WAS jython scripts
Ever want to script the installation of an application that runs on IBM WebSphere Application Server? Well for all of you out there who do (and I know this is some pretty specific geek speak), there are a couple pieces that I just recently ironed out.
Increasing the Deployment Manager’s Max Heap
This is pretty easy to do in Jython in a scriptable manner:
1 2 3 4 5 |
# Increase the Max Heap of the DMGR dmgrNode = "someserver-dm" newHeap = "1024" AdminTask.setJVMMaxHeapSize('[ -nodeName '+dmgrNode+' -serverName dmgr -maximumHeapSize '+newHeap+' ]') AdminConfig.save() |
Modifying a Port
Sometimes new app servers might have port conflicts with other app servers (or anything else on the machine):
1 2 3 4 5 6 7 8 |
# Fix a conflicting port appServerName = "solrServer" serverName = "someserver" nodeName = "someserver-node1" newPort = "9091" AdminTask.modifyServerPort(appServerName, '[-nodeName '+nodeName+' -endPointName ORB_LISTENER_ADDRESS -host '+serverName+' -port '+newPort+']') AdminConfig.save() |
Create a Cluster from an existing App Server
This is also pretty easy:
1 2 3 4 5 6 7 |
# Create the Solr cluster clusterName = "SolrCluster" appServerName = "solrServer" nodeName = "someserver-node1" AdminClusterManagement.createClusterWithFirstMember(clusterName, "APPLICATION_SERVER", nodeName, appServerName) AdminConfig.save() |
Installing an Application into a Cluster
Seems almost too easy:
1 2 3 4 5 6 |
# Install the CacheMonitor application clusterName = "SolrCluster" AdminApplication.installAppWithClusterOption("CacheMonitor", "/opt/IBM/WebSphere/AppServer/installableApps/CacheMonitor.ear", clusterName) AdminConfig.save() |
I’ve got more stuff, but that’ll probably do for now.
