Return (Payload)

    "schemaName" : "Sales",
    "status"     : "LOADED"
    "info"       : "..."


This request performs either a full (re)load of a schema.

On completion, the response contains the status of the operation. Refer to this page for more details about it.

If the load schema has created a backup, the info field is containing the timestamp of the backup.

When using the schemaName parameter, icCube is possibly scanning the content of the /cubes directory (i.e., the deployed schemas) to located the XML definition file (.icc-schema file) containing the schema whose name is given by the request.

If the name of the schema definition file does not follow the icCube format (i.e., derived from the schema name) and having a very large number of schema definition files, it is recommended to use instead the schemaFile parameter.

Use the incrLoad parameter to perform an incremental load of the schema.

Use the keepMdxResultCache parameter to restore the MDX result cache once the incremental load has been performed if required. That is, existing cached requests are re-executed and cached.

Use the forceBackup parameter to force the backup generation even if the schema definition does not mention it. Once loaded, the schema will continue to backup any subsequent activity (e.g., incremental load). Relevant for full load only.

The optional waitS and cancelS parameters allows for cancelling ongoing requests. A lengthy request might prevent the actual load (e.g. incremental load, re-load, etc..) of the schema. Unless specified otherwise loading a schema (or partitions) is performed in two steps. The first step is loading the required data and the second step is actually updating the already loaded schema. The first step can be performed in parallel of ongoing MDX requests but the second step requires no more requests are accessing the schema. Therefore, the load is stuck until all requests are completed. These two parameters allows for cancelling the requests before the second step is performed. Before the second step, icCube waits for waitS seconds, then if it cancels the ongoing requests (if any) and waits for cancelS seconds. Then if there is still some ongoing requests the load fails otherwise icCube proceed with the second step.
