Hello,
Can DBConnect connect to DB2 running on Windows ? or it only works with DB2 running on Linux ?
DB Connect doesn't care about the platform of the target database.
On below link, it says 'IBM DB2 is supported when the database is running on Linux. Splunk doesn't test or support DB2 on AS/400 or Windows'
Doesn't that mean it's not supported and may not work ?
https://docs.splunk.com/Documentation/DBX/3.4.2/DeployDBX/Installdatabasedrivers
"Not supported" is not the same as "doesn't work". It means Splunk won't help you if it doesn't work. Try it. If it works then great; if not then write a modular input that does the same thing.
