Weblogic LLR tables RECORDSTR column size issues
Hi ,
We have configured the LLR (Last logging resource to emulate 2 Phase commit XA ) non XA datasouce in our weblogic 10.3.5 domain and I see that weblogic internally creates WL_LLR_<servername> tables in the schema confgured with that LLR datasouce per managed server.
But during some transactions commit we are facing an error stating that RECORDSTR column size (which is default 1000 Bytes) is too small for the COMMIT RECORD. It works fine when we increased the RECORDSTR column to 2000 bytes . But the issue is what is the criteria to increase the column size , our application have a large global transactions and will 2000 bytes will be enough to hold that.
So my question is what actually gets stored within the LLR tables for a transaction , transaction logs or COMMIT record ? , what does COMMIT RECORD actually mean?
Is there a way to specify the table and column length of LLR Tables during creation of LLR data sources itself.
Maybe this can shed some light on things: http://docs.oracle.com/cd/E21764_01/web.1111/e13737/transactions.htm#i1145819

RoboHelp 10 - Table Preferred Column Width Issue
I converted a RoboHelp 9 project to RoboHelp 10 and noticed that Column 1 in all tables has a preferred width setting of 93% and it is not allowing me to remove this setting. When I uncheck the Preferred width checkbox and click OK, then go back to the Table Properties>Column tab, the Preferred width checkbox is checked again with a width setting of 93%. The column width is not specified in the HTML, it is set to fit to the contents (<col />). The odd thing is that Column 1 only displays this way in Design view. When previewing and publishing the topic, it displays correctly (fits to contents). This however makes editing content in tables extremely difficult in Design view. Any assistance is appreciated.
If it doesn't have a width setting of 93%, where are you finding it is set to 93%?
There was a bug in Rh10 with table widths and I cannot recall the exact details without some testing. I think it was along the lines that in design view there would be problems unless the columns had a width and so did the table.
I do know that once I set up tables in a specific way, they were also fine in design view. Post back if stuck and I will look but it may not be for a few days.

What table column size is needed to accomodate Unicode characters
Hi guys,
I have encounter something which i dont understand and i hope gurus here will shed some light on me.
I am running a non-unicode database and i decided to port the data over to a unicode database.
So
1) i export the schema out --> data.dmp
2) then i create the unicode database + create a user
3) then i import the schema into the database
during the imp i can see that character conversion will take place.
During importing of data into the unicode database
I encounter some error
saying column size is too small
so i went to check the row that has the column value that is too large to fit in the table.
I realise it has some [][][][] data.. so i went to the live non-unicode database and find the row. Indeed it has some [][][][] rubbish data which i feel that someone has inserted other language then english into the database.
But regardless,
I went to modify the column size to a larger size, now the row can be accommodated. However the data is still [][][].
q1) why so ? since now my database is unicode, during the import, this column data [][][] should be converted to unicode already but i still have problem seeing what language it is.
q2) why at the non-unicode database, the [][][] data can fit into the table column size, but on unicode database, the same table column size need to be increase ?
q3) while doing more research on unicode, it was said that unicode character takes up 2 byte per character. Alot of my table data are exactly the same size of the table column size.
E.g Name VARCHAR2(5);
value - 'Peter'
Now if converting to unicode, characters will take 2byte instead of 1, isnt 'PETER' going to take up 10byte ( 2 byte per character ),
why is it that i can still accomodate the data into the table column ?
q4) now with unicode database up, i will be supporting different language characters around the world. How big should i set my column size to ? the longest a name can get ? or ?
Thanks guys!/// does oracle automatically "look" at the each and individual characters in a word and determine how much byte it should take.
Characters usually originate from a keyboard, which has an associated keyboard layout and an associated character set encoding (a.k.a code page, a.k.a. encoding). This means, the keyboard driver knows that when a key with a letter "á" on it is pressed on a French keyboard, and the associated character set encoding is MS Code Page 1252 (Oracle name WE8MSWIN1252), then one byte with the value 225 is generated. If the associated character set encoding is UTF-16LE (standard internal Windows encoding), two bytes 225 and 0 are generated. When the generated bytes travel through APIs, they may undergo character set conversions from one encoding to another encoding. The conversion algorithms use translation tables to find out how to translate given byte sequence from one encoding to another encoding. In case of translation from WE8MSWIN1252 to AL32UTF8, Oracle will know that the byte sequence resulting from conversion of the code 225 should be 195 followed by 161. For a Chinese characters, for example when converting it from ZHS16GBK, Oracle knows the resulting sequence as well, and this sequence is usually 3 bytes.
This is how AL32UTF8 data gets into a database. Now, when Oracle processes a multibyte string, and needs to look at individual characters, for example to count them with LENGTH, or take a substring with SUBSTR, it uses information it has about the structure of the character set. Multibyte character sets are of two type: fixed-width and variable-width. Currently, Oracle supports only one fixed-width multibyte character set in the database: AL16UTF16, which is Oracle's name for Unicode UTF-16BE encoding. It supports this character set for NCHAR/NVARCHAR2/NCLOB data types only. This character set uses two bytes per each character code. To find the next code, 2 is simply added to the string pointer.
All other Oracle multibyte character sets are variable-width character sets, including AL32UTF8. In most cases, the length of each character code can be determined by looking at its first byte. In AL32UTF8, the number of 1-bits in the most significant positions in the first byte before the first 0-bit tells how many bytes a character has. 0 such bits means 1 byte (such codes are identical to 7-bit ASCII), 2 such bits mean two bytes, 3 bits mean 3 bytes, 4 bits mean four bytes. 1 bit (e.g. the bit sequence 10) starts each second, third or fourth byte of a code.
In other ASCII-based multibyte character sets, the number of bytes is usually determined by the value range of the first byte. Bytes below 128 means a one-byte code, bytes above 128 begin a two- or three-byte sequence, depending on the range.
There are also EBCDIC-based (mainframe) multibyte character sets, a.k.a shift-sensitive character sets, where a sequence of two-byte codes is introduced by inserting the SO character (code 14=0x0e) and ended by inserting the SI character (code 15=0x0f). There are also character sets, like ISO-2022-JP, which use more complicated byte sequences to define the length and meaning of byte sequences but Oracle supports them only in limited number of places.
/// e.g i have a word with 4 character. the 3rd character will be a chinese character..the rest are ascii character
/// will oracle use 4 byte per character regardless its ascii(english) or chinese
No.
/// or it will use 1 byte per english character then 3 byte for the chinese character ? e.g.total - 6 bytes taken
It will use 6 bytes.
Thnx,

Oracle APEX 4.0 - Interactive Report - Table Column Filter Issue
Environment: Oracle APEX 4.0 - Interactive Report - Table Column header Filter Issue
We have developed an interactive report using Oracle APEX 4.0, which contains a record count of around 3,000 Rows. All the rows values are unique in nature. When we try to filter the same with the help of column header filter option available in the interactive report,We get only 1000 records.
Could some one help us, why this behaviour under APEX Table Column Header Filter as if it does not display beyond 1000 distinct values.
Is there a way or workaround on how to get all the records in the column header filter?
Thanks in advance.

Data type column size does not match size of values returned
I've tried searching but couldn't find what I was looking for, sorry if this has been answered or is a duplicate.
I am using the (Java) method below to get the column definitions of a table. I am doing this through an ODBC connection (using Oracle ODBC driver) and I have NO CHOICE in the matter.
The problem I am having is that one particular column has a column size is smaller than the size of the data it purportedly holds (ie attendance_code = varchar size 3 but data value is "Absent". I suspect the data is actually a look up to situation, where my attendance_code column has a value of 'ABS' and Oracle goes and fetchs the "Absent" value.
My issue is that the meta data returned from ODBC is the actual column definition (ie varchar(3) and not varchar2(10) for example).
The resultset metadata has a size of 3 for the column in question, and querying the schema also yields 3 for that column.
How do I resolve this? I do not have access to all_columns table etc. I have to do it using ODBC metadata only.
I've tried recreating the situation using the Oracle XE DB, but as I am not familiar with Oracle, I do not know how to recreate this scenario (which would then lead me to test other options with ODBC).
TIA.
The select I am using is SELECT * FROM <tableName>.
public ArrayList<SchemaColumn> getColumnsForTable(String catalog,
String schema,
String tableName) {
ArrayList<SchemaColumn> columns = new ArrayList<SchemaColumn>();
ResultSet rs = null;
try {
DatabaseMetaData metaData = connection.getMetaData();
rs = metaData.getColumns(catalog, schema, tableName, "%");
SchemaColumn column;
while (rs.next()) {
column = new SchemaColumn();
column.setName(rs.getString("COLUMN_NAME"));
column.setDataType(rs.getInt("DATA_TYPE"));
column.setTypeName(rs.getString("TYPE_NAME"));
column.setColumnSize(rs.getInt("COLUMN_SIZE")); <-------- this is the value that is coming back smaller than the data it actually returns
column.setDecimalDigits(rs.getInt("DECIMAL_DIGITS"));
column.setNumPrecisionRadix(rs.getInt("NUM_PREC_RADIX"));
column.setNullable(rs.getInt("NULLABLE"));
column.setRemarks(rs.getString("REMARKS"));
column.setDefaultValue(rs.getString("COLUMN_DEF"));
column.setSqlDataType(rs.getInt("SQL_DATA_TYPE"));
column.setSqlDateTimeSub(rs.getInt("SQL_DATETIME_SUB"));
column.setCharOctetLength(rs.getInt("CHAR_OCTET_LENGTH"));
column.setOrdinalPosition(rs.getInt("ORDINAL_POSITION"));
columns.add(column);
} catch (Exception e) {
Log.getLogger().error("Could not capture table schema");
closeResultSet(rs);
return columns;
}I can't say I've ever seen a case where a column held more data than it was declared as, and would have to file that under "see it to believe it" category.
Even if that somehow were the case, I'd expect the ODBC driver to return what the column is defined as anyway, not the data. The data changes with every row, but I'd expect the table metadata to be consistent, and refer to the table definition.
For grins though, can you provide system.out.println output of the metadata, and also a "describe xxxx" from sqlplus if you can, where xxx is the table name?
ie,
while (rs.next()) {
System.out.println("column name is " + rs.getString("COLUMN_NAME"));
System.out.println("data type is " + rs.getInt("DATA_TYPE"));
..etc..

Hi All,
I've got a doubt regarding alter the column size.
There's a table column which is currently 255 and I want to increase it to max i.e. 4000 Char
It is used in many places by various objects - Procs/Packages/Triggers/Views...
Is it advisable to use Varchar2(4000Char) or using LONG or CLOBS??
If I use LONG/CLOB now, will it affect the existing objects since they believe the column to be VARCHAR2...?
Help highly appreciated.

Hi All,

There's a table column which is currently 255 and I want to increase it to max i.e. 4000 CharBe aware, the Maximum is 4000 bytes not char. If your database is using a multi byte character set, the maximum could actually be as small as 1000 characters (if you have 4 bytes per character).
It is used in many places by various objects - Procs/Packages/Triggers/Views...
Is it advisable to use Varchar2(4000Char) or using LONG or CLOBS??Never use LONG. the LONG datatype was deprecated over a decade ago. If you're needing to store large amounts of text, use CLOB.
If I use LONG/CLOB now, will it affect the existing objects since they believe the column to be VARCHAR2...?It's one of those "it depends" answers, because it depends what the code is doing with it. It's not so much a case of the code/objects believing it to be varchar2, but whether that code or objects can do implicit conversions without issue. If it's just a case of something inserting into it, believing it's a varchar2, then it would work ok e.g.
SQL> create table mytable (x clob);
Table created.
SQL> insert into mytable (x) values ('This is my varchar string');
1 row created.The problem would obviously be if there is code that is reading the data into a varchar2 variable or datatype and the data exceeds the 4000 byte limit, in which case you will get issues.
The best way to look at is is... Yes, it will effect existing code/objects, and you need to carry out an impact analysis to see where and how it's used. -
Good day,
I searched through the forum and cant find anything.
I have around 300 published reports on SSRS and we are busy migrating to a new system.
They have already setup their tables on the new system and I need to provide them with a list of table names and column names that are being used currently to generate the 300 reports on SSRS.
We use various tables and databases to generate these reports, and will take me forever to go through each query to get this info.
Is it at all possible to write a query in SQL 2008 that will give me all the table names and columns being used?
Your assistance is greatly appreciated.
I thank you.
Andre.There's no straightforward method for that I guess. There are couple of things you can use to get these details
1. query the ReportServer.dbo.Catalog table
for getting details
you may use script below for that
http://gallery.technet.microsoft.com/scriptcenter/42440a6b-c5b1-4acc-9632-d608d1c40a5c
2. Another method is to run the reports and run sql profiler trace on background to retrieve queries used.
But in some of these cases the report might be using a procedure and you will get only procedure. Then its upto you to get the other details from procedure like tables used, columns etc

Report Generation excel column size
Dear,
In the project, I save the data in Excel with Report Generation. I would like change just the column size of my Excel report. There is an explanation in the labview help but I have always an error when I run the VI.

Create materialized view with specific column sizes
Hi all,
I'm trying to create a materialized view with a specific a column size. Something like
create materialized view test_mv
refresh force on demand
as
select id,
cast(my_compound_field as nvarchar2(50))
from ( select id,
field1 || field2 my_compound_field
from my_table);But Oracle seems to ignore the cast and takes the maximum size it finds for field1 || field2 in the select query. The resulting table has a column nvarchar2(44) instead of nvarchar2(50).
This can give a problem when the view is refreshed... there could be new data that exceeds the current size, i.e. where length(field1 || field2) > 44.
How can I override the column size of a field in a materialized view?
Edit: Some additional info to clarify my case:
field1 and field2 are defined as nvarchar2(25). field1 || field2 can theoretically have a length of 50, but there is currently no data in my table that results in that length, the max is 44. I am afraid that there will be data in the future that exceeds 44, resulting in an error when the MV is refreshed!

Gather_table_stats with a method opt of "for all indexed columns size 0"
I have 9 databases I support that contain the same structure, and very similar data concentrations. We are seeing inconsistent performance in the different databases due to bind variable peeking.. I have tracked it down to the Min and Max values that are gathered during the analyze. I analyze from one cluster, and export/import those statistics into the other clusters.. I then go about locking down the stats gathered. Some of the statistics are on tables that contain transient data (the older data is purged, and new data gets a new PK sequence number).
Since I am gathering statistics with a 'FOR ALL INDEXED COLUMNS SIZE 1', a min and max value are grabbed. This value is only appropriate for a short period of time, and only for a specific database. I do want oracle to know the density to help calculate, but I don't want cardinality based on whether the current bind values fall in this range..
Example
COLUMN PK
When I analyze the min is 1 and max is 5. I then let the database run, and the new min is 100 and max is 105.. same number of rows, but different min/max. At first a select * from table where pk>=1 and pk <=5 would return a cardinality of 5.. Later, a seelct * from tables where pk>=100 and pk<=105 would return a cardinaility 1.
Any ideas how to avoid this other than trying set min and max to something myself (like min =1 max = 99999999). ??MarkDPowell wrote:
The Oracle documentation on bind variable peeking said it did not peek without histograms and I cannot remember ever seeing on 9.2 where the trace showed otherwise. Mark,
see this simple test case run on 9.2.0.8. No histograms, but bind variable peeking, as you can see that the EXPLAIN PLAN output generated by AUTOTRACE differs from the estimated cardinality of the actual plan used at runtime.
Which documentation do you refer to?
