The Compute API enables users to submit and execute SAS code using REST calls. Users can manage Compute contexts, create sessions, submit jobs, and access information about the session.

The Compute API defines the replacement for the application servers that were used for SAS 9. The Compute API enables clients to perform the following tasks: <UL> <LI>Submit and execute SAS code. <LI>Obtain the SAS log or listing information from executed SAS code. <LI>View output that is generated by a SAS code submission. <LI>Access SAS data sets that are created by a SAS code submission. <LI>Access SAS filerefs that are created by a SAS code submission. <LI>Access SAS variables that are defined and used in a SAS code submission. <LI>Retrieve information about engines that are available in a session. </UL>

This API defines the replacements for SAS Application Servers that have been used throughout SAS Version 9.

  There are endpoints that are described by this API that enable you to use create,
read, update, and delete operations to define a Compute context. A Compute context is analogous to the SAS Application Server from SAS V9.
There are also endpoints that enable you to request a SAS Compute Server session. This session runs on a SAS Compute Server and serves as the access point to SAS client processing in this environment. This session functions as the replacement for SAS Workspace Server and SAS Stored Process Server functionality from SAS V9.

A context is created for a user. Context names should be specific to each application or product that they pertain to. For example, SAS Studio might have a context that is named 'SASStudio'. A context contains all the information that is needed to instantiate sessions from that context.

To execute SAS code, request a session by POST to a URL, such as /compute/sessions/?contextName=SASStudio. Either a SAS Compute Server instance is found that matches the request or a new instance is started. A server is assigned a GUId that is used to identify it. A new session is created for a user in the SAS Compute Server, links to the session are created, and other server links are provided. Sessions are assigned a counter identifier, such as 001 or 002. You can then issue a POST request to the session URI with that identifier. For example, use the /compute/sessions/001/job path to execute SAS code in session 001. Include the code that you want to execute in the body of the POST request.

Links to a job are provided in the response to the POST request to execute code. These links enable you to execute and access multiple submissions from the same session. To access the state of a submission, the results, the log, or listings that are generated by code execution, use the links that are provided in the response to POST for a job. For example, sessions/001/jobs/1/log accesses the log that is generated by the first submission to session 001.

>

Returns the current state of the specified job.

Specifies the ETag that is associated with a value of the job state.

If-None-Match

sessionId

Specifies the ID of the job to return information for.

jobId

Specifies the request time-out, in seconds. This parameter is ignored unless it is specified in combination with the `If-None-Match` header. If the state of the resource remains unchanged until the specified number of seconds has elapsed, then a status of 304 is returned. The request determines whether the current state matches the state when the ETag was specified via the `If-None-Match` header. If the state differs within the specified time period, then the new state is returned.

wait

Specifies a tag that identifies the revision of this object.

ETag

The session state has not changed since the request was issued using the ETag that is specified in the `If-None-Match` header.

Error

application/vnd.sas.error

The request was invalid. The session is in a state that cannot process this request.

No resource exists at the requested path.
