Change the buffer pool of a partition LOB that underlie an XMLTYPE in a table?

Hi all

First of all, I must say, 'ALTER TABLE' grammar is ridiculously complex, and they seem to keep piles.

OK, that said, I have a table with an XMLTYPE column:
SQL> desc cs_content_xml_data
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 CSXML_GOID                                NOT NULL NUMBER(15)
 CSXML_DOC                                 NOT NULL XMLTYPE STORAGE BINARY  <<---Here's my XMLTYPE column
 CSXML_DATASET                             NOT NULL VARCHAR2(1)
 CSXML_PART_DATASET                        NOT NULL VARCHAR2(15)
 CSXML_DATE_CREATED                        NOT NULL TIMESTAMP(6)
 CSXML_USER_CREATED                        NOT NULL VARCHAR2(30)
 CSXML_DATE_MODIFIED                                TIMESTAMP(6)
 CSXML_USER_MODIFIED                                VARCHAR2(30)
In addition, this table is partitioned. Here is the generated DDL, with truncated partition definitions, for brevity:
  CREATE TABLE "MSTMFG"."CS_CONTENT_XML_DATA"
   (    "CSXML_GOID" NUMBER(15,0) NOT NULL ENABLE,
        "CSXML_DOC" "SYS"."XMLTYPE"  NOT NULL ENABLE,

        "CSXML_PART_DATASET" VARCHAR2(15) NOT NULL ENABLE,
        "CSXML_DATE_CREATED" TIMESTAMP (6) NOT NULL ENABLE,
        "CSXML_USER_CREATED" VARCHAR2(30) NOT NULL ENABLE,
        "CSXML_DATE_MODIFIED" TIMESTAMP (6),
        "CSXML_USER_MODIFIED" VARCHAR2(30),
         CONSTRAINT "CSXML_GOID_PK" PRIMARY KEY ("CSXML_GOID")

--lots of table partition definitions omitted here, for brevity
So, my question is, how to change the attribute default USER_TABLES of the PARTITION's LOB that underlies the storage of XMLTYPE column? How can I change to RECYCLE, DEFAULT value?

I tried several variants, no success, and I can't find an example in the manual or on the web anywhere.

Can anyone offer me a clue?

Help!

Thank you

-Mark

Hello

Have you tried the following?

ALTER TABLE cs_content_xml_data MODIFY LOB (CSXML_DOC.xmldata) ( STORAGE( BUFFER_POOL RECYCLE ) );

HTH.

  • How to change the Port pool

    If we want to change the port pool after cloning of layers of DB and Apps, what is the best way to do... A single method, I know, i.e run the preclone on the target system and run config clone again once on the same target on both system layer of database and Application layer and change the pool of port...

    is there another method?

    How to change the host name of a component of Applications using AutoConfig Doc ID: 341322.1

    (a) to register the application of topology of net service model node
    (b) updated the context file Autoconfig
    (c) shutdown apps services
    (d) to run the automatic configuration service
    (e) change the name of the host at the OS level
    (f) restart the machine.
    (g) to start the application sercies

    In step 2, the context of the updated file, we will create the new context with the new hostname file... Here I have doubt, how come new context file will be created with the new host name, since it has not changed hostname at the level of the bone at this stage or before this step? AutoConfig will be CNET, because the Hostname of the Machine is different, because we change the hostname in the last step before

    Please clarify my doubt, if my understanding is wrong?

    In step 2, you run "perl adclonectx.pl" command. This script is used to clone your context file (i.e. generate a new), and it will ask you to enter the new host name. Once completed, you will have two files of context in the directory $APPL_TOP/admin:

    (1) _ .xml
    (2) _ .xml

    When you run the AutoConfig (step 4), you must provide the context new file generated (i.e. _.xml), and the model topology net services (which is clean, because we have already served there) will be filled with the new host name.

    why we cannot do the procedure below...

    (a) to enter the net service topology model applications pane
    (b) change the hostname at the os level
    (c) restart the machine.
    (d) update the context file with the new host name or create the new context file
    e run the automatic configuration
    (f) to start the services

    Please correct me if I'm wrong...

    I have not tried your procedure before, but I think it would work also.

    I hope it is clear now.

  • Pinned table, the changed data. Automatic reflected in the buffer POOL?

    Hello gurus DB,.

    Question (Oracle 10 g 2) -
    1. a Table is PINNED (USER_TABLES. KEEP).
    2. in the same Table in its respective schema, data are added and updated
    (With the help of the SQL Insert and Update statements).
    Question -
    In order to take account of new data, we-
    a. the same PIN Table again.
    b. the table need not new pine
    in addition, it is said that 10g requires no PINNING objects. Is this true? If so, then to what extent?
    Warm glances,

    When you choose to use the Dungeon buffer, there is in fact no "pinning". You are just isolate the table in another buffer as all the tables on the default buffer will compete for buffer space, and all the tables on buffer Dungeon will compete on space memory buffer keep. The Dungeon of the buffer is really keep only if you size it accordingly so that the sum of the sizes of all the tables and indexes mounted on it are smaller than the size of the buffer. Otherwise, it works on a round robin like the default buffer mode.

    And Yes, if you update, insert, or delete data in the table, it appears automatically on the buffer, after all, that's what the buffer is - store the current version of the data while you wait for the db writer to empty the disk, among other things.

    You can use a function 'Add' on the output of the table. Connect the output array for an entry and a constant with your offset value to the other entry.

  • The outgoing OOME caused buffer pool increase

    Is there a way to control the maximum size of the buffer pool out (extend the proxy)? I was under the impression of the proxy service will end customer extend connections to protect out-of-memory exceptions, but in our case the buffer kept more and more until the moment where Java virtual machine ran out of memory directly.

    HI -.

    The OOME is a result of the execution with the suspect disabled protocol.

    The suspect Protocol protects the proxy running out of memory because of the slow clients.
