Sep 24, 2008Recently I came across this issue, which gives me an error as following.
ERROR:
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 4907, maximum: 4000)
Now I am running a very simple query against one of the View in our Database.
Query is:
Select Prj_Num,
PM_Comments
From ProjectDetails
Where Rel = ‘2008 10’
What I have discovered so far is one of the field in this view name “PM_Comments” has more than 4000 bytes of information in it, Which is not supported by tools I have available on my computer. I have Oracle SQL Plus, SQL plus Worksheet, Access and Excel installed on my machine. DBA related to this database are stating that the field is working fine and query is executing without error since they are using TOAD for SQL, which does have capabilities to read more than 4000 bytes.
What I have figured out so far is “PM_Comments” is a LOB and SQL plus is having trouble reading this information more than 4000 bytes in one field of information.Because of this diagnosis, I have tried using following queries but it did not useful either.
Select Prj_Num,
Substr (PM_Comments, 1, 4000)
From ProjectDetails
Where Rel = ‘2008 10’
Select Prj_Num,
DBMS_LOB.Substr(PM_Comments, 4000, 1)
From ProjectDetails
Where Rel = ‘2008 10’
But both of the above mentioned queries did not work either. and I get the same ORA-22835 Error.I do not need all of the information in “PM_Comments” field, I only need about first 1000 characters of it.

Existing Database (11.2.0.3) Can Be Upgraded As Pluggable Database And Plug It In CDB?
Sep 11, 2013I would like to know about oracle 12c. In 12c, when i read documents,i understood that one container DB(CDB) can contain upto 253 pluggable DB and this pluggable DB(PDB) is similar to our traditional database(pre 12c).
1) whether my existing database (11.2.0.3) can be upgraded as pluggable DB and plugged it in CDB?
2)i read that we can move from local data center model to cloud in this version. Is that mean that once PDB is ready, whether we can plug it in CDB using private cloud or public also possible?
3)If public cloud is possible, are both CDB and PDB accessed through cloud client only?If so, whether our user data that is available under PDB also moved to external place?

ORA-04031 Unable To Allocate 16 Bytes Of Shared Memory
May 17, 2013Windows 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!!!

SQL & PL/SQL :: Order Of Bytes Returned By Dump() Function In Reverse Key Indexes?
May 28, 2013Oracle Version: 11gR2: 11.2.0.1.0 - 64bit
OS: Linux Fedora Core 17 X86_64
Currently, I'm reading the online book Oracle Concepts, Chapter 3: 3 Indexes and Index-Organized Tables, section: Reverse Key Indexes in order to understand this topic.
As I understand for each pair of (key, rowid) in the index structure, the rowid for each row in the table obviously remains the same but the bytes of the key are reversed before the key is stored. So for example on a 32 bit machine (just an example) a key = 10 AB CD EF will be stored as FE DC BA 01 , am I right?
According to the documentation, this becomes interesting in RAC environments in order to remove a hot spot from the index (when multiple instances repeatedly modify the same block) with the disadvantage that in some cases there cannot be Index Range Scan any more as data in the index is not sorted by column key when it is stored.
I was just curious to see how bytes of each key are reversed and after a bit googling I found an article where Tom Kyte shows with an example by using dump function (which as I understand gives the internal representation of a given expression) the difference in the sequence of bytes. Here is the link
[URL]
So based on his instructions I tried to do my own test, yet I don't get the same result, that is, the bytes are not reversed for me once we rebuild the index by REVERSE key word.
I'm going to write down here the test that I did, where is/are my error(s)
Test Case:
(I use a copy of the employees table in hr sample schema)
SQL> CREATE TABLE emp_test AS SELECT * FROM hr.employees;
Table created.
SQL> CREATE INDEX emp_test_idx ON emp_test(first_name);
[code]...
Now, a test SQL Query using the index we've just defined (just for giving an example)
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
FIRST_NAME DUMP_RESULT
-------------- ----------------------------------
Kelly Typ=1 Len=5: 4b,65,6c,6c,79
[code]...
So, according to the above Execution plan, Oracle does an Index Range Scan using the index that I defined on my table that is, emp_test_idx. According to the output of dump, the key (first_name) in that index is stored (in terms of bytes) as 4b,65,6c,6c,79
SQL> SELECT chr(to_number('4b', 'xx')) ||
2 chr(to_number('65', 'xx')) ||
3 chr(to_number('6c', 'xx')) ||
4 chr(to_number('6c', 'xx')) ||
5 chr(to_number('79', 'xx')) first_name
6 FROM DUAL;
FIRST_NAME
--------------------
Kelly
Which as we can see corresponds to the first name 'Kelly', the first name we specified in the above SQL query.
Now let's rebuild the index
SQL> ALTER INDEX emp_test_idx REBUILD REVERSE;
Index altered.
SQL>
Once the index keys have been reversed, I run the very same query in order to see the difference
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
[code]...
So the second time after the index has been reversed, I still get the very same sequence of bytes, that is, 4b,65,6c,6c,79, whereas I expected to get 79,6c,6c,65,4b (that is, the reversed order of the initial bytes sequence)
