I'm trying to write some JMX code to manage Weblogic sessions. Ideally, what I'd like to be able to do is to find a session based on some attribute in the session and then be able to invalidate that session. However, I haven't been able to figure out if there is anything that I can do to accomplish this. Using the DomainRuntimeServiceMBean I can drill down and get the WebAppComponentRuntimeMBean. From there I can get sessions either by session id or by monitoring id. However, what I want to do is to find a session by some attribute in the session. Say, I have an attribute called "externalSessionId" and I want to be able to find a session with a particular value of this attribute - is that doable?

I would like to maintain comma separated lists of entries of the following form <ip>:<app> indexed by a an account ID. There would be one such list for each user indexed by their account ID with the number of users in the millions. This is mainly to track which server in a cluster a user using a certain application is connected to.
Since all servers are written in Java, with Redisson I'm currently doing:
RSet<String> set = client.getSet(accountKey);
and then I can modify the set using some typical Java container APIs supported by Redisson. I basically need three types of updates to these comma separated lists:
Client connects to a new application = append
Client reconnects with existing application to new endpoint = modify
Client disconnects = remove
A new connection would require a change to a field like:
1.1.1.1:foo,2.2.2.2:bar -> 1.1.1.1:foo,2.2.2.2:bar,3.3.3.3:baz
A reconnect would require an update like:
1.1.1.1:foo,2.2.2.2:bar -> 3.3.3.3:foo,2.2.2.2:bar
A disconnect would require an update like:
1.1.1.1:foo,2.2.2.2:bar -> 2.2.2.2:bar
As mentioned the fields would be keyed by the account ID of the user.
My question is the following: Without using Redisson how can I implement this "directly" on top of Redis commands? The goal is to allow rewriting certain components in a language different than Java. The cluster handles close to a million requests per second.
I'm actually quite curious how Redisson implements an RSet under the hood and I haven't had time to dig into it. I guess one option would be to use Lua, but I've never used it with Redis. Any ideas how to efficiently implement these operations on top of Redis on a manner that is easily supported by multiple languages, i.e. not relying on a specific library?
Having actually thought about the problem properly, it can be solved directly with a HSET. Where <app> is the field name and the value are the IPs. Keys being user accounts.
i have defined a dev.properties file for the mule flow.where i am passing the username and password required to run the flow.This password gets updated everymonth.So everymonth i have to deploy the code to the server after changing the password.Is there a way , where we can keep the properties file outside the code in mule server path.and change it when required in order to avoid redeployment.
One more idea is to completely discard any usage of a file to pickup the username and password.
Instead try using a credentials providing service, like a http requestor which is collecting the username and password from an independent API(child API/providing service).
Store it in a cache object-store of your parent API (the calling API). Keep using those values, unless the flow using them fails or if the client needs to expire them after a month. Later simply refresh them.
You can trigger your credentials providing service using a scheduler with a Cron expression having Monthly Triggers.
No, because even if the properties file is outside the application, properties are loaded on application deployment. So you would need to restart the application anyway to pick up the new values.
Instead you can create a custom module that read the properties from somewhere (a file, some service, etc), assign the value to a variable, and use the variable instead at execution time. Note that some configurations may only be set at deployment time, so variables will not be evaluated as such.
If the credentials are not exposing your application security or data, then you can move them to another config file(place it Outside mule app path). Generate a RAML file which will read & reload the credentials after application deploy/start-up, and store them in cache with timeToLive around 12 hours.
The next time when you have to change Username/Password, change in the file directly and cache will refresh it automatically after expiry time.
Actually not because all the properties secure properties needs to be there at runtime and is it is not there your application will get failed,
There is one way but it’s not best one, instead of editing code you can directly edit secure property I.e username and password in your case directly in cloudhub runtime manager properties tab.
After editing just apply changes then api will restart automatically and will deploy successfully
Is there a way to test if current user has been authenticated to BBG? I have my c# program which uses BBG API, and want to check if the user logged in the service before, either via API calls or the BBG Terminal. This check can then be used to distinguish whether the user's network is unavailable or simply he hasn't logged in yet.
Thanks!
There's a couple of ways to interpret your question, so I'll answer both... (I'm speaking from the perspective of using the Java API, but it should be pretty similar on C#.)
1. Can I tell whether the user connect to Bloomberg (i.e. are there network issues / are they are logged in)?
Yes - you can create a new Session, try to start it using .start(). If it fails or returns false, you cannot connect. If it starts, you can call .openService("//blp/apiauth"). Again, if it fails or returns false, you cannot connect.
If you cannot connect, you may or may not be able to determine why you cannot... Nevertheless, I would suggest registering a callback to the BLP API logging framework. In our code, we we-direct these to the logging framework we use throughout our code.
2. The user has created a Session (pre-cursor to a Service) - can I tell if the Session has been started?
Unfortunately - no. There is nothing in the API to allow you to determine the state of the Session. (I suppose you could try starting it, and if it starts it wasn't started, and if it fails, it was started - but that strikes me as an unhelpful or risk appraoch.)
I'm inserting several ApexTestQueueItem records into an Org via the Partner API to queue the corresponding Apex Classes for asynchronous testing. The only field I'm populating is the ApexClassId. (Steps as per Running Tests Using the API)
After the tests have run and I retrieve the corresponding ApexTestResult record(s) the ApexLogId field is always null.
For the ApexLogId field the help documents have the Description:
Points to the ApexLog for this test method execution if debug logging is enabled; otherwise, null
How do I enable debug logging for asynchronous test cases?
I've used the DebuggingHeader in the past with the runTests() method but it doesn't seem to be applicable in this case.
Update:
I've found if I add the user who owns the Salesforce session under Administration Setup > Monitoring > Debug Logs as a Monitored User the ApexLogId will be populated. I'm not sure how to do this via the Partner API or if it is the correct way to enable logging for asynchronous test cases.
You've got it right. That's the intended way to get a log.
I want to store values in variables to access form another page (a.k.a State management).
Now I cannot use sessions since I have multiple Zope instances & if one fails the user need to be redirected to another Zope instance and one session is valid only for one Zope instance.
Now my remaining options are
submit a Hidden input tag using POST method
Passing through URL with GET method
Using cookies
Using Database (which I think is 'making simple things complex'.)
I am not even considering the first 2 methods and I think using cookies is not secure.
So is there a commercial or open source module that can securely (encryption etc.) do cookie management.
If not I will have to use a database.
Please inform me, if I am missing something.
Version - Zope 2.11.1
The SESSION support built-in to Zope 2 actually keeps the session in a temporary partition of the ZODB so I think it actually is valid for multiple Zope clients connecting to the same ZEO server. The cost of this is that all session changes invoke the transaction machinery and result in a commit, so just make sure you're not using the SESSION in something very low-level like PAS auth or you'll have commits hitting your ZODB for every image, CSS file, and JS file.
