What is the best way to deploy an application ??

Question

Hi,
Please advise me how to automate in a best way to Deploy 10 different applications(.ear/.war)
to 10 different Clusters(containing 40 Managed servers) in wls6.1......and that
too in a Production environment.
I know that we can use weblogic Console to deploy an application BUT if i have
2 unix boxes and each box contains 4-4 clusters(each containing 16-20 managed
servers) .....then i have to open up 2 Admin server consoles to deploy each of
the respective applications and that too deploying these application to 8 clusters.....OR
i can use deploy commad to do the same.
AND if i have like 100 clusters .....then i would have to "deploy" 100 times ......
is there any way that we can BEST AUTOMATE this process.
Thanks a lot.

Answer 1

Thanks Tommy. but i would like to know a very important point here: this is using
the weblogic.utility that you just talkd about.
Suppose iam having an ADMIN server that has say 10 clusters and 50 managed servers
underneath to take care.
1 cluster each = 5 managed server
now iam deploying a simple .war file to say a single managed server, i have found
out that it takes a looot of time to get the application deployed.
what do you say about this situation ?
what is the best approach ??????

To deploy the application from the command prompt in WebLogic 6.1 you
use the
following command
$JAVA_HOME/bin/java -cp $WL_HOME/weblogic.jar weblogic.deploy -port $WEBLOGIC_PORT
-host $WL_HOST_IP $WEBLOGIC_CMD $WEBLOGIC_PWD -component $WL_Server_NAME:$WL_Server_NAME
$WL_APPLICATION_NAME YourApplication.war
$WEBLOGIC_CMD sould be DEPLOY for the first time deployment and UPDATE
for redeployment
For deploying in a cluster you better create a shell script which call
the above
command with different cluster ip address as a parameter.

Thanks Rob for your expertise advise. I would check to see wls8.1's
ANT tasks.....for
wls6.1, i would guess shell scripts to be a better option for us.
thanks again.

If you're using 8.1, then it's pretty nice to use ant for
configuration/deployment/starting and stopping servers etc. There's
a
wlconfig task to do configuration, wldeploy to deploy applications,
wlserver to start/stop servers.
For 6.1, it's probably not a huge win to use ant. It's up to you.
If
you're more comfortable using shell scripts, that's certainly a
reasonable route.

But all the stuff that ANT can do for me FOR DEPLOYMENT (ONLY) .....ican do it
from a simple shell script too.
And i understand of ANT's cross-platform environment and usage of
JAVA
.....but
can i use ANT to do something like CONFIGURING my wls6.1 managed
servers/clusters/creating
managed servers/db connection pools ......and all the other configurationthat
i do from wls console(or manually) ....????
and if yes, do you know of any examples, suggestions, ideas ?????
basically, if i need to sell(?) ANT to my juniors ......what are
the
basic reasoning
i can put forward....keeping in mind that these guys use wls6.1 &
wls8.1......and
these guys do CONFIGURATION and DEPLOYMENT only.
sorry for asking, may be these silly questions.
thanks, sangita

Rob, do you still consider or suggest using ANT for deploying say
20
applications
on a 10 clustered environment.Yes
do you see any advantages using [ANT + weblogic.deploy]..... over
simply
using
weblogic.deploy utility ???Yes. ANT essentially gives you a cross-platform environment that
allows
extensibility through java. It's very powerful.

Rob,
I have found the answer for my question #1 ...this is the URL:
http://edocs.bea.com/wls/docs81/admin_ref/ant_tasks.html
iam still hoping to hear back from you for #2, #3
thanks a ton.

quick question:
1) do you know of any example which illustrates the use of ANT
wrapper....or
please
direct me to a URL where i can find some documentation about
it.
2) does this ANT wrapper has any advantages over using weblogic.Deployer
utility
??If you're doing deployment via ant, then it's a bit more convenientto
use <wldeploy> rather than invoking a raw <java> process, but
fundamentally it's just a wrapper around weblogic.Deployer
3) i would certainly check to see weblogic.deploy for wls6.1
....can
i use ANT
for deployment purpose in wls6.1 ?You'll just need to wrap it in a <java> task
See:
http://ant.apache.org/manual/CoreTasks/java.html

If you were using WLS 7.0 or later, you could use weblogic.Deployer.
If
you were using 8.1, you could use wldeploy which is an ant task
wrapper
for weblogic.Deployer.
In WLS 6.1, you'll have to use weblogic.deploy which is a bit
cumbersome, but it's still certainly possible to script deployment.
