Benchmark Configuration Information
Isolation Requirement Info: The benchmark meets the isolation level requirements by version column checking on entities against the database. The ItemEnt bean was cached for 20 minute intervals using the WebSphere JPA Object Cache mechanism.
Durability Requirement Info: To ensure database durability, the database and the database logs were each maintained on 2 mirrored internal 1.2TB SSD drives configured in RAID 1.
Storage Requirement Info: Over the course of a 85 minute run at an injection rate of 12095, the database storage increased by 16.7 GB Given a linear scale, a 24 hour run at the same injection rate would increase storage by 282.9 GB. The database was configured with over 1058 GB of mirrored storage.

Other Benchmark Information

  DNS round robin load balancing was used and hosted on the database machine
  Load balancing network connectivity was 1Gbps all other connections were 10Gbps
  Database connectivity utilizes Java Sockets over Remote Direct Memory Access

General Notes

All exceptions in driver logs are from Optimistic Concurrency Checking.
These exceptions are expected in the benchmark.

The IBM DB2 Universal JDBC Drivers is a type 4 driver.

DB2 uses "Soft" checkpoint to ensure that no updates remain unflushed for
longer than the allowed time.

When DB2 UDB Server changes a database table with an update, insert, or delete
operation, the change is initially made in memory, not on disk. When there is
not enough space in the memory buffer to read in or write additional data pages,
DB2 UDB Server will make space by flushing some modified pages to disk.
Modified pages are also written to disk as part of the "Soft" checkpoint to
ensure that no updates remain unflushed for longer than the allowed time.
Before a change is made to the database, it is first recorded in the
transaction log. This ensures that the database can be recovered completely
in the event of a failure. Using the transaction log, transactions that
started but did not complete prior to a failure can be undone, and
transactions recorded as complete in the transaction log but not yet written
to disk can be redone.

DB2 UDB uses a write-ahead-logging protocol to guarantee recovery. This
protocol uses "Soft" checkpoint to write least-recently-used database pages
to disk independent of transaction commit. However, enough log information to
redo/undo the change to a database pages is committed to disk before the
database page itself is written. This protocol therefore renders checkpoint
unnecessary for DB2 UDB. For a more detailed description of the general
principles of the write-ahead-logging protocol, see the IBM research paper,
ARIES: A Transaction Recovery Method Supporting Fine Granularity Locking and
Partial Rollbacks Using Write-Ahead Logging," by C. Mohan, Database Technology
Institute, IBM Almaden Research Center. (http:// portal.acm.org/citation.cfm
