Method Details

transferSessionId

public static void transferSessionId(Long prevSessionId,
 Long newSessId)

forceReleaseSessionId

public static void forceReleaseSessionId(Long sid)

This method is to allow manual forcing to release of the memory associated with a session. In some cases, depending on how programs are started and released, some programs may never have been removed, causing a memory leak / ever increasing memory requirement by the runtime application.

Parameters:

sid -

create

public static BaseService create(ISMObject classNameVar,
 IBaseService parent)

create an instance of the target class. This is used during translation of cobol's CALL Statements.
NOTE: Unless the ServicesFactory.cancel method is used to cancel the called program (by the caller), the system will cache the called-program and the next call to ServicesFactory.create (from same session) will return the same instance of the called-program, with all the data preserved.

Parameters:

parent - : Calling object Used to retrieve Session information, screen information, etc.

_className - : full packageName and class name. E.g. com.softwaremining.examples.Class1, or
just the name e.g. CLASS1 - in this case the system will use the "parent" package, and capitalize "CLASS1" to produce com.softwaremining.examples.Class1 .
Alternatively the package name may supplied by Config.EXTERNAL_SERVICES_PACKAGE_NAME (from entry in softwaremining.properties).

Returns:

create

public static BaseService create(String _className,
 IBaseService parent)

create an instance of the target class. This is used during translation of cobol's CALL Statements.
NOTE: Unless the ServicesFactory.cancel method is used to cancel the called program (by the caller), the system will cache the called-program and the next call to ServicesFactory.create (from same session) will return the same instance of the called-program, with all the data preserved.

Parameters:

_className - : full packageName and class name. E.g. com.softwaremining.examples.Class1, or
just the name e.g. CLASS1 - in this case the system will use the "parent" package, and capitalize "CLASS1" to produce com.softwaremining.examples.Class1 .
Alternatively the package name may supplied by Config.EXTERNAL_SERVICES_PACKAGE_NAME (from entry in softwaremining.properties).

parent - : Calling object Used to retrieve Session information, screen information, etc.

Returns:

cancelService

public static void cancelService(String className,
 IBaseService parent)

remove service from cached program. Next call to ServicesFactory.create will create a fresh instance of the program

Parameters:

className -

parent -

cancelCicsCalledPrograms

public static void cancelCicsCalledPrograms(IBaseService progInstance)

removeSession

public static void removeSession(BaseService parent)

For internal use only.
Used by Conversational Servlet engine once application has finished

getNameToServiceMappingProperties

public static Properties getNameToServiceMappingProperties(boolean throwExceptionIfNotFound)

Used internally by CICS applications - Attempt to locate and load "services.properties" This property file will contain a mapping between name of a program, and an equivalent java-class.
for example:
prog1=Program1
prog2=Program2

Returns:

printStats

public static String printStats()
