Unit 15: Structured Troubleshooting ADM100
• Call transaction ST22. Choose Goto → Reorganize. You can now
specify that all short dumps older than n days old (default 7) are to be
deleted. If a very large number of records are deleted at once during
the reorganization, ORACLE error ora1562, failed to extend rollback
segment ..., can occur. In this case, see SAP Note 6328.
• Dropping and recreating table SNAP with the database utility
(transaction SE14): you can use this transaction to drop and recreate
the table SNAP. This means that all short dumps are deleted.
• The reorganization program RSSNAPDL deletes old short dumps in
pieces (to avoid database problems) from table SNAP. It deletes short
dumps that are not flagged for retention and are older than seven
days old. Schedule this program at a time of low workload, as large
changes in the database are to be expected. The program RSNAPJOB
performs a standard scheduling: it starts the program RSSNAPDL
every day at 1:00 a.m..
• Table SNAP is also automatically reorganized.Ateveryshortdump
that occurs in dialog (the dump is displayed immediately after it is
created), a maximum of 20 short dumps that are older than 7 days
old are deleted from SNAP. This reorganization should be sufficient
in normal production operation.
At this point, you can demonstrate transaction ST22. Execute a function
module that can be used for remote connections in the Function Builder
(transaction SE37), such as RFC_READ_TABLE for table T000, or
RFC_SYSTEM_INFO as described in the exercise. Use the RFC connection
TRACES_ST22. A short dump is generated. You can analyze this in
transaction ST22. Show the short dump and the options for reorganization
and retention of messages.
SAP System Trace
You can use the system trace to record internal system activities. The
system trace is primarily used if an authorization trace is to be created. We
recommend that you use the system log or the developer trace for system
monitoring and problem analysis. You can call the SAP System Trace using
transaction ST01 or by choosing the menu path Tools → Administration →
Monitor → Traces → System Trace. YoucanalsousetransactionST01to
display the inactive trace file.
You can use the SAP system trace to monitor the following components:
