  • What are the common maintenance tasks on ubuntu?

    - by DaNieL
    When i was using windows, i used to run defrags, ccleaner and revouninstaller once a month to keep the system and the registry clean. I know ubuntu (and all linux distro) has a different system structure and doesnt need defrags, but i've heard there are some mainenance tasks that help to keep the system clean (for example, sudo apt-get clean or sudo apt-get autoremove) How many of those commands/software (and please explain what they do and if they can compromise the system stability) do you know and use regularly?

  • Mark Wilcox Discusses Privileged Account Management

Privileged accounts, if compromised, create a risk for fraud in the enterprise and as a result controlling access to privileged accounts is critical. The Oracle Privileged Account Manager solution can be deployed stand alone or in conjunction with the Oracle Governance Suite for a comprehensive solution. As part of the comprehensive platform, Privilege Account Manager is interoperable with the Identity suite. In addition, Privileged Account Manager can re-use Oracle Identity Manager connectors for propagating changes to target systems. The two are interoperable at the data level. I caught up with Mark Wilcox, Principal Product Manager of Oracle Privileged Account Manager and discussed with him the capabilities of the offering in this podcast. Click here to listen.

  • Configuring SQL Server Audit Logging with Powershell

    - by Jonathan Kehayias
    One of the standard configuration options that I set on all SQL Server installs is to log Failed Login Attempts to the SQL Server Error Log.  I recently inherited an environment that this option wasn’t standardized across all of the servers and needed to configure it for multiple servers in a scripted manner.  There are a couple of ways to handle this kind of task.  First I could log on to every server in SSMS, open the Server Properties, and set the option on the Security sheet for...(read more)

  • E-Business Suite Proactive Support - Workflow Analyzer

    - by Alejandro Sosa
    Overview The Workflow Analyzer is a standalone, easy to run tool created to read, validate and troubleshoot Workflow components configuration as well as runtime. It identifies areas where potential problems may arise and based on set of best practices suggests the Workflow System Administrator what to do when such potential problems are found. This tool represents a proactive way to verify Workflow configuration and runtime data to prevent issues ahead of time before they may become of more considerable impact on a production environment. Installation Since it is standalone there are no pre-requisites and runs on Oracle E-Business applications from 11.5.10 onwards. It is installed in the back-end server and can be run directly from SQL*Plus. The output of this tool is written in a HTML file friendly formatted containing the following on both workflow Components configuration and Workflow Runtime data: Workflow-related database initialization parameters Relevant Oracle E-Business profile option values Workflow-owned concurrent programs schedule and Workflow components status Workflow notification mailer configuration and throughput via related queues and table Workflow-relevant recommended and critical one-off patches as well as current code level Workflow database footprint by reading Workflow run-time tables to identify aged processes not being purged. It also checks for large open and closed processes or unhealthy looping conditions in a workflow process, among other checks. See a sample of Workflow Analyzer's output here.  Besides performing the validations listed above, the Workflow Analyzer provides clarification on the issues it finds and refers the reader to specific Oracle MOS documents to address the findings or explains the condition for the reader to take proper action. How to get it? The Workflow Analyzer can be obtained from Oracle MOS Workflow Analyzer script for E-Business Suite Workflow Monitoring and Maintenance (Doc ID 1369938.1) and the supplemental note How to run EBS Workflow Analyzer Tool as a Concurrent Request (Doc ID 1425053.1) explains how to register and run this tool as a concurrent program. This way the report from the Workflow Analyzer can be submitted from the Application and its output can be seen from the application as well.

  • Does tempdb Get Recreated From model at Startup?

    - by Jonathan Kehayias
    In my last post Does the tempdb Log file get Zero Initialized at Startup? I questioned whether or not tempdb is actually created from the model database or not at startup.  There is actually an easy way to prove that this statement, at least internally to the tempdb database is in fact TRUE.  Many thanks go out to Bob Ward (Blog | Twitter) for pointing this out after trading emails with him. To validate that tempdb is actually copied at startup from the model database, all that is necessary...(read more)

  • Can't create site connection in Contribute. Adminstrator account removed from domain

    - by tribus
    I have been tasked with administering several sites through Contribute. The previous administrator has since left and his domain account was removed. I believe I had been set up as an additional admin on these sites previously. However, when I attempt to create a connection through "My Connections" in Contribute using SFTP and my credentials, I get the following error: I have verified that I have read/write access to these sites through FTP. How can I take control of these sites through Contribute so that I can start administering them? Is this related to the removal of the previous admin's account?

  • Planning for Disaster

    There is a certain paradox in being advised to expect the unexpected, but the DBA must plan and prepare in advance to protect their organisation's data assets in the event of an unexpected crisis, and return them to normal operating conditions. To minimise downtime in such circumstances should be the aim of every effective DBA. To plan for recovery, It pays to have the mindset of a pessimist.

  • Prevent Apache restarting automatically after upgrading packages

    - by HorusKol
    Following on from an earlier question: Is there a way to download security updates and notify admin without installing the update? A large number of packages interact with Apache (especially PHP) such that security updates to those packages can cause the server to attempt to restart the service. While my earlier question was answered, I'm now thinking that I need a different solution. So - is there are way to allow security updates to be applied using apt, have an email sent to an administrator, and, most importantly, prevent services from being restarted at the end of the installation/update process? The administrator will then be able to log in and restart the service manually.

  • Create Outlook Appointments from PowerShell

    - by BuckWoody
    I've been toying around with a script to create a special set of calendar objects in Outlook that show when my SQL Server Agent Jobs are scheduled to run. I haven't finished yet, but I thought I would share the part that creates the Outlook Appointments.I have yet to fill a variable with the start and end times, and then loop through that to create the appointments. I'm thinking I'll make the script below into a function, and feed it those variables in a loop. The script below creates a whole new Calendar Folder in Outlook called "SQL Server Agent Jobs". I also use categories quite a bit, so you'll see that too. Caution: If you plan to play with this script, do it on an isolated workstation, not on your "regular" Outlook calendar. Otherwise, you'll have lots of appointments in there that you don't care about!  # Add a new calendar item to a new Outlook folder called "SQL Server Agent Jobs" $outlook = new-object -com Outlook.Application $calendar = $outlook.Session.folders.Item(1).Folders.Item("SQL Server Agent Jobs") $appt = $calendar.Items.Add(1) # == olAppointmentItem $appt.Start = [datetime]"03/11/2010 11:00" $appt.End = [datetime]"03/11/2009 12:00" $appt.Subject = "JobName" $appt.Location = "ServerName" $appt.Body = "Job Details" $appt.Categories = "SQL server Agent Job" $appt.Save()   Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script. If you experience blurry vision, indigestion or diarrhea during the operation of this script, see a physician immediately.   Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Backup those keys, citizen

    - by BuckWoody
    Periodically I back up the keys within my servers and databases, and when I do, I blog a reminder here. This should be part of your standard backup rotation – the keys should be backed up often enough to have at hand and again when they change. The first key you need to back up is the Service Master Key, which each Instance already has built-in. You do that with the BACKUP SERVICE MASTER KEY command, which you can read more about here. The second set of keys are the Database Master Keys, stored per database, if you’ve created one. You can back those up with the BACKUP MASTER KEY command, which you can read more about here. Finally, you can use the keys to create certificates and other keys – those should also be backed up. Read more about those here. Anyway, the important part here is the backup. Make sure you keep those keys safe! Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Statistical Sampling for Verifying Database Backups

    A DBA's huge workload can start to threaten best practices for data backup and recovery, but ingenuity, and an eye for a good tactic, can usually find a way. For Tom, the revelation about a solution came from eating crabs. Statistical sampling can be brought to bear to minimise the risk of faliure of an emergency database restore.

  • SQL Rally Presentations

    - by AllenMWhite
    As I drove to Dallas for this year's SQL Rally conference (yes, I like to drive) I got a call asking if I could step in for another presenter who had to cancel at the last minute. Life happens, and it's best to be flexible, and I said sure, I can do that. Which presentation would you like me to do? (I'd submitted a few presentations, so it wasn't a problem.) So yesterday I presented "Gathering Performance Metrics With PowerShell" at 8:45AM, and my newest presentation, "Manage SQL Server 2012 on Windows...(read more)

  • Interactive manifest editing with the Automated Installer Manifest Wizard

    - by Glynn Foster
    Oracle Solaris 11.2 adds a new Automated Installer (AI) Manifest Wizard to allow administrators to more easily create AI manifests for use in provisioning new client systems in the data center. The AI Manifest Wizard is a web web based interface that steps administrators through the basics of the AI manifest - target disks and layout selection, additional ZFS pools and datasets, IPS publisher and package selection, and the creation of any Oracle Solaris Zone virtual environments. The end result is an AI manifest without having to directly edit XML, and this can then be associated with an appropriate AI service. To get started, check out How To Create an Automated Installer Manifest with an Interactive Wizard

  • I want a non admin user to install software. What commands do I need to add to sudoers?

    - by Chance
    I want to edit the /etc/sudoers file so that a non-admin user can install software via the Software Center in Linux Mint 10. The reason for this is that I want a user to have the capability to install programs, but not make any other configuration changes to the system. So far I have the following (some of these may not make sense, I was just trying whatever I thought of) username ALL= /usr/bin/aptitude username ALL= /usr/bin/dpkg username ALL= /usr/local/bin/apt-get username ALL= /usr/lib/linuxmint/mintUpdate/mintUpdate.py username ALL= /usr/bin/software-center username ALL= /usr/bin/synaptic So far, it allows me to do updates without asking for my password, but it will not let me install software without entering an admin password. I am aware of this question, How can I set the Software Center to install software for non-root users?, but this goes the route of modifying the PolicyKit, whereas I'm interested in a sudo solution, because it seems a simpler way to go.

  • No more admin users?

    - by Kevin
    I am trying to install 12.04 on a Windows 7 machine. I used the Windows installer because I can't get the USB to work. When using the Windows installer it uses the user name on Windows 7. I wanted to change the admin name and set up some standard users. For some reason the admin password would not work and it changed all the users to 'standard.' Now I cannot add any users. Should I just reinstall?

  • Is it worth it to switch from home-grown remote command interface to using JMX

    - by Sam Goldberg
    Without knowing too much about JMX, I've always assumed that it would be the best approach for building in remote management to our standalone Java server application. Our server application has some minimal remote control capability, using text commands sent via TCP/IP socket to it. Using the home grown approach, it is fairly to add a new command. (Just create new command text, and the code to handle that in the message receiver). On the other hand, we have hardly implemented any commands, even though there are many things we would like to be able to execute remotely. I am trying to weigh the value of moving to incorporating JMX (learning it, and building the interfaces), versus just sticking with the home-grown approach. Does anyone have any experience or advice regarding changing an existing application to use JMX?
