Solutions include increasing buffer size in the SAP profile, ensuring sufficient memory to avoid swapping, and customizing values based on the system release, data volume, and applications. Profile changes require a system restart and should be verified using transaction ST02 . This document explains how to analyze ST02 (Tune Summary) in SAP systems, how to correctly interpret buffer and swap values, and how to perform a technically sound troubleshooting instead of directly increasing buffer sizes. This document is written based on personal hands-on experience gained from. The system log has entries indicating buffer overflows for types TABL, TABLP, and CUA, specifying issues with fully or generically buffered tables, single record buffers, and the CUA buffer. The overflow occurs due to directory overflow or the lack of free data frames, identifiable using. ST02 – program buffer, screen, calendar, roll area, paging area, extended, heap memory (dialog – roll first, extended, roll area, heap then work process goes to PRIV mode) (non-dialog – roll area, heap, extended, page). Current Parameters will give more details. The single wire interface module (SWIM) and the JTAG/serial wire debugging (SWD) interfaces facilitate communication with any STM8 or STM32 microcontroller operating on an application board. In addition to. My system always running well but today I found there are lots of swaps in ST02, but the hitratio is almost beyond 95%, may I know whether this is normal or abnormal? and how can I reduce them? or is it possible that there is no any red area in ST02? For details please have a look at the picture. In ST02 of one of the system all the apps I see many SWAPS column with value and in red color, what it mean program, swaps with 11,349 generic key with 68 single record with 1,002 Thanks Vijay Know the answer?
