PRODCOMM parameter group

Specifies an alternate IP address to bind to.

Specifies an alternate IP address to bind to.

Bypasses outbound data compression.

Specifies the Host: header to generate when sending a client HTTP request, if no Host: header is specified by the caller.

Specifies the Referrer: header to generate when sending a client HTTP request, if no Referrer: header is specified by the caller.

Specifies the User-agent: header to generate when sending a client HTTP request, if no User-agent: header is specified by the caller.

Controls how long (in seconds) the main product address space waits between attempts to connect to any of the TCP/IP subsystems. This field is specified in seconds.

The timeout value for several host operations. The most important use is for Data Virtualization Direct to control how long the host waits for a client TCP/IP (IBM or Interlink) connection to complete. Data Virtualization Web Server uses the value to control how long it waits for each in-bound URL segment to be transmitted. Interlink TCP/IP code also uses this field as the timeout value for directory services requests.

When set to YES, this option causes WWW transaction threads to issue an additional receive just prior to closing an HTTP sessions. This option can be used to correct for an anomalous CRLF, unaccounted for by the “Content-length:” header, which is sometimes sent by Microsoft Internet Explorer browsers. For certain network configurations, closing the session prior to receiving these extra two bytes causes a reset to reach the downstream client before all response data has been received by the client. This appears at the user-agent as a session failure and the downstream client does not read the entire HTTP response. The problem has been seen only with Internet Explorer 5.00.29xxx version Web browsers. The default setting for this option is NO for systems at z/OS Version 1.4. The default is YES for earlier operating systems releases.

Specifies an alternate IP version 6 address to bind to.

Specifies an alternate IP version 6 address to bind to.

Makes the empty buffer not to be sent to the client at the termination of the connection.

Sets the time limit, in seconds, for a response made to a DRDA logon request. If the time limit expires before a response is received, the request is abandoned. The minimum value that can be set is 1 second, and the maximum is 120 seconds.

Sets the port number used to listen for inbound TCP/IP DRDA application requestor sessions. The port is not used if the IDF parameter is set to NO. The minimum value that can be set is 0 and the maximum value that can be set is 65535.

Sets the port number used to listen for inbound SSL TCP/IP DRDA application requestor sessions. The port is not used if the IDF parameter is set to NO. If this parameter is not explicitly set when IDF support is initialized, SSL encryption will not be used for IDF. The minimum value that can be set is 0 and the maximum value that can be set is 65535.

Sets the port number used to listen for, and accept all inbound OE Sockets TCP/IP sessions. This port number should be reserved for exclusive use by the main product address space. Each copy of the main product address space will need its own separate port number if TCP/IP is being used. This port is only used for parallel I/O traffic.

Controls the usage of uncompressed network buffers with variable length rows called CMBVs.

Specifies the fully qualified internet host domain name to be used by a server when constructing fully-qualified HTTP URLs and domain settings. This parameter is used only for OE Sockets TCP/IP Connections.

In a mixed IPv4/IPv6 environment, this parameter specifies the IPv6 host domain name. It is not used unless OEIPV6 is set to YES.

Controls the usage of IPv6 OE sockets calls. If this parameter is set to YES, IPv6 I/O will be used with OE sockets.

Specifies a time limit, in seconds, that Data Virtualization will wait for a response from DRDA after submitting SQL for execution. If no response is received within the specified time, the request is abandoned. The minimum value that may be set is 0 seconds. The maximum is 3600 seconds. If 0 is specified, Data Virtualization does not impose any time limit and will wait until a response is received.

Specifies the time limit, in seconds, that Data Virtualization will wait for a response to a DRDA logon request. If the time limit expires before a response is received, the request is abandoned. The minimum value that may be set is 1 second. The maximum is 120 seconds.

DRDA LOGON MAX FAIL ATTEMPS

The DRDAMAXFAILATTEMPS parameter sets the number of attempts before the IP address of database with DSN is cleared. If the count is set to 0, then clearing of IP is not activated and the IP would not be refreshed. If count it greater than 0 then that many attemps would be made before refreshing the IP.

Determines whether the Data Virtualization Server honors Connection: and Keep-alive: headers for in-bound HTTP/1.0 requests. When set to YES, the Data Virtualization Server attempts to honor in-bound headers which request persistent session support. When set to NO, the Data Virtualization Server ignores such headers for all HTTP/1.0 requests.

Specifies how long to let persistent sessions wait for another HTTP request to arrive on a session kept open for reuse. The value is specified in milliseconds.

Can be set to select the method used to track client IP connection information. When it is not set, the system selects the DEFAULT method and bases the organization upon the NETMODE used by the server. When set to LINK, the server organizes client IP connection information in a linear list and displays it using the ISPF LINKS display panel. When set to TREE, the server organizes client IP connection information in a four-level tree structure, based upon the dot-notation IP address. The information can be displayed using the ISPF IP TREE display panel.

Controls what fraction of the communication buffer should be reserved to allow for buffer overflow. If the field is set to 20, 1/20th of the buffer is reserved. If it is set to 5, 1/5th of the buffer is reserved. This value should be reduced if buffer overflow errors occur.

Controls the size of the buffer used to receive blocks of data from the network. A failure occurs if a client application sends a buffer larger than the maximum size. This value should be raised to allow larger blocks of data to be sent to and from the client.

Minimum Value: 0

Maximum Value: 67108864.

Controls whether Async OE Sockets calls should be used. Async I/O is faster than synchronous I/O. If set to YES, Async I/O is used with OE Sockets. If set to NO, Async I/O is not used with OE Sockets.

Specifies the fully qualified internet host domain name to be used by this Server when constructing fully-qualified HTTP URLs and domain settings. The OEHOSTDOMAIN parameter is used only for OE Sockets TCP/IP connections. This parameter is used for IPV4 connections.

Uses the TCP/IP keep alive facility to detect that a connection is likely no longer valid and force a disconnect. If no data is transferred on a connection in the interval coded here, then the connection is tested and if no response is received, it is disconnected and any resources using it are freed. The smaller the value, the sooner invalid connections are cleaned up. However, the possibility of disconnecting slow connections is greater.

Specifies the maximum length for the connection request queue created by for the LISTEN socket. This value cannot exceed the installation defined maximum that is specified in the SOMAXCONN statement specified in the TCP/IP profile.

Sets the port number used to LISTEN for, and ACCEPT all inbound encrypted OE Sockets TCP/IP sessions. This port number should be reserved for use only by the main product address space. Each copy of the main product address space needs its own port number if SSL over OE Sockets is being used. There is no default value for the SSL port number if the value is not set in the initialization EXEC.

Sets the port number used to LISTEN for, and ACCEPT all inbound OE Sockets TCP/IP sessions. This port number should be reserved for exclusive use by the main product address space. Each copy of the main product address space needs its own separate port number if TCP/IP is being used. There is no default value for this port number if it is not set in the initialization EXEC.

Sets the port number used to LISTEN for, and ACCEPT all inbound encrypted OE Sockets TCP/IP sessions. This port number should be reserved for use only by the main product address space. Each copy of the main product address space needs its own port number if SSL over OE Sockets is being used. There is no default value for the SSL port number if the value is not set in the initialization EXEC.

Indicates the socket linger time (in seconds) for IBM TCP/IP and IBM OE Sockets. If set to zero, socket linger is turned off. If set to a non-zero value, the socket linger is turned on and set for the number of seconds specified by this parameter.

Specifies the port number used to listen for z/Services requests that can be balanced to group members.

Specifies the port number used to listen for all inbound z/Services and Data Virtualization Studio requests.

Specifies the SSL-encrypted HTTP port used to listen for z/Services requests. These requests are not balanced to group members.
