  • Don't speak to the DBA while he/she is doing the job?!

    - by Uri Dimant
    Our DBA was very busy today, he helped out our developers to write efficient code,explained to the programmer how to launch the old DTS package on SQL Server 2005 and etc. You know how it is, someone comes in and asking the question and you answer the question at the same time you are busy to do something. So  today answering one of such questions he deleted by mistake very ctitical database. Fortunately, we had zero data loss,thanks to our backup/recovery strategy. I think that is acceptable to say that you are busy right now ,please ask the question later on, what do you think? How do you respond if someone asks you a queston while you are doing something on the server/database and etc.?   Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • On MySQL 5.1 for Windows, why can't I assign DBA role to the "root" user?

    - by djangofan
    On MySQL 5.1 for Windows, why can't I assign DBA role to "root" user? The MySQL Workbench allows me to add all the other roles except for DBA. Also, when I "alter schema" on any table, while logged in as root, I dont see all the tabs that show me all the database properties... I only see the first tab that allows me to change collation only. What is wrong with this picture? How do i give root all priveleges? I've tried a few variations of GRANT ALL PRIVILEGES etc. from the command line but nothing works. My root account is unable to alter column names, indexes, or options of any given table that I create. I can create tables and delete them but I can't alter them.

  • Die Fast / Flashback Recovery Area (FRA)

    - by Sebastian Solbach (DBA Community)
    In der Vergangenheit waren Informationen zur Fast Recovery Area (kurz FRA) bzw. Flashback Recovery Area, wie die FRA for 11gR2 benannt wurde, immer mal wieder in den einzelnen DBA Community Tipps enthalten, wenn dies gerade zum Thema passte oder für den Tipp relevant waren. Aus aktuellem Anlass haben wir uns deswegen entschlossen, die Informationen zur FRA im heutigen DBA Community Tipp  zu bündeln, damit man sofort eine Übersicht erhält und die automatischen Mechanismen innerhalb der FRA versteht.

  • SQL SERVER – Reseting Identity Values for All Tables

    - by pinaldave
    Sometime email requesting help generates more questions than the motivation to answer them. Let us go over one of the such examples. I have converted the complete email conversation to chat format for easy consumption. I almost got a headache after around 20 email exchange. I am sure if you can read it and feel my pain. DBA: “I deleted all of the data from my database and now it contains table structure only. However, when I tried to insert new data in my tables I noticed that my identity values starts from the same number where they actually were before I deleted the data.” Pinal: “How did you delete the data?” DBA: “Running Delete in Loop?” Pinal: “What was the need of such need?” DBA: “It was my development server and I needed to repopulate the database.” Pinal: “Oh so why did not you use TRUNCATE which would have reset the identity of your table to the original value when the data got deleted? This will work only if you want your database to reset to the original value. If you want to set any other value this may not work.” DBA: (silence for 2 days) DBA: “I did not realize it. Meanwhile I regenerated every table’s schema and dropped the table and re-created it.” Pinal: “Oh no, that would be extremely long and incorrect way. Very bad solution.” DBA: “I understand, should I just take backup of the database before I insert the data and when I need, I can use the original backup to restore the database. This way I will have identity beginning with 1.” Pinal: “This going totally downhill. It is wrong to do so on multiple levels. Did you even read my earlier email about TRUNCATE.” DBA: “Yeah. I found it in spam folder.” Pinal: (I decided to stay silent) DBA: (After 2 days) “Can you provide me script to reseed identity for all of my tables to value 1 without asking further question.” Pinal: USE DATABASE; EXEC sp_MSForEachTable ' IF OBJECTPROPERTY(object_id(''?''), ''TableHasIdentity'') = 1 DBCC CHECKIDENT (''?'', RESEED, 1)' GO Our conversation ended here. If you have directly jumped to this statement, I encourage you to read the conversation one time. There is difference between reseeding identity value to 1 and reseeding it to original value – I will write an another blog post on this subject in future.

  • Datenbank Speicherplatz überwachen mit dem Segment Advisor

    - by Ulrike Schwinn (DBA Community)
    Wie kritisch ist die Belegung des Speicherplatzes innerhalb der Tablespaces? Können vielleicht einige Segmente verkleinert bzw. reorganisiert werden, die unnötigen Platz verbrauchen? Um Antworten auf diese Fragen zu erhalten, gibt es die Möglichkeit unterschiedliche Data Dictionary Views wie DBA_SEGMENTS, DBA_EXTENTS und DBA_FREE_SPACE abzufragen bzw. Packages wie DBMS_SPACE zur detaillierten Analyse zu verwenden. Zusätzlich gibt es in der Oracle Datenbank spezielle mitgelieferte Advisors, die bei der Analyse des Speicherplatzes und der Objekte eine gewisse Unterstützung liefern können - den sogenannten Segment und den Compression Advisor. Der aktuelle Artikel in der DBA Community illustriert díe Verwendungsweise des Segment Advisors.

  • What are some good tips for a developer trying to design a scalable MySQL database?

    - by CFL_Jeff
    As the question states, I am a developer, not a DBA. I have experience with designing good ER schemas and am fairly knowledgeable about normalization and good schema design. I have also worked with data warehouses that use dimensional modeling with fact tables and dim tables. However, all of the database-driven applications I've developed at previous jobs have been internal applications on the company's intranet, never receiving "real-world traffic". Furthermore, at previous jobs, I have always had a DBA or someone who knew much more than me about these things. At this new job I just started, I've been asked to develop a public-facing application with a MySQL backend and the data stored by this application is expected to grow very rapidly. Oh, and we don't have a DBA. Well, I guess I am the DBA. ;) As far as designing a database to be scalable, I don't even know where to start. Does anyone have any good tips or know of any good educational materials for a developer who has been sort of shoved into a DBA/database designer role and has been tasked with designing a scalable database to support an application like this? Have any other developers been through this sort of thing? What did you do to quickly become good at this role? I've found some good slides on the subject here but it's hard to glean details from slides. Wish I could've attended that guy's talk. I also found a good blog entry called 5 Ways to Boost MySQL Scalability which had some good information, though some of it was over my head. tl;dr I just want to make sure the database doesn't have to be completely redesigned when it scales up, and I'm looking for tips to get it right the first time. The answer I'm looking for is a "list of things every developer should know about making a scalable MySQL database so your application doesn't perform like crap when the data gets huge".

  • Unified Auditing - Das neue Auditing in Oracle Database 12c

    - by Heinz-Wilhelm Fabry (DBA Community)
    In Datenbanken werden fast immer vor allem wichtige Informationen abgelegt. Der Zugriff darauf unterliegt in der Regel gesetzlichen oder betrieblichen Auflagen. Weil der Nachweis, dass diese Auflagen eingehalten werden, ausschliesslich über das Auditing möglich ist, ist eine Datenbank ohne Auditing eigentlich nicht vorstellbar. Ein Artikel der DBA Community hat sich bereits vor einiger Zeit mit den Möglichkeiten und Varianten des Auditierens in der Datenbankversion Oracle Database 11g beschäftigt. Der Artikel beschreibt das Auditing vom Default Auditing, mit dem zum Beispiel das Starten und Stoppen der Datenbank dokumentiert wird, bis hin zum Fine Grained Auditing (FGA), das sehr zielgerichtet DML Operationen erfasst. Er geht auch auf die unterschiedlichen Speichermöglichkeiten für die Audit Daten ein, auf die sogenannten audit trails: Neben der Variante, den audit trail in unterschiedlichen Tabellen der Datenbank (SYS.AUD$, SYS.FGA_LOG$, DVSYS.AUDIT_TRAIL$) abzulegen, wird dabei auf Betriebssystemdateien in einem Oracle proprietären oder im XML Format zurückgegriffen sowie auf die SYSLOGs oder EVENT LOGs der Betriebssysteme. Schaut man sich das alles an, kann man sicherlich feststellen, dass das Auditing über viele Jahre ständig an neue Anforderungen angepasst und erweitert wurde. Aber es ist damit auch nach und nach unübersichtlicher geworden. Das ist vor allem deshalb problematisch, weil das Ziel des Auditing nicht das unbegerenzte Sammeln von Informationen ist, sondern die Auswertung dieser Informationen. Darum wurden in der aktuellsten Datenbankversion, Oracle Database 12c, die unterschiedlichen audit trails zu einem einzigen audit trail zusammengeführt. Das Ergebnis wird als unified auditing bezeichnet. Die dazu nötige vollständige Überarbeitung der Architektur des Auditing Verfahrens bietet gleichzeitig die Gelegenheit, weitere Verbesserungen zu implementieren. Das betrifft sowohl die Performance als auch die Öffnung des gesamten Auditierens zur Nutzung durch diverse weitere Oracle Werkzeuge wie SQL*Loader und RMAN. Der folgende Artikel beschreibt, wie man das neue unified auditing einrichtet, wie man damit arbeitet und welche Vorteile es gegenüber dem 'alten' Auditing bietet Hier geht's zum Artikel.

  • How do I get into a career as a programmer/development DBA?

    - by markle976
    About 8-9 years ago I started getting into programming as a hobby. I started with my TI-86 calculator, and then moved into using Visual Basic. After about a year I started playing around with HTML and JavaScript. Then I discovered Flash; I programmed with Actionscript 2.0 for about 2 years which lead me to start using Coldfusion. After a while I realized that A) I am not a designer, and B) with the way that things were going with AJAX, .NET, and PHP there wasn’t much future in Coldfusion/Actionscript. I had been working mostly as an administrative assistant, but about 3-4 years ago I got a position where I would be doing some web development, and assisting the system admin with supporting windows desktop PCs. I have gotten some decent experience over the past few years, but it has been spread out in somewhat disparate areas: I spend about 40% of my time writing PHP/MySQL and HTML/CSS, etc. I spend about 20% of my time helping users with PC questions. I spend about 20% of my time doing administrative things (mail-merges, excel, etc). I spend about 20% of my time managing / creating reports from our Access Database. I have also taught myself many things on my own, and now have a beginner’s level understanding of things like: Windows Server, Java, Linux, Objective-C, SQL Server, C#, C++, Ruby, Mac OSX, VBA, VBScript, and basic IP networks. I feel like I am in a bit of a rut – I want to get my career moving, but I am not sure what I need to do. If I practice with C# and SQL Server Express for a year will that be enough to get me in the door somewhere? Would it be easier to get a position if I teach myself Linux/Apache since I have more experience with PHP/MySQL?

  • SQL SERVER – Caption the Cartoon Contest – Last 2 Days

    - by pinaldave
    Developer’s life is very interesting, we often want to start my day early at a job so we can go home early. However, the day never comes as the life of the developer is always about working late hours. If the developer goes to the office early – there are good chances that his co-workers will come late. Additionally, I am confident that there will be always something urgent for developers or DBA to solve right at the time they are ready to go home. This is the life of the developers!  Here is the interesting story of a DBA who was about to go to the home. He had to take his girlfriend to a movie and dinner in 30 minutes. However, his manager asks him to fix the performance related issues with their production server. In normal case, he had only two choices a) Job or b) Girlfriend. Well, our super hero DBA decided to use efficient tools and improve the performance of the production server in merely 30 minutes. When he was done, his manager was absolutely surprised by his efficiency and accuracy of the work. He asked him following question - Here is the contest – you need to guess what was the answer of our Super Hero DBA. If you guess the answer correct you may win Star Wars R2-D2 Inflatable Remote Controlled device. Additionally, if you Download DB Optimizer before Dec 8, 2012 – you will be eligible for USD 25 Amazon Gift Card (there are total 10 such awards). Please do not leave comments in this thread – to participate in the contest – please leave a comment here in the original contest page.

  • Oracle Key Vault - Hardware Security Modul für TDE und mehr

    - by Heinz-Wilhelm Fabry (DBA Community)
    Anfang August hat Oracle ein neues Produkt namens Oracle Key Vault (OKV) zum Einsatz freigegeben. Es handelt sich dabei um ein Hardware Security Modul (HSM) - also um ein Stück Hardware zum Speichern von Schlüsseln, Passwörtern und Dateien, die Schlüssel und Passwörter enthalten. Oracle Datenbank Installationen nutzen die zuletzt genannte Form des Speicherns von Passwörtern und Schlüsseln in Dateien für Oracle Advanced Security Transparent Data Encryption (TDE) und external password stores. Die Dateien werden in den Versionen 10 und 11 der Datenbank als Wallets bezeichnet, in der Version 12 als Keystores. Allerdings gibt es auch schon seit der Datenbankversion 11.2 beim Einsatz von TDE die Möglichkeit, statt der Wallets / Keystores HSMs einzusetzen. Da Oracle selbst kein eigenes HSM Produkt anbieten konnte, haben Unternehmenskunden dann auf Produkte anderer Anbieter zurückgegriffen. Das kann sich mit OKV nun ändern. Abhängig vom Bedrohungsszenario kann die Entscheidung gegen den Einsatz von Wallets / Keystores und für den Einsatz eines HSMs durchaus sinnvoll sein, denn ein HSM bietet mehr Sicherheit: Eine Betriebssystemdatei kann leichter gestohlen (kopiert) werden, als ein HSM, das in der Regel als speziell gesicherte Steckkarte in einem Rechner eingebaut ist oder als eigenes Gerät geschützt in einem Rechenzentrum steht. ein HSM kann anders als ein Wallet / Keystore systemübergreifend verwendet werden. Das erlaubt eine gemeinsame Nutzung von Schlüsseln - was wiederum zum Beispiel den Einsatz von TDE auf RAC Installationen perfekt unterstützt. ein HSM kann von mehreren Anwendungen genutzt werden. Das erleichtert das Konsolidieren und Verwalten von Passwörtern und Schlüsseln. Im aktuellen Tipp wird als Einführung in das neue Produkt dargestellt, wie OKV für TDE genutzt werden kann.
