Posted on by Osama Mustafa in Application

Logging into “SBA_81_DSN” as “SADMIN” …
ODBC error 81 in SQLConnect:
523 72
(native error 0).
Unable to login using specified ODBC parameters.

The above error appear when you are trying to run the below command:

odbcsql /s SIEBEL8_DSN /u sadmin /p sadmin

Solutions :

Make sure the you set TNS_ADMIN in .profile or .bash_profile , TNS_ADMIN Should be Directed to Client32 bit , Copy tnsnames.ora from Database home to Client32

it will be like the following :

export TNS_ADMIN=/u01/app/oracle/instanctclient32/

Queryable Patch Inventory New Features 12c

Posted on by Osama Mustafa in Database
Again !!! Oracle 12c Under test , every time i tested it i discover new features, while i am testing today i found new folder under $ORACLE_HOME called QOPatch , for the first time when i opened this folder i only found two files,

Check the https://support.oracle.com note :

Oracle Database 12.1 : FAQ on Queryable Patch Inventory [ID 1530108.1] 

from the name you can see it’s retrieve  information  using query, and to use query you have to get access to SQL Plus, this features  allow you access to the OPatch information from within the database.  This Package called  DBMS_QOPATCH

Some of Attribute to use with this package :

  • GET_OPATCH_INSTALL_INFO
  • SET_CURRENT_OPINST
  • GET_OPATCH_LIST
  • IS_PATCH_INSTALLED
  • GET_OPATCH_DATA
  • GET_OPATCH_BUGS
  • GET_OPATCH_FILES
  • GET_OPATCH_COUNT
  • GET_OPATCH_PREQS
  • GET_OPATCH_OLAYS
  • PATCH_CONFLICT_DETECTION
  • GET_PENDING_ACTIVITY
  • GET_OPATCH_XSLT
  • GET_OPATCH_LSINVENTORY
  • GET_SQLPATCH_STATUS

Since this function used to get Opatch information within database then you have to access to SQL Plus 
Check the below examples :

SQL> select dbms_qopatch.get_opatch_lsinventory() from dual;

DBMS_QOPATCH.GET_OPATCH_LSINVENTORY()
——————————————————————————–

Another Examples :

SQL> select dbms_qopatch.GET_PENDING_ACTIVITY() from dual;
DBMS_QOPATCH.GET_PENDING_ACTIVITY()
——————————————————————————–

My Database still fresh and not patch yet So you will not find that much of information 
Thank you

ORA-00607/ORA-00600

Posted on by Osama Mustafa in Database

ORA-00600: internal error code, arguments: [4193], [4271], [4056], [], [], [], [], []

As you see the above error ORA-00600 usually Indicate for Bug, A mismatch has been detected between Redo records and Rollback (Undo)  records. and to solve this issue you need to do the below :

SQL> show parameter undo
NAME                                 TYPE        VALUE
———————————— ———– ——————————
undo_management                      string      AUTO
undo_retention                       integer     900
undo_tablespace                      string      UNDOTBS

SQL> alter system set undo_management=’MANUAL’ scope=spfile;

SQL > Shutdown immediate ;
SQL > Startup ; 

SQL > create undo tablespace NEW_UNDOTBS datafile ‘/u01/app/oracle/oradata/SID/NEW_UNDOTBS01.DBF’ size 1G ;

SQL> alter system set undo_tablespace=’NEW_UNDOTBS’ scope=spfile;

System altered.

SQL> alter system set undo_management=’AUTO’ scope=spfile;

System altered.

 After Shutdown The new Effect Should be Taken And If you want to Drop Old Undo you can do This another option you can use is Take if Offline. Sometimes when you want to drop Old Undo you receive new error : 

SQL> drop tablespace UNDOTBS01 including contents;
ORA-01548: active rollback segment ‘_SYSSMU1_1255349037$’ found, terminate dropping tablespace

So What Can i do Take Offline Or The Below Option :

SQL> select * from v$rollname ;

USN NAME
———- —————–
0   SYSTEM
1  _SYSSMU1$
2 _SYSSMU2$
3 _SYSSMU3$
4 _SYSSMU4$
5 _SYSSMU5$
6 _SYSSMU6$

 SQL > Create Pfile=’/u01/New.init’ from spfile
 File Created

SQL > Shutdown immediate ;

Edit pfile 

*.undo_management=’MANUAL’
*.undo_retention=1800
*.undo_tablespace=’NEW_UNDOTBS’
*._offline_rollback_segments= (_SYSSMU1$,_SYSSMU2$,_SYSSMU3$,_SYSSMU4$,_SYSSMU5$,_SYSSMU6$ )

  • Startup database from new pfile without create spfile ;
  • try to Drop Tablespace Now, this way should work.
  • After drop Undo Tablespace, Remove _offline Parameter and undo_management to AUTO 

Thank you

Find Resote Point Rman

Posted on by Osama Mustafa in Database
Some Times you need to Restore your Database To Earlier time , and before doing that you have to check weather database have valid to do that or not

Simple Query :

SQL>  select resetlogs_change#,to_char(resetlogs_time,
 'DD-MON-YYYY HH24:MI:SS') Last_resetlog_time from v$database_incarnation;
 
RESETLOGS_CHANGE# LAST_RESETLOG_TIME
----------------- --------------------
                1 11-SEP-2008 22:57:51
           88033 23-MAY-2011 10:12:42
 
Or Sometimes you could Use v$restore_point , Such as
 
SELECT scn, time, database_incarnation#, guarantee_flashback_database from
v$restore_point;
