The named pipes capability is one of the most powerful tools available in SAS underWindows for communicating with other applications. In this blog, we discuss Communicationusing named pipes among SAS sessions to achieve the distributed structure.

(1)One Server Connected to Several Clients

(2) Inthe first SAS session(Server), submit the following statements

1. filename channel namepipe '\\.\pipe\test'
   
2.          server eofconnect retry=20;
   
3. data parent;
   
4.    infile channel;   
   
5.    input machine $ message $ time $;
   
6. run;

复制代码

(3) Inthe second and third SAS session, you can use SAS statements to exchange data between the two SAS sessions. For example, you can submit the following program from the client session

1. filename channel namepipe '\\.\pipe\test'
   
2.          client retry=-1;
   
3. data child1;
   
4.    input machine $ message $;
   
5.    time=datetime();
   
6.    format time datetime.;
   
7.    file channel;
   
8.    put machine $ message $ time $;
   
9.    datalines;
   
10. 进程1 hello
    
11. 进程1 good
    
12. 进程1 bad
    
13. ;
    
14. run;

复制代码

1. filename channel namepipe '\\.\pipe\test'
   
2.          client retry=-1;
   
3. data child2;
   
4.    input machine $ message $;
   
5.    time=datetime();
   
6.    format time datetime.;
   
7.    file channel;
   
8.    put machine $ message $ time $;
   
9.    datalines;
   
10. 进程2 I
    
11. 进程2 Miss
    
12. 进程2 U
    
13. ;
    
14. run;
