I am looking for a shellscript to stop and start all nodes in the WebSphere cluster.
We have a deploy script for deploying on WAS servers , now we want to edit this script to stop the WAS servers before the deployment and starts after the deployment . we dont have scope to edit the existing script (which is only readable to me) , they asked to create start/stop scripts separate so that they can invoke this before and after deployment.
Will the below commands suffice to incorporate with the main deploy script.
start: $WAS_HOME/bin/startServer
stop: $WAS_HOME/bin/stopServer
Any help would be appreciated.
P.S - Let me know if you need the original deploy script
Thanks
The best option would be to use wsadmin command line interface. Which can be invoked using a shell.
If you need to use a shell script to do this, typically you would invoke the WebSphere wsadmin command from the shell and use the -f option to specify a Jython or Jacl script that performs the desired actions. In that script you'll use the AdminControl object to stop and start clusters. See this IBM KnowledgeCenter topic for details. More general information about controlling clusters, nodes, servers with scripting can be found in this KC topic .

I have a .sh script in Google Cloud Shell that automates my instance shutdown, backup, restart sequence.
How can I run a .sh script on Schedule (i.e. daily) in a simplest possible way?
I am not a professional and I've read all documentation about cron jobs, Cloud Scheduler, Cloud Tasks... but none of the examples in the documentation appear to detail a simple task that I need, and I do not have enough knowledge yet to understand these multiple services in details.... I just need a simple direction pointer to understand how to connect my Google Cloud Shell .sh script with any form of scheduler, as in:
Run a .sh script that I have in my virtual 5gb Cloud Sell Storage on schedule (daily at specific time), instead of manually opening Google Cloud Console and using a terminal to run the same script with "bash" command?
I just need to know what I need to learn/do to make this happen.
Thank you for your input.
That's not going to be possible. The Cloud Shell will turn off shortly after you close the tab. For this you'll need to use an actual VM. You can run one for free using the e2 micro instance.

Once you got this setup you can learn crontab to run your script on a schedule.
While running the Java EE Batch job through eclipse, it is creating a new instance of it.
I wanted to re-run the failed instance so that it can use checkpoint information to resume from the failed point.
Step 1: Deploy Application into Liberty server.
Step 2: Run the batchManger.bat file from cmd, which can find under bin folder of your local server
.\batchManager.bat restart --batchManager=localhost:9443 --user=admin --password=P#ssw0rd --applicationName=your-app-Name --jobXMLName=XXXX.xml --wait --trustSslCertificates
Another (GUI) approach is to use the Admin Center Java Batch tool, which allows you to restart jobs submitted by other methods. You can reuse, and/or modify the original job execution parameters.
This also provides a rich set of search and filtering capabilities, plus lets you view job logs, and so complements the job submission capability in the Eclipse Java EE Batch tooling.
Start here for complete instructions on using Admin Center. In particular you need to make sure the adminCenter-1.0 feature is installed then configure a userid to be authorized as the administrator.
Then, as the Java Batch tool instructions say, configure your server.xml with features:
adminCenter-1.0
batchManagement-1.0
I have a .sh file that is stored in GCS. I am trying to schedule the .sh file through google cloud shell.
I can run the same file using gsutil cat gs://miptestauto/baby.sh | sh command but not able to schedule it.
Following is my code for scheduling the file:
16 17 * * * gsutil cat gs://miptestauto/baby.sh | sh
It displays the message as "auto saving..done" but the scheduled job is not get displayed when I use crontab -l
# contents of .sh file
bin/bash
bq load --source_format=CSV babynames.baby_destination13 gs://testauto/yob2010.txt name:string,gender:string,count:integer
Please can anyone tell me how schedule it using google cloud shell.
I am not using compute engine/app engine. Just wanted to schedule it using the cloud shell.
thank you in advance :)
As per the documentation, Cloud Shell is intended for interactive use only. The Cloud Shell instances are provisioned on a per-user, per-session basis and sessions are terminated after an hour of inactivity.
In order to schedule a daily cron job, the instance needs to be up and running all time but this doesn’t happen with Cloud Shell and I believe your jobs are not running because of this.
When you start Cloud Shell, it provisions a f1-micro instance which is the same machine type you can get for free if you are eligible for “Always Free”. Therefore you can create a f1-micro instance, configure the cron job on it and leave it running so it can execute the daily job.
You can check free usage limits at https://cloud.google.com/compute/pricing#freeusage
You can also use the Cloud Scheduler product https://cloud.google.com/scheduler which is a serverless managed Cron like scheduler.
To schedule a script you first have to create a project if you don’t have one. I assume you already have a project so if that’s the case just create the instance that you want for scheduling this script.
To create the new instance:
At the Google Cloud Platform Console click on Products & Services which is the icon with the four bars at the top left hand corner.
On the menu go to the Compute section and hover on Compute Engine and then click on VM Instances.
Go to the menu bar above the instance section and there you will see a Create Instance button. Click it and fill in the configuration values that you want your new instance to have. The values that you select will determine your VM instance features. You can choose, among other values, the name, zone and machine type for your new instance.
In the Machine type section click the drop-down menu tab to select an “f1-micro instance”.
In the Identity and API access section, give access scope to the Storage API so that you can read and write to your bucket in case you need to do so; the default access scope only allows you to read. Also enable BigQuery API.
Once you have the instance created and access to the bucket, just create your cron job inside your new instance: In the user account under which the cron job will execute, run crontab -e and edit this file to run the cron job that will execute your baby.sh script.The following documentation link should help you with this.
Please note, if you want to view output from your script you may need to redirect it to your current terminal.
Until we can implement our new HEAT SM system i am needing to create some workflows to ease our currently manual user administration processes.
I intend to use Powershell to execute the actual tasks but need to use VBS to send an argument to PS from an app.
My main question on this project is, Can an argument be sent to an already running Powershell process?
Example:
We have a PS menu app that we will launch in the AM and leave running all day.
I would love for there to be a way to allow PS to listen for commands/args and take action on them as they come in.
The reason I am wanting to do it this way is because one of the tasks needs to disable exchange features and the script will need to establish a connection a remote PSsession which, in our environment, can take between 10-45 seconds. If i were to invoke the command directly from HEAT (call-logging software) it would lock up while also preventing the tech from moving on to another case until the script terminates.
I have searched all over for similar functionality but i fear that this is not possible with PS.
Any suggestions?
I had already setup a script to follow this recommendation but i was curious to see if there was a more seamless approach
As suggested by one of the comments by #Tony Hinkle
I would have the PS script watch for a file, and then have the VBScript script create a file with the arguments. You would either need to start it on another thread (since the menu is waiting for user input), or just use a separate script that in turn starts another instance of the existing PS script with a param used to specify the needed action
I want to deploy to all four processes on a Websphere cluster with two nodes. Is there a way of doing this with one Jython command or do I have to call 'AdminControl.invoke' on each one?
Easiest way to install an application using wsadmin is with AdminApp and not AdminControl.
I suggest you download wsadminlib.py (Got the link from here)
it has a lot of functions, one of them is installApplication which works also with cluster.
Edit:
Lately I found out about AdminApplication which is a script library included in WAS 7 (/opt/IBM/WebSphere/AppServer/scriptLibraries/application/V70)
The docuemntation is not great in the info center but its a .py file you can look inside to see what it does.
It is imported automatically to wsadmin and you can use it without any imports or other configuration.
Worth a check.
#aviram-segal is right, wsadminlib is really helpful for this.
I use the following syntax:
arg = ["-reloadEnabled", "-reloadInterval '0'", "-cell "+self.cellName, "-node "+self.nodeName, "-server '"+ self.serverName+"'", "-appname "+ name, '-MapWebModToVH',[['.*', '.*', self.virtualHost]]]
AdminApp.install(path, arg)
Where path is the location of your EAR/WAR file.
