Oracle Database Administration Scripts | DBA Bundle


Today I'm glad to share with you one of the most helpful tools I ever created to make the common database administration tasks faster, safer and more easier.

This tool I named it DBA Bundle , it's a tar file contains a group of most useful shell scripts that help the database administrator in day to day activities in a smart, safe and easy way, some of these scripts are old but still doing it's job efficiently :-)

Please DOWNLOAD the bundle from this link: [V. 1.8 29-Oct-2014]

You can watch this video tutorial on how to use this bundle: (watch this video in full screen mode)

The most greatest feature in this bundle that it can work on complicated environments to save the DBA time and reduce the human errors.

All scripts in this bundle can easily understand the environment whatever it's Linux or UNIX, most scripts can work fine on different database versions and different oracle homes and different oracle users owners on the same server, all scripts have been designed to smartly handle wrong user inputs.

Now let's get started with the main functions in this bundle ...

How to use the bundle:

First, download the bundle tar file and extract it under Oracle owner home directory, e.g. /home/oracle, please note that each script inside this bundle is independent, in other words, there is no script depend on another script in this bundle, the deletion of any script will not affect the successful execution of other scripts.

Second, I've created a script called "aliases_DBA_BUNDLE.shit will add an alias for each script inside the bundle to the user's profile to make it easy for you to call any script using one command "alias" from any working directory. This is not all, this script creates aliases to easily access the database configuration files and logs
alert     command alias will tail -f the ALERTLOG of the selected database|instance.
vialert  command alias will vi the ALERTLOG of the selected database|instance.
tns        command alias will open the tnsnames.ora file using vi editor
lis         command alias will open the listener.ora file using vi editor
There is still more of nice and easy shortcuts will be listed along with it's description after you execute ""script .
In order to keep this post abbreviated, I'll let you discover the rest of aliases yourself !

To call script "" use "." command: e.g.
#  .

What if I've more than one database on the server, how can I use  "" script?

Simple, let's say you've two databases running on the same server 
(SALESDB & ORCL), if you want to use the shortcuts (alert,tns,bdump,..) for SALESDB just run script "" and select SALESDB, later if you want to use the shortcuts (aliases) for ORCL DB re-run "aliases_DBA_BUNDLE.shscript then select ORCL, and so on.

Note: Each time you run "aliases_DBA_BUNDLE.shscript it will replace the aliases added in the last execution with new aliases referring to the database you selected.
running script "" more than once will not harm.

If you didn't manage to run "" 
script , each time you want to call a script you have to step under the location where you extracted the bundle then run the script you want.

Now let me give you a brief description of each script in the bundle:

Script Name        |  Description
-------------------|--------------------------------------------| Script to rebuild a table and its related indexes (New in V. 1.5)
-------------------|--------------------------------------------  | Script Export Full DB|SCHEMA|TABLE data

Scripts without an alias:
The following scripts doesn't have aliases because it's not applicable or need to be used carefully:
-------------------------------------------------------------------------------------------------------- | Script Monitors CPU utilization + Filesystem usage + ALERTLOGs of ALL Databases and
                     Listeners running on the server and instantly report ORA- errors and TNS- errors
                     that appears in these logs to the DBA E-mail Address
                     by sending an email to the DBA 
                     (you have to modify this parameter in line number 16 to point to your E-mail Address):

                      > Of course the sendmail service should be configured on the server.

                                  *The best use of this script is to schedule it's execution in the crontab 

                                    to run every 5 minutes (or less) to report ORA- and TNS- errors 
                                    when they appear in the DBs & listeners logs.
-------------------------|----------------------------------------------  | Script to SHUTDOWN ALL running Databases & Listeners on The server.
-------------------------|----------------------------------------------  | Script Takes a COLD BACKUP of a specific database 
                                         (It will also creates another script to help you restore the taken cold backup easily) 
                                         This script will shutdown the database, takes a cold backup, 
                                         creates a restore script (in case you want to restore this cold backup
                                         later ) then indeed it will startup the database.

That's all regarding this bundle, please note that time by time I'll update this bundle (adding new scripts, fixing bugs, adding new features). (This topic did not cover everything in this bundle).
