Table 2.1. Pre-defined aliases
| Alias | Value | Notes |
|---|---|---|
| true | kodo.util.CacheMap | The default option. Uses a CacheMap to store compilation data. CacheMap uses a least-recently-used strategy for a fixed number of cache entries, and an optional soft reference map for entries that are moved out of the LRU space. So, for applications that have a monotonically increasing number of distinct queries, this option can be used to ensure that a fixed amount of memory is used by the cache. |
| all | java.util.HashMap | This is the fastest, but compilation data is never dropped from the cache, so if you use a large number of dynamic queries, this option may result in ever-increasing memory usage. Note that if your queries only differ in the values of the parameters, this should not be an issue. |
| false | none | Disables the sharing of compilation data between different query compilations. |

Property name: kodo.RetainValuesInOptimistic
Configuration API: kodo.conf.JDOConfiguration.getRetainValuesInOptimistic
Resource adaptor config-property: RetainValuesInOptimistic
Default: true
Description: If false, then nontransactional objects will be cleared when they are first modified in an optimistic transaction. This cuts down on the possible number of optimistic verification exceptions, but it is not standard JDO behavior and can also have negative performance consequences depending on usage patterns.
Property name: kodo.RetryClassRegistration
Configuration API: kodo.conf.JDOConfiguration.getRetryClassRegistration
Resource adaptor config-property: RetryClassRegistration
Default: false
Description: Controls whether to log a warning and defer registration instead of throwing an exception when a class registered with JDO cannot be fully processed.
