Benchmark Modifications
Schema Modifications: Tablespace sizes were increased to support the Injection rate. Scripts to create the DB are included in the FDA.
Load Program Modifications: The load program was not modified

Benchmark Configuration Information
Isolation Requirement Info: The following beans: PartEnt, ComponentEnt, AssemblyEnt, BomEnt and LargeOrderEnt in the Manufacturing Domain, ItemEnt in the Orders Domain, and SupplierCompEnt and SupplierEnt in the Supplier Domain were accessed using READ_COMMITTED which is Cursor Stability (CS) for DB2. The remaining beans were accessed using translates to DB2 isolation level of Read Stability (RS) The ItemEnt bean was cached for 20 minute intervals by setting concurrency-strategy to ReadOnly and read-timeout-seconds to 1200 in bea-orders.xml deployment descriptor.
Durability Requirement Info: To ensure database durability, RAID 1 (mirror disks) was used for the database files and logs on the four Sun StorEdge 3510 arrays. Each application server has a pair of mirrored disks (using onboard controller) to provide durability for all the server logs and filestore for JMS persistence.
Storage Requirement Info: An 85 minute run at an injection rate of 4320 increased storage by 4841 MB This extrapolates to 80 GB of storage for a 24 hour run. The database is configured with 6132 GB of storage. Each Sun StorEdge 3510 FC Array was configured as a single RAID 1 logical drive.
Argument Passing Semantics: BEA WebLogic 9.2 uses pass-by-value as required by the EJB Specification.

Other Benchmark Information

  The submission used round-robin DNS for load-balance of
  all network requests. The DNS server was hosted
  on the database server.
  
  This submission used the xerces implementation 2.6.2 provided
  with WebLogic 9.2

General Notes

The only errors in the driver log files were those that are normally generated
by this benchmark.

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
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.
