DB2 Version 10.1 for Linux, UNIX, and Windows
DB2 Version 10.1 for Linux, UNIX, and Windows
You can use the db2prereqcheck command to check the software and firmware prerequisites of a specific DB2® version.
With the db2prereqcheck command, you can determine if your system satisfies the DB2 installation prerequisite without having to start the installation of a specific DB2 version. This command checks prerequisites such as operating system level, Linux distribution, AIX® Technology Level, C library & runtime patch, Client, uDAPL, GPL or DB2 pureScale® specific requirements.
The DB2 product comes with the db2prereqcheck binary and the DB2prereqs.xml file in the cfg folder. The DB2prereqs.xml file contains the prerequisite from Version 9.8 Fix Pack 2 to Version 10.1, and the contents should not be modified. You must run the db2prereqcheck command in the directory where the installation image is located.
For DB2 Version 10.1 Fix Pack 1 or earlier, you must extract the binary file and the XML file to your temporary folder in your desktop before you can run the db2prereqcheck command. You do not need to extract the files if your operating system has DB2 product installed. You need read and write access to the system to run db2prereqcheck command (that is, read access for reading in DB2prereqs.xml and write access to generate the output file).
If you run the db2prereqcheck command with no parameters, it determines whether the system meets the prerequisites for all the DB2 releases and fix packs that are defined in the resource XML file.
You can check prerequisites requirement for the latest DB2 version, a specific DB2 version, generate a report file, and more with the db2prereqcheck command.
To check the prerequisites for the latest DB2 version that is defined in the resource XML file, run db2prereqcheck command with -i parameter. For example,
$ ./db2prereqcheck -iTo check whether the system meets the prerequisite for the specific DB2 version that is defined in the resource XML file, run db2prereqcheck command with -v <version number> parameter. For example,
$ ./db2prereqcheck -v 10.1.0.0 To generate a report file containing validation information and output from the db2prereqcheck command (including a summary section listing all failing tests), use the -o <filename> parameter. Specify the full report filename path to generate the report in another directory. The prerequisites for installing the DB2 product will only be displayed on the command screen without the -o <filename> parameter.
$ ./db2prereqcheck -i -o report.rptThe default XML file (with file path : DB2 installation/cfg/DB2prereqs.xml) will be used if the -f parameter is not specified. If this default XML file is not found, -f <filename> can be used to specify the XML file.
$ ./db2prereqcheck -i -f ./newDB2prereqs.xmlTo check whether the system meets the basic pureScale prerequisites for a specific DB2 version, run the db2prereqcheck command with -p ,-v <version number>, -h1 <set of hosts (member and cf hosts)>, -dl <one ore more shared disks for GPFS file system>, and -iu <pureScale instance userid> parameters. For example,
$ ./db2prereqcheck -p -v 10.1.0.0 -hl <host1,host2..> -dl <shared_disk1,shared_disk2..> -iu <user>To check whether the system meets the comprehensive pureScale prerequisites for a specific type of network configuration (Linux operating systems only) and for a specific DB2 version, run the db2prereqcheck command with -p ,-v <version number>, -h1 <set of hosts(member and cf hosts)>, -dl <one ore more shared disks for GPFS file system>, -iu <pureScale instance userid>, and -nl <list of networks> parameters. For example,
$ ./db2prereqcheck -p -v 10.1.0.0 -hl <host1,host2..> -dl <shared_disk1,shared_disk2..> -iu <user> -nl <netname1,netname2..>$ ./db2prereqcheck -i -p $ ./db2prereqcheck -i -p -t <network configuration type>If the db2prereqcheck command indicates that the system fails to meet the prerequisite, DBT3507E, for example,
