Monitor Usage of a Cache Administration User Tablespace

To monitor the cache administration user tablespace, you can use either Oracle Enterprise Manager alerts or set the TimesTen tablespace threshold parameter.

The cache agent can be configured to periodically monitor the tablespace usage and issue a warning when it exceeds a specified threshold. Set the tablespace threshold percentage with the TblspaceThreshold parameter of the ttCacheConfig built-in procedure. For example, if you set the TblspaceThreshold parameter to 80, then a warning is issued when more than 80% of the tablespace is used.

• If the threshold is set to zero, then no warning is issued. This is the default.

• If the threshold is set between 1 and 99, a warning is issued when the tablespace threshold exceeds that number.

• If the threshold is set to 100, then a warning is issued when the tablespace is full.

For example, to configure for a warning to be issued if the tablespace exceeds 80%, execute the following:

call ttCacheConfig('TblspaceThreshold',,,'80');

For full details of the ttCacheConfig built-in procedure, see the ttCacheConfig in the Oracle TimesTen In-Memory Database Reference.
