What's new in 17.4.8?
Stambia Published Web Services Asynchronous invocation
Stambia Published Web Services now support to be called in an asynchronous mode when invoked through HTTP REST.
When doing this, the session will be started on the Runtime and the Web Services call will hand back to the user without waiting it to finish.
This offers the possibility to start time consuming sessions without being locked on the client side.
To perform this, simply call your Stambia Web Service with an additional X-asynchronous=true HTTP header to the request.
Refer to this article for further information.
Ability to use the PATCH method in REST Web Services Invocations
This is now possible to use the PATCH method when invoking REST Web Services.

What's new in 17.4.7?
Bug fixes
This version fixes a bug on database saved Metadata Variables with large string values.
When storing large values, there was issues when retrieving them: they were truncated on some databases.
This issue should not happen anymore.
The full changelog of this version can be found here.
What's new in 17.4.6?
Get files with FTP can be binded
The Get Files with FTP Process Action now supports being the source of a bind.
This means that you can now bind the result of the action to another one and retrieve through all the information about the retrieved files.
The bind variables available are the same as the ones which are stored in the table created when drag and dropping a database schema on the action.
The complete list can be found in the action's reference documentation.
What's new in 17.4.5?
Runtime security: ability to specify an anonymous user
When Runtime security is enabled, there is now the possibility to define an anonymous user, with its specific permissions.
This offers the ability to authorize anonymous connections (without user / password) with restricted permissions on secured Runtimes.
This allows for instance to allow anonymous connections only for consultation:
<user anonymous="true" roles="Connect View"/>
Refer to this article for further information.
XML Reading performance improvements
We've made some improvements on the action used to read XML files, proving better performances.
This will mostly impact the XML templates using the export functionality, such as the 'Load XML to Vertica' one, but it also features improvements for common XML Reading.
You may therefore notice performances improvements on your treatments reading XML files.
New parameter supported for the Execute delivery Action
A new parameter is supported on the Execute Delivery Process Action: 'Deliv Remote Delivery Mode':
When 'Deliv Engine Host' and 'Deliv Engine Port' parameters are set, by default the execute delivery action is looking for the delivery in the Runtime executing the action.
This option offers the possibility to specify that the delivery should be searched in the remote Runtime instead (the one defined with the parameters).
In this case, the delivery file must be present in the remote Runtime.
New parameter in Execute Delivery Command
The execute delivery command was missing the possibility to specify the session name to use for the execution.
This isn't the case anymore!
The 'sessionName' parameter is now available to define it as you want.
execute delivery mydelivery sessionName mySessionName

Reorganization of the Runtime's Configuration files
All the files located under the <stambiaRuntime>/properties/ folder has been reviewed and reorganised.
- All the configuration is now centralized in one file: engineParameters.xml
- Comments, descriptions, and examples have been added to illustrates the available and possible options
- Several samples have been added in the <stambiaRuntime>/properties/samples/ folder to make easier the understanding of the configuration through examples
Notes
- Configuration files from previous versions will continue to work.
- The parameters can still be externalized in dedicated files if needed.
Java additional Options
In addition, Java additional options, usually set with the -Doption01=value01 argument on the Java command launching the Runtime, can now be specified directly in the Runtime's configuration file.
Refer to this article for more information.
Security
User restriction and roles
The connection to the Runtime can now be secured with a user / password.
This new functionality offers the possibility to define a list of users, with specific roles, that can connect and make operations on the Runtime.
Refer to this article for more information.
Prerequisites:
Stambia DI Designer S18.3.0 or higher is required to connect to a Runtime secured with a user / password.
Hostname / IP restriction
The connection to the Runtime can now be restricted to a list of allowed hostnames / IP addresses
Refer to this article for more information.
Load balancing / Failover
Runtime clustering
A new system has been introduced to allow the configuration of a native load balanced pool of Runtimes with failover management.
When configured, the sessions executed on the cluster will be automatically load balanced to one of the Runtimes with the chosen method.
Failover Runtimes can also be defined to take over the executions when the main Runtimes are unavailable.
Refer to this article for more information.
Auto-Restart of sessions
The sessions can now be configured to be restarted automatically when errors are detected.
The delay and the number of restarts can be specified directly in the Processes.
Refer to this article for more information.
Web Services improvements
Stambia Web Services improvements
Input / Output / Fault temporary files deletion
Three new configuration parameters have been added to manage the Input, Output, and Fault temporary files generated during the invocation of a Stambia Web Service.
They offer the possibility to choose if they should be kept or not, or only when an error occurred during the invocation.
Refer to this article for more information.
URL Path Parameters
Parameters defined directly in the Input URL's path can be used as Input parameters.
E.g http://stambia:42200/rest/StambiaDeliveryService/2/myDelivery/id/3
In this example, 'id' and '3' can be retrieved in the Web Service's Process.
Refer to this article for more information.
Input and Output HTTP Headers
Input and Output HTTP Headers can be defined in Stambia Web Services.
Refer to this article for more information.
HTTP Response Code
A new META-INF allows to customize the HTTP Response code returned by the Web Service.
Refer to this article for more information.
Web Services Invocation improvements
Response HTTP Headers
The HTTP headers returned after a Web Service invocation can now be retrieved and stored in a database.
They can be defined under the Output node of the WSDL Metadata, and then mapped as usual in the Mappings.
Refer to this article for more information.
HTTP Response Code and Message
As the HTTP Headers, the HTTP Status code and HTTP Response Message returned by a Web Service can now be retrieved and stored in a database.
They can be defined in the Output of the WSDL Metadata and then mapped as usual in the Mappings.
Refer to this article for more information.
Customizing the HTTP Verb at invocation
The HTTP Verb used when invoking a Web Service, such as POST, GET, PUT or DELETE can now be specified directly in your Mappings.
This allows to dynamically choose the HTTP Verb used at execution.
Refer to this article for more information.
JSON and XML improvements
Property Fields
A new type of field has been introduced in the Stambia's JSON and XML technologies, called "Property Field".
This new type of field offers the possibility to retrieve dynamically the information about the JSON and XML files at execution, such as the file name, size, or path.
It moreover allows to load dynamically JSON or XML nodes' name at write.
Refer to the following articles for more information:
Name Selection Pattern
It is now possible to read JSON and XML files which contain nodes with varying name.
This specific case happens when the nodes do not have a generic name like 'customer' for instance but data information instead.
E.g. The name of the node below is the name of the person:
{
"json_person": {
"GIBBS": {
"id": 1,
"firstname": "Jason",
"lastname": "GIBBS",
"company": ""
}
}
}
Refer to the following articles for more information:
Reading multiple files
This version introduces a new feature that allows to read multiple JSON or XML files at the same time.
It consists of using masks in the file's path, such as:
D:/folder/customer*.json|exclude::D:/folder/customer2.json
This offers the possibility to load a bunch of files with the same structure.
Refer to the following articles for more information:
File Driver improvements
Ending lines to skip
A new parameter has been added on the File Metadata to specify a number of ending lines to skip when reading the file.
This is particularly useful on files containing footers for instance.
Filtering a range of records
The filters available on the File Metadata have two new parameters that offer the possibility to specify the range of record to process.
This allows to filter the lines when loading files.
