EssListRequests

Description

EssListRequests() returns information about sessions and requests in progress, terminated, or in the process of being terminated.

Syntax

ESS_FUNC_M EssListRequests (hCtx, UserName, AppName, DbName, RequestCount, pRequestInfo);
ESS_HCTX_T hCtx
ESS_STR_T UserName
ESS_STR_T AppName
ESS_STR_T DbName
ESS_PUSHORT_T RequestCount
ESS_PPREQUESTINFO_T ppRequestInfoStruct

Parameters

hCtx Essbase API context handle.
pDdbCtx Distributed database context to be filled.

Return Value

Returns zero if successful; error code if unsuccessful.

Notes

EssListRequests() returns information about sessions and requests in progress, terminated, or in the process of being terminated.

A session is the time in seconds between an Essbase user's login and logout.

A request is a query sent to Essbase by a user or by another process; for example, starting an application, or restructuring a database outline. Each session can process only one request at a time; therefore, sessions and requests have a one-to-one relationship.

This function returns information on requests/sessions initiated by the process specified by the UserName, AppName, and DbName. If these parameters are null or empty, then all the processes in the system are listed. This function returns the number of current, terminating, and terminated requests and one ESS_REQUESTINFO_T structure for each request.

The returned ppRequestInfoStruct needs to be freed by calling EssFree.
