Abstract
An embodiment includes detecting, by a Recovery System, a cache metric where the cache metric comprises a probability of access to a data object for each of a plurality of time segments of a failover log, where the probability of access to the data object for each of the plurality of time segments is based on an access time of the data object contained in the failover log. The embodiment also includes responsive to receiving the cache metric, caching by the Recovery System of the data object based on the cache metric where the data object is cached in a standby cache of the Recovery System.
Claims20
A computer-implemented method comprising:
- detecting, by a Recovery System, a cache metric wherein the cache metric comprises a probability of access to a data object for each of a plurality of time segments of a failover log, wherein the probability of access to the data object for each of the plurality of time segments is based on an access time of the data object contained in the failover log;
- and
- responsive to receiving the cache metric, caching by the Recovery System of the data object based on the cache metric wherein the data object is cached in a standby cache of the Recovery System.
A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a processor to cause the processor to perform operations comprising:
- detecting, by a Recovery System, a cache metric wherein the cache metric comprises a probability of access to a data object for each of a plurality of time segments of a failover log, wherein the probability of access to the data object for each of the plurality of time segments is based on an access time of the data object contained in the failover log;
- and
- responsive to receiving the cache metric, caching by the Recovery System of the data object based on the cache metric wherein the data object is cached in a standby cache of the Recovery System.
A computer system comprising a processor and one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by the processor to cause the processor to perform operations comprising:
- detecting, by a Recovery System, a cache metric wherein the cache metric comprises a probability of access to a data object for each of a plurality of time segments of a failover log, wherein the probability of access to the data object for each of the plurality of time segments is based on an access time of the data object contained in the failover log;
- and
- responsive to receiving the cache metric, caching by the Recovery System of the data object based on the cache metric wherein the data object is cached in a standby cache of the Recovery System.
