ORA-04016

Hi,
I am getting an ORA-04016 (ORA-04016: sequence <name> no longer exists).
These are the statements:
1. CREATE SEQUENCE <seq> START WITH 1 INCREMENT BY 1 CACHE 1000 NOCYCLE
2. INSERT INTO <table1> (<columns>) SELECT <seq>.NEXTVAL, <columns> FROM <table2>
3. DROP SEQUENCE <seq>
I often call these statements without error, but suddenly the error occures in line 2. and after that time the error always comes up. I have to reconnect to the db to get rid of it.
There is only 1 session on that DB and the caller is single threaded. So concurrency is not an issue.
My question is: What does the error mean and how can I avoid it? I found nothing on the web about this.
Thanks,
Albrecht

Thanks for your time and thoughts.
To Raj: I'm inserting as many records as in table2 not just one. And I'm dropping the seq after using it because I have to recreate it when passing these lines of code next time.
To Jens: Do I have to be a paying member of something to view those bugs? (I am not - you guessed it). But regarding the title of the bug I think: no, I'm not dropping any users.
To all: Is there any programmer who hacked something like this into the oracle kernel: "IF USER=="albrecht" THEN THROW ORA-04016 SPORADICALLY"? I mean line 2 is a transaction and who if not the system can drop a sequence inside a transaction that uses it? I do not understand the real meaning of this error. What code do I have to provide to force the error running tha code first time?
TIA,
Albrecht

ORA-04016 - Sequence no longer exists

Hi,
In the below scenario
1. All the sequences are dropped
2. When a process requires a value from a sequence and the sequence is not available, it is created and then a sequence.nextval is executed.
This statement is returning a ORA-04016 - Sequence <XXX> no longer exists.
Based on the following Metalink 1300837.1, we tried putting a sleep(5) between the sequence creation and fetch. The problem still occurs intermittently.
DB Version is 11.2.0.2 on Exadata with 6 nodes.
Even after an extensive search on the web, I could not find anything.
Is there any workaround for this or is there some DB patch to be applied?
Thanks

Have you tried sleeping for longer?
Alternative approaches that spring to mind are:
1) Ensure that the statements that create the sequence and those that subsequently use it are executed on the same node when executed in close succession.
2) Trap the error and retry in your code.
I'd be inclined to favour suggestion 1 if possible in your environment.
Is your code in PL/SQL?

OS/Disk failure external to Oracle.
Oracle is victim; not the culprit.
After the disk throwing error is replaced, you will need to restore the DB from most recent backup.

It would be important to know what kind of backups do you have.
Do you have offline backup?
Do you have archive mode turned on?

advise:
1. 尝试cp 该文件到其他位置看是否能修复问题
2. 若步骤1 无效则在步骤1的基础上对该数据块做blockrecover,当然这需要该数据文件的全量备份和归档日志
3. 若没有备份考虑用 dbms_repair 包对该块标记为 corruption
建议你先查一下是否只有这样一个物理坏块，这个块具体属于什么segment，就EXP看应当是TABLE，
那么可以考虑用 10231 event + CTAS 重建该表，并DROP 原表后再 exp

Hi,
as i tried to understand your errors.i only came to know that the device on which the file is riside is probebley offline,or if this is your temporary file then it might be the case that your device has run out of space.or disk space for your temporary file is not necessarily allocated at the file creation.
remedy :- you can remove unnecessary space from the disk by cleaning unnecessary files.
thanks.

I am getting an error problem when i select certain Schemas from a list on an apex app. page, it only works for some schemas not all..
When i select one schema, it is supposed to display one row.. when i select [ALL] it is supposed to show them all.
It does work if i select '[ALL]' from the select list (p3_schema_name), just not for every single individual one.
the error code:
ORA-01422: exact fetch returns more than requested number of rows

Hello Ashleigh,
Based on your code, I'd start by running this piece of SQL via command-line (thru SQL Workshop, SQL*Plus, Toad, etc.), replacing &P3_SCHEMA_NAME. and &P3_DB_NAME. with values that are currently causing the routine to fail and see if it returns more than one row. I don't know your data, but DISTINCT and GROUP BY are typically used to return multiple (though grouped/summarized) rows. It appears to be the only statement that would cause the error your seeing (more than one row being returned into single variables).
select distinct DDH_DB_NM, max(DDH_SCHEMA_NR)keep(dense_rank last order by ddh_runstart_td) AS "PATCH" from &P3_SCHEMA_NAME..ddl_log@&P3_DB_NAME.db_link GROUP BY DDH_DB_NM;I'm actually surprised that the code runs at all. I didn't think 'execute immediate' would know what to do with substitutions indicated as "&something." (I've typically seen that when substituting in dynamic HTML/Javascript code but maybe I'm learning something new). But since you already have vServer2 and vSchema2, I'd be more apt to code it as:
vStmt2 := 'select distinct DDH_DB_NM, max(DDH_SCHEMA_NR)keep(dense_rank last order by ddh_runstart_td) AS "PATCH" from ' ||
vSchema2 || '.ddl_log@' || vServer2 || '.db_link GROUP BY DDH_DB_NM';Hope this helps,

Ora-00604 error and ora 01000 error while report generation.

hi all,
I am trying to generate the multiple reports of same template through a program.
While this job is running, i get the following error at the BIP console and the reports don't get generated.
[101711_044115578][][EXCEPTION] java.sql.SQLException: ORA-00604: error occurred
at recursive SQL level 1
ORA-01000: maximum open cursors exceeded
ORA-00604: error occurred at recursive SQL level 1
ORA-01000: maximum open cursors exceeded
ORA-01000: maximum open cursors exceeded
Kindly help.
Thanks.

Lots of resources with a simple search to see what this is about, for example:
http://www.orafaq.com/wiki/ORA-01000
ORA-01000:     maximum open cursors exceeded
Cause:     A host language program attempted to open too many cursors. The initialization parameter OPEN_CURSORS determines the maximum number of cursors per user.
Action:     Modify the program to use fewer cursors. If this error occurs often, shut down Oracle, increase the value of OPEN_CURSORS, and then restart Oracle.
open_cursors parameter

    FROM csbcrossworlds.subscriptions;We have 15 views in this schema, 3 of them fail this way but the other 12 display the columns just fine. So far I am unable to detect any commonality.
Any ideas?

Ok, I think I found the problem. The view in question (SUBSCRIPTIONS) is owned by 'PHILC' and it references a table named 'SUBSCRIPTIONS' owned by 'CSBCROSSWORLDS'. There are two other development schemas that also own tables named 'SUBSCRIPTIONS'.
I believe the 'Columns' tab is executing the query below. The subquery in this SQL tries to identify the primary key columns for the 'SUBSCRIPTIONS' view in my schema (PHILC):
SELECT
    c.column_name,
    DECODE(
        data_type,
            'CHAR',      data_type||'('||c.data_length||')',
            'VARCHAR',   data_type||'('||c.data_length||')',
            'VARCHAR2', data_type||'('||c.data_length||')',
            'NCHAR'   , data_type||'('||c.data_length||')',
            'NUMBER' , DECODE(c.data_precision,null,'NUMBER', data_type||'('||c.data_precision||','||c.data_SCALE||')'),
            'NVARCHAR', data_type||'('||c.data_length||')',
            'NVARCHAR2', data_type||'('||c.data_length||')',
            data_type) data_type,
    DECODE(nullable, 'Y', 'Yes', 'No') nullable,
    c.DATA_DEFAULT,
    column_id,
    com.comments,
    (SELECT 1 FROM all_constraints, all_cons_columns
      WHERE all_constraints.constraint_type = 'P' AND
            all_constraints.constraint_name = all_cons_columns.constraint_name AND
            all_constraints.owner = all_cons_columns.owner AND
            all_cons_columns.table_name = c.table_name AND
            c.column_name = all_cons_columns.column_name) Primary_Key,
    c_update.insertable,
    c_update.updatable,
    c_update.deletable
FROM
    sys.all_tab_Columns c, sys.all_col_comments com, sys.user_updatable_columns c_update

    c.owner = :OBJECT_OWNER AND
    c.table_name = :OBJECT_NAME AND
    c.table_name = com.table_name AND
    c.owner = com.owner AND
    c.column_name = com.column_name AND
    c_update.column_name = com.column_name AND
    c_update.table_name = com.table_name
;Extracting the subquery into this:
SELECT

    all_cons_columns.table_name = 'SUBSCRIPTIONS' and
    'ORDER_ID' = all_cons_columns.column_name;I got this output:
   owner          table_name      constraint_name
CUTOVER          SUBSCRIPTIONS    SUBSCRIPTIONS_PK
CROSSWORLDS      SUBSCRIPTIONS    SUBSCRIPTIONS_PK
CSBCROSSWORLDS   SUBSCRIPTIONS    SUBSCRIPTIONS_PKLooking at the DDL for the view, the row we really want is for owner 'CSBCROSSWORLDS'. Unfortunately, that means having to somehow parse the SQL text to extract the owner name...

Using database-link in view to get around ORA-01031 error

I have been granted select rights on a users table. I am therefore able to select from his table. If however I try create a view against his table I run into the ORA-01031 problem. I have worked around this problem by creating a database-link to myself and then adding that to the view creation and it works. What are the downsides of using the database-link in this way?

The only down side I have been able to identify is that a extra session is created and that the CPU has a little extra work due to the LOOP BACK that takes place. I need to ensure the network is not unnessesarly used and therefore will need to ensure that 127.0.0.1 (local host) is used in the database connection discription. e.g.
create database link my_db_link connect to scott identified by tiger using '(description=(address=(protocol=tcp)(host=127.0.0.1) (Port = 1521) ) (connect_data= (sid=ora10g)))';

Getting ora:00904 invalid indentifier error while running i query

Hi,
I have a remote database and local database both are oracle 10gR2.Now i have written the below mentioned query in my local database and is working fine,but in case remote database it is throughing error ora:00904 invalid indentifier.
I had export the dump from remote db and import it on my local db and i tried the same and it is working fine on local after that also.
As i believe that this error usually come for column name not exist or column name or it's length or for any special character in column name of the table.But as i said it is working fine on local db but not in remote db though i am using the same dump for local and remote.
Though when i am querying the table i can able to fetch data for the any record but when i am using the below mentioned query for the same i am getting the error.As i am doing this to fecth the data for child parent related relationship.
Can any one suggest is there anything related to configaration or something else.
Please do let me know if you do want some more information on the query what i am doing inside of it.
Rgds,
Anit
