Hello,
When i use jt400.jar for connect to my AS400 (BRU) database i would select and view only one libraries (LOUPS) not all (1122 libraries in as40) i use this url :
jdbc:as400://BRU;libraries=LOUPS;
But software like dbeaver always show all LFB;libraries
Sorry, there is nothing that can be done. I suspect dbeaver is using the database metadata API's to request the list of the schemas on the database. The system is returning the list because there are a lot of schemas on the system.
