DB2 z/OS (mainframe) schemas-databases show up as 'null'

I am positive this is related to something incorrect in the DB2 z/OS environment, but the DBAs have not found it yet. Perhaps someone on the forum can provide insight. ... The issue is that when connecting to our development DB2, the connection is made and the schemas/databases are represented. However, all the schema/database names are displayed as 'null'. The main reason I suspect that this is not DbVisualizer related is that the same installation connects to the production environment and all is displayed correctly. There was an earlier problem that prevented connection to the development environment, and that was resolved by doing a rebind on the packages associated with the SYSIBM.SQLTABLES routine. Thoughts?

Found some additional info by turning on the monitor. ------------------------- Product Information ------------------------ Product: DbVisualizer Free 9.1.12 Build: #2306 (2014-11-27 14:36:33) Java VM: Java HotSpot(TM) 64-Bit Server VM Java Version: 1.7.0_25 Java Vendor: Oracle Corporation OS Name: Windows Server 2008 R2 OS Arch: amd64 OS Version: 6.1 ------------------------- Connected Databases ------------------------ Database Type: DB2 LUW Major Version: 10 Minor Version: 1 Profile: generic Connection Message: DB2 DSN10015 IBM DB2 JDBC Universal Driver Architecture 2.7.58 --------------------------- Debug Printouts -------------------------- [cleared] [db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned true [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString (5) called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString () returned null [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned true [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] next () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] next () returned true [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString (1) called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString () returned null [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned true [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString (2) called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString () returned SPGAAC [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned false [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString (3) called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString () returned null [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned true [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString (4) called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] getString () returned null [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () called [ibm][db2][jcc][Time:1430330643628][Thread:ExecutorRunner-pool-2-thread-4][ResultSet@4d2b72] wasNull () returned true ...
