Using the WebLogic Scripting Tool (WLST), you can dynamically list the connections for a domain with the listConnectionsConfigured() attribute. When you run cmo.listConnectionsConfigured(), a reference to an array of DSessConnInfo structures is returned. It is convenient to save this in a local WLST variable, such as

wls:/mydomain/serverRuntime/WTCRuntime/WTCService> r=cmo.listConnectionsConfigured()

Each DSessConnInfo instance has a local access point ID, remote access point ID, and status (boolean, true = connected, false = not connected). For example,

wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].getLocalAccessPointId()
WLSDOM
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].getRemoteAccessPointId()
TUXDOM
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].isConnected()
0

Using the WebLogic Scripting Tool (WLST), you can dynamically start individual connections for an access point with the startConnection() attribute.

To start a connection between a local and a remote access point, specify the access point IDs in the arguments. For example,

cmo.startConnection('WLSDOM','TUXDOM')

To start a connection between a local and all associated remote access points, specify the local access point ID in the argument. For example,

cmo.startConnection('WLSDOM')

Using the WebLogic Scripting Tool (WLST), you can dynamically stop individual connections for an access point with the stopConnection() attribute.

To stop a connection between a local and a remote access point, specify the access point IDs in the arguments. For example,

cmo.stopConnection('WLSDOM','TUXDOM')

To stop all connections involving a given local access point, specify the local access point ID in the argument. For example,

cmo.stopConnection('WLSDOM')

The following code list is an example of dynamically listing, starting and stopping connections using WLST.

java weblogic.WLST
wls:/offline> connect('weblogic','weblogic')
wls:/mydomain/serverConifg> cd('WTCServers')
wls:/mydomain/serverConfig/WTCServers> cd('myWTC')
wls:/mydomain/serverConfig/WTCServers/myWTC> cd('LocalTuxDoms')
wls:/mydomain/serverConfig/WTCServers/myWTC/LocalTuxDoms> ls()
dr--   TDOM2
wls:/mydomain/serverConfig/WTCServers/myWTC/LocalTuxDoms> cd('../../..')
wls:/mydomain/serverConfig> serverRuntime()
wls:/mydomain/serverRuntime> cd('WTCRuntime')
wls:/mydomain/serverRuntime/WTCRuntime> cd('WTCService')
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> r=cmo.listConnectionsConfigured() 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].getLocalAccessPointId()
TDOM2
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].getRemoteAccessPointId()
TDOM1
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].isConnected()
0
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> cmo.startConnection('TDOM2','TDOM1') 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> r=cmo.listConnectionsConfigured() 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].isConnected() 
1
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> cmo.stopConnection('TDOM2','TDOM1') 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> r=cmo.listConnectionsConfigured() 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> print r[0].isConnected() 
0 
wls:/mydomain/serverRuntime/WTCRuntime/WTCService> disconnect() 
wls:/offline> exit() 

Using the WebLogic Scripting Tool (WLST), you can dynamically modify a configuration attribute.

The following code listing is an example that modifies the setInteroperate() attribute.

java weblogic.WLST
wls:/offline> connect('weblogic','weblogic')
wls:/mydomain/serverConifg> edit()
wls:/mydomain/edit> startEdit()
wls:/mydomain/edit> cd("WTCServers/myWTC")
wls:/mydomain/edit/WTCServers/myWTC> cd("LocalTuxDoms")
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms> cd("TDOM2")
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> cmo.setInteroperate("Yes")
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> validate()
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> showChanges()

Changes that are in memory and saved to disc but not yet activated are:

MBean Changed           : mydomain:Name=TDOM2,Type=WTCLocalTuxDom,WTCServer=myWTC
Operation Invoked       : modify
Attribute Modified      : Interoperate
Attributes Old Value    : No
Attributes New Value    : Yes
Server Restart Required : false

wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> save()
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> activate(block="true")
wls:/mydomain/edit/WTCServers/myWTC/LocalTuxDoms/TDOM2> disconnect()
wls:/offline> exit()

To determine the status of a service, specify the SvcName, LDOM, or RDomList in the arguments. For example,

int WTCService.getServiceStatus(String SvcName)

In this case, the code returns a status of all the imported and exported services with the name SvcName for the targeted WTC server. If there is more than one imported service or exported service with the same resource name 'SvcName', then if at least one service is available, the status will return AVAILABLE. If there is more than one imported service or exported service with the same resource name 'svcName' and some services are suspended and some are unavailable, the status returns a SUSPENDED value. If all services are unavailable, the status returns an UNAVAILABLE value. TPException.TPENOENT is thrown when no match is found.

The legal values of the returned status are as shown in Table 4-1.:

You can suspend any imported or exported service advertised by a WTC server. Any service suspended administratively will become available only when either WTC server is redeployed, WLS server is rebooted, or the service is resumed administratively.

To suspend an available service, specify the SvcName, LDOM, or RDomList in the arguments. For example,

Void WTCRuntimeMBean.suspendService(String SvcName, boolean isImported)

This case suspends all the Import or Export services with the specified name. If isImported is true, then only imported services are suspended; if it is false, then only exported services are suspended. TPException.TPENOENT is thrown if nothing is found.

You can resume any imported or exported service advertised by a WTC server that has a status of suspended. Any service suspended administratively will become available only when either WTC server is redeployed, WLS server is rebooted, or the service is resumed administratively.

To resume a suspended service, specify the SvcName, LDOM, or RDomList in the arguments. For example,

void WTCRuntimeMBean.resumeService(String SvcName)

This example resumes all the Import and Export services with SvcName configured for the targeted WTC server. TPException.TPENOENT is thrown if no match is found.
