TRIRIGA recommends that the database server be co-located on the same subnet as the application and process servers. Licensing For this reason, cloud database offerings such as Oracle’s Database Cloud Exadata Service are not recommended for adequate performance. However, hosting the entire TRIRIGA infrastructure in the cloud where the TRIRIGA Object Labels and R… infrastructure is hosted on the same subnet is a viable configuration for good performance. In addition, customers have Offlining reported good performance using Oracle’s Exadata Database Machine in on-premise deployments. Always check the IBM TRIRIGA Support and Compatibility Matrix for the latest database versions and fix packs OSLC supported. Performance issues where the database server is not co-located with the application and process servers are not supported.

DB2 database PARALLEL_DEGREE_POLICY specifies whether automatic degree of parallelism, statement queuing, and in-memory parallel execution will be enabled. The default of MANUAL can be changed to ADAPTIVE. Oracle database Increase the process number to handle more concurrent users by setting the PROCESSES= initialization parameter to the Microsoft SQL … maximum number of users who can access Oracle concurrently. A general guideline is to add up all maximum JDBC connection pool values from each JVM and add another 100 for Oracle. For example, adding an application server (200), Application Serve… plus process server (200), plus Oracle (100), would require a PROCESSES value of at least 500. IBM TRIRIGA tuni… In Oracle 11g and 12c, automatic memory management allows for automatically readjusting the sizes of the main pools (db_cache_size, shared_pool_size, large_pool_size, and java_pool_size) based on existing workloads.

Oracle RAC Considerations Performance Degra… DB2 Database Sho… Many customers think that many smaller nodes in a Real Application Clusters (RAC) configuration will yield better performance. This configuration may be fine for high availability, but small system-based RAC is not the best solution for performance, and Platform Logging overall, ends up hurting performance. To scale Oracle for performance, the solution is vertical scalability, that is, adding CPU, RAM, and disk to the individual nodes. Many performance issues are the result of environmental configuration and the choice to Portal and Navigation use smaller servers versus bigger ones. Reporting RAC requires more resources because it must maintain the cluster state across all the nodes, as well as serve the data out to the applications. With resources consumed by the "busy work" to maintain the cluster, each node is less powerful than if it were Reserve in a single instance. RAC is good for being highly available, but at a great cost of maintainability and individual system resources. The nodes must be vertically scaled to handle the load of the requests from the application tier. But adding nodes horizontally Scheduler Engine (S… will only slow down the environment. Security SSO 5.4.2 Oracle Application Platform Indexes Styling The following performance tuning indexes can be added to Oracle databases that are running TRIRIGA Platform 3.5.x. These System Sizing recommended Oracle performance tuning indexes are the result of iterative performance tuning cycles and collaboration with the TRIRIGA development team. The indexes listed here are not included in the TRIRIGA base product unless otherwise stated. TDI These indexes provide significant performance improvements when measured against a broad performance test workload. While Web Graphics TRIRIGA recommends adding these indexes to the Oracle database platform, performance gains might vary depending on an array of factors including application usage, load patterns, hardware sizing, application, database server configuration, and so Workflow on. Oracle database administrators should monitor databases for efficient index usage to determine the overall impact produced by applying the recommended indexes, and to determine additional indexes that will improve performance based on situational Release Notes and data composition needs.
