ORA-01110 When trying to Open Database

Posted on by Osama Mustafa in Database
ALTER DATABASE OPEN
*
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 5: ‘ /u01/test/users02.dbf’

This Error Maybe Appear On Different Database Files Because DBF Not Exists .

Solution
1-Restore From Rman if its Not Found .

Or

SQL> select file#,name, status from v$datafile where file#=5;
FILE# NAME STATUS
———- ————————————————- ———–
5 /u01/test/users02.dbf ONLINE

SQL>
SQL> alter database datafile ‘/u01/test/users02.dbf’ offline drop;
Database altered.

SQL> alter database open;
Database altered.
SQL>

FRM-92102 : A network error has occured

Posted on by Osama Mustafa in Database
FRM-92102 is Gerneric Error maybe occur for more than one reasons :

1-Network 
2-Proxy
3-http
4-Session Time 


But today i will discuss the problem On oracle Application server 10g .
Description for the problem like the following when you try to connect on your deploy application On OAS 10g it’s gives the above error from 1-5 minutes.

I will give you more than one solution maybe it will be related to the above problem and you try them separately to see which one will be valid for you : 

1-Netowrk Parameters :

You will find it $ORACLE_HOME/forms/server/default.env
Just increase the value .

2-do the following change in opmn.xml (under $ORACLE_HOME/opmn/conf/):

 

3-SET Inbound_connection_timeout In sqlnet.ora to ZERO .

Sqlnet.Inbound_connection_timeout = 0

Note : if your can’t find this parameter in the SQLNET.ORA you cant add it .

5- Change the following $ORACLE_HOME/opmn/conf/opmn.xml


Hope this will work 

Thank you

Want Solution Do the following : 
 
you can add the new TNS connect string (UR = A) to the tnsnames entry.
 
ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ORCL)
      (UR = A)
    )
  ) 
 
if the above Solution not working Make sure your listener look like :
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\oraserver\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\oraserver\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC =
      (SID_NAME=orcl)
      (ORACLE_HOME=D:\app\oraserver\product\11.2.0\dbhome_1)
    )
  )
 
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )
