For example to enable event 10046 level 8 in a session with SID 9 and serial number 29 use

    EXECUTE dbms_system.set_ev (9,29,10046,8,'');

To disable event 10046 in the same session use

    EXECUTE dbms_system.set_ev (9,29,10046,0,'');

oading average 在 HP-UX 的定義是 : the average number of jobs in the run queue over the last 1, 5, and 15 minutes for the active processors.

即使系統沒有 run 任何的 ap, 因為有 OS 的 process 在執行, 所以 loading average 不會為 0

一般來說, 我們是透過觀察 loading average , 來衡量 CPU 是否 loading 過重. 如 loading average 為 CPU 個數的 2 倍以下, 則 CPU performance 佳, 如超過 3 倍, 即使還有 idle , 此時系統 performance 已經很糟了

1.?
Physical standby on disk database structures must be identical to the primary database on a block-for-block basis, because a recovery operation applies changes block-for-block using the physical ROWID. The database schema, including indexes, must be the same, and the database cannot be opened (other than for read-only access). If opened, the physical standby database will have different ROWIDs, making continued recovery impossible.

Eliminating Migrated or Chained Rows in a Table
You can use the information in the CHAINED_ROWS table to reduce or eliminate migrated and chained rows in an existing table. Use the following procedure.

Use the ANALYZE statement to collect information about migrated and chained rows.
ANALYZE TABLE order_hist LIST CHAINED ROWS;


Query the output table:
SELECT *
FROM CHAINED_ROWS
WHERE TABLE_NAME = 'ORDER_HIST';

OWNER_NAME  TABLE_NAME  CLUST... HEAD_ROWID          TIMESTAMP
----------  ----------  -----... ------------------  ---------
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAA  04-MAR-96
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAB  04-MAR-96
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAC  04-MAR-96

#########################################################################
The output lists all rows that are either migrated or chained.

If the output table shows that you have many migrated or chained rows, then you can eliminate migrated rows by continuing through the following steps:
Create an intermediate table with the same columns as the existing table to hold the migrated and chained rows:
CREATE TABLE int_order_hist
   AS SELECT *
      FROM order_hist
      WHERE ROWID IN
         (SELECT HEAD_ROWID
            FROM CHAINED_ROWS
            WHERE TABLE_NAME = 'ORDER_HIST');


Delete the migrated and chained rows from the existing table:
DELETE FROM order_hist
   WHERE ROWID IN
      (SELECT HEAD_ROWID
         FROM CHAINED_ROWS
         WHERE TABLE_NAME = 'ORDER_HIST');


Insert the rows of the intermediate table into the existing table:
INSERT INTO order_hist
   SELECT *
   FROM int_order_hist;


Drop the intermediate table:
DROP TABLE int_order_history;


Delete the information collected in step 1 from the output table:
DELETE FROM CHAINED_ROWS
   WHERE TABLE_NAME = 'ORDER_HIST';


Use the ANALYZE statement again, and query the output table.
Any rows that appear in the output table are chained. You can eliminate chained rows only by increasing your data block size. It might not be possible to avoid chaining in all situations. Chaining is often unavoidable with tables that have a LONG column or long CHAR or VARCHAR2 columns.

DROP
dropping and re-creating a table or cluster, all associated indexes, integrity constraints, and triggers are also dropped, and all objects that depend on the dropped table or clustered table are invalidated. Also, all grants for the dropped table or clustered table are dropped.
CAN'T ROLLBACK
TRUNCATE
Using the TRUNCATE statement provides a fast, efficient method for deleting all rows from a table or cluster. A TRUNCATE statement does not generate any rollback information and it commits immediately. It is a DDL statement and cannot be rolled back. A TRUNCATE statement does not affect any structures associated with the table being truncated (constraints and triggers) or authorizations. A TRUNCATE statement also specifies whether space currently allocated for the table is returned to the containing tablespace after truncation.
A hash cluster cannot be truncated, nor can tables within a hash or index cluster be individually truncated

Attempts to load the default media management library. The filename of the
default library is operating system specific. On UNIX, the library filename is
$ORACLE_HOME/lib/libobk.so,withtheextensionnamevaryingaccording
to platform.:.so,.sl,.a, and so forth. On Windows NT the library is named
%ORACLE_HOME%\bin\orasbt.dll.

To integrate the media manager on UNIX:
1. Ifanoldlibobk.sosymboliclinkalreadyexistsin$ORACLE_HOME/lib,then
remove itbefore installing the media manager. For example:
% rm $ORACLE_HOME/lib/libobk.so
2. After installation, check your media management vendor documentation to
determine where the media management library is installed. For example,
suppose that the library is installed as/vendor/lib/oracle_lib.so.
3. Either change the name of the installed media management library to
$ORACLE_HOME/lib/libobk.so, or created a symbolic link to the library
calledlibobk.so.Forexample,youcancreateasymboliclinktothelibraryas
follows:
% ln -s /vendor/lib/oracle_lib.so $ORACLE_HOME/lib/libobk.so
Alternatively, you can simply change the name of the library tolibobk.so.
For example:
% mv /vendor/lib/oracle_lib.so $ORACLE_HOME/lib/libobk.so

If the instance to which one of the channels is connected does not have the database open, then the database must not be open by any instance. In other words, either all channels must be connected to open instances, or all channels must be connected to instances that are not open. For example, if the node1 instance has the database mounted while the node2 and node3 instances have the database open, then the backup fails.

Eliminating Migrated or Chained Rows in a Table
You can use the information in the CHAINED_ROWS table to reduce or eliminate migrated and chained rows in an existing table. Use the following procedure.

Use the ANALYZE statement to collect information about migrated and chained rows.
ANALYZE TABLE order_hist LIST CHAINED ROWS;


Query the output table:
SELECT *
FROM CHAINED_ROWS
WHERE TABLE_NAME = 'ORDER_HIST';

OWNER_NAME  TABLE_NAME  CLUST... HEAD_ROWID          TIMESTAMP
----------  ----------  -----... ------------------  ---------
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAA  04-MAR-96
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAB  04-MAR-96
SCOTT       ORDER_HIST       ... AAAAluAAHAAAAA1AAC  04-MAR-96


The output lists all rows that are either migrated or chained.

If the output table shows that you have many migrated or chained rows, then you can eliminate migrated rows by continuing through the following steps:
Create an intermediate table with the same columns as the existing table to hold the migrated and chained rows:
CREATE TABLE int_order_hist
   AS SELECT *
      FROM order_hist
      WHERE ROWID IN
         (SELECT HEAD_ROWID
            FROM CHAINED_ROWS
            WHERE TABLE_NAME = 'ORDER_HIST');


Delete the migrated and chained rows from the existing table:
DELETE FROM order_hist
   WHERE ROWID IN
      (SELECT HEAD_ROWID
         FROM CHAINED_ROWS
         WHERE TABLE_NAME = 'ORDER_HIST');


Insert the rows of the intermediate table into the existing table:
INSERT INTO order_hist
   SELECT *
   FROM int_order_hist;


Drop the intermediate table:
DROP TABLE int_order_history;


Delete the information collected in step 1 from the output table:
DELETE FROM CHAINED_ROWS
   WHERE TABLE_NAME = 'ORDER_HIST';


Use the ANALYZE statement again, and query the output table.
Any rows that appear in the output table are chained. You can eliminate chained rows only by increasing your data block size. It might not be possible to avoid chaining in all situations. Chaining is often unavoidable with tables that have a LONG column or long CHAR or VARCHAR2 columns.

CBO
Features that Require the CBO
The following features require use of the CBO:

Partitioned tables and indexes
Index-organized tables
Reverse key indexes
Function-based indexes
SAMPLE clauses in a SELECT statement
Parallel query and parallel DML
Star transformations and star joins
Extensible optimizer
Query rewrite with materialized views
Enterprise Manager progress meter
Hash joins
Bitmap indexes and bitmap join indexes
Index skip scans

ORA-ERROR
Ioctl ASYNC_CONFIG error, errno = 1
/wlrpt/app/oracle/product/920/rdbms/log/g18wlrpt_ora_28068.trc
Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.5.0 - Production
ORACLE_HOME = /wlrpt/app/oracle/product/920
System name: HP-UX
Node name: g18wlpd2
Release: B.11.23
Version: U
Machine: ia64
Instance name: g18wlrpt
Redo thread mounted by this instance: 0
Oracle process number: 0

FIX
Oracle(for HP only) always uses async I/O regardless of the value of init
(disk_asynch_io).
That's why this parameter filesystemio_options=none doesn't work.

Oracle always opens /dev/async successfully only if the /dev/async HP-UX
device driver is properly configured for read and write. This is irrespective
of whether the DISK_ASYNC_IO parm is set to TRUE.

So to unactivate ASYNCH_IO with Oracle , workaround could be:

chown bin:bin /dev/async
chmod 660 /dev/async

Order by 1

Install the DBMS_LOGMNR package. John installs the package by logging on to SQL*Plus as SYS and executing the $ORACLE_HOME/rdbms/admin/dbmslm.sql file.


Grant the role. John then grants the user who will do the mining—in this case, himself—the appropriate role to execute this package:


GRANT EXECUTE_CATALOG_ROLE TO JOHN;

 

Create the synonym. John creates a public synonym:


CREATE PUBLIC SYNONYM DBMS_LOGMNR FOR SYS.DBMS_LOGMNR;


These first three steps are required just once.


Specify the scope of the mining. Because the error may have happened just recently, it's possible that the change is still within the online redo log files. So, for the first pass, John decides to mine only the online redo log files. He identifies the files by running the following query:


SELECT distinct member LOGFILENAME FROM V$LOGFILE;

LOGFILENAME
________________________
/dev/vgredo01/rlog1a
/dev/vgredo01/rlog1b


These are the two redo log files for the database. John limits the scope of mining to only these files, by executing the following:


BEGIN
   DBMS_LOGMNR.ADD_LOGFILE 
      ('/dev/vgredo01/rlog1a');
   DBMS_LOGMNR.ADD_LOGFILE
      ('/dev/vgredo01/rlog1b');
END;

 

Start the LogMiner session and specify a dictionary. John executes the following SQL to start the LogMiner session:


BEGIN
   DBMS_LOGMNR.START_LOGMNR
   (options =>
dbms_logmnr.dict_from_online_catalog);
END;


Using the OPTIONS parameter, he also specifies that Oracle Database read the dictionary information to convert the object names from the online catalog while starting LogMiner.

As previously mentioned, redo log entries are not written in clear text. LogMiner provides human-readable reporting from the redo log files, but some reported values may not look like the original objects. For example, the owner, table, and column names are not recorded in the online redo log in the same format users input; they are instead converted to hexadecimal values. For instance, the ACCOUNTS table may be recorded as OBJ#45C1. To make the redo log data more readable, John can ask LogMiner to convert these values to more recognizable ones by translating them from a dictionary.


Check contents. Starting the LogMiner session populates a view named V$LOGMNR_CONTENTS, which John can then query to find out what happened to Ellen Smith's account. The query looks for the users and times of any updates against the ACCOUNTS table. The query against V$LOGMNR_CONTENTS and
