Distributed Queries - Index Server

Using Kodo, is it possible to perform distributed queries. that is to
combine a standard tabular SQL query and one which queries an index server?
I suppose the real question is, is it possible to query a full text index
using Kodo?

Kodo doesn't provide any built-in support for querying a separate
server for a particular JDOQL query. If the index server has a JDBC API,
then it wouldn't be too difficult to issue the query using a separate
PMF for the index server, and then manually join the results to get back
the appropriate objects from the main database.
There are also a bunch of interesting things you can do with custom
field/class mappings; you might want to investigate these APIs
(preferrably in 3.0, where they are more sophisticated).
Finally, the next release of 3.0 will contain a new "textindex" sample,
which demonstrates how you might roll your own full text index purely in
JDO.

Facing problem in distributed queries over Oracle linked server

Hi,
I have a SQL Server 2005 x64 Standard Edition SP3 instance. On the instance, we had distributed (4 part) queries over an Oracle linked server running fine just a few hours back but now they have starting taking too long. They seem to work fine when OPENQUERY
is used. Now I have a huge number of queries using the same mechanism and is not feasible for me to convert all queries to OPENQUERY, please help in getting this resolved.
Thanks in advance.

Hi Ashutosh,
According to your description, you face performance issues with distributed queries and
it is not feasible for you to convert all queries to
OPENQUERY. To improve the performance, you could follow the solutions below:
1. Make sure that you have a high-speed network between the local server and the linked server.
2. Use driving_site hint. The driving site hint forces query execution to be done at a different site than the initiating instance.
This is done when the remote table is much larger than the local table and you want the work (join, sorting) done remotely to save the back-and-forth network traffic. In the following example, we use the driving_site hint to force the "work"
to be done on the site where the huge table resides:
select /*+DRIVING_SITE(h)*/
ename
from
tiny_table t,
huge_table@remote h
where
t.deptno = h.deptno;
3. Use views. For instance, you could create a view on the remote site referencing the tables and call the remote view via the local view as the following example.
create view local_cust as select * from cust@remote;
4. Use procedural code. In some rare occasions it can be more efficient to replace a distributed query by procedural code, such as a PL/SQL procedure or a precompiler program.
For more information about the process, please refer to the article:

Linked Server and Distributed Queries in Oracle

In MSSQL, Linked Server and Distributed Queries provide SQL Server with access data from remote data sources. How about in Oracle ?
I have a table A at Server A and table B at Server B, i wanna join these two table together. How can i do this in Oracle ?

Use a database link: http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm
For instance, if you have created on database A a link to database B with name 'database_b'
you can use
select * from table@database_b

Xml data type is not supported in distributed queries. Remote object 'OPENROWSET' has xml column(s).

HI ,
1. You cannot use a table or view that contains xml or clr type as 4-part name in your query
2. You need to cast the column to either nvarchar(max) or varbinary(max) or other appropriate type to use
3. If you have a table that has xml type for example then you need to create a view that contains all columns other than xml and query it instead. Or you can issue a pass-through query using OPEN QUERY with the appropriate columns only.
Here is a work around:
SELECT
Cast(a.XML_Data as XML) as XML_Data
FROM
OPENQUERY([LINKED SERVER NAME HERE],'
SELECT
Cast(XML_Data as Varchar) as XML_Data
FROM
[DATABASE NAME].[SCHEMA].[TABLE NAME]'
) a
Basically, the data is queried on the remote server, converts the XML data to a varchar, sends the data to the requesting server and then reconverts it back to XML.
You can take help from below link;

OLE DB provider 'MSOLAP' cannot be used for distributed queries because the provider is configured to run in single-threaded

Hopefully this will save somebody some trouble.
Running 64bit Enterprise SQL and SSAS with Service pack 2 installed.
Also running Proclarity so 32bit mode Reporting Services is running.
When trying to create a linked server to my OLAP database I was continually getting the following Error:
OLE DB provider 'MSOLAP' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode. (Microsoft SQL Server, Error: 7308)
Many posts suggested I select the "in Proc" check box under the olap provider, but this did not help.
Finally, instead of using the IDE to create the linked server I used a script to call sp_addlinkedserver and used @provider='MSOLAP.3'. This fixed the problem.
If you have a more clear idea of why I was having the issue in the first place, feel free to let me know what you think.

Check here to see how to add servers to the farm:
http://technet.microsoft.com/en-us/library/cc261752(v=office.15).aspx
What Inderjeet meant was that if you chose to install SharePoint as a single server instead of a complete farm, you won't be able to add servers to the farm at a later time. You can check if this is the case by checking the registry key he mentioned. If
that is indeed the case, there's nothing to it but reinstall the farm.
So that is why you never should choose the single server option, it locks you in and limits future options, while choosing to install sharepoint as a complete farm it's still perfectly acceptable to host it on a single server.

How to deal with Short dump that restarts the index server?

Hi ,
I have been experiencing this problem whenever any exception occurs in my SQL SCRIPT procedure. For instance when there is a situation when I try to insert a value of 50 characters in length to a column with max size of 40 it throws a short dump and restarts the index server. I tried to insert the exception handling code as well but still the problem persists. Is there a way to solve this issue?

Hi Sudarshan
crashes are rather generic reactions of the system to virtually any kind of problem that may occur.
Memory shortage is one of the more common issues in current SAP HANA setups and SAP HANA development is heavily working on handling memory shortage situations more gracefully.
Massive over allocation of memory, for example by very large intermediate result sets or join result sets typically can be addressed by correcting the query or model that leads to the issue.
Anyhow, the initial post was not about a memory shortage but about a crash that seemed to have occurred with wrong data type handling.
These are two very different kinds of problems, so I am not really sure how your comment relates here.

The Index Server is in Read Only Mode

has anybody seen this before, and how can I correct it?
Thanks,Shawn

The search server goes into read only mode in response to certain error conditions. Simply restart the service to put the search server back into R/W mode. The server will attempt to self repair on startup. You should review your recent search server logs to see if there are errors that may have caused the transition to read only mode. If problems persist, contact tech support for further assistance in troubleshooting.

"Error 75 received from the Package Index Server. Please contact the Support Center"

I have a T-61P running Windows XP SP2. Within the past month, my System Updater started returning
"Error 75 received from the Package Index Server. Please contact the Support Center"
I uninstalled System Update and downloaded and installed again from the Lenovo site. Still displays same error message. I get 20% into the update when the error message pops up.
Any suggestions.
Thank You!

They should be in the form of your model number without the hyphen and not TP-xx___
In my case I had to change the TP-71___ that was showing in my registry to 87445BU. Once I did this the software worked without a hitch.

HANA Index Server Not Starting

Hi,
We are using SAP HANA Rev 48 on AWS. HANA Server got crashes and Index server is not starting. Looking at Crash Logs (Attached), seems HANA Memory Usage is close to Allocated Memory.
How can we resolve this. We may be fine to unload tables or delete some of the data to make the system up and running but unable to perform actions as for these DB need to start once.
Any suggestions.
Thanks,
S

Hi Shobhit,
If I follow your original message correctly, you are using HANA One Rev 48. Then, if you follow https://scn.sap.com/docs/DOC-59814, you will see HANA One Rev 48 was released on Feb-7-2013 which came with 1 year license. So, your HANA license key delivered via HANA One Rev 48 must have expired now.
There were multiple messages, blogs posted requesting existing HANA One customers to migrate to HANA One Rev 52.1. Here is one such blog:http://www.saphana.com/community/blogs/blog/2013/09/26/sap-hana-one-migration-via-data-backup-and-recovery. The blog says -
"SAP released HANA One Rev 38, HANA One Rev 48 and HANA Rev 52 prior to the releasing HANA One Rev 52.1. HANA One Rev 52.1 has self-service upgrade capability via Addon Manager [blog]. Customers using HANA One Rev 52.1 can continuously upgrade to the latest HANA version as a self-service option and can also extend 1 year license key at its expiry or install a valid license key, if needed. However, customers using HANA One prior to HANA One Re 52.1, cannot upgrade HANA nor can extend license key. This blog provides a step by step procedure to migrate older releases of HANA One to the latest HANA One to take advantage of new Addon feature in HANA One Rev 52.1."
It appears you haven't upgraded your HANA version from Rev 48. I believe HANA One Rev 52.1 supports HANA Rev 72 as I write now.
As a good practice for any database, you should take periodic backup to meet your business requirements. I see you don't have backup.
If this is extremely urgent to recover your system, you may contact HANA One team at [email protected] with valid business justification why you may need a temporary license to recover your system and then you can migrate to the latest HANA version delivered via HANA One.
Thanks,
Swapan Saha
P.S. I have new responsibility at SAP and hence not following HANA One messages regularly. Just responding here due to the uniqueness of the issue. However, community members and my HANA One colleagues are regularly following up here. So, once you resolve HANA License key issue, you can resolve related issues with community support here. Please keep using HANA One and sharing your knowledge wih fellow community members.

Distributed queries+pipelined table function

HI friends,
can i get better performance for distributed queries if i use pipelined table function.I have got my data distribued across three different databases.
thanx
somy

You will need to grant EXECUTE access on the pipelined table function to whatever users want it. When other users call this function, they may need to prefix the schema owner (i.e. <<owner>>.getValue('001') ) unless you've set up the appropriate synonym.
What version of SQL*Plus do you have on the NT machine?
