Does cache buffer chain latch and buffer busy wait event are related to one any another.
Latch definition from Google says : Latches are simple, low-level serialization mechanisms to protect shared data structures in the system global area (SGA).
what does it mean my protect. Does this mean protects from aging as per LRU algorithm and getting removed from SGA or protect from other processes ,say from example from simultaneously DML operations. or both
Does buffer busy wait event occurs , because of the cache buffer chain latch ?
I have a form with 3 blocks in our oracle application. Block1 is a single record block. Block2 and block 3 are multi record blocks with no of records 5. Block1 and block2 are in same canvas1 of a window1. Block3 is in canvas2 of window2. There is a relation between block1 and block2. Another relation with block2 and block3 is also available.
Now my issues is while creating a record, first i entered the data in block1 (which is a single record block). Then i entered data in five rows of second block. Then i entered data in block3(multi record block) by pressing the button in block2 (each button for each row). But before saving the entire form, when i checked the data in block3 by pressing the button of first record of block2, screen shows empty.
Code in button of block2 is as follows
show_window(WIN2'); Go_block('BLOCK3');
Code in button of block3 is as follows
hide_window('WIN2'); go_block('BLOCK2');
If post; is included in block3 button. then problem we will be solved. But we don't want to use post; as it lock the table.
I have three database fields on my form , field_1 , field_2 and field_3 , user will enter the data in field_1 , and sometime he may not enter in field_2 ,
I want to bring the value of field_1 as it is into field_3 if he does not enter anything in field_2, if he enters the data in field_2 , then field_1 will get concatenated with field_2 and gets copied into field_3.Is there a way to do this automatically at form level using a trigger when-validate-item.In short this should be done after user presses the enter key on field_2.
create table ot_Sale_code_head ( sale_code varchar2(12),code1 varchar2(6),code2 varchar(6),code3 varchar2(12)); insert into ot_Sale_code_head ('A','01.01',NULL,NULL); --inserted record in form will be 'A','01.01',NULL,'01.01' insert into ot_Sale_code_head ('B','01.01','PS-P',NULL); --inserted record in form will be 'B','01.01','PS-P','01.01.PS-P'
I am developing an application for making the travel entries for my organization employees.
For that purpose I have 3 datablocks named: 1) Travel header 2) Employee Detail 3) Travel Detail which are interlinked through constraints.
I want to give 2 options ie. either single booking entry or Group booking entry.
The form is working properly for single booking entry. But when I want to make a group booking wherein many employees have to travel between common locations I have to fill all the travel details again for all employees. I want to avoid that since it wont give a feasibility for this application. I can copy the travel details I have entered for the 1st employee. I am uploading the form layout.
i have block display no of item 10.one of the field is time.now i want when i create new record the previews time should be auto copy into new item....
I have control block. In which user enters two values. Next is data block in which two items have property 'copy value from item' set to 'control block.item1' and 'control block.item2' resp. If thees items are made database items then in execute query will they be sent as parameters in addition to default where clause? if I check last query then query does not hv these parameters but the records returned are already filtered by control block items.
I have 2 blocks, namely addsubject3rd and chosensubjects. I'm copying the selected records(this comes with checkboxes) from the 1st block to the second block. But what happened is that it copied all the records that are on the addsubject3rd. How can I copy only selected records(checkboxes) from addsubject3rd block to chosensubjects blocks?
I have one drop down list box from which i want to do add or copy the values chosen from the list to another text box and then using this copied values ,i will pass them as parameters to run report.This list is getting populated using recordgroup and then what ever user chooses , it will be added to the another text box with space or delimiter.
I am using the HOST command within Oracle Forms 10g on Windows server to copy a pdf file from the application server to a network folder on another Windows server.
The command works fine if I logon to Windows app server and type it. But it doesn't work when it is launched within Oracle forms using HOST. The command looks as follow
net use \\FileServer\e-file /user:usergroup\username password & copy D:\RepTmp\myReport.pdf \\FileServer\e-file\test\myReport.pdf
Oracle forms doesn't give any error message at all but the pdf file never gets there. Even when I map the network folder as "R:" drive on the Windows app server, a simple copy command like this does not work with HOST:
copy D:\RepTmp\myReport.pdf r:\test\myReport.pdf
Oracle Forms server is running as "SYSTEM" on the Windows server. If HOST won't work, is there any other way to copy the file other than using fpt?
I need any good suggestion basically I have two different location
1- Factory 2- Head office
I have developed PRODUCTION module in factory and it is working fine and now I want to send data on daily basis to head office therefore I develop a form which will create backup in export format (.dmp) then user will send via email to head office.
Backup file should be save in pre-defined location then user will use a form which I developed for loading data into head office there are two different buttons in this form;
First is used to load data, actually first I load data in a temporary user which creates whenever user will press this button. Second is used to copy data in application user but first it checks if data exists then update otherwise insert.
I want to copy some rows in one column from Excel and Paste it in a Oracle Forms Progam. Normaly with the clipboard. But my Oracle Forms 6i Program copy alle the rows in one Field, separated with a | character. But I need it in several rows.

On working TI_Card_Info i have 2 columns Plastic_Card_Id and Plastic_Card_Type which i want to be paste on TI_limit_Indemnity data block as i enter in TI_Card_Info.
I am customizing a standard form to allow user to copy values. It works fine when I open the form, query a record and hit copy. But if I copy something to the clipboard from the records before I hit copy button, the form behaves differently and throw errors. Can I do something before the copy procedure work to eliminate this error?
I need to store a date that will always be x years before the current date. Is doing something like
select sysdate -x from dual
Going to result in any weird issues down the road? Also, because I haven't explicitly specified the date, when queried, will the value always be sysdate - x (What I want to happen) as opposed to dateRowWasCreated - x?
I have a varchar field in a table. When I store the following string, some undefined character is storing.
String to be stored: Test String String actually stored: Test ¿ string
Please note that here '' is not Hyphen. It is a special character that msword has. when you copy this and paste in a word document you find the difference.
I have listed the character set for CHAR and NCHAR from NLS_DATABASE_PARAMETERS
I'm writing a procedure that takes a table name as a parameter and I would like to print out the column name with the supporting row entry for each row. I know the logic I'd like to use, but how do you query the metadata to return the column names and store them.
In col4 , we have to update the values of col3 (column) ... it is very easy to update the values by executing the query for each column but my requirement is ... I want to execute the query once for a table ( example select col1_abc,col2_abc from table_abc ... this will return always a single value after adding other conditions in where clause) and why I want to do this? .. because there can be multiple (might be 30 variables values) from a single table.
I have converted the columns into rows by using listagg function now I have lets a dynamic query ( for the above example).
for i in 1.2 loop
l_query := ' select col1_abc, col2_abc from table_abc'; open c1 for l_query;
end loop;
my problem is : how to hold these values and update the above table?
i basically need to setup a schema for globalization. i need to handle brittish dollar signs, american dollar signs. etc.what is a global character setting i can use to handle almost everything?
my problem right now is that when i store a brittian dollar sign it converts it to a box. i need this preserved so i can select it and use it later.will the WE8ISO8859P1 character setting work? where is a good place to view all of the types of character settings? and what they are for. etc. and also how do you change such things? not for the session, but for a schema wide
