Additional /schemacompare Arguments

This topic gives detailed description of command line switches and examples of their usage.

Arguments

To get more information on switches related to schema comparison in the command line interface, you can type:

C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /?

Note

The path to the executable file will differ depending on how you have installed the Studio - as a standalone tool or as part of the dbForge Edge bundle. Make sure that you have specified a correct path. If you have installed the Studio as part of dbForge Edge, change the path accordingly:

C:\Program Files\Devart\dbForge Edge\dbForge Studio for Oracle>dbforgeoracle.com

Below all switches of this option are described, together with usage examples.

Argument Action and Usage
/compfile This switch is used to load command line settings from the comparison project file, *.scomp. Command usage looks like:
/compfile:<path>
Example of using a file with comparison settings, saved earlier: C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /compfile:"D:\workDir\OSC1vsOSC2.scomp"
/groupby This switch is used when generating comparison reports. use it to group objects in such report. Command usage looks like:
/groupby:<none/status/objecttype>
The following example shows how to compare schemas using settings from the file, generate comparison report, and group objects in the report by type:
C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /compfile:"OSC1vsOSC2.scomp" /report:"report.txt" /reportformat:HTML /groupby:objecttype
/log Use this switch if you want to generate comparison log file in a specified directory. Command usage looks like:
/log:<filepath>
The following example shows how to compare schemas using settings from the file and write log to the specified file:
C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /compfile:"OSC1vsOSC2.scomp" /log:"D:\sync.log
options You can specify some comparison and synchronization options directly in the command line interface. See the list of available options and learn how to use them in the Command Line Options for /schemacompare Operation topic.
/report and /reportformat You can generate schema comparison report in .html or .xls format. If you specify file format in the output file name in the /report switch, it is not necessary to use the /reportformat switch. Commands usage looks like:
/report:<filepath>
/reportformat:<HTML|XLS>
The following example shows how to compare schemas using settings from a file, generate report to the specified file in the HTML format:
C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /compfile:"OSC1vsOSC2.scomp" /report:"report.txt" /reportformat:HTML
/source You can specify source database schema for comparison and synchronization in the command line. It is possible to use several options for defining the schema.
To connect to a server via Oracle client, type:
server:<server_alias> [home:<oracle_home_name>] user:<user_name> password:<pw> mode:[normal/sysdba/sysoper]
To connect to a server without using Oracle client (direct connection), type:
host:<machine_name> [port:<port_number>] SID:<oracle_service_ID> user:<user_name> password:<password> mode:[normal/sysdba/sysoper]
To specify full connection string with additional parameters, type:
connection:<connection_string>
To specify a snapshot file path, type:
snapshot:<filepath>
/target You can specify target database schema for comparison and synchronization in the command line. It is possible to use several options for defining the schema.
To connect to a server via Oracle client, type:
server:<server_alias> [home:<oracle_home_name>] user:<user_name> password:<pw> mode:[normal/sysdba/sysoper]
To connect to a server without using Oracle client (direct connection), type:
host:<machine_name> [port:<port_number>] SID:<oracle_service_ID> user:<user_name> password:<password> mode:[normal/sysdba/sysoper]
To specify full connection string with additional parameters, type:
connection:<connection_string>
To specify a snapshot file path, type:
snapshot:<filepath>
/schemas You can specify schemas to compare. If you don’t, schemas specified in /source and /target will be used. Command usage looks like:
/schemas:<source_1>,<target_1>[;<source_2>,<target_2>;...]
The following example shows how to compare schemas using connection through client.
C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /source server:OraServer user:system password:pswd /target server:OraServer2 user:system password:pswd /schemas:OSC1,OSC2"
/sync You can perform schema synchronization from the command line interface. If you specify output file for synchronization, only synchronization script will be generated. Command usage looks like:
/sync[:path]
The following example shows how to compare schemas using settings from the file saved before, and save synchronization script:
C:\Program Files\Devart\dbForge Studio for Oracle>dbforgeoracle.com /schemacompare /compfile:"OSC1vsOSC2.scomp" /sync:"D:\compare_result.sql"

Usage Examples

  • Compare schemas using settings from a file saved earlier:
/schemacompare /compfile:"D:\workDir\OSC1vsOSC2.scomp"
  • Compare and synchronize schemas using connection through the client. Log will be written to the specified file:
/schemacompare /source server:OraServer user:system password:pswd /target server:OraServer2 user:system password:pswd /schemas:OSC1,OSC2 /sync /log:"D:\sync.log"
  • Compare specified schemas and save the synchronization script to the D:\compare_result.sql file; the first connection is created using direct mode, the second connection is established through the client:
/schemacompare /source host:oraHost port:1521 SID:orcl user:sys password:manager mode:sysdba /target server:OraServer user:system password:pswd /schemas:SC1,SC2;OSC1,OSC2 /sync:"D:\compare_result.sql"
  • Compare and synchronize schemas using settings from the file, ignore case and foreign keys during comparison; generate a report to the specified file in the html format:
/schemacompare /compfile:"OSC1vsOSC2.scomp" /icase:yes /IgnoreForeignKeys:yes /report:"report.txt" /reportformat:HTML /groupby:objecttype /incsettings:T /sync
