![]() ![]() Methods inherited from class Oracle, DECODE function allows us to add procedural if-then-else logic to the query. Visit the package summary of the oracle.kv.coherence package for how toĬonfigure a NoSQL backed cache with Coherence 3.7.1. Recommended for you to upgrade to the latest version of Coherence. ![]() You may use this module with Coherence version 3.7.1, however it's highly Here is an example for the configuration of an Oracle Coherence cache using Valid values are as shown forĭurability-replica-ack - (Optional) Specifies the DurabilityĬompleteness for replica nodes. Valid values are:ĭurability-replica-sync - (Optional) Specifies the DurabilityĬompleteness for writes at replica nodes. Time durations can be specified using standardĭurability-master-sync - (Optional) Specifies the DurabilityĬompleteness for writes at the master replication node. 1ns, 1us, 1ms, 1s)Ĭonsistency-timeout - (Optional) Specifies the timeout for waitingįor consistency. Oracle Coherence time unit suffixes (e.g. Time durations can be specified using standard TIME - requires consistencyTimeLag and consistencyTimeoutĬonsistency-time-lag - (Optional) Specifies the maximum time lagįor valid consistency.Is not valid in conjunction with keyPrefix.Ĭonsistency - (Optional) Specifies the type of consistency to use Rules for mapping Coherence cache keys to Oracle NoSQL Database keys. Which implements the CacheKeyMapper interface. Key-mapper - (Optional) Names a class with a no-arg constructor and Key path components to prepend to any key passed to the cache store Specified must begin with a '/' character and indicates zero or more major Valid in conjunction with the keyMapper option. Key-prefix - (Optional) A prefix to apply to relative keys. Values that serve as the gateway to the Oracle NoSQL Database instance. Helper-hosts - (Required) A comma-separated list of helperHost:port Is used to provide persistence for your Oracle Coherence cache. Store-name - (Required) The Oracle NoSQL Database instance name that The various configuration parameters to adjust the behavior to yourĪpplication's specific requirements are set within the cache definition XML In addition to the basic information needed to connect to theĭatabase, a number of additional store interaction properties are alsoĬonfigurable, allowing the developer to set Durability, Consistency The NoSQLBinaryStore also needs to access a Oracle NoSQL Database The Oracle Coherence value objects can be of any type, provided they can be If an application needs greater control over the way in which OracleĬoherence keys are mapped to Oracle NoSQL Database Key objects, theĬache can be configured with a key-mapper, which can provideĪrbitrary translation of key types. Major path component if key-prefix was not specified. In the key-prefix option, if specified, or as the single top-level The result is treated as a single path component relative to the components For all other object types, the serializedįorm of the object is encoded using the encodeBinaryKey(byte) method, and Key, the objects are used directly as the Oracle NoSQL Database Handled differently, depending on the the type. Specified, the cache key objects can be any object type, but the keys are In the default mode of operation, where no key-mapper has been Require converting the Oracle Coherence application's representation of aĬache key and a cache value into a form that meets the needs of OracleĪ BinaryEntryStore relies on the Coherence application for serialization and Is not present, to store data when changes are made to the cache, and toĭelete a KV entry when a remove is performed on the cache. This implementation handles requests to load data into the cache when a key NoSQLBinaryStore is aīinaryEntryStore, which implies that the cache must be defined as In order to use the NoSQLBinaryStore module, you must configureĪn Oracle Coherence cache to use it. However, this class does define two staticįunctions, which provide access to the key encode/decode logic, if needed. Theĭocumentation contained in this class is intended primarily to explain the Result of XML configuration supplied to Coherence at program startup. It is expected that the class is managed by Oracle Coherence as the Users are not generally expected to directly interact with instances of thisĬlass. To deal with single operation and bulk operations that have been requested This implementation uses a single Oracle NoSQL Database handler Oracle NoSQL Database implementation of the BinaryEntryStore ![]()
