Benchmark Configuration Information |
Persistence Mode Used:
All beans were deployed using Container Managed Persistence (CMP).
|
Isolation Requirement Info:
All beans were deployed with the isolation level set to REPEATABLE_READ. DB2
translates this isolation level to Read Stability. Read Stability ensures
that all rows referenced in a transaction have a read-lock associated with
them to ensure that other transactions cannot change the rows until the first
referencing transaction completes.
The following bean finder methods were deployed to use a FOR UPDATE clause
on the SELECT during bean hydration:
Mfg:
Inventory.findByPrimaryKey
Orders:
Order.findByCustomer
Order.findByPrimaryKey
Orderline.findByOrder
Orderline.findByOrderAndItem
Orderline.findByPrimaryKey
Supplier:
SComponent.findByPrimaryKey
PO.findByPO
POLine.findByPO
POLine.findByPrimaryKey
Util:
Sequence.findByPrimaryKey
|
Durability Requirement Info:
All drives on the system were configured with RAID-5. Database changes were
journalled to disk prior to the completion of each transaction commit.
|
Storage Requirement Info:
A 45 minute run at an injection rate of 480 increased storage use by 6.8 GB.
Given linear scaling, eight hours of run time would at that rate will require
72.6 GB of space. The system was configured with 789.3 GB of disk storage
(631.4 GB after enabling RAID-5 protection). Over 560 GB of free space was
available prior to each run.
|
Argument Passing Semantics:
WebSphere Application Server uses pass-by-value semantics by default. This can
be confirmed in WebSphere's output when starting the application server by the
following message:
JORB0012: Pass by reference has been set to: false (NoLocalCopies = false)
