Supported Oracle Java version

Does anyone know if there are any issues running Ignition 7.9.12 using Oracle Java 8 update 291 64 bit? A customer tried updating from update 144 and Ignition would not boot. They ended up having to roll back the update to get it working again.

The Ignition server is running on Windows Server 2012.

Do you have wrapper logs from when it wouldn’t boot?

The only issue I’m aware of is that newer versions of Java disable the now deprecated and insecure TLS 1.0 and 1.1 in their default configuration, which has caused problems for customers with older versions of SQL Server that don’t support TLS 1.2. This doesn’t prevent the gateway from starting though.

The logs had gone by the time we were told. I’ve asked the customer to involve us when they try to upgrade it again (no SQL Server thankfully!). If it fails this should give us the chance to have a look at the logs.

It turned out the issue was that although Ignition worked, it wouldn’t connect to any database. We had to separately upgrade the MySQL Connector/J driver, after which everything worked.
