Parameters Removed or Deprecated

RootDirectory
LegacyHash
OldSetClauseSemantics
OldColumnNaming
LockGrantOrder
Obsolete Windows priority settings

The following parameters have been removed or deprecated:

RootDirectory

In older version, this parameter provided a superfluous option for recording the file system path to Firebird's “root” files (firebird.conf, the security database and so on).

LegacyHash

This parameter used to make it possible to use the old security.fdb from Firebird 1.X installations after it had been subjected to an upgrade script and thence to enable or disable use of the obsolete DES hash encrypting algorithm. It is no longer supported.

OldSetClauseSemantics

This parameter enabled temporary support for an implementation fault in certain sequences of SET clauses in versions of Firebird prior to v.2.5. It is no longer available.

OldColumnNaming

This parameter temporarily enabled legacy code support for an old InterBase/Firebird 1.0 bug that generated unnamed columns for computed output which was not explicitly aliased in the SELECT specification. It is no longer available.

LockGrantOrder

This parameter used to allow the option to have Firebird's Lock Manager emulate InterBase v3.3 lock allocation behaviour, whereby locks would be granted in no particular order, as soon as soon as they were available, rather than by the normal order (first-come, first-served). The legacy option is no longer supported.

Obsolete Windows priority settings

UsePriorityScheduler, PrioritySwitchDelay and PriorityBoost, which were marginally relevant to obsolete processors on obsolete Windows versions, are no longer supported.
