GridKA (Andreas): I/O problem observed: one node is very busy. Doris has sent an email to Dirk. We will need an account on the database and contact the dbas for help.
TCP tuning for Streams (Dirk D.):
Slides uploaded to the agenda
Motivation: slow transfers to BNL and Taiwan due to the network latency
Luca has run tests on tuning the application but they are not valid for Streams
Proposal: increase the TCP buffer size, apply this change consistently to all the sources and destinations using Streams
Florbela has run some tests using Oracle Net parameters
Eva will change the TCP buffer size on INTR and Floberla will repeat the tests changing the Oracle Net buffer size.
ATLAS COOL tests:
Capture process on integration got stuck. It was recreated but without using the last SCN already applied at the destinations so now there is a gap on the data
Eva propose to create a new capture process to re-capture the changes in the gap, it is necessary to determine the SCNs to start and stop the new capture
Wait event observed on the apply site: it is related to poor performance on RAC environments. To be investigated!
Problem with OEM, mail already sent to Dirk G.
CMS Frontier tests:
Segmentation fault problem: correlated to the second thread, Seal sw
Workaround: disable second thread. This will be better than request a bug fix on the Seal sw (it will take longer)
