Hi.

I tested this and it works.

Please provide the following:
  • The exact code you are running
  • ls -l of /var/opt/oracle/oratab2
  • cat of /var/opt/oracle/oratab2
  • echo $oraserver
  • The exact output when you run the code.
Thanks.

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.

# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.

+ASM1:/opt/oracle/product/11.1.0/racasm:N
abc:/opt/oracle/product/11.1.0/racdb:N
def:/opt/oracle/product/11.1.0/racdb:N
ghi:/opt/oracle/product/11.1.0/racdb:N
jkl:/opt/oracle/product/10.2.0/racdb:N

orahome=$(awk -F: '$1 == "'$oraserver'" {print $2}' /var/opt/oracle/oratab2)
ORACLE_HOME=$orahome;export ORACLE_HOME

and it's returning ORACLE_HOME =''

I also tried like this ...



oracle@testserver:/opt/dba/oraadmin/tools DEV$ awk -F ":" '$1 == "'hmtrid1'" {print $2}' /var/opt/oracle/oratab

oracle@testserver:/opt/dba/oraadmin/tools DEV$

Thanks

Hi talashil.

I've just tried it (again) in bash and it works.

The only thing I've learnt here is that I'm adding bash to my list of shells that I actively dislike! Give me the nice ksh (vi) editing command-line ways anyday!

Here's what I did:

I created a file called oratab2, adding what you said:
Code:
+ASM1:/opt/oracle/product/11.1.0/racasm:N
abcd1:/opt/oracle/product/11.1.0/racdb:N
xyz1:/opt/oracle/product/11.1.0/racdb:N

I set the variable oraserver:
Code:
oraserver=+ASM1

I ran the awk statement:
Code:
awk -F: '$1 == "'$oraserver'" {print $2}' oratab2

I got the output:
Code:
/opt/oracle/product/11.1.0/racasm

This works in ksh and bash.

If you really want tortured command-line editing, you can use "set -o vi" in bash, just as I can get an almost-usable command line in ksh with "set -o emacs".

I confess it was a cheap shot, and didn't add to the "knowledge base", but when you spend 90% of your life pressing escape-k, the up arrow just isn't where it needs to be when you need it!

Strange, here the script is working fine using ksh93, bash, dash(sh) and zsh
