Notes to self - Setting up DB2 Client connectivity

It's been ~10 years since I last did this ( DB2 on Unix to DB2 on z/OS or OS/400 ), but I now have a requirement to deliver a DB2 client for WebSphere MQ interaction ( MQ will use ODBC rather than JDBC ).

I knocked this up using a pair of VMs on my Macbook .....

Response File -  ~/db2client.rsp

PROD                      = CLIENT
FILE                      = /opt/ibm/db2/V10.1

Install DB2 Client Binaries - as root

./db2setup -r ~/db2client.rsp

Create DB2 User and Group - as root

groupadd db2users
useradd -g db2users -d /home/db2user1 db2user1
passwd db2user1

Create DB2 Instance ( required for client connectivity ) - as root

/opt/ibm/db2/V10.1/instance/db2icrt -a CLIENT db2user1

Catalog Remote DB2 Server ( Node ) - as db2user1

db2 catalog tcpip node rhel6 remote rhel6 server DB2c_db2inst1

( node and remote refer to DB2 server hostname, server refers to DB2 service name in /etc/services )

Validate Node Directory

db2 list node directory

Test Connectivity - as db2user1

db2 attach to rhel6 user db2inst1 using passw0rd
db2 list applications
db2 detach

Catalog Remote Database - as db2user1

db2 catalog database foobar at node rhel6

( database refers to database alias on remote server, node refers to previously catalogued node )

Validate DB Directory - as db2user1

db2 list db directory

Create Database on Server - as db2inst1

db2 "create table snafu(surname char(16) not null,firstname char(10) not null)"

Use Database - as db2user1

db2 connect to foobar user db2inst1 using passw0rd
db2 list tables for all | more
db2 "select * from db2inst1.snafu"
db2 "describe select * from db2inst1.snafu"
db2 "insert into db2inst1.snafu(surname,firstname) values('Hay','Dave')"
db2 "select * from db2inst1.snafu"
db2 terminate

Shiny :-)

Yay, VMware Fusion and macOS Big Sur - no longer "NAT good friends" - forgive the double negative and the terrible pun ...

After macOS 11 Big Sur was released in 2020, VMware updated their Fusion product to v12 and, sadly, managed to break Network Address Trans...
