Scripts to create the DB are included in the FDA. Table and index initrans were modified. The M_INVENTORY, M_WORKORDER, M_PARTS, O_ORDERLINE tables were horizontally partitioned. Automatic segment space management was used for all tablespaces. System managed undo was used. Table locks were disabled during the run using disable_lock.sql -------------------------------------------------------------------------------- Load Program Modifications: The load program was not modified. BENCHMARK CONFIGURATION INFORMATION -------------------------------------------------------------------------------- Isolation Requirement Info: The following Beans were deployed in READ_COMMITTED mode as per the benchmark requirement: Mfg - AssemblyEnt, BomEnt, ComponentEnt, LargeOrderEnt, PartEnt Orders - ItemEnt Supplier - SupplierCompEnt, SupplierEnt All other beans were deployed using pessimistic locking mode such that all selects including finders are issued with a FOR UPDATE clause in select statement: Corp - CustomerEnt, CustomerInventoryEnt Mfg - InventoryEnt, WorkOrderEnt Orders - OrderEnt, OrderLineEnt Supplier - POEnt, POLineEnt, SComponentEnt Util - SequenceEnt The ItemEnt bean was cached for 20 minute intervals by setting: read-only to true, and time-to-live to 1200000 (ms) in orders-toplink-ejb-jar.xml deployment descriptor. -------------------------------------------------------------------------------- Durability Requirement Info: To ensure database durability, RAID 1 (mirroring) was used for the database Redo logs. Data was laid out on RAID 0 and redolog files were sized to avoid log rollover for the duration of the run. The application server was using mirrored disks to provide durability for server logs and JMS persistence filestore. -------------------------------------------------------------------------------- Storage Requirement Info: An 80 minute run at an injection rate of 4100 increased storage by 10136 MB This extrapolates to 189GB of storage for a 24 hour run. The database is configured with 5697GB of storage. -------------------------------------------------------------------------------- Argument Passing Semantics: Oracle Application Server 10g uses pass-by-value as required by the EJB specification.

Requests were sent to different Appservers using DNS round robin, with the database node acting as the DNS server. The driver used the following jndi.properties: java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory java.naming.provider.url=ormi://main.specj.com:23791/SPECjAppServer java.naming.security.principal=oc4jadmin java.naming.security.credentials=welcome oracle.j2ee.rmi.loadBalance=lookup -------------------------------------------------------------------------------- General Notes -------------------------------------------------------------------------------- The only errors in the driver error logs are the application errors generated by this benchmark. Two Database checkpoints during the Measurement Interval were done by using the Oracle SQLPlus command: alter system checkpoint Oracle Application Server 10g Release 10.1.3.2 implements Recoverable Last Resource Commit (RLRC) optimization where one and only one SinglePhaseResource participates in a global transaction with one or more XAResources. This is accomplished by emulating an XAResource to represent the 1PC resource. The transaction manager takes the following steps when it receives a request to commit a global transaction that includes one emulated XAResource: 1. It invokes a prepare call on each of the 2PC resources. 2. If all of the 2PC resources are successfully prepared, then commit (one-phase) is called and the commit record is written to the commit-log, on the emulated XA resource (database) as part of the local transaction. 3. If the 1PC on the emulated XA resource completes successfully, then the transaction manager calls commit on each of the 2PC resources. or: If the 1PC on the emulated XA resource fails, then the transaction manager queries the commit-log for transaction outcome. If the record exists, 2PC resources are committed, otherwise 2PC Resources are aborted. Transaction outcome after a single point of failure is guaranteed by the presence of the commit-record in the commit log, indicating a successful transaction completion; while a missing commit-record signifies abort. The commit record is deleted lazily after the global transaction has committed. In conjunction with the RLRC implementation, the log-file location specified in the transaction-manager.xml identifies the location where the participating resource managers are recorded. The commit record table name associated with an instance is specified in the commit-record-table-name attribute, in the Connection-Factory element of data-sources.xml. -------------------------------------------------------------------------------- For questions about this result, please contact the submitter: Oracle Corporation For other inquiries, please contact SPEC - Benchmark run on Tue Nov 21 04:22:46 PST 2006 by SPECjAppServer2004 v1.06 - Result submitted on Wed Nov 22 03:03:00 EST 2006 - Report generated by SPECjAppServer2004 Reporter v1.03 Copyright (C) 2004 Standard Performance Evaluation Corporation
