Important Entries for the Execution Roadmap Step
This chapter deals with the roadmap step Execution, in which the system is in downtime and the Software Update Manager converts application tables and data to match the target release layout.
Actions After Shutdown (Phase STOPSAP_<X>)
If you want to use transaction RZ10 to adjust the instance profile during or after the update, start by reimporting the current version of the profile into your SAP system. If you do not do this, the changes made by the update are reset, which can cause the update to stop running.
Modification Adjustment and Activation (Phase ACT_UPG)
Profile of User <SID>Adm (Phase ENVFILES_COPY)
In this phase, the environment files are copied from the envfiles subdirectory to the home directory of the <SID>adm user on the target system. Here, they are saved again with lowercase file names as follows:
| DBENV.CSH | → .dbenv.csh |
| DBENV.SH | → .dbenv.sh |
| SAPENV.CSH | → .sapenv.csh |
| SAPENV.SH | → .sapenv.sh |
If additional application servers with an own home directory of user <SID>adm exist, copy the environment files to these servers.
Any changes you made to the files after the ENVFILES_PREP phase and before the ENVFILES_COPY phase are then applied to the target system. For more information, see Customizing of Environment Profiles.
Manual Actions for the ASCS Instance (Phase REQ_ASCS_SWITCH)
-
you are running the ASCS instance on a separate host (for example, in a high availability environment)
-
the operating system of the host is different from that on the primary application server instance
Database Archiving and Backup (Phase STARTSAP_PUPG)
You are asked to make a full backup of your database. If you have deactivated archiving, you are asked to change the archiving mode of your database.
For more information about database archiving and backup strategies, see Database-Specific Aspects.
