The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

SGA limited to 2GB

Asked by scirocco1 in Oracle Database

Tags: oracle

Hi everybody,

I'm configuring a production server with Oracle 8.1.7. My server is a Dell equiped with 8gb and 4 Cpu's Xeon running @ 800 Mhz. The operating system is Windows 2000 Advance Server(Updated). My real problem is that after configuring the server with the /PAE flag at the boot.ini, I'm still getting low performance on my Oracle database and my SGA is limited to 2GB no matter what configuration I set at the ora.ini file. I think I'm doing something wrong.

My ora.ini file looks like and my database is approx 20gb in size:
*********************************************************************
background_dump_dest = E:\oracle\admin\DCSI\bdump
compatible = 8.1.0
control_files = "E:\oracle\oradata\DCSI\control02.ctl"
control_files = "E:\oracle\oradata\DCSI\control01.ctl"
control_files = "E:\oracle\oradata\DCSI\control03.ctl"
db_block_buffers = 100000
db_block_size = 8192
db_file_multiblock_read_count = 32
db_files = 1024
db_name = DCSI
distributed_transactions = 500
global_names = FALSE
instance_name = DCSI
instance_number = 1
java_pool_size = 20971520
job_queue_interval = 10
job_queue_processes = 5
large_pool_size = 614400
log_archive_dest = E:\oracle\oradata\DCSI\archive
log_archive_format = "%%ORACLE_SID%%T%TS%S.ARC"
log_archive_start = TRUE
log_buffer = 2457600
log_checkpoint_interval = 100000
log_checkpoint_timeout = 3200
max_dump_file_size = 10240
max_enabled_roles = 30
mts_dispatchers = "(PROTOCOL=TCP)(PRE=oracle.aurora.server.SGiopServer)"
open_cursors = 1500
open_links = 4
oracle_trace_collection_name = ""
os_authent_prefix = ""
parallel_max_servers = 16
processes = 400
remote_login_passwordfile = EXCLUSIVE
service_names = DCSI
shared_pool_size = 80000000
sort_area_retained_size = 65536
sort_area_size = 65536
use_indirect_data_buffers = TRUE
user_dump_dest = E:\oracle\admin\DCSI\udump
utl_file_dir = *

Right now I'm using both /3GB and /PAE looking for answers, but the response was the same, just 2GB for SGA and when monitoring the processors performance they get up to 100% utilization.

Does anybody has any idea what could be wrong in my configuration?
