How You Configure the DAS

To configure the DAS, use the DAS Parameters page in Configuration Manager (vcbf) or the Configuration-By-Forms (cbf) utility.

DAS Parameters—Configure DAS

The DAS has the following configurable parameters:

• client_max

  Defines the maximum number of concurrent client connections permitted.
  Set to –1 for no limit.

• client_timeout

  Defines the time, in minutes, to wait for client requests. If the time expires with no request from the client, the client and DBMS Server connections are aborted.
  Set to 0 for no timeout.

• connect_pool_expire

  Defines the time, in minutes, for which a DBMS Server connection remains in the connection pool. The connection is aborted if a pooled connection is not used in this amount of time.
  Set to 0 for no expiration.

• connect_pool_size

  Defines the maximum number of DBMS Server connections held in the connection pool.
  Set to –1 for no limit.

• connect_pool_status

  Specifies the operational mode of the connection pool. Modes are:

  • on

    Enables pooling unless explicitly disabled by the client. The DAS saves and reuses DBMS Server connections when connection pooling is enabled.

  • off

    Disables pooling.

  • optional

    Enables pooling but only when requested by the client.

• <protocol>.port

  Identifies the listen address for the network protocol port. This can be a numeric port identifier or an Ingres symbol port identifier such as II7. This port must not be used by any other network server on the platform.

• <protocol>.status

  Specifies the status of the network protocol. Options are:

  • on

    Indicates that the DAS must listen/accept connection requests on the protocol.

  • off

    Disables the protocol.
