1. When querying the "alert_log" table I created from the alert log using the script below, 2 new files were created ALERT_LOG_30499.bad and ALERT_LOG_30499.log.
The ALERT_LOG_30499.log. contains this error message:
error processing column MSG in row 2910 for datafile /u02/damistst/admin/bdump/alert_damistst.log
ORA-12899: value too large for column MSG (actual: 82, maximum: 80)
the ALERT_LOG_30499.bad , so far, only contains datafile resize information. The datafiles have plenty of space and there is plenty of space on the San slice the datafiles reside.
2. then each time I recreate the table and increased the increased the varchar2 size, the "actual" size will also increase in the log file.
error processing column MSG in row 2910 for datafile /u02/damistst/admin/bdump/alert_damistst.log ORA-12899: value too large for column MSG (actual: 92, maximum: 90)
3. When I increased the varchar2 size to 120+ it gave me this error message:
[oracle@tds_dw bdump]$ cat ALERT_LOG_30715.log
LOG file opened at 03/09/11 14:46:20

**** QUESTION
I can still query the alert_log table in sqlplus, but those log and bad files are generated, is this an issue?

I am using trim function in my select query. But still I am getting white space in my output. because of this, I am getting the error "value too large for column... " when I load the data into a table through sqlloader.

I want to add column to table which has huge amount of data and fill with data from another table. What is the best way to do it? Is it faster to use CTAS instead of ALTER TABLE ADD COLUMN?
I have encountered some problems in SQL I want to create a table with a bunch of prepared data. For ease of use, I choose to generate a SQL file which contains all the sql clauses used to create the table and insert the data. So all the data can only be inserted to a table using sql clause.
My questions: 1) If data of a column is large (for example, 1 M text), how to insert it using SQL, is there a piecewise method. 2) And how can I insert BLOB data using SQL clause.
What I what is to enclose all the operations in a single SQL file, and when the table is needed, just execute this SQL file.

having looked at data in source system i cant see see character "Â" in the column 11 i think this is what causing issue !!why is oracle adding this character to this field ? how can i fix this ? without having to modify table in new system to allow more characters?
I keep getting the "ORA-01401:inserted value too large for column". No biggie - I've dealt with this multiple times before (but obviously not enough in this instance).
The data being entered is a SINGLE digit number - a number like 1, 2 or 3 - nothing fancy, just a plain straight everyday single digit number. The field in question is / was set as field type "Integer". Now, there is no set field size for integers! - not in Oracle anyway. Since it wasn't happy, I decided I'll try field types of 'Number' and also "Varchar2" set to 10 bytes. I have deleted the column from the table and re-created it as well.
Here's the even more puzzling bit: I can INSERT data into this field, BUT I can not UPDATE the field with the exact same data. The data is being inserted from a csv file. The same exact csv file used to insert works, but the same data in the same file will not update only that particular column.
If I delete the specific column data from the csv file, all goes through fine. If I hard code the update for the field (eg SET field2 = '1' or even SET field2 = ' ') it still doesn't work. So I know it is not the csv file that is causing problems. I deleted all data from the csv file except the field in question - still no luck.
So after eliminating: 1. The field type 2. The field length 3. The data being inserted 4. The external source of the data
I need to add a new column to a very large table, and update it with 'N'. (this is similar as specifying default 'N'). I'm using Oracle 9i. Which is the best method regarding to speed, to update this column on entire table? The table contains ~30 millions of records. I've read that parallel DML (here UPDATE) does not work on unpartitioned tables. My table is not partitioned. If i specify:
update /*+ full(p) parallel(p,10) */ my_table p set p.my_column = 'N';
This, i think will not speed up the operation on 9i. Our business does not accept to use CREATE TABLE AS SELECT, then renaming table and recreating all indexes and so on.
Can an undo tablespace be too large and actually hurt performance? I have seen a system with a dedicated 1 TB drive for undo tablespace (no guarantee) with an undo_retention of 7 days. Would this hurt performance? What about setting an undo_retention of 24 hours with no guarantee? The only mention I could find online said that it would not hurt performance but I wanted to double check. You would think that Oracle does not care if it deletes the undo at 15 minutes or if it deletes the undo at a later date such as 7 days later and the performance should stay the same.
I have oracle 11gr2 database on linux os. It's total sga size is 500mb only. Now, if uses wants read the 1gb of data from database, then there is no sufficient memory in buffer cache. so how it will works. the transaction will get successful or it will fail.And i have another doubt, does oracle can read the data from memory only or it can also read directly from disk.
I was asked in a telephone interview about committing a delete ( a few million rows)in an oracle log table which had a trillion rows in total. He said that delete took 2 days.
Then he asked me if then commit is performed(assuming a huge rollback segments are allocated) how long does it take for that commit .
$x being a range of non-consecutive values like so: 1,3,5-9,13,18,21 and so on...
I realize I can query using an array of operands and such, but these ranges will be in upwards of 100 or more items. I want to minimize the number of queries I have to do and the length of them. Is there any resource you can point me to that can optimize something like this?
is it possible to upload very large files in oracle's tables. For example 1-2 gigabyte video file or even more. In other words is it possible to use oracle as file server to upload very large files and store them?
I want to load 10 millions records from staging table to master table.One logic must be take during the load, the logic is rows already present in master table means, we need to update corresponding rows in master table otherwise rows insert in target table.
I have been using bulk collect and forall method to load data. it shows better performance compare then cursor row by row process. As per oracle doucmentation, we cannot use SELECT statements inside FORALL condition so we could not use logic inside the forall condition.
I need to dump the contents of a very large table into text files for archiving as we retire this old DB. The table has about 16 million rows, and a few of the columns are up to 4000 characters wide (varchar2(40000)). I've got 2 problems:
1) How can I select records that occur in a certain month of a year (there is a date column) and put the selected records into a file?
2) I don't have access to the server OS, so UTL_FILE is not possible. The output is also so large that I'm having trouble with the DBMS_OUTPUT.PUT_LINE.
I'm trying to get the first block of the IF working first, so the rest is just placeholders.

Since XML-files only contain character data, we could/should store it in a CLOB, rather than a BLOB.
But, One of my friend having a table where a column is defined as bloband came to know that XML data are being stored. I searched for some article with keyword 'How to insert large XML data in BLOB' But did not work.How to store the large xml content in a Blob and How to extract it?
Can i send a large file( over 1 million) as email attachment as .CSV file...?
I have a requirement to send a large file ".CSV" when the procedure / package is invoked as email attachment. The data in the CSV file is pulled from a table (as below).
(1) I tried below code to execute "send_email" which is uses utility UTL_SMTP. It is working fine with 100000 records and getting an email attachment with .csv (2) If more 100000 i am not getting any email / attachment.
I am looking forward to send a huge data like 1 million. >>>>>>>>>>>>>>>>>>>>> DECLARE l_clob CLOB; l_attach_text VARCHAR2 (32767); l_attach_text_h VARCHAR2 (32767); Cursor c1 is SELECT LOCATION,PARTY_NAME,ADDRESS1,CITY,STATE_PROV,COUNTRY,POSTAL_CODE FROM emp_table; [code].......
I'm looking for a way to insert strings larger than 40.000 characters in a CLOB-field without geting the "ORA-01461: can bind a LONG value only for insert into a LONG column".
Something like this:
insert into MyClobTable(ID,Data) values ('101','A string containing more than 40000 characters...')
The problem is that a Java-application concatinates the string from a MSSQL-DB so I don't store the string in my oracle-DB. As far as I'm aware this means I can't chop my string in pieces and use declare to put the pieces in variables, right?
Below is an example I found but I don't think I can apply it on my case, correct?
SQL> CREATE TABLE myClob 2 (id NUMBER PRIMARY KEY, 3 clob_data CLOB);
I have a query that returns 11 Million rows but not all of them can be displayed in SQLDeveloper or DBVisualizer because of limited memory or other type of issues. I need to copy the entire result set to excel for further calculations.
Is there any way that i can select N number of rows out of my actual result set.
For example: a) A result set contains 10 Million rows in total. b) I want to display first 5 Million rows by executing a query c) Then I want to display the remaining 5 Million rows by executing the query again with any parameter changes.
So all I want is to extract the rows of my actual result set in two or more executions, depending on the number of rows.
I'm currently new to Oracle 10g SQL and I need to query a large library file.I need to find the different first keywords associated with references written by authors who have more than 10 references in the readings table.
It always used to be that Automatic Memory Management and Linux huge pages were incompatible: you had to use one or the other. But 11.2.0.2 has new parameter, USE_LARGE_PAGES. This isn't documented apart from a few articles on metalink, but Googling it suggests that if it is on TRUE (the default) or ONLY then I can use AMM with huge pages.
