Move object or schema from one
replicate group to another replicate group
Note
1)
We
are moving one schema from the Replicat(R0000050) to Replicat(R0000018)
2)
Schema
name CG_DATA
3)
Take
the backup of all the param which are planned to modify during the change
#1 Add table on the new extract & Pump process
GGSCI> stop E0000018
GGSCI> stop P0000018
Add the below line in the param file(Extract & Pump)
TABLE CG_DATA.*;
GGSCI> start E0000018
GGSCI> start P0000018
Note: make sure that new schema object are seen in the
extract & pump stats
To see it
GGSCI> STATS EXTRACT
E0000018,TABLE CG_DATA.*
GGSCI> STATS EXTRACT
P0000018,TABLE CG_DATA.*
#2 Make sure Extract & PUMP & Replicat (R0000050) lag
is “0”
GGSCI> info R0000050

Note: if the Extract & PUMP &
Replicat lag are not “0”, then we have to make sure it is LAG is zero.
#3 Stop the Replicat(R0000050 & R0000018 ) and find the
CSN number from replicat R0000050 trail file
A)
Stop
the replicat process
GGSCI> stop R0000050
GGSCI> stop R0000018
B)
Remove
the schema entire from the replicat(R0000050)
C)
You
need to find the CSN number from the trail file of replicat(R0000050) using the
logdump utility.
Note:
CASE#1 In our case,
after we stopped there is no update to the trail file; so we have followed the
below process.

D)
Add
the schema entire to the replicat(R0000018); you need to use the CSN from the
previous step
è SCN number is 2181186019822 as per
the CASE#1;
MAP CG_DATA.*, TARGET CG_DATA.*, FILTER
(@GETENV("TRANSACTION", "CSN") > 2181186019822);
E)
Start
the replicat process
GGSCI> start R0000050
GGSCI> start R0000018
F)
Check
the status with the below command
GGSCI> STATS EXTRACT
R0000018,TABLE CG_DATA.*
#4 Post movement steps
A) Once you are happy with the changes,
you can remove the schema capture from the E0000050 & P0000050.
B) You can leave the Replicat(R0000018)
running for sometime; then we can remove the filter condition from the param
file
Before modification
MAP CG_DATA.*, TARGET
CG_DATA.*, FILTER
(@GETENV("TRANSACTION", "CSN") > 2181186019821);
After Modification
MAP CG_DATA.*, TARGET CG_DATA.*;
C) You can monitor the complete process
for next 2 hours.
