String has * as the field delimiter and I need echo/awk to escape it, how?

Hi,

I am trying to read an Oracle listener log file line by line and need to separate the lines into several fields. The field delimiter for the line happens to be an asterisk.

I have the script below to start with but when running it, the echo command is globbing it to include other information that I don't need.

Below is a sample run of the script z.ksh

Code:
$
$ ls -altr
total 16
drwxr-xr-x 3 oracle oinstall 4096 Jan  7 03:59 ..
-rw-r--r-- 1 oracle oinstall  243 Jan  7 04:03 x.out
-rwxr--r-- 1 oracle oinstall  586 Jan  7 04:12 z.ksh
drwxr-xr-x 2 oracle oinstall 4096 Jan  7 04:12 .
$ ./z.ksh
- Processing  --> 15-DEC-2016 10:19:24 * (CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)(HOST=__jdbc__)(USER=testuser))(SERVER=DEDICATED)(SERVICE_NAME=test_app.x.y.z)) * (ADDRESS=(PROTOCOL=tcp)(HOST=60.11.22.123)(PORT=55440)) * establish * test_app.x.y.z * 12666
- timestamp = 15-DEC-2016 10:19:24 x.out z.ksh (CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)(HOST=__jdbc__)(USER=testuser))(SERVER=DEDICATED)(SERVICE_NAME=test_app.x.y.z)) x.out z.ksh (ADDRESS=(PROTOCOL=tcp)(HOST=60.11.22.123)(PORT=55440)) x.out z.ksh establish x.out z.ksh test_app.x.y.z x.out z.ksh 12666
- connectstring =
- result =
- service =
- returncode =

$ cat z.ksh
#!/bin/ksh

LOG=x.out

while read line
do
   echo "- Processing  --> $line"
   timestamp=`echo $line | awk -F"[*]" '{ print $1 }'`
   connectstring=`echo $line | awk -F"[*]" '{ print $2 }'`
   result=`echo $line | awk -F"[*]" '{ print $3 }'`
   service=`echo $line | awk -F"[*]" '{ print $4 }'`
   returncode=`echo $line | awk -F"[*]" '{ print $5 }'`

   echo "- timestamp = $timestamp"
   echo "- connectstring = $connectstring"
   echo "- result = $result"
   echo "- service = $service"
   echo "- returncode = $returncode"

   echo
done < $LOG

###########
# THE END #
###########

I've also tried doing awk -F "\*" and that does not make any difference besides giving the warning awk: warning: escape sequence `\*' treated as plain `*'

I also need to somehow extract the line below to each respective fields, i.e. CONNECT_DATA, PROGRAM, USER, SERVER, SERVICE_NAME,HOST and PORT Smilie.

Code:
(CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)(HOST=__jdbc__)(USER=testuser))(SERVER=DEDICATED)(SERVICE_NAME=test_app.x.y.z)) * (ADDRESS=(PROTOCOL=tcp)(HOST=60.11.22.123)(PORT=55440))

Here's wishing Oracle could have provided something to parse their own log. Maybe there is a program/script/utility out there that can parse log files of any format?

I will have to somehow change the timestamp to YYYYMMDD. For the time being, I need to be able to get around the asterisk globbing to start with.

Can't install Splunk/logstash unfortunately.

Any advice much appreciated. Thanks in advance.
