Should master/slave brokers share tmp_storage directory?
It's my understanding with kahadb the store folder location is shared between
master and slave brokers using the following config:
<persistenceAdapter>
<kahaDB directory="/mystore/kahadb"/>
</persistenceAdapter>
Why is it that temp storage does not use the same, shared location? By
default, the location for tmp_storage appears to be local to the broker
itself:
2017-10-11 11:57:30,424 [AMQ-1-thread-1 ] INFO PListStoreImpl
- PListStore:
[/opt/activemq/data/amqdata/seattlebroker-a1/tmp_storage] started
2017-10-11 11:57:30,603 [AMQ-1-thread-1 ] DEBUG KahaDBStore
- Store OpenWire version configured as: 6
For master/slave broker groups, should the temp storage location be shared
with explicit config like this?
<broker tmpDataDirectory="/mystore/kahadb/tmp_storage"/>

No, it should not be shared between brokers.
The temp store is for holding content that overflows from the memory store.
The memory store contains only non-persistent messages, which do not
survive a broker restart (or a failover), so the temp store should not
either.
