IM-common master batch job cannot be carried out with the error message of “this export is already started.” when I try to execute it, although the same batch job is not being multi-run.

 
[Target products]
A.intra-mart WebPlatform Version7.2x
B.intra-mart Accel Platform All versions

This error is caused by the import/export simultaneous-execution prevention function for IM-common master import batch jobs.
There is the locking function for IM-common master import/export batch jobs not to be executed simultaneously. 
A simultaneous-execution control file is created when import/export is started.

For A.intra-mart WebPlatform Version7.2x
[A path of a created control file]
------------------------------------------------------
StorageService/master/%login group code%/batch/%data area%/%processing name%
------------------------------------------------------
For B.intra-mart Accel Platform
[A path of a created control file]
------------------------------------------------------
%PUBLIC_STORAGE%/im_master/lock/%tenant ID%/%data area%/%processing name%
------------------------------------------------------

Import/export is started if a control file does not exist at the timing of starting. If it already exists, however, the system judges it to be simultaneous execution and does not execute import/export. The processing ends after “this export is already started.” is output to the log.
Start control files are usually to be deleted after batch job processing completion. In the case where batch job processing is suddenly terminated for any failure, however, a control file remains as it is.
When there remains a control file, the system judges it to be simultaneous execution and the error “this export is already started.” occurs even though the same batch job is not being multi-run.

[Handling methods]
Manually delete a control file created in the above file of [A path of a created control file].
