Does CA TDM 4.9 version supports the TLS 1.2 encryption and identify the steps to upgrade it to avoid any impact on connections between application and DB2 database(hosted on AIX server)?
Release : 4.9.1
TDM Portal 4.9.1, out of the box, comes with TLS1.2 supported and enabled. There isn't anything special you have to do on the TDM side for Portal.
You can confirm this by checking the C:\Program Files\CA\CA Test Data Manager Portal\tomcat\conf\server.xml file. Check the 8443 connector. The sslProtocol parameter should be set to TLSv1.2.
If you are wanting to mask DB2 data using TLS1.2, I recommend going out to the following site, and downloading the latest FDM release:
At this page, select the FDM 4.9.1 link, at the top section of the page, and this will jump you to the FDM 4.9.1 patches. Download the latest patch, and upgrade your FDM installation by running the patch installer. You may also want to do the same for TDM Portal, and get the latest Portal patch install.
When using FDM to mask DB2 databases that have been configured to use TLS1.2, you would need to provide the additional properties to establish the connection. See https://knowledge.broadcom.com/external/article?articleId=222429 on how this should be set up.
You will need to have your DB2 DBA ensure DB2 is configured to use TLS1.2, and if there are any Certificate Authority assigned certificates, those will need to be added to the TDM Portal keystore, or truststore.
