How to optimize code for getting list of portal GP erroneous processes

Question

Hello,
In our Web Dynpro application for Java we got the list of GP processes with status Erroneous which match the following criteria (initiator, processName, blockName, actionName, startDate, endDate, instanceName, actionProcessor) by loop of all portal users. The problem is that it takes too much time for execution. In example with 200 users it takes about 5 min. Any idea how to optimize execution?

Answer 1

got the answers ..
we have use IndexedRecord instead of MappedRecord
               IndexedRecord input = rf.createIndexedRecord("input");
               boolean flag = input.add("/FolderpathValue");
               flag = input.add("CampusCodeValue");
