Max shmmax for 16GB Oracle SGA

Is there any damage in increasing shmmax to a max value to fit a database SGA of 16GB in memory?
Current values are below
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmseg=10
set shmsys:shminfo_shmmni=100
set semsys:seminfo_semmns=6940
set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=250

Absolutely no damage. It's a number only used when the shared memory segment is created. It's checked to see if this number is smaller than the size of the shared memory segment to be created.

Changed Ulimits values for the Oracle user and getting error -bash: ulimit: max user processes: cannot modify limit: Operation not permitted when logging in.

I'm trying to increate the ulimits for max user processes and open files for the oracle user. I've set the values in limits.conf, /etc/profile and in oracle's environment scripts. Now when I log in as oracle I get the below errors. If I change the ulimits back to the original values errors go away but ulimits aren't changed.

Thanks for the update.
I modified the /etc/security/limits.d/90-nproc.conf and added a line for oracle and also modifed the oracle.sh file. The ulimits are setting correctly when I su - oracle but they are still wrong when sshing in as oracle.

Is SHMMAX setting useful if SGA 4 GIG ?

i am setting up a SGA with 6GIG on a shared memory file system with bigpages . The SGA size will be 6 GIG while the shmmax max values can only be 4 GIG. Is there some inconsistency or at least some inefficiency with the low shmmax value ?

To my knowledge, SHMMAX can only be <3GB since 1 GB address space is reserved for the kernel on a 32-bit system. In fact, you can only allocate up to 2.7 GB of regular shared memory for SGA without tmpfs. For more information, see
http://www.puschitz.com/TuningLinuxForOracle.shtml#IncreasingSpaceForLargerSGA
http://www.puschitz.com/TuningLinuxForOracle.shtml#SettingSharedMemory
For SGA sizes > 2.7 GB you have to use tmpfs. Note however that only database buffers may reside in tmpfs. This means that all other parts of the Oracle SGA must still reside in the regular shared memory (i.e. <3GB SHMMAX, you can set SHMMAX to 3GB though, you just won't be able to use all of it).
Also, keep in mind that Oracle needs a "window" (VLM_WINDOW_SIZE) in the shared memory address space (SSHMAX) for mapping memory areas in tmpfs in and out of the VLM window.
This means:
Total SGA size - db buffer size + VLM_WINDOW_SIZE <= 2.7GB

Data size bigger than max size for this type - DB Control

All,
We are using a Java Control to fetch and store data
- it fetches data from a webservice through a webservice control
- it stores data in to database using a database control (stores the data as BLOB)
Here currently we facing an error - weblogic.jws.control.ControlException: ControlException on control databaseManager[Data size bigger than max size for this type: 4516]
The data is definitely not overshooting the max capacity of BLOB which is 4 GB. Initially this process was overshooting the transaction time-out limit of 300 sec but currently this is well within the transaction time-out limit and error happens soon after the webservice returns the data.
a. Are there any known issues with using BLOB's with database controls ?
b. what are the options - if we face this error ?

Hi Sudeep. The problem is that WLW is trying to set the datum as a byte array
and the oracle driver won't take a byte array that big. Please check whether
WebLogic Workshop has any explicit instructions for BLOB data. Otherwise, do
contact official BEA support for your WebLogic WorkShop issue.
Joe

Data size bigger than max size for this type

First, I'd like to thank you for release 1.2.1, it works like
a charm! Keep up the good work. Here are my questions:
1. When parsing a stored procedure, I get the message "Data
size bigger than max size for this type". Can you tell me what
causes this?
2. Is there any list of all the error messages that can be
given by Migration Workbench?
Thank You,

Shane,
With respect to your questions :
1. Could you possibly send [email protected] (that is
our helpdesk, a direct line into development) a little more
information about what you were doing. Also, if you could
send us the stored procedure in question (no data required)
then we could try to reproduce the error in-house and better
evaluate what is going on.
2. The majority of errors ORA-**** are actually generic
Oracle errors and can be found in the Server documentation.
As for our specific errors most parser messages can be
found in the appendix "Parser Reference" from the help system.
Regards,
Marie

From 1 DB:Data size bigger than max size for this type

I am getting error while inserting text file as a string in the table (oracle DB)as :java.sql.SQLException: Data size bigger than max size for this type: 11412
This particular column is Long data type.
The mystry is there is: In one DB instance the code is working fine without error but in other DB instance its giving the following Error:

Yes Rajat . Your are right
I have pasted the code below. I am using "String" to hold the message (strQueueMessage). That should be the problem
Pls let me know How should I overcome this problem.
public void dbWriteLog(String strQueueMessage,
               ExtractionEngineDetails objExtractionEngineDetails,
               QueryBuilder objQueryBuilder) throws DBException
objPrepStatement.setString(1,strQueueMessage);
objPrepStatement.setDate(2,new Date(new java.util.Date().
                         getTime()));
               objPrepStatement.setString(3, ExtractionUtils.getProperty(
                         ExtractionUtils.EXT_FAIL_TYPE2));
               objPrepStatement.executeUpdate();
               objPrepStatement.close();
               stmt = conn.createStatement();

Why i need all that b***s*** for installing oracle db?

As all you know to install for instance oracle 11g on redhat, oel, centos, fedora, etc... oracle recommends to install more than 600MB of garbage in the OS...
For instance if we have a minimal redhat install we would need to install more than 580 packages to run oracle. These packages are grouped in 12 groups. they are installed with yum or up2date depending on your OS version:
yum groupinstall "GNOME Desktop Environment" "Editors" "Graphical Internet" "Development Libraries" "Development Tools" "Server Configuration Tools" "Administration Tools" "Base" "Fonts" "Legacy Fonts" "Hardware Support" "System Tools" "X Window System"
Beside that we also need to make sure that the following packages are installed:
yum install binutils-2.* elfutils-libelf-0.* glibc-2.* glibc-common-2.* libgcc-4.* libstdc++-4.* make-3.* elfutils-libelf-devel-0.* glibc-devel-2.* gcc-4.* gcc-c++-4.* libstdc++-devel-4.* unixODBC-2.* libaio libaio-devel unixODBC-devel sysstat compat-libstdc++
But what's REALLY FUNNY, is that if we install a NON-PAYED version of Oracle (Oracle XE) we don't need any of the previous b***s***!!!! This is annoying, really annoying... we only need to install a sweet sweet RPM, 200MB, and e got it there...
So, anyone here can explain me (convince me) why the h*** we need to install 580 packages and at least 600MB of packages to get oracle ready to be installed?
Btw, I install oracle on linux for about 8 years, so I don't need explanations... I need to be convinced that Oracle could not do better than this... ;)

Joao

For me it makes sense to have a Just enought OS for Oracle Database to run... Despite most people refer to JeOS as beeing related to VM environment's (for instance Ubuntu JeOS) the JeOS concept is not exclusive to VM's. And it sure even makes more sense to have a JeOS for running in an VM such as Amazon EC2.
EC2 AMIs with an Oracle Database in it already exist. OEL AMIs are being worked on if they're not already there.Exists in US :) not europe...
If you take a closer look at those AMI's you surelly find at least 500MB of software installed that's not needed to run Oracle 11g. I may be wrong but the OEL5 that comes installed on those AMI's eats ~300MB of memory without database running... And for instance I have EC2 instances (fedora 8) running that only uses 65MB memory without the oracle database running... If you think that a 32bit instance in amazon has at most 1.7GB, those 240 MB makes all difference to run databases! If I use the OEL, I waste 250 MB of precious memory that I can use in my database SGA.

Pagination support for non-Oracle databases?

Hi,
I just read this thread (Pagination Support on pagination support. Is there any way to get pagination with non-Oracle databases? We are using an IBM iSeries / AS/400 DB2 database right now, and we're planning to use some local lightweight database in the near future as well (probably Cloudscape/Derby or "IBM Everyplace database".)
We currently use code like this:
String sql = "SELECT art FROM Artikel art" +
            /* dynamically generated where statement is added here */
            + "ORDER BY art.artikelNummer";
Query q = em.createQuery(sql);
q.setFirstResult(firstResult);
q.setMaxResults(maxResults);If I look in the TopLink logs, I see queries like this:
SELECT ARTNR, ARALT, ARAFJ, ARXII, ARAVJ, ARXIV, ARANJ, AHGCD, ARNVJ, ARCRJ, ARARK, ARFKJ, ARTNK, ARGP1, ASGCD, ARGP2, ARPR1, ARGP3, ARPR2, AREX1, ARPR3, AREX2, ARPR4, AREX3, ARASA, ARINA, ASSCD, ARIA1, ARBAN, ARIN1, ARBAV, ARIA2, ARBAK, ARIN2, ARCES, ARIA3, ARCDT, ARIN3, ARCRE, ARIA4, ARCWK, ARIN4, ARHBH, ARIA5, ARDFA, ARIN5, ARDFG, ARIA6, ARDOS, ARIN6, AREPW, ARINN, ARFOD, ARIAS, ARFOE, ARINS, ARFOF, ARNAB, ARFOI, ARNIB, ARFON, ARNIA, ARFOS, ARNN1, ARFTA, ARNA2, ARVIV, ARNO2, ARGAP, ARNN3, ARGPT, ARNA4, ARGPD, ARNO4, ARGPA, ARNN5, ARGPO, ARNA6, ARHIS, ARNN6, ARISP, ARNIO, ARKHM, ARNNS, MAGCD, AROVJ, MTGCD, ARPL1, ARMXM, ARPL2, MRKCD, ARPL3, ARMVR, ARVKJ, ARMIM, ARV12, ARMDT, ARVVJ, ARMTE, AR#VR, ARMTU, ARZLS, ARMTM, ARIAT, ARMWK, ARAVS, MPCCD, ARNVS, ARBTW, ARFJS, ARXI2, ARG2S, ARXI3, ARE1S, ARXI4, ARE3S, ARXI6, ARIB1, ARXI1, ARIB2, ARXI5, ARIB3, AROPI, ARIB4, ARPRV, ARIB5, SZGCD, ARIB6, ARSPC, ARINO, ARSMF, ARIOS, VEAAN, ARNIS, ARSYN, ARNO1, ARVR1, ARNA3, ARV1S, ARNN4, ARVR2, ARNO5, ARV2S, ARNIN, ARVR3, ARNOS, ARV3S, ARP1S, ARTFA, ARP3S, ARTFG, ARS12, ARUVC, ARZLD, ARUCW, ARAJS, ARBKV, ARCJS, ARVVI, ARG3S, ARVVP, ARINB, VPOCD, ARIO2, VPECD, ARIO4, ARVIH, ARIO6, ARVHG, ARNBS, ARVRW, ARNN2, ARVPR, ARNA5, ARVVR, ARNAS, ARVVS, ARP2S, ARVV1, ARSVV, ARZK1, ARNJS, ARNA1, ARNO3, ARIO1, ARNO6, ARIO5, AROJS, ARE2S, ARVJS, ARIBS, ARIAD, ARIO3, ARG1S FROM ART WHERE ((((ARUVC = 'N') AND (ARHIS = 'N')) AND (ASGCD = 7)) AND (AHGCD = 15)) ORDER BY ARTNR ASC
(Yeah, I know we have too much columns in the table...)
So, no pagination in the query. As you can see, we have a mechanism in place to dynamically generate a where clause. This is because the user can set filters. The problem is, if our user sets a filter that causes the result set to be significantly smaller, the performance is way better than when he sets no filter at all. We suppose this is because the whole result set is sent to TopLink, regardless of the values of firstResult and maxResults.
We are using TopLink Essentials 2.1-10, by the way.

Hi all,
I'm trying to subclass <tt>DatabasePlatform</tt> to add pagination support for the AS/400 DB2 database of my customer. To be fair, it is not going very well so far.
The first problem is, the query Chris found by googling (Re: Pagination support for non-Oracle databases?), does not work for AS/400s version of DB2. In fact, although it is called "DB2", the database on the AS/400 system is a whole other database than the "normal" DB2 database that runs on Windows and *nix. The AS/400 DB2 simply does not have a "ROW_NEXT" function.
Another option would be to use the <b>row_number() over()</b> mehtod. But, as can be read here, this function is only available from version V5R4 of OS/400. And guess what? We're stuck on V5R3 at this client. (We cannot upgrade, because there's an application in use that's written in Delphi and IBM dropped the Delphi binding from V5R4...)
So I pretty much ran out of options. On the mailing list I linked to above, someone mentions the option to make a sort of stored procedure that generates a row count number. An example of how to do this can be found here. I implemented it, and ended up with this code:
package com.myclientsname.persistence;
import java.sql.Connection;

import java.sql.SQLException;
import org.eclipse.persistence.expressions.ExpressionBuilder;

    public void printSQLSelectStatement(DatabaseCall call, ExpressionSQLPrinter printer, SQLSelectStatement statement) {
        int max = 0;
        int firstRow = 0;
        if (statement.getQuery()!=null){
            max = statement.getQuery().getMaxRows();
            firstRow = statement.getQuery().getFirstResult();
        if ( !(max>0) && !(firstRow>0) ){
            super.printSQLSelectStatement(call, printer,statement);
            return;
        } else {
            statement.setUseUniqueFieldAliases(true);
            ExpressionBuilder builder = new ExpressionBuilder();
            statement.addField(builder.getField("COUNTER() AS CNTR"));
            printer.printString("SELECT * FROM (");
            call.setFields(statement.printSQL(printer));
            printer.printString(") AS R WHERE R.CNTR >= ");
            printer.printParameter(DatabaseCall.FIRSTRESULT_FIELD);
            if ( max > 0 ){
                // Use of binding parameters is not allowed here, so use
                // String concatenation instead...

            //Without a connection we are unable to determine what caused the error so return false.
            //The only case where connection will be null should be External Connection Pooling so
            //returning false is ok as there is no connection management requirement
                //If there is no ping sql then we can not perform the ping.
            return false;
        PreparedStatement statement = null;
        try{
            sessionForProfile.startOperationProfile(SessionProfiler.ConnectionPing);
            if (sessionForProfile.shouldLog(SessionLog.FINE, SessionLog.SQL)) {// Avoid printing if no logging required.
                 sessionForProfile.log(SessionLog.FINE, SessionLog.SQL, getPingSQL(), (Object[])null, null, false);
            statement = connection.prepareStatement(getPingSQL());
            ResultSet result = statement.executeQuery();
            result.close();
            statement.close();
        }catch (SQLException ex){
            try{
                // Had to add this check because of NullPointerExceptions
                // (maybe a bug?)
                if(statement != null){
                    //try to close statement again in case the query or result.close() caused an exception.
                    statement.close();
            } catch (SQLException exception2) {
                //ignore;
            return true;
        }finally{
            sessionForProfile.endOperationProfile(SessionProfiler.ConnectionPing);
        return false;
}(As you can see, I had to override the <tt>wasFailureCommunicationBased()</tt> method as well, due to some unexpected NPE's. (A bug, perhaps?))
This code does work. However, the performance is not very well. The first page comes relatively fast, but as you browse further in the table, each page comes slower. I assume this is because the counter() method has to be evaluated for each row in the table.
I have to get the performance better and constant. Does anyone have an idea how to optimize this further?
Best regards,
Bart Kummel

Select Max record for the report

Post Author: ROMZILBER
CA Forum: WebIntelligence Reporting
Hello,
Here is our problem we have history data on a table like
Example
Data:
11111   bbb       12/31/2004
11111   nnn       12/31/2005
11111   ddd       12/31/2007
On a report we only need to display the most current record (based on a date).
11111   ddd       12/31/2007
How can we do that, we have try to create subquery but it does not allowed to enter logic for the max date for the same id. So we are kind of stuck, I am more then sure this would be a very common conditions specially for data warehousing.
we are on Oracle 10g
Thank you for all your help.

CA Forum: WebIntelligence Reporting
To create a view is not a problem, supporting it is a different story
But we have find a solution, you were correct about the filter. I just did not know you can put the whole subselect in a filter
but here is a logic for the filter if someone would come up with the same problem
tablename.NNNN_PROOF_DT = (SELECT MAX(X.NNNN_PROOF_DT) FROM tablename X WHERE tablename.NNNN_CLAIM_NUMBER = X.NNNN_CLAIM_NUMBER AND   tablename.NNNN_LINE_CD = X.NNNN_LINE_CD)
please let me know if you have any questions.
sorry I am new to this so please do not take any offense

Error: Data size bigger than max size for this type: 4774

Hi all,
I am using Oracle 8.1.7.I am having long datatype in one table.I installed Oracle 9i jdbc driver( ojdbc14.jar) file and using it .When i try to submit the form from web it is giving the following error
java.sql.SQLException: Data size bigger than max size for this type: 4774
The same thing worked if i use Oracle ODBC driver.

Hi,
Can you please let me know what could be the reasons for encountering the error. Am struck with this issue.

Oracle SGA Real Time Consumption Information(9i,10g and 11g)

Hello,
I need to prepare a comparative analysis report of SGA for an Oracle Production Instance
The analysis would show the pre-allocated memory to SGA components v/s real time consumption of memory by these SGA components. I need to do this for each of following components.
SGA itself
Fixed Size
Variable Size
Database Buffers
Redo Buffers
The pre-allocated memory to above SGA components can be obtained by querying v$sga. But from where do I get its real time(current) memory conusmption in Oracle Production environment.
In addition to above, i need the same information (pre-allocated and real time consumption) for following.
Keep buffer cache
Recycle buffer cache
Specific block size caches
Shared pool
Large pool
Java pool
streams pool
Which tables do I need to consider in order to derive 1)pre-allocated memory and 2)real time consumption for above mentioned SGA components
Please advice.
Thank you for your time in reading this post.
Thanks,
Ruchir

Hi,
Have a look at v$sgastat. Also, use statspack in 9i and AWR reports on 10g. Also, the size of the caches won't grow unless they are used. The parameters you have specified within the parameter file, like sga_target (10g onwards) and possibly the other pools if you have specified them, will show you what the caches can grow to.
For example, you could just log onto the DB and do show parameter sga_ or shared_pool and you will seee values for these. Also, it depends whether you are running in automatic memory management mode - where the sga_target parameter is set - or manual. 9i will be manual, but 10g could be auto. In manual case, 9i, check out the parameters individually.
Also, read the docs about the parameters shown and you will see what it says abotu them. There will be lots in the docs about performance tuning and monitoring of the instance. You might even learn some other interesting facts while reading through the docs...
Hope this helps,
Rob

Java.sql.SQLException: Data size bigger than max size for this type: 77835

I'm having this strange SQLException while trying to insert BLOB image data to Oracle database. I'm saying this strange because for the same image that has been inserted before it's throwing the exception. My program is run from Oracle form and then some image data are inserted into database through a loop. I can't realize what's the problem inside my code that's causing this problem. In fact, when I run my program independently not from Oracle Form, it runs fine, every image data get inserted into database. Given below is my code snippet:
public void insertAccDocs(String[] accessions) throws SQLException
    for(int q=0; q<accessions.length; q++)
    final String docName = accessions[q];
    dbThread = new Thread(new Runnable(){
    public void run()

Hi thanks....would you please make me a bit clear about your suggestions? Where should I move to see the "max packet size allowed to send to server in jdbc driver"? If I want to change this on server side or as one of JDBC connection property, which topic should I look for in Oracle doc...please let me know.

Max limit for Hierarchy

Hi,
The client has varying levels of people reporting levels.Some go down just three levels, others go down 14 levels.
What is robust way to model and store that hierarchy and present its hierarchy values in OBI.
Is 11 the max limit for Hierarchy?
Thanks

AFAIK, I dont think there is any thing limiting about OBIEE in terms of max. levels within a hierarchy other than the limits set by your data source (oracle has 1000 column limit AFAIK in a table).

How to set min & max connections for MSSQLconnection pool

Hi,
I want to set minconnection, maxconnection, idletimeout initial limit for the pool
I have got a MSSQL database connection using following java code.
// MSSQL DbConnection Code
import java.sql.*;
public class MsSqlDataSource
public static void main(String arr[])
Connection con = null;
ResultSet rs = null;
try{
com.microsoft.sqlserver.jdbc.SQLServerDataSource ds = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
ds.setServerName("10.50.50.51");
ds.setPortNumber(1711);
ds.setDatabaseName("test");
ds.setUser("starhome");
ds.setPassword("starhome");
con = ds.getConnection();
}catch(Exception e){}
}In oracle i have passed min and max number of connection properties through setConnectionCacheProperties method.
//Connection Pooling using Oracle Data Source:
m_connSource = new OracleDataSource();
m_connSource.setDriverType("thin");
m_connSource.setServerName(m_host);
m_connSource.setNetworkProtocol("tcp");
m_connSource.setDatabaseName(m_db);
m_connSource.setPortNumber(m_port);
m_connSource.setUser(m_user);
m_connSource.setPassword(m_password);
// Enable caching. m_connSource.setConnectionCachingEnabled(true);
java.util.Properties prop = new java.util.Properties();
prop.setProperty("MinLimit", m_minConnections);
prop.setProperty("MaxLimit", m_maxConnections);
prop.setProperty("InitialLimit", m_initialConnections);
prop.setProperty("InactivityTimeout", m_inactivityTimeout);
prop.setProperty("AbandonedConnectionTimeout", m_abandonedTimeout);
prop.setProperty("ConnectionWaitTimeout", m_connWaitTimeout);
m_connSource.setConnectionCacheProperties(prop);I dont know how to pass min and max number of connection properties for SQLServerDataSource. Is there any method available to pass min and max number of connection properties for SQLServerDataSource.
Iam using Tomcat. I found one way to set min and max connections for pool by doing changes in context.xml and web.xml using below url http://tomcat.apache.org/tomcat-4.1-doc/jndi-datasource-examples-howto.html
I dont want to touch tomcat configuration files. I need to set connection pooling properties which is independent of application server.
Please anybody give solution for this?
Thanks,
Prisha

Hi,
you need to define your database under the DB Admin tab. In the Schema objects node you'll find Sequence Implementations, and there you can definde min max values as well as caching and increments.
