Hi ,
I am into the situation where I need to generate the statspack every 30 min. I want to automate this this task by writing the shell script, unfortunately i am poor in shell script
do anybody have script which can implemment this functionality , I am facing problem that when spreport is called then how it will automatically pick up if start snap ID and end snap ID which should for 30 min duration.
Any quick help shell be highly appreciated. Thanks in advance.

Amitdo you realize that "shell script" is Operating System (OS) dependent?

i am working on RMAN in test environment.
beacuse there in no redo generation or very minor redo generation. i want to write a shell script that runs through cron jobs after a specific period of time and generate redo logs . This i want to do for checking RMAN mechanism of backing up archivelogs and also deletion confirmation of archivelogs through rman;
i write a script but it is not generating redo logs

That's because sqlplus never sees the statement ... think about how your shell script is proccessed. Walk through it line at a time.
>

Moreover have a look on script as well.
I've copied your script below and added line-by-line comments to help you see it the way the shell sees it, Each line of your code is followed by my explanation of how the shell sees that line and what it does with it.

Ok, maybe you gave up and gave sqlplus an exit command, so the shell can now continue with the next line
sql 'alter system switch logfile';shell will try to locate an executable file call "sql" and pass it the command line parm "alter system switch log file". Do you have an executable called "sql" to process that command line parm? You probably saw something like:
./doit.sh: line 5: sql: command not found

/and again, the shell really doesn't know what to do with this.

exitFinally the shell sees a command (exit) it recognizes.
I did all the above to help you see why it wasn't working. The solution is to use input redirection to feed your sql commands to sqlplus.
#!/bin/sh
export ORACLE_HOME=/opt/dev/oracle/db/tech_st/11.1.0
cd $ORACLE_HOME
. ./TEST_testing.env
sqlplus / as sysdba <<EOF

Executing a shell script from a Trigger

All,
I have to write a script to do the following requirement.
There is a file called BUSINESS_DATE.TXT.
This file get updated once the oracle partition created. In Oracle, Partition will be created every day. There is a seperate script scheduled to take care ORACLE partition creation.
The above file will have only one row. i.e
03092012
If Oracle partition creation job failed, the above file won't be updated.
My requirement is,
I have to check whether the BUSINESS_DATE file is updated today or not. If yes, I will have to move the files from common area to input file directory to process those files.
All file name will amend with current date.
i.e
LIDDIFD03092012.TXT
The key part is to check the BUSINESS_DATE.TXT file is updated properly or not.
We don't know what time the file will get updated. So we are planning to schedule the new script to run for every 15 mins to check whether the file is updated or not
But...I just thougt instead of writing a shell script to do the above one, Why shouldn't I capture the date in a table (New table needs to be created) and use ORACLE TRIGGER to run the shell script to move the files from common area to input file directory to process those files?
My Proposal in ORACLE :
Create table business_date
rep_date varchar(15),
curr_timestamp timestamp
Once the oracle partition created , one row will be inserted into the above table. This adjustment needs to be implemented partition script.
Once this table get record, TRIGGER should call SHELL SCRIPT to move the files from common area to input area.
If I implement ORACLE TRIGGER, The script which will check whether the file got updated or not for 15 mins is not required. Right? Inputs from experts are welcome!

Triggers should not be used to do transactional work. There is no COMMIT in a trigger. What happens if the trigger runs the shell script and then a ROLLBACK occurs? You will have run the shell script when it shouldn't run.
Create a stored procedure to run the shell script. Call the stored procedure when the partition is created.
If you were using 11g and interval paritioning you wouldn't need to create the partitions manually. Oracle could create the partitions automatically.

Pass in date from shell script to java program

Hi,
I need to pass in some parameter to my java program.
eg 'java SomeProgram yyyy mm dd hh mm ss'
How do i use the shell script to generate the valeus for the year, mth day etc?
The program is running once everyday.
I tried $argu0 = `date+%y`
java SomeProgram $argu0
but not working... thanks for your help!

Then, why would you want to use 'date' to provide
'now' to a Java program when you could just use new
java.util.Date() which probably makes the same call
as the Unix 'date' command?That works until you need to use a date other than 'now.'
    public static final String ISO_DATE = "yyyy-MM-dd HH:mm:ss";
    public static void main(String[] args) {
        SimpleDateFormat sdf = (SimpleDateFormat) SimpleDateFormat
                .getDateTimeInstance();
        sdf.applyPattern(ISO_DATE);
        try {
            Date d = sdf.parse(args[0]);
            // rest of code here
        } catch (ParseException e) {
            // handle exception
    }Users will have to enclose there input with quotes otherwise the JVM will consider their input as two parameters, or you can change the pattern to include a character between dd and HH.

You seem to have ignored Dude's VERY good advice and continue to press down this ill-advised path. If you continue this approach, you WILL have problems at the very time you do not need any additional problems. Trying to recover your production database at 2:00 in the morning is not the time to be getting errors from rman because it can't find what it needs - because you decided to move them around yourself.
Please reconsider.

Oracle 10g and Korn Shell Scripting

I have a table,SALES_STAGING, with 3 main columns.
Sales_Date, Sales_type,Sales_Code.
A sale is added to the table then waits until approved to be processed. The Sales_Code is 1(waiting approval). Then manually changed to 2 every 30 minutes by sales staff except on weekends. By Monday,a large queue develops. This must be changed because the queue is slowing the system. Can someone help create a Unix Korn shell script to
1) Run every 30 minutes via Crontab
2)login to the Oracle DB.
3)Count the number of records to be processed, if any.
4)Update another 'log' table with the time it ran and the records to be processed
5)if there are less than 20 add another 50 to be processed by changing the Sales_Code from 1 to 2.
This would really help out tremendously! Thank you.

Wait... Isn't this forum designed for the sharing of information? The experts here shouldn't be concerned whether the request is from a Student, Oracle newbie or Developer and should focus on the request. If you are capable of assisting then I am hoping you will out of the core respect for professionalism and the motivation to provide something of value to others. If not, don't waste my time or any one else by responding with preconceived judgments and insulting remarks as these will be reported.
Sales transactions can peak at 20,000 per hour with an average of several million thru the week. Those sales by VIP customers are immediately identified and have a priority for approvals because their balances can easily exceed $1,000,000.00. There is a pre-approval process to be introduced but until programs can be modified/tested and deployed we need a quick fix. The programming system isn't slow, it's the limited human resources approving VIP customers. My request was to keep it simple and expand on it myself to include the entire scope of our project. dbms_scheduler, although a good idea will require DBA assistance and there is no resource available. I need a simple working model to give me some direction/ideas...

Shell Script - Sleep

Hello All,
We are printing pdf file outputs from shell script. Here we faced a problem that the shell script tried to access the output file(pdf file) while the concurrent program is running. For that we added the concurrent program names into shell script programs incompatibility list. This is working fine.
But there are more than 20 reports using the same shell script. If all the programs are running shell script waits until all the 20 programs completed.
I am thinking of another solution that, I have to issue a sleep command in shell script until the program completes, or until the output file is generated and the shell script can generate post script file from the output file.
I dont know what kind of lock the concurrent program is using, because shell script says no such file or directory while generating post script file.
Kindly help.

You would probably find more concurrent manager experts in the Apps forums. You could try using the output of ps -ef to see if the program your script should wait for is still running. Or you can use the lsof command to see if the file you are supposed to process is still open in another process. For example, lsof -f -- /output/my.pdf shows all processes that have the file /output/my.pdf open.

Statspack report generation shell script?

Does anyone have a shell script (unix/solaris) which does the following:
Gets the snap_ids from the 09:00 and 17:00 statspack snapshots (from today or yesterday), and runs spreport.sql, using these snapshot ids as begin_snap and end_snap.
I do not want to purge any snapshots from the database. I simply want to generate a daily "9 to 5" statspack report every day.
TIA,
Dave

Hi,
You can do the following way:
1. Write script to get the begin snap_id as:
$cat > begin_snap.sql
set head off
set echo off
set verify off
set termout off
spool begin_snap_id.log
SELECT snap_id
FROM stats$snapshot
WHERE TRUNC(snap_time) = TRUNC(SYSDATE-1)
AND TO_NUMBER(TO_CHAR(snap_time,'HH24')) =9;
spool off
2. write a script to get end snap id as same as above substituting 9 with 17 with script name as end_snap.sql and spool file name as end_snap_id.log.
3. write a script to pass arguments for spreport.sql as:
cat > statspack_report
#!/bin/ksh
ORACLE_HOME=/home/oratest
TODAY=`date '+%Y%m%d' `
REPORT=report_${TODAY}.txt
sqlplus -s perfstat/perfstat@database_name @$ORACLE_HOME/begin_snap.sql <<EOF
EOF
BEGIN_ID=`cat /home/oratest/begin_snap_id.log | sed '/^$/d' `
sqlplus -s perfstat/perfstat@database_name @$ORACLE_HOME/end_snap.sql <<EOF
EOF
END_ID=`cat /home/oratest/end_snap_id.log | sed '/^$/d' `
sqlplus -s perfstat/perfstat@database_name @$ORACLE_HOME/rdbms/admin/spreport.sql <<EOF
${BEGIN_ID}
${END_ID}
${REPORT}
EOF
you can schedule this statspack_report in a crontab.
thanks

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.

Thanks,

Try this one by making following changes in crontab
file by 'crontab -e, command

Timer to generate on/off signal every 20 mins for 10 sec

I need to create a simple timer. It comes on every 20 minutes for 10 seconds, then switches off until another 20 minutes has passed, and so it repeats itself. I want to open a valve with this every 20 mins for 10 secs, then close it. This is to work with a field point device that we have on our shelves.

Here is a simple solution.
Create a while loop, inside the while loop put a sequence in step 1 place a wait vi and set the value to 20 min (remember this input is in ms so 20 min = 1200000) in step two place the code to send the on signal (hardware output I assume) in the third step of the sequence place another wait for 10 seconds (10000 ms) and finally place the off sequence last. This solution is very processor friendly. If you just compair time stamps inside a loop, the loop will be continiously checking the time and your CPU use will max out. You can place an inherent wait in the loop but the responsivness (accuracy of your timming) will be reduced. The wait statment will pause your program until the timer (I believe it is linked to the OS interupt system) expires. This solution allows for multiple threads (loops) to run cuncurrently with little extra overhead. I have used timers to generate alarms in the past where the sequence after the time expiring fires an occurance to drive code in other loops. Hope this helps
