IBM DB2 Database Requirements

IBM DB2 Database Requirements

Use the following guidelines when you set up the repository on IBM DB2:
  • The database user account that creates the repository must have privileges to perform the following operations:

      ALTER TABLE

      CREATE FUNCTION

      CREATE INDEX

      CREATE PROCEDURE

      CREATE TABLE

      CREATE VIEW

      DROP PROCEDURE

      DROP TABLE

      INSERT INTO

  • The database user that creates the repository must be able to create tablespaces with page sizes of 32 KB.
  • Set up system temporary tablespaces larger than the default page size of 4 KB and update the heap sizes.
    Queries running against tables in tablespaces defined with a page size larger than 4 KB require system temporary tablespaces with a page size larger than 4 KB. If there are no system temporary table spaces defined with a larger page size, the queries can fail. The server displays the following error:
    SQL 1585N A system temporary table space with sufficient page size does not exist. SQLSTATE=54048
    Create system temporary tablespaces with page sizes of 8 KB, 16 KB, and 32 KB. Run the following SQL statements on each database to configure the system temporary tablespaces and update the heap sizes:
    CREATE Bufferpool RBF IMMEDIATE SIZE 1000 PAGESIZE 32 K EXTENDED STORAGE ; CREATE Bufferpool STBF IMMEDIATE SIZE 2000 PAGESIZE 32 K EXTENDED STORAGE ; CREATE REGULAR TABLESPACE REGTS32 PAGESIZE 32 K MANAGED BY SYSTEM USING ('C:\DB2\NODE0000\reg32' ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.33 BUFFERPOOL RBF; CREATE SYSTEM TEMPORARY TABLESPACE TEMP32 PAGESIZE 32 K MANAGED BY SYSTEM USING ('C:\DB2\NODE0000\temp32' ) EXTENTSIZE 16 OVERHEAD 10.5 PREFETCHSIZE 16 TRANSFERRATE 0.33 BUFFERPOOL STBF; GRANT USE OF TABLESPACE REGTS32 TO USER <USERNAME>; UPDATE DB CFG FOR <DB NAME> USING APP_CTL_HEAP_SZ 16384 UPDATE DB CFG FOR <DB NAME> USING APPLHEAPSZ 16384 UPDATE DBM CFG USING QUERY_HEAP_SZ 8000 UPDATE DB CFG FOR <DB NAME> USING LOGPRIMARY 100 UPDATE DB CFG FOR <DB NAME> USING LOGFILSIZ 2000 UPDATE DB CFG FOR <DB NAME> USING LOCKLIST 1000 UPDATE DB CFG FOR <DB NAME> USING DBHEAP 2400 "FORCE APPLICATIONS ALL" DB2STOP DB2START
  • Set the locking parameters to avoid deadlocks when you load metadata into a Metadata Manager repository on IBM DB2.
    The following table lists the locking parameters you can configure:
    Parameter Name
    Value
    IBM DB2 Description
    LOCKLIST
    8192
    Max storage for lock list (4KB)
    MAXLOCKS
    10
    Percent of lock lists per application
    LOCKTIMEOUT
    300
    Lock timeout (sec)
    DLCHKTIME
    10000
    Interval for checking deadlock (ms)
    Also, for IBM DB2 9.7 and earlier, set the DB2_RR_TO_RS parameter to YES to change the read policy from Repeatable Read to Read Stability.
  • 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.
If you use IBM DB2 as a metadata source, the source database has the same configuration requirements.
