SQL1086C An operating system error "" occurred on databasemetadata.getcolumns()

[Jairam Panickssery]

I have a simple JDBC 2.0(app driver) code snippet like:
############### ############
cSQL = DriverManager.g etConnection(sD BURL, sDBUser, sDBPasswd);
DatabaseMetaDat a dmd = cSQL.getMetaDat a();
//rs = dmd.getColumns( null, null, tableName.toUpp erCase(), null );
rs = dmd.getColumns( null, "DB2INST1", tableName.toUpp erCase(), null
);
############### ############

When I run this against my db2 database:
############### ############### #
Database Name DB2/6000
Database version :07.02.0006
Driver Major Version :7
Driver Minor Version :1
############### ############### #

I get this stack trace:
############### ############### ##############
COM.ibm.db2.jdb c.DB2Exception: [IBM][CLI Driver][DB2/6000] SQL1086C

Has anyone seen this before ?

Thanks in advance,
