Im trying to call a command from wsadminlib.py to change the initialHeapSize and the maximumHeapSize in a script. But unfortunately my jython (and general scripting knowledge) is still total newbie.
Im using the call
#Change Java Heap Size
setJvmProperty(nodeName,serverName,maximumHeapsize -2048 ,initialHeapSize -2048)
Which should relate to the command in the wsadminlib.py library
def setJvmProperty(nodename,servername,propertyname,value):
"""Set a particular JVM property for the named server
Some useful examples:
'maximumHeapSize': 512 ,
'initialHeapSize':512,
'verboseModeGarbageCollection':"true",
'genericJvmArguments':"-Xgcpolicy:gencon -Xdump:heap:events=user -Xgc:noAdaptiveTenure,tenureAge=8,stdGlobalCompactToSatisfyAllocate -Xconcurrentlevel1 -Xtgc:parallel",
"""
jvm = getServerJvm(nodename,servername)
AdminConfig.modify(jvm, [[propertyname, value]])
But I'm met with this issue when i run the script
WASX7017E: Exception received while running file "/etc/was-scripts/administrateservertest.py"; exception information: com.ibm.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "", line 14, in ?
NameError: maximumHeapsize
Any suggestions would be appreciated as I'm tearing my hair out trying to work this out
this was answered by a friend on face book
I think you might need to make two calls, one for each property you
want to set. e.g.
setJvmProperty(nodeName,serverName,'maximumHeapsize',2048)
For others looking for a more specific answer, try this:
AdminConfig.modify(jvmId,[['genericJvmArguments',arguments],["maximumHeapSize", str(1536)]])

I just upgraded from 3.1.17 to 4.1.1 and I'm finding a problem with my shopping lists.
When I get to /customer/shoppinglist/5064 I see this:
Looking at my log files from production I see:
[2020-06-23 17:42:56] request.CRITICAL: Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\UndefinedMethodError: "Attempted to call an undefined method named "getDigitalAsset" of class "Proxies\__CG__\Oro\Bundle\AttachmentBundle\Entity\File"." at /usr/share/nginx/html/oroapp/vendor/oro/platform/src/Oro/Bundle/DigitalAssetBundle/Provider/FileTitleProvider.php line 47 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Attempted to call an undefined method named \"getDigitalAsset\" of class \"Proxies\\__CG__\\Oro\\Bundle\\AttachmentBundle\\Entity\\File\". at /usr/share/nginx/html/oroapp/vendor/oro/platform/src/Oro/Bundle/DigitalAssetBundle/Provider/FileTitleProvider.php:47)"} []
I went to look at the code and I see that in fact there is no method getDigitalAsset in oro/platform/src/Oro/Bundle/DigitalAssetBundle/Provider/FileTitleProvider.php, nor in the proxy... how can this be?
I checked this on my VM (where the problem is not happening) and I see that there's this definition in the proxy class:
/**
* {#inheritDoc}
*/
public function getDigitalAsset()
{
$this->__initializer__ && $this->__initializer__->__invoke($this, 'getDigitalAsset', []);
return parent::getDigitalAsset();
}
But again, I don't see a method called getDigitalAsset in the parent class.
I had some issues when doing the upgrade (I realized my nodejs wasn't upgraded as I thought it was), could that have anything to do with the issue?
Thanks
Edit:
I went through my platform upgrade again and found that there were some problems that prevented it from finishing completely.
This is what I found:
> loading Oro\Bundle\CMSBundle\Migrations\Data\ORM\LoadImageSlider
In LoadImageSlider.php line 117:
Attempted to call an undefined method named "setMainImage" of class "Oro\Bundle\CMSBundle\Entity\ImageSlide".
I commented out the loop inside the load method and re-run the upgrade. Then I got:
> loading Oro\Bundle\CMSBundle\Migrations\Data\ORM\LoadImageSlider
In QueryException.php line 65:
[Semantical Error] line 0, col 117 near 'digitalAsset': Error: Class Oro\Bundle\AttachmentBundle\Entity\File has no association named digitalAsset
In QueryException.php line 43:
SELECT file, digitalAsset, sourceFile FROM Oro\Bundle\AttachmentBundle\Entity\File file INNER JOIN file.digitalAsset digitalAsset INNER JOIN digitalAsset.sourceFile sourceFile WHERE file.parentEntityClass = :parentEntityClass
AND file.parentEntityId = :parentEntityId AND file.parentEntityFieldName =
:parentEntityFieldName
Finally I was able to complete the upgrade by commenting out the whole body of the load method
I had some issues when doing the upgrade (I realized my nodejs wasn't upgraded as I thought it was), could that have anything to do with the issue?
It looks like you have multiple versions of nodejs installed. To make an application use the right one, you can provide the absolute path to the executable with the AssetBundle configuration, like:
# config/config.yml
oro_asset:
nodejs_path: /usr/local/node
npm_path: /usr/local/npm
I'm trying to write a script to test all DataSources of a WebSphere Cell/Node/Cluster. While this is possible from the Admin Console a script is better for certain audiences.
So I found the following article from IBM https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/txml_testconnection.html which looks promising as it describles exactly what I need.
After having a basic script like:
ds_ids = AdminConfig.list("DataSource").splitlines()
for ds_id in ds_ids:
AdminControl.testConnection(ds_id)
I experienced some undocumented behavior. Contrary to the article above the testConnection function does not always return a String, but may also throw a exception.
So I simply use a try-catch block:
try:
AdminControl.testConnection(ds_id)
except: # it actually is a com.ibm.ws.scripting.ScriptingException
exc_type, exc_value, exc_traceback = sys.exc_info()
now when I print the exc_value this is what one gets:
com.ibm.ws.scripting.ScriptingException: com.ibm.websphere.management.exception.AdminException: javax.management.MBeanException: Exception thrown in RequiredModelMBean while trying to invoke operation testConnection
Now this error message is always the same no matter what's wrong. I tested authentication errors, missing WebSphere Variables and missing driver classes.
While the Admin Console prints reasonable messages, the script keeps printing the same meaningless message.
The very weird thing is, as long as I don't catch the exception and the script just exits by error, a descriptive error message is shown.
Accessing the Java-Exceptions cause exc_value.getCause() gives None.
I've also had a look at the DataSource MBeans, but as they only exist if the servers are started, I quickly gave up on them.
I hope someone knows how to access the error messages I see when not catching the Exception.
thanks in advance
After all the research and testing AdminControl seems to be nothing more than a convinience facade to some of the commonly used MBeans.
So I tried issuing the Test Connection Service (like in the java example here https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.base.doc/ae/cdat_testcon.html
) directly:
ds_id = AdminConfig.list("DataSource").splitlines()[0]
# other queries may be 'process=server1' or 'process=dmgr'
ds_cfg_helpers = __wat.AdminControl.queryNames("WebSphere:process=nodeagent,type=DataSourceCfgHelper,*").splitlines()
try:
# invoke MBean method directly
warning_cnt = __wat.AdminControl.invoke(ds_cfg_helpers[0], "testConnection", ds_id)
if warning_cnt == "0":
print = "success"
else:
print "%s warning(s)" % warning_cnt
except ScriptingException as exc:
# get to the root of all evil ignoring exception wrappers
exc_cause = exc
while exc_cause.getCause():
exc_cause = exc_cause.getCause()
print exc_cause
This works the way I hoped for. The downside is that the code gets much more complicated if one needs to test DataSources that are defined on all kinds of scopes (Cell/Node/Cluster/Server/Application).
I don't need this so I left it out, but I still hope the example is useful to others too.
One question as just starting to use karate-gatling: is it possible to aggregate the reports generated? So after multiple runs to get one single report? It would be nice to be able to compare somehow the performance - to get automatically the information if there is a performance degradation or not. What I did try but did not work, was to copy the simulation logs and afterwards only generate the reports ("gatling.bat -ro simulations") but this did not work. The error that I got was:
gatling.bat -ro simulations/catskaratesimulation-1544015145031

Is there another way to do it? Should I somehow reconfigure gatling? Thanks!
It worked when using the same version (2.2.4) via gatling.bat -ro folder_with_simulations.
I need to capture the output of the below to a variable.
I know we can get to serverRuntime or domainRuntime() trees and get the state. But need to get the below working.
wls:/owb/serverConfig> state('Server1')
Current state of 'Server1' : RUNNING
I tried two ways:
wls:/owb/serverConfig> print state('Server1')
Current state of 'Server1' : RUNNING
None
wls:/owb/serverConfig> x=state('Server1')
Current state of 'Server1' : RUNNING
wls:/owb/serverConfig> print x
None
You have to use the getState() method of server runtime mbean.
You can obtain the server runtime mbean by navigating into wlst runtime tree or by using a lookup method.
Sample:
domainRuntime()
slrBean = cmo.lookupServerLifeCycleRuntime('Server1')
status = slrBean.getState()
print 'Status of Managed Server is '+status
See also Getting Runtime Information in WLST official documentation.
This same question was raised by Dianyuan Wang with me 2011.
Here is the steps to resolve your issue.
1. Capture the output of state command using redirect, stopRedirect command
2. Use the Python regular expression in search function to extract the desired server output.
Code snippet is here
fileName='/tmp/myserver_state.txt'
redirect(fileName)
state(server_nm,'Server')
stopRedirect()
f = open(fileName)
try:
for line in f.readlines():
if re.search('Current state',line):
status[server_nm]=line
except:
continue
Now you can apply desired logic after this block.
Cheers!!
HTH
Here is what I am using and is working like charm
cd("/ServerRuntimes/ms1")
state=cmo.getState()
print state
The code was run as:
u = subprocess.Popen(['process','abc','def','','ghi','jkl'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
It doesn't work below due to an error occurred:
ValueError: I/O operation on closed file
I suggest you to try pexpect, it is far more well-suited for this tasks (actually, it is a tool built for these kind of tasks).
You can also browse througn examples and see what its usage looks like.
