Here's a script I wrote for unix which clears the trigger flag from a
hashed file header. You could amend it for the trans log flag.
#!/bin/ksh
# clrsic.sh
# stuart boydell 2008-09-11
# clear sica bit from file header (32 & 64 bit files)
if [ $1 == '-?' ]; then
echo "clrsic"
echo "========="
echo "Clears the SICA bit from a UV file header"
echo "Usage: $0 [-?] [-f file]"
exit 0
fi
if [ $1 == '-f' ]; then
shift
FILE=$1
if [ -s ${FILE} ]; then
echo converting sica in ${FILE}
echo -n aaaaaaaa | tr "a" "\000" > sicapatchup
dd if=sicapatchup bs=1 conv=notrunc of=$FILE seek=88 count=8
rm sicapatchup
exit 0
fi
fi

Subject: [U2] need help with writing to file header
I have a need to take out the transaction logging flag inside of some
files. Can someone give me some info on how to write to the file
header.
These files that need to be changed are all hashed files and the flag
resides at hex x114. U2 tech support says this can be done in
databasic, so
any help would be appreciated.
