Easy and fast environment framework

Getting tired of typing and setting your ORACLE_HOME, ORACLE_SID and troubleshooting your . oraenv ?
going/connecting to different client sites with different platforms and server environments sometimes it is frustrating just how long it takes to get a proper SQL*Plus environment

So I always make use of this script
http://karlarao.tiddlyspot.com/#%5B%5Bstep%20by%20step%20environment%5D%5D

and for every server that I access I just have to do three bits of typing:

. ~oracle/.karlenv <<– set the environment
2 <<– choose an instance
s <<– rlwrap'd sqlplus alias

see example usage below:

[root@desktopserver ~]# su - oracle
[oracle@desktopserver ~]$
[oracle@desktopserver ~]$ vi .karlenv      <-- copy the script from the "Install environment framework - karlenv" section of the wiki link above
[oracle@desktopserver ~]$
[oracle@desktopserver ~]$ ls -la | grep karl
-rw-r--r--  1 oracle dba   6071 Dec 14 15:58 .karlenv
[oracle@desktopserver ~]$
[oracle@desktopserver ~]$ . ~oracle/.karlenv      <-- set the environment
<HOME_LIST>
<HOME NAME="Ora11g_gridinfrahome1" LOC="/u01/app/11.2.0/grid" TYPE="O" IDX="1" CRS="true"/>
<HOME NAME="OraDb11g_home1" LOC="/u01/app/oracle/product/11.2.0/dbhome_1" TYPE="O" IDX="2"/>
</HOME_LIST>
<COMPOSITEHOME_LIST>
</COMPOSITEHOME_LIST>


 1-       +ASM
 2-         dw

Select the Oracle SID with given number [1]:
2      <-- choose an instance
Your profile configured for dw with information below:
The Oracle base has been set to /u01/app/oracle

ORACLE_SID=dw
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1

oracle@desktopserver.local:/home/oracle:dw
$ s      <-- rlwrap'd sqlplus alias, also you can use the "s1" alias if you don't have rlwrap installed

BTW, parts of the code came from this blog by Coskan Gundogar http://goo.gl/cqRPK and I’ve edited/added some lines on the setsid and showsid sections making it suitable for most unix(solaris,aix)/linux environments

Also I’ve added lines of code before and after the setsid and showsid to get the following info:

• software homes installed

– very useful on troubleshooting if you have multiple homes (RDBMS/Grid Infra/EMGC)

• get DBA scripts location

– quickly plugin your script folders by editing the “# SCRIPTS LOCATION” section

• set alias

– quickly add alias by editing the “# ALIAS” section

Hope I’ve shared you some good stuff!
