ALL

static final int ALL

Used to indicate that INBOUND, OUTBOUND & WORK are to be suspended/resumed

Constant Field Values

suspend

void suspend(int type,
             Properties props)
             throws ResourceException

Request to suspend the activity specified. The Properties may be null or specified according to RA-specific needs

Parameters:

type - An int from 1 to 7 specifying the type of suspension being requested (i.e. Suspendable.INBOUND, .OUTBOUND, .WORK or the sum of one or more of these, or the value Suspendable.ALL )

props - Optional Properties (or null) to be used for ResourceAdapter specific purposes

Throws:

ResourceException - If the resource adapter can't complete the request

suspendInbound

void suspendInbound(MessageEndpointFactory endptFactory,
                    Properties props)
                    throws ResourceException

Request to suspend the inbound activity on the given MessageEndpointFactory

Parameters:

endptFactory - the factory for message endpoints that is being suspended

props - Optional Properties (or null) to be used for ResourceAdapter specific purposes

Throws:

ResourceException - If the resource adapter can't complete the request

resumeInbound

void resumeInbound(MessageEndpointFactory endptFactory,
                   Properties props)
                   throws ResourceException

Request to resume the inbound activity on the given MessageEndpointFactory

Parameters:

endptFactory - the factory for message endpoints that is being resumed

props - Optional Properties (or null) to be used for ResourceAdapter specific purposes

Throws:

ResourceException - If the resource adapter can't complete the request

resume

void resume(int type,
            Properties props)
            throws ResourceException

Request to resume the activity specified. The Properties may be null or specified according to RA-specific needs

Parameters:

type - An int from 1 to 7 specifying the type of resume being requested (i.e. Suspendable.INBOUND, .OUTBOUND, .WORK or the sum of one or more of these, or the value Suspendable.ALL )

props - Optional Properties (or null) to be used for ResourceAdapter specific purposes

Throws:

ResourceException - If the resource adapter can't complete the request

supportsSuspend

boolean supportsSuspend(int type)

Parameters:

type - An int from 1 to 7 specifying the type of suspend this inquiry is about (i.e. Suspendable.INBOUND, .OUTBOUND, .WORK or the sum of one or more of these, or the value Suspendable.ALL )

Returns:

true iff the specified type of suspend is supported

isSuspended

boolean isSuspended(int type)

Used to determine whether the specified type of activity is currently suspended.

Parameters:

type - An int from 1 to 7 specifying the type of activity requested (i.e. Suspendable.INBOUND, .OUTBOUND, .WORK or the sum of one or more of these, or the value Suspendable.ALL )

Returns:

true iff the specified type of activity is suspened by this resource adapter

isInboundSuspended

boolean isInboundSuspended(MessageEndpointFactory endptFactory)
                           throws ResourceException

Used to determine whether the inbound activity is currently suspended for the given MessageEndpointFactory

Parameters:

endptFactory - the endpoint factory

Returns:

true iff the inbound activity is suspened by this resource adapter

Throws:

ResourceException

supportsInit

boolean supportsInit()

Used to determine if this resource adapter supports the init() method used for resource adapter versioning (side-by-side deployment)

Returns:

true iff this resource adapter supports the init() method

supportsVersioning

boolean supportsVersioning()

Used to determine if this resource adapter supports the startVersioning() method used for resource adapter versioning (side-by-side deployment)

Returns:

true iff this resource adapter supports the startVersioning() method

startVersioning

void startVersioning(ResourceAdapter ra,
                     Properties props)
                     throws ResourceException

Used by WLS to indicate to the current version of this resource adapter that a new version of the resource adapter is being deployed. This method can be used by the old RA to communicate with the new RA and migrate services from the old to the new. After being called, the ResourceAdapter is responsible for notifying the Connector container via the ExtendedBootstrapContext.complete() method, that it is safe to be undeployed.

Parameters:

ra - The new ResourceAdapter JavaBean

props - Properties associated with the versioning when it can be undeployed

Throws:

ResourceException - If something goes wrong

init

void init(ResourceAdapter ra,
          Properties props)
          throws ResourceException

Used by WLS to inform a ResourceAdapter that it is a new version of an already deployed resource adapter. This method is called prior to start() so that the new resource adapter may coordinate its startup with the resource adapter it is replacing.

Parameters:

ra - The old version of the resource adapter that is currently running

props - Properties associated with the versioning operation

Throws:

ResourceException - If the init() fails.
