Summary :
This SAP Note addresses issues with the guide and upgrade procedures on i5/OS platforms, focusing on five critical aspects: general information, guide errors, pre-upgrade activities, individual phase problems, and post-upgrade activities. Notably, it corrects permission errors for shell scripts post-SDM update, directs proper JVM usage before upgrades, and outlines necessary environmental settings and patches such as SAPJAVA 4.1 for Java Virtual Machine compatibility and SAPSTART for system initialization. Key phase issues include SCS starts, error handling in START_J2EE_INITIAL, and appropriate deployment tactics for XI Adapter Framework, ensuring a smooth upgrade experience.
