Timer for applying settings WSO2 API-manager doesn't work - caching

I have used the WSO2 API manager in my company. When I change the settings of the available methods (scopes) or the available authorisation methods (application level security), the application of these settings takes up to 15 minutes (I tested the work of the methods through postman). This is a lot for running tests.
I followed the recommendation to change the timeout in the deployment.toml
[apim.cache.resource]
enable = true
expiry_time = "900s"
There were no such settings in my config, but I added them and change for 60s. After the reboot, the settings were applied instantly (not even after 60 seconds). However, after a while, the settings were applied again after 15 minutes. I disabled the cache altogether, but it didn't help the as well. Settings are applied quickly only the first time after restarting WSO2. Has anyone had the same problem?

In WSO2 APIM if you update an API, the resource cache gets invalidated and the changes are reflected within a few minutes. If you want to apply the changes quickly you can restart the server and check the flow.
The default cache size of any type of cache in a WSO2 product is 10,000 elements/records. Cache eviction occurs from the 10001st element. All caches in WSO2 products can be configured using the <PRODUCT_HOME>/repository/conf/deployment.toml file. In case you have not defined a value for default cache timeout under server configurations, the defaultCacheTimeout of 15 minutes will be applied which comes by default.
[server]
default_cache_timeout = 15
Please refer https://apim.docs.wso2.com/en/3.0.0/administer/product-configurations/configuring-caching/ for further details on caching.

Alfresco session timeout

We are using alfresco 5.2.3 enterprise with ADF 3.4.0
The web.xml files in our both alfresco and share war has 60
And for ADF we have not found any session timeout settings or config.
So, ideally the session should not expire before 60 mins, but the customer is complaining that after remaining idle for around 15 mins, their session expires/logs out. They need to relogin.
So, what should be the ideal way to make the session valid for actual 60 mins and not just 15 mins.
I tried overriding the session timeout using the following link but it's not working:
Overriding alfresco timeout
Also tried setting the following property in alfresco-global.properties file with different values:
authentication.ticket.validDuration=PT1H
But does not work.
The same behaviour is noted when we use ADF url as well as Share url.
Share Url actually logs out the user, ADF url mostly invalidates the session so our custom actions do not appear against the documents if user remains idle for 15 mins.
NOTE: There is no SSO integration done for our project.
Any suggestions or pointers would be really helpful.
I tried out with multiple options:
authentication.ticket.ticketsExpire=true
to
authentication.ticket.ticketsExpire=false
authentication.ticket.expiryMode=AFTER_INACTIVITY
to
authentication.ticket.expiryMode=DO_NOT_EXPIRE
authentication.ticket.useSingleTicketPerUser=false
to
authentication.ticket.useSingleTicketPerUser=true
But, none of the above settings after restart give any impact on the behaviour. So, this session timeout settings are mostly carried forward from the proxy server or load balancer settings and applied here.

WSO2 ESB Cache when using GReg mount

I've followed this sample: https://docs.wso2.com/display/ESB490/Governance+Partition+in+a+Remote+Registry
Everything works well: I have a list of endpoints in governance part of my GReg that are added through a Carbon Application Artifact(.car). The ESB mounts this repository to see those endpoints and use them. Perfect!
But, when modifying the endpoints in Greg Console (for example, updating the URL of the endpoint), it's not refreshed in ESB Console. Only after around 10 to 15 minutes, updates appears.
I guess, there is Cache configuration to add/update to take in account this remote governance?
Any help appreciate please :)
This is due to the caching timeout of ESB which is default set to 15 minutes. When an artifact is deployed in G-Reg node it takes about 15 minutes to be visible in ESB node.
You can reduce this caching timeout duration in "/repository/deployment/server/synapse­configs/default/registry.xml" file as belows.
<registry provider="org.wso2.carbon.mediation.registry.WSO2Registry">
<parameter name="cachableDuration">15000</parameter>
</registry>
But changing this value will also have performance impact. If this value is too low, searching for resources would be done in the database, because most of the resources will be missing in the cache.

Service Fabric Resource balancer uses stale Reported load

While looking into the resource balancer and dynamic load metrics on Service Fabric, we ran into some questions (Running devbox SDK GA 2.0.135).
In the Service Fabric Explorer (the portal and the standalone application) we can see that the balancing is ran very often, most of the time it is done almost instantly and this happens every second. While looking at the Load Metric Information on the nodes or partitions it is not updating the values as we report load.
We send a dynamic load report based on our interaction (a HTTP request to a service), increasing the reported load data of a single partition by a large amount. This spike becomes visible somewhere in 5 minutes at which point the balancer actually starts balancing. This seems to be an interval in which the load data gets refreshed. The last reported time gets updated all the time but without the new value.
We added the metrics to applicationmanifest and the clustermanifest to make sure it gets used in the balancing.
This means the resource balancer uses the same data for 5 minutes. Is this a configurable setting? Is it constraint because it is running on a devbox?
We tried a lot of variables in the clustermanifest but none seem to be affecting this refreshtime.
If this is not adaptable, can someone explain why would you run the balancer with stale data? and why this 5 minute interval was chosen?
This is indeed a configurable setting, and the default is 5 minutes. The idea behind it is that in prod you have tons of replicas all reporting load all the time, and so you want to batch them up so you don't spam the Cluster Resource Manager with all those as independent messages.
You're probably right in that this value is way too long for local development. We'll look into changing that for the local clusters, but in the meantime you can add the following to your local cluster manifest to change the amount of time we wait by default. If there are other settings already in there, just add the SendLoadReportInterval line. The value is in seconds and you can adjust it accordingly. The below would change the default load reporting interval from 5 minutes (300 seconds) to 1 minute (60 seconds).
<Section Name="ReconfigurationAgent">
<Parameter Name="SendLoadReportInterval" Value="60" />
</Section>
Please note that doing so does increase load on some of the system services (TANSTAAFL), and as always if you're operating on a generated or complete cluster manifest be sure to Test-ServiceFabricClusterManifest before deploying it. If you're working with a local development cluster the easiest way to get it deployed is probably just to modify the cluster manifest template (by default here: "C:\Program Files\Microsoft SDKs\Service Fabric\ClusterSetup\NonSecure\ClusterManifestTemplate.xml") and just add the line, then right click on the Service Fabric Local Cluster Manager in your system tray and select "Reset Local Cluster". This will regenerate the local cluster with your changes to the template.

Are Changes Made to the CRM Unsecure Configuration Settings of a Plugin Instantaneous

If I have some configuration changes in the Unsecure (does it matter?) Configuration Settings, and I make a change, will that force all instances of the plugin to get the newest settings, or does it take a while for the configuration settings to propagate?
The change does have to propagate to each front end web server, so I have definitely seen very short delays before, but I'm talking seconds. The vast majority of the time, as soon as I hit Update Step and then initiate whatever action in the UI, I can see that the plugin ran with the updated configuration value.
I'm less sure about delays when it comes to plugins running in the async service. Meaning, if 30 async plugins/wfs are queued up, you make your config change, I'm not sure if those queued up async jobs will use the new value or the old.
One easy way to investigate this would be for your plugin to write to the trace log and then set the trace log level in system settings to all. Plugin-trace log records show what configuration values the plugin ran with.

wso2 IS sp1 session management contd

I would like to know whether session data persistence
<SessionDataPersist>
<Enable>true</Enable>
<RememberMePeriod>..</RememberMePeriod>
<CleanUp>
<Enable>true</Enable>
<Period>..</Period>
<TimeOut>..</TimeOut>
</CleanUp>
<Temporary>false</Temporary>
</SessionDataPersist>
which is available as part of WSO2 IS SP1 is only applicable when Remember me option is selected? Is there any other config where we manage these session timeouts?
Regards,
Cijoy
If you do not enable the session persistence, WSO2IS invalidates the SSO session after 15 minutes inactive time and the value is not configurable as it is the cache invalidation time. WSO2IS 5.0.0 just stores the SSO session in caches which is not correct and which can leads to lot of issues. Then WSO2IS 5.0.0 SP1 introduces the session persistence. So; currently there is no configuration to define the session timeout explicitly. But timeout can be happened, when these session can be deleted.
Therefore timeout can be achieve with cleanup task but it is not an inactive time out.
<CleanUp>
<Enable>true</Enable>
<Period>10</Period>
<TimeOut>60</TimeOut>
</CleanUp>
CleanUp.Period defines the time period among two consecutive cleanups in minutes. By default it is 1 day.CleanUp.TimeOut defines the timeout value of session data in minutes. By default it is two weeks.
For an example if we consider the above configuration it means that the clean up task will run periodically with a period of 10 minutes.
And in a cleanup process it will remove all session data persisted before 60 minutes.
