Oracle 11g listener issue

Hello,
I have installed oracle 11g on windows 7. Installation and database creation was successfull but after creating database listener should automatically up and start
but i am not able to listener in the services window and not able to conntest database using connect string.
I tried to create new listener using netca but it is hanging ..
I have downloaded this software from oracle website.
any idea where can i check to resolve this issue.

Hi,
I had the same problem as the OP, and I followed these instructions to try and see which error was raised by the listener when it started.
Weird thing is, after deleting the listener.ora file and restarting the listener with the "lsnrctl start" command, it worked !
The only additional thing I did is (as written in some obscure Oracle documentation) create a loopback network adapter (because my PC is DHCP-based).
Now I have rebooted my PC, and it still works. Go figure...
I hate Oracle. They shouldn't have been authorized to buy back Sun. My prediction is that Java is going the same way as their DB : it's gonna be a mess... :(Just because you can't make things work and find the documentation obscure doesn't mean things don't work. Its not Access with point-click you see!

Oracle 11g - Date Issue?

Oracle 11g - Date Issue?
=====================
I hope this is the right forum for this issue, if not let me, where to go.
We are using Oracle 11g (11.2.0.1.0) on (Platform : solaris[tm] oe (64-bit)), Sql Developer 3.0.04.
Our NLS_DATE_FORMAT = 'DD-MON-RR'
Using 'RR' in the format forces two-digit years less than or equal to 49 to be interpreted as years in the 21st century (2000–2049), and years 50 and over, as years in the 20th century (1950–1999). Setting the RR format as the default for all two-digit year entries allows you to become year-2000 compliant. For example:
We have a date '01-JUN-31' in our source system. It treat this date as 01-JUN-2031' instead of '01-JUN-1931'. One century forward.
Do we able to resolve using NLS_DATE_FORMAT change?
How do we resolve this issue?
Thanks in helping.

Our source is Oracle data base, where S_date is defined as DATE. Why did you say STRING , when it defined as DATE data type?I doubt you source is an Oracle database. You may have it stored in an Oracle database, but it cam form somewhere else, and was very likely inserted into the table as a string, wherever it came from. Given a string that resembles a date, Oracle will try to convert it to a date using the nls_date_format parameter for the session (which can either be set in the session or inherited form the database). Perhaps this will help explain:
SQL> create table t (conv_type varchar2(10), dt date);
Table created.
SQL> alter session set nls_date_format = 'dd-mon-rr';
Session altered.
SQL> insert into t values ('Implicit', '01-jun-31');
1 row created.
SQL> insert into t values ('Explicit', to_date('01-jun-1931', 'dd-mon-yyyy'));
1 row created.
SQL> commit;
Commit complete.
SQL> select conv_type, to_char(dt, 'dd-mon-yyyy') dt
2 from t;
CONV_TYPE DT
Implicit 01-jun-2031
Explicit 01-jun-1931So, unless you are really inserting dates, not strings that look like dates, you are going to have problems.

Oracle 11G Configuration Issue

Hi All,
I am in the process of installing Oracle Forms and Reports 11g[11.1.2].
I have installed Oracle 11g, getting a issue while configuring it.
INST – 07249 :An Unexpected error occurred during the validation of Middleware home location
INST-07286: Specified Oracle Middleware home locationdoes not have version 10.3.5 of weblogic server.If the version is incorrect then configuring with the weblogic server will fail
WLS 10.3.5 have been installed, and I can access the Admin console.
I did checked for the WLS version in its registry file created on WLS installation to confirm its version number.
I have used the same middle ware home location which I used to install the WLS.
Please can you get me some information to overcome this issue?

This is well explained from user's guide:
Stopping Node Manager Before Installing Oracle Forms and Reports (Windows Only)
If you are installing Oracle Forms and Reports on a Microsoft Windows operating system, you must make sure that the Node Manager utility that was installed with Oracle WebLogic Server is stopped before you begin the installation:
1.     Verify the Oracle WebLogic Server Node Manager utility is stopped. If it is running, kill the process.
2.     Determine if the nodemanager.properties file is present in the WebLogic_Home\common\nodemanager directory.
*1.     If the nodemanager.properties file is not present, continue installing Oracle Forms and Reports.*
*2.     If the nodemanager.properties file does exist, open it and verify that the ListenPort parameter is included and that it is set. If the ListenPort parameter is not included or set, edit the nodemanager.properties file so that it is similar to the*
following, where NODE_MANAGER_LISTEN_PORT represents the port the Node Manager listens on, such as 5556:
*3.     ListenPort=NODE_MANAGER_LISTEN_PORT*

Oracle 11g Listener Supports No services

I have installed Oracle 11g in Linux (Centos). i created a starter database using dbca. I also created a listener.ora using netca.
I have observed that that the listener.ora was only generated like this after running netca:
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST =proky.warnerbro.com)(PORT = 1521))
)Now when i start this listener, I get a message: "The listener supports no services".
I have read on some forums that something like this should be included:
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = $$###$)
      (ORACLE_HOME =$ORACLE_HOME)
      (PROGRAM = extproc)
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = $ORACLE_HOME)
      (SID_NAME = orcl)
)So, my question is, do dba's edit this manually or there should be a tool or wizard that would generate this text in listener.ora.
thanks in advance,
Anton

Thanks guys.
Another question though.
How can I edit the listener that is used by emctl (database control)? Cause I have edited my listener.ora. I have removed an entry originally listened to by database control. For Example, originally there was a listener called listener3 which was used by emctl. Now I run netca and remove "listener3" and add one listener "listener". If i check listener.ora at ORACLE_HOME/network/admin, the file now has an entry listener and no more listener3.
However when I start emctl, it says there that is still uses the "listener3" listener
So even if i issued a "alter system register" at sqlplus, I still can't find my database on emctl.

Oracle 11g : Sequence Issues after impdp

Hi All,
We are migrating from Oracle 10g to Oracle 11g. As part of this, we take a expdp from 10g and successfully did an import using impdp on to Oracle 11g database.
But the problem is, there were few Primary key violations which occurred and all of them relate to sequences.
The Maximum data in the tables and the last number in the sequences differed which caused the issue.
Upon investigation and browsing the Web, http://www.nerdliness.com/article/2009/03/18/my-oracle-sequencedatapump-shenanigans ; I understood it could be because of the export taken while the application is online and writing to the database.
I reset all the failing sequences manually and it is fine now.
My questions now are
*1) Can we ascertain that the export taken when the source database is offline would eliminate the sequences issue.*
2) As this is being done in Production, I would like to make few checks to ensure that the sequences are properly imported. ---
Again reading few websites and oracle Forums, i found the below sql's..
select table_name, column_name, utl_raw.cast_to_number(high_value) as highval
from dba_Tab_columns
where owner = 'PRODUCTION_OWNER'
AND DATA_TYPE= 'NUMBER'
AND (OWNER, TABLE_NAME, COLUMN_NAME) IN
(SELECT CC.OWNER, CC.TABLE_NAME, CC.COLUMN_NAME
FROM DBA_CONS_COLUMNS CC
JOIN DBA_CONSTRAINTS C
ON CC.OWNER=C.OWNER
AND CC.CONSTRAINT_NAME=C.CONSTRAINT_NAME
WHERE C.CONSTRAINT_TYPE ='P'
ORDER BY 3;
SELECT SEQUENCE_NAME, MIN_VALUE, MAX_VALUE, LAST_NUMBER
FROM DBA_SEQUENCES
WHERE SEQUENCE_OWNER = 'PRODUCTION_OWNER'
ORDER BY LAST_NUMBER
If I relate the last_number with the highval and if they are same, does that mean the sequences are imported properly.
Note: We have sequence caching done and we are on RAC.

it could be because of the export taken while the application is online and writing to the database.I don't know what's your database's size , and what's acceptable downtime for you, but I could never propose such a migration tecnique to any of my customers, due to excessive downtime when databases are quite large.
It's quite obvious that you get such errors when the export is done while people are working, unless you use FLASHBACK_SCN or FLASHBACK_TIME parameter while exporting. But in this case, assuming you don't get errors (e.g. ORA-01555), you'll probably lose a lot ot transactions.
Assuming your 10g database is running in archivelog mode (which should be the default in production DBs) did you think of using RMAN to do the migration ?

Oracle 11g decode issue with null

Hi,
we want to migrate from Oracle 10g to Oracle 11g and have an issue with decode.
The database has the following character set settings:
NLS_CHARACTERSET = AL32UTF8 in Oracle 11g and UTF8 in Oracle 10g
NLS_NCHAR_CHARACTERSET = AL16UTF16
If I try a select with decode which has null as first result argument I will get a wrong value.
select decode(id, null, null, name) from tab1;
("name" is a NVARCHAR2 field. Table tab1 has only one entry and "id" is not null.)
This select returns a value with characters which are splitted by 0 bytes.
In Oracle 10g the value without 0 bytes is delivered.
If I suround the decode with dump I get following results:
select dump(decode(id, null, null, name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=US7ASCII: 0,4d,0,61,0,72,0,74,0,69,0,6e
NLS_LANG has no effect on the character set of 'null' in Oracle 11g.
Non null literals work:
select dump(decode(id, null, 'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
select dump(decode(id, null, N'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Here the scripts for creating the table and the entry:
create table tab1 (
id NUMBER(3),
name NVARCHAR2(10)
insert into tab1 (id, name) values (1, N'Martin');
commit;
Is it possible to change the character set?
Could you please help me?
Regards
Martin

This doesn't have the problem.looks this doesn't solve the problem (of returning a value with characters which are splitted by 0 bytes):

I have the same issue, but my client (export) is 11.1.0.7.0 and my database is 11.1.0.6.0. I beleaved that the same versions (11) have to work toghether. But they do not.
Does it mean that I have to reinstall my client to have en export that works?

Oracle 11g Performance Issue

We have Oracle 11g (11.1.0.6) on HP-UX environment with CC&B application. It was working fine and after we upgrade the database to 11.1.0.7 last week, since then the database performance is really slow. After we upgrade the database we notice that xdb component became invalid.
We are not sure how to investigate this issue, any help would be appreciated.

Oracle 11g upgrade issues

Hello :
We recently migrated our database from 9.2.07 (RBO) to 11.2.0.1 (CBO) ( Solaris 10 Sparc 64 bit ). Ever since the migration happened we are experiencing the following issues:
1. Execution plans are very costly. ( Please note that we moved from RBO to CBO )
2. High Gets / Reads
3. High CPU Utilization
4. High waits on 'DB FILE SEQUENTIAL READ'
5. This situation is vitually killing all our applications performance.
I know that oracle 11g explicitly does not support RULE based optimizer , but is there any parameters that can force it go the RBO way.
I would really appreciate your help.
Regards,
BMP

Oracle 11g performance issue ( BITMAP CONVERSION TO ROWIDS)

I have two instance of oracle 11g.
in both instance i fired same query.
one instance returns the result in 1sec but other instance returns the result in 10 sec
following is explain plan for bot instance

in both explain plan only difference is
9 BITMAP CONVERSION TO ROWIDS
8 BITMAP AND
5 BITMAP CONVERSION FROM ROWIDS
but is bitmap degrading performance lot?
or suggest me what other parameter i can see so 2nd instance gives me better performace.

I see more differences.
In plan 1:
* 16 INDEX RANGE SCAN idx_bf_creation_date 76 1 (0) 00:00:01
in Plan 2:
1 INDEX FULL SCAN (MIN/MAX) INDEX REPORTSDB.idx_bf_creation_date Cost: 3 Bytes: 8 Cardinality: 1
So this is not about "bitmap" good/bad, it about the access strategy which changed due to differences in data statistics etc. To analyze more, I'd help a LOT if those plans would be formated in a good and same way, use around it to do so.

Oracle 11g performace issue

hi all,
am using oracle 11g enterprise edition., i didn't ran any query but in ADDR report it was running some sytem based query(SYS,DBSNMP,SYSMAN etc)
but in previous 10g it was working fine.. can anyone tell me how to stop those query..
this is the query was running most frequently :
select end_time, wait_class#, (time_waited_fg)/(intsize_csec/100), (time_waited)/(intsize_csec/100), 0
from v$waitclassmetric union all
select fg.end_time, -1, fg.value, bg.value, dbtime.value
from v$sysmetric fg, v$sysmetric bg, v$sysmetric dbtime
where bg.metric_name = 'Background CPU Usage Per Sec' and bg.group_id = 2 and fg.metric_name = 'CPU Usage Per Sec' and fg.group_id = 2 and dbtime.metric_name = 'Average Active Sessions' and dbtime.group_id = 2 and bg.end_time = fg.end_time and fg.end_time = dbtime.end_time order by end_time,wait_class#
UPDATE MGMT_JOB_EXECUTION SET STEP_STATUS=:B2 WHERE STEP_ID=:B1

UPDATE MGMT_JOB_EXECUTION SET STEP_STATUS=:B2 WHERE STEP_ID=:B1Why are you so concerned about background queries? Do you really think these queries uses high resource and have high elapsed time then you custom queries? The god way to diagnose a performance problem is to identify most resource intensive/time consuming program/module/code rather then running after background queries. Yes sometimes background queries too run slowly in rear cases and then you need to run dbms_stats.gather_dictionary_stats or dbms_stats.gather_fixed_objects_stats (https://blogs.oracle.com/optimizer/entry/fixed_objects_statistics_and_why)

Oracle 11g install issues on Windows 7

I have had some problems installing Oracle on Windows 7 in that it seemed to crash while checking prerequisites. After several attempts it for some reason continued the installation. I had accepted the default settings and was installing from a USB drive to the same drive. The install did have a few error messages along the way such as "file not found. F:\app\ben\product\11.2.0\dbhome_2\oc4j\j2ee\oc4j_applications\applications\em.ear" and ""file not found. F:\app\ben\product\11.2.0\dbhome_2\ctx\admin\dr0ulib.sql.sbs". Also, towards the end it gave a message "Template General_Purpose.dbc does not exist. Please specify an existing template for database creation. <OK>". Despite these errors it seemed to successfully install. On the other hand I cannot log in to it as I attempt to try to set up some kind of basic database for myself. I go to the BIN directory and run sqlplus with "system" as the username and the password I had specified, but get the error "ORA-12560: TNS:protocol adapter error". Googling around a bit I tried to see if Oracle Services was running, but only saw OracleMTSRecoveryService and OracleRemExecService (and could not work out how to get any service running beyond what was listed there). I set up the path ORACLE_HOME to the BIN directory but there was not change in the situation. I just need a to set up a basic database on my PC so I can mess around with it. How can I get this going?
Thanks,
Ben

Oracle 11G Searching Issue : Statistics Corruption

Hi,
I guess their is some issue with oracle statistics for Text Indexing. Some times i got an issue regarding Text index searching, query throwing wrong results. and when i fire this command :-
execute immediate 'analyze table ' ||' '||tablename ||' '||'delete statistics';
for deleting statistics. the query returns the correct results.
I guess this is the problem of "stale statistics" , Is their any way to sort out this problem ?
Any help please ?

Hi,
I have Oracle Version - 11g Release 1 (11.1.0.6)
Yes you are absolutely correct, Even i am not getting that why oracle is behaving like this. But i have shown this behaviour many times ( once in 2-3 months approximately )
I know that we can provide hint in the queries but i cant give hints.
Any Help please ?
