Function

Reports connection property information.

Syntax

sa_conn_properties ( [ connection-id ] )

Description

Returns the connection ID as Number, and the PropNum, PropName, PropDescription, and Value for each available connection property. Omitting the connection-id produces results for all connections.

For a listing of available connection properties, see the section “Database properties” in the chapter “Database Performance and Connection Properties” in the Adaptive Server Anywhere Database Administration Guide.

569851433,30,'CacheRead','Cache reads','0'
569851433,31,'DiskRead','Disk reads','57'

569851433,33,'DiskWaitRead','Disk wait for reads','0'
569851433,34,'DiskWaitWrite','Disk wait for writes','0'
569851433,35,'CacheReadTable','Cache table reads','0'
569851433,36,'CacheReadIndLeaf','Cache index leaf reads','0'
569851433,37,'CacheReadIndInt','Cache index interior reads','0'
569851433,38,'DiskReadTable','Disk table reads','0'
569851433,39,'DiskReadIndLeaf','Disk index leaf reads','0'
569851433,40,'DiskReadIndInt','Disk index interior reads','0'
569851433,41,'CacheWrite','Cache writes','0'
569851433,42,'DiskWrite','Disk writes','4'

NoteCacheHits is always reported as 0 by sa_conn_properties, as this information is not stored by user connection. To get cache hit statistics for the entire cache, use sa_eng_properties, and see the output lines for CacheHitsEng, CacheReadEng, and DiskReadEng. If you run the same query on the Catalog Store repeatedly, the first time you should see reads increase but no cache hits; as you repeat the query, cache hits increase in step with cache reads.
