Number of 10gR2 instances on a single server

Good evening,
this is my first post here.
We want to create several 10gR2 instances (one per application) on a single linux server (Red Hat 4.0). We do not want to create one instance with separated tablespaces or schemas as the editors of the applications do not support it.
We would like to know how many CPUs we need per instance (in terms of fractional CPU and frequency).
We expect to have from 5 to 15 simultaneous users of these instances (rather OLTP work than decisional). Bigger ones have their own dedicated server.
Do Enterprise edition and Standard edition require the same CPU number/power ?
About multi-core CPUs, is the rule 1dual-core=1.5CPU correct ?
I thank you in advance for your help.

The amount of Oracle Instances you may create in the same box depends, mostly, on the amount of RAM available. You are required to properly configure the unix sempahores, otherwise, even if you have the required free memory, you won't be able to use it.
You have to spread your applications among several instances, but the usage profile is the same among them?, or stated otherwise, are the instances required to be configured just exactly the same? then you can easily estimate the amount of required memory per each instance and the estimated amount of memory required by the users.
Regarding the CPU there is not a thumb rule, you should gather usage statistics based on the current workload present in a typical instance on a typical day (cpu requirements constantly change for the same instance depending on the application usage), and build a baseline after the collected information.
Regarding the kernel parameters (semaphores), I suggest you to continue with this thread where I summarize the semaphore meaning and settings --> Re: Semaphores

Installing/Configuring multiple CMS instances in a single server machine

Hello,
We are installing BO enterprise server and we have a requirement which is as follows..
1. We have been given 1 server machine ( actual physical hardware machine )
2. We have been given two database repository instances ( one for Dev , other for QA )
3. We have to configure the 2 environments in the same server.
This means, Having two different CMS instances and pointing them to 2 different database repositories in one hardware server machine.
Any pointers how this can be achieved ?
I found a link where its mentioned that it can be achieved through the concept of SIA
[http://www.businessobjectstips.com/tips/server/business-objects-xi-3-xs-server-intelligence-agent-sia/]
But how do we achieve it?

First of all - this is not a good idea. It's possible to do, but not a good practice.
The purpose of QA environment is to Test what has been developed. If QA and DEV are on the same machine - what's the point?
Then your hardware server has to be big enough to support this.
I might be better to have 2 VM instances...
As to how to go about doing that :
1. It has been discussed here before, so if you search you'll see some good threads on the subject.
2. You'll need to review Admin guide and Install and Deployment Planing guides for the version of BO software you're going to use. (http://help.sap.com)
3. While pure BO stuff is fairly easy - you just create 2 SIA each pointing to its own DB and use different port ranges for both - you'll need to think about how to go about maintaining 2 instances of the Application server (Tomcat, WAS, WL etc ) to host 2 sets of BOE web apps (Infoview/CMC/dswsbobje)).

SAP ME - Can you use a single MSSQL instance on a single server?

Hi,
We need to build a demo system with the minimum of hardware so would like to use just one server.
The build would be Netweaver 7.4, ME 15 & MII 15 Using SQL 2012 as the database.
The question is, can I use a single instance of SQL or do I need to install two ? One for netweaver and one for ME ?
The ME database install guide states the following warning:
CAUTION
SAP ME does not use the same collation as the SAP NetWeaver database and server. Do
not use the SQL4SAP.vbs provided with MSSQL software to install the SQL Server database
software.
Does this mean I would install one instance for Netweaver using SQL4SAP.vbs and a second one (using a different port number) for ME using the standard installer ?
Or can I install just one database engine instance and configure the collation for each database individually ?
Also what about any of the other settings, eg Filestream and the XA install ?
Thanks for any guide that you can give.
Kevin

Hi Kevin,
We have this exact scenario on one of our internal sandboxes. Install a single SQLServer 2012 (we installed Enterprise version) instance and create the NW, ME WIP, ME ODS, and ME GODS databases separately, with different collations. We also have XA configured on the server, don't know about Filestream.
We are running a 2 CPU 8GB VM instance, I would recommend at least 12GB as 8 is minimal.

Installing a second HTML DB instance on a single server

I cloned a number of databases recently - they have all the HTML DB tables, workspaces, applications from the original database.
I modified the marvel.conf file to add some more DADs to point to the new instances.
I stopped and restarted the HTTP Server. (I did not touch the tnsnames.ora files)
When I tried to connect to the new instance with HTMLDB, I got the following error:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Oracle-HTTP-Server/1.3.28 Server at manlsidb01.thurnall.rts.int Port 7777
Where have I gone wrong?
A DAD entry:
          <Location /pls/exldev>
          SetHandler pls_handler
          Order deny,allow
          Allow from all
          AllowOverride None
          PlsqlDatabaseUsername HTMLDB_PUBLIC_USER
          PlsqlDatabasePassword @BXSdVR/chPb1lFpNSc8ePhy/9VAT4fm7qA==
          PlsqlDatabaseConnectString manlsidb01:1521:exldev ServiceNameFormat
          PlsqlDefaultPage htmldb
          PlsqlDocumentTablename wwv_flow_file_objects$
          PlsqlDocumentPath docs
          PlsqlDocumentProcedure wwv_flow_file_manager.process_download
          PlsqlAuthenticationMode Basic
          PlsqlNLSLanguage AMERICAN_AMERICA.WE8MSWIN1252
          </Location>

The problem was that the account had been locked when I cloned the database using Database Configuration Assistant - the log file showed up the error.
I unlocked the account, removed the password encoding and it worked fine.
It would still be nice to know how to encode the password. Will it be encoded if I create the DAD from the Oracle HTTP Server (Components) web page (as described in the Installation Guide in $ORACLEHOME\marvel\doc\installationguide.html)?
Thanks for your updates and for a great product!

Dual oracle instances on a single server

can a server run two different oracle instances which are two different
versions oracle?
That is,one instance in 7.3.4 and another in 8i!
first of all is it possible that we have 2
installations of oracle in
the same server??
pl advise.

Thanx for this reply.
Can you also please tell me as to what would be the sufficient system resources?
Masy be you can share your server config info if that's allright.
Regards,
Subbu
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Sam ():
Yes it's possible. I'm running 8.0.4 and 8.1.6 64-Bit versions on the same server. You have to change the environment variable when you log into svrmgrl to access the databases. Other than that it shouldn't be any problem. (Provided you have enough system resources)

How to config RAM of two instance sap on single server ???

I have a server (HDD: 146 Gb, 18 Gb RAM, RHEL 5.4 64bit, Oracle 10g R2), I used as system DEV and I have two questions:
Question 1: I want to install two instance SAP (SAP ECC 6.0 and BI 7.0) on this same server. I want to spend 9 Gb RAM for each SAP instance. So I have to configure how (Oracle instance is how much each instance SAP) ?
Question 2: Sap Application generally takes much RAM for each instance
Question 3: I need to install the package to install the SAP instance on RHEL 5.4 64 bit?
Question 4: What j2sdk package for 64-bit REHL 5.4 64bit?
thank for your advice

Multiple Instances of OEDQ on a single server

Hi,
I am running a Linux Machine (Linux 2.6.18-308.1.1.0.1.el5), on which I have the latest version of Oracle 11g release 2 installed.
I have an instance of oracle Enterprise Data Quality tool running on an apache-tomcat-7 server. Port 8080
Now I have a requirement of Installing another instance of OEDQ on the same server, but a different APACHE_HOME directory and a different Port Number (8081).
So the question is, Can we install multiple instances of OEDQ on a single server?
If so, what are the prerequisites to be maintained.
I did my bit of tries, but ended up having issues with some java errors.
I have posted the error message below.

Hi,
Multiple instances of EDQ on a single server is technically possible provided the installer takes care to avoid port conflicts. It is not the case that there is a single port used by an EDQ server, for example.
For various reasons, it is not officially supported; attempting to diagnose issues on custom installations on Tomcat is especially difficult and we do not provide documentation on this. In general, the requirement usually comes up for Dev/Test instances (as there is no performance advantage of using multiple instances on a single server), where we would recommend the use of virtualization where this is a requirement.

Mike

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"?

How to capture load of different OS users on a single server?

I am using Database version -11.1.0.7 64-bit , I have three different instances on a single server and therefore have 3 different OS users.
When I run Top command , it shows overall load.
Is there any way to capture load statistics user wise?

Connecting multiple ColdFusion 10 instances to a single Apache 2.2 server

This is replicated from StackOverflow's "Server Fault" site. The CF community there is under represented, so I'm posting here too. Sorry for "cross post".
This is on Windows 7 Home Premium edition.
I have got two ColdFusion 10 (updater 2) instances: "cfusion" (the default one), and "scratch".
I have got a single instance of Apache 2.2 running.
Within Apache, I have set up two virtual hosts, each of which needs to be served by a different ColdFusion instance.
Each of the CF instances serves files fine via Tomcat's internal web server. Apache serves vanilla HTML files fine too. So both CF instances, and both virtual hosts separately work OK.
I can get wsconfig.exe to connect either one of the CF instances to the Apache server, and serve CF files via Apache & that instance.
However I cannot find a way of connecting the second CF instance to Apache as well, so that both CF instances are conected, each serving one of the virtual hosts. WSConfig doesn't seem to understand the notion of "multiple CF instances", and the changes it makes to the httpd.conf (via mod_jk.conf) does not seem to be implemented in such a way as to accommodate multiple CF instances talking to a single Apache instance, or multiple virtual hosts. I freely admit to not being confident enough with how mod_jk (or even really httpd.conf) works to be able to guess if I can change stuff to make it work.
If I try to add the second CF instance using WSConfig, I just get a message "the web server is already configured for ColdFusion". Be that as it may... not the instance of ColdFusion I want to connect it to! If I remove the existing connector to whichever instance is already connected, I can then connect the other one no problems. Not that this helps, but it demonstrates that the CF instance can connect to Apache.
This all used to be fairly straight fwd under older versions of CF and JRun :-(
The only docs I have found are on the "Connect multiple Apache virtual hosts on a web server to a single ColdFusion server" page (http://help.adobe.com/en_US/ColdFusion/10.0/Admin/WSc3ff6d0ea77859461172e0811cbf364104-7fd 5.html), but that specifically only deals with a single CF instance. There is no equivalent page for multiple CF instances.
I'm kinda hoping I can move some of the mod_jk config into my virtual host entries in httpd-vhosts.conf (this is how it used to work for JRun), but I've no idea what to put where.
I think I've covered all the necessary info here? If not, sing out and I'll add more. Thanks.
Anyone? Cheers.

The answer to your question is Yes, a single mediator can invoke two service calls at same time as well.
First, define your service references in the composite.xml
Once you have done that, you can add any number of routing rules for each operation defined in the mediator. In your case, you will need to add two static routing rules within the same operation in the Mediator file. You can also select whether the calls will be sequential or parallel by selecting correct value in the dropdown inside the routing rule. Each routing rule will invoke one service reference in your case.

Hosting two portals on a single instance of enterprise portal server

Hi,
We have a requirement to host two different portals on a single instance of enterprise portal server. The URLs to the portals would be different. Also for logging into the portal, one portal would have only User ID and Password and
the other may have Retailer ID, User ID and Password for logging.
I am trying to understand what kind of an approach needs to be followed. There
is a single instance of Oracle server where PCD is stored.
How will authentication/authorization happen and how would the user data be stored for both the portals in a single instance of Oracle database.
Thanking you in advance,
Regards,
Veena

Hi,
in general, could do that by using a distinct role concept. With the "Collection of base rules" you can assign different portal desktops with different layouts to everyone based on criterias like groups, roles or users.
We have 4 very different portals running inside one instance. Every portal has its own standardized structure and is selected by logon groups, that points to roles, which points to desktops.
What will not work is a logon concept other than "userid, password". SAP, by default. only allows standard authentication with userid and password or ticket. Even if you use an LDAP that would have that distinction, you cannot query that property without modifying the system
If you want to use anything different, you have to write a new logon handler for the logon stack (using JAAS). This is tricky, but not outrageous difficult. We have implemented three different new steps in the logion stack, each handles a different case, from ip-based logon, ticket or LDAP query. It is possibly, all of them don't have more than 20 lines of java.
But, still tricky.
It is a broad theme and you can try it out with showcasing two different desktop themes belonging to two different roles. Than you can work your way through tge problems.
In terms of database, it makes no distinction. You work solely with the PCD, and that is stored in the database. We are using DB2 and I've never touched the DB at all.

Maximum number of Oracle-10/11 instances on a Windows server?

Hi,
What is the maximum number of oracle 10/11 database instances that can be installed on a Windows-32 server.
Also what is advisable?
Assuming each database instance will have no more than 4 concurrent users with light usage.
Windows Server - 2008 4GB Ram Xeon or similar processor.
Many Thanks

You can have any number of instances installed on the server. 42 is a great number.
Just don't turn on more than one or two instances at a time.
Better might be to look at, and understand, 'schema' concept - it may be possible to use multiple schemas in one instance/database to accomplish the same thing as your multiple instance proposal.

Multiple SAP instance on single server.

Hello Experts.
We are in process of implementaing SAP solution withLandscpe having systems ECC 6.0, SolMan 4.0, BI. We are planning to have 3 Sytem landscape for all.
Now but currently we are having only one Physical server
Is it possible to Install 6 SAP system on single server?(DEV and QAS for ECC, Solman, BI respectively). The server is having sufficient hardware for 6 system as per sap standered. Planne OS is RHEL and DB MaxDB. Initially we are having 16 GB RAM extendable.
Will SAP support such kind of landscape?

Hello,
We did not put 6 systems on the same server but we are running fine with 4 systems (R/3, XI, BI) on one server (8 itanium, 32 GB ram).
16 GB seems very small for 6 systems...
Don't forget that beside the obvioous economy, they are also big cons with mutualization.
When the server crashes because of a hardware failure, all of your landscape is out and the phone rings a lot.
When you need a reboot for one system, you have to stop all the others...
Good luck !

Olivier

How Can I Use Multiple Weblogic Instances in a Single OS

Hello Everyone,
Actually I have to install Some different applications. Few of them need weblogic 10.3.6 and others need 10.3.4. The OS am using is Oracle Enterprise Linux 5.
Now I am able to install 2 separate(One of 10.3.4 and 10.3.6) instances with two different users,In two different directories.
I have installed the weblogic 10.3.6 version with a user webadmin and installed node manager with port 5556. This is working fine.
The main problem here is :
In the second instance (10.3.4 ) installed with a a different user and gave the port number to NodeManager as 1600 and its not getting started. Its throwing error and also after some errors in the terminal am able to see that its reverting to port number 5556 only.
What might be the issue?
I have to install 2 different versions of weblogic in a single Server. But am failing with NodeManager. What Can I do to have multiple weblogic instances with multiple versions in a single server ?
Can anyone suggest a resolution for this please ?
Thanks in advance.

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?

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:

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:

{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}

{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.
