CDS object entry, or both. If you need ACL permissions, see your CDS
administrator.
The ACL permissions are as follows:
• To create an entry, you need insert permission to the parent directory.
• To read an entry, you need read permission to the CDS object entry.
• To write to an entry, you need write permission to the CDS object entry.
• To delete an entry, you need delete permission either to the CDS object entry or to
the parent directory.
• To test an entry, you need either test permission or read permission to the CDS object
entry.
Note that write permission does not imply read permission.
13.2.7 Listening for Calls
When a server is ready to accept remote procedure calls, it initiates listening, specifying
the maximum number of calls it can execute concurrently; it does this by calling the
rpc_server_listen() routine. If a server allows concurrent calls, its remote procedures
are responsible for concurrency control. If executing a set of remote procedures
concurrently requires concurrency control and a server lacks this control, the server must
allow only one call at a time.
Under normal circumstances, the rpc_server_listen() routine does not return but the
RPC runtime continues listening for new remote procedure calls to the server’s
registered interfaces until one of the following events occurs:
• Any of the server’s procedures makes a local management call to stop a server from
listening for future remote procedure calls.
• For applications whose servers enable clients to stop servers from listening, a client
makes a remote management call to stop a server from listening for future remote
procedure calls.
On receipt of a stop listening request, the RPC runtime stops accepting new remote
procedure calls for all registered interfaces. However, currently executing calls are
allowed to complete. After all executing calls complete, the listen operation stops
listening and returns control to the server. Servers should unregister endpoints after they
stop listening.
13.3 How Clients Find Servers
A client runtime can obtain server binding information from a namespace. Alternatively,
a client can obtain server binding information in string format from an application-
specific source such as a file. Runtime routines enable client applications to obtain
