6. Now define the other Function IDs according to the example so far. See Figure 15-20.

## Managing zHyperlink Express 

To enable IBM DB2fi to use zHyperlinks, the DB2 zParm must be modified to enable zHyperlink, as shown in the example in Figure 15-21. 

DSNIIPA3 INSTALL DB2 - DATA PARAMETERS PANEL ===> Check parameters and reenter to change: 1 PERMANENT UNIT NAME ==> 3390 Device type for MVS catalog and partitioned data sets 2 TEMPORARY UNIT NAME ==> SYSDA Device type for temporary data sets 3 DB2 zHyperlinks SCOPE ==> ENABLE Scope of zHyperlinks I/O connections: (ENABLE, DISABLE, DATABASE, LOG) ---------------- SMS ----------------- VOL/SER DATA CLASS MGMT CLASS STOR CLASS ------- ---------- ---------- ---------- 4 CLIST ALLOCATION ==> ______ ==> ________ ==> ________ ==> ________ 5 NON-VSAM DATA ==> ______ ==> ________ ==> ________ ==> ________ 6 VSAM CATALOG, DEFAULT, ==> ______ ==> ________ ==> ________ ==> ________ AND WORK FILE DATABASE 7 LOG COPY 1, BSDS 2 ==> ______ ==> ________ ==> ________ ==> ________ 8 LOG COPY 2, BSDS 1 ==> ______ ==> ________ ==> ________ ==> ________ PRESS: ENTER to continue RETURN to exit HELP for more information 

The acceptable values for the Db2 zHyperlink Scope are: 

ENABLE Db2 requests the zHyperlink protocol for all eligible I/O requests 

DISBALE Db2 does not use the zHyperlink for any I/O requests 

DATABASE Db2 requests the zHyperlink protocol for only database synchronous read I/Os
