Forum for Unix Shell Scripting ?

I an an oracle DBA working on AIX, Solaris environments. Which is the best forum to post questions on Shell scripting? I tried forums.sun.com , but replies are very slow, relatively speaking(forums.oracle.com).

I don't have access now (my employer blocks that site) but what you want to find is 'browse all of usenet', then drill down through the 'comp' domain.
Also, two very valuable books:

UNIX Shell scripting forums ???

Hi ,
Do Guys have any idea of forums for Unix shell scripting similar to oracle discussion forum one which we are using now ????
Or any links for UNIX shell scripting would be great.
Thank you so much!!!!

May be these links would give you some ideas.

PLSQL job and unix shell scripting

I want to be a plsql developer, now reading job ads for the technical requirement.
This is a typical plsql job ad:
"Technically those applying MUST have a minimum 5 years Oracle PL/SQL design and development experience combined with 3 years Informatica/ ETL exposure. You should be comfortable working off Unix platforms and associated *Shell Scripting* and database performance tuning. Experience with vendor products surrounding the compliance area such as Mantas or Actimize is highly beneficial. "
Generally, do plsql developers work with shell scripting on a basic level, like echoing, saving files, looping etc, well, this level? : Unix Programming for dummies [http://www.amazon.com/Programming-Dummies-James-Edward-Keogh/dp/0764500619|http://www.amazon.com/Programming-Dummies-James-Edward-Keogh/dp/0764500619] . Er...this kind of of shell programming is very easy, why bother even putting the requirement in the ad? It's like saying you need to know primary school maths for the job.
Or plsql developers work with unix programming at this kernel programming level, like semaphores, signal, UNIX Systems Programming: Communication, Concurrency and Threads? [http://www.amazon.com/UNIX-Systems-Programming-Communication-Concurrency/dp/0130424110/ref=sr_1_6?ie=UTF8&s=books&qid=1256350650&sr=1-6|http://www.amazon.com/UNIX-Systems-Programming-Communication-Concurrency/dp/0130424110/ref=sr_1_6?ie=UTF8&s=books&qid=1256350650&sr=1-6]
I got plsql and sql tuning requirement under control, now need your help to know what level of expertise is required for unix shell scripting. What plsql developers generally do with unix shell scripting? Can you recommend a book to read?
Many advance thanks.

Need Help in creating Unix Shell Script for database

Would be appreciable if some one can help in creating unix shell script for the Oracle DB 10,11g.
Here is the condition which i want to implement.
1. Create shell script to create the database with 10GB TB SPACE and 3 groups of redo log file(Each 300MB).
2. Increase size of redolog file.
3. Load sample schema.
4. dump the schema.
5. Create empty db (Script should check if db already exists and drop it in this case).
6. Create backup using rman.
7. restore backup which you have backed up.

This isn't much of a "code-sharing" site but a "knowledge-sharing" site. Code posted me may be from a questioner who has a problem / issue / error with his code. But we don't generally see people writing entire scripts as responses to such questions as yours. There may be other sites where you can get coding done "for free".
What you could do is to write some of the code and test it and, if and when it fails / errors, post it for members to make suggestions.
But the expectation here is for you to write your own code.

How to prepare for Converting UNIX shell scripts to PL/SQL

Hi All
I was said, that i may have to convert a lot of unix shell script to PL/SQL, what are the concepts i need to know to do it efficently,
what are the options PL/SQL is having to best do that.
I know the question is little unclear, but I too dont have much inputs about that i'm sorry for that, just its a question of how
to prepare myself to do it the best way. What are the concepts i have to be familiar with.
Many Thanks
MJ

Just how much work is involved, is hard to say. Many years ago I also wrote (more than once) a complete ETL system using a combination of shell scripts, SQL*Plus and PL/SQL.
If the PL/SQL code is fairly clean, uses bind variables and not substitution variables, then it should be relatively easy to convert that PL/SQL code in the script to a formal stored procedure in the database.
There is however bits and pieces that will be difficult to move into the PL/SQL layer as it requires new software - like for example FTP'ing a file from the production server to the ETL server. This can be done using external o/s calls from within PL/SQL. Or, you can install a FTP API library in PL/SQL and FTP that file directly into a CLOB and parse and process the CLOB.
Think of Oracle as an o/s in its own right. In Oracle we have a mail client, a web browser, IPC methods like pipes and messages queues, cron, file systems, web servers and services, etc. And PL/SQL is the "shell scripting" (times a thousand) language of this Oracle o/s .
In some cases you will find it fairly easy to map a Unix o/s feature or command to one in Oracle. For example, a Unix wget to fetch a HTML CSV file can easily be replaced in Oracle using a UTL_HTTP call.
On the other hand, techniques used in Unix like creating a pipe to process data, grep for certain stuff and awk certain tokens for sed to process further... in Oracle this will look and work a lot different and use SQL.

Reg: UNIX shell script at File Adapter

Hi all,
I am doing a File to file scenario and using command line arguments in Sending file adapter. I am using UNIX shell script ".sh" file for executing the command.
I gave the following path at "Run OS command before message processing" parameter:
/temp/xidelivery/send/FILOSC004_shell.sh
and this file contains following code:
<b>#!/user/bin/sh cp /temp/xidelivery/send/FILOSC004_in.txt /temp/xidelivery/send/FILOSC004_input_copy4.txt</b>
I put the source file, FILOSC004_in.txt and shell script files at the respective paths.
If I give "cp" command directly in command line it is working fine. But I could not execute this with shell script. Can any body give me the reason where I gone wrong.
Regards,
Pavani.

Hi,
can you try this,
bash /temp/xidelivery/send/FILOSC004_shell.sh
let me know.
hey you can check the blog below to catch the OS errors,

I want to send report generated my spooled file as attachment using unix shell script.
Can somebody help me out ?
many thanks

thanks a tonn it worked.
but i have another issue is it possible to add names in CC also ?
Also here is my code which spools the output of SP to a txt file. the File name is generated dynamically.
as shown below:
I need to send this generated file as attachement.
how do I do this? Here the shell script
=========================================================
#!/bin/sh
ORA_USER=scott
ORA_PWD=tiger
#Get the input parameter
if [ ! "$1" ]; then
STR="NULL"
else
STR="'"$1"'"
fi
#echo "exec pkg1($STR);"
#Connecting to oracle
sqlplus -s <<EOF
$ORA_USER/$[email protected]

select to_char(sysdate,'YYYYMMDDHH24MISS') dcol from dual;
spool &mydate.report.txt
exec pkg1($STR);
spool off
EOF

=========================================================
the file name will take sysdate as name so that every time a new file will be generated.
this file I need to send as attachment.

Unable to pass parameter in oracle procedure through unix shell script

Hi Experts,
I have oracle procedure where in I have to pass the value of procedure parameter through unix script.
Follwoing is the sample procedure which i tried to exceute from the unix.
Procedure:
create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) AS
sql_stmt varchar2(1000) := NULL;
v_count number := 0;
v_owner varchar2(100) := owner;
begin
sql_stmt:='select count(1) from '||v_owner||'.EMP@infodb where rownum<=10';
execute immediate sql_stmt into v_count;
DBMS_OUTPUT.PUT_LINE(sql_stmt);
DBMS_OUTPUT.PUT_LINE(v_count);
END;The script which I used is:
Unix
#!/bin/ksh
parm=$1
echo start
sqlplus -s scott@DEV/tiger <<EOF >>result_1.txt
set serveroutput on;
select '$parm' from dual;
exec owner.PRC_TESTING_OWNER('$parm');
EOFThe script is working fine that is i am able to pass to parameter value through unix shell script. :)
But if I want to pass the value of the owner in cursor , I am unable to pass this value through unix.
Following the procedure which i am trying to implement.
create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) IS
v_owner varchar2(100) := owner;
CURSOR main_cur IS
select
i.ROWID rid ,
emp_name,
deptid
from v_owner.employee;
CURSOR subset_cur(c_deptid NUMBER ) IS
    SELECT *
      FROM v_owner.DEPT d
      where d.dept_id=c_deptid;
--##main loop
FOR i IN main_cur LOOP
      FOR j IN subset_cur(i.deptid) LOOP
BEGIN
insert into v_owner.RESULT_TABLE
END;
END LOOP;
END LOOP;How can i pass parameter value of the stored procedure through unix script(that is "owner" in this case), when these parameter value is
used in cursor? :(
Can anybody help me regarding the same?
Thanks in Advance !! :D

It's not the parameter in the cursor that is the problem, it's that you are trying to use static SQL for something that won't be known until run time (the owner of the table).
You would need to use something like ...
declare
   l_owner        varchar2(30) := 'SCOTT';
   l_ref_cursor   sys_refcursor;
   type l_ename_tab is table of scott.emp.ename%type;
   l_ename_array l_ename_tab;
begin
   open l_ref_cursor for
      'select ename
      from ' || l_owner || '.emp';
   loop
      fetch l_ref_cursor bulk collect into l_ename_array limit 10;
      exit when l_ename_array.COUNT = 0;
      for x in 1 .. l_ename_array.count
      loop
         dbms_output.put_line(l_ename_array(x));
      end loop;
   end loop;
   close l_ref_cursor;
end;

Generate RMAN backup Script using unix shell script

Hello,
Could somebody give me a unix shell script that would generate RMAN script based on some user defined parameters in a config file.
e.g.
rman.conf
CHANNELS=4
USE_CATALOG=Y
DEVICE='sbt_tabe'
etc.,
many thanks,
kam

You can actually encapsulate the RMAN commands inside the shell script.
However if you really want to create a seperate RMAN script file, you can use the unix shell's "echo" command to write set variables to a file.
Thus, for example,
echo "rman target / catalog rman/rmanpassword@crcat" > RMAN_Script.rmn
echo "backup database plus archivelog" >> RMAN_Script.rmn
echo "backup archivelog all" >> RMAN_Script.rmn
creates RMAN_Script.rmn with 3 commands.

You didn't specify if you want a total time for a portion of a shell script, or the whole script in general. If you only want to know the time of the whole shell script, just reference the linux/unix built-in variable ${SECONDS}. This variable is reset for each PID.
I usually add these lines to the bottom of long running shell scripts (just before an exit code):
~~~~~~~~~~~~~~~~~~~~~~~~~
((TIME = ${SECONDS} / 60))
echo "Script ran for ${TIME} minutes. (${SECONDS} seconds total.)
~~~~~~~~~~~~~~~~~~~~~~~~~
Like I said, ${SECONDS} starts ticking from 0 when you start the script, so no need to export the variable, just reference it. The nice part is that you don't have to bother getting into sqlplus and hit the database.

Exit status running java classpath in a unix shell script

I'm new to putting java into unix scripts. I have a java classpath running inside of a unix shell script. During my testing it will error with java.io.FileNotFoundException error, which I know why that is, but when I set in my unix shell script this to see the right exit status of success/fail, it always shows a 0 for success when that isn't really the case. Below is the two lines I have set to capture the exit status and just display that exit status for now.
notifycode=$?
echo $notifycode
I have these 2 lines above on a line right below my java command in my unix shell script. How can I get my unix shell script to show the right exit status if the java classpath command fails? Thanks for any help.

That's Java code, it says "End this Java application and send return code 1 back to the shell". As for how the shell gets the return code from the application, that's a question about your shell and not about Java programming, no?

PL/SQL function - unix shell script

Hello,
I have an application that calls a unix shell script This unix shell script calls a oracle function in the PL/SQL package. For example,
In package pkg_test, there is function f_test. This function returns pls_interger.
How can I write a unix shell script to return the value from the oracle function, so that the application can get the value from the unix shell script?
Many thanks.

Thank you for your response.
The Oracle functuion pkg_name.proc_name will return different values, 0, 1, 2, 3 in diffefrent conditions.
The unix script, myscript.ksh calls pkg_name.proc_name.
The other application will call myscript.ksh and this application will need to get the values 0, 1, 2, 3 from myscript.ksh.
Can we make it without using the unix shelll function?
Thanks.
