GG Configuring Oracle Synchronization to SQL Server
Prepare a test table for the source end target side. Oracle Source: Drop table Ggmgr.t1;create table ggmgr.t1 (id int primary key,name varchar2 (), time date);
SQL Server target end: BEGIN transactionset quoted_identifier ONSET ARITHABORT ONSET numeric_roundabort OFFSET Concat_null_ Yields_null ONSET ansi_nulls ONSET ansi_padding ONSET ansi_warnings oncommitbegin transactiongocreate TABLE dbo.

Transfer Defgen tool definition file
on the Sqlserve target side, configure the Globals file to specify a checkpoint table/ggsciedit params./globalscheckpointtable MASTER. Dbo. Gg_checkpoint_tab
The globals file must be in the $ggs_home directory, that is, under the software root directory, if one already exists, you can move it first.

If you want to filter some columns, you don't have to do anything. For example, there are 7 fields on the source side, there are 6 targets, the same name field automatically matches, and no will be automatically removed. But what if the field names are somewhat different? map Ggmgr.t3, Target fwy.dbo.t3,Colmap (Usedefaults,--means that the field name is the same as the default copytarget_col = Source_col); --The target table field name is Target_col, which is extracted from fields on the source side where the field name is Source_col.
