Introduction:
In this post, I’ll share with you one of the most helpful tools I ever created, it will make database administration day to day activities more easier, faster and safer for you.
I named it DBA Bundle , it’s a tar file contains a group of shell scripts, you can DOWNLOAD the latest version from this link:[V. 4.0 07-Jan-2018]
https://www.dropbox.com/s/xn0tf2pfeq04koi/DBA_BUNDLE4.tar?dl=0
I’ve designed all scripts to be able to run on complicated environments, whereas there is one or more Oracle version / Oracle Home installed on the same machine.
All scripts inside the bundle can easily recognize the Oracle environment whether it’s a Linux or Unix a long with databases version, Oracle homes.
All scripts can smartly handle user’s wrong inputs as well.
Now let’s get started with the top key features 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, each script inside this bundle is independent, in other words, the absence of any script will not affect the execution of other scripts.
Second, from the bundle extracted directory, run “aliases_DBA_BUNDLE.sh” script using “.” command e.g. . aliases_DBA_BUNDLE.sh
It will add an alias for each script to the user’s profile to make it easy for you to call any script from OS shell under any working directory using one command “alias” without the need to step under the bundle directory.
Aliases will be displayed to you a long with its description in a tabular format. no need to memorize it, in case you want to list it again just type “bundle” command.
Please note that when you run any interactive script in this bundle it will prompt you to select the database number from the displayed list in case you have more than one up & running database.
For a script like “aliases_DBA_BUNDLE.sh” when you select a database from the list, aliases like “alert, tns, bdump,…” will automatically point to the respective files to the database you have chosen from the list.
e.g. if you have two running instances (orcl & salesdb), and you want to open the alertlog of salesdb, just run “aliases_DBA_BUNDLE.sh” scripts, enter salesdb number from the displayed list, and then type alert/vialert to view salesdb alertlog files.
If you didn’t run “aliases_DBA_BUNDLE.sh” script, for each time you want to call a script, you will need to step under the bundle location and then execute the script from there.

(you have to modify this parameter in line number 27 to point to your E-mail Address): MAIL_LIST=”youremail@yourcompany.com” > For sure sendmail service should be configured on the server. *The best way to use this script is by schedule it to run in the crontab every 5 minutes (or less) to report ORA- and TNS- errors when they written to alertlog & listeners logs.

From time to time I’ll keep updating this bundle with new scripts, fixing bugs and adding new features, so give this topic a visit at least once every 3 months to download the latest version.
As I mentioned in each script, I’M SHARING THIS BUNDLE AND ITS SCRIPTS IN THE HOPE THAT IT WILL BE USEFUL FOR YOU, BUT WITHOUT ANY WARRANTY. ALL SCRIPTS IN THIS BUNDLE ARE PROVIDED “AS IS”.
No one is perfect… that’s why pencils have erasers.
