Hello Natsuka,
Thanks a lot for your response. 'Initial Reorg' meaning , the BIA re-org that has to be done when RSDDBIAMON2 tcode indicates a reorg is required ; is it ?
Fortunately this time (probably due to a lot less loading happening during night) BIA rebuild was successful for this cube.
But we are sure again these problems will arise again particularly during Book Closure. Your response will be quite handy then.
Looks like TREXIndexServer got restarted as per your analysis probably due to high usage of BIA. Thanks again. Cheers !
Regards,
Vijay Dasari.
