I have a package when it runs, it terminates with "unable to allocate 4120 bytes of shared memory"error at a particular INSERT statement. So everytime we had this error, we had to flush the shared pool area, after which it would run without issues(for 3-4 weeks).
It had a dynamic subpartition clause framed, which made it to repharse the query every time.So to reduce this, we removed the subpartition clause(made it to static query), which did benefit of not getting shared pool error.
I would like to find the current shared pool memory usage of my program.Is there a way I could find the live consumption of shared pool area of my program(pkg).
I am working on Tuning a Materialized view. I was getting an error saying ORA-12008: error in materialized view refresh path
ORA-12801: error signaled in parallel query server P002, instance hrms-stg-db01:HRSTG1 (1)
ORA-01652: unable to extend temp segment by 16 in tablespace TEMP1.
so i increased the temp size. I am trying out various hints to get it rectified. But i am not sure if i should go for less cost or less bytes.

I am using compress partition for a large table.During the process I have used the below command for compress---
1. ALTER TABLE <TABLE_NAME> MODIFY PARTITION P1 COMPRESS;
However I found there are different command as below:-
2. ALTER TABLE <TABLE_NAME> MOVE PARTITION P1 COMPRESS;
What is the basic difference between these two as the compression is happening for both command.

View 5 Replies View RelatedWHAT IS THE DIFFERENCE BETWEEN ORA ERROR AND LRM ERROR?
View 9 Replies View Relateddifference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.
I've migrated from Oracle 9i to Oracle 11gR2, when i'm checking my application on Oracle 11gR2, i found that some of the query result are differed from the previous version of Oracle 9i, which is very illogical to me. I've checked the data for all related tables which are involved in one of the query. I've checked all indexes also. Still i'm not convinced that Oracle is doing anything wrong. I cannot recreate the whole scenario here, because of many tables involved in that query.
One of the sample query code.
select 'ProductMaster' producttype,e.schemecd,e.SCHEMESHORTDESC as SCHEMEDESC,to_char(e.schemefrdate,'dd/MM/yyyy')as schemefrdate, to_char(e.schemetodate,'dd/MM/yyyy') as schemetodate,e.mkid ,e.countrycd,e.statecd,e.districtcd,f.schemetype, a.productcd,a.packsizecd,a.packtypecd,a.sortorder1, a.countrycd,a.statecd,a.districtcd,a.p_uniqueid,a.mrp, (a.productcd ||'-'||b.countryname||'-'||c.statename||'-'||d.districtname|| ' -pkt.prc:'||a.pktprice ||' -mrp:'||a.mrp) as pcode

I've a question regarding difference of character sets, while taking a export(logical backup) of database on directly to server(linux RHEL 2.1 AS) and export on a client (windows xp prof machine, where only a oracle 9i client is installed). On server it seems to fine and okay, but on client node i'm getting following error for almost all tables.
EXP-00091: Exporting questionable statistics.
My question is :
[1] Is it creating any sort of problem, if later on i import the data which was taken from client node.
[2] Why there is a difference(marginal) in dump(.dmp) file size.
[3] Is there any way to overcome it, or it is the natural behave of it. Means not a problem.
[4] If i'm using a long or blob as datatype for some of my table,is they have any problem if i persist like above.
Additional Information about character sets On server node :
Export done in US7ASCII character set and AL16UTF16 NCHAR character set server uses WE8ISO8859P1 character set (possible charset conversion)
On client node :
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set server uses US7ASCII character set (possible charset conversion)

Recently i've migrated from Oracle 9i SE(9.2.0.1.0) to Oracle 11gR2 EE(11.2.0.1.0). Previously i'm taking export of some of my schema and it's file size was around 1g.(with exp utility of Oracle 9i). As per earlier practice now i'm taking export of same schema with same no of objects and same data volume, the size of export file size on Oracle 11gR2 database is significantly gone down , actual size around 825mb(with expdp utility of Oracle 11g).
So i would like to know why there is a difference in file size(.dmp files) of export files between two oracle versions. I have crosschecked objects and rows of data tables. It is perfectly same.
Command line parameter for export on Oracle 9i
exp test/test FILE=test.dmp OWNER=test GRANTS=y ROWS=y COMPRESS=y LOG=test.log
Command line parameter for export on Oracle 11g
expdp test/test DIRECTORY=dpump_dir DUMPFILE=test.dmp LOGFILE
=test.log
Currently I am doing one Oracle installation.But very much confused where to start from. Since I am installing oracle on my personaly Laptop,do I need to install Oracle database server and Oracle client both or only installing database server is sufficient.
What is the exact difference between oracle database server and client.Only knowledge I have is that client is used to access database server remotely.are Oracle database server and client installable to be downloaded separately?

What’s value of parameter I need to set for datastore, pfile ? (I have 13GB of memory).
Windows 2003 Server Enterprise Edition, Service Pack 2. 3.5GB RAM.Two Oracle Databases running on this server, one not heavily used. On the database i am concerned with it is 10.2.0.3.0.
I have just started to look at this database and am seeing various things in the alert log and have had user error messages as well.Initially when i started looking at this server it was running with quite a small SGA (600MB) and the memory_target_advice was saying to take it to 1000MB.(PGA is around 200MB)
In January, before i looked at it, it started to throw:
ORA-04031 unable to allocate 16 bytes of shared memory ("shared pool","........", "sql area", "tmp") These would occur regularly and mostly during nightly processes, it seems, and thus not bubbling up to users.Having switched the SGA_MAX_SIZE to 1GB a new set of errors starts to appear in the alert log:
ORA-27301: ..... Not enough storage is available to process this command
ORA-27302: ..... ssthrddcr
At the same time the ORA-04031 errors start to bubble through to the users. Before i could return to the scene of the crime someone else set the SGA back to 600MB and the error messages stopped. However the ORA-04031 message start to reappear in the alert log. My questions are many and, mostly, from a lack of knowledge ;) In particular:
1. Why would increasing the SGA lead to a different memory error? I would assume this would have something to do with the amount of memory a 32bit OS will allow a single process to address but the PGA+SGA is only 1200MB.
2. How does a ORA-273xx error end up with a ORA-04031 being shown to the users? I would look at the listener log but its over 2GB!!!
on 11G R2 on Win 2008,
We had the following error in alertlog repeatedly from 5 PM to 10 PM :
ORA-04031: unable to allocate 32 bytes of shared memory ("shared pool","SELECT VERSION FROM PSVERSIO .....Since MEMORY_TARGET is defined in spfile then shared pool is managed automatically.
Then what to do to avoid this error in future ?
