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.
- 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.
