UNIX - How do you make a script continue after a & (starting another background PID)

Hi folks,
Hopefully someone on here can lend a hand with this. I'm trying to start DB2 in a script because DB2 was originally starting in inittab. By moving the DB2 commands from inittab to a script, I can reboot the LPAR to stop DB2, take a mksysb without DB2 running, then start DB2 with a script afterwards. The problem is... one of the DB2 commands has to continue running in the background, so I put a & at the end and this is hanging up the script. I have press Enter for it to continue.

The first DB2 line, which starts the DB2 services, executes fine:

/etc/rc.db2 > /dev/console 2>&1

However, this second line, which starts the DB2 fault monitor, requires to start it in a background process (hence the & at the end). This is causing my script to halt and I have to press Enter for it to continue:

usr/opt/db2_08_01/bin/db2fmcd &

I have much more starting after DB2 (MQ, iWAY, and WAS) so I need a way for the script to keep going. Anyone know how to overcome this?

Forgot to mention, I'm using AIX 5.2 Version and TL 5200-09.

Thx
