7.5.2 Control Parameters
Some parameters have been added to better control the load balancing job management.
Those parameters can be changed in the registry. XTAccess must be re-started in order
to take them into account.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max
Running Jobs (default value = 6): Maximum amount of jobs simultaneously
processed by XTAccess. Once the limit is reached, any additional job will be
“scheduled” (in Jobs_Scheduled” folder) until an “in-progress” job is over.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max IP
Jobs (default value = 6): Maximum amount of jobs simultaneously processed by
XTAccess to or from a given IP address (as destination or source XT server). Once
the limit is reached, any new job involving the same IP address will be “scheduled” (in
Jobs_Scheduled” folder) until a “in-progress” job related to this IP address is over.
Besides, in case a job related to the IP address is in status “Server Busy”, any next
job using the same IP address will stay in “Scheduled” status until all jobs under
“Server Busy” will be passed to “in-progress” status. At that time XTAccess scans the
job list “scheduled” in order to move them to “in-progress” status. In case of XT Copy
job, IP addresses of source and destination XT server are taken into account.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max
XML Jobs (default value = 6): Maximum amount of jobs simultaneously processed by
XTAccess per XML scan folder. This amount defined the maximum amount of XML
files that will be processed by an XML scan folder, possibly after several scan
processes (depending on Max Scan Running Jobs parameter – see below).
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max
XML Jobs Per Scan (default value = 6): Maximum amount of jobs simultaneously
loaded by XTAccess per scan processes. This amount defined the maximum amount
of files that will be loaded by a scan process of the given folder.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\XML
Scan Timeout (default value = 250): Time delay (in milliseconds) between two
successive scan processes, provided that the “Max XML Jobs” parameter is not
already reached.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\XML
Scan Jobs Timeout (default value = 5000): Time delay (in milliseconds) between the
treatment of two successive XML jobs.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\IP
Retry (default value = 12): Maximum amount of attempts to connect to an IP address
of a XT server which does not reply.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\IP
Retry Timeout (default value = 5000): Time delay (in milliseconds) between two
successive attempts to connect to an IP address which does not reply.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\IP
Retry Timeout (default value = 5000): Time delay (in milliseconds) between two
successive attempts to connect to an IP address which does not reply.
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max
Transcoding Jobs (default value = 1): Maximum amount of transcoding jobs
simultaneously processed by XTAccess (rendering of playlists included)
• HKEY_CURRENT_USER\Software\EVS Broadcast Equipment\XTAccess\Max
Meta Jobs (default value = 1): Maximum amount of Meta jobs (Backup of playlist)
simultaneously processed by XTAccess
