This parameter specifies the interval of time (in seconds) for which the generated file access control token is valid. The number of seconds the token is valid begins from the time it is generated. The Data Links Filesystem Filter checks the validity of the token against this expiry time.
For information about file access control tokens, refer to the DB2 Data Links Manager Quick Beginnings book.
The default value for this parameter is sixty (60) seconds. Minus one (-1) implies that the token will effectively not expire.
This parameter applies to the DATALINK columns that specify "READ PERMISSION DB".
