  • Tipps & Tricks rund um CRSCTL

    - by Sebastian Solbach (DBA Community)
    Egal ob Single Instanz oder für Real Applikation Cluster Datenbanken die Grid Infrastruktur findet man bei immer mehr Systemen im Einsatz. Das liegt sowohl an der vereinfachten Überwachungstätigkeiten für die Oracle Datenbank, Listener und ASM Instanz, als auch an einigen weiterführenden Features, wie der einfachen Service Verwaltung für Single Instanz, DataGuard und/oder RAC. Dabei kommen insbesondere den Cluster Ready Services (CRS), einem Bestandteil der Clusterware Komponente der Grid Infrastruktur, eine wichtige Bedeutung zu, da diese intern alle Ressourcen steuert. Ressourcen können hierbei natürlich nicht nur die Oracle Prozesse (Datenbank, Listener, Virtuelle IP Adressen etc.) sein, sondern auch eigene Applikationen, die unter die Überwachung der Grid Infrastruktur resp. Clusterware gestellt werden. Dies kann von simplen Neustartanforderungen im Single Server Betrieb bis zu klassischen Failover Szenarien in Clusterumgebungen reichen. Diesem Aspekt trägt auch die Tatsache Rechnung, dass es seit einiger Zeit generische Applikations-Agenten (Siebel, Tomcat, GoldenGate, Apache, ...) für die Clusterware gibt und eine abgespeckte GI Installation auf der Oracle eigenen Middleware Hardware (Exalogic) läuft, um die Prozesse zu überwachen. Diese Cluster Ready Services werden vom Befehl "crsctl" gesteuert. Deshalb lohnt es sich dieses Utility mal genauer anzuschauen, zumal es einige Feinheiten enthält, die nicht direkt aus der Dokumentation bzw. Hilfe des Tools ersichtlich sind.

  • Leadership Tip&ndash;Vent Up!

    - by D'Arcy Lussier
    Leadership is difficult, for many reasons. One of those reasons is that we not only need to keep ourselves motivated when difficult or challenging times come, but we also need to motivate our teams and keep them focussed on the tasks at hand regardless of the mortars being rained down around them. Inexperienced (and experienced) leaders can fall into the “me-too” mentality – that is, the leader sees themselves as part of the team member instead of the leader of the team. Once a leader changes the teams view that he/she is a peer and not the leader, dynamics can change on the team. One of the biggest dangers is that the leader starts sharing frustrations, fears, concerns, etc. with the team that they’re supposed to be leading on to victory. This can destroy a team’s morale and productivity. One simple thing you can do to counter this is remember this rule when it comes to venting: Vent Up! Don’t vent sideways or down, vent up. Vent to the people above you – they’re the ones that tend to have the power to actually change things anyway. You as a leader stay healthy by getting your frustrations and concerns off your chest, your team is still insulated from it, and your superiors are aware of issues that need to be addressed or can coach you through the obstacles.

  • ASP.NET Website Security Tips and Tricks

    This is a tutorial on how to secure your ASP.NET Mono website. Securing an ASP.NET website that runs in Mono is very different from securing an ASP.NET website hosted in a Windows environment because an ASP.NET Mono website runs on a non-Windows server such as Apache or Lighttpd and on an operating system such as Linux Unix. Thus the principles of securing a website in Apache server can be applied to securing an ASP.NET that runs in Mono.... Comcast?

    - by merrillaldrich
    Over at erinstellato.com there is a great post this week about tips for new presenters. Ms. Stellato suggests, insightfully, that we record ourselves, which is really a fantastic piece of advice. What’s extra-cool is that today you don’t need any special equipment or expensive software to do just that. This week I “filmed” two run-throughs of my talk for SQL Saturday tomorrow. For me, the timing is the hardest thing – figuring out how much content I can really present in the time allowed without...(read more)

  • Tip: Regularily reset SharePoint Timer Service during development

    - by panjkov
    There is an interesting issue that can occur on development machines during development of SharePoint solutions that contain Site Templates or list templates in certain scenarios when site creation is not done manually, but using some kind of Custom Timer Job. The issue manifests in a way that even after retraction of old WSP and deployment of new WSP, even after performing IISRESET, sites created with new WSP don't have applied latest changes which are part of new WSP, but instead use (contain)...(read more)
