awk/sed script to read values from parameter files

Hi,

I am writing a shell program that executes a lot of Oracle SQL Files on different databases based on the enviroment setting value. I am trying to design a parameter file where i can store the environment values for all the databases in the below format

Environment File

File Name oraenv

# /* DB1 */
ORACLE_SID=DB1
ORACLE_BASE=
ORACLE_HOME=
PATH=
LD_LIBRARY_PATH=
.
.
Other Parameters
# /* End */
# /* DB2 */
ORACLE_SID=DB2
ORACLE_BASE=
ORACLE_HOME=
PATH=
LD_LIBRARY_PATH=
.
.
Other Parameters
# /* End */
# /* DB3 */
ORACLE_SID=DB3
ORACLE_BASE=
ORACLE_HOME=
PATH=
LD_LIBRARY_PATH=
.
.
Other Parameters
# /* End */

Master Script <-- Main Program that uses these parameters

File Name actions.sh

When the script is executed as ./actions,sh DB1 i want this to read all the parameters related to DB1 from the oraenv written between the pattern below
# /* DB1 */
.
...
..
# /* End */

create "export ORACLE_SID .." etc...

Any ideas of how best we can do this....

Thanks and Kind Regards,
Rajan.S

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
