For additional information on changes to the product, review the product Release Notes: X:\RELEASE.TXT Windows 95/98/NT/2000/2003/Me/XP installation notes 2.1 Prerequisites This FixPak requires one of the following DB2 products: DB2 UDB Version 7.2 for Windows, or DB2 UDB Version 7.1 for Windows with DB2 V7 FixPak 3 or higher To determine the version and level of the currently installed DB2 product, type regedit from an MS-DOS prompt and check the following values under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\IBM\DB2\\CurrentVersion. The values should be the following: Version "7" Release "1" Modification "3" 2.2 Installing non-English versions of DB2 on Windows 95 You will need to manually upgrade WinSock to version 2 if you are installing DB2 on a Windows 95 computer that uses a non-English language. The English-language version of DB2 will upgrade WinSock 1.1 to Version 2 automatically during the installation process. Non-English versions of DB2 will fail to install if WinSock is not upgraded prior to installation. If you are installing DB2 on a non-English Windows 95 computer, please download the WinSock 2 upgrade facility from the following Microsoft web site: http://www.microsoft.com/windows95/downloads/contents/WUAdminTools/ S_WUNetworkingTools/W95Sockets2/Default.asp Follow the Microsoft installation instructions to upgrade WinSock to Version 2, and then proceed with the DB2 installation. 2.3 Installation instructions Restrictions Once you have installed a FixPak, you cannot uninstall it. Prerequisites Stop all database activity before applying this FixPak. To stop all database activity, issue the commands: db2stop db2admin stop Procedure To install the FixPak, run: X:\SETUP.EXE or run: X:\SETUP.EXE /i where is the language that you want to install. The locale option specified is valid only if that locale exists on the media being used. If the 1.cab file exists in the db2\common\ or db2\windows\common\ directories on the media, then the specified is valid. The valid locale codes are: ENGLISH_UNITEDSTATES "EN" BULGARIAN "BG" CHINESE_TAIWAN "TW" CHINESE_PRC "CN" CZECH "CZ" DANISH "DK" DUTCH "NL" FINNISH "FI" FRENCH_STANDARD "FR" GERMAN "DE" GREEK "GR" HEBREW "IL" HUNGARIAN "HU" ITALIAN "IT" JAPANESE "JP" KOREAN "KR" NORWEGIAN "NO" POLISH "PL" PORTUGUESE_BRAZILIAN "BR" PORTUGUESE_STANDARD "PT" SLOVENIAN "SI" SPANISH "ES" SWEDISH "SE" RUSSIAN "RU" TURKISH "TR" 2.3.1 Applying FixPaks on Windows XP After installing a DB2 version 7.2 FixPak on Windows XP, restart the computer. 2.3.2 Applying FixPaks for Data Links Manager As the DB2 Data Links Manager Administrator (dlmadmin), bring down the DB2 Data Links Manager by stopping the DB2 Data Links Manager service: Select Start and Settings->Control Panel->Services Right click on the DB2 Data Links Manager service and select Stop Ensure that there are no other DB2 processes remaining, by issuing a db2stop command for each instance. Install the FixPak As the DB2 Data Links Manager Administrator, run the following commands to bring up the DB2 Data Links Manager: dlfm bind dlfm start Check the db2diag.log to ensure that the Data Links Manager is started properly. 2.4 Unattended installation instructions The version of SETUP.EXE shipped with this FixPak is capable of running through an unattended installation option. The syntax for this feature is documented in the Quick Beginnings book. A sample response file (DB2FIXPK.RSP) is included in this FixPak. 2.5 After installation 2.5.1 Enabling the new SQL built-in scalar functions FixPak 2 and later of Version 7 delivers new SQL built-in scalar functions. Refer to the SQL Reference and updates in the Release Notes for a description of these new functions. The new functions are not automatically enabled on each database when the database server code is upgraded to FixPak 2 or later of Version 7.1. To enable these new functions, you must login as the instance (or a SYSADM user) and issue the command db2updv7, specifying each database for each instance. This command makes an entry in the database that ensures that database objects created prior to executing this command use existing function signatures that may match the new function signatures. Note: FixPak 8 is the minimum prerequisite if you want to use a Version 8 client to connect to a Version 7 server. Therefore, anyone updating to FixPak 8 will also have to run the db2updv7 command. ATTENTION : If you intend to issue the db2updv7 command, it will change the database so it runs only with Version 7.1 FixPak 2 (or higher) of the database manager. You will not be able to run this database with any previous FixPak level. You must perform a full offline backup of the database prior to running db2updv7 in order to have the ability to restore to a previous FixPak level. 2.5.2 Rebinding bind files Due to the new bind (.bnd) files that have been shipped with this FixPak, you will need to rebind your DB2 utilities against all your databases after the FixPak installation. This step is necessary for the fixes in this FixPak to become effective. The procedure of rebinding, which follows, only needs to be performed once per database. 2.5.2.1 Rebinding to non-DRDA DB2 databases After applying fixes, you must do the following: db2 terminate db2 CONNECT TO db2 BIND $DB2DIR\BND\@db2ubind.lst GRANT PUBLIC db2 BIND $DB2DIR\BND\@db2cli.lst GRANT PUBLIC db2 terminate Where is the name of a database to which the utilities should be bound. DB2UBIND.LST and DB2CLI.LST contain lists of commonly required bind files that are used for DB2. 2.5.2.2 Rebinding to DRDA databases If you are using DB2 Connect to connect to host databases, you will also need to bind the new bind files to the host. As above, use the DB2 Command Line Processor to connect to the host database, and then bind the utilities as follows: HOST COMMAND ===== =================================================================== MVS BIND $DB2DIR\BND\@ddcsmvs.lst BLOCKING ALL SQLERROR CONTINUE GRANT PUBLIC VM BIND $DB2DIR\BND\@ddcsvm.lst BLOCKING ALL SQLERROR CONTINUE GRANT PUBLIC VSE BIND $DB2DIR\BND\@ddcsvse.lst BLOCKING ALL SQLERROR CONTINUE GRANT PUBLIC OS400 BIND $DB2DIR\BND\@ddcs400.lst BLOCKING ALL SQLERROR CONTINUE GRANT PUBLIC 2.5.2.3 Rebinding specific packages If you want to bind only the specific .bnd files to the database, issue the following commands for each database. db2 terminate db2 CONNECT TO db2 BIND $DB2DIR\BND\ BLOCKING ALL GRANT PUBLIC db2 terminate where represents the name of the bind file, and represents the name of your database. 2.5.2.4 Binding db2sch.bnd to existing databases For FixPak installations on the server, an additional bind file needs to be bound to existing databases after applying the FixPak. This requirement does not apply to clients. This additional bind file is db2sch.bnd. Prerequisites If support for DB2 Version 8.1 clients is required, the db2updv7 command must be run following the installation of FixPak 8 or 9. If support for DB2 Version 8.1 clients is not needed, then db2sch.bnd does not need to be bound to existing databases. Procedure To bind db2sch.bnd on the server, execute these commands: At a command prompt: db2 terminate db2 CONNECT TO db2 BIND /db2sch.bnd BLOCKING ALL GRANT PUBLIC sqlerror continue db2 terminate or, At the DB2 command line: TERMINATE CONNECT TO BIND /db2sch.bnd BLOCKING ALL GRANT PUBLIC sqlerror continue TERMINATE where represents the name of a database to which the utilities should be bound, and where represents the full path name of the directory where the bind files are located. 2.5.3 DataJoiner Replication Administration tool The DataJoiner Replication Administration (DJRA) tool (djra.exe) is now installed in the directory $DB2DIR\DJRA. 2.6 Alternate Unicode conversion tables for CCSID 943 Some characters in CCSID 943 have two code points each: "NEC" code point "IBM" code point Some other characters are also represented two code points each: a "NEC" code point and a "JIS" code point. For example, both X'8754' ("NEC") and X'FA4A' ("IBM") refer to the same Roman numeral one character in CCSID 943; and both X'879C' ("NEC") and X'81BE' ("JIS") refer to the same mathematical union symbol in CCSID 943. When using the DB2 default CCSID 943 to Unicode conversion table, both the "NEC" and "IBM"/"JIS" code points are converted to the same Unicode character; but on the reverse, the Unicode character is converted to the "IBM"/"JIS" code point. When using the Microsoft version of the CCSID 943 to Unicode conversion table, both "NEC" and "IBM"/"JIS" code points are also converted to the same Unicode character; but on reverse, the Unicode character is converted to the "NEC"/"JIS" code point. For example: X'8754'or X'FA4A' ==> U+2160 ==> X'FA4A' (using the DB2 default CCSID 943<-->Unicode conversion tables) X'8754'or X'FA4A' ==> U+2160 ==> X'8754'(using the Microsoft version of CCSID 943<-->Unicode conversion tables) X'879C' or X'81BE' ==> U+222A ==> X'81BE' (using either the DB2 default or Microsoft version of CCSID 943<-->Unicode conversion tables) There are also some characters in CCSID 943 that can be converted into two different Unicode characters, depending on whether the DB2 default conversion table or the Microsoft version of the conversion table is used. For example, the double-byte dash character X'815C' in CCSID 943 is converted to the Unicode character U+2014 when using the DB2 default CCSID 943 to Unicode conversion table, but X'815C' is converted to the Unicode character U+2015 instead when using the Microsoft version of the conversion table. If you want DB2 to use the Microsoft version of the conversion tables, follow the procedure below after installation is complete. Prerequisites Before replacing the existing external code page conversion table files in the sqllib/conv directory, you may want to back them up first. On UNIX, sqllib/conv/ is linked to the install path of DB2. Procedure To use the Microsoft version of the CCSID 943 to/from Unicode conversion table files: Copy: sqllib/conv/ms/0943ucs2.cnv to sqllib/conv/0943ucs2.cnv sqllib/conv/ms/ucs20943.cnv to sqllib/conv/ucs20943.cnv sqllib/conv/ms/0941ucs2.cnv to sqllib/conv/0941ucs2.cnv sqllib/conv/ms/ucs20941.cnv to sqllib/conv/ucs20941.cnv Restart DB2. The use of these Microsoft conversion tables is restricted to closed environment between DB2 943 database and DB2 943 clients using the Microsoft version of the conversion tables. If we have a DB2 943 client using the default DB2 conversion tables, and another DB2 943 client using the Microsoft version of the conversion tables, and both clients are connected to the same DB2 943 database, then the same character may be stored as two different code points in the DB2 943 database. 2.7 Uninstallation notes When upgrading or uninstalling the DB2 product(s) on a Windows NT system, it is recommended that you manually shut down all DB2 services and processes on your computer. Note: Once you have installed the FixPak, you cannot uninstall it. 2.8 Known problems and workarounds 2.8.1 Restriction on the db2look command You cannot use the "-f" option of the db2look command from a DB2 Version 7. 2 client at any Version 7 FixPak level. This restriction has been removed in DB2 Version 8. 2.8.2 Additional command modifiers Modifiers have been added to the EXPORT, IMPORT, and LOAD commands. The EXPORT command has the additional modifiers: Table 1. Additional File Type Modifiers (Export) Modifier Description striplzeros Removes the leading zeros from all exported decimal columns. db2 create table decimalTable ( c1 decimal( 31, 2 )) db2 insert into decimalTable values ( 1.1 ) db2 export to data of del select * from decimalTable Content of Exported file data +00000000000000000000000000001.10 db2 export to data of del modified by STRIPLZEROS select * from decimalTable Content of Exported file data +1.10 The IMPORT command has the following additional modifiers: Table 2. Additional File Type Modifiers (Import) Modifier Description timestampformat="x" x is the format of the time stamp in the source file.4 Valid time stamp elements are: YYYY - Year (four digits ranging from 0000 - 9999) M - Month (one or two digits ranging from 1 - 12) MM - Month (two digits ranging from 01 - 12; mutually exclusive with M and MMM) D - Day (one or two digits ranging from 1 - 31) DD - Day (two digits ranging from 01 - 31; mutually exclusive with D) DDD - Day of the year (three digits ranging from 001 - 366; mutually exclusive with other day or month elements) H - Hour (one or two digits ranging from 0 - 12 for a 12 hour system, and 0 - 24 for a 24 hour system) HH - Hour (two digits ranging from 0 - 12 for a 12 hour system, and 0 - 24 for a 24 hour system; mutually exclusive with H) M - Minute (one or two digits ranging from 0 - 59) MM - Minute (two digits ranging from 0 - 59; mutually exclusive with M, minute) S - Second (one or two digits ranging from 0 - 59) SS - Second (two digits ranging from 0 - 59; mutually exclusive with S) SSSSS - Second of the day after midnight (5 digits ranging from 00000 - 86399; mutually exclusive with other time elements) UUUUUU - Microsecond (6 digits ranging from 000000 - 999999; mutually exclusive with all other microsecond elements) UUUUU - Microsecond (5 digits ranging from 00000 - 99999, maps to range from 000000 - 999990; mutually exclusive with all other microseond elements) UUUU - Microsecond (4 digits ranging from 0000 - 9999, maps to range from 000000 - 999900; mutually exclusive with all other microseond elements) UUU - Microsecond (3 digits ranging from 000 - 999, maps to range from 000000 - 999000; mutually exclusive with all other Microseond elements) UU - Microsecond (2 digits ranging from 00 - 99, maps to range from 000000 - 990000; mutually exclusive with all other microseond elements) U - Microsecond (1 digits ranging from 0 - 9, maps to range from 000000 - 900000; mutually exclusive with all other Microseond elements) TT - Meridian indicator (AM or PM) A default value of 1 is assigned for unspecified YYYY, M, MM, D, DD, or DDD elements. A default value of 0 is assigned for all other unspecified elements. Following is an example of a time stamp format: "YYYY/MM/DD HH:MM:SS.UUUUUU" The following example illustrates how to import data containing user-defined date and time formats into a table called 'schedule': db2 import from delfile2 of del modified by timestampformat="yyyy.mm.dd hh:mm tt" insert into schedule The LOAD command has the following additional modifiers: Table 3. Additional File Type Modifiers (Load) Modifier Description timestampformat="x" x is the format of the time stamp in the source file.4 Valid time stamp elements are: YYYY - Year (four digits ranging from 0000 - 9999) M - Month (one or two digits ranging from 1 - 12) MM - Month (two digits ranging from 01 - 12; mutually exclusive with M and MMM) D - Day (one or two digits ranging from 1 - 31) DD - Day (two digits ranging from 01 - 31; mutually exclusive with D) DDD - Day of the year (three digits ranging from 001 - 366; mutually exclusive with other day or month elements) H - Hour (one or two digits ranging from 0 - 12 for a 12 hour system, and 0 - 24 for a 24 hour system) HH - Hour (two digits ranging from 0 - 12 for a 12 hour system, and 0 - 24 for a 24 hour system; mutually exclusive with H) M - Minute (one or two digits ranging from 0 - 59) MM - Minute (two digits ranging from 0 - 59; mutually exclusive with M, minute) S - Second (one or two digits ranging from 0 - 59) SS - Second (two digits ranging from 0 - 59; mutually exclusive with S) SSSSS - Second of the day after midnight (5 digits ranging from 00000 - 86399; mutually exclusive with other time elements) UUUUUU - Microsecond (6 digits ranging from 000000 - 999999; mutually exclusive with all other microsecond elements) UUUUU - Microsecond (5 digits ranging from 00000 - 99999, maps to range from 000000 - 999990; mutually exclusive with all other microseond elements) UUUU - Microsecond (4 digits ranging from 0000 - 9999, maps to range from 000000 - 999900; mutually exclusive with all other microseond elements) UUU - Microsecond (3 digits ranging from 000 - 999, maps to range from 000000 - 999000; mutually exclusive with all other Microseond elements) UU - Microsecond (2 digits ranging from 00 - 99, maps to range from 000000 - 990000; mutually exclusive with all other microseond elements) U - Microsecond (1 digits ranging from 0 - 9, maps to range from 000000 - 900000; mutually exclusive with all other Microseond elements) TT - Meridian indicator (AM or PM) A default value of 1 is assigned for unspecified YYYY, M, MM, D, DD, or DDD elements. A default value of 0 is assigned for all other unspecified elements. Following is an example of a time stamp format: "YYYY/MM/DD HH:MM:SS.UUUUUU" The following example illustrates how to import data containing user-defined date and time formats into a table called 'schedule': db2 import from delfile2 of del modified by timestampformat="yyyy.mm.dd hh:mm tt" insert into schedule 2.8.3 Using APPC listener If you have APPC listener started for your DB2 instance, stop your DB2 instance before stopping your APPC/SNA software. 2.8.4 Correction to Performance Variable Starting in the Release Notes for Version 7 FixPak 6 (and in FixPaks 7 and 8), there is an error in a performance variable name. In "Chapter 13. Configuring DB2" the section "DB2 Registry and Environment Variables" lists Table 5 Performance Variables. In this table a registry variable name is incorrect. The correction is: the variable name DB2_MINIMIZE_LIST_PREFETCH should be DB2_MINIMIZE_LISTPREFETCH. This correction affects FixPak 6, 7, and 8. 2.8.5 Informix Federated support for DB2 Information Integrator The Informix Federated support for DB2 Information Integrator was added starting in DB2 UDB Version 7 FixPak 4. If you have problems installing and configuring it (that is, informix script or related libraries are not installed), you should call the DB2 Support Team for help. 2.8.6 Data corruption after moving from DB2 Version 7 FixPak 8 or earlier to a later Version 7 FixPak or to DB2 Version 8 If you are using JDBC and JTA to connect to a Unicode database, you may experience corruption for in your CHAR, VARCHAR, and CLOB data after you migrate to DB2 UDB Version 7 FixPak 9, or to DB2 UDB Version 8. The corruption only affects data with a hexadecimal value between 80 and FF. Characters in the normal ASCII range are not affected. For more information, refer to the "Data corruption after moving from DB2 Version 7 FixPak 8 or earlier to a later Version 7 FixPak or to DB2 Version 8" technote. 2.8.7 Exploiting Large Memories - Update A clarification of how to use the Microsoft Address Windowing Extensions (AWE) has been recorded in a Frequently asked question (FAQ) called "Exploiting Large Memories - Update" on the DB2 Universal Database Support web site. Clarification has been asked for regarding the independence of the two Windows boot options /3GB and /PAE, and Microsoft Address Windowing Extensions (AWE). The boot option /3GB has to do with creating a different address space partition. The boot option /PAE has to do with accessing memory beyond 4 GB using AWE. If you do not use AWE, you cannot access that part of the memory. AWE does not necessarily have to address memory beyond 4 GB and so AWE can be used without /PAE. When using the DB2_AWE registry variable, do not confuse the DB2 UDB pages with physical pages in Windows. Recall that DB2 UDB page sizes can be one of 4 KB, 8 KB, 16 KB, or 32 KB. The number of pages referred to in DB2_AWE will be one of the DB2 UDB page sizes. For more information, refer to the Frequently asked question (FAQ) called "Exploiting Large Memories - Update" on the DB2 Universal Database Support web site. 2.8.8 Application Development and supported software update For application development and supported software updates, visit the DB2 application development Web site at: http://www.ibm.com/software/data/db2/udb/ad/v7 2.8.9 Informix Federated support for DB2 Relational Connect Informix Federated support for DB2 Relational Connect was added in DB2 FixPak 4. If you have problems during installation or configuration (informix script and/or related libraries not installed with FixPak 4), you should call DB2 Support Team for help. 2.8.10 Loss of Control Center functionality There should be no problems introduced against back-level Control Center clients by applying FixPak 2 or FixPak 3 to a DB2 server. However, in DB2 Version 7.2, back-level Control Center clients will lose nearly all functionality. Back-level in this case refers to any Version 6 client prior to FixPak 6, and any Version 7 client prior to FixPak 2. Version 5 clients are not affected. The suggested fix is to upgrade any affected clients. Version 6 clients must be upgraded to FixPak 6 or later, and Version 7 clients must be upgraded to FixPak 2 or later. 2.8.11 Using DB2 XML Extender The readme.nt file lists Software Requirements of DB2 Universal Database Version 6.1 or higher with FixPak 3 installed. This is incorrect. The DB2 XML Extender requires DB2 Version 7.1 or 7.2. 2.8.12 Restoring backup images created under FixPak 4 or greater When the RELOCATE USING option is used with the db2inidb command, the user provided configuration file is copied into the database directory (for example, SQL00001) and is renamed db2path.cfg. If the database was initialized as a snapshot, then the db2path.cfg file is removed after the necessary crash recovery completes. However, if the database was initialized as a standby, then the file will only be removed after the database is taken out of the rollforward pending or in-progress state (by stopping or cancelling the rollforward). Standby databases that do not contain SMS table spaces can be backed up when in the rollforward pending or in-progress state. If the db2path.cfg file exists for such a database, then it will be included in the backup image. Because this file is new to V7 beginning with FixPak 4, a restoration of an image containing this file will fail on any V7 level earlier than FixPak 4. If restoring from such a backup image, the instance must be running with a DB2 level of FixPak 4 or greater. 2.8.13 Updates into local tables in federated systems You can perform insert, update, and delete operations into local tables in an MPP federated environment. Although a workaround for INSERT statements was provided in FixPak 4, the workaround is no longer needed. This capability is fully enabled in FixPak 9. 2.9 Version 7 FixPak 10a Updates 2.9.1 Longer than normal database activations or first connects If you have recoverable logging configured (LOGRETAIN=ON or USEREXIT=ON) and more than 4 GB of log space configured ( (LOGPRIMARY+LOGSECOND) * LOGFILSIZ * 4K ), you may experience longer than normal database activations or first connects. If the database is consistent at the time of activation, DB2 will unnecessarily reallocate log files, which is the reason for slow activation. This behavior may lead to rollforward or crash recovery failures. If these reallocated log files are used during a rollforward, the rollforward will fail with SQL1265 - archive log file is not associated with the current log sequence. A previous log file reallocation may result in the recreated log file not chained correctly with the previous log file. Rollforward fails when trying to process this log file. Crash recovery may fail when running a very large transaction requiring log space that spans across greater than 4 GB of active log space. This causes a wrong log sequence number to be written to the transaction logs on disk, which will cause DB2 crash recovery to fail. 2.9.2 Search Discovery Listener Denial of Service Vulnerability A vulnerability exists in the DB2 "Discovery" service that allows a skilled remote user to cause the Discovery service to stop responding by sending a malicious network packet. This creates a denial of service situation for the Discovery service only. If search discovery was being relied on to find DB2 servers on a local subnet, these would not be found after the listener was disabled. The only interim workaround is to preemptively disable discovery services. 2.9.3 db2job security exposure An exposure exists in the db2job and db2job2 programs that could allow a skilled user with local login access to a UNIX system where DB2 is installed to obtain system administrator ("root") privileges. An interim workaround exists and involves disabling job scheduling.
