IBM DB2 Database Requirements

IBM DB2 Database Requirements

Use the following guidelines when you set up the repository on IBM DB2:
  • If the repository is in an IBM DB2 9.7 database, verify that IBM DB2 Version 9.7 Fix Pack 7 or a later fix pack is installed.
  • On the IBM DB2 instance where you create the database, set the following parameters to ON:
    • DB2_SKIPINSERTED
    • DB2_EVALUNCOMMITTED
    • DB2_SKIPDELETED
    • AUTO_RUNSTATS
  • On the database, set the configuration parameters.
    The following table lists the configuration parameters that you must set:
    Parameter
    Value
    applheapsz
    8192
    appl_ctl_heap_sz
    8192
    logfilsiz
    8000
    maxlocks
    98
    locklist
    50000
    auto_stmt_stats
    ON
  • Set the tablespace pageSize parameter to 32768 bytes.
    In a single-partition database, specify a tablespace that meets the pageSize requirements. If you do not specify a tablespace, the default tablespace must meet the pageSize requirements.
    In a multi-partition database, specify a tablespace that meets the pageSize requirements. Define the tablespace in the catalog partition of the database.
  • Set the NPAGES parameter to at least 5000. The NPAGES parameter determines the number of pages in the tablespace.
  • Verify that the database user has CREATETAB, CONNECT, and BINDADD privileges.
  • Informatica does not support IBM DB2 table aliases for repository tables. Verify that table aliases have not been created for any tables in the database.
  • In the DataDirect Connect for JDBC utility, update the DynamicSections parameter to 3000.
    The default value for DynamicSections is too low for the Informatica repositories. Informatica requires a larger DB2 package than the default. When you set up the DB2 database for the domain configuration repository or a Model repository, you must set the DynamicSections parameter to at least 3000. If the DynamicSections parameter is set to a lower number, you can encounter problems when you install or run Informatica services.
    For more information about updating the DynamicSections parameter, see Updating the DynamicSections Parameter of a DB2 Database.
