We care about the privacy of our clients and will never share your personal information with any third parties or persons. The value is the number of process to use to parallelize the select query. Default is parallel query disable. This directive is used to defined the number of tables that will be processed in parallel for data extraction.
The limit is the number of cores on your machine. Ora2Pg will open one database connection for each parallel table extraction. A value of 0 or 1 disable the use of parallel hint.
Default is no foreign server defined. For export type FDW the default value is orcl. Use this directive to precise which transformation should be applied to a column when exporting data. Value must be a semicolon separated list of. If you want to preserve the existing schema because of modifications or the use of a third party server, disable this directive.
To not export these tables at all, set the directive to 0. Internal timestamp retrieves from custom type are extracted in the following format: JAN It is impossible to know the exact century that must be used, so by default any year below 49 will be added to and others to You can use this directive to change the default value Default is to not scan this table and to never look for queries.
Note that queries will be normalized before output unlike when a file is given at input using the -i option or INPUT directive. Default is to use de postgresql. In this case disable this directive and the BLOB columns will not be included into data export. By default data export order will be done by sorting on table name.
If you have huge tables at end of alphabetic order and you are using multiprocess, it can be better to set the sort order on size so that multiple small tables can be processed before the largest tables finish. In this case set this directive to size. Possible values are name and size. You may want to export only a part of an Oracle database, here are a set of configuration directives that will allow you to control what parts of the database should be exported.
This directive allows you to set a list of objects on which the export must be limited, excluding all other objects in the same type of export. The value is a space or comma-separated list of objects name to export. You can include valid regex into the list.
The object depends of the export type. This is the manner to declare global filters that will be used with the current export type. You can also use extended filters that will be applied on specific objects or only on their related export type.
This will exclude partitioned tables for year to from the export but not the main partition table. The trigger will also be adapted to exclude those table. With GRANT export you can use this extended form to exclude some users from the export or limit the export to some others:. But if you don't want to export grants on some functions for these users, for example:. Oracle doesn't allow the use of lookahead expression so you may want to exclude some object that match the ALLOW regexp you have defined.
For example if you want to export all table starting with E but not those starting with EXP it is not possible to do that in a single expression. This is why you can start a regular expression with the! Our previous example can be written as follow:. This directive is the opposite of the previous, it allow you to define a space or comma-separated list of object name to exclude from the export.
Set which view to export as table. By default none. Value must be a list of view name or regexp separated by space or comma. If the object name is a view and the export type is TABLE, the view will be exported as a create table statement. By default Ora2Pg try to order views to avoid error at import time with nested views. With a huge number of views this can take a very long time, you can bypass this ordering by enabling this directive. When exporting GRANTs you can specify a comma separated list of objects for which privilege will be exported.
Default is export for all objects. Only one object type is allowed at a time. You can use the -g option to overwrite it. When used this directive prevent the export of users unless it is set to USER. In this case only users definitions are exported. Both are possible too.
Here are some examples:. Any where clause not included into a table name bracket clause will be applied to all exported table including the tables defined in the where clause. These WHERE clauses are very useful if you want to archive some data or at the opposite only export some recent data.
To be able to quickly test data import it is useful to limit data export to the first thousand tuples of each table. For Oracle define the following clause:. Command line option -W or --where will override this directive for the global part and per table if the table names is the same.
This directive is used to limit the number of item shown in the top N lists like the top list of tables per number of rows and the top list of largest tables in megabytes. By default it is set to 10 items. Enable this directive if you want to continue direct data import on error. Like this you can try to fix the statement and manually reload the error log file.
Default is disabled: abort import on error. Sometime you may want to extract data from an Oracle table but you need a custom query for that. This directive allows you to overwrite the query used by Ora2Pg to extract data. Several directives can be used to control the way Ora2Pg will export the Oracle's Text search indexes. To force Ora2Pg to create an extra tsvector column with a dedicated triggers for FTS indexes, disable this directive.
When the Oracle text index is defined over multiple column, Ora2Pg will use setweight to set a weight in the order of the column declaration. Use this directive to force text search configuration to use.
If you want to perform your text search in an accent insensitive way, enable this directive. In your queries you will need to use the same function in the search to be able to use the function-based index. One of the great usage of Ora2Pg is its flexibility to replicate Oracle database into PostgreSQL database with a different structure or schema.
There's three configuration directives that allow you to map those differences. Enable this directive to reordering columns and minimized the footprint on disc, so that more rows fit on a data page, which is the most important factor for speed.
Default is disabled, that mean the same order than in Oracle tables definition, that's should be enough for most usage. This directive allows you to limit the columns to extract for a given table.
The value consist in a space-separated list of table name with a set of column between parenthesis as follow:. With TABLE export create table DDL will respect the new list of columns and all indexes or foreign key pointing to or from a column removed will not be exported.
This directive allows you to remap a list of Oracle table name to a PostgreSQL table name during export. The value is a list of space-separated values with the following structure:. Like table name, the name of the column can be remapped to a different name using the following syntax:.
If you want to change the type of some Oracle columns into PostgreSQL boolean during the export you can define here a list of tables and column separated by space as follow. You can also give a type and a precision to automatically convert all fields of that type as a boolean. Use this to add additional definition of the possible boolean values used in Oracle fields.
By default here are the values recognized by Ora2Pg:. If you can not remove the constraint, use this directive to set an arbitral date that will be used instead. Add the given value as suffix to indexes names. Useful if you have indexes with same name as tables. Could be very useful for database that have multiple time the same index name or that use the same name than a table, which is not allowed by PostgreSQL Disabled by default.
The difference from the default operator classes is that the values are compared strictly character by character rather than according to the locale-specific collation rules. This makes these operator classes suitable for use by queries involving pattern matching expressions LIKE or POSIX regular expressions when the database does not use the standard "C" locale.
If you enable, with value 1, this will force Ora2Pg to export all indexes defined on varchar2 and char columns using those operators.
If you set it to a value greater than 1 it will only change indexes on columns where the character limit is greater or equal than this value. Enable this directive if you want that your partition table name will be exported using the parent table name.
Disabled by default. If you have multiple partitioned table, when exported to PostgreSQL some partitions could have the same name but different parent tables. This is not allowed, table name must be unique. Enable this directive if you want that your subpartition table name will be exported using the parent partition name. Enabled by default. If the partition names are a part of the subpartition names, you should enable this directive. If you don't want to reproduce the partitioning like in Oracle and want to export all partitioned Oracle data into the main single table in PostgreSQL enable this directive.
Ora2Pg will export all data into the main table name. Default is to use partitioning, Ora2Pg will export data from each partition and import them into the PostgreSQL dedicated partition table. You may want to fully disable this feature because you will lose all data from unlogged tables in case of a PostgreSQL crash. Set it to 1 to export all tables as normal tables. Ora2Pg fully export Spatial object from Oracle database. There's some configuration directives that could be used to control the export.
By default Ora2Pg is looking at indexes to see the spatial constraint type and dimensions defined under Oracle. Those constraints are passed as at index creation using for example:. The directive is enabled by default.
If those two extract type are calls at Oracle side, they are slow and you can easily reach Out Of Memory when you have lot of rows. This is a work in progress, please validate your exported data geometries before use. Tuples are stored in memory before being written to disk, so if you want speed and have enough system resources you can grow this limit to an upper value for example: or Before release 7.
When Ora2Pg detect a table with some BLOB it will automatically reduce the value of this directive by dividing it by 10 until his value is below Install the SportsDB sample database. Learn how to use Firebase through building a chat app.
