Listener configuration for external procedures

i am running Oracle 10g database release 2 on a windows platform.
I have gone thru the online documentation for configuring a separate listener for the extproc agent.
But i wonder if this listener.ora setting is the same on all platforms including Windows.
"EXTPROC_DLLS=ONLY:/home/xyz/mylib.so:/home/abc/urlib.so,LD_LIBRARY_PATH=/private/xpm/lib:/private/mylibs, MYPATH=/usr/ucb:/usr/local/packages,APL_ENV_FILE=/apl/conf/env.txt"
is it okay for me to just copy this and paste into my ENVS value in the listener.ora file.
How different are the path(s) on Windows platform?

you just check tnsping,lsnctrl ,check status of database..
lsnctrl start again after stopping it first,
then startup through internl in svrmgrl
hope it may effective..

Configure oracle for external procedures

Hi
I'm preparing to install 9iAS. I'm trying to configure oracle for external
procedures. When I tested to see if I have an external procedure listener I
got a no listener message (below). My tnsnames and listener files are below.
Can someone comment on what I'm doing wrong ?

Automated Runtime Configuration for External Services

Hello,
in relation to my bachelor thesis I was wondering if there is API or another way to set the backend systems destinations for external services dynamically and not by entering the information in CAF Runtime.

What Is an Appropriate Hostname & DNS Zone Configuration for External DNS Setup?

I setup servers that are hosted on a secure external data centre. The data centre has its own DNSS, so the DNS service is never setup on the server itself, and is handled by the data centre. I have already setup a handful of servers, and they all seem to be working well. Nevertheless, a couple of people in these discussions have told me, that I'm not setting the servers up 'properly' because of the way I'm naming the server - ie., they believe I'm assigning a 'wrong' hostname - and because of the way I'm setting up subdomains in the zone file. Here is how I'm currently doing it:
CURRENT SETUP:
The server is public, and it is also the ONLY machine publicly in the domain zone. So, if the client's domain is "example.com", there is only one machine that will respond to all services in that domain. Because of this:
- Server Hostname: "example.com"
- reverse DNS PTR record points to "example.com"
- 'mail.example.com', 'www.example.com', 'ftp.example.com', etc, are all setup as A records that point to the same IP address as "example.com".
This has been working fine so far. I have not had any problems with any service, including mail. However, a couple of people suggested that "example.com" is not a fully qualified domain name, and that this setup is therefore 'incorrect', and that it will cause me problems in the future. They suggest I should be setting these servers up like this:
SUGGESTED SETUP:
- Server Hostname: "server.example.com"
- reverse DNS PTR record points to "server.example.com"
- setup "www.example.com" as a record pointing to the same IP address as "server.example.com", but avoid setting up other subdomains unless absolutely necessary - ie., tell client to use "server.example.com" as the 'proper' address for mail/ftp/etc.
Technically, 'net', 'company.net' and 'server.company.net' can all be fully qualified domain names, if each one of them points unequivocally to a single IP address. An domain name is not fully qualified, for instance, when it points to a subnet instead of a single IP address. Using "example.com" as a FQDN is technically correct. However, what is 'technically correct' and what Server considers acceptable are not always the same thing....
I certainly don't want my clients to have problems in the future, and if OS X Server is going to misbehave because of the way I'm setting up my hostname and zone files, I need to know for sure NOW rather than later!

I'm the "other people" referenced here.
For general information on DNS, please acquire and skim a copy of Cricket Liu's DNS and BIND book. It was on its fifth edition when last I checked. DNS server on OS X Server is the ISC BIND server, which is discussed in that book in some detail.
If configuring OS X Server in a data center, the OS X Server box probably does not want (nor need) to be running a local DNS server. (Running local DNS services just means that DNS server will potentially become part of a DNS DDoS, if who can issue queries to the server isn't carefully controlled.) Use the DC DNS server(s).
If you want the domain itself to be used as an IP address (eg: example.com), then that's usually an A record, particularly if you're getting email via that domain (and not an MX record going elsewhere). Some versions of OS X Server have had some issues with setting up this record within Server Admin.app and Server.app.
The previous issues were likely due to stale DNS translations lurking within the configuration, and caching of that data up to the TTL. (FWIW, this discussion is related to this thread and this thread.)

SSF configuration for external Smartcard Readers

Hello colleagues,
I 'm working at a customer who is implementing a SAP project (R/3 4.6C SR2), in which is involved the goverment.
The goverment is forcing to the customer to implement digital signature in some steps of his business process, one of this steps is running on SAP R/3 system. The digital signature will be used with digital signature in order to "package" some critical data like "billing amount", for instance.
The goverment is imposing the smartcard encryption solution, that is hardware encryption.
I have been looking for information about it, so I understood the following:
1._ Some smartcards vendors are compliance with SAP.
2._ I need to install in the server running SAP the smartcard and the smartreader in order to manipulate and to access the encryption functionality.
3._ The smartcard is configured in SAP by transaction SSFA and other reports.
4._ The encryption functionality is accessed by SSF function group.
I downloaded the documents "SSF user guide", "security quick guide: digital signature" and "digital signature in FI".
I've found into a paper called "Digital Signatures
in SAP Applications - Web App.Server 6.40" the following:
1.3.1. SSF for the ABAP Stack
The SSF Library for the ABAP Stack is used in applications that are written in ABAP. It supports the functions for creating and verifying digital signatures (PKCS#7), and functions for encrypting and decrypting documents.
SSF requires an external security product to provide these functions. The SAP Security Library (SAPSECULIB) is delivered with the SAP system as the default product. However, the SAP Security Library only supports digital signatures without cryptographic hardware (SmartCards, SmartTokens, Cryptoboards). Instead of the SAPSECULIB, customers can also use the SAPCRYPTOLIB, which can be downloaded from the SAP Service Marketplace. The SAPSECULIB supports the DSA (Digital Signature Algorithm) algorithm, and the SAPCRYPTOLIB supports both the DSA and the RSA algorithms. The algorithm that you must use in your signature process depends on the CA that issues the certificate. Most CAs use the RSA algorithm. Note that country-specific export guidelines apply in the case of the SAPCRYPTOLIB. For more information, see SAP Note 397175.
For support for encrypting and decrypting documents, and for generating digital signatures using cryptographic hardware, an external security products from our partners is required. These security products use SAPs SSF interface and are certified for this by SAP. For a list of the certified products, see the SAP Service Marketplace under http://service.sap.com/securitypartners, and then choose the link Partner for Secure Store and Forward, digital signatures (SSF).
The SSF Library for the ABAP stack is available as of SAP Basis 4.0.
I don't undertand how is the relationship between SAPCRYPTOLIB and the SmartReader Card established/configured.
We think about the "Government of Chile" will deliver the customer a SmartCard Reader from Schlumberger (Cryptoflex 16K Card).
Should be great if you can provide me with any useful information in order to understand how to implement this configuration.
Best regards, Carlos

Hi,
Thanks a lot for your answer. I have more questions:
As I mentioned before, the Government office will provide a SmartCard reader to the customer: it's "Cryptoflex 16K card from Schlumberger". You can take a look to its features here:
http://www.cryptoflex.com/Products/Cryptoflex_Features/cryptoflex_features.html#
There, you can see the following:
Supported Applications and Platforms
Integrates with PC/SC
Integrates with PKSC#11 >>> (*)
Entrust Ready
Plug & Play with Windows 2000 and Windows XP
Axalto SDK
In the document about Digital Signatures "DigSig_Netweaver_BestPractices_en.doc", you can see the following:
1.2.1 PKCS#7
PKCS#7 stands for Public-Key Cryptography Standard # 7. The PKCS standards are specifications that were developed by RSA Security for secure information exchange using the Internet. PKCS#7 is currently a format established in the market. It describes a wrapper format, meaning that the output format does not correspond to the input format. If, for example, a PKCS#7 signature is attached to a PDF document, the document is then in PKCS#7 format. This format is a binary format, which in turn means that direct display is not very good, and is not suitable for a user. A special tool (viewer) must therefore be used for display. Unfortunately, usable PKCS#7 viewers are not currently available on the market. This format is very suitable for purely automatic processing (without a display component for the user).
SAP offers the PKCS#7 signature on the ABAP platform (as of SAP Basis 4.0B) and on the Java platform (as of SAP Web AS 6.30).
So here are my questions:
1) From above, can you tell me if I'm wrong, or this SmartCard ("Cryptoflex 16K card from Schlumberger") is incompatible with SAP Digital Signature implementation (the Smartcard uses PKCS#11 -see (*) above- and SAP uses PKCS#7)?
2) I didn't find to Schlumberger as a certified partner into the SAP link for Certified Partners for Digital Signatures:
http://www50.sap.com/softwarepartnerdir/products/certify/prod_def.asp?DescID=259&ProdDesc=Digital%20Signatures%2C%20Encryption%20and%20SSF
Does it mean that this partner can't provide SSF compatibility?
3) Can you provide me any kind of documentation in order to understand what are the whole configurations that need to be done from the "basis" side (if questions 1 and 2 are false) in order to configure this arquitecture?
4) Can you explain a little bit how the SAPCRYPTOLIB is used in this context? I mean, should we need it in order to encrypt/decrypt digital signatures/envelopes?
Best Regards, Carlos

Listener configuration for 2 db instance in a single node

Hi,
I have configure a 11gR2 server with 2 db instance (A and B), but I have only one listener (default) to server this two db instances.
Is this the recommended configuration or should I have one listener for each db instance? e.g Listener_A and Listener_B. I think it will be usefull in cases when I need to block the access to one db instance (A) without shutting down the database, by just turning off the proper Listener.
With my current configuration I am not able to do that since if I turn of the only listener that I have both dbs will not receive any other connections.
Am I correct?
Regards,
Edited by: ashum on May 13, 2011 8:21 AM

You are right that there is some value in going to the trouble to set up a separate listener for each database. Whether you take this approach depends mainly on how satisfied you are with the alternatives and how much trouble you want to incur in setting up and maintaining multiple listeners. We use separate listeners for each of our databases and really like the granularity it provides in limiting the scope of outages.
If you take the multiple listener approach, you will need to either use separate ports for each listener, or bring up a virtual ip on your server so that the second listener can run on the virtual ip.

SCOT Configuration--for external mail

Hi All,
I am trying to configure SCOT on my solution manager server. and able to send mail inside comapny mail domain but not able to send mail on any external mail domain like yahoo,hotmail.gmail.
we are using MS exchange server for mailing. please advice me if any further setting require on Mail server side.
Thank
Gyan

Hi,
Yes this is because your SMTP email server does allow sending emails to the outsid world.
If you are using SAP WAS 6.10 or above you do not need any extra configuration you need only to follow the following steps:
https://service.sap.com/sap/support/notes/455140
This is because the SMTPplug-in from WAS 6.10 and onwards - supports all SMTP mail gateways and you do not need any SAP Exchange Connector as well to connect to MS Exchange Servers. Please find below the details from SAP as well:
https://service.sap.com/sap/support/notes/122657
if you have followed all the steps as mentioned in sap note 455140 above, please liaise with your M/S Exchange Server administrator so that he can unblock the sending of emails to the outside world as well, if that is permitted.
- Regards, Dibya

Need help with classpath configuration for external jar files

We have coded our own JAAS login module, and it uses classes located in jar files, and these jar files were not created using SAP dev studio, e.g. they were provided by a third party vendor as a set of tools.
So, how do we deploy these jar files so that our SAP JAAS login module can find them ? We found we can run consoleconfig.sh to change the classpath which SAP J2EE engine uses, but we wondered if there was a better way to do this. Of course, if the jar files were created by us, we can include them in the dev studio project and they would be deployed using SDM, and this would not require any changes to classpath using consoleconfig.sh
Thankyou in advance for your help.

I noticed nobody has sent any feedback on this yet, so I wondered if I have posted to the wrong forum ? Any thoughts on this ?
Thanks,
Tim

External procedures for RAC system

Hi Experts,
I have 4 nodes 11.1 RAC in red hat. I saw some node listener configuration with IP=FIRST and other nodes does not have IP=FIRST entry.
I made a search onlin and get statement as IP=FIRST at listening endpoints are for external procedures in the database.
I want to know which means is for external procedures in RAC ? does expert can show some example ?
Thanks
JIm

No the IP=FIRST is not for external procedures. It is to restrict the listener to listening on the specific IP address specified not just the port on any address. This is explained in the NET SERVICES GUIDE

Problem in Calling External Procedure

Hello,
I am trying to call external procedure written in C from PL/SQL.
Here are the codes :
For external procedure:
#include<stdio.h>
void extproc_fn ( void )
FILE * file_handle;
if (( file_handle = fopen ( "/root/cprogs/extproc.out", "a" )) != NULL )
fwrite ( "External Procedure Testing", 26, 1, file_handle );
fclose ( file_handle );
I have created library as :
create or replace library extproc_lib as '/root/cprogs/extproc.so';
And the procedure :
create or replace procedure extproc_proc as
external
name "extproc_fn"
library extproc_lib
language c;
My listener and tnsname is configured correctly.
But when I try to connect to Oracle by that tnsname, extproc program core dumps under $ORACLE_HOME/network/log directory. Under WinNT, it creates a Dr. Watson error.
Any idea what might have gone wrong.
Thanks in advance.
Soumen Ghosh

hi there,
everything u did is correct as far as i recollect about external procedures ,the only thing that i suppose is missing is that u forgot to grant permissions on the library to the user...pls check this once i hope this works...

External Procedure call from Trigger

I'd like to call an external C Procedure from
an Oracle Trigger.
In trying to get an example to work, after setting up the listener and tnsnames.ora for external procedures, the following SQL*Plus command behaves strangely:
CREATE LIBRARY TTest as "c:\winnt\system32\TTrigger.dll";
After entering this, the command line prompts for more data as if the command was not terminated. Tried single quotes, double quotes, forward slash, backward slash...
What is wrong with this command?
Thanks

hi,
COuld you send me the configuration parameters for listner and TNSNAMES? I am working so hard to set it up but getting stuck and I am sure that I am missing some configuration set up.
Please could you mail your tnsname a nd listner files to bellow shown address?
[email protected] ?
Thanks in advance

oracle uses the default scott /tiger login to test the connection,
try using the userid / pwd you gave when you installed oracle.. (sysman or sysdba who has full rights )
