Determining if network is up from shell script?

Is there a way using a shell script to tell if unix thinks the network is up? I have a 3rd party PCMCIA wifi card that takes a few seconds to reconnect to the network on wake or boot (utility needs to launch and synch get established) and I'd like to trigger a script once it has reconnected. (I have no way of asking the card itself -- the driver/utility isn't scriptable.) It's clear someplace in unix knows it's not up right away because the logs show a few "network not up" (or something like that) messages for awhile (DNSResponder I believe may have been associated with some of them) right after the wakeup is logged. The GUI network status for the port (whether that'd be knowable from the shell or applescript or not) doesn't reflect that the connection isn't up -- it shows green for the port right away, presumably because the card itself is responding.

Here's a similar approach but waits for the specified interface to become active:
<pre style="padding-left: .75ex; padding-top: .25em; padding-bottom: .25em; margin-top: .5em; margin-bottom: .5em; margin-left: 1ex; max-width: 80ex; overflow: auto; font-size: 10px; font-family: Monaco, 'Courier New', Courier, monospace; color: #222; background: #eee; line-height: normal">#!/bin/sh
while [ "`ifconfig | sed -n '/^'$1'/,/^[a-z]/ s/.*status: $.*$$/\1/p'`" != "active" ]
do
echo interface $1 is not up
sleep .5
done
echo interface $1 is now UP
</pre>
Save it as ifup, make it executable, and call it with the name of your interface:
ifup en1

Problem while calling concsub from shell script

Hi All,
I am facing problem when I am trying to run CONCSUB utility from shell script.The same works well when I try it from command line.The only prob I am facing from shell script is assigning values to temporary variables.
This is how my script looks
#!/bin/bash
export PARM5="$5"
export PARM6="$6"
export PARM7="$7"
echo "INTPARM5=\"$PARM5\""
echo "INTPARM6=\"$PARM6\""
echo "INTPARM7=\"$PARM7\""
echo $FND_TOP/bin/CONCSUB $1 ONT 'Order Management Super User, Vision Operations (USA)' $3 WAIT=Y CONCURRENT ONT $PROGRAM "$INTPARM5" "$INTPARM6" "$INTPARM7"When I try to run the above shell based concurrent program it doesn't pass the parameters as expected and it errors out saying "Wrong number of arguments to call the procedure"
I tried my luck from some of the previous posts ({thread:id=2360776} ),but to vain
If anyone has any ideas,please suggest!!
Thanks in advance!!

Passing parameters from shell script to OWB process flow

Hi all,
I am running OWB process flow (using the template script provided by oracle) and i want to pass two date parameters as shown below:
sqlplus -s $SQL_USER/$SQL_PWD@$ORACLE_SID @$HOME_DIR/src/vmc_oem_exec_script.sql OWB_OWNER VMC_POST_DW_PF_LOC_SIT PROCESS VMC_NM1_PORT_MAIN "," "P_DATE_FROM=$DATE_FROM,P_DATE_TO=$DATE_TO"
How do i catch those values in process flow and pass those to mappings in Process flow?
Do i need to create PF variables with same names or any name will do?
Thanks in advance

This document is explaining how to pass data between activities in process flow.
I am passing parameters from a shell script.
Any ideas,how to pass parameters from shell script and then initialize the process flow variables based on those values and then pass them further to mappings.
Thanks

Identify Network Card Type by shell script.

Hi Everyone,
I am currently rolling out ML to about 300 Macs and as a side issue I need to identify the make and model of the network card in each machine, due to incompatibilty with some network switches.
Does anyone know how I can get the make and model of the network card by a shell script rather than having to visit each and every machine.
Regards
Chris

Thanks Linc,
That solved my issue. Far better than having to visit hundreds of machines spread over hundreds of kilometres.

Urgent Problem in Executing perl script from shell script

Hello,
I've a shell script on one server (source) and a perl script on another (target).
My perl script will check whether the directoryname, filename provided by shell script exists on the target server or not.
My shell script is as follows:
#! bin/bash
cmd=`ssh user@target "perl /home/user/test_dir/validate_file.pl"`
echo $cmd
And my perl script uses a package CU_Functions.pm, which is in the same directory as the perl script on the target server.
But when I invoke the perl script from shell script, I get the following error:
Source:user> (db:ias10g12_mid_db) /home/user/perl
$ sh /home/user/arcs/arcs_conn.sh
user@target's password:
Can't locate CU_Functions.pm in @INC (@INC contains: /local/perl-5.6.1/lib/5.6.1/i686-linux /local/perl-5.6.1/lib/5.6.1 /local/perl-5.6.1/lib/site_perl/5.6.1/i686-linux /local/perl-5.6.1/lib/site_perl/5.6.1 /local/perl-5.6.1/lib/site_perl .) at /home/user/test_dir/validate_file.pl line 13.
BEGIN failed--compilation aborted at /home/user/test_dir/validate_file.pl line 13.
Please let me know if I need to do any configurations prior to call the perl script.

As for the Perl INC, I cannot recall the environment variable that sets that but the following example should work:
ssh user@host "export ENV_VAR=/path/to/include/files:$ENV_VAR ; /full/path/to/script"

Exports (from shell script) without password given explicitly in script

Hi All,
I have Oracle 10g2 on SLES 10 64-bit. I would like to do export the database using data pump from shell scripts. Is there any method to hide the password in the script file.
Currently in doing by command:
expdp system/password@database ....
So any user who see the script will know the passowrd.
Regards
Groxy

Hi,
Have you considered the "Secure External Password Store" feature that was added in 10gR2? It uses the Oracle Wallet to store a database_alias with username/password credentials in encrypted format. Then you can enter your expdp command like this:
expdp /@database_alias ...
Take a look at the 10gR2 Security Guide. There's a chapter there on how to set this up.

Error in calling SQL plus program with parameter from Shell script

This is my Shell script. I am trying to call in the SQL plus program with the parameter and the shell script is registered as a concurrent program.
PARAMETERS=`echo $1 |tr -d '\"'`
DB_USER_ID=`echo $PARAMETERS|cut -d" " -f3|cut -d"=" -f2`

timestam=`date +%y-%m-%d`
sqlplus -s $CONN_STRING @ar_statement.sql $REQ_DATE
chmod 755 statement.sh

My Sql plus program is like this.
set pagesize 0
set heading off
set feedback off
spool $GEC_TOP/log/ge_ar_statement.sh
select output_file_name
from fnd_concurrent_requests
where trunc(actual_completion_date) = '&2';

When i run the concurrent program, i am getting the following error:

I am not strong at Unix Porgamming and i would request someone who can
help me out as soon as possible.
I need this solution quickly and thank everyone in advance.
Thanks.

Can you put your coding between code statements, like shown in the FAQ. It will be easier to read.
Looking at your script, my first guess is that crontab will not find your sqlplus since your script does not have $HOME/bin in the $PATH. From what I understand, running .profile in your script will not work either because variables are exported to sub-shells, not to the shell above. You can call your script with a dot like . ./script which means that the script will run like it was typed at the command prompt. But it will be less confusing to define appropriate variables in the script. eg.
ORACLE_SID=my_instance_name
ORACLE_HOME=/my_path_to_oracle_home_directory
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$ORACLE_HOME/bin:$PATH
I remember some slightly different way of coding to handle the sqlplus return codes.
For instance:
sqlplus -s /nolog > /dev/null <<-EOF
connect system/manager
@ssm.sql
whenever oserror exit failure
whenever sqlerror exit failure
EOF
sql_err=$?
if [ $sql_err -ne 0 ]; then
echo "FAILURE"
else
echo "SUCCESS"
fiThe - in -EOF supresses tab's
Using connect will prevent ps from showing your login credentials
In some versions of bash the ending EOF needs to be at the beginning of the line to work.

Btw, if you "source" a script running it like . .script, than an exit in that script will log you out.

Displaying an alert (Applescript or otherwise) from shell script?

I have a point in a shell script where I'd like to put up an alert dialogue on a particular error condition. The script runs in the background and doesn't have a terminal window. I tried writing a little applescript that uses the applescript alert command and call it using osascript from my shell script, but it doesn't work. If I enter "osascript ~/myscript.scpt" in a terminal window, I get the error message "/Users/Ted/myscript.scpt: execution error:No user interaction allowed. (-1713)" (If I run myscript.scpt from the script editor it does what I want it to do.) Any ideas? I suppose I could have my shell script create a file in some folder and have my applescript be triggered as a folder action, but that seems pretty roundabout!

Thanks -- I apologize for not doing a more thorough search! Yes, that comes very close to addressing my need, but I have run into one difficulty. If I run my shell script from the terminal (pasting it in) everything works fine. If I run it as a packaged app (with Platypus) everything works like it's supposed to, except that the alert applescript (it's just a one line script) briefly flashes the alert dialogue when it's supposed to and then dies, rather than waiting 10 seconds or until I click OK. I'll have to experiment and see if I can tell what's going on.

Calling sql script from shell script

Hi,
I know this question has been asked many time in various forums, but I tried many combinations and not able to figure out what I'm missing.
Basically - I'm trying to call a sql script from a shell script.
This is my sql script (plsql.sql) -
DELCARE
v_empno NUMBER := '&empno';
BEGIN
select ename,sal from emp where empno = v_empno;
dbms_output.put_line('Inside the plsql file');
END;
This is my unix shell script - I'm caling the plsql.sql file with the parameter passed(97882). I don't get any output. at least I should be able to view the dbms output if not for the sql query inside the sql script.
#!/usr/bin/ksh
sqlplus -s sam/olo01 << HERE
@plsql.sql 97882;
HERE
What is it I am missing ?

Using your scripts (and having to create and populate a table myself, that would have what your select statement implies),
oracle:oklacity$ cat plsql.sql
DELCARE
v_empno NUMBER := '&empno';
BEGIN
select ename,sal from emp where empno = v_empno;
dbms_output.put_line('Inside the plsql file');
END;
oracle:oklacity$ cat doit.sh
#!/usr/bin/ksh
sqlplus -s sam/olo01 << HERE
@plsql.sql 97882;
HERE
oracle:oklacity$ ./doit.sh
SP2-0042: unknown command "DELCARE" - rest of line ignored.
SP2-0734: unknown command beginning "v_empno NU..." - rest of line ignored.
oracle:oklacity$
This is the kind of information you should have put in your opening post.

Unable to see the sql serveroutput from shell script

Hello experts,
I have a shell script which I am using to call a pl/sql proc.
This proc writes to dbms_output.
I would like to capture the dbms_output to a file when calling sqlplus from my shell script.
Here is the code:

echo "
sqlplus apps/$APPS_PWD << ENDOFSQL
set serveroutput ON
set feedback off
set verify off
set linesize 250
set pagesize 250
begin
jdr_utils.listcustomizations('$i');
end;
exit
ENDOFSQL
" >> new.log
===============================
What I get in the 'new.log' is given below:
===============================
sqlplus apps/prj08app << ENDOFSQL

set pagesize 250
begin
jdr_utils.listcustomizations('/oracle/apps/irc/candidateSelfService/webui/VisVacDispPG');
end;
exit
===============================
ENDOFSQL
What I would like to get is the dbms_output given by the procedure.
Please suggest.

VinodYou need to realize & understand that EVERY command line command runs in its own separate OS process.
So the results from DBMS_OUTPUT get sent to Standard Out for the sqlplus process; which is NOT attached to your terminal.
The bottom line is you can't get there from here.
