Description
With getSessionCount method, you can get the following three types of information.
-
The total number of active sessions opened for the specified application in the specified Appeon Server.
-
The total number of active sessions in a specified Appeon Server.
-
The total number of sessions opened for the specified application in an Appeon Server cluster. To get the number of sessions in an Appeon Server cluster, you need to first configure the cluster in AEM.
Usage
By using the getSessionCount method, you can easily get the total number of active sessions in a specified Appeon Server using PowerBuilder code and apply the information in other open interfaces, such as KillSession, to manage the sessions. For example, you can first call getSessionCount and then call KillSession to make the deployed application kill all sessions in Appeon Server when there are up to 100 active sessions in the server.
proxyobject.of_execinterface ( "getSessionCount", ref any paralist[] )
Table 15.
|
Argument |
Description |
|---|---|
|
proxyobject |
The instance of the proxy object generated for AppeonDotNetComponent. |
|
paralist[] |
Arrays of Any type. Specifies the parameter arrays for the component function. paralist[1] - The name of the Appeon Server in which the active sessions are created. The value should be IP address or IP address with port number, for example, 192.0.0.123, or 192.0.0.123:8080, and separated with semicolons (;) if there are multiple servers (for example in an Appeon Server cluster). If paralist[1] is NULL or an empty string (""), getSessionCount returns the number of the active sessions in an Appeon Server cluster. paralist[2] - The name of the application that is deployed to the Appeon Server for which you want to know how many sessions are opened. If paralist[2] is NULL or empty string (""), getSessionCount returns the total number of active sessions in the specified Appeon Server. |
Return value of of_execinterface
Returns 0 if of_execinterface function succeeds and one of the following negative values if an error occurs.
-1: function fails to execute
-2: the specified Appeon Server is not found
-3: the specified application is not found
Return value of getSessionCount
Returns the number of active sessions if getSessionCount function succeeds and returns an empty string if an error occurs.
The return value is stored in the ReturnValue property of the proxy object.
Code example
Any la_l[]
Long lRet
...
la_l[1] = ls_servername
la_l[2] = ls_appname
lRet = loadDBList.of_ExecInterface ("getSessionCount", la_l) //result is returned to loadDBList.ReturnValueio_ejb.regstring ( String serverName )
io_ejb.regstring ( String appName )
io_ejb.Invokeretint ( long objid, "getSessionCount", true, ref integer retval )
Table 16.
|
Argument |
Description |
|---|---|
|
io_ejb |
A reference of Appeon EJBobject. |
|
serverName |
The name of the Appeon Server in which the active sessions are created. The value should be IP address or IP address with port number, for example, 192.0.0.123, or 192.0.0.123:8080, and separated with semicolons (;) if there are multiple servers (for example in an Appeon Server cluster). If serverName is NULL or an empty string (""), getSessionCount returns the number of the active sessions in an Appeon Server cluster. |
|
appName |
The name of the application that is deployed to the Appeon Server for which you want to know how many sessions are opened. If appName is NULL or empty string (""), getSessionCount returns the total number of active sessions in the specified Appeon Server. |
|
objid |
The handle to the component method. |
|
retval |
The return value of getSessionCount function: the number of active sessions opened for the specified application in the specified Appeon Server. This parameter must be declared, but need not to be assigned with values, as it is used to hold the return value. |
Return value of Invokeretint
Returns 0 if Invokeretint function succeeds and one of the following negative values if an error occurs.
-1: function fails to execute
-2: the specified Appeon Server is not found
-3: the specified application is not found
Return value of getSessionCount
Returns the number of active sessions opened for the specified application in the specified Appeon Server if getSessionCount function succeeds or returns an empty string if an error occurs.
The return value is stored in the retval parameter of Invokeretint function.
Code example
Note invokeretint function is called because the return value is an integer.
string ls_msg int retval01 ... io_ejb.regstring (ls_servername) io_ejb.regstring (ls_appname) ls_msg = io_ejb.invokeretint (il_bean1, "getSessionCount", true, ref retval01) //result is returned to retval01
getSessionCount ( string serverName, string appName )
Table 17.
|
Argument |
Description |
|---|---|
|
serverName |
The name of the Appeon Server in which the active sessions are created. The value should be IP address or IP address with port number, for example, 192.0.0.123, or 192.0.0.123:8080, and separated with semicolons (;) if there are multiple servers (for example in an Appeon Server cluster). If serverName is NULL or an empty string (""), getSessionCount returns the number of the active sessions in an Appeon Server cluster (you will need to configure the cluster in AEM first). |
|
appName |
The name of the application that is deployed to the Appeon Server for which you want to know how many sessions are opened. If appName is NULL or empty string (""), getSessionCount returns the total number of active sessions in the specified Appeon Server. |
Return value
Long.
Returns the number of sessions in the specified Appeon Server if the function succeeds or returns -1 if an error occurs.
Code example
//-- connected with the web service …… Long ll_return String ls_server, ls_app ls_server = sle_1.text ls_app = sle_2.text ll_return = ieon_ws.getSessionCount (ls_server, ls_app)
