Abstract

An information processing apparatus accepts migration of data from a migration source information processing apparatus. The information processing apparatus includes a processor to execute an operation for operation target data as a target of a processing request given from a client apparatus when the operation target data is migrated from the migration source information processing apparatus and the processing request is received from the migration source information processing apparatus, and to notify the client apparatus of a processing result of the operation, the result containing arrangement information of the operation target data.

Claims

1. An information processing apparatus to accept migration of data from a migration source information processing apparatus, the information processing apparatus comprising a processor:

to execute an operation for operation target data as a target of a processing request given from a client apparatus when the operation target data is migrated from the migration source information processing apparatus and the processing request is received from the migration source information processing apparatus; and

to notify the client apparatus of a processing result of the operation, the result containing arrangement information of the operation target data.

2. The information processing apparatus according to claim 1, wherein the processor, when the operation target data is currently migrated from the migration source information processing apparatus, executes the operation after completing the migration.

3. The information processing apparatus according to claim 1, wherein the processor, when the operation target data is currently migrated, accepts the migration of the operation target data together with differential data containing an update content of the operation target data in the migration source information processing apparatus, and executes the operation based on the operation target data and the differential data.

4. An information processing apparatus to migrate data to a migration destination information processing apparatus, the information processing apparatus comprising a processor:

to migrate operation target data as a target of a processing request given from a client apparatus to the migration destination information processing apparatus; and

to transmit the processing request to the migration destination information processing apparatus.

5. The information processing apparatus according to claim 4, further comprising a memory to store a record indicating that the operation target data is currently updated when a transaction occurs upon receiving the processing request, and to erase the record upon an end of the transaction.

6. An information processing system comprising:

a migration source information processing apparatus; and

a migration destination information processing apparatus to accept migration of data from the migration source information processing apparatus,

the migration destination information processing apparatus including a processor;

to execute an operation for operation target data as a target of a processing request given from a client apparatus when the operation target data is migrated from the migration source information processing apparatus and the processing request is received from the migration source information processing apparatus; and

to notify the client apparatus of a processing result of the operation, the result containing arrangement information of the operation target data.

7. The information processing system according to claim 6, wherein the migration source information processing apparatus further includes a memory to store a record indicating that the operation target data is currently updated when a transaction occurs upon receiving the processing request, and to erase the record upon an end of the transaction.

8. The information processing system according to claim 6, wherein the client apparatus updates arrangement information of data retained on the client apparatus, based on a result of the operation.

9. The information processing system according to claim 6, wherein when the migration source information processing apparatus configures a cluster system in cooperation with a standby migration source information processing apparatus, the migration destination information processing apparatus synchronizes with a standby migration destination information processing apparatus upon accepting migration of the data.

10. A non-transitory computer-readable recording medium having stored therein a program for causing an information processing apparatus to execute a process comprising:

executing an operation for operation target data as a target of a processing request given from a client apparatus when the operation target data is migrated from the migration source information processing apparatus and the processing request is received from the migration source information processing apparatus; and

notifying the client apparatus of a processing result of the operation, the result containing arrangement information of the operation target data,

wherein the information processing apparatus accepts migration of data from the migration source information processing apparatus.
