Shell script for exp
Hello All,
OS: AIX 5.2
we are doing full export of our database schema as below:
exp
username:schema name
Enter array fetch buffer size: 4096 >Export file: expdat.dmp > exp020806v1.dmp
(2)U(sers), or (3)T(ables): (2)U > U
Export grants (yes/no): yes > yes
Export table data (yes/no): yes > yes
Compress extents (yes/no): yes > yes
Export done in US7ASCII character set and AL16UTF16 NCHAR character set
Export terminated successfully without warnings.
Now I want this all be done by shell script.
user logon as a abc.
he will get menu options
1. full database export
user will select this option (1 by enter type 1) and enter and it will do exp for this particular schema.

Below you'll find an Korn-shell export script that works on AIX 4.3.3; it'll work on
AIX 5.3 as well. It creates a compressed full exportfile by exporting to a named pipe and feeding the output to compress. Because export is a client tool, the scripts first established the NLS characterset of the database and exports it into
the NLS_LANG variable.
You'll need to customize the script, e.g. set your own directory names etc.
The script can be run from cron
#!/usr/bin/ksh
# 26-10-2004 - Hans Wijte
function get_characterset
{ sqlplus -s / << !
set feedback off
set heading off
select value
from v\$nls_parameters
where parameter = 'NLS_CHARACTERSET';
if [[ -z ${ORACLE_HOME} ]]
then
. $HOME/.profile 1>/dev/null 2>&1
fi
export ORACLE_SID=${1:-$ORACLE_SID}
export_dir=${2:-/oracle/exports/$ORACLE_SID}
export ORAENV_ASK=NO
. oraenv
export ORAENV_ASK=YES
export NLS_LANG="."`get_characterset`
# Set the necessary Oracle variables #
export ORACLE_SID=$1
ORAENV_ASK=NO
. oraenv
id=$$
# Create a named pipe to export to #
PARFILE=exp_${ORACLE_SID}_exp_tables.par
mknod oraexp${id}.pipe p
touch ${PARFILE}
chmod 600 ${PARFILE}
# Fill the parameter file with #
# the desired parameters #
tabs=`cat tabs.log`
echo "
userid = /
buffer = 1024000
log = /oracle/home/log/exp_${ORACLE_SID}_exp_tables.log
file = /oracle/exports/${ORACLE_SID}/exp_${ORACLE_SID}_exp_tables.dmp.Z
full = yes
consistent = y
compress = n
" > exp_${ORACLE_SID}_exp_tables.par
# Point the named pipe to the dumpfile and #
# let compress receive the output from #
# the named pipe #
compress < oraexp${id}.pipe > exp_${ORACLE_SID}_exp_tables.dmp.Z &
# Execute the EXPORT utility with #
# the parfile just created #
exp parfile= exp_${ORACLE_SID}_exp_tables.par
# Sync the file systems #
sync; sync; sync
rm -f oraexp${id}.pipe
rm -f ${PARFILE}

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.

Shell script for archive log transfer
hi
I dont want to reinvent the wheel.
I am looking for shell script for log shipping to provide standby db.
What I want to do is, get the last applied archived log number from alert.log
Copy the files from archive destination according to this value.
CheersIf you don't want to re-invent the wheel you use Dataguard, no scripts.
And your script should use the dictionary, instead of some bs method to read the alert.
v$archived_log has all information!
Also as far as I know, the documentation describes manual standby.
So apparently you not only don't want to reinvent the wheel, but you want the script on a silver plate on your doorstep!
Typical attitude of most DBAs here. Use OTN for a permanent vacation.

What are you trying to do exactly?
It's working but you have to put it in a loop. Fine, what's the problem you are having?
begin
loop
exit when ... whatever the exit condition is ...

Shell script for export backup in oracle 11g
Hi,
Oracle version 11.2.0..
O/S-AIX
How to write shell script for export full backup in oracle 11g and also need to remove 2 days of old backup.
Regards,
RajuHow to write shell script for export full backup in oracle 11g
Do you mean that export is your backup strategy ? is your database running in noarchivelog mode ? if so, then why ? if not so, then why not RMAN ?
need to remove 2 days of old backup.
If that mean remove files older than 2 days, you can use something like this :
$ find <absolute directory path> -mtime +2 -exec rm {} \; -

Hi,
I have written shell script for below scenarios, can you please guide me to write this as correct way, requirment is,
1. i need to connect the database which is on unix server , but before connecting the DB some of the files needs to be removed from \tmp directory.
2. once removed the script need to connect the database and call the sql file which is in \tmp directory.
3. the output files will be stored in \tmp directory start with DB name.
4. finally csv files needs to be transferred to local windows with help of FTP. please find below the script
#!/bin/sh
rm -f /tmp/dbmon/DB1*
CONNSTRING=username/PASSWORD@service
sqlplus -s $CONNSTRING @/tmp/STATS.sql << EOF
EXIT;
EOF
HOST='xxxxx'
USER='xxxxx'
PASSWD='xxxxxx'
FILE='E:\STATS\DB1.*'
cd /tmp/dbmon
ftp -n -v $HOST << EOT
user $USER $PASSWD
prompt
mput $FILE
bye
EOT
EXIT;
EOF
Thanks
Edited by: ASP on Nov 18, 2011 4:45 PMHi ASP
It's always a good idea to write entries to timestamped log file without which you will never know where the script went wrong or failed.
This is not tested but just a small example
#!/bin/sh
export LOG_DIR=/tmp/log
export LOGFILE=$LOG_DIR/`basename $0`_${TIMESTAMP}.log
if [ ! -d $LOG_DIR ]
then
mkdir $LOG_DIR
fi
echo "Removing the temporary files from /tmp/dbmon at `date +%Y%m%d_%H:%M:%S`" | tee -a $LOG_FILE
rm -f /tmp/dbmon/DB1*
CONNSTRING=username/PASSWORD@service
echo "Run SQLPlus file" | tee -a $LOG_FILE
sqlplus -s $CONNSTRING @/tmp/STATS.sql << EOF
EXIT;
EOF
echo "Now FTP the files to windows box " | tee -a $LOG_FILE
HOST='xxxxx'
USER='xxxxx'
PASSWD='xxxxxx'
cd /tmp/dbmon
ftp -vn $HOST <<EOF
quote USER $USER
quote PASS $PASSWD

cd E:\STATS
mput DB1.*

Shell Script for Startup and Shutdown the database
Hi,
i want Shell Script for Startup and Shutdown the database in Solaries.

Thanks & Regards,
Gangi reddySHUTDOWN
SHUTDOWN ABORT]
Shuts down a currently running Oracle instance, optionally closing and dismounting a database.
Terms
Refer to the following list for a description of each term or clause:
ABORT
Proceeds with the fastest possible shutdown of the database without waiting for calls to complete or users to disconnect.
Uncommitted transactions are not rolled back. Client SQL statements currently being processed are terminated. All users currently connected to the database are implicitly disconnected and the next database startup will require instance recovery.
You must use this option if a background process terminates abnormally.
IMMEDIATE
Does not wait for current calls to complete or users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
NORMAL
NORMAL is the default option which waits for users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
TRANSACTIONAL [LOCAL]
Performs a planned shutdown of an instance while allowing active transactions to complete first. It prevents clients from losing work without requiring all users to log off.
No client can start a new transaction on this instance. Attempting to start a new transaction results in disconnection. After completion of all transactions, any client still connected to the instance is disconnected. Now the instance shuts down just as it would if a SHUTDOWN IMMEDIATE statement was submitted. The next startup of the database will not require any instance recovery procedures.
The LOCAL mode specifies a transactional shutdown on the local instance only, so that it only waits on local transactions to complete, not all transactions. This is useful, for example, for scheduled outage maintenance.
Usage
SHUTDOWN with no arguments is equivalent to SHUTDOWN NORMAL.
You must be connected to a database as SYSOPER, or SYSDBA. You cannot connect via a multi-threaded server. For more information about connecting to a database, see the CONNECT command earlier in this chapter.

Apologees for the c!=k!=b stuff. I guess it was to cryptic. It means

About shell scripts for large-scale automation of encoding tasks
in the user menu of Compressor, it said that we can use the command line to write shell scripts for large-scale automation of encoding tasks.
I would like to have more information about the shell script for compressor, is that any document link?
ThanksYou can use a script function to set-up a more secure environment that you call at the start of every admin script. This could be your main stamp album for stuff that can be moved there.
A few more stamps to add to the collection (be sure to read up on them before use):
1) reset the command hash
hash -r
2) prevent core dumps
ulimit -H -c0
3) set the IFS
4) clear all aliases (see unalias -a)
Also you can remove the ALL from sudo and add explicit commands to the the sudoers file. There's a lot of fine tuning you can do in sudoers - inc. env variables as teekay said.
But I'm no expert so best to check all of the above. -

Shell scripting for oracle DBs
looking for good source for shell scripting for oracle DBs
Just buy 'Classic Shell Scripting' and 'the Unix Desktop Reference' both published by O'Reilly and you have it all.
But if you want a platform agnostic scripting language use Perl. Comes with Oracle.
