VLM in Linux
esears1Jul 25 2007 — edited May 24 2009I have setup a new linux box using Oracle's Enterprise Linux update 4 and installed Oracle 9iR2 successfully. I am using this box for testing purposes to see if we really want to go to linux. On the Windows side of things, i made VLM adjustments (/pae /3gb/, use_indirect_data_buffers, etc) to increase performance since we have 16GB of memory on a 32-bit machine. I have read the article from www.puschitz.com that explains how to do it in linux but i'm having a problem. I know it's a setup issue.
I have db_block_buffers set to 8GB, shmmax set to 3 GB, i also set the /dev/shm file so oracle has writes to it.
When i start the database, it gets all the way to mounting it, but when it tries to open the database, it will lose connection, i'll get a ORA-07445 error in the alert.log. Basically oracle is not up.. so i eventually have to do a shutdown.
Can anyone help? I just want to be able to use db_block_buffers like i do in windows with a large amount like 8GB.
