# Maintaining Resend Buffer Definitions

A resend buffer definition defines a resend buffer that can be used by any subscription to expedite the retransmission of a transaction. No resend buffer definitions are required. Resend buffers are defined using the RESENDBUFFER initialization parameter, but should be maintained using the Adabas Event Replicator Subsystem.

PF1/F1 (Help) | Provides you with help for this screen.
PF2/F2 (Repos) | Provides you with a pop-up panel that allows you to specify the name of the definition you want to locate in the list. Once you have specified a name on the pop-up panel and pressed Enter, the list is repositioned so the name you selected appears first. You can use an asterisk as a wild card character at the end of the definition name or partial definition name you specify on the pop-up panel. Or, you can simply enter the first few characters of the name to reposition the list to the first occurrence in the list of a name starting with those characters.
PF3/F3 (Exit) | Returns you to the previous screen.
PF4/F4 (Add) | Allows you to add a new definition. A new screen appears.
PF7/F7 (-) | Allows you to scroll backwards through the list of definitions.
PF8/F8 (+) | Allows you to scroll forwards through the list of definitions.
PF12/F12 (Menu) | Returns you to the main menu.

## Adding Resend Buffer Definitions

3. Fill in the values for the fields on this screen as described below:

   Parameter Name | Description | Default
   --- | --- | ---
   Resend Buffer Name (RESENDBUFFERNAME) | Specify a unique name for the resend buffer definition. The name must use alphanumeric characters and be between one and 8 characters long. There are some constraints on the name. It must: Be comprised of one to eight uppercase, alphanumeric characters and can include the special characters "@", "$", or "#". If the name is less than eight characters, it is automatically padded on the right with blanks. Not begin with a numeric character or a blank. Have no embedded blanks. Not begin with the letters "SYS". | ---
   Resend Buffer Size(RSIZE) | Specify the amount of storage allocated to the buffer. The value must be numeric and specified in units of KB. The default is 32 (32K), and the maximum is 2,097,151 (2,097,151K). If a resend buffer is defined for a subscription that delivers data to multiple destinations, multiple copies of the sent data may be saved, one copy for each destination. The specification of Resend Buffer Size must be large enough to accommodate these multiple copies of the data. | 32

4. Press PF5 to save the resend buffer definition.

## Modifying Resend Buffer Definitions

To use the Adabas Event Replicator Subsystem to modify a resend buffer definition in the Replicator system file:

   The resend buffer definitions are listed on the List of Resend Buffer Definitions screen.

2. Locate the definition you want to modify on the screen and enter an M in the Sel column for that definition.

   You can locate the definition you want in the list by pressing the PF7 (F7) or PF8 (F8) keys to scroll through the list. You can also press PF2 (F2) to specify the name of the definition to which the list should be repositioned.

   An appropriate resend buffer definition screen appears for the resend buffer you selected. For information on modifying this screen, read the description of adding resend buffer definitions in Adding Resend Buffer Definitions.

3. When all modifications have been made, press PF5 to save the changes.

## Copying Resend Buffer Definitions

To use the Adabas Event Replicator Subsystem to copy a resend buffer definition in the Replicator system file:

1. List the resend buffer definitions in the Adabas Event Replicator Subsystem, as described in Listing Resend Buffer Definitions.

   The resend buffer definitions are listed on the List of Resend Buffer Definitions screen.

2. Locate the definition you want to copy on the screen and enter a C in the Sel column for that definition.

   You can locate the definition you want in the list by pressing the PF7 (F7) or PF8 (F8) keys to scroll through the list. You can also press PF2 (F2) to specify the name of the definition to which the list should be repositioned.

   A dialog appears requesting a name for the copy of the resend buffer definition.

        or press PF3 to cancel

3. Specify a new, unique name for the copy of the resend buffer definition and press Enter.

   The resend buffer definition is copied and the copy appears on the List of Resend Buffer Definitions screen.

## Deleting Resend Buffer Definitions

To use the Adabas Event Replicator Subsystem to delete a resend buffer definition in the Replicator system file:

1. List the resend buffer definitions in the Adabas Event Replicator Subsystem, as described in Listing Resend Buffer Definitions.

   The resend buffer definitions are listed on the List of Resend Buffer Definitions screen.

2. Locate the definition you want to delete on the screen and enter a D in the Sel column for that definition.

   You can locate the definition you want in the list by pressing the PF7 (F7) or PF8 (F8) keys to scroll through the list. You can also press PF2 (F2) to specify the name of the definition to which the list should be repositioned.
