• Question 58:

  You execute the following SQL against the CDB (Communications Database) of your DB2 subsystem:

  INSERT INTO SYSIBM.IPNAMES

  (UNKNAME.SECURITY_OUT.USERNAMES,IBMREQD.IPADDR) VALUES ('REMOTEDB'. 'P\ 'O'. 'N',

  *123.34.45.56');

  INSERT INTO SYSIBM.IPLIST (LINKNAMEJPADDRJBMREQD) VALUES ('REMOTEDB', '123.34.45.56',

  *N');

  INSERT INTO SYSIBM.IPLIST (LINKNAMEJPADDRJBMREQD) VALUES C REMOTEDB', '123.34.45.57',

  'N');

  INSERT INTO SYSIBM.USERNAMES

  (TYPE,AUTHID.LINKNAME,NEWAUTHID.PASSWORD,IBMREQD) VALUES (T, 'USER1'.

  'USER2\ ", ,PWD2,1 *N');

  INSERT INTO SYSIBM.USERNAMES

  (TYPE,AUTHID.LINKNAME,NEWAUTHID.PASSWORDJBMREQD) VALUES ('O', 'USER1'. 'USER3', *',

  'PWD3', 'N');

  There is no trusted connection to REMOTEDB. USER1 issues a query addressing remote data source

  REMOTEDB on your DB2 subsystem.
