SXMSCLUP (Archive/Delete) - Undo space in LOB

I've openned a ticket with SAP, but I figured I would get additional input
My SXMSCLUP LOB segment continues to grow. We are successfully running the archive/deletion process successfully. We've noted that even though data is deleted is still saved in the LOB segment; I believe this is the source of the unexpected growth.
SXMB_ADM there is a parameter Deletion PERSIST_DURATION HISTORY; the lowest this can be set is 7 days. (We generate tons of messages mostly due to FSCM Credit Worthiness calls).
How are others managing this table in a highly transactional system? This table is constantly in flux, I'm not sure why SAP would put data in a lob segment given the amount of changes.
*I have logging turned on, unfortunately its "all or nothing" if I could avoid logging the FSCM calls it would be a great help, but I have not seen the functionality to "choose" which messages to log.
Thanks

Hello,

PI 7.1 Archiving - Delete

hi Team,
We have PI 7.1 production environment and planning to implement ARCHIVING & DELETE for Integration Engine, Adapter Engine and Business Process Engine based messages.
I had referred to 'How to arhive & delete' doc that highly available in SDN but few question after going through the doc.
1. If a interface flagged for ARCHIVING then all messages in complete message status gets automatically Archived
2. And if interface not flagged for ARCHIVING then all messages of those interfaces gets automatically Deleted
Ofcourse on these both the cases, the corresponding action takes place only provided the retention period candition meets.
1. But Wondering, How about the messages that NOT successfully processed? Somewhere in SDN i red the NOT completetly proccessed messages require to be first 'Cancelled' and then they get marked for ARCH so that it gets archived! So in this case, both 'Synchronous" and "Asynchronous" not completely proccessed messages have to be marked for 'Cancel' before they get Archived?
2. Keeping this aside how the not completely processed archving, Why we need to archive the messages that are not completely proccessed in PRODUCTION environment?
3. In regards to 'NOT Completely processed' messages, I agree to certain extend that "All these have to be removed" from Database so that we gain disk space that helps improve the performance also? Please share your knowledge.
4. Either Archiving or Delete mechanism has any dependance or functional variations on Synchronous and Asysnchronous?
I highly appriciate all those add their knowledge here to clarify
Regards
Sekhar

Dear Sekhar,
let me go through your questions step by step...
1. But Wondering, How about the messages that NOT successfully processed? Somewhere in SDN i red the NOT completetly proccessed messages require to be first 'Cancelled' and then they get marked for ARCH so that it gets archived! So in this case, both 'Synchronous" and "Asynchronous" not completely proccessed messages have to be marked for 'Cancel' before they get Archived?
This is almost correct. Canceling is required for asynchonous messages in error state only. By canceling a message its state changes from error to final and this it is allowed to be archived. In contrast synchronous messages are final right when processing fails.
Please note: archiving applies to asynchronous messages only. It is a general decision by SAP to not archive synchronous messages.
2. Keeping this aside how the not completely processed archving, Why we need to archive the messages that are not completely proccessed in PRODUCTION environment?
Once an asynchronous message enters the central Intergation Server(IS) or the local Integration Engine(IE) XI/PI takes over responsibility for this message. Canceling a message means a serious violation of the EO/EOIO protocol. This violation needs to be documented in productive environments for the purpose of tracebility.
3. In regards to 'NOT Completely processed' messages, I agree to certain extend that "All these have to be removed" from Database so that we gain disk space that helps improve the performance also? Please share your knowledge.
I am not quite sure that I got the point. For each message entering the IS/IE SAP has to provide a guided procedure to reorganize this message. For successfully processed messages this is done by standard house-keeping jobs for archivng and deletion. For messages in error state there are basically two ooptions:
(1) restert message after error has been fixed;
- if message processing is sucessful this time, we are back to normal
- if message processing fails again, we are in the very same siutation as before
(2) cancel messages; this males the message 'final' and then it is treated like sucessfully processed messages.
Thus, this is all about defining an end point in the lifecycle of each message.

Can I delete Undo-Data?

Hi all, my harddisk is almost full and I want to make some space.
I found out there's a folder which contained 15 Gbyte of Undo data...
It is located over here:
Application Support/Logic/Undo/Undo Data
What does Logic do with it? Can I erase the data?
Hope someone can help me.....

Sounds like you never set your preferences in Logic to Delete Undo History when quitting. So all the undo data from as long as you have been working in Logic 7 has accumulated.
Chances are, that much, if not most of that, is undo data for songs you probably have long since finished.
If you don't have any need or desire to revisit any of those songs, or more importantly, think that you would possibly need or want to undo any edits made way back when, then yes, go ahead and delete the contents of that folder.
And when you get a chance, change that preference in Logic, so that when you quit the song for the day, your undo history is cleared. That will help keep this from happening again, over time.

Does a normal view write to any log i.e archive or undo log

Hi ,
can i check if a normal view writes to the archive or undo log ?
e.g
select a.* , b.* from A , B
tks & rdgs

SELECT statements, including those that are selecting views, aren't making any data changes, so there would be no reason to generate UNDO or REDO log entries. There would be nothing to undo or to redo.

Message archiving/deletion in PI 7.1

Hi All,
I'm new to SAP PI. We have newly implemented PI 7.1 in our landscape. We have installed PI in HP UX 23 with oracle as the database.
We have configured the messge archival/deletion in our PI production server. We have allocated a dedicated file system to store the archived messages. Eventhough we have maintained the path of the archival_interface, no messages are archived in this drectory.
We are using synchronous interfaces and while executing the report ( RSXMB_SHOW_REORG_STATUS ) as per the note 872388, the report says that there are more than 1700 messages to be archived. But no messages are getting archived in the path mention as of now.
I think we have missed out some steps while configuring the archiving process. Can somebody help me with the steps involved in PI integration engine message archival/deletion.
Your timely help will be much appreciated.
Thanks in advance.
Regards,
Varadhu

Hi,
Go to transaction "SXMB_ADM" on the ABAP stack of your XI installation. Go to "Integration Engine Configuration" and click on tab "Specific configuration". Check if you have the parameter "LOGGING_SYNC" enabled (It should have a value 1). In case it is not present, please create this entry and have the default value as "1". This will enable you to view all sync messages on sxmb_moni.
Thanks,
Sidhartha

Issue with Archiving & Deletion of messages in PI ,SXMB_MONI messages

Hello experts
I am working on Archiving & Deletion of messages in PI ,SXMB_MONI, i have fallowed all the steps which are avialable in /people/deepak.shah/blog/2010/04/22/archiving-deletion-of-messages-in-pi--part-2, but the messages still there in SXMB_MONI.
please help me to resolve this issue.
regards
chandra

Hi Krish
i have fallowed steps like....
in SXMB_ADM
>>>step 1: Define the interface for archivng and retnetion period
>>>step2):Schedule Archive Jobs,
after this i have checked the in SM37 the jobs got sheduled and released after that it showing finished.
>>>step3):ARV_BC_XMB_WRP<date> (archiving, step 1)
ARV_BC_XMB_DEL<date> (archiving, step 2)
here i am getting message like "0 XML messages got archived".
"0 XML message for deleated".
I have doubt in SXMBPMAST table here when i check the status of interface , ITFACTION field is containing the value INIT and if I understood correctly it job deletes only those messages where ITFACTION is set to DEL.
We are actually trying to delete the messages avoiding archiving but what I am seeing is we cannot delete error messages and for them we must have to go through archiving. Please correct me if I am wrong.
Thanks

Deleting blank spaces in internal table

Hi Gurus,
I want to delete the empty spaces of a particular field in internal table.I used condense and shift statements but didnt work because the work area value is already condensed.I am not sure why the internal table field is having so much of empty spaces to its left.It's a character field with length 60.
Please suggest.

Hi,
This is the rellevant code
LOOP AT IT_HIER INTO WFL_HIER.
        WFL_FINAL-NODEID = WFL_HIER-NID.
        WFL_FINAL-IOBJNM = WFL_HIER-IOBJ.
        WFL_FINAL-NODENAME = WFL_HIER-NNAME.
        WFL_FINAL-PID = WFL_HIER-PID.
        condense wfl_hier-desc.
        WFL_FINAL-DESCRIPTION = WFL_HIER-DESC.
        SHIFT WFL_FINAL-DESCRIPTION LEFT DELETING LEADING SPACE.
        APPEND WFL_FINAL TO E_T_DATA.
        CLEAR WFL_FINAL.
        CLEAR: WFL_HIER,OUT.
      ENDLOOP.
The problem is not with the work area.
Say if I have a value apple in the work area wa, (wa - 'apple').
It doesnt have any leading sapces to the left.
But when I am appending it to the internal table it gets posted at the last say like this (it - '                                       apple'.
It occupies the last five characters.
Not sure how to resolve this.

A small but very irritating bug in Mail: after pressing the spacebar after typing an apostrophe in a word such as "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.

When composing an email in Mac Mail I've noticed a small but very irritating bug: pressing the spacebar after typing an apostrophe in a word, e.g. "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.
Any ideas?

I just recreated this problem on my iMac (wired KB, no wireless KB) by changing Mail > Preferences > Composing > Spellcheck from "as I type" to "never". Then type a contraction ending in 're and the space bar causes the cursor to jump back as others have stated, to the spot 'r|e
Next, I went into System Preferences > Keyboard > Text, and turned off "use smart quotes" and the problem went away again.
From this point (smart quotes off, spell checking never), if I turn Smart Quotes ON, the problem returns.
The problem is dependent on the state of both settings.
The spacebar in Mail "works" if I have either of the following setting combinations:
Keyboard: smart quotes OFF, Mail: check spelling ANY SETTING
Keyboard: smart quotes ON, Mail: check spelling AS I TYPE
Other combinations FAIL
Keyboard: smart quotes ON, Mail: Check spelling NEVER
Keyboard: smart quotes ON, Mail: Check Spelling WHEN I CLICK SEND
Looks to me like there's a bug in Mail > Preferences > Check spelling > NEVER and WHEN I CLICK SEND that interacts badly with Keyboard > Smart quotes ON.
Thanks.

Archival/Deletion of messages in XI 3.0 SP23

Dear All,
We need to carry out a data deletion/purging activity at our XI box, where no archival/deletion policy has been incorporated ever. As a preparatory measure, I need to have some guidelines for the activities as under,
1. While defining an Archival policy, is there any recomendation from SAP or others that message archival exercise has to be carried out first, before proceeding with message deletion? To be more precise, can we directly delete/purge the messages without archiving them? What will be the impact of such an exercise on the XI system?
This point may sound confusing but the reality is that we do not have enough H/W to carry out an activity of Archival and Deletion.
2. What is the SAP recomendation/best practice in this regard?
3. Although we are defining the Archival/Deletion policy now, we need to purge data that is 3 years old and we do not require them any more. What would be the best practice to carryout this activity?
Thanks and regards,
Sugata Basu

Hi Sugatada,
is there any recomendation from SAP or others that message archival exercise has to be carried out first, before proceeding with message deletion?
No as per my knowledge..
can we directly delete/purge the messages without archiving them? What will be the impact of such an exercise on the XI system?
This wholly depends on requirement...if the data is too old...you can directly delete it..no need to archieve..
What is the SAP recomendation/best practice in this regard?
you can set these values which close to best practice...
Retention period for both synch and asynch
msgs without error awaiting deletion : 180 days
msgs without error awaiting archieving : 45 days
retention period for history entris for deleted msgs : 30 days
in XI we have 2 types of action:
(1) deletion of XML messages (without prior archiving)
(2) archiving of XML messages with subsequent deletion
SAP_BC_XMB_DELETE* for type (1)
SAP_BC_XMB_ARCHIVE* for type (2)

What happens when UNDO space is full? Transaction takes more time to ERROR?

I have a long running transaction (more than 3 hours), and at the same time other operations are occurring on different tables, using the same UNDO space.
Sometimes we see ORA-30036, but this error occurs very late in the process.
The transaction normally takes 3 hours, but when UNDO space is full, we do not get ORA-30036 upto 8 hours or 9 hours of process.
I am wondering what could be happening in the background, when UNDO space is full, whcih makes the transaction to extend upto 8 hours or 9 hours (pl. note, this transaction gets completed within 3 hours normally).
This is in 11g, UNDO space is managed manually.
Any clues? Thanks in advance.

If it is set to non-zero value, Oracle will suspend SQL statement execution if it runs out of certain resources, and running out of UNDO space is one of them. SQL statement execution will be suspended for RESUMABLE_TIMEOUT seconds giving DBA time to fix space issue. Then SQL statement execution will contitue. If issue is not fixed within RESUMABLE_TIMEOUT, statement will fail.

Archive / Delete Q-INFO records

Hello ,
Which object in sara code should i use/create to archive/delete Q info records ?
Thx in advance .

Hi
I am not very sure about archiving of the Quality info record but
Deletion is possible only by putting the Deletion Indicator to the same in T code QI02 screen -->"deletion Screen"
I hope this will add some value.

your earlier reply surely appreciated .......

Hi Rajesh,
I think SAP help says that the period for which you are planning to delete or archive data may have to be locked.
Check the following links:

UNDO SPACE DURING SNAPSHOT REFRESH

Hi All,
I am seeing a weird issue with mu undo space in oracle 10g 10.2.0.3.
Problem is ....
I am doing a complete snapshot refresh from a remote database to source database. When I do this the snapshot refresh is consuming my all undo, I can see this by executing
select distinct segment_name,sum(bytes)/1024/1024/1024 from dba_segments where tablespace_name='UNDO_TBS' group by segment_name;
SEGMENT_NAME SUM(BYTES)
_SYSSMU16$ 39.931324
My total undo space is 40GB
Why the snapshot refresh is consuming all the undo. Any idea? Appreciate your help.

Hi,
You can use the undocumented parameter "_mav_refresh_consistent_read" - refresh materialized views using consistent read snapshot (it will reduced the undo log issues).
The Basic problem is "ATOMIC_REFRESH" is true or enable. try to make it false and check
ATOMIC_REFRESH=>false
Example :- execute DBMS_MVIEW.REFRESH(''view_name,'C’,ATOMIC_REFRESH=>false);

RSEXARCD: Idoc archiving deletion program issues

Hi,
I have two queries:
1. The Idoc archive deletion program, RSEXARCD, when executed in background, terminates when there are no archive files to process (as seen in SARA). How can we prevent this? Our deletion jobs are scheduled weekly, but sometimes there are no archive files created from the archive write program RSEXARCA.
2. Secondly, how can we process multiple archive files using this program RSEXARCD in background? Currently, it processes only one archive file at a time and takes up the oldest unprocessed archive file. Also, would like to know how it gets this information of the oldest unprocessed archive file?
Thanks.

if a program terminates, then you should look into the dump to see the root cause and follow the instructions. e.g. search for OSS notes with the metioned terms
I just searched with the terms "archiving idocs termination" and found 12 notes with program fixes.
Further, the program names you mentioned are not the most recent programs.
Have a look into OSS note Note 582828 - IDoc archiving: Standardization
maybe you will not have your problems anymore if you use the new programs
