Datapump Use In Remote Servers
Nov 19, 2008
We have eight servers. One of them is for centeral management. The other seven is for development and test databases. Every night, we start a process which exports database schemas (without data) into the centeral server. An example of the process we run is just like below:
CODEcd /data1/backup
mknod exp_pipe_oracle1 p
compress<exp_pipe_oracle1>dev.dmp.Z&
exp user/****@dev file=exp_pipe_oracle1 owner=schema1,schema2,schema3 statistics=none rows=n log=dev.log
As you can see, we use @dev to connect remote database. But dump file is created in local (centeral) server. We are planning to use datapump instead of classic export in future. But I couldn't find a solution, that could take a database export in a remote server and create dump file in local. I have looked at NETWORK_LINK parameter; but it doesn't seem to work for our case.
Is it possible to backup a remote database with datapump and make it create dumpfile in local? (Of course we can use some solutions such as NFS, but we really not prefer this; if datapump has ability to remotly backup.)

Is the 12c version of the Grid Control only for Oracle Cloud? Not completely sure of exactly what cloud computing is. Looks like a conglomeration of shared resources. Anyway we are converting all of our servers over to vmware virtual machines except the ones we manage in other states. I am upgrading each database to 11 r2 as we convert the servers. Anyway my Grid server is next to convert to a virtual machine. I am using Grid Control 10.2.0.5.0 now. I want to upgrade to the latest version of the Grid control. 12c seems to stress and boast about managing the "Oracle Cloud" to manage regular single node Oracle servers as well as vmware virtual machines?

I wanted to practice dataguard in oracle. I feel that I can practice realistically if I have 2 different servers to do switchovers, building new physical standby database from scratch and shipping the archiving logs from primary to physical standby database, etc., Can I use VMWare software to install 2 different servers and then practice dataguard?

How do I get a list of all servers associated with linked databases?
for example: I have an entry in TNSNAMES.ora:
PTSYS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = BMSQL2.BEAM.LOCAL)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PTSYS)
)
)
if I link this database as follows:
create public database link SourceDB --@PTSYS
CONNECT TO sysadm IDENTIFIED BY password
using
'PTSYS';
How can I tell that this database is on the BMSQL2 server?

I have a two node RAC on 11.2.0.3. We are using SCAN Listener here. On my node 1, i can connect to the database using tns alias: The alias looks something like:
Prod =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = x1200.prod.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cusms)
(UR = A)
)
)
sqlplus system/actdbasystem@cusms ----- works sucesfully on the prod server. Even the same prod alias copied to second tnsnames.ora in the cluster and run, it works sucesful too. But the issue is, when we copy the same alias onto any other servers and try to connect give's the following error message:
SQL*Plus: Release 11.2.0.3.0 Production on Fri Jul 27 12:37:55 2012
Copyright © 1982, 2011, Oracle. All rights reserved.
ERROR:
ORA-12519: TNS:no appropriate service handler found
[code]...
why is it my connection using sqlplus works locally and not from other servers?

I know how to create a database link between two oracle servers, but problem is that SID is same for both servers, Is there any other way to connect two servers without using only 'SID' ..here are TNSNAMES.ORA FILE i HAVE
D.w=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL = TCP)
(HOST=ff.ffc.pic.com)
(PORT = 1521)
[code].......
Is there any other way rather that this
Create database link a connect to username identified by password using 'SID';
Any alternative like using SID.A.w or how I can differentiate these two SID s.

We are facing space crunch in our 4 development 11i ERP environment servers and decided to reclaim the space . We are having 11.1.0.7 Database . What we observed is, there are many objects present in the recyclebin and we went on to purge the reclybin of MSC user.
SQL>select owner,sum(space)* 8 / 1024/1024 "Size in GB" from dba_recyclebin group by owner order by sum(space) ;
OWNER Size in GB
--------------- ----------
MSC 127.672485
IRCUS 22.5664063
GL 2.98492432
APPS .38079834
XXDII_ESB .192993164
APPLSYS .001159668
TMPBKP .000427246
But even after purging the recycle bin of MSC User , we didn't find any changes in DBA_FREE_SPACE for those tablespaces in which recyclebin objects were present. We would have seen the freed space in dba_free_space.

Our application servers will be running a SELECT which returns zero rows all the time.This SELECT is put into a package and this package will be called by application servers very frequently which is causing unnecessary CPU.
Original query and plan
SQL> SELECT SEGMENT_JOB_ID, SEGMENT_SET_JOB_ID, SEGMENT_ID, TARGET_VERSION
FROM AIMUSER.SEGMENT_JOBS
WHERE SEGMENT_JOB_ID NOT IN
(SELECT SEGMENT_JOB_ID
FROM AIMUSER.SEGMENT_JOBS) 2 3 4 5 ;
[code]....
Which option will be better or do we have other options?They need to pass the column's with zero rows to a ref cursor.

1. exp custom/custom FILE=expgt.dmp TABLES=raj.GENERAL_TABLE QUERY = \"WHERE to_date\(lchg_time\) \= \(select db_date from mtda\) \" indexes=n statistics=none
2.exp custom/custom FILE=expdata.dmp TABLES=raj.BAL_TABLE,raj.GEN_TABLE ,raj.CREDITS_TABLE QUERY = \"WHERE to_date\(lchg_time\) \>= \(select db_date from mtda\) \" indexes=n statistics=none
in the second one there tables to the same dmp file with the same where clause

I have a problem to read in data from dmp file to target table.
I've created a dmp file using:
CREATE TABLE table_name
ORGANIZATION EXTERNAL
(TYPE oracle_datapump
DEFAULT DIRECTORY directory_name
LOCATION ('file_name.dmp')
) AS SELECT col1, col2, col3 from source_table;
[Code]...
The file created via db_link from target db to remote db and then the data are insterted into target db table target_table.
desc target_table
col1 varchar2(20)
col2 number
col3 number
There are no values longer than 20 characters in source table, but when I insert into target_table(col1, col2, col3) as select col1, col2 col3 from source_table; I get ORA-12899: value too large for column "target_table"."col1" (actual: 25, maximum: 20).
I gues it has something to do with how the oracle datapump stored the data in dmp file. When I select col1 from source_table where length(col1) > 20; I get two values which clearly are not longer than 20 characters.
Selected values are:
748473358
693197674
where the bug is hidden or any "normal" workaround?

I am receiving two large export files from a vendor, so I have no control over the contents. I need to import these into our database. The two export files are very similar, except the one has slightly differenet columns in it. So, export file 1 may have a table:
COLUMN_A
COLUMN_B
COLUMN_C
The second file may have:
COLUMN_A
COLUMN_B
COLUMN_D
At the destination, I have a table that has:
COLUMN_A
COLUMN_B
COLUMN_C
COLUMN_D
Is there a parameter that would let me interchangably import either (or both) files into this destination table? This is my first attempt at data pump - but I know using import this has caused me issues. Not sure if the same limitations exist? Will the missing columns cause it to fail?

we have daily partitioned table, and for backup we are using data pump (expdp). we policy to drop partition after backup (archiving).
we have archived dump files for 1year, few days back developer made changes with table structure they added one new column to table.
Now we are unable to restore old partitions is there a way to restore partition if new column added / dropped from currect table.

have 2 Oracle server. One with Suse Linux (Oracle 10.2.0.4.0) and one with Windows 2003 Server x64 (Oracle 11.2.0.1.0).
I made a mistake by installing Oracle 11 x32 on a x64 server. Nevertheless it works for about half a year. Then my backups
with datapump don't work. I changed the SGA_TARGET down to 1024M and the datapump works again. Now I want to renew the Windows server and want to import the datapump schemes to the Linux server.

We have three instances on the RAC, When I create a directory is there a default instance that it gets created on? When I execute an datapump export on instance 1, it works but on 2 and 3 it fails with error relating to directory.
Error -
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation

Currently we are using "exp and imp" utilities to unload from production and load into Dev server. While importing, we are following below steps
(1) Load only data [by specifying INDEXES=N in the par file]
(2) Unlock statistics
(3) Load indexes, other objects [by specifying ROWS=N]
After doing these steps, both data, indexes and others objects are loaded. To verify indexes, we are checking DBA_INDEXES.
DBA_INDEXES :
-------------
OWNER INDEX_NAME TABLE_NAME STATUS LAST_ANALYZED
----- ---------- ---------- ------ -------------
MYSCH CP_INDEX_1 CP_TABLE_1 VALID 14/JAN/12
Question :-
(1) Does imp utility rebuild the indexes while loading data ? or it simply takes the rows from dump and load into test system without building from scratch ?
(2) I am trying to replace 'exp' and 'imp' with datapump utilities ? But, I am confused about the parameters to be used ?
(a) Can I load both data and meta data at the same time (Using CONTENT=ALL option) ?
(b) I am planning to implement this in two steps :
first load only metadata using - CONTENT=METADATA_ONLY TABLE_EXISTS_ACTION=REPLACE
then, load data - CONTENT=DATA_ONLY.
