In this tutorial, we are going to perform the support package stack update for SAP Netweaver JAVA system. This execution will be using the Software Update Manager (SUM).
Prerequisite
- Generate the stack XML file
- Download the media files
- Perform the full backup
- Ensure the free space is sufficient
- Obtain the necessary users (j2ee_admin / sidadm] for SUM execution.
Steps
Step 1: Launch the SUM tool and copy the JAVA SUM URL to the web browser. You will need to login with the sidadm user.
STARTUP.BAT confighostagent SID
SUM Java: https://HOSTNAME:1129/lmsl/sumjava/SID/index.html (HTTPS)
SUM Java: http://HOSTNAME:1128/lmsl/sumjava/SID/index.html (HTTP)
Step 2: The initial screen of the SUM will detect the system type, SID and directory of the system.
Step 3: Choose Communication Protocol for SAPcontrol.
Step 4: Specify the OS user credentials.
Step 5: Select the target version definition for your system.
Note: The SAP-derived software archives are signed with digital signatures. If you want to check the signature authenticity of all archives in the download directory, select the checkbox below. If you select this option, you also have to download the Certificate Revocation List (CRL) from https://tcs.mysap.com/crl/crlbag.p7s and place it in the download directory, so that SUM also checks the archive certificates. For more information, see the SUM user guide.
Step 6: Confirm the target version. For more information (including the respective SP stack levels), see TargetSystemVersionReport.html.
Step 7: Input the JAVA administrator user credentials (administrator or j2ee admin).
Step 8: Install the maintenance license (if required).
Step 9: Double confirm the system parameters and click Next.
Step 10: Backup the following items,
- /usr/sap/SID/SYS/global/security
- Full database
- SUM directory
- /usr/sap/SID
Step 11: Execution runs.
Step 12: The downtime phase of the update has finished. Make sure that you have created all the backups before resuming the production operation.
Step 13: The summary of the update process as below. You can record the process runtime and system downtime for the next system update.
