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, RAID10 was used for the database logs maintained on the external storage. A total of 12 x 146GB disks were used for the log. |
Storage Requirement Info:
Over the course of a 85 minute run at an injection rate of 1480, the database storage for database system increased by 1.56 GB. Given a linear scale, a 24 hour run at the same injection rate would increase storage for database system by 26.43 GB. One RAID10 disk array was used to create the filesystem space for the database. The array contained 12 x 146GB disks providing 876 GB of storage. |

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 ?id=128770&coll=portal&dl=ACM&CFID=10343790&CFTOKEN=42047146) |
