CPU For Oracle Database Server?
Jan 21, 2013
We have license for maximum six cores CPU, and we had to choose a server for Oracle single instance database with one of these two processors:
Intel Xeon E5-2643
============
#core: 4, #Threads: 8, Clock Speed: 3.3GHz, Max Turbo: 3.5GHz, Cache: 10MB, System Bus: 8GT/s, DDR3-max 1600, Memory Bandwidth: 51.2GB/s
Intel Xeon E5-2640
============
#core: 6, #Threads: 12, Clock Speed: 2.5GHz, Max Turbo: 3GHz, Cache: 15MB, System Bus: 7.2GT/s, DDR3-max 1333, Memory Bandwidth: 42.6GB/s
For database server what is more important, number of cores, cache, or clock speed, system bus, or DDR speed and memory bandwidth?

I will have to proceed with Oracle 9 database refresh from production server to integration server. 5 biggest schemas must be exported and imported. They constitute 97% space used in a database. This is very big database so I would like to be sure that everything will go smoothly. That is why i want to ask you some questions.
Have you got any clues for me before I start with exp/imp? From my side i will tell you that I will have to exp/imp schema by schema because there is small space both on production and integration disk for a dump. First thing I thought are dependencies between schemas that are exported and that which are not, and also between schemas that are exported/imported one by one.
This is procedure that I plan:
For every schema that is to be refreshed
{
1. Export schema with ROWS=N CONSTRAINTS=Y
2. EXPORT schema with ROWS=y CONSTRAINTS=N
3. Import schema from step one
4. Disable all the foreign key constraints using ALTER TABLE DISABLE CONSTRAINT.
5. Import schema with rows
}
ALTER TABLE ENABLE CONSTRAINT
With above procedure i think that I will avoid problems with dependencies between schemas exported/imported one by one. But my concern is if there are any dependencies between those schemas and schemas that are not exported. Is there an way to check it before refresh ?

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'

Currently I am doing one Oracle installation.But very much confused where to start from. Since I am installing oracle on my personaly Laptop,do I need to install Oracle database server and Oracle client both or only installing database server is sufficient.
What is the exact difference between oracle database server and client.Only knowledge I have is that client is used to access database server remotely.are Oracle database server and client installable to be downloaded separately?

I'm getting the error messaage:
Database Connection failure. Reason: java.sql.SQLException: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory
I'm not an Oracle expert, but I have research a little and seems that the SID could be wrong or that the DB is down, in fact I have already checked trhe server but everything seems normal to me.
