When might image copies be needed in a data mirroring environment during disaster recovery?

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.
Which authorization id will be used on the remote data source REMOTEDB?

Which combination of subsystem parameter values will enable connection pooling for idle distributed database access threads?

Which action should you take to improve the performance of authorization checking for stored procedures or user-defined functions?

In complex DB2 recovery scenarios, it is important to understand the scope of which objects require recovery.
Which DB2 utility provides a list of the names of all table spaces in the table space set that is specified and a list of all the tables in those table spaces?

Which trace can be helpful in determining the resources involved with locking (i.e. deadlocks, timeouts) at a subsystem level?
