Restrictions for a Dynamic Hybrid Read-Only Cache Group

Restrictions for using a dynamic hybrid read-only cache group.

The following are restrictions for a dynamic hybrid read-only cache group:

  • You can execute a SELECT statement on the root table, as this may help in diagnosing problems. However, a dynamic load is not triggered if you execute a SELECT on the root table in TimesTen.

  • Hybrid cache groups do not support manually loading the cache group with the LOAD CACHE GROUP statement.

  • LRU aging is on by default for dynamic cache groups, including hybrid cache groups. Currently, time-based aging is not supported for hybrid cache groups.

  • Currently, the WHERE clause is not supported in CREATE CACHE GROUP for hybrid cache groups.

  • Currently, the WITH ID clause is not supported in UNLOAD CACHE GROUP for hybrid cache groups.
