Wanted to create two indexes in parallel in two different tables so tried the following

q1.sql (file has the following contents)
connect to db;
create index i1 on t1(c1);

q2.sqlfile has the following contents)
connect to db;
create index i1 on t1(c1);

run.ksh(script has the following contents)
nohup db2 -tvf q1.sql &
nohup db2 -tvf q2.sql &

When executed as run.ksh > run.ksh.out it produces the following
DB21018E A system error occurred. The command line processor could not
continue processing.
DB21018E A system error occurred. The command line processor could not
continue processing.

What is the cause of this ? Env: AIX 5.3/DB2 9.1/Korn Shell

Typo error earlier:
q2.sql (file has the following contents)
connect to db;
create index i2 on t2(c1);

I've simplified it a bit:

Script run.ksh contains:
nohup db2 -tvf q1.sql &


q1.sql contains:
connect to test;


The script will generate the error mentioned above, DB21018E


If I execute "nohup db2 -tvf q1.sql &" from the command line, then it works ok.

Modified run.ksh to have:
nohup db2 &


This modified script also generates DB21018E, but the command executes ok from the command line.

The following works:

Using two scripts

run.ksh.b contains:
run.ksh.a &


run.ksh.a contains:
nohup db2 -tvf q1.sql
nohup db2 -tvf q2.sql
