Parameters

**Table 1** JobGateway parameters
Parameter	Description	Default Value
HTTP_INSTANCE_PORT	HTTP port of the JobServer service.	Default value: 29973 Value range: 29970 to 29979
HTTPS_INSTANCE_PORT	HTTPS port of the JobServer service.	Default value: 29972 Value range: 29970 to 29979
JAVA_OPTS	JVM parameter used for garbage collection (GC). Ensure that GC_OPT is correctly set. Otherwise, the process will fail to start.	See the default configuration on the page.
job.record.batch.delete.count	25	Number of aged data records in each batch on JobServers
job.record.expire.count	500000	Number of aged JobServer data records
job.record.expire.day	7	Number of days after which a JobServer job expires
logging.level.org.apache.tomcat	Log level of Tomcat logs on the JobServer server.	Default value: INFO Value range: DEBUG, INFO, WARN, ERROR, or FATAL
root.level	Level of logs on the JobServer server.	Default value: INFO Value range: DEBUG, INFO, WARN, ERROR, or FATAL
NGINX_PORT	Communication port of the JobBalancer service.	Default value: 29970 for HTTPS and 29971 for HTTP Value range: 29970 to 29979
client_body_buffer_size	Buffer size for reading client request body data. If the request body is larger than the buffer, the entire body or only part of it is written to the temporary file.	Default value: 10240 Value range: greater than 0
client_body_timeout	Timeout interval for reading the client request body, in seconds. The timeout is set only for a period of time between two consecutive read operations, not for the transmission of the entire request body. If the client does not transmit any content within this period, the request is terminated and a 408 (request timeout) error occurs.	Default value: 60 Value range: 1 to 86400
client_header_buffer_size	Buffer size for reading client request headers. For most requests, a buffer of 1 KB is sufficient. However, if a request includes long cookies or comes from a WAP client, 1 KB may not be appropriate. If the request line or request header field is not suitable for this buffer, a larger buffer configured by the large_client_header_buffers directive is allocated.	Default value: 1024 Value range: greater than 0
client_header_timeout	Timeout interval for reading the client request header. If the client does not transmit the entire header during this period, the request is terminated and a 408 (request timeout) error occurs.	Default value: 60 Value range: 1 to 86400
client_max_body_size	Maximum size of an HTTP request body, in MB.	Default value: 80 Value range: 1 to 10240
keepalive_requests	Maximum number of requests that can be served through a keepalive connection. After the maximum number of requests is sent, the connection is closed. Closing connections periodically is necessary to free up the memory allocation for each connection. Using a high maximum number of requests may cause excessive memory usage. Therefore, this method is not recommended.	Default value: 1000 Value range: 1 to 100000
keepalive_time	Maximum time during which requests can be processed through one keepalive connection, in seconds. After the time specified by this parameter is reached, the connection is closed after subsequent requests are processed.	Default value: 3600 Value range: 1 to 86400
keepalive_timeout	Timeout during which an idle keepalive connection to an upstream server will stay open. The value 0 disables keepalive client connections.	Default value: 75 Value range: 0 to 86400
large_client_header_buffers.size	Maximum number (large_client_header_buffers.number) and size of buffers used to read large client request headers. A request line cannot exceed the size of one buffer. Otherwise, error 414 (Request-URI Too Large) is returned to the client. A request header field cannot exceed the size of one buffer as well. Otherwise, error 400 (Bad Request) is returned to the client. Buffers are allocated only on demand. These buffers are released if a connection is transitioned into the keepalive state after the request processing is complete.	Default value: 4096 Value range: greater than 0
lb_limit_req_burst	When a large number of requests are sent, the requests that exceed the access frequency limit are stored in the buffer, and error 503 is returned if the requests exceed the buffer size.	Default value: 50 Value range: 1 to 1000
lb_limit_zone_rate	Rate limit on HTTP requests of clients with the same ID, in r/s or r/m. For example, 30r/s indicates that 30 access requests are allowed per second.	Default value: 30r/s Value range: 1 to 100 r/s or 1 to 6000 r/min
lb_limit_zone_size	Size of the HTTP memory buffer, in MB	Default value: 20 Value range: 1 to 10240
lb_req_timeout	Timeout interval for Nginx read/write.	Default value: 60s Value range: 1 to 3600s
proxy_connect_timeout	Timeout interval for setting up a TCP connection with the proxy server. The value is a combination of numbers and units. m indicates minutes and s indicates seconds.	Default value: 3m Value range: 1 to 60 min or 1 to 3600s
proxy_timeout	Timeout between two consecutive read or write operations on a TCP connection to the proxy server. If no data is transmitted within this period, the connection is closed. The value is a combination of numbers and units. m indicates minutes and s indicates seconds.	Default value: 3m Value range: 1 to 60 min or 1 to 3600s
