11g File Watcher

http://docs.oracle.com/cd/E11882_01/server.112/e25494/scheduse005.htm
http://www.oracle-base.com/articles/11g/scheduler-enhancements-11gr2.php
http://awads.net/wp/2011/03/29/did-you-know-about-file-watchers/

A file watcher is a new scheduler object that enables a new type of even-based job that is triggered by the arrival of a file in a specified location. File watchers can be defined to monitor locations on the local server and remote servers, provided they have an agent installed on them.

We want oracle to import all the objects belonging to HR schema automatically whenever a .dmp file arrives in a specified folder on a system.
To implement it we will use filewatcher which is a new scheduler object in oracle 11g. It enables a new type of event-based job that is triggered by the arrival of a file in a specified location. File watchers can be defined to monitor locations on the local server and remote servers, provided they have an agent installed on them.

I am loading a file to a oracle table every day between 8 a.m and 9 a.m. The file may come at any time between 8 a.m to 9 a.m.
As of now, we are manually checking the file availability and then loading the file into oracle table.
My client is asking us to automate this process. My team is wondering if there is any way we can schedule based on file arrival in a specified location.

SELECT file_watcher_name, destination, directory_path, file_name, credential_name FROM user_scheduler_file_watchers;

11g Migration using RMAN

The steps for 10g database:

1- Run the utlu112i.sql Pre-upgrade script. You can find this script under @$ORACLE_HOME/rdbms/admin/. It must be copied from the 11g database software.

SQL> @$ORACLE_HOME/rdbms/admin/utlu112i.sql

This script adds a column named tz_version to table named registry$database. Pre-upgrade script updates this column with the value of the following query.

SQL> select version from v$timezone_file;

So it performs following operation.

SQL> ALTER TABLE registry$database ADD (tz_version NUMBER);
SQL> UPDATE registry$database set tz_version =4;

SQL> ALTER PACKAGE “SYS”.”DBMS_REGISTRY” COMPILE BODY;
SQL> ALTER VIEW “SYS”.”DBA_REGISTRY_DATABASE” COMPILE;

2- Connect to 10g database and take RMAN full backup.

#rman target /
RMAN> backup as backupset database;

3- Copy 10g database backup files and archive files to 11g database server.

The steps for 11g database:

1- Create temporary pfile in $ORACLE_HOME/dbs

*.audit_file_dest=’/oracle/admin/TALIPDB/adump’
*.compatible=’11.2.0.0.0′
*.control_files=’+DATA/talipdb/controlfile/current.257.787742981′,’+DATA/talipdb/controlfile/current.258.787742983′
*.db_block_size=8192
*.db_create_file_dest=’+DATA’
*.db_create_online_log_dest_1=’+RECO’
*.db_domain=”
*.db_name=’TALIPDB’
*.diagnostic_dest=’/oracle’
*.job_queue_processes=0
*.open_cursors=300
*.pga_aggregate_target=1G
*.processes=150
*.remote_login_passwordfile=’EXCLUSIVE’
*.sga_target=2G
*.undo_tablespace=’UNDOTBS1′

2- Open the database in NOMOUNT state.

# rman target /

RMAN> startup nomount;

3- Restore controlfile from backup.

RMAN> restore controlfile from ‘/oracle/ora11g/talipdb/backup/c-784951186-20120620-02′;

4- Open the database in MOUNT state.

RMAN> alter database mount;

5- Catalog RMAN backup files and archive log files.

RMAN> catalog start with ‘/oracle/ora11g/talipdb/backup’;
RMAN> catalog start with ‘/oracle/ora11g/talipdb/archive’;

6- Restore 10g database backup to +DATA diskgroup and perform incomplete recovery.

RMAN> run
{
allocate channel c1 device type disk;
SET NEWNAME FOR DATAFILE 1 TO ‘+DATA’;
SET NEWNAME FOR DATAFILE 2 TO ‘+DATA’;
SET NEWNAME FOR DATAFILE 3 TO ‘+DATA’;
SET NEWNAME FOR DATAFILE 4 TO ‘+DATA’;
restore database until sequence 4;
switch datafile all;
recover database until sequence 4;
}

7- Open the database with RESETLOGS UPGRADE.

# sqlplus / as sysdba
SQL> alter database open resetlogs upgrade;

8- Run the upgrade script.

SQL> SPOOL upgrade.log
SQL> @$ORACLE_HOME/rdbms/admin/catupgrd.sql
SQL> SPOOL off

9- If our 10g and 11g database os platforms are different then you must run utlmmig.sql script.

————–Changing 32 bit to 64 bit————–
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP UPGRADE
SQL> SPOOL migrate.log
SQL> @$ORACLE_HOME/rdbms/admin/utlmmig.sql
SQL> SPOOL off
——————————————-

10- Now, you can open the database.

SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP

11- Run the Post-Upgrade script to check problems.

SQL> @$ORACLE_HOME/rdbms/admin/utlu112s.sql

12- Compile invalid objects.

SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql

13- Drop the temporary file and create new one in +DATA diskgroup.

SQL> alter tablespace temp drop tempfile ‘/data_TALIPDB/temp01.dbf’;
SQL> alter tablespace temp add tempfile ‘+DATA’ size 1024M;

Listener ORA-00119 ORA-00132

Issues with setting Local Listener ORA-00119 ORA-00132

Today I was caught up in a issue with TNS while trying to setup SOA setup with OEM

Windows64bit machine

Database 11gr2

As per requirement we wanted to run the listener not on default port (1521 ) but some other port. Now as per Documentation if i want my non default port listener to register with pmon i need to set local_listener

“If you want PMON to register with a local listener that does not use TCP/IP, port 1521, then configure the LOCAL_LISTENER parameter in the initialization parameter file to locate the local listener.”

I though it will be a straight forward process just go ahead and run the alter system set local_listener=listener2 scope=both; but to surprise it didnt work as expected it returned an error

ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER2' … so a straightforward process didnt work as expected.

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=TAQVIA-IN.xx.xxx.com)(PORT=1522))))' sid='orcl64' scope=both

----------------------------------Startup fails with oracle error ORA-00119, ORA-00132-----------------------------------------------
Error Description:
---------------------------
Database Startup fails with oracle error ORA-00119, ORA-00132
SQL> startup mount
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_DBASE'

Cause of The problem:
-------------------------
If the tnsnames.ora entry was used for the value of the LOCAL_LISTENER and the LOCAL_LISTENER entry inside tnsnames.ora is changed or tnsnames.ora file is moved and hence the tns alias to which the LOCAL_LISTENER parameter points is no longer valid. So, the entry inside spfile or pfile to be unresolvable, and the database will not start.

PMON must be able to resolve whatever value the LOCAL_LISTENER or REMOTE_LISTENER parameter is set to. Here LISTENER_DBASE is the name of the local listener.

Remember the LISTENER_DBASE is NOT the listener name reflected in the listener.ora file but rather it is an alias stored in the tnsnames.ora file.

Solution of The problem
-----------------------------
A)Correct the tnsnames.ora

i)Determine if the tns alias is good by using tnsping.

SQL> !tnsping LISTENER_DBASE
TNS Ping Utility for Solaris: Version 10.2.0.1.0 - Production on 15-MAY-2008 11:57:06
Copyright (c) 1997, 2005, Oracle. All rights reserved.

Used parameter files:
/oracle/app/oracle/product/10.2.0/db_1/network/admin/sqlnet.ora
TNS-03505: Failed to resolve name

So it could not find the name inside tnsnames.ora.
ii)
Add the LISTENER_DBASE entry in the tnsnames.ora file.

SQL> !vi /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
LISTENER_DBASE=(DESCRIPTION=(address=(protocol=tcp)(host=neptune)(port=1522)) (sid='dbase')

and run tnsping utility,

SQL> !tnsping LISTENER_DBASE

Copyright (c) 1997, 2005, Oracle. All rights reserved.
Used parameter files:
/oracle/app/oracle/product/10.2.0/db_1/network/admin/sqlnet.ora

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION=(address=(protocol=tcp)(host=neptune)(port=1522)) (sid='dbase')
TNS-12533: TNS:illegal ADDRESS parameters

So there is syntax error in the LISTENER_DBASE alias. Correct it as here add parenthesis.

SQL> !vi /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
LISTENER_DBASE=(DESCRIPTION=(address=(protocol=tcp)(host=neptune)(port=1522)) (sid='dbase')))

iii)After correction run tnsping and start the database.

B)An alternative solution is to remove the LOCAL_LISTENER entry from the listener.ora file.
1)Create spfile from pfile if you don't have pfile upadted.
SQL>CREATE PFILE FROM SPFILE;

2)Open the pfile and remove the LOCAL_LISTENER entry.

$vi /oracle/app/oracle/product/10.2.0/db_1/dbs/initdbase.ora

3)Create spfile from pfile.
SQL>CREATE PFILE FROM SPFILE;

4)Start the database.

Recommendation:
------------------
Though you can set the value of LOCAL_LISTENER (or REMOTE_LISTENER parameter if used) as alias in tnsnames.ora like in this example but it is not recommended setting. Instead use a full address descriptor inside pfile or set dynamically inside spfile.

In order to set dynamically inside spfile and in memory log in with dba privileges and issue:

ALTER SYSTEM set LOCAL_LISTENER="(address=(protocol=tcp)(host=yourhost)(port=yourport))" scope=both sid='instancename';

In my system,

SQL> ALTER SYSTEM set LOCAL_LISTENER="(address=(protocol=tcp)(host=neptune)(port=1522))" scope=both sid='dbase';

SQL> show parameter local

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (address=(protocol=tcp)(host=neptune)(port=1522))

ora 12560 tns protocol adapter error database DBCA fails

ora 12560 tns protocol adapter error database DBCA fails

-------------------Most common reasons for ORA-12560 in Windows are----------------------------

- firewall (port 1521)
- DHCP and not using loopback adapter
- antivirus
-Windows Domain Control should not be installed(Oracle recommends to NOT install it on a domain controller.)
-There was no ORA_DBA group and no ORADBA user on the server

while creating database in oracle 11.2.0.1 using DBCA i am getting following error.

ora 12560 tns protocol adapter error

i am using administrator userid . any soultion for this

1)
It seems you use windows OS so go %ORACLE_HOME%\network\admin directory and edit sqlnet.ora then change/add context below text
SQLNET.AUTHENTICATION_SERVICES = (NTS)

same error

2) Don't Install from mstsc
Did you try creating database through remote or directly server? if remote then try it from directly server.

i tried directly from server. oracle database software installed successfully. After that database creation i am getting this error. After getting ora 12560 tns protocol adapter error
i added tnsnames through NETCA. After that i started dbca i am getting same error. Then i checked tnsnames.ora file the entry i added NETCA is not there in the file.please provide any solution

3)

Are there only one ORACLE_HOME?
Post there sqlnet.ora file context.
Did you get other error messages than ora 12560?

Only ione oracle_home is there.Other than ora 12560 i am not getting any error. The sqlnet.ora file is given below

# sqlnet.ora Network Configuration File: C:\Oracle\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

4)

refer alert.log(C:\Oracle\product\11.2.0\diag\rdbms\<sid>\<db_unique_name>\trace directory)

In trace file i am getting following error in the OraVSSW file.
Could not execute [C:\Oracle\product\11.2.0\dbhome_1\bin\OraVSSW.exe ORAWH /d]; error 1

In this location no file is generated C:\Oracle\diag\rdbms

5)
ORA-12560 running DBCA on Windows 2008 AD Controller [ID 729774.1]

Another Solution:
Install the Oracle Software on a Non-Controller machine.
You can demote the Controller machine to a Member machine.
Perform the install, create the database.
Once everything is installed and setup, you can promote the machine to a Controller.
Be aware, you may have to go through these sames steps if you want to create another Database.

6) ORA-12560 - Database Creation Assistant (DBCA) Fails With TNS Error [ID 747243.1]

Cause
There was no ORA_DBA group and no ORADBA user on the server
System policies removed the group and/or the user used to install Oracl

Solution
After creating the group/user account (by matching the ones on the current production server), the DBCA ran to completion and created the database successfully.

Check with the sys admins to see if there is a policy or process in place to remove certain users and groups. The ORA_DBA group and the Oracle user used for the installation must remain intact.

If the problem remains, after creating the group/user account, you might need to remove Oracle and reinstall the software.

Create Database Structure using Datapump

You can use the INSERT statement to insert data into a table, partition, or view in two ways: conventional INSERT and direct-path INSERT. When you issue a conventional INSERT statement, Oracle Database reuses free space in the table into which you are inserting and maintains referential integrity constraints. With direct-path INSERT, the database appends the inserted data after existing data in the table. Data is written directly into datafiles, bypassing the buffer cache. Free space in the existing data is not reused. This alternative enhances performance during insert operations and is similar to the functionality of the Oracle direct-path loader utility, SQL*Loader.

Direct-path INSERT is subject to a number of restrictions. If any of these restrictions is violated, then Oracle Database executes conventional INSERT serially without returning any message, unless otherwise noted:

You can have multiple direct-path INSERT statements in a single transaction, with or without other DML statements. However, after one DML statement alters a particular table, partition, or index, no other DML statement in the transaction can access that table, partition, or index.

Queries that access the same table, partition, or index are allowed before the direct-path INSERT statement, but not after it.

If any serial or parallel statement attempts to access a table that has already been modified by a direct-path INSERT in the same transaction, then the database returns an error and rejects the statement.

The target table cannot be index organized or part of a cluster.

The target table cannot contain object type columns.

The target table cannot have any triggers or referential integrity constraints defined on it.

The target table cannot be replicated.

A transaction containing a direct-path INSERT statement cannot be or become distributed.

now let’s generate it again but using the transform parameter to reduce the size of it to 70% of original size.

impdp user/password transform=pctspace:70 content=metadata_only directory=datapump dumpfile=ex.dmp

before is to import it telling the Data Pump to reduce the size of extents to 70%

http://oraclenz.wordpress.com/2010/04/29/tip-of-the-month-how-to-have-super-powers-using-data-pump/

http://www.dba-oracle.com/t_data_pump_pctspace.htm

root> impdp transform=pctspace:25

This tells the impdp (import) to re-size the tablespace to 25% of its original size.

when the table actually gets imported than the extent sizes are same.

I used these queries to check some settings:

select file_name, tablespace_name, status

,bytes /1000000 as MB

,maxbytes/1000000 as MB_max

from dba_data_files ;

-- What temporary tablespace is each user using?:

select username, temporary_tablespace, default_tablespace from dba_users ;

-- List all tablespaces and some settings:

select tablespace_name, status, contents, extent_management

from dba_tablespaces ;

TABLESPACE_NAME CONTENTS EXTENT_MAN STATUS

------------------------------ --------- ---------- ---------

SYSTEM PERMANENT DICTIONARY ONLINE

TOOLS PERMANENT DICTIONARY ONLINE

TEMP TEMPORARY DICTIONARY OFFLINE

TMP TEMPORARY LOCAL ONLINE

Now, the above query and the storage clause of the old 'create tablespace TEMP' command seem to tell us the tablespace only allows temporary objects, so it should be safe to assume that no one created any tables or other permanent objects in TEMP by mistake, as I think Oracle would prevent that. However, just to be absolutely certain, I decided to double-check. Checking for any tables in the tablespace is very easy:

-- Show number of tables in the TEMP tablespace - SHOULD be 0:

select count(*) from dba_all_tables

where tablespace_name = 'TEMP' ;

Checking for any other objects (views, indexes, triggers, pl/sql, etc.) is trickier, but this query seems to work correctly - note that you'll probably need to connect internal in order to see the sys_objects view:

-- Shows all objects which exist in the TEMP tablespace - should get

-- NO rows for this:

column owner format a20

column object_type format a30

column object_name format a40

select

o.owner ,o.object_name

,o.object_type

from sys_objects s

,dba_objects o

,dba_data_files df

where df.file_id = s.header_file

and o.object_id = s.object_id

and df.tablespace_name = 'TEMP' ;

(select block_size from dba_tablespaces where tablespace_name='TEMP') d

WHERE b.tablespace = 'TEMP'

and a.saddr = b.session_addr

AND c.address= a.sql_address

AND c.hash_value = a.sql_hash_value

RMAN Block Media Recovery

From Oracle 9i onwards you can use RMAN to recover only blocks while database is up and running.
This could possibly save hours and hours of recovery time as a full database restore is not necessary.
Error reported by user pointing to block corruption.

POPULATE_MACSDATA - ORA-01578: ORACLE data block corrupted (file # 48, block # 142713)
ORA-01110: data file 48: '/hqlinux08db06/ORACLE/macsl/MACSDAT_2006_06.dbf'
ORA-02063: preceding 2 lines from MODSL_MACSL_LINK
File name : /hqlinux08db06/ORACLE/macsl/MACSDAT_2006_06.dbf

Check first if the there is only one(few) blocks corrupted or most of the blocks are corrupted.

macsl:/opt/oracle/admin/macsl/bdump>
Issue command below at UNIX prompt.

dbv file=/hqlinux08db06/ORACLE/macsl/MACSDAT_2006_06.dbf BLOCKSIZE=8192 LOGFILE=test.log

DBV-00200: Block, dba 201469305, already marked corrupted

SQL> Select * from v$database_block_corruption;

You will get block number corrupt.
Ex: block 142713.

After that LOGIN TO RMAN.

rman target / catalog rman10/rman10@rman10p
RMAN> BLOCKRECOVER DATAFILE 48 BLOCK 142713;

V$database_block_corruption is the view to check the list of corrupted blocks.

If you have multiple block list as corrupt, You can use single command to recover them.

RMAN> BLOCKRECOVER corruption list;

Table level Recovery using Flashback Table

---------------------------------------------------Recover Dropped Table from Recyclebin using Flashback Table-------------------------

Oracle Flashback Table enables you to restore a table to its state as of a previous point in time. It provides a fast, online solution for recovering a table that has been accidentally modified or deleted by a user or application. In many

cases, Oracle Flashback Table eliminates the need for you to perform more complicated point-in-time recovery operations.

Oracle Flashback Table:

Restores all data in a specified table to a previous point in time described by a timestamp or SCN.

Performs the restore operation online.

Automatically maintains all of the table attributes, such as indexes, triggers, and constraints that are necessary for an application to function with the flashed-back table.

Maintains any remote state in a distributed environment. For example, all of the table modifications required by replication if a replicated table is flashed back.

Maintains data integrity as specified by constraints. Tables are flashed back provided none of the table constraints are violated. This includes any referential integrity constraints specified between a table included in the FLASHBACK

TABLE statement and another table that is not included in the FLASHBACK TABLE statement.

Even after a flashback operation, the data in the original table is not lost. You can later revert to the original state.

FLASHBACK TABLE <table_name> TO BEFORE DROP;

Some other variations of the flashback database command include.

FLASHBACK DATABASE TO TIMESTAMP my_date;
FLASHBACK DATABASE TO BEFORE TIMESTAMP my_date;
FLASHBACK DATABASE TO SCN my_scn;
FLASHBACK DATABASE TO BEFORE SCN my_scn;

--------------------------------------------------Recover deleted Table Data from Recyclebin using Flashback Table---------------------

On Oracle Database 11g (10gR2...), we can rewind one or more tables back to their contents at a previous time without affecting other database objects.

Before we use Flashback Table, We must enable row movement on the table. because rowids will change after the flashback.

Example: Flashback the table back to previous time using SCN

select count(*) from LDBO.test;
COUNT(*)
----------
68781

SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------
1584494

SQL> delete from LDBO.test where rownum <= 50000;

50000 rows deleted.

SQL> commit;

Commit complete.

SQL> select count(*) from LDBO.test;

COUNT(*)
----------
18781

SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------
1587106

Enable row movement:

SQL> alter table LDBO.test enable row movement;

Table altered.

SQL> FLASHBACK TABLE LDBO.test to scn 1584494;

Flashback complete.

SQL> select count(*) from LDBO.test;

QL> alter table LDBO.test disable row movement;

Table altered.

We can rewind the table back to previous time using timestamp:

SQL> alter session set nls_date_format='YYYY/MM/DD HH24:MI:SS';

Session altered.

SQL> select sysdate from dual;

SYSDATE
-------------------
2009/08/30 17:01:09

SQL> delete from LDBO.test ;

68781 rows deleted.

SQL> commit;

Commit complete.

SQL> select sysdate from dual;

SYSDATE
-------------------
2009/08/30 17:03:18

SQL> select count(*) from LDBO.test;

COUNT(*)
----------
0

SQL> alter table LDBO.test enable row movement;

Table altered.

SQL> flashback table LDBO.test to timestamp TO_TIMESTAMP('2009/08/30 17:01:09','YYYY/MM/DD HH24:MI:SS');

Flashback complete.

SQL> select count(*) from LDBO.test;

COUNT(*)
----------
68781

--------------------------------------------------------------------------------------------Flashback Table recover table to different table----------------------

FLASHBACK TABLE test TO BEFORE DROP RENAME TO test2;

flashback table LDBO.test to timestamp TO_TIMESTAMP('2009/08/30 17:01:09','YYYY/MM/DD HH24:MI:SS') RENAME TO test2;

11g Active Data Guard - enabling Real-Time Query

Active Data Guard is a good new feature in 11g (although requires a license) which enables us to query the Standby database while redo logs are being applied to it. In earlier releases, we had to stop the log apply, open the database in read only mode and then start the log apply again when the database was taken out of the read only mode.

With Oracle 11g Active Data Guard, we can make use of our standby site to offload reporting and query type applications while at the same time not compromising on the high availability aspect.

How do we enable Active Data Guard?

If we are not using the Data Guard Broker, we need to open the standby database, set it in read only mode and then start the managed recovery as shown below.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup

SQL> recover managed standby database using current logfile disconnect;

If we are using the Data Guard Broker CLI, DGMGRL, the procedure is a bit different and is not very clearly explained in the documentation.

You need to stop redo apply first via the SET STATE dgmgrl command, then from a SQL*PLUS session, open the database in read only mode, and then back again from dgmgrl via set SET STATE command, start the redo apply again.

Stop redo apply with the following command from Data Guard Broker CLI

DGMGRL> EDIT DATABASE ‘PRODDB’ SET STATE=’APPLY-OFF’;

Open standby read-only via SQL*Plus

SQL> alter database open read only;

Restart redo apply via broker CLI

DGMGRL> EDIT DATABASE ‘PRODDB’ SET STATE=’APPLY-ON’;

I tried to run the same only via DGMGRL and got this error:

DGMGRL> edit database PRODDB set state=”APPLY-OFF”;
Succeeded.

DGMGRL> edit database PRODDB set state=”READ ONLY”;
Error: ORA-16516: current state is invalid for the attempted operation

After we have enabled the Real-Time Query feature, we can confirm the same via the DGMGRL command – SHOW DATABASE

DGMGRL> show database verbose PRODDB_DR

Database – PRODDB_DR

Role: PHYSICAL STANDBY
Intended State: APPLY-ON
Transport Lag: 0 seconds
Apply Lag: 0 seconds
Real Time Query: ON

Note:

Even though we have enabled Real-Time Query feature, if we go to Data Guard page via the Enterprise Manager Grid Control GUI, it will show that Real-Time Query is in a Disabled state.

This is apparently a bug which applies to OEM Grid Control 10.2.0.1 to 10.2.0.5 with a 11.2 target database.
