.SH DESCRIPTION
|
||
|
|
\fBDB_ENV->set_cachesize\fr sets the size of the shared-memory buffer
|
||
|
|
pool (the cache) to \fIgbytes\fR* gibibytes plus \fIbytes\fR bytes.
|
||
|
|
|
||
|
|
.SH PARAMETERS
|
||
|
|
.IP \fIdbenv
|
||
|
|
The environment (which must have been created but not yet opened).
|
||
|
|
|
||
|
|
The environment is modified, not just this particular handle. If some
|
||
|
|
other thread or process has opened the same environment, then this call
|
||
|
|
is ignored.
|
||
|
|
.IP \fIgbytes
|
||
|
|
The number of gibibytes (gibi equals 2^30, giga equals 10^9) to allocate.
|
||
|
|
.IP \fIbytes
|
||
|
|
The number of additional bytes to allocate.
|
||
|
|
.IP \fIncache
|
||
|
|
Ignored in TokuDB.
|
||
|
|
.SH RETURN VALUE
|
||
|
|
.LP
|
||
|
|
Returns zero on success. The following non-zero errors can be returned:
|
||
|
|
.IP \fBEINVAL
|
||
|
|
You passed invalid parameters to this operation. In many cases
|
||
|
|
\fBEINVAL\fR
|
||
|
|
is not a very helpful error code, indicating only that you did something wrong.
|
||
|
|
.SH CONFORMING TO
|
||
|
|
The TokuDB embedded database provides a subset of the functionality of
|
||
|
|
the Berkeley DB. Programs that work with TokuDB probably work with
|
||
|
|
with most versions of Berkeley DB with only recompilation or
|
||
|
|
relinking. The database files are incompatible, however, so to
|
||
|
|
convert from one library to the other you would need to dump the
|
||
|
|
database with one library's tool and load it with the other's.
