#if error should to do
ERROR at line 1:
ORA-38706: Cannot turn on FLASHBACK DATABASE logging.
ORA-38709: Recovery Area is not enabled.
解决方法：
1、通过oerr ora 38709查询，提示如下：

38709, 00000, "Recovery Area is not enabled."
// *Cause:  An ALTER DATABASE FLASHBACK ON command failed because the
//          Recovery Area was not enabled.
// *Action: Set DB_RECOVERY_FILE_DEST to a location and retry.

从提示很清楚的看出来，oracle是需要我们去设置DB_RECOVERY_FILE_DEST参数，这个代表FRA的存储路径

2、设置DB_RECOVERY_FILE_DEST这个参数前必须先设置DB_RECOVERY_FILE_DEST_SIZE，这个是FRA空间大小

3、设置这两个参数

SQL> alter system set db_recovery_file_dest_size=5G;

SQL> alter system set db_recovery_file_dest='/data/ggsdata/fras';

#有可能需要设置STREAMS_POOL_SIZE，空间设置计算公式如下
#Managing Server Resources
#In integrated mode, Extract interacts with an underlying logmining server in the source database and Replicat interacts with an inbound server in the target database. This section provides guidelines for managing the shared memory consumed by the these servers.

#The shared memory that is used by the servers comes from the Streams pool portion of the System Global Area (SGA) in the database. Therefore, you must set the database initialization parameter STREAMS_POOL_SIZE high enough to keep enough memory available for the number of Extract and Replicat processes that you expect to run in integrated mode. Note that Streams pool is also used by other components of the database (like Oracle Streams, Advanced Queuing, and Datapump export/import), so make certain to take them into account while sizing the Streams pool for Oracle GoldenGate.

#By default, one integrated capture Extract requests the logmining server to run with MAX_SGA_SIZE of 1GB and a PARALLELISM of 2. Thus, if you are running three Extracts in integrated capture mode in the same database instance, you need at least 3 GB of memory allocated to the Streams pool. As best practice, keep 25 percent of the Streams pool available. For example, if there are three Extracts in integrated capture mode, set STREAMS_POOL_SIZE to the following:

#3 GB + (3 GB * 0.25) = 3.75 GB
SQL> alter system set streams_pool_size=64m scope=both;

#if error should to do
ERROR at line 1:
ORA-38706: Cannot turn on FLASHBACK DATABASE logging.
ORA-38709: Recovery Area is not enabled.
解决方法：
1、通过oerr ora 38709查询，提示如下：

38709, 00000, "Recovery Area is not enabled."
// *Cause:  An ALTER DATABASE FLASHBACK ON command failed because the
//          Recovery Area was not enabled.
// *Action: Set DB_RECOVERY_FILE_DEST to a location and retry.

从提示很清楚的看出来，oracle是需要我们去设置DB_RECOVERY_FILE_DEST参数，这个代表FRA的存储路径

2、设置DB_RECOVERY_FILE_DEST这个参数前必须先设置DB_RECOVERY_FILE_DEST_SIZE，这个是FRA空间大小

3、设置这两个参数

SQL> alter system set db_recovery_file_dest_size=5G;

SQL> alter system set db_recovery_file_dest='/data/ggsdata/fras';

#有可能需要设置STREAMS_POOL_SIZE，空间设置计算公式如下
#Managing Server Resources
#In integrated mode, Extract interacts with an underlying logmining server in the source database and Replicat interacts with an inbound server in the target database. This section provides guidelines for managing the shared memory consumed by the these servers.

#The shared memory that is used by the servers comes from the Streams pool portion of the System Global Area (SGA) in the database. Therefore, you must set the database initialization parameter STREAMS_POOL_SIZE high enough to keep enough memory available for the number of Extract and Replicat processes that you expect to run in integrated mode. Note that Streams pool is also used by other components of the database (like Oracle Streams, Advanced Queuing, and Datapump export/import), so make certain to take them into account while sizing the Streams pool for Oracle GoldenGate.

#By default, one integrated capture Extract requests the logmining server to run with MAX_SGA_SIZE of 1GB and a PARALLELISM of 2. Thus, if you are running three Extracts in integrated capture mode in the same database instance, you need at least 3 GB of memory allocated to the Streams pool. As best practice, keep 25 percent of the Streams pool available. For example, if there are three Extracts in integrated capture mode, set STREAMS_POOL_SIZE to the following:

#3 GB + (3 GB * 0.25) = 3.75 GB
SQL> alter system set streams_pool_size=64m scope=both;
