Can I have a space with only 1 partition?

I'm having problems with a space that has 4 partitions. When data loads from the database into the 4 partitions, they lock the database at the same time, and the load fails. So I decided to reduce the number of partitions from 4 to 1, by changing this:
-max-instances-per-vm 1 -cluster schema=partitioned-sync2backup total_members=4,1
to this:
-max-instances-per-vm 1 -cluster schema=partitioned-sync2backup total_members=1,1
in my deploy script.

But now when I run my application, I get this error, because the application still thinks there are 4 partitions:
com.gigaspaces.internal.remoting.routing.clustered.SpaceProxyLoadBalancingStrategy findActiveMember
SEVERE: Failed to find an active server for partition #2 to execute ExecuteTaskSpaceOperationRequesttask=org.openspaces.core.executor.internal.InternalSpaceTaskWrapper@3947cbb6

Other than in the deploy script, where might the number of partitions be specified?

Are you sure you completely restarted your application?

Restart LUS and GSM before you redeploy.

btw - to avoid the database lock you can use a different space and call the LOCK/UNLOCK API from the initial load to force each partition to reload its data in order and not in parallel: https://docs.gigaspaces.com/xap121/ma...
