Multiple tomcat instances in one zone

I would like to install multiple tomcat instances in the same zone. the first instance starts without an issue. The second instance fails and gives an error message that it 'could not reserve enough space for object heap'. We are able to run multiple instances of tomcat on our solaris servers without a problem. Is there something I'm missing or is this a feature of zones? I've tried it in two separate zones with the same result.

Don't set the environment variable in your profile, that sets the env variable the same in every terminal session you launch. You need to set the WSHOME variable differently in each terminal depending on which instance you are working with.
I believe that should work.

How To Install Multiple OBIEE Instances On One Linux Machine

Hi,
OS: Red Hat ES 5.2
OBIEE : 10.1.3.4
We one development server(Linux) where one OBIEE 10.1.3.4 was installed with os user as 'ora1a' (Deployed on Oracle Application Server 10.1.3.4)
and now I have installed OBIEE 10.1.3.4 on same Linux Server with different user(ora2b) and different mount point (Deployed on Another Oracle Application Server 10.1.3.4 )
But My OBIEE was not working and I came to know that only one can be working by default.
After following few notes i have update NQSConfig.inc and odbc.ini with different ports ie from 9704 to 9725 and bounced BI server and presentation server
But still its not working can any one tell me what are all needs to update to make it work
Thanks in advance

Reference's i used: HOW TO: Install Multiple OBIEE Instances On One UNIX Machine (Doc ID 605582.1)

Hi
I was not much clear about what you are telling
See my first OBIEE instance URL is http://hostname18.oracle.com:7777/analytics (As i deployed OBIEE on Application server 10g(OAS1))
and second one is http://hostname18.oracle.com:7778/analytics (As i deployed OBIEE on another Application server 10g(OAS2))
Also My port for first OBIEE instance is 9704 and second one is 9725(Which i changed to this)
Now tell me what are all i should update

Multiple Tomcat instances on the same server

Can we have multiple tomcat instances load balanced on the same physical box without VM. Has there been any such implementations. How can CMS be distributed across. What can the know architecture for the same.
Regards
Vijsy

This can be done, but it really depends on the load balancer you use.
There is no recommendation from BusinessObjects and you might want to consult the load balancer vendor for instructions and support.

Multiple component instances for one component usage

Hi,all
How can I create multiple component instances for one component usage.
I'm using the following code for creating a single component instance for specific component usage:
if(c_Usage.hasActiveComponent())
c_Usage.deleteComponent();
if(wdContext.currentContextElement().getSelectedTab().equalsIgnoreCase("Registered"))
c_Usage.createComponent("health.gov.registered.Registered";);
I can't create one more component instance for
IWDComponentUsage c_Usage
cause I have to delete the component instance associated with this component usage.
Any idea how can I do it anyway?
Regards,
Michael

Hi,
To create another instance of the same component you need to embed the same component under the Used Components more then once. For Example if you have Componet A to which you want to embed Component B then under "Used Components" of Component A add component B twice.

Create multiple Task Instance from one Task Instance

We have a process, where user can request for multiple resources(access) in one single request.Currently user has to wait until all the resource requests are approved by application owners to start the provisioning process.
I am thinking of splitting that one request(task) into multiple task, based on the number of resources requested.so that, if one resource request is approved user can get that particular access.
My question :
1.How will I split the one task into multiple task and pass the required information to child task?
2.How do I handle views?Currently since its one task , we checkout and check-in the same view.
3.How will I overcome the possibility of one view overwritten by the other.
Thanks.

yes u can split one task into multiple task means as ur requirment diffrent task for different resource. so u have to write diffrent W/F for each resource and call them by setting a counter for number of resource.
the below code help u.

Multiple broker instances on one server

We are running multiple OpenMQ 4.4u1 broker instances on a single server (two different environments, one development and one staging). It appears as though the RC file I installed in /etc/init.d on our RHEL server is designed to manage one and only one broker instance (using the $IMQ_ETCHOME/imqbrokerd.conf file).
Is there an elegant way to have the single RC script manage multiple instances, or should I just create a second RC file and a second $IMQ_ETCHOME/imqbrokerd.conf file to manage the second instance?
Thanks,
Bill

Yes, the MQ RC script is for 1 broker instance only. On Solaris, it's possible to use SMF to manage multiple processes/services. You may want to look for something similar on RHEL or clone/customize the RC script, imqbrokerd.conf and relevant links in rc?.d for each instance

Multiple BW instances on one BO system

Hello experts,
The infrastructure setup of my project is to have 2 separate BW instances (testing and training) to be connected to the same BO system.
When setting up a BOJ connection (from Universe Designer), we need to specify the Application Server (ie. IP address of the BW instance). So it seems BOJ connection is BW instance-specific. However, we don't want to create separate sets of Connections (and hence, Universes & Queries) for each BW instance.
Is there any way for one Connection (and hence, Universe & Query) to be shared across 2 BW instances?
If this is not possible, is it possible to copy the Connection (plus Universe & Query) for BW instance #1 to a another Connection for BW instance #2? This is to simplify the effort of setting up BO for the second BW instance.
Thanks in advance for any suggestions.
Linda

Hi Ingo,
Thanks for the information. I too have same scenario to work out.
Is there any possibility of automatic Source/server name conversion from system A to System B while copying all the Universes and Queries.
For Example: In BI we have an option to datasource server name change convention while transporting from one system to another system through out the landscape.
As you said in your reply, in life cycle manager, do we need to edit connection for each & every universe or any option for one and all universes.
Any documentation on this is appreciable...
Please provide me information.
Thanks in Advance.

Ravi Kanth

Multiple database instance on one server

Hi experts
We are planning to implement ERP, BI, Solman, CRM and MDSD on windows/oracle platform. There is an idea about system landscape that all database instance of production systems are installed on one server and central instances of each system are installed on separate servers. Is there any performance or maintenance risk about this scenario? What is the advanteges and disadvantages of this landscape? Shall we prefer central system installation?
I'm waiting for your recommandation.
Best Regards...

Hi,
From experience one disadvantage in having an Oracle farm, is if the server plays up
or needs a reboot you of course lose all the systems databases.
Also getting all customers to aggree a maintenance slot together can be a pain.
Failover needs to be considered, DR also.
IMHO separate servers, but that is my preference I'm sure there are advantages.

Multiple Apex Instances for ONE listener

Hi All,
ENV:
1) Weblogic 10.3.5 hosting Apex Listener
2). Front END HTTP server for SSO
So... Apex request ---> HTTP SERVER AT Port 7777 ----> Apex Listener with weblogic.
So the question is:
1) is it possible to HOST another APEX INSTANCE on the SAME SERVER using this existing listener?
Sorry, if its vague , let me know.
thanks

Can I use multiple coherence instances on one JVM?

Or can I explicitly designate a tangosol-coherence-override.xml to coherence? If I can, how to?
Thanks.
Edited by: user8028833 on May 31, 2010 1:35 AM

OK apologies as I was going to just post the bits of code but I didn't get much time last night.
This code was originally written by a couple of us who wrote some security and single sign on code for Coherence. The project is on Google Code here: http://code.google.com/p/coherence-security/
The source is a Maven project so it follows the Maven directory structure. If you look in the coherence-security-core test sources there is a package called com.oracle.coherence.patterns.security.test.starter which contains all the ClassLoader code and classes to start a Coherence "cluster" in a single JVM.
The com.oracle.coherence.patterns.security.ApacheDirectoryTest test class uses this code to start a cluster to run its unit tests. To start the cluster you call CoherenceClusterStarter.getInstance() for example the com.oracle.coherence.patterns.security.ApacheDirectoryTest testSecureClientWithUnauthorisedCredentials() method.
    @Test
    public void testSecureClientWithUnauthorisedCredentials() throws Throwable {
        // Set the main class that runs to be the Secure servers
        System.setProperty("coherence.incubator.mainclass", SecureSandboxStarter.class.getName());
        // Make sure the cluster members run with the [email protected] Principal
        System.setProperty("sun.security.krb5.principal", "[email protected]");
        CoherenceClusterStarter.getInstance();
        // Run the client as the Thomas the Tank identity ([email protected]) which is
        // not authorised to connect as an Extend client in the extend-permissions.xml file
        System.setProperty("sun.security.krb5.principal", "[email protected]");
        LoginContext lc = new LoginContext("Coherence");
        lc.login();
        Subject subject = lc.getSubject();
        try {
            Subject.doAs(subject, new PrivilegedExceptionAction<Object>(){
                public Object run() throws Exception {
                    SystemPropertyLoader.loadEnvironment("client");
                    System.setProperty("tangosol.coherence.security", "true");
                    CacheFactory.getCache("test");
                    return null;
            fail("Expected to have a PortableException wrapping a java.lang.SecurityException thrown");
        } catch (PortableException e) {
            assertEquals("Portable(java.lang.SecurityException)", e.getName());
    }In the code above the first line sets the coherence.incubator.mainclass System property to the name of the class that will be run (in this case our secured DefaultCacheServer wrapper). Then the next line starts the psuedo-Cluster which the rest of the code uses.
Note
The Google Code above was originally done due to a requierment to secure Coherence using Active Directory (Kerberos). The code was started on 3.4 and eventually on 3.5.3 and then used to help Oracle change the Security API for 3.6. There are a few things not quite right and a few "gotchas" that are not in the code online.
Anyone is welcome to take it and use it but I and the others who worked on it offer no warranty or guarantee it will work for you.
As of Coherence 3.6 there are much simpler ways to do security - although if you want to use Active Directory or Kerberos some of the code on Google will still be useful.
Any problems or questions give me a shout either here or mail [email protected].

Dynamic memory allocation on HP-UX for multiple instances on one host

Hi everyone,
I was wondering what the current possibilities are nowadays on running multiple SAP instances on one very large host with regard to resource sharing. Normally, for each instance, using PHYS_MEMSIZE etc you have to set the memory to a fixed size and then optimize it.
Preferrably we would like the memory to be allocated based upon actual usage. Is that possible at all? on HP-UX? Using third party techniques?
Thank you
Marcel Rabe

Hello Marcel,
As Juan said you may not be able to change the parameters at runtime.
The only parameters that can be dynamically switched are :
ztta/roll_first
ztta/roll_extension
ztta/roll_area
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
em/stat_log_size_MB
em/stat_log_timeout
These parameters would put a cap on memory allocations, however they wouldn't help increase the total addressable memory area.
I would suggest that you consider Adaptive Computing for dynamic use of resources.

Can I have multiple TFS instances use a single SSRS installation

Can I have multiple TFS instances use a single SSRS installation?
Thanks

Hi Kim,
According to your description, you have multiple TFS instances using one Reporting Services instance. Right?
For installing TFS, to use a named instance with Team Foundation Server, you must install SQL Server by using a named instance, or move or restore Team Foundation Server data to a named instance, or create a team project collection on a named instance. Please
refer to the link below:

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.

One Oracle Application Server and multiple OC4J Instances

While we are getting new server (for development) we have to set-up a Development and Production enviroment for our project (dont have previous OAS installation) but on the same machine.
So, is a good option to have One OAS INstallation (Ora Home) and then create multiple OC4J instances, one for each environment (Development, QA and Production)?, is it possible? How to manage deployments between OC4J instances, simulating different contexts if they are in the same server and under the same HTTP Server? Will be there conflicts?

Hi,
you can do this and OracleAs will manage the different instances. The deployment can be done with Enterprise Manager in which case you select the OC4J instance first before deploying. If deploying from JDeveloper, you can specify the OC4J instance when creating the named connection
