For developers, it is possible to add your own custom option(s) in the Perl script ora2pg as any configuration directive from nf can be passed in lower case to the new Ora2Pg object instance. You can take a look at the PostgreSQL supported character sets here: ml plsql to plpgsql conversion Automatic code conversion from Oracle plsql to PostgreSQL plpgsql is a work in progress in Ora2Pg and surely you will always have manual work. For exemple: string_constant_regexp placeholder value". For example: sysusers will add users internal and sysdba to the schema exclusion list. It is impossible to know the exact century that must be used, so by default any year below 49 will be added to 2000 and others to 1900. Standard_conforming_strings This controls whether ordinary string literals. The Orafce library can be found here: m/orafce/orafce By default Ora2pg rewrite add_month add_year date_trunc and to_char functions, but you may prefer to use the orafce version of these function that do not need any code transformation.

Enable it if you are exporting to GreenPlum PostgreSQL database. PG_supports_identity Enable this directive if you have PostgreSQL 10 to use identity columns instead of serial or bigserial data type. dump_as_csv : As above but force ora2pg to dump report in CSV. 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: 100000 or 1000000.
This will only works with export to file and when -J or oracle_copies is not set or default. Lobmaxsize, offset, offset dbms_leclose(src_file return filecontent; END; This function is only created if Ora2Pg found a table with a bfile column and that the destination type is bytea (the default).

As a result, every next_run_date evaluated using this schedule would have a value of 45 minutes past the hour. With_OID Activating this directive will force Ora2Pg to add with (oids) when creating tables or views as tables. If the value is upper than 1, all srid will be forced to this value, in this case default_srid will not be used when Oracle returns a null value and the value will be forced to convert_srid. Default_parallelism_degree You can force Ora2Pg to use parallel(tbname, degree) hint in each query used to export data from Oracle by setting a value upper than 1 to this directive. Here is a full example of a CSV databases list file: The CSV field separator must be a comma. Next Run Date: 01-JAN-2004 04:04:32 Next Run Date: 01-JAN-2004 05:04:32 Next Run Date: 01-JAN-2004 06:04:32 Next Run Date: 01-JAN-2004 07:04:32 Next Run Date: 01-JAN-2004 08:04:32 Run job Every hour, on the hour.?trunc(sysdate,?HH24?) 1/24??trunc(systimestamp,?HH24?) 1/24?

If enabled, Ora2Pg will use the Oracle function sdo_p_oracle_srid_to_epsg to convert all srid. Note that bitmap index(es) will be exported as b-tree index(es) if any.
Noescape By oracle pl/sql work from home jobs default all data that are not of type date or time are escaped. audit_user list : Comma separated list of usernames to filter queries in the DBA_audit_trail table. Test sequence count oracledb:sequence:1 postgres:sequence:0 errors sequence count sequence does not have the same count in Oracle (1) and in PostgreSQL (0).

You can find some slide about this in a presentation given at : Test the migration The type of action called test allow you to check that all objects from Oracle database have been created under oracle pl/sql work from home jobs PostgreSQL. Table partition 8 0 Partitions are exported using table inheritance and check constraint.
c -conf file : Set an alternate configuration file other than the default /etc/ora2pg/nf. Sql will import content of file output. The limit is the number of cores on your machine. It then adds the plpgsql code to create tree functions: create_materialized_view(text, text, text) used to create a materialized view drop_materialized_view(text) used to delete a materialized view used to refresh a view then it adds the SQL code to create. Note that performance might be improved by updating stats on oracle: begin dbms_ther_schema_stats dbms_ther_database_stats dbms_ther_dictionary_stats END; Generate a migration template The two options -project_base and -init_project when used indicate to ora2pg that he has to create a project template. It will use a Pure Perl library to convert the SDO_geometry data into a WKT representation, the translation is done on Ora2Pg side. FTS_config Use this directive to force text search configuration to use. When used this directive prevent the export of users unless it is set to user. See -cost_unit_value to change the unit value at command line. This is usable only during insert or copy export type.
