ODM 8.11.1 | decisioncenter-api context root error running on samples server

  • 1.  ODM 8.11.1 | decisioncenter-api context root error running on samples server

    Posted Thu June 22, 2023 07:37 AM

    Hi All,

    I have installed ODM 8.11.1 in my local environment, onpremises installation. I can access all components except decisioncenter-api. The error is as follows:

    decisioncenter-api

    Translated: context root not found

    I have checked the server.xml file and it is correct. However, I have seen that in the plugin-cfg.xml file, all the components are mapped except decisioncenter-api:

       <UriGroup Name="default_host_odm81110_default_node_Cluster_URIs">
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/DecisionRunner/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/res/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/miniloan-server/*"/>
      <Uri AffinityCookie="JSESSIONID_DMN" AffinityURLIdentifier="jsessionid" Name="/decisionmodel/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/DecisionService/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/IBMJMXConnectorREST/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/ibm/api/*"/>
      <Uri AffinityCookie="JSESSIONID" AffinityURLIdentifier="jsessionid" Name="/decisioncenter/*"/>
   </UriGroup>

    How can I add the decisioncenter-api entry into plugin-cfg.xml file? If I do it manually, when I restart the samples server, it overwrites it.

    Thank you very much in advance

    Hi All,

    The reason for not adding the decisioncenter-api entry in the plugins-cfg.xml file, is related to the following Exception I found in the messages.log file:

    ------Start of DE processing------ = [22/06/23 12:42:33:719 CEST]

    If anyone has any suggestions, I would appreciate it.

    Thank you very much in advance.

    Hi All,

    I have decompiled the class that causes the error, com.ibm.rules.decisioncenter.DTFormat inside the teamserver-common-base-8.11.1.0.jar library and solved it by adding Locale.US in the date formatter pattern, like this:

    package com.ibm.rules.decisioncenter;


import java.time.format.DateTimeFormatter;
import java.util.Locale;

public interface DTFormat {
  public static final String DATEFORMAT_STR = "yyyy-MMM-dd";
  
  public static final String DATETIMEFORMAT_STR = "yyyy-MMM-dd HH:mm:ss z";
  
  public static final DateTimeFormatter DATEFORMAT = DateTimeFormatter.ofPattern("yyyy-MMM-dd", Locale.US);
  
  public static final DateTimeFormatter DATETIMEFORMAT = DateTimeFormatter.ofPattern("yyyy-MMM-dd HH:mm:ss z", Locale.US);
}

    Regards.
