Database tuning for Unica Campaign: DB2
A good starting point for tuning your configuration is to use the DB2® AUTOCONFIGURE command. This command generates values for parameters based on your responses to questions about workload characteristics.
Partition databases
In the case of huge data (millions of records), consider partitioning databases and objects.

  - Unica Campaign performance configuration overview
    The purpose of this document is to improve performance of flowchart execution, which is the core of the Unica Campaign application. The performance of Unica Campaign is tied closely to database performance. Optimal settings of database-related parameters can significantly improve overall Unica Campaign application performance.

    - Use database load utilities
      You can improve performance significantly by using a database load utility for all datasources. Database load utilities are available from your database vendors.
    - Spread tablespaces across multiple disks
      A table space is a logical unit of storage in a database. Generally speaking, spreading database table spaces across multiple disks improves performance.
    - Index databases
      In general, the fastest way to access data from a database is to use an index. Indexes increase the efficiency of finding a specific piece of data. Indexing provides an efficient and fast way to identify the data (rows) in a table.
    - Partition databases
      In the case of huge data (millions of records), consider partitioning databases and objects.
    - Partition tables
      Table partitioning can improve performance. Table partitioning is a data organization scheme in which table data is divided across multiple storage objects called data partitions or ranges, according to values in one or more table columns.
    - Perform database maintenance
      For best performance, perform periodic maintenance activity on large tables by running a command such as RUNSTATS.
  - Setting in-database optimization to improve flowchart performance
    Using in-database optimization can improve flowchart performance. When in-database optimization is on, processing is done on the database server and output is stored in temporary tables on the database server whenever possible.
  - Adjusting configuration properties in Unica Campaign to improve performance
    You can adjust configuration properties in Unica Campaign and Unica Platform to improve performance.
  - Troubleshooting Unica Campaign Performance
    Performance depends on many factors, including your database and web server configuration, network connectivity, and Unica Campaign and Unica Platform configuration.

Partition databases

In the case of huge data (millions of records), consider partitioning databases and objects.

The DB2® database manager allows great flexibility in spreading data across multiple database partitions of a partitioned database. You can choose how to distribute your data by declaring distribution keys. To determine which and how many database partitions your table data is spread across, you can select the database partition groups and table spaces where you want to store the data.
