I personnally hate the task of configuring Oracle as a DBMS. Unfortunately, many business use it since it has proven it’s stability, performance and scalability. Oracle is a good DBMS except for the IT guys who need to install it.
We were given a clean Sparc Sunblade 1000 running a brand new install of Solaris 10. The only requirement for our project was to configure Oracle to run a dedicated database server. Since we’ll eventually need high performance and probably load-balance this database between several servers, Oracle seemed the perfect solution.
First and second attempts to install an Oracle 11g database failed miserably with an out of memory error. The DBMS install would succeed but we were unable to create a new database.
Browsing the web lead to this blog post explaining our bug :
Solaris 10/Oracle: Fixing ORA-27102: out of memory Error
We had to increase the available memory for the privileged user section using this command:
prctl -n project.max-shm-memory -r -v 10G -i project 3
Good luck
