Troubleshooting: Importing studies from CD or DVD is slow

Issue

The process of importing studies from CD or DVD is slow.

Details

To improve performance, increase the ASPFTP process number from 128 to 512.

Solution

To increase the ASPFTP process number from 128 to 512

1. Log into the AS300 or AS3000 Database Server as the mvf user.

2. Launch CLUI.

3. To increase the ASPFTP process number, type

   UPDATE map_service SET concurrency=512 WHERE port=3040

4. Only on the AS3000 Database Server, type commit.

5. To exit CLUI, type exit.

6. To restart the ASPFTP process on the AS300 Database Server:

   1. Select Start > Run.

   2. In the Open field, type services.msc.

   3. Select DICOM Authenticated Storage Cache Server and click Restart.

7. To restart the ASPFTP process on the AS3000 Database Server:

   1. To obtain the ASPFTP process ID, at a terminal window, type ps -ef | grep mvf-aspftpd.

   2. Note the process ID number displayed.

   3. To stop the process, type kill process_id where process_id is the process ID number noted in step b.

      The ASPFTP process is started automatically.

Note: The CD or DVD import process stops when the IMPAX Client automatically logs you out. If you are importing many large studies, we recommend disabling automatic logout or extending the automatic logout idle time to ensure all studies are imported. For details, see “Setting an automatic logout time” (topic number 9393) in the IMPAX 6.5.1 Client Knowledge Base: Extended.
