4 Typische Situationen im Application Development Fehler durch Abweichungen zwischen Development- und Produktionsumgebungen Time to market Verlangen nach kürzeren Innovationszyklen Manuelle Prozesse, keine Wiederholbarkeit, Kopfmonopole Deployment großer Releases dauert Tage, hunderte Mitarbeiter sind eingebunden Dev Wer kennt sich damit aus? Ich mache erstmal Pause. Tägliche Builds David Prod Test David hat Urlaub Release

5 Wo kommen die Probleme her? Requirements Design Code Build Change & Configuration Management Komponententest Deploy Test Staging und Testing sind Ressourcen- und Zeitaufwändig Integrationstest Deploy Test Ca. 1/3 bis 2/3 der Zeit wird für Setup und Konfiguration verwendet! Oft keine durchgängigen Verfahren verwendet Systemtest Deploy Test Kein sauberes Konfigurationsmanagement der einzelnen Stages Kopfmonopole Abnahmetest Deploy Test Production

6 DevOps Prinzipien und Grundwerte Bereichsübergreifende Zusammenarbeit Häufiges und regelmäßiges Deployment als wiederholbarer und zuverlässiger Prozess Menschen Prozesse Informationen Entwicklung- und Test auf produktionsnahen Systemen Kontinuierliche Überwachung und Validierung von operationalen Qualitätsfaktoren

7 Continuous Delivery for the Mainframe New capabilities to speed delivery of interdependent, multi-platform applications IBM UrbanCode Deploy for z/os Deploy Test Environment RD&T Download build output from artifact repository on z/os Deploy to z/os or RD&T to test application changes Promote Application under test Einheitliche Lösung für Continous Delivery für heterogene Umgebungen Delivery/Deployment als wiederholbarer und zuverlässiger Prozess Risiken und Kostenminimierung für teure Nacharbeiten

8 High Level Architecture Build System z/os LPAR, Build system Fetch artifacts via copy or FTP Agent z/os LPAR Post build script z/os CodeStation In HFS Store version artifacts Review PDS in version and request deploy process deploy Download artifacts Pre-processing steps TSO, REXX, SHELL PDS Create new version z/os DeployToolkit Store meta data Server Deploy data sets Update Inventory status Post-processing steps TSO, REXX, SHELL

9 Vorgehen eines Multiplattform Deployments UrbanCode Deploy z/os LPAR Agent Download artifacts deploy Application Pre-processing steps TSO, REXX, SHELL PDS Mainframe Komponente Loadmodules, JCL, SQL Deploy data sets Post-processing steps TSO, REXX, SHELL Distributed Komponente JAVA EAR Deployment

11 Code Rules wie heißt es nun eigentlich? Code Rules Cobol Regeln Code Review Codierrichtlinien Software Analyzer

12 9.1

13 Funktionalitäten Unterstützte Sprachen PLI Cobol JAVA Ausgelieferte Regeln Spezielle Funktionalitäten Delta-Analysen (Baseline Analysis) Aufrufschnittstellen RDz Eclipse Client (Editor) Workstation Batch z/os Batch Interface

14 Baseline Analysis Vergleich zweier Software Analyzer Läufe Analyse des Deltas welche neuen Verstöße sind entstanden

15 Aufrufschnittstellen BATCH Workstation Verfügbar auf Windows und Linux Source und Includes müssen vorliegen (bzw. über PropertyGroup bekannt gemacht werden)

16 Aufrufschnittstelle BATCH z/os (RDZ 9.1) Separate SMPE Prozess für die Bereitstellung FMID HAKG910 JCL Procedure AKGCR, der eine REXX Schnittstelle, die dann JAVA, aufruft Vorgehen Export Rules / Custom Rules und Eigenschaftsgruppe nach USS Nutzung der JCL Procedure AKGCR
