Get over a quarter million transactions per second on Windows with Oracle10g

Oracle Tips by Burleson Consulting

UNISYS Corporation recently published a stunning TPC-C benchmark showing over 250,000 transactions per second on a Windows-based server using Oracle10g

While the details of the benchmark are included in the link, the high speed was primarily as result of these factors:

  • Multiple blocksizes

  • 115 gigabyte total data buffer cache

  • 78 gigabyte KEEP pool

  • 16 CPU Server – Each a 64-bit Itanium 2 Processor

In this UNISYS benchmark they achieved a stunning 291,410 transactions per minute.

To understand the Oracle component, here are a few of the Oracle10g parameters that were used in the benchmark:

db_block_size = 2048
db_16k_cache_size = 15010M
db_8k_cache_size = 1024M
db_cache_size = 8096M
db_keep_cache_size = 78000M

db_recycle_cache_size = 15400M
db_writer_processes = 4
pga_aggregate_target = 0
sort_area_size = 65525

Also of interest is the Oracle10g Windows registry entry ora_lpenable for large page support:


This tells Oracle to use the Large Page feature (available in Oracle9i 64-bit for Windows and Oracle10g 32-bit and 64-bit for Windows).

If you like Oracle tuning, see the book "Oracle Tuning: The Definitive Reference", with 950 pages of tuning tips and scripts. 

You can buy it direct from the publisher for 30%-off and get instant access to the code depot of Oracle tuning scripts.
