IBM DB2 Express-C for Linux HOWTO Ian Hakes Revision History Revision 2.0 2007-07-15 Revised by: idmh Complete re IBM DB2 Express-C for Linux. Installing db. 2 9 express- c on a headless Ubuntu/Redhat (RHEL) box with db. Ok, so after posting my summarized HOW TO guide on how to manually install and uninstall DB2 9 express- c via db. That being using response files with the db. Just to note, there are two ways you can install DB2 via the command line without any sort of x- server. Via the process described below in detail below by using a response file and db. DB2 V9.7 on RedHat 5.4 install. 1 from the IBM website DB2 9.7 express C. Open the <filename>~/cdrom/db2/linux/db2. Install DB2 V10 and Data Studio V3 under Linux (Ubuntu). DB2 version of DB2 Express-C V10.1 Linux. For our current pet project we've decided to use DB2 Express-C as. Db2 Express C TutorialVia the db. 2. This path will be referred to throughout the rest of this document as DB2. DIRf) This article only shows configuring a single DB2 instance called db. You can certainly change MORE options than what I specifically call out below in the response file editing section (such as the install path etc), however I am just pointing out the options you MUST change to get the install rolling with a basic install. INSTALLING WITH DB2. SETUP AND A RESPONSE FILEThe following instructions are taken from the official document located here. Login as root. As root, open up /etc/services and add the following line at the end of the file db. Its time to party and get going on this file so lets move on to the next bullet. An IMPORTANT note, any line with a * or # is a COMMENT within the file and is not processed. Before we continue, click here to view a handy reference that contains descriptions of all the configurable settings within a response file. Scroll down to LIC. Now given this is a headless machine you are installing to, you probably only care about uncommenting the DB2. You will need to evaluate each one to see if you want it installed. Again, given you are on a headless machine, you probably want to skipeverything that is a GUI tool. The item I kept was TEXT. This is an important one as here is where we specify instance information and the users that are to be created. Instance Creation Settings. Ok, we are still within the response file and you should be at the “Instance Creation Settings” section. This section contains the parameters for the db. In this section you will see a bunch of db. SOMEPROPNAME settings. I am only going to point out the ones you might consider changing below, the defaults should be fine for you. GROUP. This is optional of course but just my preference. HOME! This section contains the parameters for the db. In this section you will see a bunch of db. SOMEPROPNAME settings. I am only going to point out the ones you might consider changing below, the defaults should be fine for you. FENCED. This is optional of course but just my preference. FENCED. If you just want to get up running, you can skip this and they can be changed later, however you will need to know what you are doing as these are tweaks to the instance for performance and other optimizations. Skip mucking with this for now. Administration Server Creation Settings. Yes it continues, but this is an important one. This section covers the administration server and our DAS user which we are calling db. I am only going to point out the ones you might consider changing below, the defaults should be fine for you. DAS. Again this is a configuration setting section however you may want to change certain ones, I will point out the ones I changed for my basic install needs. DB2. CODEPAGE I set mine to the value “1. UTF- 8. DB2. COMM = TCPIPDatabase Settings and the remainder of the file (skip it)This section pertains to any “default” databases that you want the installer to automatically create and some other sections which are not necessary at this point. I skip these remaining sections. MOVING ON TO THE INSTALLOk, so if you have not already done so, save the my- db. Execute ./db. 2setup - r /tmp/db. This will fire off the installation. If there are any errors in your response file, you should get them now, and can correct them, re- run if necessary. Assuming that db. DB2 is now running on this box and you are good to go to begin creating databases etc. Remember to adjust your iptables firewall rules accordingly per your requirements to restrict access to only the hosts you want to permit. VERIFYHey, lets create a basic database and verify we can use it to see that DB2 works. Login as db. 2inst. Connect with db. 2 connect to bitsoi user db. Enter the password. You are now connected if you seee the “database connection information” output. Fire up the CLP with db. At the prompt type create table my. Test (name varchar(1. If successful, insert a record with insert into my. Test (name) values ('bitsofinfo')Select it with select * from my. Test. Yeah, it works, exit with a quit and when back at the command line type db. UNINSTALLThere is a method to uninstall DB2 via a response file as well. See the official DB2 document here. BEFORE doing this, you STILL have to drop your db. Login as rootcd /tmp/db. This is the uninstall response file. To remove everything just uncomment the first REMOVE. I guess the response file uninstall method gives you better control over what you want removed. Your average joe, maybe a new user wanting to try out DB2, who needs to install DB2 on a headless box, is going to start by reading the “Installing DB2 servers (Linux and UNIX)” document in the IBM docs. They will quickly see the following note: The DB2 Setup wizard is a graphical installer. You must have X windows software capable of rendering a graphical user interface for the DB2 Setup wizard to run on your machine. Ensure that the X windows server is running. Ensure that you have properly exported your display. For example, export DISPLAY=9. Ok great, but hey, wouldn’t it be great if this document stated something to the effect of: “If you X windows software is not available you can either manually install via the db. Which unfortunately is not really titled appropriately (nor linked to from the db. I can install without a GUI from the command line”. The net result? A new user to DB2 express c, might just bail immediately and go with another piece of database software, because they can install much easier right out of the box on a headless machine without laboring through a dozen or so online HTML documents. Also don’t forget that since they are installing headless, they can’t even view those if the only machine they have is the box they are installing on. Not likely, but possible, and I for one would have no desire to bust out lynx or elinks etc. DB2 Quick Guide. This chapter describes history of DB2, its versions, editions and their respective features. DB2 is a database product from IBM. It is a Relational Database Management System (RDBMS). DB2 is designed to store, analyze and retrieve the data efficiently. DB2 product is extended with the support of Object- Oriented features and non- relational structures with XML. Initially, IBM had developed DB2 product for their specific platform. The following table shows DB2 server editions and their features: This chapter describes installation steps of DB2 server. You can download the DB2 Server trial version or purchase the product license from www. There are two separate DB2 servers available for downloading, depending upon the size of operating system, on which it is intended to execute. For example, if you want to download a DB2 server for 3. Linux or UNIX operating system, then you need to download a 3. DB2 server. The same applies for 6. DB2 server. Before installing the DB2 server, your system needs to get ready with the required software on it. For Linux, you need to install “libstdc++6. Before installing DB2 Server, you need to verify if your system is compatible with the DB2 server. For confirming the compatibility, you need to call 'db. Open the Terminal and set the db. CD < DB2 installation folder> ” command. Then type “./db. 2prereqcheck” command, which confirms the compatibility of your system with DB2 server. Figure- 1 shows the compatibility requirements of Linux operating system and hardware system. Open the terminal. Login as root user. Open DB2 Installation folder. Type “./db. 2setup” and press Enter. This process will start execution of DB2 server setup. Type “./db. 2setup” and press Enter on root terminal to start setup process of DB2 Server. On doing so, the “Set up Launch Pad” screen appears. Select option “DB2 Advanced Enterprise Server Edition”. Select “Install New” Button. A new frame appears with name “DB2 setup wizard”. Select “I accept the terms. Enter your password for “dasusr. Your password can be identical to username so that it is convenient to remember.)On the following screen, the setup asks you for creation of DB2 Server Instance. Here, it is creating a DB2 instance with name “db. The next screen asks you the number of partitions you require for your default instance. You have a choice of “single or Multiple” partitions. Select “single partition instance”. Click “next”. On the next screen, the setup asks you for authentication for DB2 instance being created. Here, by default username is created as “db. You can enter password same as username. Click “Next”. On the next screen, the setup asks to enter authentication information for “db. Here, you can enter password same as username. Click “Next”. On the next screen, you can select “Do not setup your db. Click ”Next”. The next screen shows you the information about db. Click “Finish”. The DB2 Installation procedure is complete at this stage. You need to verify the installation of DB2 server for its usefulness. On completing the DB2 Server installation, logout from current user mode and login to “db. In “db. 2inst. 1” user environment, you can open terminal and execute the following commands to verify if your db. This command shows the current version and service level of the installed DB2 product for current instance. This command shows all the license related information of our DB2 Product. Command mode: In this mode, each command and SQL statement must be prefixed by “db. For example, query “db. Interactive input mode: you can launch this mode by using the “db. Here, you can pass SQL statements without prefix. For example, “activate database sample”. Batch mode: Here, you need to create a script file, which contains all SQL queries of requirements and save the file with “. You can call this in command line using syntax “db. DB2 Instance. Introduction. An Instance is a logical environment for DB2 Database Manager. Using instance, you can manage databases. The contents of Instance directory are: Database Manager Configuration file. System Database Directory. Node Directory. Node Configuration File . It is not possible to change the location of Instance directory after its creation. In an instance, each database has a unique name, its own set of catalog tables, configurations files, authorities and privileges. Architecture of instance in DB2 product. Multiple instances. You can create multiple instances in one DB2. Server on Linux, UNIX and Windows. It is possible to install multiple DB2. Servers on a physical machine. Creating instance on Linux. You can create multiple instances on Linux and UNIX if DB2 Server is installed as root user. An instance can run simultaneously on Linux and UNIX independently. You can work within a single instance of the database manager at a time. An Instance folder contains database configuration files and folders. The Instance directory is stored at different locations on Windows depending on the operating system versions. Listing instances. The following command is used to list instances: db. This command lists all the instances that are available on a system. Syntax. Example. Before this, you need to run “set instance”. Syntax. Example. Instance id is not a root id or a root name. Here are the steps to create a new instance: Step. Create an operating system user for instance. Syntax. useradd - u < ID> - g < group name> - m - d < user location> < user name>. Example: . In the syntax given below, . The following syntax . Before executing this command, you need to stop the instance database manager using “db. The syntax below “inst. In the following syntaxes, “inst. When you create a database, all the details about database are stored in a database directory, such as details of default storage devices, configuration files, and temporary tables list etc. Partition global directory is created in the instance folder. This directory contains all global information related to the database. This partition global directory is named as NODExxxx/SQLyyy, where xxxx is the data partition number and yyy is the database token. In the partition- global directory, a member- specific directory is created. This directory contains local database information. The member- specific directory is named as MEMBERxxxx where xxxx is a member number. DB2 Enterprise Server Edition environment runs on a single member and has only one member specific directory. This member specific directory is uniquely named as MEMBER0. Partitioned global directory. Directory Location : < instance> /NODExxx/SQLxxx. The partition- global directory contains database related files as listed below. Global deadlock write- to- file event monitoring files. Table space information files . The detailed deadlock events monitor files are stored in the database directory of the catalog node in case of ESE and partitioned database environment. Creating database. You can create a database in instance using the “CREATE DATABASE” command. All databases are created with the default storage group “IBMSTOGROUP”, which is created at the time of creating an instance. In DB2, all the database tables are stored in “tablespace”, which use their respective storage groups. The privileges for database are automatically set as PUBLIC . To create the database using user- defined database location, the following procedure is followed: Syntax: . Using the command line processor, you can use these commands. Database Manager Configuration Parameters. Syntax: . This command can delete all its objects, table, spaces, containers and associated files. Syntax: . The purpose of bufferpools is to cache table and index data from disk. All databases have their own bufferpools. A default bufferpool is created at the time of creation of new database. It called as “IBMDEFAULTBP”. Depending on the user requirements, it is possible to create a number of bufferpools. In the bufferpool, the database manager places the table row data as a page. This page stays in the bufferpool until the database is shutdown or until the space is written with new data. The pages in the bufferpool, which are updated with data but are not written onto the disk, are called “Dirty” pages. After the updated data pages in the bufferpool are written on the disk, the bufferpool is ready to take another data. Relationship between tablespaces and bufferpools. Each table space is associated with a specific buffer pool in a database. One tablespace is associated with one bufferpool. The size of bufferpool and tablespace must be same. Multiple bufferpools allow you to configure the memory used by the database to increase its overall performance. Bufferpool sizes. The size of the bufferpool page is set when you use the “CREATE DATABASE” command. If you do not specify the page size, it will take default page size, which is 4. KB. Once the bufferpool is created, it is not possible to modify the page size later. Listing the available bufferpools in the current database directory. Syntax: . It can be used to organize data in a database into logical storage group which is related with where data stored on a system. This tablespaces are stored in database partition groups. Benefits of tablespaces in database. The table spaces are beneficial in database in various ways given as follows: Recoverability: Tablespaces make backup and restore operations more convenient. Using a single command, you can make backup or restore all the database objects in tablespaces. Automatic storage Management: Database manager creates and extends containers depending on the needs. Memory utilization: A single bufferpool can manage multiple tablespaces. You can assign temporary tablespaces to their own bufferpool to increase the performance of activities such as sorts or joins. Container. Tablespaces contains one or more containers. A container can be a directory name, a device name, or a filename. In a database, a single tablespace can have several containers on the same physical storage device.
