Abstract

Embodiments for server connection optimization in a persistently connected publish/subscribe environment are provided. A computer assigns an initial activity category for a client. The computer logs, into a log file, one or more select operations of a connection between a client and a first server. The computer calculates a ratio of a number of the select operations to a check time of the first server, wherein the check time is a period of time that has elapsed since a previous review of logged data. The computer sets a second activity category for the client based on a look-up of the ratio in a schedule of ratio ranges in a control file, wherein the second activity category is not the initial activity category. The computer transfers the client from the first server to a second server, in response to setting the second activity category.

Claims

1. A data processing system for managing server connections between client computers and servers, the data processing system comprising:

one or more processors, one or more computer-readable memories and one or more computer-readable, storage devices, and program instructions stored on the one or more storage devices for execution by the one or more processors via the one or more memories, the program instructions comprising;

program instructions to assign an initial server-activity category for a first client computer;

program instructions to log one or more select operations requested by the first client computer to a first server;

program instructions to calculate a ratio of a number of the one or more select operations to a predetermined period of time during which the one or more select operations were logged; and

program instructions to replace the assignment of the initial server-activity category with a second, different, server-activity category for the first client computer based on the ratio, and in response, transfer the first client computer from the first server to a second server to process subsequent requests by the first client computer, wherein the second server-activity category is a middle server-activity category having a corresponding middle ratio range, the initial server-activity category having a corresponding initial ratio range covering a range higher than the middle ratio range;

and wherein a third server-activity category having a corresponding third ratio range, the third ratio range covering a range lower than the middle ratio range, wherein the second server-activity category is a middle server-activity category comprising a ratio range an upper threshold of, at most, ten select operations per 60 seconds.

2. The data processing system product of claim 1, further comprising, program instructions to place a received message from the first client computer in a queue with other messages such that the messages are processed in a first interval shorter than a second interval used with client computers assigned to the initial server-activity category, responsive to replacing the assignment of the first client computer to the second server-activity category.

3. A computer program product for managing server connections between clients and servers, the computer program product comprising:

a computer readable storage device having program instructions stored thereon, the program instructions comprising;

program instructions to assign an initial server-activity category for a first client computer;

program instructions to log one or more select operations requested by the first client computer to a first server;

program instructions to calculate a ratio of a number of the one or more select operations to a predetermined period of time during which the one or more select operations were logged; and

program instructions to replace the assignment of the initial server-activity category with a second, different, server-activity category for the first client computer based on the ratio, and in response, transfer the first client computer from the first server to a second server to process subsequent requests by the first client computer, wherein the second server-activity category is a middle server-activity category having a corresponding middle ratio range, the initial server-activity category having a corresponding initial ratio range covering a range higher than the middle ratio range;

and wherein a third server-activity category having a corresponding third ratio range, the third ratio range covering a range lower than the middle ratio range, wherein the second server-activity category is a middle server-activity category comprising a ratio range an upper threshold of, at most, ten select operations per 60 seconds.

4. The computer program product of claim 3, further comprising, program instructions to place a received message from the first client computer in a queue with other messages such that the messages are processed in a first interval shorter than a second interval used with client computers assigned to the initial server-activity category, responsive to replacing the assignment of the first client computer to the second server-activity category.

5. A method for managing server connections between clients and servers, the data method comprising:

a server assigning an initial server-activity category for a first client computer;

the server logging one or more select operations requested by the first client computer to a first server;

the server calculating a ratio of a number of the one or more select operations to a predetermined period of time during which the one or more select operations were logged; and

the server replacing the assignment of the initial server-activity category with a second, different, server-activity category for the first client computer based on the ratio, and in response, transferring the first client computer from the first server to a second server to process subsequent requests by the first client computer, wherein the second server-activity category is a middle server-activity category having a corresponding middle ratio range, the initial server-activity category having a corresponding initial ratio range covering a range higher than the middle ratio range; and

wherein a third server-activity category having a corresponding third ratio range, the third ratio range covering a range lower than the middle ratio range, wherein the second server-activity category is a middle server-activity category comprising a ratio range an upper threshold of, at most, ten select operations per 60 seconds.

6. The method product of claim 5, further comprising, responsive to replacing the assignment of the first client computer to the second server-activity category, placing a received message from the first client computer in a queue with other messages such that the messages are processed in a first interval shorter than a second interval used with client computers assigned to the initial server-activity category.
