1.6    Configure Replicat process in target system

1.6.1  Create GLOBALS parameter in target system

Edit GLOBALS(upper case) parameter file to indicate checkpoint table

GGSCI (rhel102.oracle.com) 11> edit params ./GLOBALS

Add:

CHECKPOINTTABLE ogg.ggschkpt

Verify:

[oracle@rhel102 ~]$ ll /u01/app/oracle/ggs/11.2.1/GLOBALS

-rw-rw-rw- 1 oracle oinstall 29 Jan  5 10:17 /u01/app/oracle/ggs/11.2.1/GLOBALS

 

For GLOBALS configuration take effect, we must exit GGSCI session:

GGSCI (rhel102.oracle.com) 14> exit

 

Add replicat checkpoint table in target system:

[oracle@rhel102 11.2.1]$ ggsci

GGSCI (rhel102.oracle.com) 1> dblogin userid ogg,password ogg

Successfully logged into database.

 

GGSCI (rhel102.oracle.com) 2> add checkpointtable

 

No checkpoint table specified, using GLOBALS specification (ogg.ggschkpt)...

 

Successfully created checkpoint table ogg.ggschkpt.

 

 

1.6.2  Edit Delivery process parameter rora_1

Add Replicat group:

GGSCI (rhel102.oracle.com) 5> add replicat rora_1,exttrail ./dirdat/ra

REPLICAT added.、

 

Edit replicat process RORA_1 parameter:

GGSCI (rhel102.oracle.com) 4> edit params rora_1

Add:

1.8    Limitation and Process

1.8.1  Column Width differs in different encoding

In zhs16gbk encoding, two bytes represents one chinese character. However, in AL32UTF8 encoding three bytes represents one chinese character. Therefore, if we INSERT 10 chinese characters in source system (zhs16gbk), which actually occupies 20 bytes, it will become 30 bytes in target system (AL32UTF8). If the column maximum width is 20 bytes, The INSERT operation can succeed in source system, but fail in target system.
