Error description
Before CICS sends an outbound HTTP request it first sends an HTTP Options request to check what HTTP level is supported by the target server. This extra request is often no handled properly by the target server and its presence can be a detriment to performance. This APAR is being taken to only use OPTIONS when necessary.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Performance of an outbound Web * * Services request is poor, especially * * if the server does not support * * handling of the HTTP OPTIONS method. * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS/TS 3.1 Outbound Web Services Support uses CICS Web Support(WEB OPEN) internally to connect to a server. WEB OPEN sends a HTTP flow to the server to capture and save the HTTP version of the server, required for any API processing that may follow. The Web Services path is subjected to this extra flow even though it has no need to know the version. The cost in pathlength of this flow is exaggerated if the server does not have handling for the method used in this flow(ie.OPTIONS), as the result may be that the connection is closed, meaning that CICS has to recover by issuing a reopen.
Problem conclusion
Temporary fix
FIX AVAILABLE BY PTF ONLY
Comments
Outbound CICS Web Services will no longer send an OPTIONS request.
