Unit 15: Structured Troubleshooting ADM100
In expert mode (menu path Edit → Expert Mode), you can extend the
selection criteria so that it is possible to search for entries for a particular
terminal. To do this, choose the Attributes button.
In UNIX systems, you can display the status of the send process in the SAP
system with transaction SM21 or by choosing Environment → Process Status.
You can define the path and file names for local and central log files with
the following system profile parameters:
• rslg/local/file: Filenameforthelocallog(Default:SLOG)
• rslg/central/file: Filenamefortheactivecentrallog(Default:SLOGJ);
does not apply for Microsoft Windows NT and AS/400 platforms
By default, the log files for the local system log are stored in the following
directory: /usr/sap///log. The central system log is
stored in /usr/sap//SYS/global
You can also schedule system logging as a background job. There are two
ABAP programs provided to do this:
• RSLG0000: To create the local system log
• RSLG0001: To create the central system log (not on Microsoft
Windows NT and AS/400 platforms)
At this point, you can demonstrate transaction SM21. Display details
for a message in the system log and jump from SM21 to the profiles: In
transaction SM21, choose Environment → Display SAPPARAM.
Dump Analysis
ABAP programs are checked statically when they are created and
dynamically when they are running. Error states, which are not statically
predictable and only occur at runtime are dynamically identified by the
ABAP runtime environment. States of this type lead to exceptions. If an
exception is not handled or cannot be handled, a runtime error occurs.
If a runtime error occurs, the ABAP runtime environment terminates
the execution of the program, generates a short dump and branches to
a special screen for analyzing the short dump. You can also find short
dumps in transaction ST22 or by choosing the menu path Tools → ABAP
Workbench → Test → Dump Analysis
