Problem in Databse Link Creation

I have created two Databases Named 'DBOLMMS' and 'MMS2' on same Server. There is User 'MMSUSER' in both Database and there two diffrent services for both Databases Named 'DABOLMMS' and 'MMS2' respectively. I wish to share some of the tables in 'MMS2' into 'DABOLMMS'. So I tried to Create Database Link using following command is SQL Plus
CREATE DATABASE LINK MMS2 CONNECT TO MMSUSER IDENTIFIED BY MMSUSER USING 'DABOLMMS2';
Link is created without error but when I try to access data using this link as following
SELECT * FROM TAB@MMS2;
I get following error
ERROR at line 1:
ORA-02085: database link MMS2.US.ORACLE.COM connects to MMS2
Pl. send solution on [email protected]
Thanks

Please check the following:
1. Create the DBLink name different than the Database name of the second DB.
2. in init.ora give global_names=false
Hope this will solve.

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

Problem in Purchase Requisition Creation

Dear Experts:
We are facing a problem while purchase requisition creation. We have created an Internal order No. 600406 and an Asset in Company Code AB01 but while creation of Purchase Requisition level when we are selection that Order and Asset in Purchase Requisition system automatically changing my Order no. 600020 instead of 600406. I've checked OKB9 where Order no. maintained as 600020 against Company code AB01 which I deleted and save but after that Purchase requisition asking for Order Number that means we have to maintain Order number in OKB9. Now can you please advise how can we get my current order number in requisition instead of any default number.
Thanks in advance and your kind suggestion is highly appreciated.
Best Regards.

Problem In time of creation wprk Scheduled...

Hi...
I have faced a problem in time of creation work scheduled, it is displaying a error massage like " Error while accessing public holiday calender on 20100101".
Can anybody help me to resolve the problem....
with regards,
Diptendu

Hi Diptendu,
I believe you are creating work schedule rule for the year 2009. So for this, u need to mandatorily generate holiday calendar upto Jan 2010.
This is because in order to generate workschedule rule for Dec2009, holidays in the holiday calendar should be assigned atleast in the month of Jan 2010 and then generate the holiday calendar upto Jan 2010. So the dates for generating holiday calendar would be 2009-2010
Hope this would solve ur issue.
Thanks.

Problem in process order creation.

Dear Sir/ Madam
i am facing a problem while process order creation.
the problem is:
Error when calculating cost for order ATFEDEC11 "see log Log is deleted when saving
Do you still want to save?"

Hi,
The log for production order preliminiary costing is not saved. Therefore, once the order is saved, there is no log available anymore (this is by the way a question of PP; none of the logs is saved).
Hope that helps...

PROBLEM IN CUSTOM IDOC CREATION

Hi Friends,
                I'm facing a problem in custom idoc creation plz try to assist me
1.As per the information i have i'm creating segment in we31
for cremas01 idoc.But when i enter the name for segment i'm getting message "Name range Voilation particular name which i had given is not permitted in customer system?
Plz clarify this,and are there any formalities which i should look for before creating custom idoc?
Good answers will be rewarded.
                                                                          Regards,

The Problem might be.... with the naming of the segment.
Standard segments should be created with 'E1' and all the custom segments are created using 'Z1' and the name with 8 characters long only is permitted.
Reward Points if useful.

Problems with Dinamic Link between Premiere pro CC and After Effects CC

I'm having serious problems with dinamic link between premiere pro and after effects, really serious problems that have 2 big projects in trouble (a documentary and a video clip) and I had to redo all the work pipeline to the consumer.
The documentary for a spanish TV was made on CC 2014 and a video clip was made on CC. Both of them with a lot of after effects composition in the premiere pro timeline. Render freeze, a lot of playback issues, and many more problems... Until I decided to remove these links between premiere and after effects and render out all the after effects compositions one by one and insert as clips in premiere pro. 1 week working away with back and fourth.
I've got a huge workstation:
i7 4990
32Gb ram
GTX780 3gb
256 gb system ssd
2 Tb project storage
*All my hardware and software are update.
I know that a lot of folks are on the same huge problem and I want to ask everyone:
How do you save this?
What is your pipeline?
Are there any solution?
Best practice to use dinamic link in a huge project?
Thanks,
Ruben Gimenez.

Thank You, Jim -
Unfortunately that specifically did not work.
Based on another comment sent to me, here is what did.
In PProCC
File > Adobe Dynamic Link > New After Effects Composition
In AECC
From that composition created from PPro, I imported the project (aep) initially created in AECC from another team member. Saved the file.
Back in PProCC
File > Adobe Dynamic Link > Import After Effects Composition

Problem providing download link for BLOB data in apex report
591953 Nov 19, 2008 1:55 PM (in response to 660436)
Currently Being Moderated
Good morning,
Here is how I have solved this problem.
1. The select statement in the sql for the report should not include the BLOB column. I decided to select only 2 columns, the column that has the key and the column with the filename.
2. On the first column ( the primary key ) I put in the format statement that was simply DOWNLOAD:TABLENAME:BLOB_COLUMN:PRIMARY_KEY
This works. I believe that the Oracle error I was getting was because I was trying to apply this format statement to the actual BLOB column.
So, it appears that you can use any of the columns in the report to hold the DOWNLOAD format statement since in the format statement, you are defining the BLOB table, BLOB column and the primary key into that column.
Hope this helps,
Don.

Problems working with linked files in illustrator

Hi everyone, i hope you can help me with this doubt that had given me problems since I started using illustrator. I'm using linked files in illustrator because i'm able to modify the files later, as I do in InDesign too, but in both cases I had have a lot of problems with the links, I don't know if i'm doing something bad, but this is what I do: I create a folder where I place my file (illustrator or InDesign) and the files that should be linked. Whit this i'm expecting of it to work like an html where the links works while they are in the folder, no matter if you move the folder, the links keeps working on the HTML.
But I have noticed that it doesn't work in the same way, because, I had have cases when the links work perfectly, but then i format my computer (Mac) and after that, I open my files againg but the links don't work already. I have exactly the same problem with my coworker, because im trying to edit a file with linked files since the place where it is in the other computer, obviously it opens perfectly there, but in my computer it asked to repair the links, so I select to repair automatically but I ask me to does it manually... So this is getting me tired, because I must repair the links here in my computer to work on it, and when for it get finished, my coworker should repair the links again, and this is going to be always we share files or i format my computer. It is important to mention that my coworker and me use mac with leopard and the same version of adobe (CS4).
So, as I said before, i dont knoe if my method is incorrect, should I do something different? any option to activate? or program that I should use? because I have herd a lot of Adobe Bridge, I don't know if this could have a option that could help me.
I hope finally somebody can help me with this doubt, because im sure that I'm not the only one having thie problem.
Thanks for your help

Hi. I am also experiencing this very annoying problem. Currently using version CS2, but this problem dates back to version 9. I check the box to link a tif file, not embed it, in Illustrator. All is well until I save and reopen the file. Suddenly the file is embedded. No other changes have been made to the folders or anything else. It just embeds itself and cannot be linked again.
So far, I conclude that something in the file itself has corrupted, because it is not possible to place a new file and have it link correctly again. So if I anticipate more changes, I create a new file.
Notice the upper left corner of the top toolbar. If you click on a file that has embedded itself, the file will be identified as "Group" instead of "linked file."
I've tried all kinds of things, like trying to ungroup it, trying to release a clipping mask, and so forth, to see what went wrong. Have not figured it out.

Hi guys. i have some problem with a link from a pdf on-line,when i click on it,the page adds a "%" at the and of the link and says "page not found" because of it

Hi guys. i have some problem with a link from a pdf on-line,when i click on it,the page adds a "%" at the and of the link and says "page not found" because of it.
This happens only when a load my pdf file on my server, because if i click on the link when the file is on my iPad, the page opens without problem.
Any help please?
thanx

the % sign is often used when there's a space in a name. HTML doesn't like spaces so it fills them with % or %20
try, on the end of that link, see if there's a space built into the page or the link when the page was made
On the web address you may be able to 'backspace' at the end and erase that space to get the address, but whomever made the page possibly put a mistake in the link

Problem connecting DataBase Link from windows oracle to oracle on Linux

Check the link SB provided. Keep in mind that the tnsnames file of concern is the one on the source database server.
