Log sequence number

who updates the log sequence number in control file and datafiles , I know chkpoint is responsible to update checkpoint number in datafile and control file number.

it is LGWR.

Redo log sequence number

hi everyone,
I am looking at our SB system, and try to do only redo log backup. however it comes back with error message: The current redo log sequence number is not greater than the sequence number of the last saved offline redo log file.
So, we suspect that since last refresh, we may reset the sequence back from 1. Any one know how to solve this problem? Thanks in advance.

Hi,
Is your probh solved?
Can u pl tell if u executed a recovery of database earlier?
Pl check if there was a case of reset logs.
To do this run BRTOOLS-->Instance Mgt->Show Inst Status.
This will show if there was a case of reset logs.
If it is so try the following:
Shut down sap and the database.
Look for a folder named oraarch
Oracle/sid/oraarch
Copy all the archive files to another folder and delete all the arc files from the oraarch folder.
The name of the arch files will be like <SID>ARCHARC123456.001
After copying to another location and subsequently deleting them from oraarch folders start up oracle in mount mode.
Then issue the following sql
alter database open resetlogs;
then start sap.
NB:Dont forget to take a complete backup before and after diong this.
Hope this will help.
Most probably your database contains two icarnations of redo log files so this error is comming.

Doubt about CURRENT LOG SEQUENCE NUMBER

I just want to know that why the "current log sequence number" is added to the header of each data file ? why oracle needs to do that ? as it is also added to the control file and whenever it needs to know the current log sequence number , it can get it from control file , then why to add this in the header of data files ?

For Recovery.
When you are doing a Recovery of a database where the datafiles have been restored from backups but the controlfile has been recreated (thus, the controlfile has no information about log sequence numbers and checkpoint scns), the Recovery must read this information from the datafile headers.
Say you have 5 datafiles and they have been backed up 6 months ago using ALTER TABLESPACE BEGIN BACKUP commands and, therefore, have different checkpoint SCNs. The checkpoint SCNs could be 1021, 1059, 1085, 1745, 2045.
How would Oracle know which Log Sequence Numbers are needed ? It knows that a Recovery must start with SCN 1021. But if the information about Log Sequence Numbers is not available in the controlfile (either because it is as of today and the controlfile doesn't store information about 6 months of redo logs OR because the controlfile has been recreated), what is the Log Sequence Number corresponding to that SCN 1021 ?
That information is available in the datafile header. You will NOT see it in V$DATAFILE or V$DATAFILE_HEADER. You will not see it in a level 1 dump of datafile headers.
You will see an example here :

Current log sequence number

i have a small doubt :
when there is log switch , the current log sequence number is stored in the control file . Is the same current log sequence number stored in the headers of the datafiles??????
waiting for your answers eargerly.....
kumaresan.M

nops i don think so.
there is no need for doing this, only controlfile needs to know about the current sequence number

Who writes LOG SEQUENCE NUMBER to CONTROL FILE,whether CKPT or LGWR process

I am in confusion that,
When log switch occurs that time Log sequence no. is generated by LGWR. then after who writes that LSN to CONTROL FILE whether Checkpoint or LGWR.
Please provide me proper answer with example.....

I notice by using fuser on a controlfile on hp-ux, a number of processes keep the controlfile open. So it would make sense that the one that writes logs would write log sequence numbers to the controlfile too.
$ for z in `/usr/sbin/fuser control03.ctl|awk ' {x=split($0,args); for (i=2;i<=x;i++){print args[i]}}'`
        do
            ps -efx|grep $z|grep -v grep
        done

In standby db, can't find sequence number of Last Applied Log.

Hello,
Standby database is behind the primary database for over 200 hours, to repaire this, we are using a incremental backup from primary database and a restored control file.
after starting up standby database, in Grid Control (OEM), can't find "last applied log" sequence number,
go to that standby, do
standby> select max(sequence#) from v$archived_log where applied='YES';
MAX(SEQUENCE#)
go to primary,
do

I appreciate your response......
thanks.

This information shows that the log switch has occured.
The LGWR writes the redo information from the redo log buffer to the online redo log file. When the current online redo log file fills, LGWR begins writing to the next available online redo log file. In the mean time, the ARC process archives the contents of the filled online redo log file (If the database is in archivelog mode. If its in noarchive mode, then the filled online redo log file would not be archived). These archives are given a unique log sequence number.
In your case 253305, 253306..are the log sequence numbers.
You can refer http://docs.oracle.com/cd/B10501_01/server.920/a96521/onlineredo.htm for a detailed information

How I can log Sequence File version number to database?

Hi,
As in the subject.
How I can log Sequence File version number to database?
There is nothing like that under Logging object.

Do you need it in a separate field in the databse?
One option is to just add it as an additional result in a step in your sequence file.
RunState.SequenceFile.AsPropertyObjectFile.Version
Hope this helps,

Error in mail sender channel : invalid sequence number

Hello all,
I'm having the following issue.
I'm using the mail adapter to get messages from a mail server, which are attached to the mail.
This interface is already productive, and is working fine most of the time.
Only frequently I get the following error, which can be found in the java log.
exception caught during processing mail message[630];
java.io.IOException: the specified message not found: -ERR invalid sequence
number
This error seems only to appear when there are a lot of mails to be fetched.
All the mail is read into PI and processed succesfully, only I also get a lot these errors.
Does anyone know what causes this error?
I also don't know where this sequence number is coming from, and what's the meaning of this.
Is it possible it's trying to read the same mail more then once?
The settings in the mail sender channel are:
- transport protocol : POP3
- message protocol : XIPAYLOAD
- Use mail package : enabled
- content encoding : none
- Keep attachments : enabled
- QOS : exactly once
- Set adapter specific message attibutes : enabled
The PI version is 7.01
Thanks a lot in advance for the replies on this question.
Kind regards,
Marco van Iersel

Hi
Well we have used it with POP3 and it is working in the way as it should be.
This feature is recommended by sap when the number of emails to be read is large.
You can set this additional parameter to restrict the number of mails fetched by sender mail adapter in one polling interval.
Sometimes the mailbox configured for the sender mail adapter contains large number of unread mails, which exceeds the average expected number of mails in one polling interval. In such a case, processing of all the unread mails in the same polling interval by sender mail adapter degrades the system performance. To avoid this, set value of this parameter to the maximum number of mails to be fetched and processed in one polling interval. The remaining mails exceeding the limit would be processed in the next polling interval.
That's why I have asked you to give it a try.

Sequence number different in DB than from assignSequenceNumber()

I am using TopLink 10.1.3 DP4 (I think - inside JDev build 3565). I am attempting to use a sequence in a schema that I DO NOT OWN - I cannot make modifications tot he database sequence because there are other applications in place running against it.
The database sequence is in a 10g database, with an interval of 1 and a cache of 20.
My object uses the value of the sequence as the sole element of its primary key. I am creating a new object, registering it with a UnitOfWork using registerNewObject(obj). It seems that this does not make a clone, since the object returned by this method is the same identity as the object passed in.
My project sequencing policy is set as follows:
<project-sequencing-policy>
<sequencing-policy>
<preallocation-size>1</preallocation-size>
<sequencing-type>Use native sequencing</sequencing-type>
<name-field-handle>
<field-handle/>
</name-field-handle>
<counter-field-handle>
<field-handle/>
</counter-field-handle>
<sequencing-policy-table></sequencing-policy-table>
</sequencing-policy>
</project-sequencing-policy>
Platform is 10g
<platform-name>Oracle10g</platform-name>
The sequence is accessed through a synonym (since JDev couldn't seem to reference a sequence in a different schema from a user's login).
<sequence-number-name>EVENT_SEQ_SYN</sequence-number-name>
<uses-sequencing>true</uses-sequencing>
When I commit my new object, I can see the insert statements in the log claiming a value of 'x' for the primary key. The row in the database actually has a primary key of 'y', where 'x = y - preallocation size' and 'y = sequence last number - preallocation size'. I think I would get the right number if I could set the preallocation size to 0 (performance problems understood) but TopLink chokes on this at run-time.
Is this problem familiar to anyone?
Failing using native sequencing, I tried to write custom SQL for the insert statement, but I couldn't find any decent examples anywere on how to do that. I found in a deep google search an example that showed you could use hash (#) to reference the value of a property, but what if the value that needs to be inserted in the database is held in an indirect referenced object? For example, if I was trying to write an insert sql for a Pet object with an indirect reference (valueHolder) to its owner, and I needed to put the owner id in the row - how would I write that insert statement in the 'custom sql' pane in workbench?
Thanks for your help.
Dave

Very strange case.
I tried to reproduce it using TopLink Employee example - and couldn't.
Here's the code:
    // to get debug info
    session.setLogLevel(SessionLog.ALL);
    session.login();
    UnitOfWork uow = session.acquireUnitOfWork();
    Employee emp = new Employee();
    emp.setFirstName("sequencingTest");
    uow.registerNewObject(emp);
    uow.assignSequenceNumber(emp);
    uow.commit();
    System.out.println("firstName = "+emp.getFirstName() +"; id="+ emp.getId());And here's the log:

If I understood correctly, the problem is x showing up in insert as a value to be assigned to PK and y actually inserted into the db. If that's the case could there be a BeforeInsert trigger on the table? To test try inserting through jdbc using concrete pk value.

Sequence number in filenames

Hello,
When DB dumps next segment of its log, new files are named autolog_name.XXX, where XXX is my problem. I thought that when I perform full backup, this number will reset and start with "001" but it did not
How can I reset this sequence number in filenames generated by autolog?

Nope - you can always use an "older" backup and apply the archive logs, this is the same as using a newer backup and use newer archivelogs.

If you have a problem with the backup for whatever reason, you won't be easily be able to recover an "older" one with that scenario. I have no idea, what problem you have with the "filenamenumbers" but if that is ok for you it's for me too
