Question
why we need access group for node level data page ?
when access group is not required for thread and requester, why we need access group for node level data page and its a mandatory one ?
Requester Access Group is not sufficient as like thread and requester ?
I have got an article about same but did not understand, what is the real necessity of access group for node level page.
Can any one explain me more in detail of it.
Hello,
If a Data page is specified in a node level, it can be accessed by all the requestors in that particular node.
As we are aware that rule resolution works based on the requestor access group, for a node level, we may have different requestors with different access groups per node.
If a access group is specified in load management tab then Pega uses this access group to identify the data source activity using rule resolution and load the data.
Thank you!
Hi,
Thanks for your answer, its really helped me.
I understand the point you mentioned, but I'm uncleared about one point mentioned below.
Generally the data pages will get load, whenever we refer that particular data page right. So my point is, some user has to be go that particular place (referenced place in case or in dashboard) where data page has been used to load the data right. In that particular time the node level data page can use the, this particular user's or requester access group right.
When some one intervention or referenced place to be launch, required to load the data from data page, then what is the need to have separate access group for Node level data page. It can use the same requester access group right ?
Answer to my another point which I raised is,
Generally rule resolution will works on access group to find load activity to load data on to data page. And generally Data page will load data only when it referenced in some place. that time it can consume that particular requester access group to load data, there no problem system can use that. But the point of or the utility of data page is to load one time and share the data to all the requesters connected to particular node.
If it use every requester access group, then it has to load for every requester. Then it loose the concept of Node level Data page.
So for this reason only we have maintain a separate access group for node level data page to invoke load activity to load the data and it can be shared between all the requesters connected to that particular node.
Thanks, it can be helpful to others who has a confusion with this point.
Hello,
Thanks for posting query on PSC.
The AccessGroup field identifies the access group that PRPC uses at runtime to locate the load activity that populates the page.
