RECEIVE_ALLOCATE_EX_END

  • Artigo

The RECEIVE_ALLOCATE_EX_END verb allows an application to deregister as the attach manager for a given Local APPC LU (lu_alias). This verb must be called for each lu_alias previously passed to the RECEIVE_ALLOCATE_EX request.

Syntax

  
typedef struct receive_allocate_ex_end {  
       unsigned short opcode;  
       unsigned char reserv2[2];  
       unsigned short primary_rc;  
       unsigned long secondary_rc;  
       unsigned char tp_name[64];  
       unsigned char lu_alias[8];  
       unsigned char reserved3[20];  
 };

Members

Opcode
A supplied parameter. Specifies the verb operation code, RECEIVE_ALLOCATE_EX_END.

reserv2
A reserved field.

primary_rc
If the lu_alias has not been previously registered by the application, the following error is returned:

AP_STATE_CHECK (0x0002)

secondary_rc
If the lu_alias has not been previously registered by the application, the following error is returned:

AP_ATTACH_MANAGER_INACTIVE (0x00000508)

tp_name
Must be all EBCDIC spaces (X'40')

lu_alias
Must be supplied and must match the lu_alias provided in a previous RECEIVE_ALLOCATE_EX request from the same process

reserved3
A reserved field.

Remarks

If the application is providing sync point support, the application needs to know when the LU-LU session limits have dropped to zero. This can be done by polling the GET_LU_STATUS API.

After calling RECEIVE_ALLOCATE_EX_END to deregister an attach manager, Host Integration Server does not tear down any existing LU6.2 sessions. To tear down an existing session, call the DEACTIVATE_SESSION function, supplying the appropriate lu_alias and plu_alias. If you are using Sync Level 2, deactivating the LU6.2 sessions notifies the Remote LU that the syncpoint manager has gone away and thus, a new ExchangeLogNames is required for the next connection.
