Server Administration :: Contention On Data Blocks?
Oct 22, 2010We are suffering from very bad application response for last few days, when i try to check and drill down, where the actual contention is? I came to know that there may be contention on data blocks, which may be a prime reason for degraded performance. Herewith i'm pasting my actual stats of gathered from v$waitstat. I gone through some of asktom docs and find that there may be a problem with freelist or segment space management. My data tablespace is segment space management = Manual.
My main question is
1) Should i need to increase freelist value (Right now my value is 1)
2) Or i have to move on segment space management = auto
SQL> select * from v$waitstat;

if i killed the SID - 1226, then those temp blocks ( 18176 blocks ) will be released and can other session use that space further ?
there is one more column - SEGBLK#
explain what is the exact meaning of this column ?
to reclaim the space, should i issue below command -

Jun 22, 2011trying to get oracle-xe-universal_10.2.0.1-1.0_i386.deb rolling on Debian/6.0.1a which coincidentally is on another server, not on my desktop, so I obviously can't reach the web frontend at 127.0.0.1:8080. And I couldn't trick it with a simple TCP proxy on the server:
nc -l -p 80 127.0.0.1 8080
and then on the client:

bailed out with an error
invalid connection to [192.168.0.252] from (UNKNOWN) [192.168.0.1] 35798
So, is there a way to change the listening IP address, or to allow IPs other than the local host to connect? I've tried some googling around,.

Fast Way To Retrieve All Data Blocks
Apr 19, 2012I am interested about the fast way to access all data in physical block. what is the quick way to bring data blocks using the rowid, I found this script but soon as I can have faster access:

WHERE ROWID between 'AAAUaOAAEAAHkJiAAA' and 'AAAUaOAAEAAHkJiAA8';
where 'AAAUaOAAEAAHkJiAAA' is the last element in the block and 'AAAUaOAAEAAHkJiAA8' is the first one
my question is can retrieve all the data in one block more quick than this query.

View 6 Replies View RelatedForms :: Entering Multiple Data In A Form Containing 4 Blocks
Jul 18, 2011I have 4 blocks in my form which is basically used for travel booking for the employees in a company within India
1) Header block :- contains info abt the person who is booking the tickets for number of employees. Here i have given booking no a primary key.
2) Employee Detail :- Here the basic info of an employee is entered. Here i have taken booking number as a foreign key and then given emp_cd & booking number as a composite primary key.
3) Travel Detail :- Here the travel detail of individual employee will be entered wherein a unique trv_no will b generated 4 every single travel. Again i have taken foreign key as bkng_no frm 1st blck and emp_cd frm 2nd blck and tkn a composite primary key which comprises of bk_no,emp_cd and trv_no. this is used to maintain the uniqueness for single travel.
4) Vehicle Hotel Details :- This block is placed on different canvas for same form.It is meant for Other details in which details regarding hotel,vehicle etc booking aftr reaching the destination is entered. In this block thrs no primary key, but i hv taken the composite primary key of 3rd block as a foreign key since thr will be multiple entries for this one entire travel.
At every level there will be multiple entries for each corresponding entered record. I am able to enter one single record properly i.e. for 1 emp i am able to enter multiple travel details and his other requirements but asi try to enter more then one employee info, his travel details, other requirements i face an error stating foreign key constraint violated.Parent key not found for 3 rd level block.
How can i get the desired o/p wherein all the multiple records for every single subsequent record are stored correctly taking all the constraints in to consideration.

Forms :: Removing / Changing Form On Server Does Not Affect Anything?
Sep 15, 2011Actually, i found that some forms if they are changed (like some buttons/text fields/code added to them) and this change can be saved and there is no errors in compilation. but when this form is run from the application, the change is not visible.
Even if the form with the image is removed from the directory, it still runs from the application link. Is there some memory issue or anything else.

Server Administration :: Flashback Data Archive
Aug 23, 2011I need store history for two tables in my system. I thought that Flashback Data Archive will be the best option. There is also another ways to do this but don't focus on this. I need to to this by FDA (Flashback Data Archive);
So my prerequisite was to create tablespace and flash back archive, and alter table to be archived.
create tablespace audit_archive datafile 'd:oradata etaaudit_archive.ora' size 100M;
create flashback archive audit_flash_archive
tablespace audit_archive quota 10G retention 10 year;
alter table teta_admin.t_prac flashback archive audit_flash_archive;
and everything works fine but on sys user.
i can query this table using "as of timestamp" clause
select prac_id, imie, imie_2, nazwisko, nr_ew from teta_admin.t_prac as of timestamp to_timestamp('2011-08-23 08:20:00','yyyy-mm-dd hh24:mi:ss')
but final construction of idea was to create additional user (interface), grant select on teta_admin.t_prac object and query archive data from interface user. and this is point of my failure. this don't work on new user.
interface user have such sys privs:
SQL> SELECT * FROM dba_sys_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
INTERFACE CREATE SESSION NO
and table privs:
SQL> SELECT * FROM dba_tab_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE
------------------------------ ------------------------------ ------------------------------ ------------------------------ --------------------
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN INSERT
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN DELETE
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN ALTER
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN FLASHBACK
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN SELECT
what i need to do in order to query this flashback table from interface user. when i try to do this from this user oracle says ORA-00942.
