The Instana remote sensor for IBM i uses a remote JDBC connection and a Java Toolkit remote connection. These connections use the following ports:
- 8470 - central server / license management / code page conversions
- 8471 - database access
- 8475 - remote command
- 8476 - signon verification
- 449 - server mapper if using port mapper
- 446 - for DDM/DRDA to make a remote connection to Db2 for IBM i using JDBC.
The above are non-TLS ports. Use 9xxx instead of 8xxx for TLS ports.
