Multiple App Server on a single host

I have a requirement to have multiple application server installations on a single server. Each installation will support a separate department. In the past each department had their own servers and had full control of their application server.
Would it be possible to create separate unix accounts for each department and install the Oracle Application Server under each separate account?
Will the installations be able to manage/avoid port conflicts? Or would I have to manage the ports manually?

Yes it is possible to have multiple instances of OAS (Oracle Application Server) in the same server, if the server hardware (especially RAM) can support it. The port numbers will be assigned automatically by the OUI (Oracle Universal Installer) for each new instance or you can specify them manually (you didnt say which version of OAS but there is a section in the matching installation guide.
However, consider this....
a) they are all still on the same server and any service interruptions to the server as a whole (e.g. apply patches, need to restart the server, all instances would need to be shut down)
b) These kinds of installations can be a horrible mess to administer
Personally I think a better solution is to separate the physical server using virtualization software e.g. VMware ESX to make separate virtual hosts. Then each virtual host has its own IP address and its own instance. e.g. host1 for department 1, host2 for department 2. Then each virtual host can be shut down, rebooted, patched etc, completely independent of the others.

Managing multiple Postfix instances on a single host

We have quite a few sites on our Xserve. Each site should be able to relay email out the respective unique IP on a single host; however, by default email goes out the default website of the server or which IP is the current gateway.
NOTE: this is not a Postfix Virtual Domain Hosting > mail forwarding domains issue. Mail routes just fine to the correct email boxes. This is and issue where email going out to other mail servers originates from the box and not the respective domains and IP space.
The solution for this is Multiple PostFix Instances. One for each website (each website has a respective IP due to SSL and DNS is correct along with MX records).
For the outbound mail relay for our corporate network it seems there are no fields to enable a new postfix instance for each hosted or virtually hosted domain. Nor is there a way to enable SMTP to relay outgoing mail through another host unless you use a generic setting for every website on the server.
So for a enterprise level business how do we Managing multiple Postfix instances on a single host?

Fully on the same page with you. 110%
Here is why I am under the impression of why each domain name needs to be as if it needs its own MTA (mail transfer agent). No matter how big or small the business.
Just like a domain using SSL in Apache needs a dedicated IP when doing the packets . . .
Yahoo the big dog (for small to medium online businesses 70% of their customers make purchases with Yahoo emails; which most of them are temp emails or known as aliases.) states:
From: help.yahoo.com/l/us/yahoo/mail/postmaster/basics/postmaster-02.html
Many mail providers follow the same guidelines:
{quote}Segregate your lists to different IP addresses. If you maintain several lists (or clients, especially for an ASP), you may want to segregate your lists to ensure that users are marking each list on its own merits. If user sees both spam and legitimate mail from the same IP, their notifications to us will be hazy and will likely result in the spam overiding the legitimate mail.{quote}
So why not segregate websites to email out their own dedicated IPs?
Understandably sites that share IP space can go out the default MTA or better yet the MTA of that IP.
This way host providers can segment groups of clients and further prevent issues with out going email.
When email goes out a single MTA there are checks and rate limitations not just on the hops involved but from the "originating" IP address. So if site "A" has one IP and site "B" has another . . . well they both send email out the same default gateway. Take 100's of domains going out the same IP and customers (websites) start having issues getting customer communications delivered.
{quote}Maintain accurate reverse-DNS information for your mail servers. Yahoo! Mail makes extensive DNS checks for each connection, and an accurate reverse DNS will ensure prompt processing of your connection and email.{quote}
One mistake by one client out of 1,000 sites (or now Apple letting tens of thousands of sites able to be hosted) can get all 1,000 websites deferred and have what is called "reputation" issues.
In the past, as companies grow, sure they get more boxes or can cluster mail servers. With economic times beyond using Parallels . . . a single Mac Xserve can handle tens of thousands of websites doing a few thousand emails a day or more. It is more of a software/setting/configuration issue than just capability.
I remember Intel board meetings in the 90's where I (as a customer) stated put two nic cards on the mother board, standardize those rails, put twisted pair on those hard drive cables. Some things just take practical experience to see yes there is a real need and the business people are not getting it because they are focussing on the business or chasing their tail.
Also Note the IP address has to be STATIC:
From: help.yahoo.com/l/us/yahoo/mail/postmaster/errors/550-bl21.html;ylt=AsNxnjlX971dwy743e7j.olJHdG
{quote}In our continuing efforts to protect our users from unsolicited email, Yahoo! Mail does not accept SMTP connections from dynamic or residential IP addresses . . .{quote}
From: help.yahoo.com/l/us/yahoo/mail/postmaster/basics/postmaster-15.html
{quote}Segregate your mail streams by IP addresses, domains and/or DKIM selectors since Yahoo! Mail keeps reputation data about each IP address and domain you send from. For example, by segmenting the mail stream that delivers marketing mail from another that sends transactional messages, you make it easier for Yahoo! Mail to determine and assign each mail stream's reputation. {quote}
{quote} Use common-sense settings. While we have not published guidelines for numbers of connections you can concurrently use, we ask that you treat our resources with respect. The more you take, the fewer there are for others, which may force us to defer your connections. {quote}
From: help.yahoo.com/l/us/yahoo/mail/postmaster//basics/postmaster-38.html
{quote}To facilitate the smooth flow of messages between legitimate senders and Yahoo! Mail, we offer the following recommendations:
Limit the messages you send per connection
Yahoo! Mail accepts a maximum of 5 messages per SMTP connection. We encourage you to cap the number of messages you send to Yahoo! Mail to fall within this per-connection limit.
When this limit is reached, no further messages will be accepted for delivery as our server automatically terminates the connection (without giving an error code). If you are sending messages to a significant number of Yahoo! Mail users, the suggestions below will help ensure uninterrupted delivery for your messages.
Reestablish connections if you do not get an error code
When our server terminates your connection after 5 messages have been accepted, you may try to reconnect to our MX servers immediately thereafter.
Open concurrent connections
You may open concurrent connections from the same server to facilitate efficient transmission of your messages. However, while we do not publish specific guidelines for the numbers of connections you can concurrently use, we ask that you treat our resources with respect. The more you take, the fewer there are for others, which may force us to deprioritize connections from your server(s).{quote}
In the Server Admin under General one can enable IMAP with a maximum number of connections. However, for normal SMTP there is no connections cap. Unless I am wrong here.
Domain throttling by domain is another way, but the real solution is just dedicated IPs for each website or each website to have a separate MTA. In the past this has meant a dedicated server or a physical gateway.
Technically there should be a Virtual solution. If I can virtually host many sites and many incoming emails on dedicated IP space respective to each domain. There should be virtual MTAs on dedicated or the same respective IP space as the incoming; hence, why I gave the example of how SSL works in Apache with web servers.
Totally get what you are saying on how currently mail works just out the default gateway since there is only one "default" MTA for the "xserve".
Everything is good coming in, but did something somewhere miss the mark on the outgoing? Should be one for one.
Yahoo is the big player putting the foot down or the glass half full people would say setting the mark on how outgoing mail should work when they are accepting emails.
I am not trying to innovate, but rather just follow the rules.
Sure mail out one MTA works no matter how many website you put on the box and it is "good enough for government work" or "looks good from my house".
There are many people struggling with corporate communications (even the concept of corporate communications and marketing) and I think Apple could step up to the plate and help follow the standard of best practices.
I have done research for 10 years and over the past two tested what I know to be true. Then spoke with many businesses that did not understand but had the same issue. . .
Yahoo customers not getting their email communications and email simply not being as good as the old fashion phone call.
So back to your question (fabulous question since every tech asks me the same thing):
{quote}So my question to you is this: why can't you run all your domains on a single server/IP address?{quote}
Because it is no longer 1996 and I want Apple stock to triple!
. . . and that it no longer works for sites conducting a profitable business. We are really underachieving what America could do!
Yahoo! is clearly saying to each business to do business communications or even marketing on separate IPs. Gmail, Hotmail, and the list goes on and on. They all follow the same thing. Yahoo! just happens to be more aggressive and has more good consumers (buyers) using their free email service. Gmail started aliases and could gain market share of buyers.
I need to get Xserve to have one dedicated IP in and out for each independent website whether it is an Apache transaction on port 80 (443 SSL) or an email going out the postfix MTA on port 25 SMTP or any other standard alternative port (587 or 465 SSL) for that matter.
So far everything works as expected, but the SMTP MTA out. One big default gateway per hardware.
We missed the 1% mark. That club that gets it! I would like to see every business owner that buys an Xserve to be in that one percent club out of the box!
Why Rob? Well because it works! Dedicated IPs work. Think about this, if you gave the postman your address and did not include your suite number more than likely your lucky if you get your mail. WORKS the same way for email.
If your business grows you can get a few more until something once again gets abused and they start tracking MAC addresses. By then will have virtual MAC addresses like most routers can already do.
To prevent SPAM you just set the MTA defaults to one IP per website. Let's keep it simple. This way you keep a clean reputation and one reputation per website or business. Most businesses just need one IP and cannot afford a whole server for each website/business. THINK GREEN!!! The email filtering systems (RBLs and filtering rules) already out there will weed abusers out. Let's not hurt the small to medium businesses in the process.
Your not going to get RDNS and dedicated IP space anyhow unless your a real business.

SP2013: Scaling search with multiple app server

Hi Team,
I am scaling a new SP environment with multiple App Server.
I have used AutoSPINstaller to install SP2013 and Search. My search components are spread across all servers. All Search components on all servers and I have a blank publishing site as part of my content source.
My issue is when i start full/Incremental crawl. It keeps on crawling for the whole day and do not produce any crawl error neither it stops. We waited for even 2 das but the crawl kept on going on.
Any help will be really appreciated.
Thanks Ba$va

Hi Basva ,
Follow these steps (one at the time) to reset the Content Source crawl:
Start -> Run -> Services.msc -> Restart the “SharePoint Server Search 15”.
Make sure the Application Server Administration Service Timer Job working .
Navigate to Central Administration-> Manage service application->
Search Service Application,
Reset Index and see if that fixes the problems.
Go into the Services.msc on each server and change the "RECOVERY" method of the “SharePoint Server Search 15” from "FIRST FAILURE" to "TAKE NO ACTION" so that the service did not restart before
all the servers had their "SharePoint Server Search 14" stopped.

Multiple XI instances or multiple app server

In a year or so we will be moving into an area where will be getting several feeds from several countries in Asia and South America. We now get feeds from EU and US.
The question most people are asking is whether we need multiple XI instances or multiple app servers. So there will nbe a need for 24/7 XI traffic which we already have now. What works best to support several time zones, backups, maintenances.
Would like to know how others are handling this in similar environment.
Thanks!

Hi pam,
> How would multiple app server help...meaning what's the most beneficial part of having multiple app server in such as scenario.
A good Question, benefit is lot, In simple words Load balance.. Performance in Transfering the messages will be quick, System resource is maintained and you can assign particular adapters for particular interfaces..alone... if you have Multiple App servers....

Got errors when trying to open word document with Office Web App Server and customized WOPI host

I am configuring the Office Web App Server with our ASP.NET MVC WOPI host based on this example. https://code.msdn.microsoft.com/office/Building-an-Office-Web-f98650d6. While both the OWA server and WOPI server has been set up and I can use Excel and PowerPoint
app to open and edit xls and ppt file now, there are problems opening word documents no matter I enable or disable the editing function of OWA server.
When I open a word document while enabling editing I got this error:
If I disable editing I got this message:
I have tried several file so I thought it is not the files' problem. Also I didn't find any exception in the log of OWA server.

Hi Gary Jiang,
Thanks for posting in MSDN forum.

Multiple Oracle 9ias instances on single host

hi all
i tried installing more than 1 instances on a single host, under different oracle home......but i am facing certaing strange errors. Can anyone tell me what are the things that we have to specifically take care of while installing multiple instances on single host, i mean any port issues or anything else??
please help
thanks

hi all,
i have almost the same prolem here.
i have created two instances other then OC4J home. i have also deployed two different applications on the two different instances. but when i try to run the application it gives Page not found exception! for both the applications.
now when i stop one instance then the other instance runs properly and doesnt throw any error!
there is definately no problem with the ports as internally the ports allocated to both the applications are different!
if anybody has got any idea what might be the problem then it will be very helpful for me!
thanks in advance!!

Is it possible to deploy multiple apps(ContextRoots) into a single stack?

Hi,
We want to deploy multiple Application Codes with different Context Roots to a single JavaStack using SDM. The purpose for it is to support our multiple Test environments(AIT, AFT, Prod Regression or etc.) using a single JavaStack environment. AIT will have AIT Context Root, AFT will have AFT Context Root and etc. Is it possible to do so? If so, how can we configure the SDM to support the deployment? We already know how to change the *.xml file for different context root.
Thanks

If the structure of the Excel sheets does not change from file to file then you can by having one ForEach Loop processing always the "Enrolled" sheet and another always the "Engaged" this is doable because the Excel OLEDB connector allows
to pick individual sheets, it is problematic therefore when sheet names themselves change.
MSDN has an example: https://msdn.microsoft.com/en-ca/library/ms345182.aspx

Multiple JVMs within app server - refresh of metdata not working

Hi guys.
We have an interesting scenario at present when running our application within a new test environment.
Our web-based application has the facility to refresh it's application metadata. This should mean that the next time the browser refreshes (or a user logs in to the application), the application will display based upon the refreshed metadata structure.
Previously, we have run our application on an app server with a single JVM without any dramas. ie. the refresh has always been reflected appropriately when viewing the application - as mentioned above.
However, we have installed the application in a new environment where the refreshing of meta data does not work consistently. That is, only about 50% of the time does the data refresh correctly. This can be seen by pressing the refresh button in an IE browser, so that the refreshed data appears approx. every second time the button is pressed. The only notable difference with this environment is that it runs 2 JVMs within the app server.
It seems that in this case, the 'old' data remains cached for the 'other' JVM, and that when the browser receives 'refreshed' data from the server, it does not always source from the same JVM.
This situation can be resolved by restarting the OC4J container, but this is not a desireable solution.
Is anyone aware of an OC4J parameter that can be set so that the 2 JVMs can run in synch so that both are refreshed appropriately when our meta data is cleared (refreshed) ? I don't believe this can be controlled within the Java source code, but I'm receptive to any other alternate solutions.
Thanks in advance.
Steve.

I'd like to embed multiple instances of the JVM within
a single, multi-threaded native server process. I'm
aware this was not possible with the Sun JDK in the
past.
Is this still true (for JDK 1.4.1 say)?Yes, this is still true.
If it's still not possible, are there any timetables
as of when it might be available? No.
Likelihood?Check the current list of JSRs at http://www.jcp.org.
Ah, btw: Is support for VM unloading (during
DestroyJavaVM()) available now?No.

In any case: does anybody know of a JVM
implementation
available for Linux which supports multiple VM
instances within a single process?Why do you need multiple VMs? Would multiple separate 'processes' within a single VM work? If so, have a look at:

Office web apps server (2013) certificate issue

If the name of the farm is different from the name of the individual office web apps server machine is there any way to deploy office web apps server with a single domain SSL certificate?
My office web apps server is working, but reporting itself unhealthy, apparently due to the fact that the SSL cert is for the name of the farm and that is different from the name of the machine.
Errors are 2004, 1004, 2156, 1156, "could not establish trust relationship for the SSL/TLS secure channel"
Going to the farm's discovery URL in the browser works fine, but going to the machine name (plus /hosting/discovery) gives an SSL error because the name of the farm is not the same as the name of the machine.
Is there any way to make it use the farm's URL instead of the machine's URL in its own internal watchdog operations? Or any way to make it use a self signed certificate on the machine's URL for it's own health checks and still use the legitimate purchased
SSL cert for user access? Or any other way you can think of to use a $5.99/yr single domain certificate instead of a $89.99/yr multiple domain certificate?
Bill Coulter

I am experiencing this same issue. The OWA server has sp1 installed. In the OWA event logs I am getting health fails for 2 events and as best I can tell it seems to be related to this issue.
We are also using a single godaddy certificate with a non machine name FQDN. Both internal and external url's of the OWA farm are set to this same name.
The problem only seems to occur with the 'Proofing Watchdog' (See events below).
Has anyone got any update on whether this is supposed to be fixed ?

Integration between EP & BW (with multiple application server)

Hello Experts,
We are configuring JCo Rfc Provider using visual administrator.
We have Successfully used Note No##Note 917950 - SAP NetWeaver 2004s:
Setting Up BEx Web,For Our Development & QAS BW & EP Server.(Single application Server)

We are not able to Specify the BW message server in the JCO Connection.
Kindly help us to resolve this issue.
With Regards,
Anshul

Hi Jim,
The reason that the documentation specifically spells out IBM Websphere is most likely because it was the application server that we developed and tested with at the time. The important requirement for this type of integration is that this server be an Intel based server running a Microsoft OS. The reason for this is because there are dlls with the Oracle IPM product that enable communication between the IPM functions and the JDE Business functions. If the Enterprise server for JDE is intel based then a JAS can exist on the same server, the dlls can be on that machine and the extra server is not required. This server is only required if the Enterprise server is not intel based. As far as your choice to use Oracle Application Server goes, I really have no basis to say if this works or not. My thought is that it shouldn't matter as long as the JAS server is an intel based, 32 bit server running a Microsoft OS. There are many other variables and lots of experience implementing this type of integration with JDE within the Oracle IPM consulting team. Give us a call if we can help.
Hope this helps,
Matt

How to create a single login for multiple apps on tomcat server?

Hello,
I am running the most recent versions of apache and tomcat on several dells with XP pro.
When I login to an app I have created, a session variable is set, but when I browse to one of the other apps on the same computer, it does not recognize that the session variable has been set and I have to login again.
Can somebody please suggest how, or where I can find docs, to configure tomcat to pass the session variables to other apps?
Thank you very much.
Or, can anybody suggest the most effective strategy for creating single-logon functionality for multiple apps with tomcat and apache running on one computer? and with tomcat and apache running on multiple computers? (i.e., each computer has tomcat and apache integrated).
The database is Oracle 10g running on each computer.
Thank you again.

A good place to start is http://www.javaworld.com/javaworld/javatips/jw-javatip34.html
Also, do a search in this forum on HttpURLConnection. That class allows you to use POST method to send form data to a web server.
"Hidden" variables are only hidden in HTML. The HTTP that gets POSTed to the web server doesn't distinguish between hidden and not hidden. That is, the content you would write to the HttpURLConnection.getOutputStream() would be something like:
hidden=1&submit=ok(Of course, the variable names would depend on what the web server was expecting from the form.)
Also, be sure to set the Content-Type request parameter to "application/x-www-form-urlencoded"

Does lion server support a single email address across multiple devices??

I am looking to move from an outdated Microsoft Exchange Server 2003 to OS X Lion Server but I am unsure as to how Lion will handle email. I do not want to spend money on a new windows server if I can get a Mac Mini Server to do the job. I am a very small business with a number of email accounts for a couple employees and need access to email and calendar from both the office iMac's and my Macbook Pro when on the road. My IT guy says I need Exchange but he's been off base on a few other items recently and I wanted to check with other sources.
I have 2 new iMac's, a MacBook Pro, an iPad1 and and iPhone4 on the mac side of things and 2 windows computers running XP. I would get rid of the windows computers completely if not for my CAD program which runs best not in a virtual machine mode.
How well will email and calendar entries sync across devices?

I have a very similar setup at my office. Lion Server will push email, calandar, contacts to all of your apple product with out a hitch.
As far the Windows XP machines, you can access email over IMAP with Thunderbird, and calandars via sunbird or the built in web app.
I would ditch the exchange server move to Mac OS X Server, and never look back.
God Luck!
PS. All of your devices will be in sync all the time.

Event ID: 1280 Server 2012 RDS - web app fail on second session host

Hello there
Topography
SBS 2011 (domain controller)
Two VM’s:
VM1 – All RDS rolls: RD Gateway , Connection broker, Licensing and RD access installed and acting as a session host with an active collection for RD web apps. A CA trusted certificate is installed.
VM2 – Session host with a second collection for RD web apps
Problem
I have a single app installed on both session hosts (the apps require their own servers). Both appear on the RDWeb site available for use. I can run the app hosted on VM1 no problem, but when I try to open the second app hosted on VM2 I get
two issues:
An error is returned
“Your computer can’t connect to the remote computer because the Remote Desktop Gateway server address and the certificate subject name do not match. Contact your network administrator for assistance".
When viewing the certificate, it actually shows the CA cert installed on the
SBS server for RWW, not the cert on VM1. This has me puzzled
Secondly on VM 2, I get
Event ID: 1280 Warning Microsoft Windows TerminalServcies-session broker client
Remote Desktop Services failed to join the Connection Broker on server sever-vm1.local.
Error: Current async message was dropped by async dispatcher, because there is a new message which will override the current one.
When I run the app internally it seems to load but then disappears.
Some further config info if it is relevant:
I have port 4043 (443 used) as the only port directed to the gateway
Am I missing something simple? DNS? Port forwarding issue on the router? Its my first deployment of this nature with RDS 2012
Regards
MIS5000

Hi,
Thank you for posting in Windows Server Forum.
Firstly please check the RDP version you are using. I suggest you to update to RDP 8.1 for better feature and functionality. Now other thing verify that you have the RD Gateway certificate name matches the external FQDN of the RD Gateway Server. Also please
check that certificate is added under local computer\personal store and must be signed by trusted root authority.
Please check below article for more detail.

http://blogs.msdn.com/b/rds/archive/2008/12/18/ts-gateway-certificates-part-iii-connection-time-issues-related-to-ts-gateway-certificates.aspx
In regards to resolve other issue (Event ID 1280), identify and fix any connectivity problems between the RD Session Host server and the RD Connection Broker by doing the following:
• Check network connectivity to the RD Connection Broker.
• Start the Remote Desktop Connection Broker service.
• Add the RD Session Host server to the Session Broker Computers group.

Having multiple Node manger process in a single host machine.

I am using weblogic server(portal)10.2.
I am running the Node Manager to start the admin server.I have installed Java based Node manager in the host machine .Created a unix id ND1 and started the Node Manager utiliy with this id.
I keep on creating domain for my new applicaitons and add this ND1 in each new domain group,so that ND1 will access the new domain's admin folder.
Now when I add this ND1 in more than 16 domain groups,I got trouble in accessing the domain folder.In unix OS there is group membership limitation where a unix id cannot be in more than 16 groups.
Anyone came acroos this issue?
Possible options.
1) Can we have multiple node manager ids(ND1,ND2,ND3..etc) for a single Node manager utility in single host?
2) While starting the server,will node manager look only the nm_password.properties file in domain folder?

You can boot multiple Node Managers if you change the NodeManager home. To do that, create a directory for each NodeManager and copy the startNodeManager script to it. Then edit the NODEMGR_HOME, LISTEN_ADDRESS, and LISTEN_PORT
