7. 12 things,
no agenda ☺

8. #0
... lots of changes

9. #1
OUI / opatch
opatch
for
WLS

10. 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
Docker
java –jar fmw12.1.3.0.0_wls.jar –silent
–responseFile fullPathToRespFile –invPtrLoc /etc/oraInst.loc
munz & more #10

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

12. Prerequisite Checks
munz & more #12

13. 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
munz & more #13

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

15. #2
Domain Wizard

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

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

18. #3
Per Domain
Node Manager
Per
Domain
NM

19. 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
munz & more #19

20. 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
munz & more #20

21. 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.
munz more #21

22. 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
munz more #22

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

24. #4
Server Templates
Server
Templates

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

26. Config Hierarchy
• Default Server Settings (value not specified)
• can be overwritten by
Server Template Settings
• can be overwritten by
Individual Server Configuration
munz more #26

27. #5
Dynamic Cluster
Dynamic
Cluster

28. Dynamic Cluster
munz more #28

29. 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
• Server Migration for dynamic and mixed
cluster supported with WLS 12.1.3
munz more #29

30. #6
Unicast Groups
Unicast
Groups

31. 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
munz more #31

32. Classic Cluster Size 3
#32

33. Dynamic Cluster Size 15
#33

34. #7
Cluster Targeted JMS
Cluster
Targeted
JMS

35. Easier JMS
• Target JMS server to cluster
(also to dynamic cluster!)
• Persistent stores are provisioned
automatically
• Then target distributed queue to JMS server
munz more #35

36. 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…

munz more #36

37. #8
Java Mission Control
JMC
and
JDBC

38. 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
munz more #38

39. Monitoring JDBC

40. 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
munz more #40

41. #9
WLDF Built-in
Modules

42. WLDF Diagnostic Module
WLDF Modules now easier: based on built-in
“Low” enabled by default in production mode
munz more #42

43. Predefined Watches (Medium)
munz more #43

44. #10
RESTful
Management
RESTful
Config
Part
I
/
Part
II

45. REST Management API
API has changed in WLS 12.1.3
- Supports configuration changes:
• Server lifecycle
• For resources, eg. JDBC data source:
create, stop, test, …,
• Deployments
munz more #45

46. REST Management API
Example http GET:
http://localhost:7001/
management/wls/
latest/deployments/
application
munz more #46

47. http OPTIONS with
/management/wls/latest
/datasources
returns the default JSON
structure for data sources
- Fill in the values and send
it back to server
Generate Template / OPTIONS
munz more #47

48. Create Data Source / POST
POST JSON data with all mandatory values to
/management/wls/latest/datasources
returns:
munz more #48

49. Limitations

libs
munz more #51

52. New Maven Goal
• 25 maven goals for WebLogic 12.1.3
• WebLogic 12.1.3:
New maven WLST goal: wlst-client
- does not require local WebLogic
installation for WLST online commands.
munz more #52

53. One more thing.

54. #12
Yes, Docker!
WLS
and
Docker

55. WebLogic
in

• NOT Now officially supported by Oracle
• Sandboxing based on Linux containers
• Layered images
• Public / private repository
• Containers start up in milliseconds
• Portable standard -
runs on Linux, also in clouds
