CkptLogVolume
Controls the amount of data in megabytes that collects in the log between
background checkpoints. The counter used for the checkpoint condition is reset
at the beginning of each checkpoint.
If both CkptFrequency and CkptLogVolume attributes are specified, a checkpoint
is performed when either of the two conditions becomes true. The values set by
the ttCkptConfig built-in procedure replace the values set by these attributes.
In the case that your application attempts to perform a checkpoint operation
while a background checkpoint is in process, TimesTen waits until the
background checkpoint finishes and then executes the application’s checkpoint.
To turn off background checkpointing, set CkptFrequency=0 and
CkptLogVolume=0.
The setting of this attribute is “sticky:” it can only be changed by using an
explicit value. The default value is only used during data store creation.
Subsequent first connections default to using the existing value stored in the data
store. If left unspecified (or empty in the Windows ODBC Data Source
Administrator), the stored setting is used. To turn the attribute off, you must
explicitly specify a value of 0.
If Access Control is enabled, this attribute requires ADMIN privileges.
Setting Set CkptLogVolume as follows:
C or Java
programs
or UNIX
ODBC.INI file
Windows
ODBC Data
Source
Administrator
CkptLogVolume Specify the amount of data that an
accumulate in the log file between
background checkpoints. The default
is 64 if Logging=1 is specified,
otherwise it is 0. To specify the
default or “existing” value, leave the
value empty. A value of 0 means that
log volume is not considered when
scheduling checkpoints.
CkptLogVolume
field
Specify the amount of data that an
accumulate in the log file between
background checkpoints. The default
is 64 if Logging=1 is specified,
otherwise it is 0. To specify the
default or “existing” value, leave the
field empty. A value of 0 means that
log volume is not considered when
scheduling checkpoints.
