Description

The size of FTBL in bytes

FTBL is used for file groups.

  • The minimum value of LFTBL is 4 * nGroup, where nGroup is the value of the NGROUP parameter.
  • The maximum value is 30,473,403
  • In addition to the reserved nGroup bytes in FTBL, each open group requires 62 + 2 * nFilesInGroup, where nFilesInGroup is the number of files in the group.
  • In addition to those storage requirements in FTBL, each group field referenced in a SOUL request requires additional space in FTBL.

Refer to UTABLE: Setting the server size for a discussion of changing the size of LFTBL.
