Not have a strong background on the Z Platform I wonder if the team might have some feed back regarding the following topic.
Our DBAs have been approached with a dilemma. It seems that they can acquire larger Sun servers to accommodate two new Databases or they can investigate the option of placing these new images under Z/Linux, specifically SLES8 with Z/VM 4.4. The limited information I have regarding the DB follows: SGA 2.0 GB each. (two databases are required) Purpose: Development usage Current Z/Linux configuration: 1 IFL 2 GB of Physical Memory Currently have 2 SLES 8 guests running OpenLDAP 2.x server services 1 GUEST for WEBSPHERE Portal development (rarely used) 1 GUEST for WEBSPHERE 5.0 Development and testing (rarely used) 1 GUEST for my development and test work (rarely used) 1 GUEST for "GOLD Image" development I need to understand if I will be able to start these databases on this system, as many probably know Oracle will not start its databases if the memory is not available. I also need to understand if I will run into problems with creating additional guests in the near term? If it is believed that these databases would run in this configuration what size should I allocate to these guests to start? Should there be a dynamic high memory allocation, if so what? I have the DBAs reading the Red Paper now on Oracle 9i under Z/Linux. Any feedback would be appreciated. thank you! Eric Sammons (804)697-3925 FRIT - Unix Systems
