If you have used default settings while installing DB2 on AIX. You have created db2inst1 user to use and access DB2. This post is related to the scenario, when a root user have to execute a shell script containing a store procedure of DB2.
Create a shell script with following contents. Your every statement will be run with su to db2inst1.
#!/bin/sh su - db2inst1 -c 'db2 connect to customerdb user db2inst1 using admin' su - db2inst1 -c 'db2 -tvsf /u01/IBM/workspace/addcustomer.sql'
Write any thing in your SQL file. I am calling a DB2 store procedure that will insert a row in a table.
Running being a root user.
bash-3.2# ./addcustomer.sh Database Connection Information Database server = DB2/AIX64 9.7.0 SQL authorization ID = DB2INST1 Local database alias = CUSTOMERDB call ADDCUSTOMER() Return Status = 0
