retryn

CFTTCP

[RETRYN = {4 | n } ]

Use this field to specify the number of reconnection attempts to make with a time interval of retryw between attempts.

4: default value

  • any other value from 0 to 32767

When retryn attempts have been made without success, Transfer CFT divides retryn by two and multiplies retryw by two and then begins the sequence again up to the total number of times specified retrym.

Example intervals

If retryw = 1, retryn = 4, retrym =12

In this example the following occurs:

  • Four retries at one-minute intervals
  • Two retries at two-minute intervals
  • One retry at four-minute intervals
  • Five retries at eight-minute intervals

Retry concepts

When specifying multiple hosts in CFTTCP and PROTs/SAPs in CFTPART, Transfer CFT first retries the host and then the PROT/SAP.

For example, if RETRYN is set to 1 and there are two defined hosts and two PROTs/SAPs as shown here:

CFTTCP ... HOST = ( 'IP1', 'IP2'),

CFTPART ... PROT = ( 'PROT1', 'PROT2),

           SAP = ( 'SAP1', 'SAP2'),

The retry order is as follows:

  • IP1 SAP1 PROT1 (first host, first protocol)
  • IP1 SAP1 PROT1 (retry)
  • IP2 SAP1 PROT1 (second host, first protocol)
  • IP2 SAP1 PROT1 (retry)
  • IP1 SAP2 PROT2 (first host, second protocol)
  • IP1 SAP2 PROT2 (retry)
  • IP2 SAP2 PROT2 (second host, second protocol)
  • IP2 SAP2 PROT2 (retry)
