Problem Note 35556: Error message "sam.S235.ex" might occur when repeatedly opening and closing the SAS® Stored Process Server _webout connection
 |  |  |  |
When running stored processes using the SAS Stored Process Web Application, output might not be returned to the client's Web browser if the stored process repeatedly opens and closes the _WEBOUT connection. The stored process server might become unresponsive and you might receive the following error message in your Web Server's log file:
[ERROR] < User Name Here > com.sas.services.storedprocess.Execution - com.sas.services.storedprocess.SASServerException: Wraps an exception thrown while accessing the SAS Server. at com.sas.services.storedprocess.Execution.doExecuteStoredProcessServerStoredProcess(Execution.java:1533) at com.sas.services.storedprocess.Execution.access$300 Caused by: org.omg.CORBA.COMM_FAILURE: sam.S235.ex.msg: An exception was thrown while reading a packet header from the socket. vmcid: 0x0 minor code: 0 completed: No at com.sas.net.brg.sam.SocketAccessMethod.getReply(Unknown Source) at com.sas.net.brg.sam.SocketAccessMethod.sendRequest(Unknown Source) at com.sas.net.brg.BridgeProtocolEngine.requestByName(Unknown Source) at com.sas.net.brg.RequestImpl.invoke(Unknown Source)
The following stored process code will illustrate the problem.
/* This code incorrectly creates HTML "top matter" repeatedly. */
%macro repeat;
%do i = 1 %to 100;
%stpbegin; /* Route output to _WEBOUT */
proc print data=test;
run;
%stpend;
%end;
%mend repeat;
%repeat;
In the above example, the %STPBEGIN macro routes output to the _WEBOUT fileref (which is directed to the client user's Web browser). This code is incorrect. ODS generates multiple, redundant tags for <!DOCTYPE>, <HTML>, <HEAD>, <BODY> and their associated content and closing tags.
You can avoid this problem by using the ODS options no_top_matter and no_bottom_matter. Either of the following approaches should avoid the problem.
- Add the following four statements at the top of the above code:
%let _ODSDEST=html; ods &_ODSDEST body=_webout (no_bottom_matter); ods &_ODSDEST close; %let _ODSOPTIONS=%str(body=_webout(no_top_matter no_bottom_matter));
- This alternative approach does not use the %STPBEGIN and
%STPEND macros.
ods html body=_webout(no_bottom_matter); ods html close; %macro repeat; %do i = 1 %to 100; ods html body=_webout(no_top_matter no_bottom_matter); proc print data=test; run; ods html close; %end; %mend repeat; %repeat;
