GG配置Oracle同步到SQLServer
源端目标端准备一张测试用的表。 Oracle源端: drop table ggmgr.t1; create table ggmgr.t1( id int primary key, name varchar2(50), time date);
Sqlserver目标端: BEGIN TRANSACTION SET QUOTED_IDENTIFIER ON SET ARITHABORT ON SET NUMERIC_ROUNDABORT OFF SET CONCAT_NULL_YIELDS_NULL ON SET ANSI_NULLS ON SET ANSI_PADDING ON SET ANSI_WARNINGS ON COMMIT BEGIN TRANSACTION GO CREATE TABLE dbo.Table_1 ( id numeric(18, 0) NOT NULL, name nvarchar(40) NULL, time date NULL ) ON [PRIMARY] GO ALTER TABLE dbo.Table_1 ADD CONSTRAINT PK_Table_1 PRIMARY KEY CLUSTERED ( id ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO ALTER TABLE dbo.Table_1 SET (LOCK_ESCALATION = TABLE) GO COMMIT

Oracle端(配置extract进程) dblogin userid ggmgr,password oracle add trandata test.n
edit param e_erp extract e_erp userid ggmgr,password oracle setenv(ORACLE_SID=orcl) exttrail ./dirdat/dd table ggmgr.t1;
添加extract进程 add extract e_erp,tranlog,begin now 创建本地trail文件(并不是物理上真的创建),这个e_erp要之前就按这个名称添加了extract进程。 add exttrail ./dirdat/dd, extract e_erp
配置data pump进程 edit params d_erp extract d_erp userid ggmgr,password oracle rmthost 10.60.17.48,mgrport 7809 rmttrail D:\gg\dirdat\dd table ggmgr.t1;
add extract d_erp, exttrailsource /home/ora/gg/dirdat/dd add rmttrail D:\gg\dirdat\dd, extract d_erp
sqlserver端(配置replicat进程)
传送defgen工具定义文件
在SQLServe目标端,配置globals文件,指定用某个checkpoint表 /ggsci edit params ./GLOBALS CHECKPOINTTABLE MASTER.DBO.GG_CHECKPOINT_TAB
globals文件必须在在$GGS_HOME目录下,即软件根目录下,如果已经存在一个,可以先move走它。
为目标端配置checkpoint table dblogin sourcedb mssql(这个名称,是我们定义在ODBC数据源的那个代表某给sqlserver服务的描述符) add checkpointtable master.dbo.gg_checkpoint_tab
配置replicat进程 EDIT PARAMS R_ERP replicat r_erp sourcedb mssql sourcedefs D:\gg\dirdef\defgen.def reperror default,discard discardfile ./dirrpt/r_erp.dsc,append,megabytes 50 map ggmgr.t1, target fwy.dbo.t1;
discardfile参数推荐用这个参数,对于数据库拒绝的数据,会反映到这个文件中
增加replicat进程 add replicat r_erp, exttrail D:\gg\dirdat\dd
然后用defgen工具,将表定义传送到目标端
源端跑起来 start e_bom start d_bom 目标端 start replicat r_bom view report r_erp
如果想过滤某些列,什么都不用做。例如源端有7个字段,目标端有6个,同名字段自动匹配,没的会自动去掉。但如果字段名有些一样,有些不同呢? map ggmgr.t3, target fwy.dbo.t3, colmap ( usedefaults, --意味着字段名相同就用默认的复制 target_col = source_col); --目标表字段名是target_col,从源端的字段名是source_col的字段处抽取。

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Deleting all data in Oracle requires the following steps: 1. Establish a connection; 2. Disable foreign key constraints; 3. Delete table data; 4. Submit transactions; 5. Enable foreign key constraints (optional). Be sure to back up the database before execution to prevent data loss.

Oracle Invalid numeric errors may be caused by data type mismatch, numeric overflow, data conversion errors, or data corruption. Troubleshooting steps include checking data types, detecting digital overflows, checking data conversions, checking data corruption, and exploring other possible solutions such as configuring the NLS_NUMERIC_CHARACTERS parameter and enabling data verification logging.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

Oracle database paging uses ROWNUM pseudo-columns or FETCH statements to implement: ROWNUM pseudo-columns are used to filter results by row numbers and are suitable for complex queries. The FETCH statement is used to get the specified number of first rows and is suitable for simple queries.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.
