SAP NOTE 663756 DB6 Multiconnect to DB2 for zOS- DB2 for i or IDS databases-CLI
SAP NOTE 160484 - DB2/390: Database multiconnect with EXEC SQL
setup DBCO connection from NetWeaver 7.5 with Db2 LUW 10.5 to remote server DB2 9.1 on z/OS (mainframe)
1) use 3270 emulation to find . . .
1.1) SSID
1.2) LOCATION
1A) start Open Text . . . host explorer . . . hostex32
1B) choose 3270 emulation
notice SSID: DB2F upper right corner -DISPLAY DDF DETAIL notice LOCATION: 
2. Binding CLI bind files for the target database
This step is only necessary for DB2 z/OS target databases.
2a. Log on to DB2 LUW command line session in putty as user <sapsid>adm
2b. Go to the directory where the bind files reside.
If you use DB2 LUW as the primary database, the bind files typically reside on the database server
in the following directory: ~db2<dbsid>/sqllib/bnd
2c. Set the environment variable DB2_CLI_DRIVER_INSTALL_PATH to the CLI driver base directory as follows:
setenv DB2_CLI_DRIVER_INSTALL_PATH /usr/sap/<SAPSID>/SYS/global/db6/<your OS>/db6_clidriver/?
tcsh:root@benz:/> echo $DB2_CLI_DRIVER_INSTALL_PATH
DB2_CLI_DRIVER_INSTALL_PATH: Undefined variable.
tcsh:root@benz:/> setenv DB2_CLI_DRIVER_INSTALL_PATH /usr/sap/X5D/SYS/global/db6/LINUXX86_64/db6_clidriver
tcsh:root@benz:/> echo $DB2_CLI_DRIVER_INSTALL_PATH
/usr/sap/X5D/SYS/global/db6/LINUXX86_64/db6_clidriver
tcsh:root@benz:/>
2d. Bind additional packages as follows:
DB2 for z/OS: db2cli bind @ddcsmvs.lst -database <DB name>:<DB host>:<DB port> -user <user> -passwd <password>
Here is how it looks using an SAP in-house sandbox system with hostnm=benz and <SID>=X5D

cat /etc/services | grep -i sapdb2

tcsh:<sid>adm@<hostnm>:/db2/db2<sid>/sqllib/bnd> db2cli bind @ddcsmvs.lst -database <SID>:<hostnm>.<fqdn>:<db2luw_port> -user db2<sid> -passwd <db6_pwd>

3. Configuration in DBCON table
/oDBCO
Display -> Change (Ctrl+F1)

-------------------------------------------------------------------
Connection DB2XXXX successfully opened.
Connection DB2XXXX closed
5. Create logical system for DBCO connection DB2 MALC
/oBD54
6. /oRSA1
under DB Connect
right click and “create”
enter /select logical system created in step 3. Above
enter DB type . . . DB2 . . .
select connection entry . . . . DB2MALC ( basically assign/mapping logical system DB2MALC with DB Connection DB2MALC)
7. RSDL_META_UPLOAD
/oSE38
execute RSDL_META_UPLOAD
select logical system
use gui to display tables and table data in that remote server / db connection
