The JDBC driver enables you to specify synonymous connection information by using multiple setup methods (for example, DBHOST specified in the URL and PDHOST specified in HiRDB client environment definition). The following table lists the connection information items that have multiple setup methods; it also shows the priorities when items are set concurrently by multiple setup methods.
