1,007 views

Published on

Sie betreiben SAP NetWeaver IdM und wollen Ihre Performance verbessern? Sie möchten Ihre IdM Lösung zum Roll-Out führen und benötigen dafür eine Performanceoptimierung? Dann sollten Sie auf keinen Fall unser Webinar verpassen, denn als Datenbanklösung ist SAP NW IdM sowohl von der Konfiguration Ihrer Datenbank als auch von der Qualität der Implementierung abhängig. Selbst nach einer sauber durchgeführten Implementierung kann es zu Performanceproblemen kommen. Diese gefährden den gesamten Projekterfolg. Damit Ihr Projekt zum Erfolg wird, stellen wir Ihnen typische Probleme und ihre Ursachen vor, bieten einen Überblick über die für die Performance Ihres IdM Systems relevanten Aspekte und weisen mögliche Lösungsansätze und Optimierungspotenziale auf.

  7. 7. SAP NW IdM Performance SAP NW IdM kann mit wachsender Größe und Komplexität an Verarbeitungsgeschwindigkeit nachlassen. Als Datenbankanwendung ist das SAP NW IdM sehr abhängig von der Konfiguration der Datenbank und der Implementierung. Verschiedene Gebiete und Aspekte der Lösung, die Einfluss auf die Performance haben.Seite 7 www.ibsolution.de © IBSolution GmbH 22.10.2012
  8. 8. SAP NW IdM PerformanceTypische Probleme IdM reagiert nur noch sehr schlecht oder gar nicht auf BenutzereingabenMögliche Ursachen:Dynamischen Gruppen sind oft Ursache für Performance Problemen. Mögliche Lösungsansätze:  Optimieren der Filterkriterien (Anpassung SQL)  Auslagern von Daten welche zur Berechnung benötigt werdenLang laufende IdM Jobs welche das System blockieren. Mögliche Lösungsansätze:  Umplanung und prüfen der Abhängigkeiten  Optimierung der ‚Source Statements‘ (Anpassung SQL)  Aufteilen der Jobs in einzelne, granularere, JobsSeite 8 www.ibsolution.de © IBSolution GmbH 22.10.2012
  9. 9. IdM ArchitekturBei der Analyse der Performance Probleme ist das Verständnis für die Architektur wichtig SAP NW IdM ist eine Datenbankanwendung Java Prozesse Arbeiten Jobs ab SAP NW GUI läuft auf dem SAP NW Java ASSeite 9 www.ibsolution.de © IBSolution GmbH 22.10.2012

  12. 12. Implementierung / SkripteEinfluss auf die Performance haben SQL Abfragen innerhalb von Skripten uSelect vs. direktem Datenbankzugriff mxmc_rt connect bei großen Datenmengen Zu viele SQL Abfragen innerhalb eines skripts (Schleifen) In Memory Verarbeitung: On Init / On Entry / On TerminateSeite 12 www.ibsolution.de © IBSolution GmbH 22.10.2012
