Enable dynamic cache service multi-cell and multi-core group invalidation with scripting
Use the dynacacheJMSSIB.py script to enable dynamic cache service multi-cell and multi-core group invalidation. Configure the external cache adapter and service integration bus infrastructure in multiple cells. To work correctly, the script must be executed from...
PROFILE_HOME/bin
We must also ensure that :
- Each cell or core group contains a cluster hosting a production application. The same production application has to be used in both cells or core groups to ensure invalidation IDs are processed correctly.
- A separate cluster of two servers is created in each cell or core group to host the service integration bus. The members of this cluster cannot have a RemoteJMSInvalidator external cache group defined. If a RemoteJMSInvalidator external cache group is defined for these cluster members, an infinite loopback condition occurs where invalidations are repeatedly send back and forth between cells.
- A datasource is defined and is accessible from both service integration bus cluster members. If the database is shared by both cells, ensure a unique database name is used when defining each the datasource for each cell.
- Each cell or core group contains a replication domain containing both the service integration bus cluster and all of the clusters hosting the production applications.
The dynacacheJMSSIB.py script configures each cell or core group in three steps:
- Inbound JMS/service integration bus configuration.
Inbound JMS/service integration bus configuration includes:
- Create a service integration bus and configuring the service integration bus destination.
- Create a Java Message Service (JMS).
- Configure the JMS activation specification
- Install the WAS_INSTALL_ROOT/installables/DynacacheMessageHandler.ear message driven bean on the service integration bus cluster.
- Outbound JMS/service integration bus configuration.
Outbound JMS/service integration bus configuration includes configuring the JMS queue connection factory to communicate with a remote cell.
- External cache group configuration.
External cache group configuration includes configuring an external cache group and external cache adapter on each cluster member hosting the production applications.

Example 1: Multiple cells
This example shows how the script is used to configure two cells, Cell1 and Cell2, where both cells host the same application,ApplicationA.
Cell1 ProductionCluster1 (hosts ApplicationA) SIBCluster1 node1/sib1 (service integration bus member) SIB_ENDPOINT_ADDRESS=7777 hostname=host1.com node1b/sib2 (service integration bus member) SIB_ENDPOINT_ADDRESS=7776 hostname=host11.com ReplicationDomain (contains ProductionCluster1 members and SIBCluster1 members) Service Integration Bus Data Source1 JNDI name = jdbc/SIBCluster1DataSourceCell2 ProductionCluster2 (hosts ApplicationA) SIBCluster2 node2/sib1 (service integration bus member) SIB_ENDPOINT_ADDRESS=8888 hostname=host2.com nodesb/sib2 (service integration bus member) SIB_ENDPOINT_ADDRESS=8889 hostname=host22.com ReplicationDomain (contains ProductionCluster2 members and SIBCluster2 members) Service Integration Bus Data Source2 JNDI name = jdbc/SIBCluster2DataSourceEnable dynamic cache service cell invalidation support for Cell1 and Cell2.
- Configure inbound JMS/service integration bus for Cell1:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheInSIB --cluster=SIBCluster1 --datasourceJNDI=jdbc/SIBCluster1DataSource
- Configure inbound JMS/service integration bus for Cell2:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheInSIB --cluster=SIBCluster2 --datasourceJNDI=jdbc/SIBCluster2DataSource
- Configure outbound JMS/service integration bus for Cell1:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheOutSIB --remoteCellSIBServers=host2.com:8888,host22.com:8889 --remoteCellID=Cell2
- Configure outbound JMS/service integration bus for Cell2:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheOutSIB --remoteCellSIBServers=host1.com:7777,host11.com:7776 --remoteCellID=Cell1
- Configure external cache group/adapters for Cell1:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheECA --cluster=ProductionCluster1 --remoteCellID=Cell2
- Configure external cache group/adapters for Cell2:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheECA --cluster=ProductionCluster2 --remoteCellID=Cell1
This example shows how the script is used to configure a single cell containing multiple core groups. The core groups host the same application (ApplicationA).
CoreGroup1 ProductionCluster1 (hosts ApplicationA) SIBCluster1 node1/sib1 (service integration bus member) SIB_ENDPOINT_ADDRESS=7777 hostname=host1.com node1b/sib2 (service integration bus member) SIB_ENDPOINT_ADDRESS=7776 hostname=host11.com ReplicationDomain (contains ProductionCluster1 members and SIBCluster1 members) Service Integration Bus Data Source1 JNDI name = jdbc/SIBCluster1DataSourceCoreGroup2 in Cell2 is also hosting ApplicationA and has the following topology:
CoreGroup2 ProductionCluster2 (hosts ApplicationA) SIBCluster2 node2/sib1 (service integration bus member) SIB_ENDPOINT_ADDRESS=8888 hostname=host2.com nodesb/sib2 (service integration bus member) SIB_ENDPOINT_ADDRESS=8889 hostname=host22.com ReplicationDomain (contains ProductionCluster2 members and SIBCluster2 members) Service Integration Bus Data Source2 JNDI name = jdbc/SIBCluster2DataSourceEnable dynamic cache service core group invalidation support for CoreGroup1 and CoreGroup2.
- Configure inbound JMS/service integration bus for CoreGroup1:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheInSIB --localCellID=Cell1/CoreGroup1 --cluster=SIBCluster1 --datasourceJNDI=jdbc/SIBCluster1DataSource
- Configure inbound JMS/service integration bus for CoreGroup2:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheInSIB --localCellID=Cell1/CoreGroup2 --cluster=SIBCluster2 --datasourceJNDI=jdbc/SIBCluster2DataSource
- Configure outbound JMS/service integration bus for CoreGroup1:
./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheOutSIB --localCellID=Cell1/CoreGroup1 --remoteCellSIBServers=host2.com:8888,host22.com:8889 --remoteCellID=Cell1/CoreGroup2

./wsadmin.sh -lang jython -f ../../../util/dynacacheJMSSIB.py --setup=dynacacheECA --cluster=ProductionCluster1 --localCellID=Cell1/CoreGroup1 --remoteCellID=Cell1/CoreGroup2
