Summary :
This SAP Note addresses issues encountered when using the sapcontrol utility, particularly relating to authentication errors such as HTTP/1.1 401 Unauthorized, invalid credentials, and connection refusals. Key concerns include improper handling or absence of /tmp/.sapstream5$$13 or \\.\pipe\saptcontrol_$$ on Unix and Windows respectively, incorrect user execution permissions, and possibly misconfigured or failing services such as sapstartsrv. Solutions include file management, service restarts, permission checks, relevant SAP Note references, and PAM configuration reviews. Ensure that all operations are performed under the correct user context, namely adm, and verify service operational status to resolve issues effectively.
