Issus Faced

Issues faced:

 During Java SPS upgrade:

• We do not have the java system added in maintenance planner/support portal. As a solution we have downloaded and ran SUM tool to generate system.info file and uploaded in marketplace and later generated the stack.xml file

• After launching the SUM, we got an error message: System Detect : solution added the hostname and IP address in etc/hosts file.

• During confirm target phase got en error saying that selected media during the creation of stack.xml file not available in the media directory

. Major error During execution phase deploy java components phase not moved  for around 2 hours, after checking we found that connection to the server not working.

The issue is the server not starting in safe mode. as suggested in the SAP note, we have removed the server from safe mode using CONFIGTOOL and started the server. Later executed SUM and started the upgrade successfully completed.

Issue 2: SAP system connection using web-dispatcher was not working after the parameters upgrade.

As part of SAP application maintenance, we have upgraded several security related parameters in ACL file in /usr/sap/global/acl_http_file.

Solution: we have added the Ip address and hostnames of webdispather servers in the acl_http_file then it got resolved.
