The following topics provide information about tasks that you might need to perform before or after an upgrade of Data Integration Connectors. Post-upgrade tasks for previous monthly releases are also included in case you haven't performed these tasks after the previous upgrade.
Post-upgrade tasks for the April 2025 release
Perform the following tasks after your organization is upgraded to the April 2025 release.
File Processor Connector
After the upgrade, if you run existing or new mappings using key exchange algorithms that are not compatible with the SFTP server, you might encounter the following error:
After the upgrade, you have option to connect to the SFTP server using key exchange algorithms from one of the following JAR files located in the Secure Agent Installation directory:
•jsch-0.1.55.jar file
•jsch-0.2.17.jar file
Before the upgrade, only the jsch-0.1.55.jar file was available. To connect to the SFTP server, you might have replaced it with the later version of the JAR file that contains compatible key exchange algorithms for your SFTP server and renamed it to jsch-0.1.55.jar.
For example, you might have replaced the jsch-0.1.55.jar file with the jsch-0.1.61.jar file, and renamed it to jsch-0.1.55.jar.
In this scenario, your mappings might fail.
To run mappings successfully, use key exchange algorithms from the jsch-0.2.17.jar file by setting the UseCustomAlgorithms custom property value to 1 in the Secure Agent properties.
To set the UseCustomAlgorithms custom property, perform the following steps:
1Log in to Informatica Intelligent Cloud Services.
2Select Administrator > Runtime Environments.
3On the Runtime Environments page, select the Secure Agent machine that runs the mapping.
4Click Edit.
5In the Custom Configuration Details section, select Data Integration Server as the Service and DTM as the Type.
6Add UseCustomAlgorithms in the Name field and set the value to 1.
7Click Save.
By default, the Secure Agent uses key exchange algorithms from the jsch-0.1.55.jar file to connect to the SFTP server.
For a list of key exchange algorithms that you can use to connect to the SFTP server, see the File Processor Connector documentation.
