Go to Advanced --> Conclusion Cache
hi othos
I want to make sure , whether this action affect the activity developer? such as the check out / in?
Hi Ryan,
It will impact performance as these caches needs to be rebuilt.
hi othos,
I've tried it, but the problem is still there.
what to do afterward? or is there any other suggestions??
thanks & regard
Hi Ryan,
Thanks for the update.
This may require deeper analysis. Kindly try the suggestion posted by MERLX and raise an SR if you require further assistance.
Are you getting any error in hazelcast?
Share your log file, that might give us hint where Pega is looking that rule.
hi ranjr,
I think it's one of the problems , and has been posted on the forum by my colleague.(https://pdn.pega.com/community/product-support/question/pega-cannot-run-after-restart-server)
but in this case, I use another server ( 2 server but 1 schema DB ), according to my logic, there should be no problem. but after I open one class or property error occurs as described in attachment.
can u help me :)
thanks
hi,
Can I delete this class affected by this problem ?
because when i try to create propery , there are message error .
Error: You lack access required to execute Rule-Obj-Activity.pzViewInstancesResetDataPage .
please, need help :D
thanks
I suggest you double-check the class really exist by looking straight in the database.
Also you can try to open it via activity OpenByHandleDD. I forgot the exact synthax of the parameter you need to use so test first with a class you have access.
Classes are saved in table pr4_base. Check via some SQL query that the class really exists.
You may see the class in app explorer as PRPC may save the class information in some other tables for performance for example. This can happen if someone deleted the class straight from the database and not via PRPC developer portal. A symptom of this is for instance seeing the class via a search (as it still indexed) but not able to open it which similar error as the one you have shown.
If the class does exist then this suggest a permission issue.
If the class doesn't exist Then you could attempt to just create a new one with the same name.
If this is going to deep, I recommend you raise a service request.
