Resolving errors ORA-01652 and ORA-04031

Hi,
My database is 8.1.7
i am frequenty getting this error.
suggestion required.

For ORA-01652, check free space in your datafiles.
For ORA-04031, upgrade to Oracle 8.1.7.4.1 or higher.

Error ORA-04031 while executing a stored procedure from Pro C++ code

I am getting the error ORA-04031(Unable to allocate 4096 bytes of shared memory("Shared Pool",.....)) while trying to execute a stored procedure from my pro*C application. This happens only after a few hours since the application has been running. I am closing the cursor after every database call.
Does anyone know why it is happening and any possible solutions?
TIA
Srithaj.

One thing that can be done is to flush the shared pool before starting the application.
alter system flush shared pool;
Another is to increase the shared pool size by setting the parameter shared_pool_size in init_sid.ora file.
null

I have an error ora-04031 on XE 11g

hello,
I have an error ora-04031 on XE 11g
When I restart DB, this error is fixed.
Can I set any parameter(SHARED_POOL_SIZE) to fixed this error?
OS:win 2003 server
ora-00604: error occurred at recursive SQL level 1
ora-04031: unable to allocate 4064 bytes of shared memory ("shared pool","select t.rowcnt, t.blkcnt, t...","sga heap(1,0)","kglsim heap")

Hello,
Can I set any parameter(SHARED_POOL_SIZE) to fixed this error?There actually is a parameter, but in 11g XE it's not effective by default because Automatic Memory Management (AMM) is activated. AMM tries to tune the different memory parameters to achieve best performance for all activities in the database.
You can disable automatic memory management, but I'd not recommend to do that unless you really know what you do.
In your case, I'd start to investigate if a perticular query is causing that issue and you might be able to tune it, so it needs less memory. A second step would be to check whether your instance is already using the 1 GB you can have in XE. To find out, run the following query
select * from v$parameter where name in ('memory_target', 'sga_target','sga_max_size','pga_aggregate_target');The parameters for AMM would be memory_target and memory_max_target where memory_target is the effecitve maximum amount of memory used by XE. If it's not enabled (set to 0), the other three might be effecitve.
To increase the value for memory_target you can run
alter system set memory_target=<size>M;where +<size>M+ would be the amount of memory in megabytes. As mentioned before, you can assign a maximum of 1 GB and not more than you've defined in the memory_max_target parameter. To increase that value, you need to run
alter system set memory_max_target=<size>M scope=spfile;and restart your database before you can alter memory_target to a higher value.
BTW: For further investigation you don't need to restart the database to reset the shared pool: You can do this by issuing the following command
alter system flush shared_pool;If this all doesn't help, I'd recommend to dig in deeper into memory management of the Oracle Database. But let's start with first steps first.

ORACLE error ORA-04031: unable to allocate 16 bytes of memory

Error

Hello,
you could try to override the automatic memory management and setup your SGA to be larger by setting SGA_TARGET. If that doesn't help yet, you could even try to configure the memory size for the components in SGA manually, but I guess this won't be necessary.
After your import is done, I'd recommend to use automatic memory management again.
See the XE 2 Day DBA for details, especially the section on [url http://download.oracle.com/docs/cd/E17781_01/server.112/e18804/memory.htm#ADMQS174]Managing Memory. It's not a complete guide, but a rough introduction, but it'll probably help you understand the memory concepts in the database.
Keep in mind that you may only assign 1 GB of memory in total when you setup your memory manually.

How to resolve error ORA-29491: invalid table for chunking?

Hello,
I'm trying to implement DBMS_PARALLEL_EXECUTE to speed up a huge update I need to do. I'm stuck on a problem with the table I'm using to test my procedure. Here's a simple test that produces the same error. As best I can tell, the table I'm declaring here is missing some kind of requirement that lets DBMS_PARALLEL_EXECUTE make use of it, but the docs and searching for the error code haven't turned up any useful discussions. Please help.
drop table owner.why_cant_i_hold;
create table owner.why_cant_i_hold (
things VARCHAR2 (64),
amount INT,
CONSTRAINT why_cant_i_pk PRIMARY KEY (things)
insert into why_cant_i_hold values ('limes', 8);
insert into why_cant_i_hold values ('lemons', 8);
insert into why_cant_i_hold values ('watermelons', 5);
insert into why_cant_i_hold values ('cats', 4);
insert into why_cant_i_hold values ('teacups',10);
insert into why_cant_i_hold values ('mugs', 5);
insert into why_cant_i_hold values ('eggs', 15);
insert into why_cant_i_hold values ('jobs', 3);
commit;
-- got tasks?
COLUMN task_name FORMAT A10
SELECT task_name,
status
FROM user_parallel_execute_tasks;
--exec DBMS_PARALLEL_EXECUTE.CREATE_TASK('holding');
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'ODDEV03', 'why_cant_i_hold', true, 3);
It seems like a really simple case here. The output is all successful until
"Error starting at line 25 in command:
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'owner', 'why_cant_i_hold', true, 3);
Error report:
ORA-29491: invalid table for chunking
ORA-06512: at "SYS.DBMS_PARALLEL_EXECUTE", line 27
ORA-06512: at "SYS.DBMS_PARALLEL_EXECUTE", line 121
ORA-06512: at line 1"

Oh. This was an easy one, table names are never really lower-case. Changing the value in my chunking call fixed the simple test:
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'ODDEV03', 'WHY_CANT_I_HOLD', true, 3);
It doesn't help with why my more complicated test case isn't working, but I have details to check before I ask again.
EDIT: lesson learned... 'invalid table' doesn't mean the database can find the table you are talking about at all. I hope that's a help.

There could be a few reasons causing the problem. From literal message it would look like your shared pool size is small and you need to increase. But the root cause of the problem is a little more complicated than that. I suggest you read metalink doc

Diagnosing ORA-04031 on Oracle9iR2

Hi
We're running an Oracle9iR2 (9.2.0.6) database on Red Hat Enterprise Linux 4.0 (IA32). The database is used for development and testing. It's been running ok until recently users started getting the following error when trying to connect to the database:
ORA-04031: unable to allocate 17168 bytes of shared memory ("shared pool","unknown object","sga heap(1,0)","session param values")
What's changed during the last weeks is that we've installed Oracle10gR2 and the Oracle Calendar server on the machine, and added a about 10-20 new user accounts.
The server was originally running in dedicated server mode until i noticed there were 115 Oracle processes running on the server at one moment. The database typically has large number of connections which are idle most of the time. I changed it to shared server mode in order to avoid the overhead of having lots of server processes which are doing nothing most of the time.
I also increased the shared_pool_size and large_pool_size on the server but i'm still seeing ORA-04031 errors in trace files. How do i determine whether the cause is shared or large pool? How do i determine the right sizes for these pools? The traces include heap dumps for large pool.
The SQL query appearing in the trace files cursor name section is just one type of SQL query in most of the cases. How can i debug shared memory usage for a particular SQL query so that i can try and modify it to a more memory economic direction?

Hi,
If you have access to metalink, I advise you to read 146599.1 Diagnosing and Resolving Error ORA-04031.
The SQL query appearing in the trace files cursor name section is just one type of SQL
query in most of the cases. How can i debug shared memory usage for a particular SQL
query so that i can try and modify it to a more memory economic direction?The following SQL can show you statements with literal values or candidates to include bind variables:
SELECT substr(sql_text,1,40) "SQL",
count(*) ,
sum(executions) "TotExecs"
FROM v$sqlarea
WHERE executions < 5
GROUP BY substr(sql_text,1,40)
HAVING count(*) > 30
ORDER BY 2;Note: The number "30" in the having section of the statement can be adjusted as needed to get more detailed information.
There is a fixed table called x$ksmlru that tracks allocations in the shared pool that cause other objects in the shared pool to be aged out. This fixed table can be used to identify what is causing the large allocation.
SELECT * FROM X$KSMLRU WHERE ksmlrsiz > 0;Note : This view can only be queried by connected as the SYS.
How have you RAM ?
Since your last install, perhaps your RAM is not sufficient any more ?
Check your memory occupation.
Nicolas.
How do i determine whether the cause is shared or large pool? If there is no free memory into large pool left when a request is made then an ORA-4031 will be signalled similar to this : ORA-04031: unable to allocate XXXX bytes of shared memory
("large pool","unknown object","session heap","frame")

Hi Santosh,
This is what i faced last two days back! Now i am monitoring the Issue! If you got any solutions please let me know how to avoid this!
ORA-04031 error can be due to either an inadequeate sizing of the SHARED POOL size or due to heavy
fragmentation leading the database to not finding large enough chuncks of memory.
You can monitor this with the two events...
alter system set events '4031 trace name errorstack level 3';
alter system set events '4031 trace name heapdump level 3';
Fragmentataion is one of the causes of ora 4031
Please refer these.

SAP BW with ORA-04031 Errors

Hello All,
Context:
We have a financial closing system working in the BW 3.5 and Oracle 9.2.0.7.0.
We are working with more than 100 millions records in 3 days.
In general, the system uses the standard data marts and BPS processes (copy, distribution, etc).
Error:
We had a lot of ORA-04031 errors for all execution (ABAP Programs, Data Loads, BPS Executions), it stopped the environment.
We did the "stop/start" the server to solved the problem.
The basis team increase the parameter "shared_pool_size" = 3000M - We saw the SAP Note (690241) and which is more than enough.
We have fear about it, we think it is posible to occurs again.
This is a big impact for the business.
Have you got this error in the past?
Could you please help us.
Thanks a lot.

Hi Chandran,
We saw this note.
The basis team have been changed the KGHDSIDXCOUNT parameter ( 4 to 1).
I am not founding more causes for this problem in the note.
Is it posible to have problems if the DB_CACHE_SIZE parameter is very large? example 18000M?
The basis team reduces the value for 1700M, in the last shutdown.
How can I flush the memory automatically?
The basis team reported this error for us. "It is not posible to flush the memory, it is necessary to shutdown the server".
Is it posible for the oracle 9i manage the memory area (shared pool) automatically? Is it recommended? Have you got this experience?
We have seen two notes about it:
997889 --> "Increase the memory SGA the ocurrence of error ORA-04031 but it does not prevent it."
617416 --> "The following areas of the SGA can be changed dynamically with Oracle 9.2 if the SGA is configured dynamically: Buffer Cache, Shared Pool, Large Pool."
Thanks a lot.

ORA-04031 unable to allocate 4080 bytes of shared memory

Hi Everyone,
The error ORA-04031 has been consistently occuring in our production landscape.
We have Applied Oracle patches in BI7.0 (2004s - Oracle 10.2.0.2) system as per SAP's suggestions. (A set of 35 patches as per note 871096)
(Patches List - 5369855,5253307,6340979,5618049,7133360,5895190,6826661,4704890,6005996,5188321,6447320,3748430,5442919,4952782,5458753,5941030,5345999,6153847,5530958,4883635,5636728,4668719,5635254,5063279,7237154,5103126,4638550,4770693,4864648,6046043,7608184,6729801,5363584,6771608,6435823)
Applying oracle patches has not resolved this issue. The error is reoccuring. Now as per notes 1171650 and 830576 we have tuned in certain parameters.
We also checked the Notes 869006 and 1120481 but nothing much is helpful.
A Go-Live is scheduled this week. Could you please suggest what further actions need to be taken to identify the issue and resolve it.
Thanks in advance.

ORA-04031: unable to allocate 128 bytes of shared memory

Hi,
experts i need your advice here,
in my application we have on so called Master view which has 550 columns, this view is left outer join with 60 other views, something like
select c1
from   master_view
         left outer join v1 on --
         left outer join v2 on --
         left outer join v60 the compilation of the master view takes around 140 secs, but when i give grants to other users, or i re compile again, it shows me the error
ORA-04031: unable to allocate 128 bytes of shared memory plz assist me how i should resolve this issue,
Regards
nic

Hi billy,
your idea worked big big time,
i encaspulated all the outer joins views in small small views and finally build mv on each views,
the master view is plain equijoin, and has only 5 new mvs in its join condition,
the performance is increased tremendously,
thanks,
some times i wonder y i dont get such ides ;-);
all and all i can say,
good judgement comes from good experience, but good experience comes from bad judgement...
Regards
nic
