Db2move import

When used in the COPY mode, this tool facilitates the duplication of a schema. The tool queries the system catalog tables for a particular database and compiles a list of all user tables. Tables with structured type columns are not moved when this tool is used. This tool calls the DB2 export, import, and load APIs, depending on the action requested by the user.

Therefore, the requesting user ID must have the correct authorization required by those APIs, or the request will fail. If specified, only those tables created by the definers listed with this option are exported. If not specified, the default is to use all definers. When specifying multiple definers, they must be separated by commas; no blanks are allowed between definer IDs. This option can be used with the -tn table-names option to select the tables for export.

If not specified, the default is to use all user tables. When specifying multiple table names, they must be separated by commas; no blanks are allowed between table names.

Table names should be listed unqualified and the -sn option should be used to filter schemas. The table names should be listed with their schema qualifier in the format "schema". If specified, only those tables whose schema names match will be exported or copied. If multiple schema names are specified, they must be separated by commas; no blanks are allowed between schema names. Schema names of less than 8 characters are padded to 8 characters in length.

If not specified, the default is to use all schemas. If used with the -tn or -tc option, db2move will only act on those tables whose schemas match the specified schema names and whose definers match the specified definers.

If this option is specified, only those tables that reside in the specified table space will be exported. If the -ts option is not specified, the default is to use all table spaces.

If multiple table space names are specified, they must be separated by commas; no blanks are allowed between table space names. Table space names less than 8 characters are padded to 8 characters in length. Running multiple db2move commands to copy schemas from one database to another will result in deadlocks. Only one db2move command should be issued at a time. Changes to tables in the source schema during copy processing may mean that the data in the target schema is not identical following a copy.

This is an optional option that is only used with the COPY action.The tool queries the system catalog tables for a particular database and compiles a list of all user tables. Tables with structured type columns are not moved when this tool is used. This tool calls the DB2 export, import, and load APIs, depending on the action requested by the user. Therefore, the requesting user ID must have the authorization that the APIs require, or the request fails.

If you specify the -tc parameter, only those tables that were created by the specified definers are exported. If you do not specify this parameter, all definers are used. If you specify multiple definers, you must separate them with commas; no blanks are allowed between definer IDs. If you specify the -tn parameter with the EXPORT action, only those tables whose names match those in the specified string are exported. If you do not specify this parameter, all user tables are used.

If you specify multiple table names, you must separate them with commas; no blanks are allowed between table names. Table names must be listed unqualified.

To filter schemas, you should use the -sn parameter. The table names must be listed with their schema qualifiers in the format " schema ".

If you specify multiple schema names, you must separate them with commas; no blanks are allowed between schema names. Schema names of fewer than 8 characters are padded to 8 characters in length. If you use the -sn parameter with the -tn or -tc parameter, the db2move command acts on only those tables whose schemas match the specified schema names or whose definers match the specified definers.

If you specify the -ts parameter, only those tables in the specified table space are exported. If you do not specify the -ts parameter, all table spaces are used. If you specify multiple table space names, you must separate them with commas; no blanks are allowed between table space names.

Table space names with fewer than 8 characters are padded to 8 characters in length. In the file, you should list the table names with their schema qualifier in the format " schema ".

Running multiple db2move commands to copy schemas from one database to another will result in deadlocks. Only one db2move command should be issued at a time. Changes to tables in the source schema during copy processing may mean that the data in the target schema is not identical following a copy.In a previous article Cloning DB2 Databases Using Redirected RestoreI described a step-by-step procedure for cloning a database residing on one system to another machine or instance running on the same platform.

The idea is to perform a redirected restore operation on a full database backup image. But what if the source and target platforms are not the same?

In this case, a redirected restore operation won't do the trick, because you can't usually back up a database on one operating system, and restore it on another operating system. The db2move utility exploits the DB2 data movement utilities export and import or load to move the database tables. However, because a database is so much more than user tables, you need some way to transfer other database objects, such as constraints, triggers, indexes, sequences, table spaces, buffer pools, among others.

That's where the db2look utility comes in. Using this tool, you can capture the data definition language DDL for such objects in the source database, and apply it to recreate those objects in the target database. The db2move utility retrieves a list of all user tables in a database from the system catalog.

Files that db2move generates during an export operation are used as input files for the ensuing import or load operation see Table 1. If a db2move operation is to succeed, the requesting user ID must have the correct authorization required by the underlying DB2 data movement utilities. A database connection is not required prior to invoking the db2move command; the utility does that for you. You must specify the name of the database whose tables you want to move, and the action export, import, or load that is to be performed.

You can then specify an option to define the scope of the operation. For example, you can limit the operation to certain tables -tntable spaces -tstable creators -tcor schema names -sn. Specifying a subset of tables, table spaces, or table creators is valid with the export action only. If multiple values are specified, they must be separated by commas; no blanks are allowed between items in the list of values.

How to use db2move

The maximum number of items that can be specified is Alternatively, you can specify the -tf option with the name of a file that lists the tables to export. The fully qualified table names should be listed one per line. You can also specify:. Table 1. Files that are required or generated during export, import, and load operations managed by the db2move utility. The file name extension is a number ranging from toand a is an alphabetic character. The db2look utility extracts the DDL statements that are required to reproduce database objects on a different system.

A database connection is not required prior to invoking the db2look command; the utility does that for you. You must specify the name of the database whose objects you want to describe. You can then specify one or more options in any order to define the scope of the extraction, including:. Let's work through an actual example. Write the output to a file called db2look.

Step 3: On Windows, ftp to the AIX system and retrieve the required input files for the final db2move operation. The subsequent insert operation fails, however, because the year value violates the check constraint.

A valid value is successfully inserted. We have seen how two DB2 utilities, db2move and db2lookcan be used to facilitate database cloning in situations where there is no support for cross-platform backup and restore operations. You can easily adapt the example that is described in this article to clone DB2 databases in your environment.

The DDLs genereated using db2look creates constraints while restoring the database and hence the data error happens during importing data using db2move. Its better to execute the table defenition and fk constraint defenition in different process. After you run the db2look to dump the ddl of your database.

Just separate the foreign key constraint to the separate file. Better be if the other object like triggers, sp, or views on different file too. So, right after you load the data, execute the fk constarint, triggers, sp, and views. Learn more. Asked 7 years, 7 months ago. Active 7 years, 2 months ago. Viewed 4k times. Active Oldest Votes.

The table names should be listed with their schema qualifier in the format "schema". If specified, only those tables whose schema names match will be exported or copied.

If multiple schema names are specified, they must be separated by commas; no blanks are allowed between schema names. Schema names of less than 8 characters are padded to 8 characters in length. If not specified, the default is to use all schemas.

If used with the -tn or -tc option, db2move will only act on those tables whose schemas match the specified schema names and whose definers match the specified definers. If this option is specified, only those tables that reside in the specified table space will be exported. If the -ts option is not specified, the default is to use all table spaces.

If multiple table space names are specified, they must be separated by commas; no blanks are allowed between table space names. Table space names less than 8 characters are padded to 8 characters in length. Running multiple db2move commands to copy schemas from one database to another will result in deadlocks.

Only one db2move command should be issued at a time. Changes to tables in the source schema during copy processing may mean that the data in the target schema is not identical following a copy.

Maintaining the same schema name as the source will avoid these issues. If there are cross dependencies between schemas, all inter-dependant schemas must be copied or there may be errors copying the objects with the cross dependencies. If a target schema already exists, the utility will fail.Could anyone point me to any URL or manuals where I can get clear difference between the db2move and db2 exports and imports? The difference in terms of restrictions I am looking at.

I have a need of getting all the data from one database to another database and with replace. Almost all the tables are not big and in a range of 1 to 2m. Only few tables are with 26m records. My idea was to go for export and import and then do load for the bigger tables. But my colleague says when we are doing all the tables then go for db2move with export and import mode. Any pointers for good bench mark as well restrictions.

I don't recall that changing too much in9. Db2move is kind of a brute force method - I keep hoping they'll improve it. If you're doing lots of sophisticated options db2move probably won't work for you. Modified by options. That's the major difference I've noticed. Thank you very much. In the first case, it will export tables in alphameric order.

Using DB2 utilities to clone databases across different platforms

When you go to load or import tables, it will do that in the same sequence. This has significant impact if you have referential integrity defined and use import.

db2move import

You can mitigate the impact by reordering the records in the db2move. If the two databases are of the same version and the target database server has the source database cataloged, you can use the COPY command of db2move to copy the tables directly from one database to the other without building the intermediate export files.

Finally, and most importantly, I would totally discard using import. It is significantly slower than load It logs every insert meaning you will burn through the transaction logs and I do not believe db2move will perform intermediate commits, which means you risk import failures due to log full conditions The indexes will be built during inserts instead of at load completion, potentially resulting in wasted space and unbalanced indexes The tables MUST be imported in specific order if referential integrity is involved, requiring more setup work, versus performing set integrity after the loads.

Db2move with the COPY option does allow load of a table with identity columns. DB2 will give a warning that he is overriding the generation. We can reset the counter of autogenerate column once we done load, using alter table statement. Export, Import, and Load do a single table at a time only.

Might take a bit of time to script. If you don't need anything fancy like 'modified by' options, then db2move is the easier way to go for a large of tables.

One deciding factor can also be whether you need to create the tables on the target database. If you do then you either need to incorporate db2look or use the import method of db2move or import and not load.

Run db2look with -e -a and maybe -x on the source database 2. Manually split the db2look output file right before the Foreign Keys 3.Objective: use db2 control center to create another testing database and tablespace, then use db2look and db2move to export then import the production database data into this testing database.

Database name is DB1, the os and schema user name is user1 Steps: 1. Install same version of IBM db2 database on testing server note: Setup database runtime client side parameters, such as db2 node directory and db directory db2? Use db2look to generate DDL statements for later use db2look -d db1 -e -z user1 -o user1.

Also take note the schema name and tablespace name might need to be changed also. Preparing table and view granting script cat db2look. Run the first part of db2look You can modify db2move. Search: db2move load import lobsinfile incompatible Problem encountered during using db2move load to load tables Search: db2move load —lo replace ,insert Due to tablespace has no free pages left. Check message file tab After importing data, import the second db2look You can test the connection from client to server from runtime client application server.
