Hi Mahesh, Ticket #195 introduced this limitation.
After all, I'm not sure who is right... Neelakanta or me :) Earlier, we didn't have any limitation, and limitation is introduced to have some reasonable amount of CCB handles in IMM. IMM keeps non-used and active CCB handles in the same place. If the amount of CCB handles grows a lot, then we will see a degradation of IMM performance. >From earlier discussion with Anders, it's not meant from the beginning that >CCB will be used so often. This might be very specific case. That's also the >reason why CCB handles are handled in a way that is not good for huge amount >of CCB handles. >From this point of view, Neelakanta is correct. >From my point of view, we should only consider CCBs that can be used. I don't >see acceptable that CCB operations cannot be done for minutes if we have a >huge amount of closed CCBs. We can improve CCB handling in the next OpenSAF release. Now it's too late. For this particular problem, I would go with checking only CCBs that can be used (CCB that have SA_AIS_OK on mVeto variable, or calling ->isOk() method on CcbInfo struct). This solution may have impact on IMM performance. Or we can revert the ticket and implement it in the next release with better performance. I would also like to hear Neelakanta's and Hung's proposals.
