• Friday Spotlight - October 25, 2013

  - by Chris Kawalek

  Happy Friday, everyone! Our spotlight this week is on a really cool technical tip on the Oracle Technology Network from Yuli Vasiliev called "How to Launch Linux Utilities from Oracle Database". From Yuli's introduction: "By wrapping a Linux utility in a script and using an external database table's preprocessor directive, you can launch the utility from within Oracle Database and have the utility's output be inserted into the external table. This allows you to do things such as query operating system data and then join it with data in Oracle Database." Head on over to OTN to read the full article. -Chris

• Error when setting Piwik analytics

  I've uploaded the latest version of Piwik unto my web server, which is hosted by go daddy.com, on a linux hosting plan. I'm setting it up (accessing it from my browser as instructed) and I have the "Piwikinstallation" page open on step 3 (database set-up ) of 9. I don't know what to imput in the field "database server"... the default is the number 127.0.0.1 When I leave that input as is, and click "Next" leaving the gives the error: "Error when trying to connect to database server: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 111" and changing that input to "localhost" gives me another error: "Error when trying to connect to database server:SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)"

• EPM 11.1.2.2 Architecture: Financial Performance Management Applications

  - by Marc Schumacher

   Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

• Rule Engine in .net

  - by user641812

  I have to import data from excel to SQL database. Excel data contains various parameters and there value like P1,P1,P4,P5 etc. I have to apply business rules Like if( P1 100 and P1 < 200) then insert the record in database. Similarly in some cases string values are also validated. Can I have any open source rule engine that contains UI to change , add , delete the rules. Am using C# to read the excel and and insert the records One more thing which is best approach: Read excel first and store every record as an object in a collection, then iterate through the collection, apply business rules on every object and then insert record in the database Or Read one record from excel apply business rule and then insert record in the database. Repeat the process for whole excel.

• Tales of a corrupt SQL log

  Warning: Im a simple dev, not an all powerful DBA with godly powers. This morning, one of my sites was down and DNN reported a problem with the database.  A quick series of tests revealed that the culprit was a corrupted log file. Easy fix I said, I have daily backups so its just a mater of restoring a good copy of the database and log files.  Well, I found out thats not exactly true.  You see, for this database, I have daily file backups and these are not database backups created...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• PECL OCI8 2.0 Production Release Announcement

  - by cj

  The PHP OCI8 2.0.6 extension for Oracle Database is now "production" status. The source code is available on PECL. This can be used immediately to update your OCI8 extension in PHP 5.2 and later versions. The extension compiles with Oracle 10.2 or later client libraries. Oracle's standard cross-version database connectivity applies. OCI8 2.0 and PHP 5.5.5 RPMs for Oracle and Red Hat Linux are available from oss.oracle.com. Windows DLLs are available on PECL for PHP 5.3, PHP 5.4 and PHP 5.5. OCI8 2.0 source code will also be automatically included in the next major version of PHP. New Functionality Oracle Database 12c Implicit Result Set support. IRS's make it easy to pass query results back from stored PL/SQL procedures or anonymous PL/SQL blocks. Individual IRS statement resources, each corresponding to a single query, can be obtained with the new function oci_get_implicit_resultset(). These 'child' statement resources can be passed to any oci_fetch_* function. See Using PHP and Oracle Database 12c Implicit Result Sets and the PHP Manual: oci_get_implicit_resultset(). DTrace Dynamic Trace static probes. This well respected DTrace tracing framework is available on a number of platforms, including Oracle Linux. PHP OCI8 static user-space probes can be enabled with PHP's --enable-dtrace configuration option. See Using PHP DTrace on Oracle Linux. Documentation is also available in the PHP Manual OCI8 and DTrace Dynamic Tracing Improved Functionality Using oci_execute($s, OCI_NO_AUTO_COMMIT) for a SELECT no longer unnecessarily initiates an internal ROLLBACK during connection close. This can improve overall scalability by reducing "round trips" between PHP and the database. Changed Functionality PHP OCI8 2.0's minimum pre-requisites are now PHP 5.2 and Oracle client library 10.2. Later versions of both are usable and, in fact, recommended. Use the older PHP OCI8 1.4.10 extension when using PHP 4.3.9 through to PHP 5.1.x, or when only Oracle Database 9.2 client libraries are available. oci_set_*($connection, ...) meta data setting call error handling is fixed so that oci_error($connection) works for these calls. Note: The old, deprecated function aliases like ocilogon still exist but are not recommended for new applications. Phpinfo() Changes Some cosmetic changes were made to the output of php --ri oci8 and the phpinfo() function. The oci8.event and oci8.connection_class values are now shown only when the Oracle client libraries support the respective functionality. Connection statistics are now in a separate phpinfo() table. Temporary LOB and Collection support status lines in phpinfo() output were removed. These two features have always been enabled since 2007. Oci_internal_debug() Changes The oci_internal_debug() function is now a no-op. Use PHP's --enable-dtrace functionality with DTrace or SystemTap instead. References OCI8 Extension source code and Windows DLLs http://pecl.php.net/package/oci8 Oracle Linux RPMs oss.oracle.com PHP Manual for OCI8 OCI8 and DTrace Dynamic Tracing Oracle OpenWorld Conference paper What's New in Oracle Database 12c for PHP

• SQL Server 2008 CPU usage goes to 100% - troubleshooting help needed?

  - by Ali

  I have a fairly powerful database server having SQL Server 2008 R2 installed. There is only one database on it which is being accessed from 2 servers (around 5/6 applications). The problem is as soon as applications start pointing to the database, system's CPU usage goes upto 100% with sqlserver itself using 95+%. I have checked profiler, there aren't any heavy queries running there. I have checked active connections, they are hardly 150. Still CPU usage is around 100% and applications are experiencing slow response/connection to database server are getting refused. Database grus, I really need some ideas here. Thanks.

• Adding Column to a SQL Server Table

  - by Dinesh Asanka

  Adding a column to a table is  common task for  DBAs. You can add a column to a table which is a nullable column or which has default values. But are these two operations are similar internally and which method is optimal? Let us start this with an example. I created a database and a table using following script: USE master Go --Drop Database if exists IF EXISTS (SELECT 1 FROM SYS.databases WHERE name = 'AddColumn') DROP DATABASE AddColumn --Create the database CREATE DATABASE AddColumn GO USE AddColumn GO --Drop the table if exists IF EXISTS ( SELECT 1 FROM sys.tables WHERE Name = 'ExistingTable') DROP TABLE ExistingTable GO --Create the table CREATE TABLE ExistingTable (ID BIGINT IDENTITY(1,1) PRIMARY KEY CLUSTERED, DateTime1 DATETIME DEFAULT GETDATE(), DateTime2 DATETIME DEFAULT GETDATE(), DateTime3 DATETIME DEFAULT GETDATE(), DateTime4 DATETIME DEFAULT GETDATE(), Gendar CHAR(1) DEFAULT 'M', STATUS1 CHAR(1) DEFAULT 'Y' ) GO -- Insert 100,000 records with defaults records INSERT INTO ExistingTable DEFAULT VALUES GO 100000 Before adding a Column Before adding a column let us look at some of the details of the database. DBCC IND (AddColumn,ExistingTable,1) By running the above query, you will see 637 pages for the created table. Adding a Column You can add a column to the table with following statement. ALTER TABLE ExistingTable Add NewColumn INT NULL Above will add a column with a null value for the existing records. Alternatively you could add a column with default values. ALTER TABLE ExistingTable Add NewColumn INT NOT NULL DEFAULT 1 The above statement will add a column with a 1 value to the existing records. In the below table I measured the performance difference between above two statements. Parameter Nullable Column Default Value CPU 31 702 Duration 129 ms 6653 ms Reads 38 116,397 Writes 6 1329 Row Count 0 100000 If you look at the RowCount parameter, you can clearly see the difference. Though column is added in the first case, none of the rows are affected while in the second case all the rows are updated. That is the reason, why it has taken more duration and CPU to add column with Default value. We can verify this by several methods. Number of Pages The number of data pages can be obtained by using DBCC IND command. Though, this an undocumented dbcc command, many experts are ok to use this command in production. However, since there is no official word from Microsoft, use this “at your own risk”. DBCC IND (AddColumn,ExistingTable,1) Before Adding the Columns 637 Adding a Column with NULL 637 Adding a column with DEFAULT value 1270 This clearly shows that pages are physically modified. Please note, a high value indicated in the Adding a column with DEFAULT value  column is also a result of page splits. Continues…

• Connection to mysql server in SYN_SENT

  - by Sunil

  We are facing a strange problem from last few days between our application server and database server(Mysql): connection to database server from application server hangs in SYN_SENT state and after that we are not able to make any connection to database server on mysql port(3306). When we checked the netstat output on database server its in SYN_RECV state. What I can figure out is mysql server is receiving the SYN request and responding also and its not reaching to the client hence SYN_RECV at server side and SYN_SENT at client side. I think SYN_SENT state should go after some time and because of this other db connection attempts to same server should not hang. Does anybody have any idea how can we resolve this issue? Out setup details : Application server: RHEL 5.4, kernel-release = 2.6.18-164.el5, x86_64 Database server: Mysql Version : 5.1.49 RHEL 5.4, kernel-release = 2.6.18-164.el5, x86_64

• SQL SERVER – DELETE, TRUNCATE and RESEED Identity

  - by pinaldave

  Yesterday I had a headache answering questions to one of the DBA on the subject of Reseting Identity Values for All Tables. After talking to the DBA I realized that he has no clue about how the identity column behaves when there is DELETE, TRUNCATE or RESEED Identity is used. Let us run a small T-SQL Script. Create a temp table with Identity column beginning with value 11. The seed value is 11. USE [TempDB] GO -- Create Table CREATE TABLE [dbo].[TestTable]( [ID] [int] IDENTITY(11,1) NOT NULL, [var] [nchar](10) NULL ) ON [PRIMARY] GO -- Build sample data INSERT INTO [TestTable] VALUES ('val') GO When seed value is 11 the next value which is inserted has the identity column value as 11. – Select Data SELECT * FROM [TestTable] GO Effect of DELETE statement -- Delete Data DELETE FROM [TestTable] GO When the DELETE statement is executed without WHERE clause it will delete all the rows. However, when a new record is inserted the identity value is increased from 11 to 12. It does not reset but keep on increasing. -- Build sample data INSERT INTO [TestTable] VALUES ('val') GO -- Select Data SELECT * FROM [TestTable] Effect of TRUNCATE statement -- Truncate table TRUNCATE TABLE [TestTable] GO When the TRUNCATE statement is executed it will remove all the rows. However, when a new record is inserted the identity value is increased from 11 (which is original value). TRUNCATE resets the identity value to the original seed value of the table. -- Build sample data INSERT INTO [TestTable] VALUES ('val') GO -- Select Data SELECT * FROM [TestTable] GO Effect of RESEED statement If you notice I am using the reseed value as 1. The original seed value when I created table is 11. However, I am reseeding it with value 1. -- Reseed DBCC CHECKIDENT ('TestTable', RESEED, 1) GO When we insert the one more value and check the value it will generate the new value as 2. This new value logic is Reseed Value + Interval Value – in this case it will be 1+1 = 2. -- Build sample data INSERT INTO [TestTable] VALUES ('val') GO -- Select Data SELECT * FROM [TestTable] GO Here is the clean up act. -- Clean up DROP TABLE [TestTable] GO Question for you: If I reseed value with some random number followed by the truncate command on the table what will be the seed value of the table. (Example, if original seed value is 11 and I reseed the value to 1. If I follow up with truncate table what will be the seed value now? Here is the complete script together. You can modify it and find the answer to the above question. Please leave a comment with your answer.

• You Don't Want to Meet Orgad Kimchi in a Dark Alley

  - by rickramsey

  source Do you remember what those bad guys in the old Charles Bronson films looked like? They looked like Orgad Kimchi, that's what they looked like. When I met him at Oracle OpenWorld 2012, I realized I didn't want to meet him in the wrong alleyway of Budapest after dark. Neither do old versions of Oracle Solaris, which Orgad bends to his will with as much ease as he probably bends stray tourists to his will in Budapest, Kandahar, or Dagestan. How Orgad Made Oracle Database Migrate from Oracle Solaris 8 to Oracle Solaris 11 In this article, which we liked so much we reprinted it from his blog (please don't tell him!), Orgad explains how he head-butted an Oracle Database into submission. The database thought it was safe running in Oracle Solaris 8, but Orgad dragged its whimpering carcas into Oracle Solaris 11. How'd he do that? Well, if you had met Orgad in person, you wouldn't ask that question. Because you'd know he could have simply stared at it, and the database would have migrated on its own. But Orgad didn't do that. Instead, he stuffed an Oracle Solaris 8 Physical-to-Virtual (P2V) Archiver Tool into his leather trench coat, the one with the special pockets sown in by the East German Secret Police for several Uzis and their ammo, and walked into his data center in a way that reminded the survivors of this clip from Matrix Reloaded. The end result? The Oracle Database 10.2 that was running on Oracle Solaris 8 is now running inside a Solaris 10 branded zone in Oracle Solaris 11. With no complaints. Don't make Orgad angry.

• Is reliance on parametrized queries the only way to protect against SQL injection?

  All I have seen on SQL injection attacks seems to suggest that parametrized queries, particularly ones in stored procedures, are the only way to protect against such attacks. While I was working (back in the Dark Ages) stored procedures were viewed as poor practice, mainly because they were seen as less maintainable; less testable; highly coupled; and locked a system into one vendor; (this question covers some other reasons). Although when I was working, projects were virtually unaware of the possibility of such attacks; various rules were adopted to secure the database against corruption of various sorts. These rules can be summarised as: No client/application had direct access to the database tables. All accesses to all tables were through views (and all the updates to the base tables were done through triggers). All data items had a domain specified. No data item was permitted to be nullable - this had implications that had the DBAs grinding their teeth on occasion; but was enforced. Roles and permissions were set up appropriately - for instance, a restricted role to give only views the right to change the data. So is a set of (enforced) rules such as this (though not necessarily this particular set) an appropriate alternative to parametrized queries in preventing SQL injection attacks? If not, why not? Can a database be secured against such attacks by database (only) specific measures? EDIT Emphasis of the question changed slightly, in the light of the initial responses received. Base question unchanged. EDIT2 The approach of relying on paramaterized queries seems to be only a peripheral step in defense against attacks on systems. It seems to me that more fundamental defenses are both desirable, and may render reliance on such queries not necessary, or less critical, even to defend specifically against injection attacks. The approach implicit in my question was based on "armouring" the database and I had no idea whether it was a viable option. Further research has suggested that there are such approaches. I have found the following sources that provide some pointers to this type of approach: http://database-programmer.blogspot.com http://thehelsinkideclaration.blogspot.com The principle features I have taken from these sources is: An extensive data dictionary, combined with an extensive security data dictionary Generation of triggers, queries and constraints from the data dictionary Minimize Code and maximize data While the answers I have had so far are very useful and point out difficulties arising from disregarding paramaterized queries, ultimately they do not answer my original question(s) (now emphasised in bold).

• Alternatives for 'egrep -o "success|error|fail" <filename> | sort | uniq -c'

  - by Wolfy

  I sometime need to check some logs and I do this with this command: egrep -o "success|error|fail" <filename> | sort | uniq -c Sample input: test error on line 10 test connect success test insert success test started at 00:00 test delete fail Sample output: 1 error 1 fail 2 success I would like to know if someone knows a way to do this with a shorter command? Before you ask why I would like to do this with an different command... No special reason, I'm just curious :)

• VSDB to SSDT Series : Introduction

  - by Etienne Giust

  At the office, we extensively use VS2010 SQL Server 2008 Database Projects and SQL Server 2008 Server Projects  in our Visual Studio 2010 solutions. With Visual Studio 2012, those types of projects are replaced by the  SQL Server Database Project  using the SSDT (SQL Server Data Tools) technology. I started investigating the shift from Visual Studio 2010 to Visual Studio 2012 and specifically what needs to be done concerning those database projects in terms of painless migration, continuous integration and standalone deployment. I will write my findings in a series of 4 short articles: Part 1 will be about the database projects migration process and the cleaning up that ensues Part 2 will be about creating SQL Server 2008 Server Projects equivalents with the new SSDT project type Part 3 will introduce a replacement to the vsdbcmd.exe command used for deployment in our continuous integration process Part 4 will explain how to create standalone packages of SSDT projects for deployment on non accessible servers (such as a production server)
