Summary of z/VM® Extension Routines
These
routines are individually described in detail in an appendix in the Common Programming Interface Communications Reference. They are
shown here in alphabetic order by coded routine name.
Coded
Routine Name |
Routine Pseudonym | Routine Description |
---|---|---|
XCECL | Extract_Conversation_LUWID | Extracts the SNA LU 6.2 architected Logical Unit of Work ID for a protected conversation. |
XCECSU | Extract_Conversation_Security_User_ID | Extracts the access security user ID associated with a conversation. |
XCECWU | Extract_Conversation_Workunit_ID | Extracts the CMS work unit ID for a conversation. |
XCELFQ |
Extract_Local_Fully_Qualified_
LU_Name |
Extracts the local fully-qualified LU name for a conversation. |
XCERFQ |
Extract_Remote_Fully_Qualified_
LU_Name |
Extracts the remote fully-qualified LU name for a conversation. |
XCETPN | Extract_TP_Name | Extracts the resolved TP name for a conversation. |
XCIDRM | Identify_Resource_Manager | Declares to CMS a name (resource ID) by which the resource manager application will be known. For a local resource manager, this routine makes the name known to the system; for a global resource manager, this routine also makes the name known to the TSAF and CS collection. |
XCSCUI | Set_Client_Security_User_ID | Lets an intermediate server specify an alternate user ID (the user ID of a specific client application). |
XCSCSP | Set_Conversation_Security_Password | Sets the access security password value for the conversation. The security type must be PGM. The target LU uses this value and the user ID to verify the identity of the security requester. |
XCSCST | Set_Conversation_Security_Type | Sets the security type (NONE, SAME, or PGM) for the conversation. The security type determines what security information is sent to the target. This lets the target verify the identity of the requester. |
XCSCSU | Set_Conversation_Security_User_ID | Sets the security user ID value for the conversation. The security type must be PGM. The target LU uses this value and the security password to verify the identity of the requester. |
XCSUE | Signal_User_Event | Queues an event to be reported by a subsequent Wait_on_Event call in the same virtual machine. |
XCTRRM | Terminate_Resource_Manager | Ends ownership of a resource by a resource manager program. |
XCWOE | Wait_on_Event | Waits on communications from one or more partners, and other events. Events reported are user events, allocation requests, information input, notification that a resource has been revoked, console input, and asynchronous Shared File System (SFS) requests. |
