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.

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
nicHi 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...

ORA-04031: unable to allocate 33568 bytes of shared memory in Oracle 10g
Hi,
I am getting following message frequently while taking export in Oracle 10g database:-
EXP-00008: ORACLE error 4031 encountered

Whats could be the reason?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

ORA-04031: unable to allocate 4096 bytes if shared memory
Hello Gurus,
Did anyone got this type of error before:
ERROR:
ORA-20414: Materialized View refresh failed - ORA-12008: error in materialized view refresh path
ORA-04031: unable to allocate 4096 bytes of shared memory ("shared pool","IDX_MIF_SITE","pacdHds_kkpaco","stP_kkpacd: kkpodPacdInit")
Every sunday full refresh of the data warehouse is scheduled. This sunday it didn't complete and gave us the above error. This can be solved by increasing the shared pool memory size. But DBA doesnot want to increase it every sunday(This has been going on for 3 weeks now) and it's not feasible to increase like this everytime.
We want to find the actual cause of it and fix?
Does anyone know the solution or can throw some light on this issue?
Thanks,
SanjayWe want to find the actual cause of it and fix?The cause is simple - you have run out of memory assigned to the Shared Pool in the SGA.
The root cause is more of an issue. The Shared Pool is mostly used for keeping the SQL statements and supporting information (such as cursor support). Each unique SQL statement requires it's own area in the shared pool, however identical statements can used the same (shared) area. Shared Pool is also used to store the 'current' data dictionary (table, view, etc.) information. And in some cases, it's also used for 'large' operations such as direct path insert block builds.
Some of the possible reasons for running out of shared pool might include
- it's simply undersized;
- not enough SQL is actually shareable;
- the large pool has not been allocated.
That second one is frequent when the application builds up SQL statements by concatenating pieces, including literals (user input) and then executing the unique statement. This is a common technique by developers using .Net, Perl or having SQL Server background. (That mode of operation is very susceptible to SQL Injection.)
You can get a lot more info from:
- searching the forum;
- looking in the docco (Concepts manual and Performance Tuning guide);
- books, like Tom Kyte's "Expert One on One Oracle", "Effective Oracle By Design", and newer on apress.com -

Hi Guru's
Could some one help me in finding the sql's/program which causing the ora-04031 unable to allocate 3896 bytes of shared memory.
any suggestion is highly apprciated
Kind RegardsYou may want to take look at:

Cause: More shared memory is needed than was allocated in the shared pool.
Action: If the shared pool is out of memory, either use the DBMS_SHARED_POOL package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memory by increasing the value of the initialization parameters SHARED_POOL_RESERVED_SIZE and SHARED_POOL_SIZE. If the large pool is out of memory, increase the initialization parameter LARGE_POOL_SIZE. -
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.

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.

Cause: More shared memory is needed than was allocated in the shared pool.
Action: If the shared pool is out of memory, either use the dbms_shared_pool package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memory by increasing the value of the INIT.ORA parameters "shared_pool_reserved_size" and "shared_pool_size". If the large pool is out of memory, increase the INIT.ORA parameter "large_pool_size".

ORA-29855 - Unable to allocate shared memory
Hi,
We are encountering troubles (unable to allocate shared memory) while indexes creation. We tried to increase the share_size_memory (actually 52 mb) but this had no effect on this error. The Oracle error code is ORA-29855.
The database is version 8.1.7, hosted on a Linux machine (RedHat 7.2) with 512 mb of memory. The code used for the index creation works fine on other machines (code from 9iAS Wireless installation) running with Windows 2000 as operation system.
Any help or comment will be appreciated.
Thanks,
Fabrice Clari.
The error message is:
java.sql.SQLException: ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine

I have an error ora-04031 on XE 11g
hello,

When I restart DB, this error is fixed.
Can I set any parameter(SHARED_POOL_SIZE) to fixed this error?

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.

ORA-01659: unable to allocate MINEXTENTS beyond 9 in tablespace
Hi all
I received database dump from client and I am trying to Import into our database. I created tablespace and while trying to import, I am getting below error
ORA-01659: unable to allocate MINEXTENTS beyond 9 in tablespace <>
I increased the Size of the tablespace up to to 6gb still getting the same error.
what I received is only structure without data. still why It's needed much space.
My doubts are :
1) How to know what is the size required to complete the dump
2) s there any option to take export which can take less space when I import?
My plan is not to replicate the DB but only to import the structure in a schema.
We don't have a DBA so I am doing this task

ORA-04301:Unable to allocate 8144 bytes of shared memory

I am randomly getting this error. The full error message is below:
ORA-04301:Unable to allocate 8144 bytes of shared memory("large pool","COMPANYHISTORY","kxs-heap-w","qesaQBinit:buffer")
The table name keeps changing as the queries change. Similarly sometimes instead of "large pool" I get "shared pool" in the above message.
I tried increasing the shared pool size but the problem did not resolve.
Please help

MadhupI have already tried that, but I am not able to solve the problem. Is there a way to compute how much space you should define for the shared pool, the large pool etc.
