A question about transparent gateway,somebody help me plz!!

hi all:
i met a problem while trying the transparent gateway for ibm drda
1.i have the listner.ora configured like this:
=================================================================
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = felix)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(PROGRAM = tg4drda)
(SID_NAME = TEST)
(ORACLE_HOME = E:\oracle\oradrda)
=================================================================
2.and the tnsnames.ora configured like this:
=================================================================
TEST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.18.10.11)(PORT = 1521))
(CONNECT_DATA =
(SID = TEST)
(SERVER = DEDICATED)
(HS = ok)
(HS = OK)
=================================================================
3.and the initTEST.ora configured like this:
=================================================================
set DRDA_CONNECT_PARM=localhost:446
DRDA_REMOTE_DB_NAME=test (database name of db2)
=================================================================
then i log on as user system and create a database link dblink1.But when i try the sql statment "select * from t1@dblink1"
such error came up:
# ORA-28545: error diagnosed by Net8 when connecting to an agent
NCRO: Failed to make RSLV connection
#ORA-02063:preceding 2 lines from dblink1
somebody help me plz,tell me how to deal with such a problem,thanks a lot!!!
Best regards!

I strongly recommend you to read the following metalink note. Note:234517.1
ORA-28545:
SQL> select * from all_catalog@demo;
select * from all_catalog@demo *
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
NCRO: Failed to make RSLV connection
ORA-02063: preceding 2 lines from DEMO
Resolution:
There's something wrong with the SQL*Net :
- checking the SQL*Net -> Listener configuration with TNSPING: tnsping <SQL*Net alias>

Hi Felix,
Please take a look at note 234517.1 on metalink (copied below).
This note explains how to resolve the following error messages when using Transparent Gateways or Generic Connectivity:
ORA-3113; ORA-2019; ORA-2085; ORA-12154; ORA-28545; ORA-28546; ORA-28509; ORA-942; ORA-904; ORA-28500;ORA-28528
SCOPE & APPLICATION
This note should help to solve common error messages when using generic
connectivity or gateways.
Common errors with gateways or generic connectivity
Here are the English descriptions of each error; to compare your message
with the message below, you can alter your current SQL*Plus session
and compare your message with the messages listed in this note:
alter session set nls_language=american;
ORA-3113:
SQL> connect system/manager@tg4msql;
ERROR:
ORA-03113: end-of-file on communication channel
Resolution:
You can't connect with SQL*Plus directly to the foreign
data store. HS or Gateways are only designed to work with
a database link from an Oracle database to the foreign
data store
ORA-2019:
SQL> select * from all_catalog@demo;
select * from all_catalog@demo
ERROR at line 1:
ORA-02019: connection description for remote database not found
Resolution:
Create a database link to connect to the foreign database
create [public] database link <db link name>
connect to <user of the foreign datastore>
identified by <password of this user>
using '<SQL*Net ALIAS>';
For case sensitive usernames/passwords of foreign databases,
surround the user and password with double quotes.
create [public] database link <db link name>
connect to "<user of the foreign datastore>"
identified by "<password of this user>"
using '<SQL*Net ALIAS>';
ORA-2085:
SQL> select * from all_catalog@tg4msql_v91;
select * from all_catalog@tg4msql_v91
ERROR at line 1:
ORA-02085: database link TG4MSQL_V91.DE.ORACLE.COM
connects to HO.WORLD
Resolution:
This problem is related to GLOBAL NAMES.
The simplest way to disable global naming is to alter
the current session.
alter session set global_names=false;
The other solution is to add a global_name to the
gateway/hs:
HS_DB_NAME = <datasource>
HS_DB_DOMAIN = <DOMAIN>
But the HS_DB_NAME must not exceed 8 characters and
must not contain any extra characters. If this is not
possible, the globale naming can be disabled by setting
GLOBAL_NAMES = FALSE in the init.ora of the database
as well
ORA-12154:
SQL> select * from all_catalog@demo;
select * from all_catalog@demo
ERROR at line 1:
ORA-12154: TNS:could not resolve service name
Resolution:
The database link uses a SQL*Net alias not specified
in the TNSNAMES.ORA of the database server.
Query the data dictionary to figure out the 'HOST'
specified for the database link:
select db_link, host from user_db_links;
or
select db_link, host from dba_db_links;
The 'HOST' value is the alias of the SQL*Net.
Please make sure it exists in the TNSNAMES.ORA file
present at the Oracle database server.
ORA-28545:
SQL> select * from all_catalog@demo;
select * from all_catalog@demo
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
NCRO: Failed to make RSLV connection
ORA-02063: preceding 2 lines from DEMO
Resolution:
There's something wrong with the SQL*Net connection:
- checking the SQL*Net -> Listener configuration with TNSPING:
tnsping <SQL*Net alias>
TNS-12545: Connect failed because target host or object
does not exist
The HOSTNAME specified in the TNSNAMES.ORA is invalid
Try with the OS ping to resolve the hostname / IP adddress
TNS-12541: TNS:no listener
The hostname specified in the listener.ora points to a
machine without an Oracle listener, the listener on that
machine is not running or the port number is wrong.
NO ERROR with TNSPING:
This might be caused by an invalid SID configuration.
Please make sure, that the SID in the listener refelects the
SID specified in the TNSNAMES.ORA. Make sure you don't mix
SID syntax with SERVICE_NAME syntax.
If everything is configured well, please make sure that
lsnrctl status shows at least one service handler for
hsodbc. Probably restart the listener AFTER changing
the listener.ora file.
Still no error found, then please enable listener tracing
(level support) and have a look at the listener.trace file
after retrying the same select statement again.
In the file you should see the connect from the Oracle
database to the listener. After a few lines you should see that
the listener tries to open 2 pipes. Does this work or does it
fail and again a few lines later you see a hex/ascii block that
conatins an error stack like:
ERR=12500, CODE=12500, EMFI=4, CODE=12560, EMFI=4?
Then please check again the listener.ora file; is the
ORACLE_HOME directory specified within the listener.ora file
correct? Or if you are using environment variables in the
listener.ora please replace them with absolute paths.
ORA-28546
CAUSE 1:
SQL> select * from all_catalog@demo;
ERROR at line 1:
ORA-28546: connection initialization failed, probable Net8 admin error
ORA-02068: following severe error from DEMO
ORA-03113: end-of-file on communication channel
Resolution:
This error might be caused by a misplaced 'HS=' or 'HS=OK' key
word in the tnsnames.ora.
Make sure HS= or HS=OK is present and that the SID Connect String
looks like:
(CONNECT_DATA =
(SID = tg4msql)) <= there are 2 closing brackets! The HS
(HS=)) <= key word is OUTSIDE of connect_data

SQL> select * from all_catalog@test;
ora-28546: connection initialization failed, probable net8 admin error
ora-29511 lost rpc connection to heterogeneous remote agent SID ...
ora-02063 preceding 2 lines from test
Resolution:
This behaviour can be found in situations with a version missmatch.
For example the Oracle database is release 9.2.0.4 and the gateway
itself 9.2.0.1
=> The fix is to apply the same database patchset (gateway patches
are part of the database patchsets) to the gateway home as well;
or if the gateway 9.2.0.1 was installed into a 9.2.0.4 database
directory to reapply the database patchset.
ORA-28509:
Older gateways report this error instead of giving a
deltailed error description.
Resolution:
This error indicates the same as the errors described above.
They can be solved by checking the SQL*Net configuration
for the gateway / generic connectivity setup.

ERROR at line 1:
ORA-00942: table or view does not exist

ORA-02063: preceding 2 lines from DEMO
Resolution:
make sure the table exists in the foreign data store.
Pay attention that some foreign data stores are case
sensitive and thus the table_name must be surrounded
by double quotes.
ORA-904:
SQL> select irgendwas from "demo"@demo;
select irgendwas from demo@demo
ERROR at line 1:

Resolution:
This special combination of errors might occure after applying
the Oracle database and gateway patchset 9.2.0.5 WITHOUT
running catpatch (=the upgrade script of the database).
=> Please run catpatch. If it ran successfully but connectivity
still fails you may run
cathnohs.sql and caths.sql to recreate the HS data
dictionary tables. BUT BE CAREFUL: Running CATHNOHS drops ALL
gateway/generic connectivity related database links!
Hope this helps,
Mark.

I installed Mountain Lion and now some times when I start my mac it look with a black screen and white text. I'm really worry about it, can somebody help me?

I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

Don't worry, this is probably just Verbose Mode. It's perfectly harmless. If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM. See this article on resetting NVRAM if it continues to bother you.

Question about hard drive, need help lol.

Hey I'm kinda new to the MacBook world and have a stupid question. I am getting a late 2009 MacBook unibody (white polycarbonate, model MacBook 6.1... I believe) I am switching the original 250gb 5400 rpm hard drive out for a Seagate Momentus XT 750gb 7400 rpm hybrid hard drive. I want to keep everything on the original hard drive and just pop the new hard drive and start fresh with Snow Leopard. I'm going to purchase the SL cd from apple but I do not have the original grey start up cd that came with it (my girlfriends little sister lost it). Do I need to call apple for that cd in order to start fresh on my new hard drive or is everything I need on the SL cd?
Also how do I go about wiping the whole computer when I put the hard drive in and use SL? I want to essentially have a completely clean laptop with a new hard drive.
Thanks for your help in advance.

The SL disc you get from Apple will do everything you need. When you nstall the new hard drive there will be nothing to wipe, the drive is the only piece of that Mac hat stores anything so you don't need to worry about that. Post back and let me know how that hybrid drive works out....I'm interested.

Questions about VoIP, Can anybody help me?

Hi All,
I am learning VoIP now and I have serveral questions:
1. when I use "destination-pattern" command in "dial-peer" command, how will the number forwarded? For example: If I want to forward the number 123456 to ip x.x.x.x. If I use "destination-pattern 12...." to identify the number, the router will forward 123456 to x.x.x.x or 3456 to x.x.x.x? I think the answer is 123456. Am I right? And If I am right, there is another issue. What should I do if I just want to forward 3456 when received 123456? I think this is helpful to implement the dialing plan to use some digits as a prefix and discard the prefix to forward to another destination when received the number.
2. Can cisco router only support e.164 numbering plan? Can I use another? How can I explicity config the numbering plan in the router?
3. If there is a case like this:
PhoneA--R1--R2--R3--R4--PhoneB
R2 and R3 is connected via frame-relay. So when I use the "dial-peer" command in R1 and R4, should I use "voip" or "vofr" parameter?
Thank You!
Best Regards
Teru Lei

1) Here is an example of a dial-peer
Dial-peer voice 123456 voip #this mean this is a voip type dial peer name #123456
destination-pattern 123456T # mean when you will call 123456 and any number after that it will go to this dial peer
session target ipv4:192.168.0.1 # this will fwd the packet to that IP when you #will call 123456......
If you like to call somthing and send somthing else you can do translation rule
translation-rule 1
Rule 1 123456 3456
and on the dial-peer you need to set
translate-outgoing calling 1
2) Yes it support E.164
3) I would reccomand to use VOIP

Some questions about SAP Gateway

Hey, SAP gateway gurus,
I am new to SAP gateway and I created a SAP gateway service based on what I learned in the online tutorial video.
When a SAP gateway service URL is called in our shop, we will use a service account as the calling user.
(1) How and where the service account user name and password are passed? attach them to the URL?
The URL looked like http://server_name:port number/sap/opu/odata/sap/Finance_SRV/INTERNAL_ORDERS/?$format=json
(2) How can we pass and post a batch file in JSON format to a SAP gateway service? Is there any sample out there?
(3) How can I return the regular HTTP error message number in the DPC_EXT method if there is error during the query or update process?
Thank you in advance!

Question about photo shop, need help

    I downloaded a version of photoshop a friend recommended because I was looking for a free photoshop to use... So I downloaded it, and when I opened it, here is the response I got:
    "This program may not have installed correctly. If this program didn't install correctly, try reinstalling using settings that are compatible with this version of windows."
    I am using a windows 7 computer. Here is a link to the photoshop the dude sent me:
    I really want to figure out how to get this to work, I am terrible with computers and I don't even know if it is gonna show the link to the photoshop I had downloaded here on this post, but, I wanna figure out how to get this to work so I can go about creating my own mugen video game (I wanna learn mugen).. But first I need to figure out how to get photoshop to work, I am not very good with computers. Does anyone have any idea why I "may not have installed it correctly?
      I will attempt to type in the url to my photoshop download manually here,
          <link removed>
       If the first link doesn't show the photoshop I downloaded, hopefully the 2nd one where I typed it in manually will work... Does anyone have any idea why it's doing this or what I can do to get it to work?

Bravo to you for seeing the light that if you want to play you have to pay.
The best place to buy Photoshop is directly from Adobe.
Brace yourself: The full version of Photoshop is amongst the most expensive software out there.
You might want to look into buying Photoshop Elements. It does most of what the full version of Photoshop does and it won't break the bank.
And stay off eBay for buying Photoshop. The "too-good-to-be-true prices" you sometimes see are scams, and you'll likely get ripped-off.
For what it's worth, I don't know of too many programs that charge as subscriptions. Of course, if you consider that every few years new versions are released that require paying for the upgrade, that's not too different. But if you don't upgrade you can keep using the version you have for no additional cost.

Question about Regular Expressions, please help!

I have created an app which reads files and extracts certain data using regular expressions in JDK1.4 using Pattern and Matcher classes.
However it needs to run on JDK1.2.2 (dont ask). The regular expression classes are not available in 1.2.2 (the Pattern and Matcher class) so i am looking for something similiar which i can use?
I need something that loops through all the matches found in the file like how Matcher works i.e.
while (matcher.find())
// do this

Question about Dynamic Overclocking - Need help/advice

Hello,
I recently upgraded to version 3.9 bios on my MB (K8N SLI paltinum).
I had DOT enabled before the upgrade, on 9% extra. this worked ok. as soon as a program required heavy CPU, DOT kicked in and give me a 9% boost. and it also cooled off, back to normal operations when the CPU was idle again.
now, since the upgrade to 3.9, the DOT always stays at 9%? when booting up, when idling, always...? Is there a setting that I missed? or is it a bug in 3.9?
--> after the upgraded I loaded the optimized defaults.
thanx for any help.
S.

hi guys,
thnx all for the updates. I'm currently using DOT on 9%. It runs rock stable. IIf I set it on 11%, no problems.
C&Q is off, always was.
The problem with DOT is, that it doesn't do what it should do. (in 3.9 bios). nl, when the CPU runs on 0% load, no Over-clocking is need.
Any other settings that I should check?
Do I need to turn on Q&C?
thnx!

Two questions about defining class, pls help me

Hi, guys. I'm green hand and here are two questions puzzled me several days.
We know such example as below is a case of cyclic inheritance
class Base extends Base{
But I can't figure out why below is a case of cyclic inheritance too
class Base{
class Derived extends Base{
class Base{
I can't find the clue of cyclic inheritance. It's quite different from the case that a class extends itself or its subclass.
Another question is why the inner class can't have the same name of outer?
class Base{
class Base{
The compiler says Base is already defined in unnamed package. As it says, the inner class is defined in the
unnamed package, but we know below is correct.
class Base{
class Basic{
class Derived {
class Basic{
We know it's correct. But as the compiler says above, the different two inner class Basic are both defined in the
unnamed package. Why it's valid and why above is invalid?

A question about arrays. Please Help

Ok here is my question lets say i have a multie varible array such as
int[][] thisList = new int[3][64];And I have a number of other arrays that are single variable arrays, and which have data stored in them.
List1[64]
List2[64]
List3[64]is there a way i can store all these three list in the multie varible array?
for example i know i can do this, > Correct me if i am wrong
List1 = List2; where List1 one now contains all the elements that List2 has.
but is there a way i can
us the same format with a multie varible array, to store all three list in it.
such as thisList[1][] = List1; thisList[2][] = List2[]; Thanks

for example i know i can do this, > Correct me if i
am wrong
List1 = List2; where List1 one now
contains all the elements that List2 has.There will be one array. Both the List1 and List2 reference variables will point to that same array.
(By the way, convention in Java is for variables to start with lowercase.)
>
but is there a way i can
us the same format with a multie varible array, to
store all three list in it.
such as thisList[1][] = List1; thisList[2][] =
List2[];
You can do thisList[1] = List1 if thisList is an int[][] and List1 is an int[]. However, that will not copy any ints. It will just do the same as the above--cause the reference thisList[1] to point to the same array object as List1 does.
If you want to copy values from one array to another, use System.arraycopy.

Question about SAP Gateway to Netweaver Mobile 1.1

Hi Gurus.
I am trying to implement SAP Gateway to Netweaver Mobile 1.1 (Sales Scenario) for the first time.
I have read the Master Guide and the Configuration Guide... but I still don't get if the Sales Applications for Hand Held have to be developed from scratch or if they come in the add-on.
Could you please point me to the light?
thank you.

There is ONLY ONE reason to have to update your iPod to 1.1 and that's to use Apple's new FM radio. 1.1 is not required for anything else. Everything else works fine, in iTunes and otherwise.
My iPod works fine right now and I just want to be
able to put more songs and movies on it using iTunes
without going to the 1.1 FW.
If you want your iPod to keep working, stay away from 1.1. You have been warned!
I'm scared to even
synch my iPod right now after reading the horror
stories posted in these forums....
Don't be so silly. If you're running 1.0, just get on and enjoy your fully functioning, happy, smiley, healthy iPod.
Let's not get hysterical shall we?

Question about transparent background

Hi,
I have created a simple graphic with 4 layers on a
transparent background. When I save this image as a jpg, gif or
flattened png, the transparent background turnsto white. What
should I do to save it as jpg or gif with a transparent background?
Thanks in advance
Joe

Thanks pixlor.
I set the Export settings and then exported as both Gif and
png32. I opened the exported image in Photoshop CS3 and the
background looks transparent. I was happy.
Then I inserted the image in the blank HTML page. When I view
the page in Firefox, I can see the background color through the
image since the image background is transparent. When I view the
same page In Internet Expolrer, I see a bluish gray background
instead of being transparent. I don't understand where am I getting
this bluish gray color from.
Any clue?
Oh...sorry, yes. First, try index transparency, not alpha
transparency. For IE prior to version 7, you need to add some
JavaScript. For example, this script by

JPG: This format has all 16.7 million colors, but it
compresses by throwing away "high-frequency" information (sharp
edges will blur funny). This format is good for photographs and
other images where colors change slightly from one pixel to another
(as in gradients). This format does not have transparency.
GIF: This format retains color information, but can only
support 256 colors -
any 256, though. It supports transparency, you can set one
of your 256 colors to be transparent. This format is good for
graphics with areas of solid colors. This format can also support
multiple frames in the same file, giving rise to animation.
PNG: This format retains color information like .gif and has
16.7 million colors, like .jpg. It handles transparency, too.
What's not to love? Well, not all browsers show .png files
properly. The major ones will, though, so if you know your audience
is mostly on one of the major or newer browsers (intranet use?
check your log files?), then you should be okay.
Index and alpha transparency. Index transparency means, more
or less, "make every pixel that is
THIS color fully transparent and every other pixel fully
opaque. Alpha transparency (often done with a mask of some kind)
means you can set the transparency of a pixel in the range from
fully opaque to fully transparent, from 0-255. These images are 32
bit: 8 bits for Red, 8 bits for Green, 8 bits for Blue, and 8 bits
for alpha transparency.
For the Web, you probably want to use index transparency,
because support for alpha transparency on .png files can be a bit
flakey. Support for index transparency is pretty good with the
newer browsers, but if a good portion of your audience is using
older browsers, you have some design trade-offs to make.
Probably good to read up on things:
Google
search for png support in browsers.
