utility. (See
"ttAdmin"
in
Oracle TimesTen In-Memory Database API
Reference Guide
.) In order to unload a data store:
1.
Disconnect all applications from the data store.
2.
In this example, the data store
original
is from the previous release.
The data store
upgrade
is in the new release. If replication has been
started, pause replication on the data stores, and then stop replication on
the data store that you are unloading from memory, using the
commands:
ttRepAdmin -receiver -name upgrade -state pause original
ttRepAdmin -receiver -name original -state pause upgrade
ttAdmin -repStop upgrade
3.
If the cache agent has been started for the data store, stop the cache
agent with the command:
ttAdmin -cacheStop upgrade
4.
Verify that the RAM policy allows the data store to be unloaded. If the
RAM policy is set to
manual
, unload the data store using the command:
ttAdmin -ramUnload upgrade
If the RAM policy is set to
always
or
inUse
, change it to
manual
. If the
RAM policy is
inUse
and a grace period is set, set the grace period to 0
or wait for the grace period to elapse.
5.
Use the
ttStatus
utility to verify that the data store has been unloaded
from memory. (See
"ttStatus"
in
Oracle TimesTen In-Memory Database
API Reference Guide
.)
Moving to a new patch release of TimesTen
All applications concurrently connected to a data store must be directly
linked to a TimesTen ODBC driver of the same major release. TimesTen
data stores from different patch releases are structurally equivalent or
identical. For example, when upgrading from release 7.0.10.0.0 to
7.0.20.0.0, you do not need to migrate your existing data stores.
However, during the installation of a new major or minor release, you
should disconnect your application and stop the TimesTen daemon. If
you have not explicitly performed these steps, the prior release's
TimesTen daemon process is stopped, effectively disconnecting all
applications from the data store. While preparing for the upgrade, make
sure that all data stores are unloaded from memory before upgrading
TimesTen.

memory, see
