Script to Generate Grant in Database

Posted on by Osama Mustafa in Scripts
Sometime when you want to create test environment you need to sure it will Identical and make sure grant are the same .

the below scripts include all grants made by user.
P.S :

  • For non-Windows platforms, change the second-last line, “host notepad”, to call your favorite text editor instead. 
  • You will need to input a list of users.
  • If you don’t know the passwords of some of the users, wait until they’re not logged on, copy their encrypted passwords from dba_users, reset their passwords to a temporary value, run the generated script, and then reset their passwords to their original values using alter user … identified by values ‘…’
  • Before you run the generated script, you need to know the passwords of all the users who will be making grants. Search the generated script for “connect” to figure out who this is. 

I upload the scripts as grant.sql

Enjoy

Script to Restart the OEM Agent When It Has Failed

Posted on by Osama Mustafa in Scripts
Gaurav Batta has published this nice script to restart the OEM agent when it has failed:

$ cat agent_check.sh
#!/usr/bin/ksh
#
agent_status=`ps -ef|awk ‘{print $8}’|grep agent10g/bin/emagent`

if [[ -z $agent_status ]]
then
$AGENT_HOME/bin/emctl start agent
echo Agent started on server `hostname` at `date`
else
echo Agent is running fine on server `hostname` at `date`
fi

It is running every 30min.
crontab –l

00,30 * * * * /home/oemagent/agent_check.sh >> /home/oemagent/agent_status.log




Enjoy 


Thank you

---------- -------------------- ---------- ----------
 10005 palani                             54544         10
 10001 Scott Tiger                     1000           40
 10002 Frank Naude                 500             20
 10003 rajesh                            21000         140
 10004 ramesh                           3500          220
 10005 suresh                            34567        123
 
 

delete duplicate rows in empid column in emp table 

 
 

 SQL>delete from emp where rowid not in (select max(rowid) from emp group by empid);


1 row deleted.

SQL>select * from emp;


 EMPID ENAME                       SAL     DEPTNO
---------- -------------------- ---------- ----------
 10001 Scott Tiger                       1000         40
 10002 Frank Naude                   500           20
 10003 rajesh                             21000        140
 10004 ramesh                           3500           220
 10005 suresh                            34567        123
 
 
to delete the old duplicate row from the table instead of max(rowid) replace min(rowid) 
for exampl
 

SQL>insert into emp values(10005,’Osama’,54544,10);


1 row created.

SQL>select * from emp;


   EMPID ENAME                       SAL     DEPTNO
---------- -------------------- ---------- ----------
   10005 Osama                           54544        10

Check who Use the same record you want to delete

Posted on by Osama Mustafa in Scripts
Just Run the Below Script and after this kill the session :

  select owner||’.’||object_name obj
 ,oracle_username||’ (‘||s.status||’)’ oruser
 ,os_user_name osuser
 ,machine computer
 ,l.process unix
 ,’||s.sid||’,’||s.serial#||’ ss
 ,r.name rs
 ,to_char(s.logon_time,’yyyy/mm/dd hh24:mi:ss’) time
 from       v$locked_object l
 ,dba_objects o
 ,v$session s
 ,v$transaction t
 ,v$rollname r
 where l.object_id = o.object_id
and s.sid=l.session_id
and s.taddr=t.addr
and t.xidusn=r.usn
order by osuser, ss, obj ;

To kill the session : 

Alter System kill Session ‘Sid,Serail#’ immediate ;

Check Your Database Size

Posted on by Osama Mustafa in Scripts
Datafiles : 

select sum(bytes)/1048576 “DATAFILES_SIZE_MB” from dba_data_files;

Tempfiles:

select sum(bytes)/1048576 “TEMPFILES_SIZE_MB” from dba_temp_files;

Your redo logs can also use up a large amount of disk space – especially if your database has more than the minimum number of 2 redo log groups. (You may also have several members within each group).

Redologs:

select sum(bytes)/1048576 “REDOLOGS_SIZE_MB” from v$log;

The database obviously needs controlfiles to record information such as which datafiles belong to the database.  If your CONTROL_FILE_RECORD_KEEP_TIME is set to a large value, then your controlfiles can become quite large.

Controlfiles:


select round(sum(block_size*file_size_blks)/1048576,2) “CONTROLFILESIZE_MB” from v$controlfile;

From 10g onwards, flashback database is not enabled by default, but if it is, then this area can grow rapidly over time.

Flash Recovery Area:


select * from v$recovery_file_dest; 
select * from v$flash_recovery_area_usage;  

These views will show sizing details and free space available.

Note: If your backups are held outside of the flash recovery area, then you’ll also need to allow space for these. This will depend on your backup strategy and backup retention policy. (Export/datapump export dumpfiles also need to be planned for).
If you are using RMAN incremental backups and have block change tracking enabled, then include this file:

Block change tracking file


select filename, nvl(bytes/1048576,0) “BLOCK_CT_SIZE_MB” from v$block_change_tracking;

Files referenced by database directories or the utl_file_dir parameter:


Your application may read from, or write to external files via database directories or the utl_file_dir parameter.

Other examples of using external directories are for

(a) External tables –

select a.owner||’.’||a.table_name||’ stored in directory ‘||b.directory_path “EXTERNAL_TABLES”
from dba_external_locations a, dba_directories b
where a.directory_owner=b.owner
and a.directory_name=b.directory_name;

(b) If you are storing multiple versions of the same tablespace within a file group repository. (i.e. tablespace versioning).

select a.tablespace_name, a.version, a.file_group_owner, a.file_group_name,
b.file_name, b.file_directory
from dba_file_group_tablespaces a, dba_file_group_files b
where a.file_group_owner=b.file_group_owner
and a.file_group_name=b.file_group_name;

Scripts For Backup

Posted on by Osama Mustafa in Scripts
This Script Will Let you choose One Of three Type Of backup , All you have to do right the backup scripts to make the below script read it and run it :

#!/bin/bash
ORACLE_SID=ORCL;export ORACLE_SID
echo $ORACLE_SID
echo “Please Specify the kind of backup you want to take”
echo “1) COLD BACKUP”
echo “2) HOT BACKUP”
echo “3) EXPORT BACKUP”
echo “Enter your option”
read option
 while [ $option -gt 3 ]||[ $option -le 0 ]
do
echo “Please Enter the correct option”
read option
done
case $option in
1|2) echo “You are taking rman backup of DB”
   rman target sys/sys @/oracle/product/11g/rman_backup_$option.txt;exit;;
3) echo “You are taking export backup of DB”
   exp system/sys file=/oracle/exp_dat.dmp log=/oracle/exp_dat.log full=y;
   exit;;
esac
exit

 The above script can call anyone of the following rman script depending upon the user who wants take cold or hot backup

The content of rman_backup_1.txt

run {
   shutdown immediate;
   startup mount;
   allocate channel dup1 device type disk;
   allocate channel dup2 device type disk;
   backup format ‘/oracle/%U’ database;
   release channel dup1;
   release channel dup2;
   alter database open;
  }

The content of rman_backup_2.txt

run {
allocate channel dup1 device type disk;
allocate channel dup2 device type disk;
backup format ‘/oracle/%U’ database;
backup format ‘/oracle/arch_%U’ archivelog all;
backup format ‘/oracle/ctl_%U’ current controlfile;
release channel dup1;
release channel dup2;
}

Check RMAN Backup Status

Posted on by Osama Mustafa in Scripts
The Below Scripts To Check Backup Status Via Sqlplus , Maybe you will find Same Or Another Scripts In the Same way : 

Sqlplus / as sysdba

This script will report on all backups – full, incremental and archivelog backups –

col STATUS format a9
col hrs format 999.99
select
SESSION_KEY, INPUT_TYPE, STATUS,
to_char(START_TIME,'mm/dd/yy hh24:mi') start_time,
to_char(END_TIME,'mm/dd/yy hh24:mi')   end_time,
elapsed_seconds/3600                   hrs
from V$RMAN_BACKUP_JOB_DETAILS
order by session_key;
 

This script will report all on full and incremental backups, not archivelog backups –

col STATUS format a9
col hrs format 999.99
select
SESSION_KEY, INPUT_TYPE, STATUS,
to_char(START_TIME,'mm/dd/yy hh24:mi') start_time,
to_char(END_TIME,'mm/dd/yy hh24:mi')   end_time,
elapsed_seconds/3600                   hrs
from V$RMAN_BACKUP_JOB_DETAILS
where input_type='DB INCR'
order by session_key;

I would Love to Thank gavin soorma – OCM For His Amazing Effort . Share it For Knowledge .

Thank you

Working with RMAN Stored Scripts

Posted on by Osama Mustafa in Scripts

Creating Stored Scripts: CREATE SCRIPT

 

Make sure RMAN is connected to the right target database and the recovery catalog. Then run the CREATE SCRIPT command, as shown in this example: 

 
 
CREATE SCRIPT full_backup 
{     
  BACKUP DATABASE PLUS ARCHIVELOG;
  DELETE OBSOLETE;
} 
 
 

 you can also provide a COMMENT with descriptive information:

CREATE GLOBAL SCRIPT global_full_backup 
COMMENT 'use only with ARCHIVELOG mode databases'
{     
  BACKUP DATABASE PLUS ARCHIVELOG;
  DELETE OBSOLETE;
}

Running Stored Scripts: EXECUTE SCRIPT

 

RUN { EXECUTE SCRIPT full_backup; }

Displaying a Stored Script: PRINT SCRIPT

PRINT SCRIPT full_backup;
PRINT SCRIPT full_backup TO FILE 'my_backup.txt';

Listing Stored Scripts: LIST SCRIPT NAMES

LIST SCRIPT NAMES;

LIST ALL SCRIPT NAMES;

Updating Stored Scripts: REPLACE SCRIPT

REPLACE SCRIPT full_backup 
{
  BACKUP DATABASE PLUS ARCHIVELOG;
}

Deleting Stored Scripts: DELETE SCRIPT

  

DELETE SCRIPT 'full_backup';
DELETE GLOBAL SCRIPT 'global_full_backup';

 

 

 

 Thank you
