after uninstalling 10g software with home using universal installer how to re-install without deleting all components of database like the database exists i just want to put the oracle software on it and reusing x home location.
I have a Oracle 11g R2 XE installed in my PC. I also have a licensed VB2010 Ultimate(free from class). I have made three systems using this database, 1 using php and 2 using .net.
My question is, if I uninstalled my database and then reinstall it, will it affect my the systems I made(I already backed-up my tables etc.)?
for example, the components for my oracle-vb connection.Why I need to uninstall? Because I got locked out of the System account:, I can't change my password.

steps to export/import a database with options with exp/imp command.i want to acess the exported database table with my current user schema, means actually i had exported a database earlier but i'm not able to access tables directly rather i've to use exported database schema like abc.tablename.
My question is; I've been reading the Oracle database 11g R2 documentation at this link [URL]...
I passed a couple of days learning about all installation configuration parts including the desktop class and server class.As I was learning, So I had already downloaded Oracle Database Express 11g R2 for win32.
So as i had finished the installation guide I thought it's time to install the oracle now. I did it, and what I found was that there was not any option during installation that i read in above documentation. While trying to find about this difference i reached on documentation[URL]...
That is for express version only.
My question here is, Express edition, we use for learning purpose, But it doesn't look like it has all the stuff that we should learn during installation And what documentation I should follow from my above given two links?
I downloaded the 11G 64bit for windows and unzipped the files into one folder and ran the setup.exe as an administrator. It opened up the java screen and I chose, create and configure a database. Next screen I chose, Desktop Class, when I click next it dies. It does not show me teh next screen. I went to the appdata folder and saw this error but not sure what to do EXCEPTION_ACCESS_VIOLATION (0xc0000005).
I would like to check and make sure that features like partitioning, Tuning, Diagnostics etc. have NOT been used. In Oracle 10 + we have the dba_feature_usage_statistics.
I have a windows server 2008 machine and I have installed the oracle client win64_11gR2_client and I need to uninstall it. It does not appear in the program list and there is no uninstall in the Oracle menu items. I need to uninstall this client. How do I do that?
I got a couple of reports that are made as .CSV files from PL/SQL. However I am lacking some design features. Is it possible to define text + background color and height + width of fields? (I am using utl_file package.)
What are the default features available along with 10g R2 Enterprise Edition , Especially for RMAN Backup ? What are the features required for licensing in 10g R2 EE version .
I read previous post "Can I use the latest features in Oracle Developer Tools 11g and still use ODP.NET version 10.x or 9.x in my application?".In this the solution was: "Solution: Yes, you can use the newest 11g version of Oracle Developer Tools while developing code that relies on ODP.NET version 10g or 9i. In almost all cases it will work fine. The only exception is with the automatic .NET code generation feature. Here is what you need to do:
a) Install both ODT 11g *and* ODP.NET 10g or 9i. They must be placed in different Oracle Homes! b) You will now be able to use the 11g Oracle Developer Tools for Visual Studio and all of the newest features. To ensure the correct version of ODP.NET is used by your application continue to the next steps: c) Make sure that in the "References" section in your solution, the Oracle.DataAccess.dll that is referenced is coming from the Oracle 10 or Oracle 9 Oracle home. d) Finally, you must "ungac" (gacutil /u) the ODP.NET 11g policy DLL's or else your application will silently begin using the 11g version of ODP.NET even though the reference points to the correct DLL. There are several Oracle policy DLLs with varying names, for example: "Policy.2.102.Oracle.DataAccess.dll". Ungac them all."
Are the steps the same if i have Oracle Developer Tools 12c and still use ODP.NET version 11g R2 in my application?
I have installed Oracle 11g XE with Apex 4.2 and I want to upgrade it to the apex 4.2.2. However, I do not have access to My Oracle connect. How do I uninstall apex 4.2 and install apex 4.2.2 full version from OTN?
I am working on an assignement where client is using Oracle 10g but stuck to using RBO Now the application team, from the GUI available to them build dynamic queries and some of them run very slow.
Neither the code can not be changed to tune the queries nor do we get the exact step in the plan which is an issue (being RBO).For some long running queries the Tuning advisor is not producing any recommendations.
Another hurdle is that all the application users are using same application user id so we can not write a logon trigger to use CBO for some particular queries to see what is happening in the background!
I had one of my RAC nodes go down due to a disk failure. I have a 3 node cluster running 10.2.0.4 on Dell 610's running Windows Server 2008. I have been running AWR reports this afternoon and am seeing CPU time as my top timed event. Here is the exerpt from the report I am looking at:
Cache Sizes ~~~~~~~~~~~ Begin End ---------- ---------- Buffer Cache: 20,032M 20,032M Std Block Size: 8K Shared Pool Size: 12,688M 12,688M Log Buffer: 6,336K
[code]...
I wanted to ask if there was anything that I could be doing to alleviate the workload on the 2 remaining nodes right now? As far as I understand it there is no way to stop users from hitting the database and without my 3rd node to load balance the CPU will continue to be pegged until the end of the day as the users are logging off.
I have a production DB that has the oracle tuning pack option turned on, I occasionally need to clone the DB to a test server where I do not use the tuning pack, If I select from DBA_feature_usage_statistics it tells me that the Options pack is turned on for the Prod db DBID but not for the cloned db dbid. Do I need to worry about this old data being left around in my database? If so is there anyway to remove it? I am running 10.2.0.4
We have a table with huge data which is skewed on a 'status' column. The 'status' column has 6 distinct values with 1 particular value occupying 80-85% records.
In the batch process we query the data on the status and process the retrieved records. My senior is insisting on partitioning which I see not much feasible considering cost implications just for a part of functionality
See there are 6 status 'A','B','C','D','E','F'
with 'A' occupying 80% records 'B' to 'F' occupies 2% till 14% records in the table(approx)
1) Create a conditional index on status (using case) to have records with all statuses except 'A' Then create If-ELSE structure
IF input parameter is 'A' select /*+ FULL Parallel(t) */ * from t where status='A'; ELSE Select /*+ INDEX (t conditional_index) */ * from t where status in ('B','C'); END IF;
I want to create conditional index here for 2 reasons
1] since it will have values for status except 'A' this nullify the chance that this index will be picked up when status='A' will be queried Thus making the performance worst (status ='A' is for 80% records) - The IF-ELSE is additional protection 2] Less impact on the DMLS as the index will not be on status='A' which contribute to large chunk of records
2)Populate a dummy table which would contain rowid and status. Since the business closes at 21:00 and batch process starts at 21:30 Between these times periods refresh the dummy table every day using merge (to catch business transactions during the day)
Now during the batch process retrieve records from the main table using the rowids in the dummy table depending on the input status value
3)Create index on status Make sure hard coded status values are used in the database procedures Gather stats with the histograms And leave it to the Optimizer to choose the best possible path
The scale of the tests that generate the following scenario is not huge right now, only 50 users simulated (or you can think of them as independently running threads if you like). But here is the crunch, the queries generated (from generic transaction layer) are all running against a table that has 600 columns! We can't really control this right now, but this is causing masses amounts of IO (5GB per request) making requests queue for disk availability (which are setup RAID 0/1); its even noticable for as few as 3 threads.
I have rendered the SQL on one occasion to execute in 13 seconds for a single user but this appears short lived as when stats were freshly gathered it went up to the normal 90-120 seconds. I've added the original query to the file, however the findings here along with our DBA (who I trust implicitly) suggest that no amount of editing the query will improve the response times, increasing the PGA/SGA (currently 4/6GB respectively) will only delay the queuing for a bit and compression can work either. In short it looks as though we've hit hardware restrictions already for this particular scenario.
As I can't really explain how my rendered query no longer takes 13 seconds, it's niggling me that we might be missing a trick.So I was hoping for some guidance on possible ways of optimising these type of queries against such wide tables, in other words possibilities that we haven't considered...
Creating thread so we can share experience on using the "Code review options" that comes along with "Toad formatter".
Personally I have used it only for formatting code but not to enforce SQL Standards. any inputs on this and if it's advisable to use this as corporate standard.
we have table with 4 clob fields in it.to load text file of 4GB into the table it is taking around 2 hours. volumetric of that file is 40 Million. we are using direct=Y in sqlldr. but because of this clob fields we didn't got any performance improvement.
I have a master detail based transaction form, i want to create three check boxes on header block, based on selection sorting must happen on detail block which has three fields, for example there are three fields item_code,item_name,item_qty, if user selects first check box then sorting will be on item_code, if he presses second then sorting should be based on item_name, likewise if he presses check box three then sorting will be based on qty, if choses two or more fields then sorting will according to that combined order.
I came to know that, 11G Oracle R2 is not supported in Windows 8 64bit. So I want to install Oracle 10G Database on Windows 8. But not sure from where I can get the 10G DB software. provide the link to download the Oracle 10G Database .
I recently installed Oracle database 11g XE onto my home computer running Windows 32 bit, but I can't connect to the database. I also have Oracle 10g R2 installed on my computer, and I can still connect to it finely. When trying to make a connection in SQL DEVELOPER, I get this error
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I tried to tnsping the XE database and it returns successfully.
