Data Guard :: Finding Unapplied Archived Log File In DR?
Sep 21, 2011
I wanted to make a script for applying the Archived log File in to DR by certain interval.
1) I will use the below view for finding the SEQUENCE so far applied.select sequence# from v$log_archive.
2) But how i can compare with the archive log files available in physical location with the above mentioned view.
eg:- the above view shows, the till the sequence 46789 is applied.And in the DR physical Location available sequences are 46795. which means 6 more archived log files are more, which are not applied into the DR so far.

1) How to copy the ARCHIVED LOG FILE from Primary to DR location. Where if the DR is having the file already, how to SKIP that Particular Archived log file?
2) I have Checked with the FILE_TRANSFER DBMS package, but it gives the error if any file existing already.

The GAP archived log can not transport to target database by auto, how can i do?
Sun May 27 06:32:59 2012
FAL[client]: Failed to request gap sequence
GAP - thread 1 sequence 161-161

Check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain adequate log switch information to resolve archivelog gaps.

I got a database on dataguard and my primary (db1) is shipping files to my standby (db2) with no problems.However, when I query:
select sequence#, status, applied from v$archived_log;
I see this:
SEQUENCE# S APP
---------- - ---
4 A YES
5 A YES
6 A YES
7 A YES
8 A YES
9 A YES
10 A YES
11 A YES
12 A YES
13 A YES
14 A YES
[code]....
So I did an alter system switch logfile on db1 then looked again and I can see new archived logs being applied.I thought all archived logs had to be applied on the standby since this is the very foundation of the standby database.Am I going to run in trouble later if I have a failover (unsynchronized database)

1> Does dataguard in 10g use ftp/rsh to transfer archived log files to standby database or some other protocol?
2> In my primary database, archives are getting generated normally, there is no error in alert log file. But archives are not getting transferred to standby database. I am able to connect through sys user from primary server to standby database & vice versa.
Also, tnsping is working fine.
All was working fine till 2 days back & no parameter has been changed from database side. I am not able to transfer the file manually through FTP to standby server. Does it is the problem? Or dataguard doesnt use FTP protocol to transfer the files?

i'm trying to write a pl/sql to find all missing archived logs that are need for streams replication.
There is already a oracle metalink note for this. But yet it would give only the archive log name that contains my dba_capture.start_scn and we need to check if the files exist in disk or not!
The problem here is, when using ASM, dba_registered_archived_log view is truncation the file name and it is really difficult to pin point the logs. So is it fine to join this view with V$archived_log? is deleted and status column would do the trick? I modified the plsql as below. Is this fine/accurate?
CODEdbms_output.put_line('Capture will restart from SCN ' || lScn ||' in the following file:');
for cr in
(select decode (a.name, NULL, 'NOT FOUND', a.name) name, to_char(a.completion_time, 'hh42:mi:ss') completion_time from v$archived_log a,dba_registered_archived_log b where lscn between b.first_scn and b.next_scn
and a.deleted = 'YES' and a.status != 'A')
loop
f_rec :=1;
[code]......

I am in need of a clarification regarding the file size growth in Physical Standby Database.Say we have 150 GB size of LIVE DB and we have created the same as in STDBY(150 GB).Will there be a growth in STDBY DB datafiles with respect to the LIVE DBOR only the logs are applied currently to the STDBY and the changes will only be reflecting when there is a switchover or failure scenario??

What is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?

I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?

I have simple table:
code = CHAR(5) as primary key
name = VARCHAR2(bla blal ba)
There is one-block-form based on this table. Block's datasource type = table and datatarget type = pl/sql procedure
Table API, Module API - all generated, all valid and seems correct. Now.. I try to update "name" from form. As soon as I type in something in the field, I get message "Row no longer exists". When digging deeper it seems that problem raises from lock_prodecure:
DECLARE
bk_data CGC$CL_1_9_DKD.cgc$rec_tab;
BEGIN
PLSQL_TABLE.POPULATE_TABLE(bk_data, 'DKD', PLSQL_TABLE.LOCK_RECORDS);
CGC$CL_1_9_DKD.lck(bk_data);
END;
It seems, it has some problems on populating the "code" attribute in bk_data.
how to solve this problem without massive re-coding??.
