8. 12 things,
no agenda ☺

9. #1 !
OUI / opatch
opatch for WLS

10. munz & more
New Installer
• OUI – consistent with OFM and Oracle DB!
• Java is not included!
• No console mode anymore
-> silent mode with response file
Other
options:
Vagrant
with Chef
or Puppet,
maven and
even
Dockerjava –jar fmw12.1.3.0.0_wls.jar –silent
–responseFile fullPathToRespFile –invPtrLoc /etc/oraInst.loc
10

11. munz & more
The oraInst.loc File
oraInst.loc points to product inventory:!
!
!
!
location depends on OS, e.g. OS X:!
/var/opt/Oracle
11

12. munz & more
Prerequisite Checks
12

13. munz & more
Prerequisite Checks
• CPU with 0 MHz ?!
-> wrong BIOS selection
in Virtual Box!
• swap enabled ?!
• /tmp on tempfs ?
check size in /etc/fstab"
• Ignore result of check (NOT recommended):
-ignoreSysPrereqs
13

14. munz & more
opatch
• Located in WEBLOGIC_HOME/Opatch"
• Uses oraInst.loc"
• opatch uses ORACLE_HOME variable
make sure it does not conflict with
ORACLE_HOME of an installed DB
-> different installation user
14

15. #2 !
Domain Wizard

16. munz & more
config.sh
domain location
includes domain name
-Dcom.oracle.cie.config.showProfile
enables Compact/Expanded Domain Topology Selection (mainly for OFM)
16

17. munz & more
config.sh
Oracle doc WLS
12.1.1
Instead use
WLST, unpack, maven, …
17

18. #3 !
Per Domain
Node Manager
Per Domain NM

19. munz & more
Per Domain Node Manager
• Easier setup!
• Config and logs part
of domain directory!
• Uses SSL per default!
• unpack recreates
demo certs!
• Startscript:
DOMAIN_HOME/bin/startNodeManager.sh
19

20. munz & more
Per Domain Node Manager
• DOMAIN_HOME/nodemanager contains
nodemanager.properties and
nodemanager.domains "
!
• Per machine NM still possible:
startNodeManager.sh
in WL_HOME/server/bin
20

21. munz & more
Certificates
Demo Cert per Domain under DOMAIN/security
keytool –list -storepass DemoIdentityKeyStorePassPhrase –v
-keystore DemoIdentity.jks
Certificate contains
hostname.
Unpack recreates Demo Cert
with hostname of new host.
21

22. munz & more
3 Simple Steps
1. Start Node Manager !
2. Create Machine!
3. Create Servers / Dynamic Cluster
and assign machine
Then use admin server web console to start
managed servers
22

23. munz & more
New in WLS 12.1.3"
Some nodemanager.properties names changed,
old names are deprecated now:
StartScriptEnabled
-> weblogic.StartScriptEnabled
also StartScriptName, JavaHome, StopScriptName,
UseMACBroadcast, …
23

24. #4 !
Server Templates
Server Templates

25. munz & more
Server Templates
st=create('myTemplateName','ServerTemplate')
MBean type ServerTemplate with name myTemplate has been created successfully.
st.setStartupTimeout(300)
25

26. munz & more
Examples
All managed servers should ...!
!
• have the same log level!
• have certain start up parameters
26

27. #5 !
Dynamic Cluster
Dynamic Cluster

28. munz & more
Dynamic Cluster
28

29. munz & more
How Dynamic Is It?
• Only configuration is dynamic!
• Must start servers manually
(dynamic runtime is still missing)!
• To decrease cluster size:
stop last server, then decrease
number of dynamic servers configuration
29

30. munz & more
What else you should know
Server Migration for dynamic and mixed cluster is
supported only with WLS 12.1.3!
!
-> Template based dynamic clusters are usually
easier than cloning a managed server
30

31. #6 !
Unicast Groups
Unicast Groups

32. munz & more
New Unicast Groups"
Implementation in WebLogic 12.1.3 changed:!
• Fixed max # of groups is 10!
• Groups can by asymmetric!
• Servers are consistently placed in groups based
on hash of server name
32

33. Classic Cluster Size 3
33

34. Dynamic Cluster Size 15
34

35. #7 !
Cluster Targeted JMS
Cluster Targeted JM

36. munz & more
Easier JMS
• Target JMS server to cluster
(also to dynamic cluster!)!
• Persistent stores are provisioned automatically !
• Then target distributed queue to JMS server
36

37. munz & more
Elastic JMS in WLS 12.1.3
• Supports whole server migration (WSM) with
WebLogic 12.1.3!
• Note, there are some restrictions:
No Unit-of-Order, no Unit-of-Work, no service
migration…

JMC and JDBC

39. munz & more
Java Mission Control
Java Mission Control comes
with JDK 1.7.0_40+
• Free for development !
• Ported over from JRockit!
• Detailed, graphical views!
-> start with jmc

40. Monitoring JDBC

41. munz & more
Java Mission Control
To enable JMC, you need the following switches!
JAVA_OPTIONS=” -XX:+UnlockCommercialFeatures
" " " " " -XX:+FlightRecorder"
e.g. configure settings in
DOMAIN_HOME/bin/setUserOverrides.sh
Configure
WebLogic
Domain-Wide
Settings here
