One way is use db_block_size like 16 K
thanks in advance,

From Show parameter nls_length_semantics
We come to know its --> nls_length_semantics CHAR
Will below solution works ?

ORA 01450 : maximum key length (1942) exceeded

hI all,
i got that message when try to create index.
ORA 01450 : maximum key length (1942) exceeded
Regards,

Maximum key length also depends on tablespace block size. It seems that your value (1942) may be for 2K blocks.
At least for my 10.2.0.1.0 on Windoze it takes
1478 for 2k tablespace
3118 for 4k tablespace
6398 for 8k tablespace
If you have 2K blocks I'd say it is somewhat rather small blocks, I'd normally use 8K blocks.
So if you have possibility (have at least version 9, probably 9.2 don't know exactly) to create tablespaces with non default blocksize then as a temporal solution you can create tablespace with larger blocksize and create index in it.
Of course so you have to allocate also some memory for these blocksizes and so divide your memory in possibly less utilized pieces.
See example for my 8k default blocksize test DB:
SQL> create table v (a varchar2(4000), b varchar2(4000), c varchar2(4000));
Table created.
SQL> insert into v values (lpad('a', 4000, 'a'), null, null);
1 row created.
SQL> create index vidx on v (a, b, c);
create index vidx on v (a, b, c)
ERROR at line 1:
ORA-01450: maximum key length (6398) exceeded
SQL> alter system set db_16k_cache_size = 10240;
System altered.
SQL> create tablespace big datafile 'big.dbf' size 10 m blocksize 16k;

Cloning problem: ORA-00059: maximum number of DB_FILES exceeded

Hi everyone!
I'm trying to clone our data warehouse over an existing test instance, DMART01. Here's what I did:
1. on the data warehouse - alter database backup controlfile to trace;
2. edited the trace file to change the db name and path of the datafiles
3. logon to sqlplus in DMART01 and run my altered trace file.
4. Below is the error I'm getting:
SQL> @clone09142009.sql
ORACLE instance started.

MAXLOGFILES 16

Additional information - the data warehouse has an entire tablespace with many datafiles that I don't want in DMART01. I edited those datafile lines out of my trace file. Could some remnants of that be causing my problems? The DB_FILES parameter in the warehouse is set to 500. In DMART01 it's only 200. In the clone, I only want to bring over 61 datafiles. Besides, I thought that in the create controlfile statement would set the parameter, in this case to 500.
I'm stumped. Any suggestions?
Thanks!
Sharon

I answered my own question. If anyone is curious, here's what I did:
in DMART01
1. startup nomount;
2. create pfile from spfile;
3. shutdown immediate;
4. edited pfile to have dw_files=500
5. startup nomount pfile=initDMART01.ora;
6. create spfile from pfile;
7. shutdown immediate;
8. @clone09142009.sql

Ora-00020 maximum no .of connections exceeded

Hi All,
I tried to connect the production Db is says Maximum number of connections exceeded.
How to overcome this situation.
I stoppped and bounced the Db.
The process paramter in pfile is 50
Is there any to overcome this

c:\sql>oerr ora 00020
00020, 00000, "maximum number of processes (%s) exceeded"
*Cause: All process state objects are in use.
*Action: Increase the value of the PROCESSES initialization parameter.
Increasing the PROCESSES parameter as suggested by the error information would remove the issue.
If the database has been working fine for an extending period of time without this error you should consider finding out what caused the increase so you can set parameter appropriately. Could be an increase in use or an application leaking connections.

ORA-Error: Maximum number of Processes exceeds

Hi,
Today we got one Oracle error: Maximum number of Processes exceeds while connects to our Oracle Database.
We have application running on our DB, which have 50 threads running and making connection to Oracle Schema.
In our init.ora file the Processes Parameter is set to 50.
But we also have another init<Schema Name>.ora file which has Processes Parameter as 50.
When I search on this error, I got that it is due to no. of user processes on Oracle instance.
What are these user processes exactly?
If we set the Processes Parameter as 150, and we have RAC environment with 3 Cluster, does it means we have 150*3 processes can run at a time.
The other doubt I have is that: Is this parameter is instance based, SID based or cluster based?
Please provide some input on this.
Thanks in Advance.
Manoj Macwan

If you don't issue
alter system set processes=150 scope=both sid='<your instance 1>'
all instances will be allowed to fork 150 processes.
The other poster is incorrect.

ORA-31005: Path name length 3125 exceeds maximum length 1024

what does this error mean?
how to resolve it and how to track where it is occuring.
it is a xml parsing error but which path is it talking about?
str_sqlstring contains xml in string format.
xmlvar := xmltype('ROOT',str_xmlstring);
doc := dbms_xmldom.newDOMDocument(xmlvar);
ndoc := dbms_xmldom.makeNode(doc);
dbms_xmldom.writetobuffer(ndoc, str_buffer);

Function Based Index and ORA-01450

The following DDL produces ORA-01450 (maximum key length (758) exceeded) :
create index test_fn_ix1 on ausv_int_acc (test_package.test_function(intacc_username));
Here's the package :
create or replace package test_package
is
function test_function (value_in varchar2) return varchar2 deterministic;
end test_package;
create or replace package body test_package
is
function test_function (value_in varchar2) return varchar2
is
begin
return ''| |value_in;
end test_function;
end test_package;
Obviously this is only a test function but I have a real function I want to use - I have just tried to simplify the problem.
How does Oracle know how long the function result is ? - it doesn't because you can't specify return length of a function, just the type !
I have got round this problem thus :
create index test_fn_ix1 on ausv_int_acc (substr(test_package.test_function(intacc_username),1,100));
Surly there's a tidier way ???
Thanks for any help

Hi,
You can add SUBSTRs, like this:
CREATE UNIQUE INDEX addresses_uq1
       ON addresses ( UPPER( SUBSTR (REGEXP_REPLACE( STREET1,'([^[:alnum:]])',''), 1, 50) ),
                      UPPER( SUBSTR (REGEXP_REPLACE( STREET2,'([^[:alnum:]])',''), 1, 50) ),
                      UPPER( SUBSTR (REGEXP_REPLACE( CITY,   '([^[:alpha:]])',''), 1, 50) ),
                      COUNTRY_CODE,
                      STATE_CODE );Why?
Try this:
CREATE OR REPLACE VIEW view_x
AS
SELECT UPPER( REGEXP_REPLACE( STREET1,'([^[:alnum:]])','') )     AS street1
FROM     addresses;
DESC     view_xYou'll see that view_x.street1 is VARCHAR2 *(4000)* .
You and I know that the REGEXP_REPLACE function is taking a 50-character (max) string, and, if anything, reducing its size. But the system doesn't figure out what REGEXP_REPLACE is doing; for all it knows, REGEXP_REPLACE could be returning any VARCHAR2, so it allows room for the biggest possible VARCHAR2.

ORA-01450 when trying to create index on xmltype column

Hi,
I have a table that contains an xmltype column. It is a schema-based column and uses object-relational structured storage. When I tried to create an index like:
create index ssual_sipuser_idx on ssua_line (extractValue(ssual_configuration, '/ssuaLineApplication/sipUser'));
I got the following:
ORA-01450: maximum key length (3118) exceeded
The sipUser tag is of string type. I have also tried creating the index on the extract function.
create index ssual_sipuser_idx on ssua_line (ssual_configuration.extract('/ssuaLineApplication/sipUser/text()').getStringVal())
Gave me the same error message. My database block size is 4k. This is Oracle 9.2.0.4 running on Solaris.
Any help will be appreciated.
Thanks,
Gloria

Thanks for the reply, Coby.
My field is really small, probably around 10 bytes. Actually I've been testing on two servers, a 9201 and a 9204. I know that Oracle doesn't support XML DB on 9201 anymore but our company hasn't switched over yet. Anyways, here's really what I saw:
9201
- creating an index with extractValue() or extract() doesn't work
9204
- extractValue() works
- extract() still doesn't work
Now I'm using the substr() workaround. I should also mention that extractValue() with a numeric field works (using getNumberVal()).
I wonder if specifying the field length in the XML Schema would make a difference. I may try that next.

Sees ora-01450

Whilst executing scripts to create tables, indexes, users for Oracle 8.1.7, i get an error that index size cannot exceed 1578 in table web_app_url. Sees ora-01450.
What does ora-01450 mean? Am i creating an index greater than a certain predetermined limit?
any info is appreciated, thanks.

Hello,
For this example we'll need user with default tablespace with block size 8 kB and another tablespace with block size 2 kB.
This is what happen:
-- default tablespace is created with block size 8 kB and table wil be created in this tablespace
CREATE TABLE BATCH_JOB_INSTANCE1 (
     JOB_INSTANCE_ID NUMBER(38) PRIMARY KEY ,
     VERSION NUMBER(38),
     JOB_NAME VARCHAR(100) NOT NULL ,
     JOB_KEY VARCHAR(2500)
-- in our case, table was filled with data, important is this:
select max(length(job_name)), max(length(job_key)) from batch_job_instance
MAX(LENGTH(JOB_NAME)) MAX(LENGTH(JOB_KEY))
21 52
-- as we can see, index will be not wide ...
-- now create index ...
-- index will be also created in 8 kB tablespace
CREATE INDEX IDX_BATCH_JOB_INST$JNAMEKEY1 ON BATCH_JOB_INSTANCE1 (JOB_NAME, JOB_KEY);
-- we'll try rebuild index to tablespace with 2 kB and Oracle is OK with that ...
alter index IDX_BATCH_JOB_INST$JNAMEKEY1 rebuild tablespace index2kB;
-- it's interesting, because index length is 2500 + 100 which is obviously more than 1478
-- let's continue ...
-- some cleanup
drop INDEX IDX_BATCH_JOB_INST$JNAMEKEY1;
-- now we try create same index but this time we'll specify tablespace name
CREATE INDEX IDX_BATCH_JOB_INST$JNAMEKEY1 ON BATCH_JOB_INSTANCE1 (JOB_NAME, JOB_KEY) TABLESPACE index2kB;
... and here we go ...

RCU - getting error ORA-01450

Hi there
When trying to install OBIEE I get an error saying that "maxium key length exceeded". It gives out the error ORA-01450. The funny part is that I have installed a couple of development environments now, without any problems - and now suddenly this? I have used the same Oracle Instance, and had success with two different RCU installs, and then suddenly no more...
Any ideas?
Regards Jacob

Jacob,
I wonder if you have ran the RCU multiple times on the same machine to create several schemas for OBIEE (BIPLATFORM / MDS).
Either way the error message ORA-01450 mainly has to do with the Database Block Size.
See these links for reference reading:
http://www.dba-oracle.com/t_ora_01450_maximum_key_length_exceeded.htm
http://www.dbasupport.com/forums/archive/index.php/t-23148.html
You will most likely need to increase your DB Block Size in order to fix this issue. Here is a link with great explanation and some PL/SQL commands on how to increase the size, [http://www.oradbpedia.com/wiki/Increase_the_Database_Block_Size|http://www.oradbpedia.com/wiki/Increase_the_Database_Block_Size] . Try that and then re-run the RCU.
Depending on which value you have in the max key length message you should go to the next block size.
ORA-01450 maximum key length (758) exceeded -> (2K Block)
ORA-01450 maximum key length (1578) exceeded -> (4K block)
ORA-01450 maximum key length (3218) exceeded -> (8K Block)
ORA-01450 maximum key length (6498) exceeded -> (16K Block)

Install HRCS9.0 and PT8.53 with Linux Issue: the files intiPT853.ora and initHRCS90.ora: maximum number of DB_FILES exceeded

Folks,
Hello. I have installed PeopleTools 8.53 with Oracle Linux 5.10 successfully. The entire PeopleTools runs correctly in browser at the beginning.
After I set up HCM and Campus Solution 9.0 Database Instance named HRCS90 in Linux successfully, PeopleTools 8.53 Database Instance PT853 cannot be mounted. Its error message is below:

But after set up another instance HRCS90, the above error message comes up and instance PT853 cannot mounted. I change the value of db_files from 1021 to 1500 in the file initPT853.ora and restart OS Linux. But get the same error as below:

As we see above, the instance HRCS90 works corretly and PT853 cannot start up. The parameter DB_FILES of the file initPT853.ora has an issue.
My question is:
Because 1021 and 1500 are not enough to startup instance PT853, what value should be used for DB_FILES of the file initPT853.ora ?
Thanks.

I'm sorry, but I don't understand what does "Instance" mean here.

Are you not using a spfile ? Does the file contain really the 3 values ? What is the last ? Have you checked the value in the database side "show parameter db_files" ?
>But after set up another instance HRCS90, the above error message comes up and instance PT853 cannot mounted
Again, I have no idea what it means.

Again, 3 values ? What is the last ? Have you checked the value in the database side "show parameter db_files" ?

Again, I don't understand what are HRCS90 and PT853 exactly. Cannot help.

I'm sure, you don't have an issue with this parameter, 1500 files in the database is quite huge number. I built a demo recently, the default value 1021 was ok for me. You should have done something wrong somewhere.

Primary Key Lengths

Hi,
What is meant when someone says that your primary key length is too long??? This error I keep getting is really annoying me and I want to understand why it does this. Thanks everyone

Is this someone the database, one of your pals at the office, or your DBA?
If the someone is the database, what is the Oracle error number you see? Could it be ORA-01450? If the error message is ORA-01450, then you are trying to create a key with a length that is too long for the server software. I think the error message will tell you what the maximum key length is for your Oracle software version / operating system.
If it's one of your pals at the office, find some polite way to tell him to go suck an egg.
If it's your DBA, then listen to your DBA because DBAs know everything.

Dynamic Configuration key length

I am using dynamic configuration to set certain JMS properties but it appears that the maximum key length is 20 characters.
Has anyone experienced this problem. Is this a bug?
Thanks
Here is my code
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/JMS", "com_inforecord_messageProcessor");
conf.put(key1, "SoapMessage");

Yes, is possible.

ORA-00018 maximum number of session

Hello:
We have a strange problem with a sql statement that when is invoked inside a php or asp program generates the following error:
ORA-00018 maximum number of session
We are using Oracle 9i installed over Red Hat with IIS 5.0. This query works fine in sqlplus. The query is:
select * from vnoticias_p WHERE contains(titulo, '" . $nom . "') > 0
titulo is a context type index formed with two concatenated fields.
The problem had caused serious problems for us, because hangs our server every time the script is being executed.
We ran this script only with one user connected, and we don´t understand how this query generates too many sessions?
Appreciate your help
Thanks

Thanks for update.
It is supposed that PROCESSES is the default value during installation. I don't know what is the default PROCESSES value of Oracle 11g in Solaris 10. Can you tell me so that I can correct SESSIONS?
During Oracle 11g installation on Solaris 10, why did I get the following errors?
ORA-12801: error signaled in parallel query server P072
ORA-00018: maximum number of sessions exceeded
ORA-06512: at "SYS.UTL_RECOMP", line 629
ORA-06512: at "SYS.UTL_RECOMP", line 671
ORA-06512: at line 1
What is the best method to solve the above problem for Oracle 11g installation?
SPFILE can not be modified manually. "ALTER SYSTEM " is one way. When I create another new Oracle instance, new Oralce instance uses the default PREOCESSES value or new PROCESSES value which I changed by "alter system"?
Thanks,
