Slow Processing - reconnecting to the database

The response time for SQL Developer for our developers in India is very slow. One observation I've had is that each activity reconnects to the database. Is there a way to establish the connection once and continue working within that connection. That may help the response time for the India developers. Is there other suggestions that might help improve the connectivity and response time for India developers?

I will gather more information from those in India to address your question. From my own experience, whenever I open a new SQL Worksheet to pull in a new procedure which I've typed in text, I get a message of 'Connecting to database'. Then when I close this and go to look at a table, I again get 'Connecting to database'. From my experience, with each new activity I was getting that message. I feel I may have something not set correctly which might be forcing this or I'm not doing a transition from one process to another correctly. I am processing each as the same user.
I am connecting to Oracle 10.2.0.2, operating system of Windows XP, SQL Developer 1.5.2, and JDK or 1.5.0_06, Hardware Intel(R) Core(TM)2Duo CPU, 2.53GHz, 1.99GB of Ram.

How to make toplink reconnect to the Database in java SE

I have use toplink JPA in java SE.
I found a problem with using connection pool in toplink:
If the network connection is disconnect and Even if it is reconnect right away.
Then the connection to the Database can not be use;
So I should restart my java SE application to reconnect to the Database.
How can I make the toplink to reconnect to Database so I need not restart my java SE application
My english is poor. am I clear?
thanks for you help.
merry christmas

TopLink has an ExceptionHandler interface you can implement and register the instance. This allows you to capture the failure when the connection dies allowing you to re-connect it and possibly retry a read query.
What edition and version of TopLink are you running?

Trying to configure syslog process,to write the database audit logs

Folks,
Running Oracle 10g R2 on Sun Solaris v 10.
I am trying to configure my database environment, so it will write all the database audit logs to a location, where Oracle userid on unix cannot modify/delete it.
To accomplish my goal, so far I have done the following:
I have set the following parameter with these values
audit_file_dest /flood/u01/app/oracle/product/10.2.0/db_1/rdbms/audit
audit_sys_operations TRUE
audit_trail OS
Also I asked my system administrator , to make an entry in the syslog.conf file at location /etc
He made the following entry
local3.notice /var/log/oraaudit.log
and restarted the syslog process
I also made the following entry
alter system set audit_syslog_level='LOCAL3.NOTICE' scope=spfile and bounced the database.
But after starting the database, i will don't see any oraaudit.log file at the location /var/log
Any help will be much appreciated.
Regards
Ashish

Hello Srini,
I mentioned in my posting , that I already set AUDIT_SYSLOG_LEVEL=LEVEL3.NOTICE value.
Also the permission on /var/log is such the Oracle unix userid cannot write to it and that is what I want. Since if Oracle userid can write, it can modify/delete the audit log also , which we are trying to prevent.
Thanks
Ashish

Shows follwing error when trying to refresh the database?

Hi All,
When i try to refresh the database its showing the following error.
com.hyperion.planning.HspCubeRefreshInProgressException: Cannot complete your request because the database is being refreshed.
Please let me know ASAP how to reslove the issue.
Cheers,
Kittu.

Looks there is an other process running on the database, you can check from EAS sessions or check logs for other activity running on the application.
If you think that nothing is running & no users logged in, you can try unlock application from planning/essbase outline and try refresh.
But pretty sure that some other activity is running on application, like sec refresh or data load or users trying to retrieve/load...etc...hope this helps.

Reconnect to portal database after database restart

Hi,
After having seen a 24/7 EP system in production for a while, there is one contributing factor which is causing more downtime than we would like (even though the downtime is very small).
When ever the portal database is restarted or we loose the network connection, the SAP J2EE (and hence EP) is not able to reconnect to the database (as you would expect from such a mature product). The forces us to take down the entire cluster (yes the cluster is big and takes a lot of time to restart) and then take it up again.
An OSS has been open (and been through development) and the verdict is that it cannot be done.
However, I don't believe them. Some of you SAP expert here must know of some very cleaver hack to get this working.
If you have any ideas or experience with this, please do not hesitate to post it.

Managed to find some undocumented command that did the trick.
1. Telnet to the administration console (port 50008 is standard ?)
2. Login as administrator
3. Run the lsc command in order to get the cluster id of an application node
4. Change the active node to an application node
>jump <clusterId>
5. Add the dbpool command set
>add dbpool
6. Close the database pool
>close_pool <poolname> -force
7. Open the database pool
>open_pool <poolname>
From the SAP J2EE administration console in the dbpool there seems to be a functionality for closing and opening the pool, but this doesn't work, at least not in PL21 (maybe it doesn't force the connections to close)

Handling in java special characters read from the database

Hello,
I have a java application which processes data from the database. During processing I have to handle some special national characters which are specified with integer codes. The codes are defined in UTF-8 and the list of these characters and their codes is constant.
How to handle them in java where char primitive type denotes characters in UTL-16, not UTF-8. Should I use class Charset and decoder like below?
Charset charset = Charset.forName("UTF-8");
CharsetDecoder decoder = charset.newDecoder();
The problem which I see here is that class CharsetDecoder provides no method which would take integer code of the character in UTF-8 and return char value (in UTF-16).
The only way I see is to provide ByteBuffer, but then I have to encode the codes of these characters in UTF-8 somehow (how?), as they have two bytes codes like 50048.
Best wishes,
Tomasz Michniewski

Please verify the followings:
Make sure that from the SharePoint front end and application servers that you can ping your SQL server.
Make sure that your Farm account has permission to the configuration database.
Lastly verify that your database didn't for some reasons go into recovery mode.
once everything is fine and you are still having issues, restart the SQL host service on the SQL server.
Once the service is restarted you will need to reboot Central Admin and then your front end servers.
In addition, as you built your farm inside the firewall, please disable the firwall, or create rules for SQL Server service in the firwall on SQL server.
More information about creating rules in firewall, please refer to the following posts: http://social.technet.microsoft.com/Forums/en-US/c5d4d0d0-9a3b-4431-8150-17ccfbc6fb82/can-not-create-data-source-to-an-sql-server http://www.mssqltips.com/sqlservertip/1929/configure-windows-firewall-to-work-with-sql-server/

SQL Server Profiler does not capture cube processing queries against the relational database

Hello, experts,
This my first attempt to use SQL Server Profiler to find out why my cube processing is so slow. Here is what I did:
My cube sources its data from a SQL Server database. While the cube processing is going, I launched the profiler connecting to the database engine (note: not the Analysis Services). I choose the "Tuning" template and started the trace. However,
I do not see any query activities (such as, SELECT DISTINCT ...) in the profiler trace window.
Did I do something wrong, or do I have the wrong expectation?
Thank you much in advance.

Hi QQFA,
Agree with Olaf.
Please make sure that you choose the appropriate events to monitor the cube processing queries when using SQL Server Profiler.
And I recommend you review the following links to get more information about tuning Analysis Services with SQL Profiler.

The database and Application is running very slow.

We are facing the slow performance on Application and Database.
We found that the load average is going very high and when we checked through sar , it shows sys is using 70% CPU.
Can some body let me know , how to check that where system is eating the CPU.
through prstat and other i am able to see only the user process.
Please guide me on the same.
Regards

I would suggest you first check and note that PID from prstat that is using 70%. Then query v$session and link it with v$process to see what session owns that PID. That way, you can track the problem down to a particular session and probably code in your application. Then you can further drill down to root cause of it.

I am in the process of expanding a database of chemistry journal articles. These materials are ideally acquired in two formats when both are available-- PDF and HTML. To oversimplify, PDFs are for the user to read, and derivatives of the HTML versions are for the computer to read. Both formats are, of course, readily recognized and indexed by Spotlight. Journal articles have two essential components with regards to a database: the topical content of the article itself, and the cited references to other scientific literature. While a PDF merely lists these references, the HTML version has, in addition, links to the cited items. Each link URL contains the digital object identifier (doi) for the item it points to. A doi is a unique string that points to one and only one object, and can be quite useful if rendered in a manner that enables indexing by Spotlight. Embedded URL's are, of course, ignored by Spotlight. As a result, HTML-formatted articles must be processed so that URL's are openly displayed as readable text before Spotlight will recognize them. Conversion to DOC format using MS Word, followed by conversion to RTF using Text Edit accomplishes this, but is quite labor intensive.
In the last few months, I have added about 3,500 articles to this collection, which means that any procedure for rendering URL's must be automated and able to process large batches of documents with minimal user oversight. This procedure needs to generate a separate file for each HTML document processed. Trials using Automator's "Get Specified Finder Items" and "Get Selected Finder Items", as well as "Ask For Finder Items" (along with "Get URLs From Web Pages") give unsatisfactory results. When provided with multiple input documents, these three commands generate output in which the URLs from multiple input items are merged into a single block, which yields a single file using "Create New Word Document" as the subsequent step. A one-to-one, input file to output file result can be obtained by processing one file at a time, but this requires manual selection of each item and one-at-a-time processing. What I need is a command that accepts multiple input documents, but processes them one at a time, generating a separate output for each file processed. Is there a way for Automator to do this?

Hi,
With the project all done, i'm preparing for the presentation. Managed to get my hands on a HD beamer for the night (Epason TW2000) and planning to do the presentation in HD.
That of course managed to bring up some problems. I posted a thread which i'll repost here . Sorry for the repost, i normally do not intend to do this, but since this thread is actually about the same thing, i'd like to ask the same question to you. The end version is in AfterEffects, but that actually doesn't alter the question. It's about export:
"I want to export my AE project of approx 30 min containing several HD files to a Blu Ray disc. The end goal is to project the video in HD quality using the Epson EMP-TW2000 projector. This projector is HD compatible.
To project the video I need to connect the beamer to a computer capable of playing a heavy HD file (1), OR burn the project to a BRD (2) and play it using a BRplayer.
I prefer option 2, so my question is: which would be the preferred export preset?
Project specs:
                    - 1920x1080 sq pix (16:9)
                    - 25 fps
                    - my imported video files (Prem.Pro sequences) are also 25 fps and are Progressive (!)
To export to a BRD compatible format, do i not encounter a big problem: my projectfiles are 25 fps and progressive, and I believe that the only Bluray preset dispaying 1920x1080 with 25 fps requests an INTERLACED video (I viewed the presets found on this forum, this thread)... There is also a Progr. format, BUT then you need 30 fps (29,...).
So, is there one dimension that can be changed without changing the content of the video, and if yes which one (either the interlacing or the fps).
I'm not very familiar with the whole Blu-ray thing, I hope that someone can help me out."
Please give it a look.
Thanks,
Jef

Errors in the OLAP storage engine: An error occurred while processing the indexes for the partition of the measure group of the cube from the database.

Errors in the OLAP storage engine: An error occurred while processing the indexes for the partition of the measure group of the cube from the database.
I have dropped and recreated a fact table to refresh the data as the table is having identity columns. So not able to directly insert data. After that cube is throwing above error.
Please suggest.

Hi Md,
It hard to analyse the issue base on the limited information, Are there any error message on the log? Under C:\Program Files\Microsoft SQL Server\MSAS11.\OLAP\Log (this could be different for your server), there are 3 log files that are generated:
msmdrrv.log
FlightRecorderCurrent.trc
FightRecorderBack.trc
The msmdrrv.log simply points to the other two logs. There might be some detail information for this error. Please provide us the detail information about it, so that we can make further analysis.

Process exist in apps server but not in the database

Hi all,
10.2.0.3 2 node RAC AIX
In our application server,topas command shows some PIDs consuming high CPU. But the PID when resolved to sid in the database,no rows are returned.
Which means the process does not exist in the database.
How can I know what the process is doing in application server as it has gone zombie now?
Thanks

Hi,
There are some cases when a transparent table exists in the Data Dictionary but not in the database.
1. You have just created the table and saved it. But you have not activated it.
2. There's a large amount of data in your table and you have attempted to change the key fields of the table (e.g., you are trying to delete existing key fields). This action requires you to use the database utility. During this process, the table is first physically deleted from the database and a new table is created. In the meanwhile the data from the old table is stored in a temporary table. So while the database utility is performing this operation, the table does not exist in the database for some time.
Hope this helps.
Regards,
Anand Mandalika.

Automating the installation process,creating the database, creating tables etc at the

Hi,
We have a requirement to install oracle 8.1.6 on solaris box. The whole installtion process should be automated. This process includes changing the kernel parameters, creating the oracle account as per the installation guide, configuring the logical volumes, creating the database as per OFA recommendations, creating tables etc. How can i do this with out any interaction from user. Can the Oracle software packager handle all these. Please Let me know ASAP.
Thanks a bunch.

Agata,
The full retail should be white with a snow leopard on it but if you ordered from the on-line store you should be fine. If it is having problems booting while holding the C key, try restarting the computer but this time hold the Option key.
That will bring up a grey screen with the image of the Macintosh HD and an image of the CD. Click the image of the CD and let it boot that way.
Once booted, go through the install proceedure, choose language, etc. Still using the same CD but let's see if for some reason it does not like the way it is being told to boot.
