Do I need to run sapinst at Oracle Server?
Hi,
I am installing an EP SP2 with Oracle. The database already exists in another machine and now I am trying to install the portal schemas at Oracle.
Do I have to run sapinst at Oracle Server or the portal database installation could run remotely at EP Server?
I had Oracle client and tnsnames configured at Portal server and I already connected to Oracle server using sqlplus...
Thanks.
you should run SAPINST on the ORACLE host and select install DB SCHEMA. After finished, you run SAPINST on other hosts for install PORTAL/CM/COL...
wish this can help you.

Do I need to run DNS on a colo server being accessed remotely via VPN?
My Mac Mini Server is located in a colo site. We generally use it for Web, email and a couple of application-specific services. It has a dedicated IP address. We have a separate DNS service we use to point to the domains on the server located remotely from the server. Forward and reverse lookups work fine from the server, even though the local DNS service is turned off.
However, we now have a couple of things we want to access remotely on the server via VPN (for example, some files via AFP). The firewall blocks remote AFP requests (using the built-in firewall, not a separate box). We can connect via VPN without problems. However, AFP does not work. If I allow AFP in the firewall and try to connect, no problems at all.
Since the Mini is located by itself and will never likely have anything connected to a "local network" (never running DHCP, etc.), there generally doesn't seem to be a need to run DNS on the server.
I suspect the problem is that when you VPN into the server you are on its "local network", whatever that means, so the DNS does not resolve since the local DNS service is not running. However, I am not positive of this.
Must we run local DNS? Does it have to mirror the remote DNS that we currently reference? Can we somehow "reference" the local DNS from VPN clients trying to access local services?
I hope this question makes some sense.Bear with me please....
The Mac Mini is in a data center on a shelf, getting a direct connection to the Internet via ethernet with a fixed IP address (under the covers, I suspect that the data center is using some sort of router or switch, but I am not paying for a hardware firewall or other gateway). There is no local network for the Mini. It is not running DHCP, not handing out NAT addresses, etc. DNS is currently off. Rather than using the local DNS, the Mini is resolving its DNS needs with a DNS server located at another site, over the Internet. This seems to work fine (i.e., changeip confirms it is working and services seem to work).
I am currently using the software firewall built into SLS.
I want to turn on VPN so that remotely located computers can access services on the Mini without having to make the services visible through the firewall.
I am able to connect devices via VPN with little difficulty (iPhones, Macs, etc.). However, when I try to access services (let's use AFP as an example), I cannot access them UNLESS they are allowed through the firewall. This tells me that I am not seeing the services through the VPN, but rather through the Internet directly.
What I meant by "local network" is that the VPN allocates local IP addresses when devices log into the VPN service (10.0.x.x). There is no DHCP allocating these addresses, just VPN.
My question is: why can I not see the services on the Mini blocked by the firewall when successfully logged into VPN on the server? Isn't the whole point of the VPN to gain access to services behind the firewall?
I am guessing (with no particular information to support my thesis) that somehow without DNS running on the Mini, VPN clients are unable to access services on the Mini. I do not know for sure, however, if this is the problem. If it IS a problem, then the question is whether I should completely copy the DNS entries from the remote DNS server to the Mini and start the service. Will that solve the issue? Create conflicts with the DNS (since it is now located on both a remote service and on the Mini)? It certainly will create a maintenance headache since now I will have to maintain the DNS in both places.
I am hesitant to migrate all of my DNS services to the Mini (because I will also have to go to the domain registrars to change where they point, etc.) to eliminate the remote one. And I am not sure it will solve this problem anyway.

Transaction Processing Monitors (TPMs). The topics covered in this article are

Explanation & Example
What is a Transaction Processing Monitor?
=========================================
Under UNIX, a Transaction Processing Monitor (TPM) is a tool that coordinates
the flow of transaction requests between front-end client processes that issue
requests and back-end servers that process them. A TPM is used as
the "glue" to coordinate transactions that require the services of several
different types of back-end processes, such as application servers and
resource managers, possibly distributed over a network.
In a typical TPM environment, front-end client processes perform screen
handling and ask for services from back-end server processes via calls to the
TPM. The TPM then routes the requests to the appropriate back-end server
process or server processes, wherever they are located on the network. Through
configuration information, the TPM knows what services are available and where
they are located. Generally, the back-end server processes are specialized so
that each one handles one type of requested service. The TPM provides
location transparency as well and can send messages through the network
utilizing lower-level transport services such as TCP/IP or OSF DCE.
The back-end servers process the requests as necessary and
return the results back to the TP monitor. The TP monitor then routes
these results back to the original front-end client process.
A TPM is instrumental in the implementation of truly distributed processing.
Front-end clients and back-end processes have no knowledge of each
other. They operate as separate entities, and it is this concept that provides
flexibility in application development. Front-end and back-end processes are
developed in the UNIX client-server style, with each side optimized for its
particular task. Server functionality can be deployed in stages, which makes
it easy to add functionality as needed later in the product cycle. It also
makes it easy to distribute both the front-end and back-end processes
throughout the network on the most appropriate hardware for the job. In
addition, multiple back-end server processes of the same type might be
activated to handle increasing numbers of users.
What is the X/Open Distributed Transaction Processing Model?
============================================================
The X/Open Transaction Processing working group has been working
for several years to establish a standard architecture to implement
distributed transaction processing on open systems. In late 1991,
X/Open published the initial Distributed Transaction Processing (DTP)
model specification and defined the first of several interfaces that
exist between the components of the model. Subsequently, other publications
and a revised model specification have been published.
An important function of the TPM in the X/Open DTP model is the
synchronization of any commits and rollbacks that are required to complete
a distributed transaction request. The Transaction Manager (TM) portion
of the TPM is the entity responsible for ordering when distributed commits
and rollbacks will take place. Thus, if a distributed application program
is written to take advantage of the TM portion of the TPM, then it,
and not the DBMS, becomes responsible for enabling the two-phase commit
process. Article 2 has more detail on this model.
How does the Oracle Server work with TPMs?
==========================================
When a TPM is used without invoking an X/Open TM component to manage the
transactions, Oracle Server needs no special functionality. The transaction
will be managed by Oracle itself. However, when the TPM X/Open TM component
is used to manage the transaction, the Oracle Server, that is the Oracle DBMS,
acts as a Resource Manager--a type of back-end process. In the case of
TPM-managed transactions, the TM needs a way to tell the RMs about the stages
of the transaction. This is done by a standard, X/Open defined interface
called XA. Article 2 of of this document gives more information about both
the X/Open model and Oracle7's use of XA.
Because the XA interface provides a standard interface between the TM and the
resource manager, it follows that the TM can communicate with any XA-compliant
resource manager (e.g., RDBMS), and, conversely, that a resource manager can
communicate with any XA-compliant TM. Thus, the Oracle Server, beginning with
Oracle7, works with any XA-compliant TM.
How should I position TPMs with my customer?
============================================
There's been a great deal of confusion about the need for TPM technology. Some
software suppliers, most notably IBM, will assert that a TPM like CICS is a
necessary requirement for high volume OLTP. Other vendors will assert that
there is seldom a need for such technology. And yet others promote TPMs as
providers of higher transaction throughput.
From Oracle's standpoint, customers might choose TPM technology under any of
the following conditions:
1. For heterogeneous database access, especially for 2PC capability
This means that a TPM can be used to coordinate 2PC between Oracle
DBMS and any other XA-compliant database, such as Informix. This
does NOT provide SQL heterogeneity - SQL calls to Oracle DBMS may be
different than SQL calls to Informix. The TPM handles the routing,
communication, and two-phase commit portion of the transaction, but
does not translate one type of SQL call into another.
2. For transaction monitoring and workload control
The leading TPMs supply tools to actively manage the flow of
transactions between clients and servers and to load balance the work
load across all available processors on a network, not just on a
single multi-processor system. Some TPMs also have the ability to
dynamically bring up additional back-end services during peak work
hours.
3. For more flexible application development and installation
One of the key features of the DTP model is application modularity.
Modularity, that is, the decomposition of a large program into small,
easily defined, coded and maintained "mini-programs" makes it easy to
add new functionality as needed. Modularity also makes it much easier
to distribute the front-end and back-end processes and the resource
managers across hardware throughout a network.
4. For isolating the client from details of the data model
By using the service oriented programming model, the client program
is unaware of the data model. The service can be recoded to use a
different one with no change to the client. To get this advantage,
the application developer must explicitly code the server and client
to fit the service model.
5. For connection of thousands of users
TP Monitors, because of their three-tier architecture, can be used
to connect users to an intermediate machine or machines, removing
the overhead of handling terminal connections from the machine
actually running the database. See Article 4 for more information.
There are also several cases where TPM technology is not the right answer.
These include:
1. If the customer is simply looking for a performance improvement
The customer may have heard a theory that "higher performance
is possible for large scale applications only if they use a
TP monitor". First, no performance gain can be achieved for
existing applications; in fact, they won't even run under a TP
Monitor without recoding. Second, performance improvements have
only been documented for large numbers of users, and "large"
means many hundreds or thousands. Without a TP Monitor,
Oracle Server can handle several hundred users with its normal
two-task architecture and several times that using the Multi
Threaded Server. For more on performance, see Article 4.
2. If the customer has made large investment in his existing Oracle
applications
TP monitor applications must be designed from the ground up to take
advantage of TP monitor technology. Current Oracle customers will find
it difficult to "retrofit" a TP monitor to their existing applications.
The Multi Threaded Server, on the other hand, allows the use of
existing Oracle applications without change.
3. If the customer is committed to the Oracle tool set
Currently, none of Oracle's front-end tools (Oracle Forms, etc.) is
designed to work with TP monitors. It is possible to invoke a
TP Monitor by using user exits. However, the fact that the TP
Monitor model hides the data model from the client means that only
the screen display parts of Forms can be used, not the automatic
mapping from screen blocks to tables.
4. If the customer does not have a staff of experienced software engineers
This is still very young technology for UNIX. There is not a lot of
knowledge in the industry on how to build TP monitor applications or
what techniques are most useful and which are not. Furthermore,
integrating products from different vendors, even with the support
of standard interfaces, is more complex than deploying an integrated
all-Oracle solution. Because TP monitor technology is fairly
complex, we recommend that you let the TP monitor supplier promote
the virtues of their technology and differentiate themselves from
their competitors.
What Oracle products must a customer purchase?
==============================================
If your customer is only interested in building Oracle-managed TP Monitor
transactions, the only Oracle products required are the Oracle Server
and the appropriate Oracle precompiler for whatever language the
application is being written in--most likely C or Cobol. If TPM-managed
transactions are required, the Oracle7 Server with the distributed option
is also required. SQL*Net is optional because the TPM takes care of the
network services. Article 2 describes when you would choose to have the TP
Monitor manage the transactions.
Where can my customer purchase a TPM?
=====================================
There are many vendors offering the UNIX TPM products. (Oracle does not
relicense TPMs.) Information on the most well known products is provided
below:
The following support XA:

In addition, Groupe Bull, Digital, Siemens-Nixdorf, and several other hardware
vendors are planning to redesign their proprietary TPMs to be XA-compliant and
suitable for use on UNIX systems.
Availability and Packaging
==========================
On what platforms is the XA Library available?
Oracle provides the XA interface with Oracle7 Server on all platforms that
support an XA-compliant TPM. Support for XA is included as part of the
Oracle7 Server distributed option and has no extra charge in and of itself.
Which version of XA does Oracle Server support?
Oracle7 Server supports the Common Application Environment (CAE) version of
XA, based on the specification published by X/Open in late 1991. It will
require that the TM also be at that level. This means Tuxedo /T version 4.2,
for example.
Oracle Server supports all required XA functions. There are some optional
features Oracle Server does not support, such as asynchronous operation.
None of those options affect application programming.

Oracle Server Working with UNIX TP Monitors
===========================================
Do I need XA to use Oracle Server with TPMs? If I don't use it, what are
the consequences?
There are a number of real applications running today with Oracle Server and
TPMs but not using XA. To use a TPM with Oracle without using XA, the user
would write an "application server" program which could handle one or more
"services". For example, a server program might handle a service called
"debit_credit". The key requirement is that the entire transaction,
including the "commit work", must be executed within a single service. This
is the restriction which XA will remove, as we'll see later. Each
server process can serially handle requests on behalf of different clients.
Because a server process can handle many client processes, this can
reduce the total number of active processes on the server system,
thereby reducing resource requirements and possibly increasing overall
throughput.
When Oracle is used with a TPM in this mode, we call it an Oracle-managed
transaction since the transaction commit or rollback is done with a SQL
statement.
What is XA? How does XA help Oracle7 work with UNIX TPMs?
XA is an industry standard interface between a Transaction Manager and a
Resource Manager. A Resource Manager (RM) is an agent which
controls a shared, recoverable resource; such a resource can be
returned to a consistent state after a failure. For example, Oracle7 Server
is an RM and uses its redo log and undo segments to be able to do this.
A Transaction Manager (TM) manages a transaction including the
commitment protocol and, when necessary, the recovery after a failure.
Normally, Oracle Server acts as its own TM and manages its own commitment
and recovery. However, using a standards-based TM allows Oracle7 to
cooperate with other heterogeneous RMs in a single transaction.
The commonly used TPMs include a TM component for this purpose. In order to
use the TM capability of the TPM rather than Oracle7's own transaction
management, the application uses a transaction demarcation API (called TX)
provided by the TPM rather than the SQL transaction control statements (e.g.
"commit work"). For each TX call, the TM then instructs all RMs, by the
appropriate XA commands, to follow the two-phase commit protocol. We
call this a TPM-managed transaction.
The following picture shows these interfaces within a monolithic application
program model. This is the model most commonly described in the
DTP literature. We'll see later what the picture looks like when we add
Oracle7 and when we switch to a modularized client-server application
program model.

| (RMs) | |<-------->| (TM) |
| |--- | |
| |<----------->| |
---------------------- XA --------------------
Interface
The XA interface is an interface between two system components, not
an application program interface; the application program does
not write XA calls nor need to know the details of this interface.
The TM cannot do transaction coordination without the assistance of
the RM; the XA interface is used to get that assistance.
How does the DTP Model support client-server?
The above picture was actually simplified to make it easier to explain
the role of XA. In a true distributed transaction architecture, there
are multiple applications, each with an Application Program, a Resource
Manager, and a Transaction Manager. The applications communicate by
using a Communication Resource Manager. The CRM is generally provided
as a component of the TPM. It includes the transaction information when
it sends messages between applications, so that both applications can
act of behalf of the same transaction. The following picture
illustrates this:
Client Application
| AP |
||| | |
SQL ||| | TX | CRM
||V V | API
-||-- ----- |
| |V | | | V
--|-- |<---| | -----

| | || | |XA+ | |
| | RMs |<-----| | -----
| | | XA | | A
| ----- ----- |
| |
| |
-------- |
/ |
/ |
/ |
Most TP Monitor products include both a TM and a CRM, and also provide
additional functions such as task scheduling and workload monitoring.
What is XA+? What does Oracle need to do to comply with it?
XA+ is an interface that lets the X/Open model actually be distributed
because it allows a communication resource manager to tell a TM on the
server that a message from a client just came in for a particular
transaction. Oracle is not currently planning to provide an X/Open
communication resource manager, so we don't have any plans right now
to do XA+. Version 2 of the DTP model paper from X/Open describes it.
The status of the current XA+ specification is "snapshot".
When would I choose an Oracle-managed transaction vs a TPM-managed
transaction?
Oracle Server is very efficient at managing its own transactions. If
the TPM manages the transaction, in general some additional overhead
will be incurred.
The two main reasons a customer might prefer to use a TPM-managed
transaction are as follows:
(1) He may need to update RMs from different vendors. Experience so far
has been that the most common case is wanting to update both Oracle and
a TP Monitor managed resource such as a transactional queuing service
in the same transaction (see Article 3).
(2) He may want to use the model of having several different services in
a transaction, even to the same database. For example, the
"debit_credit" service could be split into a "debit" service and a
"credit" service. This is a very attractive model, but this type of
modularity does exact a performance penalty (see Article 4).
Can I get a version of XA to run on Oracle Server version 6?
No, the XA functionality uses two underlying mechanisms in the Oracle
Server which are not available in version 6: two-phase commit and
session switching. The upi calls for these functions do not not exist
in version 6.
When would I use XA vs Oracle7 to coordinate all-Oracle distributed
transactions?
Generally speaking, Oracle Server should be used to coordinate all-Oracle
distributed transactions. The main reason for using XA to coordinate
transactions would be that you want to use the TP Monitor service-oriented
architecture. That is, you would like to construct an application built of
services and service requests in order to benefit from the modularity and
workload control such an environment provides.
TP Monitor Application Architecture
===================================
What might a TP Monitor application look like?
Most TPM applications will consist of two more more programs, where
there are front-end client programs which request services and back-end
server programs which provide services. In this case, the TPM supplies an
additional capability which is transactional communication. The client
describes the boundaries of the transaction, through the use of the TX API,
and the TPM relays that transaction information to each requested service.
The overall application structure generally looks like the following in the
client-server model. The "TP Monitor Services" box is not necessarily a
process. It could be one or more processes, or just libraries coordinating
through shared memory. Each client process and server process could be on
a different machine. Normally, the application server processes would be
connected to their Oracle Server processes using the IPC driver; the TPM
would be used to deliver messages between application client processes on
one machine and application server processes on another. However, the
application server processes could also be connected with the standard
Oracle SQL*Net to shadow processes on different machines. This might be
useful if one of the databases was on a machine which did not support TPMs.

Application client programs might be written in C and be linked with
TPM libraries. Alternatively, they could use a screen painter product.
Application server programs would be written in Pro*C or Pro*COBOL and
be linked with TPM libraries, the normal Oracle7 user-side libraries
and libxa.a. The Oracle7 Server process is the regular Oracle7 executable.
More complicated application architectures can also be constructed. Most of
the TPMs allow a server to become a client of another service, so you can
involve additional servers.
Could I use Oracle7's Multi Threaded Server as the SQL*Net connection in the
previous picture?
Yes, but that will not be needed in many cases. For example, both
application server processes in the previous picture could talk to a
single Oracle7 Server process through the Multi Threaded Server in the
previous picture. However, since the TPM architecture typically reduces
the number of server processes, the reduction in processes using Multi
Threaded Server may be less significant than in an architecture without
TPMs. If the application will use database links, however, then MTS will
be required.
How do I write an Oracle TP Monitor application?
The actual API used to talk to the TPM varies between vendors, so you need
to get the documentation from the vendor. However, all have a way to
indicate where a transaction begins and ends and a way to send a request
and receive a response from a client to a server. Some use an RPC model,
some use a pseudo-RPC model, and some use a send/receive model. The TX API
described earlier is a subset of the TPM API as defined by each of
the TPM providers.
The client program and server program might look something like the
following examples. We h (such as Tuxedo's

Help go count hardware for oracle server
Hi,
I need to count hardware for Oracle server;
users obout 10000 people at the same time.
What memory(RAM) and proceesos frequens(MHz) should be?
Where to find information about it?You should consider that if 10000 users will be concurrently in the database, and if at least 2m ram will be consumed by an oracle server process (just to start), then 20000mb ram will be required (at least) to support 10,000 oracle processes at the same time, about 20Gb for users, next, consider the amount of required SGA memory (not an exact value, as it depends on the database profile, DWH, OLTP, Hybrid). plus the processes for the regular OS operation.
This is not a small application, have you thought about growth? You should be thinking about scaleability. May be not a huge machine, but a cluster of more affordable machines that will grow with your needs. -

Need to run "clearfault" on M5000
I have a customer that has an M5000 <b>not</b> under maintenance with Oracle. They have a fault condition on the frame and they need to run "clearfault" to clear the condition. Will Oracle supply the special password without a contract?
Bob,
See if your customer can open a support call on a Time-and-Materials basis.
(Have them be seated when they're quoted the T&M fees.)
That will get a Service Engineer to the customer's site with the password to fix the system.
That SE will input it to the chassis and the system will get repaired.
Also request that the SR be dispatched and escalated through the customer's local District Service Manager with a request to waive the T&M charges. The DSM has the responsibility to maintain company Good Will and to maintain company profitability in the local district.
The worst that can happen is that the customer gets the service on a pay-as-you-go basis.
They could also get the charges waived if they put the system under contract.
They could also just get the charges waived.
It will all depend on what sort of relationship they have with the DSM. -

Hi
I would like if I install the Oracle in the following procedure, do I still need to run the catupgrd.sql.
1. Install Oracle 10.2.0.1 software only( i.e. without create any database instance)
2. Install Oracle 10.2.0.2 patch
3. Create an Oracle Instance using DBCA
Do I still need to run the catupgrd.sql for the newly created database instance?
DenisDo I still need to run the catupgrd.sql for the newly created database instance?No, you don't. Because database was created on already patched software.

I need to run a map against a particular dataset - how can i do it in OWB
Hello again :)
I need to run a map against table on a particular dataset (WHERE clause) - how can i do it in OWB?
The map is loading data from table A into table B (doing all sorts of wierd and wonderful things in between). Now table A had more (a lot more) data added which i have to load into table B.
How can i modify my map so that it only runs agains this newly added data (normally i would do a where clause).
i cannot find how to do it in OWB :(
The map i am runnig is fairy complex so i didn't really want have to create another table/view of the data i need then remap in all etc.
Any ideas would be greatly appreciated.
thank you very much

Well that is the thing - records are constantly added to table A all the time and then undergo tramsformations and loaded into table B. What i want to do is somehow indicate in the the map to only run agains records that have beed added (colmn2 = 'value').
At the moment i created a view for the desired dataset (colm2 = 'value') and remapped everything. But it is a bit of a pain:
1) there are a lot of functions and each takes a number of columns (i have some functions taking up to 6 diff columns)
2) i have data loaded to table A all the time and i need to then transform and load it to table B. so i try to aviod doing the whole re-mapping thing all the time.
In TOAD it would be a simple statment 'where colm2 = 'value' and all my functions will be run agains those records that satisfy the condition. How can i do it in OWB?
If i use filter - i would have to use 'mid' table where filtered records will be loaded and from that use 'mid' table as table A in the map. does this make sense?
the main disadvantage is the performance - moving data from one table to 'mid' table etc.
I tried using conditional load filter and it still doesn't do what i want.
After trying diff options i decided to ask people here about it. The only thing i have left to try is to ask Oracle support. I am sure it would be a 'user knowledge' as i am sure this functionality exist i just can't find any references to it.
Thank you very much for all your help. In fact this forum helped me a lot with a number of other issues :)
i just feel like a lemon coz it is very simple thing and i can't find how to do it...

URGENT: How to Run an existing Oracle apps page in Jdev 10g
Hi All,
I have downloaded Jdeveloper 10G with OA Extension from the patch 5856648. I am able to successfully run the "test_fwktutorial.jsp" and "HelloWordPG.xml". I need to customize an existing Oracle apps page for one of our client requirement. I've done the following:
1. Downloaded the BC4J components of the page which include xml and .class files from $JAVA_TOP/oracle/apps/ego and placed it in myproject( C:\p5856648_R12_GENERIC\jdevhome\myprojects) and also myclasses( C:\p5856648_R12_GENERIC\jdevhome\myclasses) folder of my jdeveloper.
2. Downloaded the mds PG.xml from $APPL_TOP/ego/mds and placed it in C:\p5856648_R12_GENERIC\jdevbin\jdev\oamdsxml\fwk with the appropriate folder structure.
I need to extend one of the VO and one of the controllers from the above standard oracle files. But since there are only .class files in the server, if I open the .class files, the methods are missing in those files. By decompiling the class files also, during run time it gives me error.
What is the right approach and steps to use the existing Oracle apps files. Is there some way in Jdeveloper where we can set the source of java file with compiled .class files. I'm not able to work in the Jdeveloper for this customization. Please could some one help.
Thanks & Regards,
Anita1st thing to make sure is that you want to do changes for an R12 instance because that's this version of Jdev is provided for.
Class files are required in myclasses folder only. Also page xml files should be in myprojects folder with the appropriate folder path.
Decompiling class files are only way to work with them.

Hi ODI discussion folks,
I have a couple of questions from an Oracle partner that I'm trying to find a definitive answer for if possible. The partner is setting up ODI 10.1.3.4.0 for a customer who insists that the absolute minimum amount of access to the file system is granted due to corporate security policies.
I have checked the bundled ODI documentation but couldn't really find anything about file system permissions needed to run the ODI client. I was pointed towards the "Setting Up Security for an Integration Project — What to Consider" document but this does not mention a great deal about how much access to the file system is needed for the ODI client to function.
What the partner is asking is the following:
"1. What are the minimum file/folder permissions needed for the ODI client installation? I'm installing at xxxxx
and their machines have to be locked down as much as possible.
2. Say you have 3 users all wanting to run integrations etc and the Master and Work
repositories have been set up. An admin installs the ODI client but doesn't
create the connection to the Master repository. What are the minimum
file/folder permissions required on the client machine to:
a) create the connection to the repository
b) run any subsequent integrations?"
If anyone can advise on this then that would be much appreciated.
Regards

user648991Hi Craig,
How are you?
Let me try to contribute a little....
1) The minimum requirement is for its own installation directory, there is no reason to have access to other directories unless if it is necessary to read files from some other directory at the client
2) Again only to its own install directory. The connection setting is recorded at \bin install directory. After that, all information are recorded at repository, there is no client work.
Be free to contact me by email or phone if you have any new doubt. You can get my email from my profile.
Does it respond your doubts?

Problem running forms in Oracle 9i IAS iSuites
Hi,
I'm trying to get Forms 6 running on an Oracle 9i IAS iSuites application server. When I try to access a form via the web I get a HTTP-500 Internal Server Error. The Apache\Apache\logs\error_log file contains the following entry:
[Tue Oct 06 11:39:05 2009] [error] [client 159.207.200.55] Premature end of script headers: d:/oracle/806/tools/web60/cgi/ifcgi60.exe
I've tried fiddling around in various configuration files but without more detail about the error I'm not sure what to do. Does anyone have any advice on how to go about debugging this problem?
Thanks
AdamHi there,
installing 6i for 8i on the same box is not a problem. I find it better, on a personal pc to have them in different homes.
- create a folder called 'Oracle6i'
- when prompted for the install home - point to this new directory
once the installation is complete you will need to copy the tnsnames.ora file from the oracle database home and paste it into the corresponding directory of the oracle6i installation. -
Making Siebel Run Fast with Oracle CBO – New PPS Recommendation - optimizer
Hi All,
I have some good news if you are upgrading to Oracle CBO. This is a big new find that we discovered a few weeks back.
There is a certain class of queries that run very slow with the default Siebel recommended settings. Please keep in mind that in order to properly do explain plans in 10G with Siebel SQL you need to issue the following alter session statements. Also if you are using TOAD you have to uncheck the run queries in parallel since if that option is checked a new session will be launched and your options won’t be set.
ALTER SESSION SET OPTIMIZER_MODE = FIRST_ROWS_10 ;
ALTER SESSION SET "_OPTIMIZER_SORTMERGE_JOIN_ENABLED" = FALSE ;
ALTER SESSION SET "_OPTIMIZER_JOIN_SEL_SANITY_CHECK" = TRUE;
ALTER SESSION SET "_HASH_JOIN_ENABLED" = FALSE;
The key new find is that the Oracle recommendation of setting optimizer_index_cost_adj = 1 is wrong! Our new recommendation is to set this parameter to 10.
Here are some more details. This is not a silver bullet for all your Oracle performance tuning issues. Remember it is best to tune specific things that are slow from an end users perspective. In fact that is how we discovered this issue and its solution.
There is one specific class of queries that this setting will fix. You can issue alter session statements to see the difference in your explain plans. Here is how you will know the query:
• Where clause on an intersection table and index that exists that would find just one row. This is the index we want Oracle to use.
• Order by on BC base table and another index exists that would satisfy the order by. We don’t want to use this index since millions of rows would be accessed.
• Explain plan shows the index for the order by is used instead of the index for the where clause that would have found a single row.
Here is the actual statement we encountered that lead to our discovery.
WHERE
T8.PR_HELD_POSTN_ID = T2.PAR_ROW_ID (+) AND
T2.BU_ID = T5.ROW_ID (+) AND
T7.ROW_ID = T4.PAR_ROW_ID AND
T7.ROW_ID = T8.PAR_ROW_ID AND
T7.ROW_ID = T3.PAR_ROW_ID AND
T7.ROW_ID = T6.PAR_ROW_ID (+) AND
T8.PR_RESP_ID = T1.ROW_ID (+) AND
(T8.EMP_FLG = 'Y') AND
(T3.LOGIN = 'UATUSER')
ORDER BY
T8.LAST_NAME, T8.FST_NAME
In addition at OOW this week we heard that an Oracle RAC expert presented Siebel on RAC and recommended setting this parameter back to its default of 100. We also talked with a very senior DBA colleague who made the same discovery over a year ago and is running with is parameter set to 25.
I can tell you that for us any setting from 1-9 gave the bad access path. 10 fixes the issue.
This find is so important that we wanted to get this out to the Siebel community ASAP.

web: www.ponderproserve.comHi All,
I know it is bad to reply to your own posts but this one is too good. Here is another example of this that all of us have.
With oica = 1 the m1 index is used and this runs a long time. With oica = 10 m6 is used and that clearly is the index Oracle wants to use since it matches the where clause exactly.
This is from the basic select we all run as part of Server Tables Clean Up. I am even including the alter session statements so you can see the drastic improvement yourself.
ALTER SESSION SET optimizer_mode = FIRST_ROWS_10;
ALTER SESSION SET "_OPTIMIZER_SORTMERGE_JOIN_ENABLED" = FALSE;
ALTER SESSION SET "_OPTIMIZER_JOIN_SEL_SANITY_CHECK" = TRUE;
ALTER SESSION SET HASH_JOIN_ENABLED = FALSE; -- "_HASH_JOIN_ENABLED" in 10G
ALTER SESSION SET OPTIMIZER_INDEX_COST_ADJ = 1; -- then change this to 10 and run EP again.
SELECT
T1.CONFLICT_ID,
T1.LAST_UPD,
T1.CREATED,
T1.LAST_UPD_BY,
T1.CREATED_BY,
T1.MODIFICATION_NUM,
T1.ROW_ID,
T1.ACTION_ID
FROM
SIEBEL.S_SRM_REQUEST T1
WHERE
((T1.STATUS IN ( 'SUCCESS' ) OR T1.STATUS IN ( 'EXPIRED' ) OR T1.STATUS IN ( 'COMPLETE' ))
AND T1.TGT_DELETE_TS <= TO_DATE('11/20/2007 16:26:27','MM/DD/YYYY HH24:MI:SS'))
