Can a single server instance (Ip Port combo) be part of two different clusters?

Hello,
          Is it possible for a single Weblogic 7.0 server instance to be a part of two different clusters?
          Thanks,

Migrating cProject and cFolder into a single server instance

Hi,
Has anyone had the experience to migrate cProjects and cFolderon seperated server instances into a single server instance? How data migration can be performed assuming cProjects server will be upgraded to 4.5 and the cFolders content will be ported over? is this something do-able? Or it is easier to upgrade cFolder first and migrate the cProjects data over?
Since documents link in cFolder/cProjects could be captured in transaction table, how to resolve it?
Would like to hear from anyone with such experiences... thank you.

Hi,
Is your new server Unix based? Are you planning to have 2 separate instances with separate DBs or are you planning to do a MCOD? Can you more details on what you mean by "2 in 1"?

Hey NON-TECHNO-WIZARD
You can do one of two things. The first is to just export out the contacts and import them into each other’s account. If something is updated the other person will not be updated with the information. Now another options is using one Apple ID for iCloud Syncing and then you can still use individual Apple ID’s for store purchases. The article below will shed some light on how you can use the Apple ID.

Can a SMB (server message block) be used as our file share in clustered OSB/SOA instance instead of a NAS?

We like to know if a SMB (server message block) will be adequate as our file share as opposed to a NAS. The SMB will be used for hosting files (e.g.: plan.xml, jms persistent stores, adapter control files, property files, binary files,...) that our services (OSB, SOA, Java) will be accessing in a cluster.
Also, is this a recommended approach that Oracle certifies?
Let me know if you need more details.
Current instance details:
OS: AIX 6.1
Type: 64-bit
WLS: 10.3.6

Hi,
As far as I know and as suggested by Mahdi, there is no such Group Policy settings which can help us to achieve this.
However, as also suggested by Mahdi, we can ask for help in the following scripting forum to see whether some scripts can help achieving this.
The Official Scripting Guys Forum
https://social.technet.microsoft.com/Forums/scriptcenter/en-US/home?forum=ITCG
If we can get such a script, we can use Group Policy to deploy the script to clients.

Can we keep two different clusters data in synch.

i have 10 coherence servers in newyork all forming clusterA and i do have 10 coherence servers in charlotte forming clusterB ,i wish to keep the data between cluster A and cluster B in synch.
Q1: is there any possible/configurable way to achive this.
Note: I dont want all the 20 coherence servers(newyork and charlotte) forming the same cluster.
Q2:Incase if all the 20 servers are forming the same cluster how would the read/write response times vary for the coherence clientapplications which are running in charlotte and newyork ,Asuuming i have 50 Apps running in charlotte and the same 50 apps(DR COPY) running in newyork.i am trying to achieve the best read/write performance.
Q3: is read/write performance vary only based on the cache type irrespective of network/location of coherence servers?
Thanks Much

How can I sync my documents on my devices if I have two different Apple IDs

I would like to be able to sync my Pages documents on all my devices. However, one of my devices uses a different Apple ID (my work one). Is there any way to get Pages to sync the documents created with the first ID onto the device with the second ID, or vice versa?
Thanks.

No, they have to be using the same iCloud account (ID) in order to use iCloud to sync them across your devices.

IDS 5.x: Is a separate configuration directory server instance even needed?

Because iDS 5.x supports multiple database instances, why is there a need to suggest installing the directory server with a separate configuration directory server instance (on say port 390)?
In large multi-tiered iDS 4.x directory server implementations, using a single master configuration directory server is very cumbersome, so many implementations are using a local configuration directory server instance, on port 390 with the data instance on the usual port 389.
With the iDS 5.x release, we will be implementing local directory server instances, all on port 389, on all of our tiered LDAP servers. There will be no separate configuration directory server instance, as it is not needed.
At this point, I am questioning the "best practices" suggested by the SunOne documentation to use a separate configuration directory server instance. It does not need to be on a separate port now with iDS 5.x supporting multiple databases.
And I note that the present "/usr/sbin/directoryserver setup" script will not allow for a directory instance to be installed on port 390.
Adam

Yes, with iDS 5.X, it's much safer to have the o=NetscapeRoot tree served by the same instance as your corp/user tree. The separation approach was created to avoid the pitfalls when importing LDIF, but the -n argument to ldif2db lets you avoid such problems.

Re: WLS51 multiple server instances - no clustering, no multihoming

Hello - This is the answer to a private question, but I'm posting it to the
group too in hope it will help.
Our problem was, we had one computer (Solaris) with one IP address and one
Weblogic license, but we had two (now three) teams of developers working on
different projects for WLS. Since they needed different settings and
configurations, they could not use a single Weblogic server instance, so we
had to find a way to run multiple server instances independently on a single
machine.
I'd call this configuration "parallel-servers" - please remember that it is
quite different from both multihoming and clustering because all the server
instances are independent from one another (unlike clustering) but run on
the same IP (unlike multihoming) and different port numbers.
This is the simplest procedure for a Solaris computer:
1: Install WebLogic.
Let's say the WL installation folder is:
/wls/weblogic/
we'll call that:
WL_HOME/WLS_HOME/
It contains the default server instance folder
/wls/weblogic/myserver/
we'll call that:
WL_HOME/WLS_HOME/myserver/
2: Make some copies (as many as you need)
of the default server instance folder
with different names, you'll have:
WL_HOME/WLS_HOME/myserver/
WL_HOME/WLS_HOME/server_1/
WL_HOME/WLS_HOME/server_2/
WL_HOME/WLS_HOME/server_n/
3: Locate the general properties file
/wls/weblogic/weblogic.properties
(we'll call it: WL_HOME/WLS_HOME/weblogic.properties)
and make a copy of it into EACH of the individual
server instance folders; you'll end up with:
WL_HOME/WLS_HOME/weblogic.properties
WL_HOME/WLS_HOME/myserver/weblogic.properties
WL_HOME/WLS_HOME/server_1/weblogic.properties
WL_HOME/WLS_HOME/server_2/weblogic.properties
WL_HOME/WLS_HOME/server_n/weblogic.properties
4: In EACH server instance's properties file
WL_HOME/WLS_HOME/server_i/weblogic.properties
set per-server values to all the properties
specific to the individual server; at least:
weblogic.system.listenPort=PORT_i
weblogic.password.system=PWD_i
weblogic.system.SSLListenPort=SSLPORT_i
plus everything else it should need individually,
that is, all the things that make that single
server instance different from all the others
(connection pools, ACLs, EJB auto deployments and so on)
Do NOT modify the file
WL_HOME/WLS_HOME/myserver/weblogic.properties
(it's a backup copy of the default settings)
5: In the GLOBAL properties file
WL_HOME/WLS_HOME/weblogic.properties
cancel or comment out all the properties
that have been individually set for all
the individual server instances; at least:
weblogic.system.listenPort
weblogic.password.system
weblogic.system.SSLListenPort
6: Locate the default server's startup script
/wls/weblogic/startWebLogic.sh
(we'll call it: WL_HOME/WLS_HOME/startWebLogic.sh)
and make a copy of it (in the same folder)
for EACH of the new individual server instances;
you'll end up with:
WL_HOME/WLS_HOME/startWebLogic.sh
WL_HOME/WLS_HOME/startServer_1.sh
WL_HOME/WLS_HOME/startServer_2.sh
WL_HOME/WLS_HOME/startServer_n.sh
7: In EACH server instance's startup script
WL_HOME/WLS_HOME/startServer_i.sh
set values to the properties:
weblogic.home=WL_HOME/WLS_HOME
(where WL libraries and global files are)
weblogic.system.home=WL_HOME/WLS_HOME
(where the GLOBAL weblogic.properties is)
weblogic.system.name=server_i
(where the PER-SERVER weblogic.properties is)
weblogic.system.listenPort=PORT_i
weblogic.system.SSLListenPort=SSLPORT_i
with the -D option, as in:
$JAVA $JAVA_OPTIONS -ms64m -mx64m -classpath
$JAVACLASSPATH -Dweblogic.class.path=$WEBLOGICCLASSPATH -Dweblogic.home=$WL_
HOME/$WLS_HOME -Dweblogic.system.home=$WL_HOME/$WLS_HOME -Dweblogic.system.n
ame=server_i -Djava.security.manager -Djava.security.policy=`pwd`/weblogic.
policy -Dweblogic.system.listenPort=PORT_i -Dweblogic.system.SSLListenPort=
SSLPORT_i weblogic.Server
8: If you like, you might also write a shutdown script
for each server instance (often faster than the console)
WL_HOME/WLS_HOME/stopServer_i.sh
which might look like:
java -classpath $JAVACLASSPATH weblogic.Admin t3://$HOSTNAME:PORT_i SHUTDOWN
system $PWD_i
9: If you need individual per-server security policies,
also duplicate and customize the default policy file
WL_HOME/WLS_HOME/weblogic.policy
(just like you did with weblogic.properties in steps 3 to 5)
and specify the corresponding property in each startup script
with the -D option
-Djava.security.policy=`pwd`/server_i/weblogic.policy
10: Obviously, when you deploy and use your EJBs or JSPs or applications,
you must make sure that you specify the right individual server's parameters
(name, user, password, port, paths and everything else).
And that's all; obviously, there are better ways to achieve the
"parallel-servers" configuration, but this is the simplest one and is good
enough for a basic development environment; you might need to tune some more
properties to suit your specific requirements.
On a WinNT computer, the procedure should be more or less the same, the main
difference being: instead of .sh script files, you'll have to edit .cmd
script files.
I am very grateful to all the people on the newsgroups who helped me work
that out. Good luck!

          You also need weblogic.system.name=server_n and I believe it's
          weblogic.system.home rather than weblogic.home. The latter should point
          to
          your /weblogic directory.
          Hope this helps.

11g Multiple Rpd on one BI server connecting to two different data marts

Hi
Did anyone tried and successfully implemented multiple rpds on one bi server. I have similar requirement in one of the clients place.
1. Install OBIEE 11g with vertical scaling( reason client doesnt want to spend extra money on additional server licenses) and would like to utilize the powerful existing servers.
2. Install 2 rpds on One BI Server and connect to two different datamarts.
3. Create two PS and provide two links to have two different reporting environments.
Appreciate with any pointers. I am very clear on Vertical Scaling and bumping up the Bi , PS and Java Hosts components. I saw a post with successful implementation of the same functionility in 10g and nothing in 11g. I already reviewed ritmanmeed blogs but did not give a complete picture of successfull implementation.
Thanks

Can i have the same application in two different oc4j containers?

Hi,
I have developed one J2EE application and still the updation is going on. So i wanted to to deploy the application in two different oc4j containers. so that one will be having the working version of my application and the users can use that application. I want to use the second container as my test application, in that i can modify and test. The deployment of my application in two different containers went fine. But when i try to access the web application with the context, it is serving from the latest deployment for my request.
My question is :
1) Can i use both applications with different Oracle HTTP server port numbers??
2) All the HTTP requests are passed to the oc4j containers by AJP13 protocol through AJP port to the OC4J containers. where is the mapping between the OHS and AJP protocol defined ??? ie., the requests from this http port have to be transferred by AJP protocol through AJP port to this OC4J container ???
3) Or i have to have two different installations of Oracle9iAS ???
Please help me to solve my issues...
Robert D

Different ohs port numbers would not help as there is only 1
$iashome/Apache/Apache/conf/mod_oc4j.conf
You can pick a different context_root name for your test app.

How can I edit a PE 12 project on two different computers?

I just installed Premiere Elements 12 on my Macbook Pro. I created a test project with several video clips. I then saved the project to an external drive to /Volumes/Media Library/Premiere Elements Projects. I then configured all scratch disks to point to /Volumes/Media Library/Premiere Elements Projects as well. I then used the Project Archiver utility to copy the project to this same directory.
I then installed PE on my iMac, and opened the project. After opening the project on my iMac, it complains that it cannot find related media files.
How can I configure PE so I can open and edit a project on an external drive, from two different computers?
-Thanks

I am PC-only, so there are probably several things that are specific to a Mac, that I do not know, but I do this on my laptop and workstation all the time - both PC's.
I set up an external HDD, so that it has the same drive letter in the OS of both computers. This is basically the same as the Mac Volume Name, but there are likely differences, that I do not know about.
Then, I create a folder structure for my Project, with sub-folders for all media assets. I then either Capture to those, or Copy my "stock Assets" from my NAS.
In PrE, I create New Project, in that Project folder structure, and then go to Edit>Preferences>Scratch Disks, and verify that all are set to Same As Project.
I edit on the laptop, until I need to migrate to the workstation. I plug in that external, turn it on, and it's seen as the same drive letter, as with my laptop. I open PrE, navigate to my Project folder on the external, and Open it - all media, and all Scratch Disk files are there, with the same exact Path.
Steve Grisetti, our MOD, uses both a PC and a Mac, so maybe he can talk about Volume Names, etc. on the Mac. I know that he does not migrate Projects to/from the PC and the Mac, as the PREL (Project) files are incompatible, but if he has two Macs, he'll be able to step you through Mac-specific issues.
Good luck,
