QUESTION 3
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’);
