The parameters listed below control the gateway resources: These include number of external connections, memory consumption, and so on.

Features

gw/max_sys

Specifies the maximum number of clients connected at a time. Note that the gateway regards an SAP application server as one single client.

Default Value

300

Unit

Integer (maximum 4096)

Dynamic

No

gw/max_conn

Specifies the maximum number of connections that can be active at a time.

Default Value

500

Unit

Integer (maximum 4096)

Dynamic

No

gw/listen_queue_len

The operating system must keep requests in a queue while the connection is being set up. This parameter specifies the maximum number of requests than can have this status at any one time. If the network queue is full, the system rejects any additional connection requests without notifying the sender.

Default Value

512

Unit

Whole number (between 5 and 1024)

Dynamic

No

gw/max_overflow_usage

Specifies the usage of the overflow area as a percentage from which the gateway slows down its clients, that is it sends SYNC requests. .

Default Value

20

Unit

Percentage

Dynamic

Yes

gw/max_overflow_size

This parameter specifies the size of the overflow area in bytes. The gateway allocates local process memory for this overflow area.

Default Value

10000000 (10MB)

Unit

Bytes (Value between 1000000 and 99900000)

Dynamic

Yes

If many clients send their data faster than the receivers can accept it, you can increase the value of this parameter. As the gateway allocates local process memory, only more swap space is required. Approximately 200 KB is required for each client that sends data quickly.

gw/req_stack_size

This parameter specifies the number of CICP requests that can be stacked for each CPIC connection.

Default Value

30

Unit

Whole number (between 5 and 300)

Dynamic

Yes

If many clients send their data faster than the receivers can accept it, you can increase the value of this parameter. If you increase the value, more requests can be stacked in the gateway before the data is synchronized with the partner.
