Data Store Upgrades 99
Note: Before moving a replicated data store to another machine, you
should be experienced with TimesTen replication. We highly advise
calling TimesTen customer support for help with this procedure.
To copy a data store from one system to another with the same CPU
architecture and operating system:
1. Back up the data store on the original system using ttBackup.
2. Move the backup to the new system.
3. Reconfigure the replication scheme on any replicated data stores to
identify the new host machine. (See TimesTen to TimesTen Replication
Guide for details on how to specify a host in a replication scheme.)
4. Restore the backup using ttRestore.
For example, to move a data store from
/ds/Sales/Data with data store
name
salesdata on the source system to /data/Sales/View with data
store name
salesview on the destination system, use the following
commands. This example uses the
-o flag of ttBackup to use standard
output for the backup. Using the
-o flag, the backup is stored in a single
file, which is easily copied over the network to the other system. Once
you have copied the data store to the other system, you need to create a
data source name for convenient access to the new data store copy.
On the source system On the destination system
1.
ttBackup -o "DSN=SalesData" >
/tmp/salesbackup
2. ftp /tmp/salesbackup to the
destination system as
/tmp/salesbackup
Note: Use the ftp command in binary
mode.
3.
ttRestore -i
"DSN=SalesView" <
/tmp/salesbackup
4.
rm /tmp/salesbackup
5.
rm /tmp/salesbackup
