Well, quite possibly a lot. Is this for POSIX sh? If you have bash, you could use arrays instead of eval.

You should quote every "$variable".

You can test a command, rather than assign "$?" to a variable and test the variable... if takes a command ...

You should read your fields into separate values using read instead of `echo "$line" | awk '...'` ...

You write a "list.txt" but read a "list"

Taking all this into account, plus I don't think we need "split", I rewrite it as so:

Code:
#!/bin/sh
file='full_refresh.txt'
schema=schema
table=table
nickname=nickname

# i don't have this function...test
db2() {
        echo "db2: $@"
        #pretend like it takes some time
        sleep 10
}

full() {
        echo "You entered full $1,$2,$3"
        if db2 "call util.DATA_REFRESH('LOAD','$1','$2','$3','$2','R','?',?)"; then
                echo "$1.$2" >>Success_list.txt
        else
                echo "$1.$2" >>failure_list.txt
        fi
}

while IFS='|' read schema table nickname _; do
        count=$((count+1))
        full "$schema" "$table" "$nickname" &
        if [ "$count" -ge 4 ]; then
                wait
                count=0
        fi
done < "$file"
