Dear All
I want to use create table command in my database .I want access partitioned table of remote datbase thru database link.Pl let me know the scripts.
Thanks

Accessing large partitioned tables over a database link - any gotchas?

Hi,
We are in the middle of a corporate acquisition and I have a question about using database links to efficiently access large tables. There are two geographically distinct database instances, both on Oracle 10.2.0.5 sitting on Linux boxes.
The primary instance (PSHR) contains a PeopleSoft HR and Payroll system and sits in our data centre.
The secondary instance (HGPAY) runs a home grown payroll application and sits in a different data centre to PSHR.
The requirement is to allow PeopleSoft (PSHR) to display targeted (one employee at a time) payroll data from the secondary instance.
For example in HGPAY
CREATE TABLE MY_PAY_DATA AS
SELECT TO_CHAR(A.RN, '00000000') "EMP" -- This is an 8 digit leading 0 unique identifier
, '20110' || to_char(B.RN) "PAY_PRD" -- This is a format of fiscal year plus fortnight in year (01-27)
, C.SOME_KEY -- This is the pay element being considered - effectively random
, 'XXXXXXXXXXXXXXXXX' "FILLER1"
, 'XXXXXXXXXXXXXXXXX' "FILLER2"
, 'XXXXXXXXXXXXXXXXX' "FILLER3"
FROM ( SELECT ROWNUM "RN" FROM DUAL CONNECT BY LEVEL <= 300) A
, (SELECT ROWNUM "RN" FROM DUAL CONNECT BY LEVEL <= 3) B
, (SELECT TRUNC(ABS(DBMS_RANDOM.RANDOM())) "SOME_KEY" FROM DUAL CONNECT BY LEVEL <= 300) C
ORDER BY PAY_PRD, EMP
HGPAY.MY_PAY_DATA is Range Partitioned on EMP (approx 300 employees per partition) and List Sub-Partitioned on PAY_PRD (3 pay periods per sub-partition). I have limited the create statement above to represent one sub-paritition of data.
On average each employee generates 300 rows in this table each pay period. The table has approx 180 million rows and growing every fortnight.
In PSHR
CREATE VIEW PS_HG_PAY_DATA (EMP, PAY_PRD, SOME_KEY, FILLER1, FILLER2, FILLER3)
AS SELECT EMP, PAY_PRD, SOME_KEY, FILLER1, FILLER2, FILLER3 FROM MY_PAY_DATA@HGPAY
PeopleSoft would then generate SQL along the lines of
SELECT * FROM PS_HG_PAY_DATA WHERE EMP = ‘00002561’ AND PAY_PRD = ‘201025’
The link between the data centres where PSHR and HGPAY sit is not the best in the world, but I am expecting tens of access requests per day rather than thousands, so I believe the link should have sufficient bandwidth to meet the requirements.
I have tried a quick test on two production sized test instances and it works in that it presents the data, when I look at the explain plan I can see that the remote database is only presenting the relevant sub-partition over to PSHR rather than the whole table. Before I pat myself on the back with a "job well done" - is there a gotcha that I am missing in using dblink to access partitioned big tables?

Yes, that's about right. A lot of this depends on exactly what happens in various "oops" scenarios-- are you, for example, just burning some extra CPU until someone comes to the DBA and says "my query is slow" or does saturating the network have some knock-on effect on critical apps or random long-running queries prevent some partition maintenance operations.
In my mind, the simplest possible solution (assuming you are using a fixed username in the database link) would be to create a profile on HGPAY for the user that is defined for the database link that set a LOGICAL_READS_PER_CALL value that was large enough to handle any "reasonable" request and low enough to quickly kill any session that tried to do something "stupid". Obviously, you'd need to define "stupid" in your environment particularly where the scope of a "simple reconciliation report" is undefined. If there are no political issues and you can adjust the profile values over time as you encounter new reports that slowly increase what is deemed "reasonable" this is likely the simplest approach. If you've got to put in a change request to change the setting that has to be reviewed by the change control board at its next quarterly meeting with the outsourced DBA vendor, on the other hand, you could turn a 30 minute report into 30 hours of work spread over 30 days. In the ideal world, though, that's where I'd start.
Getting more complex, you can use Resource Manager to kill queries that run too long on the wall clock. Since the network is almost certainly going to be the bottleneck, it's probably unlikely that the CPU throttling is going to do much good-- you can probably saturate the network with a very small amount of CPU. Network throttling in my mind is an extra step up in complexity again depending on the specifics of your particular situation and what you're competing with.

How to test issue with accessing tables over a DB link?

Hey all,
Using 3.1.2 on XE, I have a little app. The database schema for this app only contains views to the actual tables, which happen to reside over a database link in a 10.1.0.5.0 DB.
I ran across an issue where a filter I made on a form refused to work (see [this ApEx thread| http://forums.oracle.com/forums/message.jspa?messageID=3178959] ). I verified that the issue only happens when the view points to a table across a DB link by recreating the table in the local DB and pointing the view to it. When I do this, the filter works fine. When I change the view back to use the remote table, it fails. And it only fails in the filter -- every other report and every other tool accessing the remote table via the view works fine.
Anyone know how I can troubleshoot this? For kicks, I also tried using a 10.2.0.3.0 DB for the remote link, but with the same results.
TIA,
Rich

Rich,
I searched metalink for your issue. This may be a bug in 3.1 which will be fixed in 4.0. Please see Doc ID 740581.1 Database Link Tables Do NoT Show Up In Table Drop Down List In Apex. There is a workaround mentioned in the document.
I'm not sure why I never thought of searching MetaLink, but thanks for the pointer! It doesn't match my circumstances, however. The Bug smells like a view not being queried in the APEX development tool itself -- i.e. the IDE's coding needs changing, not necessarily those apps created with the IDE.
I'm working on getting you access to my hosted app...
Thanks,

Remote Delta link setup problem with Bean / Access Service

Hello,
I am trying to setup Remote Delta Link (RDL) between two portals. (Both portals same version - EP 7.0 EHP1 SP 05 - are in the same domain)
I already have the Remote Role Assignment working without any issues.
The following have been done successfully:
1. Same user repository has been setup for both the portals
2. Setup trust between producer and consumer (SSO working fine)
3. Producer added and registered succesfully on consumer
4. Permissions setup on producer and consumer
4. pcd_service user with required UME actions setup
I am able to see all the remote content in the Consumer portal.
When I try to copy the remote content and paste it as local content, I am getting the following error:
Could not create remote delta link to object 'page id'. Could not connect to the remote portal. The remote portal may be down, there may be a network problem, or your connection settings to the remote portal may be configured incorrectly.
After increasing the log severity, I am able to see the following in Default Trace:
com.sap.portal.fpn.transport.Trying to lookup access service (P4-RMI) for connecting to producer 'ess_int' with information: com.sap.portal.fpn.remote.AccessServiceInformation@31c92207[connectionURL=hostname.mycompany.com:50004, shouldUseSSL=false, RemoteName=AccessService]

AbstractAdvancedOperation.handleDirOperationException
[EXCEPTION]
com.sap.portal.pcm.admin.exceptions.DirOperationFailedException: Could not retrieve the bean / access service to connect with producer
Could not retrieve the bean / access service to connect with producer
Like you can see above, there is some bean / access service which is not retrieved successfully. I am not sure if this is a permission problem on the consumer.
I have checked that the P4 ports are configured correctly (standard - not changed) and I am able to telnet from producer to consumer (and vice versa) on the P4 port.
I am stuck at this point and am not able to find any information on this.
I would really appreciate if some one can point me in the right direction.
Thank you for reading.

Hi Raj,
Please check your config of the P4 port on the producer. Is it really 50004 (check SystemInfo of the producer)?
I do think there's a problem with the P4 communication since RDL requires P4 connection.
Do you have load balanced consumer-producer connection? Please refer to this blog for further details

Linking Java to Access Database tables

Hello,
I need use JCreator to link Java to Access Database tables.
Could any one tell me what kind of drivers I need use?
Also, where could I find the examples of linking Java to Access Database tables?
Thank you,
Daniel

Thanks.
I have read the tutorial and downloaded the sample code from the web http://java.sun.com/docs/books/tutorial/jdbc/
In the CreateCoffee.java programming, I made the following changes:
     //     String url = "jdbc:mySubprotocol:myDataSource";
          String url = "jdbc:odbc:DB1";
DB1 is an Access Database file located in the same folder as CreateCoffee.java.
//Class.forName("myDriver.ClassName");
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Every time when I run the CreateCoffee.java programming, it shows the following running error:
SQLException:[Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified.
Could any one have any suggestions for solving the above problem?
Thank you,
Daniel

Can't use filter when accessing hana table through link from another table in sapui5

Hi all,
Have a strange one and I was wondering if someone had come across this before.
Hana table structure
      entity SalesOrder {
    key element name : String;
    element contact : Association[0..*] to Contact via backlink order;
entity Contact {
element location: Location;
    element order : Association to SalesOrder;
==
each sales order has a number of contacts.
In javascript, if I bind on list of contacts directly then I can use the filter
oRowRepeater.bindRows("/Contact",oRowTemplate,null,[new sap.ui.model.Filter("location",sap.ui.model.FilterOperator.EQ, "Germany")]);
and if I enter link i returns the number of entries
Contact/$count?$filter=location eq 'Germany'
But if I get contacts through the sales order it doesn't allow me to use the filter,
oRowRepeater.bindRows("/SalesOrder('mike')/Contact",oRowTemplate,null,[new sap.ui.model.Filter("location",sap.ui.model.FilterOperator.EQ, "Germany")]);
I can return the contacts same as accessing them directly and i can get the information such as
new sap.ui.commons.TextView({text: "{location}"}) same as before but only difference is that i can't filter.
When I try the following I get error
/SalesOrder('mike')/Contact/$count?$filter=location eq 'Germany'
Error
"message": {
            "lang": "en-US",
            "value": {
                "type": "ODataInputError",
                "message": "Bad Request URL: U"
When I open Chrome Developer Tools I see the following error
SalesOrder/contact/$count?$filter=location%20eq%20%27EMEA%27 400 (Bad Request)
Basically the $count doesn't work if you access contacts indirectly even though the link is there.
Is this a bug or am I doing something wrong?
Hana is sp8, I am up to date with almost everything.
Many thanks,
Matthew

for the reading/writing from oracle to access, you could do something like this:
for table in oracle/access with fields of id(number), name(varchar/text):
Connection oconn = //connect to Oracle
Connection aconn = //connect to access
//create the insert statement into access table
PreparedStatement apstmt = aconn.prepareStatement("INSERT INTO accesstable (id, name) values (?,?)");
//select all the results neeed from oracle table
Statement ostmt = oconn.createStatement();
ResultSet rs = ostmt.executeQuery("select id, name from oracletable where...");
while ( rs.next() )
     apstmt.setLong(1, rs.getLong(1));
     apstmt.setString(2, rs.getString(2));
     apstmt.addBatch();
     //if your driver doesn't support batching, just use this:
     //apstmt.executeUpdate();
//use this only if you use batch statements
apstmt.executeBatch();
rs.close();
stmt.close();
apstmt.close();
oconn.close();
aconn.close();

TIME_OUT in SAP when accessing external Oracle table thru native SQL

Hi,
I have a problem in one of my native SQL statement. It takes a long time accessing the table considering that the number of records to be retrieved is only small.
Something happened on the Oracle system. But, stilll to be confirmed. Before, there wasn't any issue. Looking further, I found that when the value in the where clause equated is a literal (meaning the value is not declared in DATA or CONSTANTS in the ABAP Program)
Example
1.
EXEC.
WHERE FIELD = '1'
ENDEXEC.
instead of
2.
CONSTANTS: c_1 value '1'.
EXEC.
WHERE FIELD = c_1
ENDEXEC.
i found that when the way of coding is same as Example 1, a time-out error occurs. But when in Example 2, no issue.
Can someone explain this? is their something that could affect SAP with respect to Oracle configuration?
Thanks!

I wonder if you could share the outline of your code to access an external oracle database. I've just been given the assignment to do just that, but don't know where to start.
thx,
Mike DeGuire

"No partition table found" Can't access to my DATA partition

Hello friends! It's happened a catastrophe! Yesterday I was resizing partitions on my hard drive, divided in this way:
1: ext4 containing CHAKRA
2: swap
3: extended
3rd: DATA
And here there were all the other partiotions containing ARCH (/ / var / home)
I decided to delete all partitions of Arch, and to extend the DATA partition with the space available obtained by the elimination of arch ... I have done these steps on chakra, the extended partition was unmounted and free to work, I left my computer on all night without even using it so as not to interfere, but 10 minutes ago I go to check and I discover that my computer is off (do not know why because the battery was attached, maybe electricity went down for a considerable period of time and in any case my battery lasts a very little so it has not resisted until the return of electricity).
I turn my computer on, I sign in it with Chakra and I find out that the extended partition is gone! Partitionmanager tells me "No partition table found" and all my data are disappeared!
Is there a way to remedy this apocalypse? I truly don't know what to do, apart committing suicide!
Last edited by TheImmortalPhoenix (2012-01-18 05:30:20)

There is no drive! There is only free space, and all i can do is to create a new partition...

ORA-28150 when accessing data from a remote database

Portal Version: Portal 3.0.9.8.0
RDBMS Version: 8.1.6.3.0
OS/Vers. Where Portal is Installed:: Solaris 2.6
Error Number(s):: ORA-28150
I have a problem with using a database link to access a table in
a remote database. So long as the dblink uses explicit logins
then everything works correctly. When the dblink does not have a
username then I get the ORA-28150 message. The database link is
always public. A synonym is created locally that points to a
synonym in the remote database. I am using the same Oracle user
in both databases. The Oracle portal lightweight user has this
same Oracle user as its default schema. The contents of the
remote table are always visible to sqlplus, both when the link
has a username and when it doesn't have a username.
All the databases involved are on the same version of Oracle.
I'm not sure which Oracle login is being used to access the
remote database, if my lightweight user has a database schema
of 'xyz' then does portal use 'xyz' to access the remote
database? I would be very grateful for any help or pointers that
might help to solve this problem.
James
To further clarify this, both my local and remote databases
schemas are owned by the same login.
The remote table has a public synonym.
The link is public but uses default rather than explicit logins.
The local table has a public synonym that points to the remote
synonym via the database link.
If I change the link to have an explicit login then everything
works correctly.
I can view the data in the remote database with TOAD and with
sqlplus even when the database link has default login rather
than explicit login.
This seems to point to Portal as being the culprit. Can anyone
tell me whether default logins can be used across database links
with portal?
TIA

One way to do this is by creating a database link and joining the two tables directly. But this option is ruled out. So please suggest me some way of doing this.Thus you MUST use two connection strings.
Thus you are going to be either constructing some intricate SQL dynamically or you are going to be dragging a lot of data over the wire and doing an in memory search.
Although realistically that is what the database link table would have done as well.
Might be better to look at moving the table data from one database to the other. Depends on size of course.

MS Access attach table error after migration

I ran the MS Access Migration Wizard 1.5.4 to convert an Access
97 Database to Oracle 7.3.3 (soon to be 7.3.4).
Everthing seemed to go ok, the mdb file shows the local and
remote attached tables, the queries are present etc. Also the
ODBC link is fine within the mdb file, in that I can browse the
data on the Oracle database.
However when I start the MS Access application which is in an
mde file, I get the following error :
modRefresh AttachTables Error: The Microsoft Jet database engine
cannot find the input table or query 'tablename'. Make sure it
exists
and that its name is spelled correctly. (3078)
The application continues to work fine if I put the original mdb
file back.
Is anybody able to help identify what the problem is or how to
turn on some debugging that might help. Any help appreciated as
I don't have a lot of experience with Access.
Thanks,
Mike.

Mike,
The Migration Wizard only supports one level of linked
tables.

"ghost records" in partitioned tables

Hi,
We observe a very strange behavior of some partitioned table (range method) for a small subset of records. For example:
select b.obj_id0 from event_session_batch_ctlr_t partition(partition_migrate) b, event_session_batch_ctlr_t c
where b.obj_id0=c.obj_id0(+)
and c.obj_id0 is null
This query returns 20 records where it shouldn't returns anything! obj_id0 is the partitioning key and the primary key of the table.
If you query these line directly from the partitioned table, even with a full scan, you don't get anything back. You will get the data if you query from that particular partition (partition_migrate).
We found that these records can sometimes be returned from a query with a joint on this partitioned table, without specifying any partition name, depending on the execution plan.
Have you some explanation for this strange behavior and suggestions for how to solve this problem?
Thank you in advance,
Raphaël

Hi,
       Retrive those records from backup.So,better u contact basis people.
      RTVDLTRCD   FROMFILE(xxx) TOFILELIB(yyy) - This Command is used to retrive the deleted records.
       This would extract the deleted records in the FROMFILE and write them to the same named file in the library specified for TOFILELIB.
                                      When a record is deleted in a data base file, the data values still exist, but the system places a special hex value in front of the     record specifying that it is deleted.   The Operating System prevents any access to a deleted record thru its normal interfaces.

SolutionThe resolution to this issue depends on the the hard disk volume size:
Follow these steps if the hard disk volume size is less than 2.19 TB:
Temporarily disable the EFI Boot Sources setting in the BIOS:
Restart the computer, and then press F10 to enter the BIOS.
Navigate to Storage > Boot Order , and then disable the EFI Boot Sources .
Select File > Save Changes > Exit .
Install the Windows operating system.
Enable the EFI Boot Sources setting in the BIOS:

I am having the same problem. Windows is trying to install. It identifies the various partitions but says that I cannot install Windows on the Boot Camp partition or any other. I select Drive options (advanced) and Format the Boot Camp drive, but it makes no difference.
This is the Windows error:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer BIOS menu.
I am not sure what Csound1 is suggesting with that post above. There are some involved suggestions over here <https://discussions.apple.com/message/23548999#23548999> about using Disk Utility to delete the Boot Camp partition and create new ones - is that the idea?

How to partition tables and indexes in this scenario?

So our situation is pretty simple. We have 3 tables.
A, B and C
the model is A->>B->>C
Currently A, B and C are range partitioned on a key created_date however it's typical that only C is every qualfied with created date. There is a foreign key from B -> A and C -> B
we have many queries where the data is identified by state that is indexed currently non partitioned on columns in A ... there are also indexes on the foreign keys that get from C -> B -> A. Again these are non partitioned indexes at this time.
It is typical that we qualify A on either account or user or both. There are indexes (non partitioned) on these
We have a problem now because many of the queries use leading wildcards ie. account like '%ACCOUNT' etc. This often results in large full table scans. Our solution has been to remove the leading wildcard but this isn't always possible.
We are wondering how we can benefit from partitioning and or sub partitioning table A. since it's partitioned on created_date but rarely qualify by that.
We are also wondering where and how we can benefit from either global partitioned index or local partitioned indexes on tables A. We suspect that the index on the foreign key from C to B could be a local partitioned index.
I am also wondering what impact pushing the state from A that's used to qualify A down to C would have any advantage.
C is the table that currently we qualify with the partition key so I figure if you also pushed down the state from A that's used to qualify the set of C's we want based on the set of B's we want based on the set of A thru qualfying on columns within A.
If we push down some of those values to C and simply use C when filtering I'm wondering what the plans will look like compared to having to work all the way up from the bottom to the top before it begins qualifying A.

We are wondering how we can benefit from partitioning and or sub partitioning table A. since it's partitioned on >created_date but rarely qualify by that. Very good question. Why did you partition on it? You will never have INSERTS on these partitions, but maybe deletes and updates? The only advantage (I can think of) would be to set these partitions in a read only tablespace to ease backup... but that's a weired reason.
we have many queries where the data is identified by state that is indexed currently non partitioned on columns in >A ... there are also indexes on the foreign keys that get from C -> B -> A. Again these are non partitioned indexes at >this time.Of course. Why should they be partitioned by Create_date?

We have a problem now because many of the queries use leading wildcards ie. account like '%ACCOUNT' etc. This >often results in large full table scans. Our solution has been to remove the leading wildcard but this isn't always possible.I would suspect full index scan. Isn't it?
We are also wondering where and how we can benefit from either global partitioned index or local partitioned >indexes on tables A. We suspect that the index on the foreign key from C to B could be a local partitioned index.As A is not accessed by any partition, why should C and B profit? You should look to partition by the key you are using to access. But, you are looking to tune your SQLs where the access is like '%ACCOUNT' on A. Then when there is a match. ORACLE joins via your index and nested loop (right?) to B and C.
I am also wondering what impact pushing the state from A that's used to qualify A down to C would have any >advantage.Why should it. It just makes the table and indexes larger => more IO.
C is the table that currently we qualify with the partition key so I figure if you also pushed down the state from A >that's used to qualify the set of C's we want based on the set of B's we want based on the set of A thru qualfying >on columns within A.If the access from A to C would be .. AND A.CREATE_DATE =C.CREATE_DATE and c.key like '%what I want%' which does not qualifify for a FK ;-) then, as that could be resulting in a partition scan, you could "profit". But, I'm sure that's not your model.
If we push down some of those values to C and simply use C when filtering I'm wondering what the plans will look >like compared to having to work all the way up from the bottom to the top before it begins qualifying A.So you want to denormalize A,B,C and into one table? With the same access is like '%ACCOUNT' you would get a full scan on an index as before, just the objects would be larger due to redundance and harder to maintain. In the end you would have a bad and slower design.
Maybe you explain what the problem is.
Full index scan can not be avoided, but that can be made faster by e.g. parallel query, and then the join to B and C should be a "snip" if you just identify a small subset of rows in these tables.
