Good day.
We have added transactions using Geode and are now getting this exception
as soon as we try and lookup something from a region:

We get this error when trying to access the RootMapHolder region setup
below.
We have a client connecting to a server. The relevant client config is
basically:
<bean id="pdxSerializer" class="org.rdb.session.geode.RDBGeodeSerializer">
<constructor-arg value="org.rdb.*,net.lautus.*"/>
</bean>
<util:properties id="gemfire-props">
<prop key="log-level">config</prop>
</util:properties>
<gfe:client-cache properties-ref="gemfire-props"
pdx-serializer-ref="pdxSerializer"/>
<gfe:transaction-manager copy-on-read="true"/>
<gfe:pool>
<gfe:server host="localhost" port="40407"/>
</gfe:pool>
<gfe:client-region id="org.rdb.internal.session.rootmap.RootMapHolder"
shortcut="CACHING_PROXY_OVERFLOW"
ignore-if-exists="true"/>
On the server we have this config part:
util:properties id="gemfire-props">
<prop key="log-level">info</prop>
<prop key="mcast-port">0</prop>
</util:properties>
<gfe:cache properties-ref="gemfire-props"
pdx-serializer-ref="pdxSerializer" pdx-persistent="true"
pdx-disk-store="pdx-disk-store" />
<gfe:cache-server auto-startup="true" bind-address="localhost" port="40407"
host-name-for-clients="localhost"
max-connections="1"/>
<bean id="pdxSerializer" class="org.rdb.session.geode.RDBGeodeSerializer">
<constructor-arg value="org.rdb.*,net.lautus.*"/>
</bean>
<gfe:replicated-region id="org.rdb.internal.session.rootmap.RootMapHolder"
disk-store-ref="testDiskStore"
persistent="true">
<!--<gfe:cache-listener ref="cacheListener"/>-->
<gfe:eviction type="HEAP_PERCENTAGE" action="OVERFLOW_TO_DISK"/>
</gfe:replicated-region>
<gfe:disk-store id="testDiskStore">
<gfe:disk-dir location="geode-test/testDiskStore"/>
</gfe:disk-store>
<gfe:disk-store id="pdx-disk-store">
<gfe:disk-dir location="geode-test/pdx"/>
</gfe:disk-store>
We are getting and starting transactions via:
transactionManager = context.getBean("gemfireTransactionManager",
GemfireTransactionManager.class);
cacheTransactionManager =
transactionManager.getCache().getCacheTransactionManager();
cacheTransactionManager.begin();
By debugging I can see we start only one transaction. But as soon as we
access the first Region it throws this error.
We are not using annotations and Spring repositories as we are trying to
add Geode to an existing project that has no Spring, Spring Data or JPA
support.
Are we using transactions incorrectly? Or is this a Region setup issue?
Any help would be appreciated. Can provide more detail if required.
Kindly
Pieter
