Diagnosing System Problems

Diagnosing system problems involves, among other duties, reviewing error messages, managing processes, performing dumps, starting and stopping servers.

• How SAP ASE Uses Error Messages
  SAP ASE displays an error message when it encounters a problem.
• SAP ASE error logging
  Error messages from SAP ASE are sent to the user’s screen and to the error log file.
• Backup Server Error Logging
  Like SAP ASE, Backup Server creates an error log if one does not already exist.
• Killing Processes
  A process is a unit of execution carried out by SAP ASE. The kill command removes ongoing processes.
• Using Shared Memory Dumps
  You can configure SAP ASE to dump shared memory to files when specific conditions occur (for example, segmentation faults).
• Housekeeper functionality
  The housekeeper task provides important background tasks.
• Shutting Down Servers
  A system administrator can shut down SAP ASE or Backup Server using the shutdown command.
• Learning about known problems
  The release bulletin is a valuable resource for learning about known problems or incompatibilities with SAP ASE and Backup Server. Reading the release bulletin in advance can save you the time and guesswork of troubleshooting known problems.
