ORA-01653 error while executing a select query over DBLINK

Hi,
We have a query that is running to extract some data from a remote DB over DBLINK.
The query is failing by throwing the error "ORA-01653 -- Unable to extend.........".
Is this a problem with the "temp" tablespace of local database or is this with the "temp" tablespace of remote DB.
As far as my knowledge goes, I guess any statement , selecting data over dblink where the query is being fired actually in remote db over dblink uses the temp tablespace of that DB only and hence the problem should be with the temp tablespace of remote db only but I am not very sure about this.
Is there any chance that it can be problem with "temp" tablespace of local DB from where the query is being fired over dblink.
It would be really helpful if anyone can throw some light on this.
Thanks

The error stack will normally tell you if the exception is raised in the remote database.
You might try using the driving_site hint (see performance guide) to push work to the remote site or pull it local. It all depends on your particular query and explain plan.
Remember to use { code } (without the embedded spaces) tags to frame your code and explain plan so it remains formatted, if you post it here.

I am getting ORA-02063 error while copying bulk data from DBLINK

Hi all ,
I am trying to copy data from DBlink ,whenever i am trying to pull more data ,The db link break down ,
I have try to put /*+ APPEND */ (Hint) in insert statement.Below is the insert code from my procedure
from where i am getting below error
"Error in copy_data_pkg-3113 ORA-03113: end-of-file on communication channel
ORA-02063: preceding line from TESTDBLINK"
Insert code:
INSERT /*+ APPEND */ INTO target_tab
select
col1,
col2,
col3,
col4,
col5,
o_time
FROM padmin.V_tab1@testdblink
    where
trunc (sysmodtime) = trunc(sysdate)-1
and O_time >= al_time
and (CLEAR_TIME is null or CLEAR_TIME >= occur_time)
    and (res_code is null or (UPPER(res_code) not LIKE '%TEST TT%' and UPPER(res_code) not LIKE '%TEST SITE%'))
    and ((UPPER(BRIEF_DESC) not like '%TEST TT%' and UPPER(BRIEF_DESC) not LIKE '%TEST SITE%'))

    and catvar IN('POS')
and UPPER(action_var) not like '%SC_NET%' and UPPER(action) not like '%ROAM_NET%' and UPPER(action) not like '%PUP_NET%';
COMMIT ;
Please suggest me ,why i am getting this error.

Can you elaborate the thing... I don't think /*+ APPEND */ this is working for me ,still I am getting same error.
If you have any other suggestion,I would like to hear.
Should i not put commit after some 500 records inserted ? As i am putting commit once after whole data gets inserted.

Create materialized view across dblink gets ORA-980?

Hi!
Oracle 9.2.0.5. Creating a materialized view on on a synonym that points to a table across a dblink. I am getting a ORA-980 error that synonym translation is no longer valid. However selecting against the same synonym returns the rows or the count, etc. What am I missing here?
This is the code that is being run:
create materialized view gxp_sc_item as select * from sc_item_db2;
Hints, tips, ideas, etc. gratefully accepted!
Dave Venus

Hi!
Thanks for the reply!
Yes that is a solution, however why does the synonym work for everything else? I can't find anything that says this should not work.
Yes running 9.2.0.8 would be my first choice. The application vendor does not certify anything higher than 9.2.0.5.
Thanks!

Where clause won't propagate over dblink / function as where condition

Hi there,
I've here an rather complex problem with whom google couldn't help me.
<h3>The Situation</h3>
I've got two databases ( local db : oracle 10XE, remote db: non-oracle) which are connected via dblink. The connection works perfectly. On local db I want to execute this query:
select sum(revenue), year, brand1
from revenues@remote
where cus_encryptData('MFGR#12', 'mykey') = category -- <--
group by year, brand1
order by year;whereas cus_encryptData(<str>, <str>) is user defined function which turns a plaintext into a ciphertext. This function can for security and technical reasons only reside on the local db. Here is the definition:
create or replace function cus_encryptData2(plain varchar2, pw varchar2)
return varchar2 deterministic PARALLEL_ENABLE is [...]<h3>The Problem</h3>
This query works, although very slowly (because a lot of data has to exchanged between remote and local db). The execution plan suggests that the where condition is not propagated to the remote db. The only thing that happens on the remote db is the column select. But when I change the query to:
select sum(revenue), year, brand1
from revenues@remote
where 'dLWEfksdaAWE321asDcASd2' = category --'dLWEfksdaAWE321asDcASd2' == cus_encryptData2('MFGR#12', 'mykey')
group by year, brand1
order by year;the where condition is propagated and everything works as it is supposed to (only the aggregation is done locally, but thats ok).
<h3>The Question</h3>
Does anybody know how to get oracle to just send the result of cus_encryptData to the remote db or rather to resolve the function first before sending it to the remote db? Moreover, the solution should be as simple as possible, i.e. if possible only standard SQL.
Thanks a lot

I've here an rather complex problem with whom google couldn't help me.A colleague ran into the exact same type of problem, dealing with a db-link to SQL-Server some weeks ago. I created a work-around for hm, but now I'm struggling to recall what it is... Sheez... it has been a long week and it is late Friday afternoon.. ;-)
The basic issue was to get the local SQL parser to send the literal result (of the function) to the remote server to be parsed.
If memory serves, I winded up using dynamic SQL. Not actually dynamic string SQL, but passing the value as a bind variable instead of using a function in the SQL statement.
So instead of something line this:
begin
insert into local_table select * from remote_table@external_db where col1 = funkyFoo(123);
...Remove the function call and pass a bind variable instead:
begin
localVar := funkyFoo(123);
insert into local_table select * from remote_table@external_db where col1 = localVar;
...I'm not sure why Oracle behaves like this. I would have expected the driving_site hint to basically do the same - resolve the local function and use the returned value as a bind variable value in the predicate for the remote SQL.. and I vaguely recall this working when I had to use a foreign database (via the Oracle Transparent Gateway for Informix). But it could have been that the Gateway s/w was more intelligent than the generic ODBC agent typically used today...

Select from multiple tables through dblink

I am seeking help. Can I select multiple tables through a dblink from a remote database? I tried, it seems it always return ORA-00933 error. code like this:
select A.ID, B.CODE, C.TYPE_DESC
from TABLE_ONE A@db_link , TABLE_TWO B@db_link, TABLE_THREE C@db_link;
where A.ID = B.ID
and B.CODE = C.CODE
Thanks in advance.

Just as an FYI, from a performance standpoint, it is frequently the case (though certainly not guaranteed) that you'll get better performance creating a view on the remote database that does the join of all three tables and to use that view in your query, particularly if you're also joining in local tables. Optimizing SQL statements across database links tends to be particularly hard, a view often helps force Oracle to join the remote tables on the remote database which is generally what you'd want. Of course, this is not a guarantee, and you can always get explicit with hints to force joins to happen on one or the other system, but this is frequently the easiest starting point.

Performance problem with dblink

Hi!
I have 2 servers with a dblink join.
I push from server A to server B with an insert sentence 80 mb of data (blob datatype). It take between 4 to 5 hours to insert.
Server A and B are in the same office. (Windows 2000)
Somebody have an idea why it take this time to work?
Can I optimize the transfer ? If yes How!
thanks for your help

I strongly recommend you take the execution plan while running this activity or generate event 10048 trace and diagonse where the dealy is.
Once you get trace or execution plan, we could suggest you more realistic.
If you joins, you can use DRIVING_SITE hint.

ORA-02063 when selecting over DBLINK

Hey, I'm having an issue where a complex select is returning a 02063 (it has an 'invalid identifier' on a column that clearly exists)
I would post the query but it's pretty large and joins 2 views. One of the views selects through a dblink, so it's imbedded pretty far in. I cannot isolate parts of the query that are causing the issue because of this.
What I wanted to know is the best way to write the link or the view to avoid these parser issues. Here's the complete error message I get as well as the script for the link:
ORA-00904: "A"."BUYING_MEMBER_ID": invalid identifier
ORA-02063: preceding line from WEBAPP6
create public database link "WEBAPP6.REGRESS.RDBMS.DEV.US.ORACLE.COM"
connect to ABC_WEBAPP
identified by "<pwd>"
using 'abcdb';
And the script for the view which uses the link:
SELECT a.ID member_id, a.NAME member_nm, a.url member_url, a.address_1,
a.address_2, a.city, a.fda_license, a.is_abc_board_member,
a.is_gsabc_board_member, a.is_abc_foundation_board_member,
c.short_name state_id, d.code zip_cd, e.code county_cd, a.phone_main,
a.phone_alt, a.fax, b.financial_ctr_id, b.benchmarking_ctr_id,
b.piag_ctr_id
FROM MEMBER@webapp6 a LEFT OUTER JOIN lu_member_dw b ON a.ID = b.member_id
JOIN state@webapp6 c ON a.state_id = c.ID
JOIN zip@webapp6 d ON a.zip_id = d.ID
JOIN county@webapp6 e ON a.county_id = e.ID
UNION
SELECT member_id, member_nm, member_url, ' ', ' ', ' ', ' ', ' ', ' ', ' ',
' ', ' ', ' ', ' ', ' ', ' ', financial_ctr_id, benchmarking_ctr_id,
piag_ctr_id
FROM lu_member_dw
WHERE member_id NOT IN (SELECT ID
FROM MEMBER@webapp6)

Always use alias names! If you have no alias name, create one. Without alias the database can just guess where this column is coming from.
Consider UNION ALL instead of union (not sure if it is the same result).
Consider to create a view on the other database that joins all tables and that you access over the DB-Link.
There are also some hints that influences where the selects are executed (on your DB or on the other one), however I forgot the name of them (PUSH_SUB?).

DBLinks - need some more info

I have a plsql portlet that does executes a select and renders the data. The SELECT is on remote tables - uses db links.
Do DBLinks use a connection pool concept? I was trying to monitor the sessions to the remote db by:
select count(*), machine from v$session
where schemaname = '<schemaName>'
group by machine
If I ran the portlet 10 times, I saw 10 sessions from the machine. Eventually the sessions drop down after being idle for sometime .. but, if I let 100 simultaneous user's use this portlet - am I going to get 100 sessions ?

> Replication - yes, can be done, but the question is - how feasible is this, the refresh rate etc.
Consider that each time dbA runs a query against dbB, data is shipped from B to A. Even for the same query on the dame data, 100 times a day - that data needs to be shipped from B to A.
In comparison, with replication you pay once up front for the shipping of data. And you ship only cheap delta changes after the first expensive ship all data.
This is a lot more feasible IMO than paying the shipping price every single time a query is run on A.
And there are also other issues affecting performance. CBO related issues for example like forcing the CBO with the driving_site hint. Network performance between A and B. Etc.
What is the invariable fact of a network? It gets slower. Always. Until it is scaled up again. That is networks' entropy. And this can cause very serious performance problems that you cannot solve - until they scale the network again (if planned at all).
>My question was more on the lines of defining a database link to dbB from dbA. The dbA is
under my control. If I were to do this as a j2ee application, I would set the min, max
parameters on my connection pool. I would ensure that the idle connections were scaled down - I am trying to find information to do a similar thing on the "database link".
That is exactly what Shared Server connections are about. You set a shared server pool with a min and a max on dbB. These services sessions from dbA.
As for controlling client connections (which is what db links are), there is no pool as such. You can control the max allowed number of open links per sessions with the [url http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams139.htm#sthref588]OPEN_LINKS parameter.
You can forcible close all links in a session using the [url http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_2012.htm#i2231814]ALTER SESSION CLOSE DATABASE LINK command.

Commit though a DBLINK left incomplete

Hello there,
Doing an insert into a sysnonym, which is a view of a table on a remote DB through a BDLINK, leaves the transaction open.
This is Oracle 8.1.7
The same insert works if the table is a proper table and not a sysnonym to a DBLINK to a table in a remote DB.
When doing the insert, the program doesn't rise a SQLException, but the row is not inserted nevertheless. But if one tries to insert the same row, say by using sqlplus or toad, the following error shows up:
ORA-02049: timeout: distributed transaction waiting for lock.
ORA-02063: preceding line from ($DBLINK_NAME)
As far as I know autocommit is enabled, since I haven't touched the default, and inserting on the non-remote DB works ok.
Any hints on what can be happening here? Help would be much appreciated, thanks in advance,
Miguel Guzm�n

You only need the commit or rollback if you want to close the database link. As others have said, Oracle automatically starts a transaction when you select over a database link, and that transaction needs to be completed at some point. The "natural" commit at the end of your transaction will do fine for ending the database link transaction.
Many tools will "see" that you have an open transaction when you try to exit the tool (or close the particular session) and will prompt you for a commit or rollback to end the transaction.

Lock-ups while inserting to a remote database using a dblink

Our application runs across multiple instances of Oracle 8i - 8.1.6.
Throughout the day we run some batch processes to transfer data across these instances using dblinks. Ocassionally the process locks up and further investigation shows that the server from which we are pushing information out seems to have executed an insert statement on a remote instance (insert into test_table@tst_dblink select * from local_table) and is waiting for a return from the remote server while the remote instance seems to be hanging too. Oracle does not return any error but simply waits forever for the statement to finish.
If anybody has experienced this before can you please share any information you may have on 1. how to prevent this from happening or 2. How to make oracle give up on the transaction, roll it back and raise an error?
Thanks a lot....

Well, certainly we need more info to fix the problem! couple of "system states" on both the machines when the job is hanging would help. couple of "stack trace" of the shadow process will also help. please call local oracle support with the system state and stack trace.
Sounds like the job is hanging on some resource (lock,enque,latch,io...). oracle doesn't give up for few resources, like waiting on ST,latch, io etc. we have to kill the offending process if we want!!
just my 2 cents :)

            %_hints oracle '&max_in_blocking_factor 500&&max_blocking_factor 500&'.
I want value 500 dynamic,
So far I have tried
%hint oracle lv_oracle_string.
%hint oracle (lv_oracle_string).
WHERE (lv_oracle_string).     "where conditon with %_hints oracle '&max_in_blocking_factor 500&&max_blocking_factor 500&'.
Any other ideas?
Thanks in Advance

Samuel,
Thank you so much, whatever you mentioned, I have tried ealier, but it was giving me dump because of incorrect spacing in my string.
Given below sloved my problem.
CONCATENATE '''&max_in_blocking_factor ' lv_oracle '&&max_blocking_factor ' lv_oracle '&'''
          INTO lv_oracle_string RESPECTING BLANKS.

Thanks you so much again. You Rock

Select query in materialized view with two dblinks

Hi All,
We have oracle 10g On windows.
We are trying to create materialized view. Scenario is we have base table on other database and we are creating mview on different database.
Basa database have two schema's and i am selecting records from that two schema's using two private db links.
But when i am tryin gto create mview its not getting created. After 15 hrs. its still showing creation command and not finished.
Query is :-
Is it good practice to have two db links in select query of materialized view.

If the former, you ideally want the local Oracle db to send the join to the remote database, and for the remote database to drive the join between those 2 tables. There is a hint (<i>driving_site</i>) that can be used - or the join query can be defined on the remote database as a view, and the local materialised view can then use that remote view.
If you have 2 different db links and joining across these - usually a bad idea to perform distributed database joins. There are lots of limitations as to how the tables can be joined. Worse case, full table scans of both remote tables, pulling all the rows from the 2 remote database tables to the local database, and joining these on the local database.
I have seen some severe performance issues in the past as a result of distributed joins. I'll rather use 2 materialised views for pulling both distributed tables's data locally, and then do the join on local data (using indexes, partition pruning, etc)Hi Billy,
My scenario is i have two database database A and database B. Database A is having two schema's SCOTT AND HR. SCOTT schema have select privileges on HR schema.
DB LINK is between Database B to Database A. name is db.link.B.A.oracle.com.
What if i priovide while creating materialized view, the schema name before the table name in database B for this particuler table so it will pick up the table from that schema using same DB LINK(db.link.B.A.oracle.com.) that i am using to fetch records from SCOTT schema.
Above schnario is like two base schema's and one db link using two schema.

Report Developer Control Of Applying Hints to Analytics Queries

There are numerous ways to apply hints to the queries generated by Analytics:
- Table level
- Join level
- Evaluate calculation
Each has its advantages and drawbacks.
- Table level: applies the hint to every query that references the table.
- Join level: applies the hint whenever the join is used in the query.
- Evaluate: allows the report developer to include a hint, but can't control where Analytics decides to apply the hint.
I propose another method for the report developer to apply hints, when needed, that uses join level hints. All the report developer
does is add the hint column to the Answer or add a filter based on the hint column to the Answer to apply the hint.
Setup
NOTE: I suggest you do consistency checks along the way, especially before starting work in the next Layer, to be sure that all setup errors are resolved early.
1) Start by defining a Logical SQL table in the Physical Layer using the following SQL: Select 1 Hint from dual
2) Alias this table for each hint to be defined for report developer usage. As an example, alias the hint table, creating
No Star and Parallel alias tables.
3) Join each alias to the physical layer fact tables, using a complex join, where the hint could be applied. In the Join definition screen, put the hint in the HINT field and enter 1=1 for
in the Expression section. Yes, we are creating a cartesian join between the hint and the other joining table. As the hint table always returns one and only one row, there
is no effect on the rows returned by the query. For No Star, you
put NO_STAR_TRANSFORMATION in the Hint field. For Parallel, you put PARALLEL(<physical table name>, default, default), where the physical table name
is the name of the actual database table, not the name of the alias table (Analytics will put the alias in the place of the database table name
when it generates the SQL). Additionally, for hints that have no parameters, you only need to join it
to the Fact tables in a query and not necessarily the dimensions. If you include fields from multiple fact tables, the hint will be applied
for each fact table. So, you may see the hint multiple times in the SQL (something like SELECT /*+ NO_STAR_TRANSFORMATION NO_STAR_TRANSFORMATION */ t00001.col1...)
4) Add the hint alias tables to the BMM Layer.
5) Rename the Hint field in each of the BMM hint tables to identify the hint being applied. For No Star, change the column name from Hint to No Star Hint. For Parallel,
change the column name from Hint to Parallel Hint.
6) Set the hint column as a key.
7) Join the BMM hint tables to the appropriate fact tables, using a complex join.
8) Define each hint table as a dimension.
9) Set the Logical Level in the Content tab in each of the sources of the joined tables to use the Detail of the hint dimension.
10) Create a folder in the Presentation Layer called Hints
11) Place each BMM hint field into the Presentation Layer Hints folder.
To apply a hint to your Answer, either add the Hint field to your Answer or create a filter where the Hint field is equal to/is in 1 (the number one). Check that the SQL generated
contains the hint, in Answers, go into Administration, Session Manager, and view the log for the user (the user log level will need to have been set to 7 to see the SQL generated).
Use of hints in more complex setups can be done by performing a setup of the hints that is parallel to the fact table setup. As an example, if you specify fragmentation content and a where
clause in your BMM for your fact tables, you would setup parallel physical layer hint tables and joins, BMM objects and joins, fragmentation content, and where clauses based on the
hint tables (only hint tables are referenced in the where clause).
As any database person knows, hints can either help or degrade the performance of queries. So, taking the SQL of the pre-hint Answer and figuring out which hints give the best
performance is suggested, prior to adding the hint fields/filters to the Answer.

THE QUESTION.
Which (and where) query hint do I use to get the FIRST query to use the execution plan "method" of the second -
IE: To still perform well when a IN-LIST is used instead of EQUALS.
Technical:
Oracle 10.2.0.2 EE on Solaris 8, 64 bit.

What also makes it difficult to read is the lack of formatting tags ([code][/code] or [pre][/pre]) so that we can actually read the code and execution plans.
I'm not going to trawl through formatting all that myself just to try and see what the differences are between query 1 and query 2.
Also bear in mind that when query 2 ran, the data may have been cached and so there is less physical I/O required.
You don't really want to use any hints to cause re-use of execution plans from 1 query to a different query (like I said, I don't know how different they are). What you want to do is determine what poor SQL coding is making the first query slow and fix it.
