What Is the Dispatcher Paragon Spooler Controller Cache?

The Dispatcher Paragon Spooler Controller cache is the persistent storage on the Dispatcher Paragon Spooler Controller server. Dispatcher Paragon Spooler Controller saves all necessary data to the cache so that it can run in offline mode (without connection to Dispatcher Paragon Management Server) and optimize the data flow between Dispatcher Paragon Spooler Controller and Dispatcher Paragon Management Server. The cache contains, for example, the print job metadata, billing codes, users, devices, and so on. Most of the entities stored in the cache are downloaded from Dispatcher Paragon Management Server during the Dispatcher Paragon Spooler Controller's startup. The others (e.g., users) are downloaded when needed.

About Dispatcher Paragon Spooler Controller Cache Deletion

Deleting the Dispatcher Paragon Spooler Controller cache is, in specific cases, the only way to restore proper Dispatcher Paragon Spooler Controller functionality.

When the cache is deleted, the particular Dispatcher Paragon Spooler Controller will lose all information about users, cards, jobs, billing codes, and printers etc.

  • All necessary information about printers, users rights, and billing codes are synchronized again to the Dispatcher Paragon Spooler Controller (from Dispatcher Paragon Management Server) during the first synchronization (after the restart of Dispatcher Paragon Spooler Controller services).
  • Information about print jobs is synchronized as part of the cache recovery mechanism, where Dispatcher Paragon Spooler Controller downloads all its jobs from Dispatcher Paragon Management Server and saves them to the cache.
  • The user's data will be synchronized to Dispatcher Paragon Spooler Controller (from Dispatcher Paragon Management Server) during the first authentication of the user or when the user sends a print job to Dispatcher Paragon that will be accepted by a particular Dispatcher Paragon Spooler Controller.

WARNING

The Dispatcher Paragon Spooler Controller cache is almost equal to the Dispatcher Paragon Management Server database. The request for the deletion of the Dispatcher Paragon Spooler Controller cache will be performed only when requested by Konica Minolta or when it is explicitly defined in the manual.

The Dispatcher Paragon Spooler Controller cache recovery mechanism on a standalone SPOC with the recommended hardware is processing on average 3000 jobs per minute. That means with 60 000 jobs the recovery will take about 20 minutes. SPOC is not fully functional until the recovery is finished. To see how many jobs is going to be recovered use the following SQL query:

-- query to be launched on SQDB6 database
-- use proper tenant prefix at smartq_jobs table
-- use proper server_guid, SPOC guid can be found on Dispatcher Paragon management interface -> tab Spooler Controller groups
SELECT count(1) FROM tenant_1.smartq_jobs where server_guid = 'j1dvczklt5l5hm69' and cur_status in (1,2,4,8,16,32,64,128,256,512)
