# Changes in the 2.7 release

## Rename module to DB2::Admin

The modules/classes have been renamed from DB2API to DB2::Admin as recommended by Tim Bunce.

## Add "list of files" support for Load of DEL files

The Load method now supports loading a list of DEL files in a single command.

## Support new protocol, types for node directory

Support the TCP/IP v4, TCP/IP v6 and TCP/IP v4 using SOCKS protocol types for the node directory methods.

# Changes in the 2.6 release

## Add XML support to Export, Import and Load methods

The Export, Import and Load methods now supports the XML options introduced in DB2 V9.1 (Export, Import) and DB2 V9.5 (Load). Note that the schema-related XML validate / default / ignore / map options are not supported at this time.

## Add connect attributes

Allow the user to specify the program name and connect time-out as connect attributes. Default options can be set with `SetConnectAttributes` and per-connect options can be specified with the `ConnectAttr` parameter to the `Connect` method.

The default program name is no longer `perl` or `perl5.8`, but the script name (the basename of `$0`).

# Changes in the 2.5 release

## Add the NoCharDel option for the import and load commands

The NoCharDel option, which is used to handle files where character strings have no delimiters, is now supported for FileOptions parameters of the the Import and Load methods. It was already supported for the Import method.

## Support "Update Profile Only" for Runstats

The implementation of the runstats API contained a bug that made ``update profile only'' not work. This was due to an discrepancy between the documented constant name in the IBM documentation (DB2RUNSTATS_UPDATE_PROFILE_ONLY) and the actual #define (DB2RUNSTATS_UPDA_PROFILE_ONLY), missing the letters TE from the middle.

The code now handles both cases

## Fine-tune error handling

The error handling now differentiates between errors and warnings. The default behavior is unchanged - error messages are printed for errors and warnings, and no exception is thrown. However, the 'RaiseError' option now only throws exceptions for errors, not warnings - the new 'RaiseWarn' option handles the latter.

## Support the ExcludingXML option for the Runstats command

The new DB2RUNSTATS_EXCLUDING_XML flag for the db2Runstats API is now supported as the ExcludingXML option.

## Support the CodePage file type modifier

The Export, Import, and Load commands now support the CodePage file type modifier. The Load command claimed to support this before,. but the implementation was incorrect.

## Rename the system admin group constants

The SysAdm, SysMaint, SysCtrl and SysMon group instance configuration parameters (SQLF_KTN_xxx_GROUP) were limited to 16 characters in DB2 V8.1 and before. With DB2 V8.2, new configuration parameters were introduced that changed this limit to 30, but had a different name: SQLF_KTN_xxx_GRP. However, the documentation hides this difference and refers to the new parameters by the old name.

DB2 V9.1 introduces a bug in the handling of the old parameters. In order to work around this, the new parameters now override the old ones in the parse_constants script. So in DB2 V8.2 and above, the old names (e.g. 'sysadm_group') can be used and do the right thing by using the new constants.

# Changes in the 2.4 release

## Changes in db2CfgGet / db2CfgSet for V9.1

The get/update instance/database configuration parameters methods have new flags for DB2 V9.1: 'Computed' (get/set) and 'Manual' (set). Add support for these new flags.

The only value that supports 'Computed' as far as I am aware, is 'database_memory'. When the Command Line Processor reports it as 'computed', the admin API can now do the same.

The 'Manual' option allow you to turn off automatic management for parameters while DB2 maintains the last automatically set value.

## Support for new format IP v4 for datastream elements

When IP v4 clients running DB2 V9.1 connect to a database, the application id has a new format and includes the IP address and port in plain text. Support this new format and straighten out the existing IP v4 format so it is now always ``<address> port <port>''.

# Changes in the 2.3 release

## Changes in db2Load API for V9.1

On DB2 V9.1, use the ``iSetIntegrityPending'' field for the db2Load API instead of the ``iCheckPending'' field.

## IP v6 support for datastream elements

Support IP v6 addresses for the application-id in snapshot and event monitor data elements (untested)

## Add new instance and database configuration parameters for V9.1

The following database manager and database configuration parameters are new for DB2 V9.1 and have been added:

federated_async
fcm_num_channels
self_tuning_mem
db_mem_thresh
db_collname
restrict_access

# Changes in the 2.2 release

## Add basic support for DB2 V9.1

The module now compiles on DB2 V9.1. No new features are supported, but the makefiles and various utility scripts have been adjusted and compile issues fixed.

No support has been added for new instance / database configuration parameters or for the new XML-related features of db2Import and db2Export.

## Add ClientInfo method

A new ClientInfo method can be used to get/set the TPM client information (sqleseti, sqleqryi).

# Changes in the 2.1 release

## Add DPF options to the Load command

Various DPF-related options for the Load command are now supported. In addition, a more detailed second return value describes the DPF aspects of the load, including each agent, in detail.

# Changes in the 2.0 release

## Add LOB support to the Export, Import and Load methods

Support for the LobPath, LobFile and LobsInFile options of the Export, Import and Load methods has been added. (LobFile is Export specific.)

## Add the 'DelPriorityChar' option

Support for the 'DelPriorityChar' option for the DEL file type modifiers of Import/Load now supports data files with embedded newlines in column values.

## Support the DB2 V8.2 FP9 enhanced deadlock event monitor

The enhanced deadlock event monitor in DB2 V8.2.2 (FP9) writes a new type of monitoring element, called 'handle' (but really a blob).

Support to decode this has been added (the data is returned as a hexadecimal string).

# Changes in the 1.9 release

## Fix bugs in Load option handling

The XS code was handling load options incorrectly, leading the 'NonRecoverable' flag to set the ``HoldQuiesce'' flag instead, and leading the ``Allow Read Access'' flag to set the IndexingMode to ``rebuild''.

## Support the SQLM_HEAP_xx constants

The various constants for database manager, database and application pool ids are now supported. Previously, a numeric code was displayed.

# Changes in the 1.8 release

## Support fork()ing programs

The XS code now detects a `fork()` has occurred and will mark as closed database connections opened by the parent. This requires some care, as closing the connection in the child will affect the connections in the parent. And, of course, IBM doesn't properly document this.

## Handle cross-partition connection names

The code parsing connection names got cross-DPF node connections wrong and spewed out large amounts of ``unitialized value'' warnings. Now corrected.

# Changes in the 1.7 release

## Support the ReorgStatus constants

The reorg status constants returned by database snapshots are now supported. Previously, a numeric code was displayed.

## Support the HADR constants

The HADR-related constants returned by database snapshots (HADR role, state, syncmode, connection status) are now supported. Previously, a numeric code was displayed.

# Changes in the 1.6 release

## Bugfix for Runstats method

Bugfix for the 'Runstats' method: you can now collect index statistics using a previously set profile without collecting/updating column statistics.

## Bugfix for Runstats, Rebind methods

Bugfix for the 'Runstats' and 'Rebind' methods: the low-level administrative API functions used to implement these methods ignore the connection-level auto-commit flag. This means they will continue to hold locks on the catalog until an explicit commit or disconnect is issued.

Both methods now explicitly issue a commit (whether the low-level call succeeded or not).

## Support 'TempFilesPath' for Load method

A new 'TempFilesPath' parameter for the Load method allows users to specify the pathname for load temporary files.

# Changes in the 1.5 release

## Add Runstats method

A new 'Runstats' method can be used to collect table and index statistics. Only a subset of options is supported; specifically, the column distribution options and column group features are not supported. This may change in future releases. This method requires DB2 V8.

## Minor Load FileOptions changes

Minor changes to the 'FileOptions' parameter to the 'Load' method: fix some typos, add 'DumpFileAccessAll', add documentation.

## Bugfix for "load terminate"

The perl and XS code for 'LOAD' got the caller_action wrong; this was set to SQLU_TERMINATE for a ``LOAD TERMINATE'', but should always be set to SQLU_INITIAL. This removes code and is a Good Thing...

## Add ListUtilities method

A new 'ListUtilities' method supports listing currently active utilities. It is implemented using an instance snapshot and requires DB2 V8.

# Changes in the 1.4 release

## Support exception tables for Load

The Load method now supports the optional 'ExceptionTabe' and 'ExceptionSchema' parameters to set the exception table for load exceptions.

## Support the 'Utility type' constants

The 'utility type' constants returned by instance snapshots are now supported. Previously, a numeric code was displayed.

# Changes in the 1.3 release

## Add more Export options

Add the 'StripZeros', 'DatesISO' and 'DecPlusBlank' options to the Export file modifiers

## Handle quoting for FileOptions

FileOptions for Import, Export and Load that contain embedded blanks (e.g. a TimestampFormat like 'MMM D YYY H:M:S') are now quoted before being fed to the DB2 APIs.

## Add LoadQuery method

A new LoadQuery method allows you to query the progress of a Load command against a table.

# Changes in the 1.2 release

## Add ListHistory command

A new ListHistory method implements the equivalent of the CLP ``List History'' command that allows you to query loads, backups, rollforwards, etc.

## Make test suite configurable

A CONFIG file is used to drive the test suite, externalizing the names of the test database, test tables, schema names, etc.

# Changes in the 1.1 release

## Add Load method

New Load method provides an API to the table load functions; only a subset of features is supported (most notably, partitioned loads, table hierarchies, TSM media, LOBs and Data Links are not supported).

## Add TargetColumns, InputColumns to Import method

New parameters to the Import method allow specification of the target columns and selection of the relevant columns from the input file (by position or DEL files and by name for IXF files).

## Add ImportOptions to Import method

Add import options to the 'Import' method; this allows users to set commit count, warning count, row count, skip count, etc. Most options are available only with DB2 V8.2.

# Changes in the 1.0 release

## Add CatalogDatabase / UncatalogDatabase methods

New methods to catalog a database in the database directory or uncatalog one.

## Add CatalogNode / UncatalogNode methods

New methods to catalog a node in the node directory or uncatalog one.

## Add CatalogDCSDatabase / UncatalogDCSDatabase methods

New methods to catalog a DCS database in the DCS directory or uncatalog one.

## Add import/export options for DEL files

The following import options have been added for DEL files: `DateFormat`, `TimeFormat`, `TimestampFormat`, `ImpliedDecimal`, `StripTBlanks`.

The following export options have been added for DEL files: `NoCharDel`, `TimestampFormat`.

## Use db2Export/db2Import function for export/import

On DB2 V8.2, the new db2Export function is used instead of sqluexpr and the new db2Import function is used instead of sqluimpr.

## Use db2DbDirXXX functions for GetDatabaseDirectory()

The `DatabaseDirectory()` method now uses the db2DbDirXXX functions when available (DB2 V8.2). For global database directories, this means the new 'Alternate Hostname' and 'Alternate Port Number' fields are returned for HADR setups.

# Changes in the 0.9 release

## Add import/export functions

Building on the database connection functions, provide limited table export/import methods.

## Add database connection functions

New Connect and Disconnect functions allow database connections; this is implies the database configuration get/set functions can now use the 'Immediate' option.

# Changes in the 0.8 release

## Add more database manager configuration parameters

All medium/high important updatable database manager configuration parameters have been added.

# Changes in the 0.7 release

## More value types formatted by DB2API::DataElement

More types of monitor elements are being formatted by the DB2API::DataElement class. This includes lock mode, statement type/operation, server platform, application status.

## DB2API::EventParser more tolerant of unexpected files

The EventParser class warns when it encounters un-expected files. It now does not warn for hidden files (dotfiles) that we use internally to keep track of event file state.

# Changes in the 0.6 release

## Linux/ia64 (Itanium) support

Make the module work on Linux/ia64 (Itanium) and DB2 V8.2.0

## DB2 V8.2 support on Solaris

Make the module work on Solaris 7/8 with DB2 V8.2.0 (32-bit perl only)

# Changes in the 0.5 release

## Accept unknown elements in DB2API::DataStream, DB2API::DataElement

When an unknown monitoring element / even code is found, the decoding functions now return ``(unknown element XXX)'' instead of `die()ing.`

## Convert tests to Test::More

All tests have been converted to the Test::More framework

## Add ForceApplications and ForceAllApplications methods

Two new methods can be used to force selected applications or all applications. These should obviously be used with care.

## Add GetDCSDirectory method

A new method allows retrieval of the DCS (gateway) directory

## Change keys in catalog entries

The name of the keys in the `GetDatabaseDirectory()` and `GetNodeDirectory()` methods has been changed to match the (Morgan Stanley private) reverse-engineered catalog decoding/generation code.

## Support for event files

Add an event file parser module, `DB2API::EventParser` which can 'tail' growing event files and delete those marked as processed. A sample program provides the skeleton for a minimal event monitor.

## More configuration parameter work

The checking script now warns if IBM-internal configuration parameters are used; more V8.2 configuration parameters have been added.

# Changes in the 0.4 release

## Add additional configuration parameters

A number of additional database and database manager configuration parameters have been added; this includes support for a 'float' type, constants used for both the database and the database manager, and a mechanism to try and deal with configuration parameter names that have switched to a new constant name and new type between releases.

## Add additional constant categories

Add the 'LockMode' and 'LockObjectType' categories to the `DB2API::Constants` `Lookup` method; use these in the `DB2API::DataElement` `getValue` method.

# Changes in the 0.3 release

## Re-implement self-describing data stream class

The `DB2API::Elements` class has been replaced by `DB2API::DataStream` and `DB2API::DataElement`, which decode the information lazily and provide an object-oriented interface to get the data, including a path search loosely modeled after XPath.

## Add GetDatabaseDirectory and GetNodeDirectory methods to DB2API

These new methods allow retrieval of the database directory and node directory.

## Database/Dbm Config methods support multiple flags

The database / database manager config methods now support passing in a single 'Flag' parameter string, or a reference to a hash with multiple flags.

## Bugfixes and V7 inter-operability fixes

Basically, release 0.2 did not work very well in practice (dealing with 64-bit values, very slow decoding of snapshot data). A number of small fixes were applied to DB2API::Elements to address this.

# Changes in the 0.2 release

## Add UpdateDatabaseConfig method to DB2API

This new method allows updating of database configuration parameters. Until such time that we support database connections, only delayed database parameters updates are allowed.

## Add GetDatabaseConfig method to DB2API

This new method allows retrieval of database configuration parameters. Until such time that we support database connections, only delayed and default database parameters may be retrieved.

## Add UpdateDbmConfig method to DB2API

This new method allows updating of database manager configuration parameters.

## Add GetDbmConfig method to DB2API

This new method allows retrieval of database manager configuration parameters.

## Add GetConfigParam method to DB2API::Constants

This new method allows lookup of meta-data about configuration parameters. The API is provisional, as I have not yet decided how to deal with parameters that change constant name and type between DB2 releases.

## Add to DB2API::Constants

The constants generated are now for both `sqlmon.h` and `sqlutil.h`
