/>
