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 (Access Intent's of wsOptimisticUpdate or wsOptimisticRead) which is Cursor Stability (CS) for DB2. The remaining beans were accessed using REPEATABLE_READ (Access Intent's of wsPessimisticUpdate, wsPessimisticRead or wsPessimisticWeakestLockAtLoad) (which translates to DB2 isolation level of Read Stability (RS). The ItemEnt bean was cached for 20 minute intervals using the WebSphere Lifetime in Cache Mechanism. Only the data inside the bean was cached. |
Durability Requirement Info:
To ensure database durability, RAID 50 (composed of two RAID 5E arrays) was used for the database logs maintained on the EXP400 Storage Expansion Units. Each application server has a pair of mirrored disks (using the x365 integrated mirroring). This provides durability for XA transaction logs. |
Storage Requirement Info:
Over the course of a 90 minute run at an injection rate of 805, the database storage for database system #1 increased 678 MB; database system #2 storage increased by 1028 MB. Given a linear scale, a 24 hour run at the same injection rate would increase storage for database system #1 by 10848 MB and database system #2 by 16448 MB. The EXP 400 Disk enclosures each contain fourteen 36.4GB drives. The ServeRAID 6M adapter utilized these drives as a RAID 50 array consisting of two RAID 5E arrays of 7 drives each. This yields a total disk storage of 419879 MB for each EXP400 storage unit. |
Argument Passing Semantics:
WebSphere Application Server V6.0 uses pass-by-value semantics by default. |

Other Benchmark Information |
---|
The switch ports and all network adapters are 1Gb/sec. Two types of load balancing were utilized: WebSphere's workload management performed load balancing for RMI/IIOP requests. IBM Load Balancer balanced HTTP connections across the WebSphere nodes. This submission used the xerces implementation (version - XML4J 4.3) provided with WebSphere Application Server V6.0 in the IBM 1.4.2 JDK. |
General Notes |
---|
The only errors in the driver log files were those that are normally generated by this benchmark. The IBM DB2 Universal JDBC Drivers (XA and non-XA) 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 ?id=128770&coll=portal&dl=ACM&CFID=10343790&CFTOKEN=42047146) XA 2-phase transactions were used to coordinate the interaction between the database instances, and between database server and JMS servers. |
