1. Create a share to be used by both compute nodes. In this demo we created one as follows.
/u01/Middleware
2. Install WLS software onto the share as shown below.
[oracle@auxlcn07 1034]$ pwd /u01/Middleware/1034 [oracle@auxlcn07 1034]$ d total 148 drwxr-xr-x+ 7 oracle oinstall 464 Jun 30 21:25 modules/ drwxr-xr-x+ 8 oracle oinstall 9 Jun 30 21:25 utils/ drwxr-x---+ 7 oracle oinstall 9 Jun 30 21:25 jrockit_160_22_D1.1.1-3/ -rw-r--r--+ 1 oracle oinstall 623 Jun 30 21:25 ocm.rsp -rw-r--r--+ 1 oracle oinstall 73475 Jun 30 21:25 registry.dat -rw-r--r--+ 1 oracle oinstall 2306 Jun 30 21:25 registry.xml -rw-r--r--+ 1 oracle oinstall 26 Jun 30 21:25 .home drwxr-xr-x+ 8 oracle oinstall 13 Jun 30 21:25 ./ drwxr-xr-x+ 9 oracle oinstall 11 Jun 30 21:25 wlserver_10.3/ drwxr-xr-x+ 6 oracle oinstall 9 Jun 30 21:25 coherence_3.6/ -rw-rw----+ 1 oracle oinstall 192 Jul 1 08:25 domain-registry.xml drwxr-xr-x+ 2 oracle oinstall 12 Jul 1 17:16 logs/ drwx------+ 6 oracle oinstall 6 Jul 4 15:56 ../
3. Now we can create a PRODUCTION domain into a share in a directory as follows "/u01/Middleware/domains/1034/acs_dom". Ensure you create a machine for each compute node and ensure you place the managed servers you wish on each compute node in the domain config screens.
[oracle@auxlcn07 acs_dom]$ d total 23 drwxr-xr-x+ 4 oracle oinstall 4 Jul 1 08:25 ../ drwxr-x---+ 2 oracle oinstall 3 Jul 1 08:25 autodeploy/ drwxr-x---+ 2 oracle oinstall 3 Jul 1 08:25 console-ext/ drwxr-x---+ 2 oracle oinstall 3 Jul 1 08:25 lib/ drwxr-x---+ 2 oracle oinstall 6 Jul 1 08:25 security/ -rw-r-----+ 1 oracle oinstall 650 Jul 1 08:25 startManagedWebLogic_readme.txt drwxr-x---+ 2 oracle oinstall 7 Jul 1 08:25 init-info/ -rw-r-----+ 1 oracle oinstall 462 Jul 1 08:25 fileRealm.properties -rwxr-x---+ 1 oracle oinstall 252 Jul 1 08:25 startWebLogic.sh* drwxr-x---+ 10 oracle oinstall 12 Jul 1 08:26 config/ drwxr-x---+ 12 oracle oinstall 16 Jul 1 08:29 ./ drwxr-----+ 2 oracle oinstall 2 Jul 1 10:50 pending/ -rw-r-----+ 1 oracle oinstall 32 Jul 1 10:50 edit.lok drwxr-----+ 2 oracle oinstall 2 Jul 1 10:50 tmp/ drwxr-----+ 8 oracle oinstall 8 Jul 1 14:10 servers/ drwxr-x---+ 5 oracle oinstall 11 Jul 1 15:38 bin/
Note: No need for pack/unpack given we are using a share.
4. In this demo we want to create a node manager process on each compute node sharing the same domain directory. To do this we simply create seperate directories for each on our compute nodes and copy a set of node manager files available in the default $WLS_HOME/wlserver_10.3/common/nodemanager directory.
[oracle@auxlcn07 nodemanager]$ pwd /u01/Middleware/domains/1034/nodemanager [oracle@auxlcn07 nodemanager]$ d total 6 drwxr-xr-x+ 4 oracle oinstall 4 Jun 30 21:54 ./ drwxr-xr-x+ 4 oracle oinstall 4 Jul 1 08:25 ../ drwxr-xr-x+ 2 oracle oinstall 8 Jul 1 14:27 node08/ drwxr-xr-x+ 2 oracle oinstall 9 Jul 1 15:29 node07/
Example of node07 files
[oracle@auxlcn07 node07]$ pwd /u01/Middleware/domains/1034/nodemanager/node07 [oracle@auxlcn07 node07]$ d total 30 drwxr-xr-x+ 4 oracle oinstall 4 Jun 30 21:54 ../ -rw-r-----+ 1 oracle oinstall 130 Jul 1 08:44 nm_data.properties -rw-r-----+ 1 oracle oinstall 77 Jul 1 11:20 nodemanager.domains -rw-r--r--+ 1 oracle oinstall 164 Jul 1 11:28 nodemanager.properties -rwxr-x---+ 1 oracle oinstall 4378 Jul 1 13:23 startNodeManager.sh* -rw-r-----+ 1 oracle oinstall 1379 Jul 1 14:02 nodemanager.log.1 -rw-r-----+ 1 oracle oinstall 0 Jul 1 14:28 nodemanager.log.lck -rw-r-----+ 1 oracle oinstall 15618 Jul 1 14:29 nodemanager.log drwxr-xr-x+ 2 oracle oinstall 9 Jul 1 15:29 ./
nodemanager.properties example, the HOME will differ in the node08 file.
NodeManagerHome=/u01/Middleware/domains/1034/nodemanager/node07
StartScriptEnabled=true
StopScriptEnabled=true
5. Edit startNodeManager.sh to include node manager home location now it's moved
away from WLS_HOME. Example for node07.
NODEMGR_HOME="/u01/Middleware/domains/1034/nodemanager/node07"
6. Start both node managers from there directories on each compute node, example for node07.
/u01/Middleware/domains/1034/nodemanager/node07/startNodeManager.sh
7. For the ADMIN SERVER node ensure we set the following in "startWebLogic.sh".
# START WEBLOGIC
JAVA_OPTIONS="${JAVA_OPTIONS} -Dweblogic.security.SSL.ignoreHostnameVerification=true"
echo "starting weblogic with Java version:"
8. Start admin server, here we use node07.
/u01/Middleware/domains/1034/acs_dom/bin/startWebLogic.sh
9. Log into the admin console
10. Ensure the node manager processes are available from each machine and reachable.
11. Start all managed servers, once you ensure the node manager is reachable. I prefer to start managed servers from the command line but given we have 2 node managers on the compute nodes we can use that through the admin console.
Example of such a setup.
