One of our developers team member had created a Anonymous block program to do something in the Database, and he forgotten and terminated the session without confirming the program's status, whether it was fully ran or not.
Is there any way to check out the status of this, which happened yesterday?
I am trying to run the following script but some how i am getting message: anonymous block completed. where i am doing wrong and also how can i display the values with their column names.

I made this script but I still don't quite understand if the syntax is correct. I just wanted to create a function and call it in an anonymous block. I then wanted it to use a variable as a parameter in an iteration and output the variable every iteration. It's done basically but I know it's not 100% right. The fibonacci function looks like its going to loop an infinite number of times if the parameter is greater than 2.
CREATE OR REPLACE PACKAGE myPACKAGE AS

Is it possible to create autonomous transaction in anonymous block.
find the below code, when I am trying to execute I am getting error
CREATE TABLE EMP (EMPNO NUMBER(4) NOT NULL,
ENAME VARCHAR2(10),
JOB VARCHAR2(9),
MGR NUMBER(4),
HIREDATE DATE,
SAL NUMBER(7, 2),

The following query gives me 28,800 as sum(sal)
SELECT SUM(salary)
FROM employees
WHERE department_id =60
O/P is : 28800But when i use the above query in anonymous block it gives me 684400
DECLARE
v_sum_sal NUMBER;
[code]....
The above output statements gives me 684400 as output.. But the expected is 28800
can we place insert statement in loop inside anonymous block?
CREATE TABLE DEP(DEPTID NUMBER(5) NOT NULL PRIMARY KEY,DNAME VARCHAR2(10),LOCID VARCHAR2(10));
DECLARE
I NUMBER(5);
BEGIN
I := 0;

INSERT INTO DEP VALUES(&DEPTID,'&DNAME',&LOCID);
I := I+1;
EXIT WHEN I = 5;
END LOOP;

My application is opening a lot of sessions in my DB server. I applied resource_limit=true and idle_time=15 min. ans assign this profile to all application user.
Now I am seeing a lot of sessions having status sniped in v$session.
I want to clean up these sniped sessions and what they mean.
what does 'SNIPED' status in v$session mean? It is killed/ clear from instance automatically or need to kill manually for releasing the resource.
View 3 Replies View RelatedI need to display the parameter and status of DB for listener and Read Only.
I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.
how can i monitor the instance status and log switch summary.
View 8 Replies View RelatedI have a requirement to get decrypted value of national_identifier from database and display in Social Security number, when user queries for employee in employee form of HRMS. Also, National_identifier should be in encrypted format in database table always.
To meet above requirement, I am using custom.pll. In WHEN-NEW-BLOCK-INSTANCE I am getting decrypted value of national_identifer from database and assigning it to :person.national_identifier(database block) by using COPY function, so far it is working as expected.
When user query for employee, he/she able to decrypted value. but if user closes the form it is asking 'Do you want to save changes you made' as there is a change in :person.national_identifier.
Do we have any property to reset record/block status to something like unchanged, so we will not get 'Do you want to save changes you made message'.
I have a scenario wherein i want to enable / disable a block based upon value of one of its column value. i.e., if value of approval status in
(IN ( 'INCOMPLETE' , 'RETURNED' , 'REJECTED' ) THEN
SET_BLOCK_PROPERTY('RFN_HEADERS_ALL', UPDATE_ALLOWED, PROPERTY_TRUE);
SET_BLOCK_PROPERTY('RFN_LINES_ALL', UPDATE_ALLOWED, PROPERTY_TRUE);
SET_BLOCK_PROPERTY('RFN_HEADERS_ALL', DELETE_ALLOWED, PROPERTY_TRUE);
SET_BLOCK_PROPERTY('RFN_LINES_ALL', DELETE_ALLOWED, PROPERTY_TRUE);
else.....
but the code is not working in pre-query, pre-select or post-query
Is it possible to get the status of form or block every time? I mean if user presses Enter query key, it should display some status and if user presses execute query key then it should reflect some status. If user update any then it should reflect.

2) How to calculate the no of data blocks were used to return a single output.
I am using oracle 10g with sga_max_size =4GB and db block size 16k. Now i am creating a tablespace with block size 32 kb , whats value i select for the parameter db_32k_cache_size.
Is there any standard way to calculate the value of this parameter.

in the ⑧ step,why block#685,block#686,block#687,block#688 in the buffer cache after i query data from scott.T2012?
QUESTIONS TWO:
in the ⑨ step,what's the block number of the empty block?just like DBMS_ROWID.ROWID_BLOCK_NUMBER(ROWID).
Is there any way I can calculate percentage of space used in a block.Eg if a table size is 100 blocks,How Can I check the percentage of used space in block.
View 6 Replies View Relatedfor some reason,i want to know which data block contains free space,or which table/index contains free space.

2) How it occurs.
3) Will RMAN works on both the types of corruption or only Physical (My senior told it works on both).
We are creating non standard blocking size for 16k and so accordingly have to set the parameter db_16k_cache_size.
if have any thumb rule for setting the value for this parameter.
I am in charge of several instances located on a Linux server CentOS, virtualized on a ESX 3.5 environment.
From time to time (every 4 to 5 days), I have some errors in the alert.log. Last occurence was last night :
Corrupt block relative dba: 0x01004e12 (file 4, block 19986)
Fractured block found during buffer read
Data in bad block:
type: 6 format: 2 rdba: 0x01004e12
last change scn: 0x0000.131aaa5b seq: 0x2 flg: 0x04
[Code] ........
We are doing user manual backup (with BEGIN/END BACKUP) every night at 8PM, ending at 9PM approx. Then, fractured blocks never occur during backups. At 1AM, the maintenance window is opening, thus explaining the GATHER_STATS_JOB job.
When I check corruption on early morning, I am always unable to reproduce the problem. DBV is OK without issues. We never had a problem with the data itself, whatever it is a table or an index in the reported failed block.
I would like to know what could cause these logical corruption, and how to stop them ?
I have a database where view v$database_block_corruption shows a corrupted block

My understanding of DB_FILE_MULTIBLOCK_READ_COUNT parameter is that it affects only Full Table Scans and Fast Full Index Scans - all other disk retrieval is single block.If so, then maybe I'm reading this trace incorrectly:
select /*+ first_rows */ pk
from test_join_tgt
where pk >= 0
and rownum > 1
call count cpu elapsed disk query current rows

What the heck is going on with the Multi-block reads in the Range Scan?
Error is occurred during the transaction...i.e.
