Attempting to query to a 3rd party historian through their JDBC driver I ran into a few issues.
Running a named query or a perspective based system.db.runQuery against this driver yields this error:
caused by NoSuchMethodError: sun.nio.ch.DirectBuffer.cleaner()Lsun/misc/Cleaner;
Running a query within Vision, the Script Console, or the Database Query Browser yields the expected returned results, though I receive a HttpChannel warning in the gateway for the same error as above.
Within the Database Query Browser and Named Queries I also cannot browse through tables, which yields the error:
“GatewayException: Unable to read response from Gateway.
caused by org.xml.sax.SAXParseException; lineNumber: 3; columnNumber: 11; The end-tag for element type “Response” must end with a ‘>’ delimiter.”
I am leaning to this being a problem with the JDBC driver, but considering it will probably not be updated for Java 11 anytime soon, I am hopefully that it is not, or at least that I will be able to run queries within Perspective with the gateway warning as it seems like I can do in Vision. The driver claims it is compatible with Java 8-10.
