Character Report Generation Too Slow
Oct 12, 2010
I am using :
Database : Oracle 8i
Application Server: Oracle AS 9i
Developer Suite : Oracle 6i(forms & reports)
I have created some character reports in oracle reports 6i.. when reports used run from my ERP(oracle 6i oriented) ... report usually took time to create on server. Sometimes my ERP used to hang up due to busy reports generation. And then we have to kill some processes to finally create charater reports on emergency basis.What is the valid reason for slow generation of report(character file )?

I'm in 11203, and generation of ASH report is very slow.AWR and ADDM reports are generated quickly.To understand what happen, I check the wait event on the session that is executing ASH report, and I found that this session is waiting 99% with "controlfile sequential read". Is there any way to make the generation of ASH report quick ?Why the generation need to access to the controlfile?.

Is it possible to generate AWR report for the duration of 5 min? As we know that snapshots are generated for every 1 hour, which we specified in parameter.
By changing the parameter to 2 min, what could be the impact on database?

how do we know database character set is either single character set or multi character set?
While changing character-set from AL32UTF8 to WE8MSWIN1252 got "ORA-12712: new character set must be a superset of old character set".
Below are steps taken to resolve the issue -
ALTER DATABASE CHARACTER SET WE8MSWIN1252;
i got this error: ORA-12712: new character set must be a superset of old character set
below are the commands executed by me:
SQL> SHUTDOWN IMMEDIATE;
SQL> CONNECT SYS/password AS SYSDBA;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER DATABASE OPEN;
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE WE8MSWIN1252;
SQL> SHUTDOWN;
SQL> STARTUP;
SQL> QUIT;
And its working...
I have not done it in proper order. Neither have done ccsscan. Still, no user reported any issues. Do my changes truncated the data?

I'm trying to insert a character from the extended ascii character set. Specifically, there's a company that has an accented e (�) in the name. Right now, the company name doesn't have the e at all, accent or no accent. So I'm trying to do an update, something like
update table1 set company_name='blah�" where company='blah'
It runs, but doesn't do the update. Even when I try to forcefully do an insert (instead of an update) I get nowhere; the accented is simply dropped. So the basic question is, how do you insert extended ascii characters into oracle?

I am using C++ OCI LIB, to insert some report data from remote OCI client to oracle 11 server. This data is read by another process to create the report.The DB CHARSET is UTF-8. But the report tool expects the data to be ISO08859-1 encoded. So while inserting the data into the database i specify the following LANG and CHARSET for my table colulmn in client:
The TARGET DB CHARSET is UTF-8
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
size_t csid = 871; // UTF-8
OCIAtrSet((void *) bnd1p, (ub4) OCI_HTYPE_BIND,
*(void *)&csid*,
(ub4) 0,
(ub4)OCI_ATTR_CHARSET_ID, errhp);
This solution works for almost every case of ASCII and Extended ASCII Charest but we are facing issues if we have few specific characters to be inserted.f we are trying to insert single beta character [β] through client, the data goes empty to the column.
Beta Character details:
DEC OCT HEX BIN Symbol Description
223 337 DF 11011111 ß Latin small letter sharp s - ess-zed
DB Output after insert single β:
select rawtohex(NAME) from PERSONS where EID=333;
RAWTOHEX(NAME)
---------------------------
But if the string is *"ββ"* everything work fine:
DB Output for "ββ":
select rawtohex(NAME) from PERSONS where EID=333;
RAWTOHEX(NAME)
---------------------------
DFDF

Here is my situation.
1. I generate file_name through a function.
2. File name like File_DD_MM_YY_FLXXX.
3. Now this FLXXX is the filenumber. It will be 1 for the 1st run of the day and for each of the new run it will be +1. Again next day it will start from 1.
So right now I am using a sequence and resetting it at 12 AM to 0. Is it a good approach to solve the scenario?

11gr2, HP-UX, 64-bit. From last one week, we are seeing tremendous increase in archive-log growth. Its comes almost around 110GB per a day (db size=600g). I don't think its usual.Alertlog is clean and we don't see any alerts. Remedy app is built on this db and its creating tables on fly with LOB columns and indexes on them. As a first step. shall I disable logging for indexes on LOB columns ?

I have a base table by name EMP_MASTER.The Create Statement goes something like this....
CREATE TABLE EMP_MASTER(ST_CODE NUMBER,EMP_CODE NUMBER);We would like to insert records in such a way that there are 10 st_codes and for each st_code we need to insert 100 records.
FOR EX : for st_code 1 we need to have emp_code from 1 to 100 and then we need to insert st_code 2 and the emp_code must be from 101 to 200 and so on...... It must go in this way till we have st_code 10 and hope the emp_code will be in the range of 901 to 1000.
We need some thing similar to proc or PL/SQL block(declare begin..... end)

I have written a Java class which generate and place the XML file in a particular location. This the java class is loaded into Oracle using the loadjava command. When I call the sql java procedure java classn will be called and the XML file is generating.
But my problem is with xml header i.e in the header it is getting as
<?xml version = '1.0' encoding = 'UTF-8'?>
Where as I am generating the xml file from by just java call instead from Oracle the header is as follows
<?xml version="1.0" encoding="UTF-8" ?>
I am thinking that this could be reason with different jar using Oracle side.

I have a question on export dump file generation.
select sum(bytes)/(1024*1024*1024) "GB" from dba_segments where owner='JACK';
The above select query give the output of Schema size with 15 GB. When i perform the same schema export, the dump file size generating is 2 GB. What is the difference between the two scenarios as how come there could be a variation in file size?

Redo is getting generated very high. how to find out the reason ? database kept under 2 node cluster. chcked alert log trace and log writer trace files. pasted the content as below:
--alert log trace from node1 ( node2 also has same type of message ). Archive destination disk group - TXCOM_BACKUP_01 having enough space ( 80gb )
Mon Jan 7 00:49:10 2013
Thread 1 advanced to log sequence 448546 (LGWR switch)
Current log# 1 seq# 448546 mem# 0: +TXCOM_DATA_01/txcom/onlinelog/group_1.274.785770579

[code]...
In the alert log, I am able to see the archive destination disk group ( TXCOM_BACKUP_01 ) is getting DISMOUNTED and again getting MOUNTED during every archive file generation. .
Mon Jan 7 00:49:20 2013
SUCCESS: diskgroup TXCOM_BACKUP_01 was mounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was dismounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was mounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was dismounted
archive destination parameter in both nodes are not configured. it should read diskgroup name. ( +TXCOM_BACKUP_01 ) and corresponding size limit. Should i configure this ?
SQL> show parameter db_recovery
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string
db_recovery_file_dest_size big integer 0
[code]...
should i bring the database to mount stage and set log_archive_max_proesses to high count ? now value is 2 ( default )
