on our tamino servers (RHEL-5.7) we have a a huge i/o load approximately every 3 hours, so at this point the server load is growing nearly 8.00 for some minutes and so the users claims the app is slow or freezing for a while.
We saw at this peaks there´re database operations
-rw-rw-rw- 1 tamino tamino 3.6G Nov 30 15:09 AAE00001.1I0
-rw-rw-rw- 1 tamino tamino 6.0G Nov 30 15:09 AAE00001.1D0
-rw-rw-rw- 1 tamino tamino 22M Nov 30 15:09 AAE000010.1T0
but i cant figure out what´s going on there. Are this internal jobs in the database? Maybe the “temporary working space” wass written in the database or something like this? How can we reduce this peaks or optimize this?
Any hints are welcome
