Maximum number of concurrent reports 10g

Question

Hi all,
We hava an application with two backgroundprocesses running a maximum of 1 report at the same time so in total 2 reports. Also user are allowed to run reports we however do not want them to run more reports at the same time so in total max 3 reports at the same time additonal reports should be stalled to keep performance up.
How can this be setup in reports 10g ?

Answer 1

1) In the entry Jon has given
<engine id="rwURLEng" .....
>
You should actually do it for
<engine id="rwEng" ...
>
The second one is the one which is used for running reports created through builder and is the most common one (99.99%).
(For URLEngine you can keep 1 engine or 0 engine)
Also
engLife="1".
This is very inefficient. You can put it to "engLife="50". [Otherwise an engine will run only 1 job and a new engine will be spawned. Infact it can run any number of jobs. This life is there only because if there is any small memory leak for a request, it will pile up for very large number of jobs. You can safely put it to 50 (default) ]
2) >>>> will your solution give a message that reportsserver is busy or will it set up a queue <<<<
If more requests come than the number of engines, then those reports will be queued and will be executed as and when engines become free.
3) Reports engine is actually very fast and unless reports are huge, it will complete a report in short time.
According to the load , you should arrive at a "maxEngines" for your server.
If it is too much your machine will crawl ("it" I mean - Number of engines)
If it is too less jobs will get queued
You should come to a balance.
4) I do not know whether any mechanism exists to restrict the max reports run by a user to 1 at a time.
5) Refer Chapter 19 and 20
