Custom Installation of Talend Runtime
and Talend JobServer
on the same server might cause port conflicts If you install Talend Runtime and Talend JobServer as Service on the same machine, you need to make sure that you change the port of the standalone Talend JobServer. Otherwise these ports will be in conflict with the Talend JobServer included in Talend Runtime, which uses the same default ports as the standalone Talend JobServer. |
As a workaround, consider first if you really need the standalone Talend JobServer, the Talend Runtime (which also includes a Talend JobServer, for DI use only), or if you need both on the same machine. Only in the last case you should make sure that you use other port during the setup for the standalone Talend JobServer (a configuration page is shown during installation). |

Java PSU not supported |
Talend is only supported on Java CPU Versions, not Java
PSU. Some users reported problems using Talend Studio with Java PSU versions (such as jdk8_u92), but when reverting to a Java CPU Version (such as jdk8_u91) the problem was resolved. See also: this documentation. |

Only WS-I Basic Profile compliant WSDL documents are supported | All WSDL service descriptions should be at least WS-I Basic Profile compliant if you want to use them in Talend Studio. See http://ws-i.org/deliverables/basicprofile.html. Other WSDL documents might also work but they are more likely to fail. |

The Activity Monitoring Console as provided in the Studio and the related Dashboard screens can be used to visualize tLogCatcher, tStatCatcher and tFlowMeterCatcher events. In Talend Enterprise ESB there are some limitations that you need to consider for these components and the related features in the Studio. |

tWaitForXXX components are not supported in Talend ESB Data Services and tRoute Jobs | The tWaitForFile, tWaitForSqlData and tWaitForSocket components are not supported to be used in ESB Data Services (REST&SOAP) or in tRouteInput based Jobs (cTalendJob use cases). |

tRunJob is supported with limitations | The tRunJob component is supported with limitations,
which means that only S4 (Minor) support cases are accepted and no patches
are provided. If you use tRunJob within Data Services and Routes (with
cTalendJob), support is provided on a "best effort" basis only. In most
cases, there are class loading issues which can sometimes be resolved but
not always. This is because tRunJob is not designed to work in a Service/Route style (ESB) deployment, so regular support is not provided if you decide to use it, even though it may work in many cases. If you used tRunJob in the past, it is recommended to change your Job Design to use Joblets instead. For DI and non-ESB use cases, it is still a valuable component and will have full support as before. Additionally, the Use dynamic job option is not supported within ESB Routes or Data Services at all. |

tParallelize does not work with Data Services Jobs and Routes | The tParallelize component is designed for Data Integration Jobs. Do not use it in the context of Data Services Jobs and Routes because it is not thread safe between parallel requests and will cause huge memory and CPU consumption. Use a Route if parallel processing is a requirement. |

Route Builder beans cannot be organized in packages
Beans in a route build can be used to add Java code for the route builder routes, however all beans are currently located in one single package. |

XML payload content is not fully displayed in trace or
debug mode When starting a Data Service Job in trace/debug mode, the content of the Document fields of the flows is not displayed fully - only the first line of the XML payload is shown. |
If you need to see the XML data you can place a tLogRow component anywhere in your models. Keep in mind that Talend Studio also allows you to disable this component, so that you can enable it for testing inside Talend Studio, but disable it for export or publishing. |

Modifications to components in the source Route are not
propagated to test cases
When you change the configuration of a component in a Route, the changes are not propagated to the related Route test cases automatically. |
You can close the test case and reopen it to get the changes in the components propagated in the test case. |

Filter can be applied with the CI for ESB to limit the Data Services and Routes which get built and deployed by the CI Builder maven plugin. Nevertheless when a Route uses cTalendJob, it will only work in case the Job and the Route are both part of the filter (criteria). |
A recommendation would be to name the Job(s) with the same name as the Route with any extra details after the Route name. By this, the Route and the Job(s) would have the same starting name and would apply to a filter on this partial name. Alternative you can build the entire project where this limitation would also not exists. |

Routelets does not support cTalendJob to be used inside a Routelet. |
As Routelets are more optional in nature (still important for some use cases), it is recommended to limit the Routelet to the parts where a cTalendJob call is not required and to add the cTalendJob part to the main Route(s). If this is not possible then the only good workaround is to give up on Routelets and either a) Add the Routelet parts again into each Route b) Model the Routelet as a Route using a cVM Endpoint. Then the primary Route and this supporting Route need to be deployed to the Talend Runtime as two individual Routes (firstly the supporting Route which was a Routelet before, and then the primary Route(s) which use the supporting one). This workaround only works for OSGi Deployment to Talend Runtime but not for Microservice deployment as one Microservice is one Route currently. In the case of Microservice deployment, a Socket, JMS, or REST communication would be required. |

When using Talend-LogServer, by default, event logs are stored without specific security protection and as such all logs are visible to anyone with access to the server (via an HTTP URL within your network). | For information on how to deactivate the Talend Administration Center Logging Screen and Talend Log Server, see the article about How to disable the display of log events on the Logging page of Talend Administration Center on Talend Help Center (https://help.talend.com). |

OpenID authentication only supports usernames in lower case. If the username contains capital letters, Talend STS (Security Token Service) will throw an exception that the user is not found. | If you want to use OpenID authentication, the username must be all in lower case. |

OSGi Container fails to log messages that were sent to
system.err / system.out
In the tesb.log file you will not see any messages which were sent via system.err or system.out. |
If you encounter this issue, you can run the same scenario in Console mode as the system.err and system.out will show up on the console. |
