Summarizes communication compression rates.
sa_conn_compression_info( [ connidparm ] )
connidparm Use this optional INTEGER parameter to specify the ID number of a connection.
|Column name||Data type||Description|
|Type||VARCHAR(20)||A string identifying whether the compression statistics that follow represent either one Connection, or all connections to the Server.|
|ConnNumber||INTEGER||An INTEGER representing a connection ID. Returns NULL if the Type is Server.|
|Compression||VARCHAR(10)||A string representing whether or not compression is enabled for the connection. Returns NULL if Type is Server, or ON/OFF if Type is Connection.|
|TotalBytes||INTEGER||An INTEGER representing the total number of actual bytes both sent and received.|
|TotalBytesUnComp||INTEGER||An INTEGER representing the number of bytes that would have been sent and received if compression was disabled.|
|CompRate||NUMERIC(5,2)||A NUMERIC (5,2) representing the overall compression rate. For example, a value of 0 indicates that no compression occurred. A value of 75 indicates that the data was compressed by 75%, or down to one quarter of its original size.|
|CompRateSent||NUMERIC(5,2)||A NUMERIC (5,2) representing the compression rate for data sent to the client.|
|CompRateReceived||NUMERIC(5,2)||A NUMERIC (5,2) representing the compression rate for data received from the client.|
|TotalPackets||INTEGER||An INTEGER representing the total number of actual packets both sent and received.|
|TotalPacketsUnComp||INTEGER||An INTEGER representing the total number of packets that would have been sent and received if compression was disabled.|
|CompPktRate||NUMERIC(5,2)||A NUMERIC (5,2) representing the overall compression rate of packets.|
|CompPktRateSent||NUMERIC(5,2)||A NUMERIC (5,2) representing the compression rate of packets sent to the client.|
|CompPktRateReceived||NUMERIC(5,2)||A NUMERIC (5,2) representing the compression rate of packets received from the client.|
If you specify the connection ID number, the sa_conn_compression_info system procedure returns a result set consisting of compression properties for the supplied connection. If no connection-id is supplied, this system procedure returns information for all current connections to databases on the server.
For information about the properties these values are derived from, see Connection-level properties.
The following example uses the sa_conn_compression_info system procedure to return a result set summarizing compression properties for all connections to the server.
CALL sa_conn_compression_info( );
