All nodes were restarted after making these changes. The alert log entry is as follows:
...PEGA0017*1000*1000*...;*declaratives/declarepages: Successfully reduced Concurrent MRU Map by201 down to: 1000.*
The alert log shows the threshold is 1000 as if my changes never took effect. How do I overcome this?
Also, it would be helpful if all prconfig settings were documented so I could determine if I am adding the proper dynamic system setting for this issue. A search on PDN does not bring up any results. Does anyone have any info on that?
I have checked the source code, datapages/mrucapacity is a real DSS (owning ruleset Pega-RULES, not a prconfig setting), like Vipin said, you need to add it that way, the default value is 1000 for 7.1.5.
