Resetting SCN from removed Capture Process
I've come across a problem in Oracle Streams where the Capture Processes seem to get stuck. There are no reported errors in the alert log and no trace files, but the capture process fails to continue capturing changes. It stays enabled, but in an awkward state where the OEM Console reports zeros across the board (0 messages, 0 enqueued), when in fact there had been accurate totals in the past.
Restarting the Capture process does no good. The Capture process seems to switch its state back and forth from Dictionary Initialization to Initializing and vice versa. The only thing that seems to kickstart Streams again is to remove the Capture process and recreate the same process.
However my problem is that I want to set the start_scn of the new capture process to the captured_scn of the remove capture process so that the new one can start from where the old one left off? However, I'm getting an error that this cannot be performed (cannot capture from specified SCN).
Am I understanding this correctly? Or should the new Capture process start from where the removed left off automatically?
Thanks
Hi,
I seem to have the same problem.
I now have a latency of round about 3 days while nothing happened in the database so I want to be able to set the capture process to a further SCN. Setting the Start_SCN gives me an error (can't remember it now unfortunately). Somethimes it seems that the capture process gets stuck in an archived log. It then takes a long time for it to go further and when it goes further it sprints through a bunch of logs before it gets stuck again. During that time all the statuses look good, no heavy cpu-usage is monitored. We saw that the capture-builder has the highest cpu-load, where I would expect the capture-reader to be busy.
I am able to set the first_scn. So a rebuild of the logminer dictionary might help a bit. But then again: why would the capture process need such a long time to process the archived-logs where no relevant events are expected.
In my case the Streams solution is considered as a candidate for a replication solution where Quest's Sharedplex is considered to be expensive and unable to meet the requirements. One main reason it is considered inadaquate is that it is not able to catch up after a database-restart of a heavy batch. Now it seems that our capture-process might suffer from the same problem. I sincerly hope I'm wrong and it proofs to be capable.

Good way to map SCN = LCR in Capture process?
How does one determine which SCN a LCR comes from? I found a number of undocumented yet potentially relevant views (v$LOGMNR_TRANSACTION, x$lcr, etc), but... well, being undocumented I have to make a number of guesses. grin
We are attempting to disable the Propagation/apply process once a specific SCN has been applied. If you have another suggestion how to accomplish this, please let me know. I have been trying to make my way through the various online documents, but as you probably are well aware of, there is a lot of information to digest.
TIAThanks. The tip about dbms_apply_adm is a good one, and I am looking more into it. Having trouble with dba_apply_progress, though. Or, more accurately, having trouble finding a captured SCN that I trust. dba_capture on the downstream database (not target) shows me a lower number for captured_scn than LAST_ENQUEUED_SCN. Based on what I see in the target, I am leaning towards trusting the enqueued_scn and dba_apply_progress.APPLIED_MESSAGE_NUMBER.

Capture process issue...archive log missing!!!!!
Hi,
Oracle Streams capture process is alternating between INITIALIZING and DICTIONARY INITIALIZATION state and not proceeding after this state to capture updates made on table.
we have accidentally missing archivelogs and no backup archive logs.
Now I am going to recreate the capture process again.
How I can start the the capture process from new SCN ?
And Waht is the batter way to remove the archive log files from central server, because
SCN used by capture processes?
Thanks,
Faziarain
Edited by: [email protected] on Aug 12, 2009 12:27 AMUsing dbms_Streams_Adm to add a capture, perform also a dbms_capture_adm.build. You will see in v$archived_log at the column dictionary_begin a 'yes', which means that the first_change# of this archivelog is first suitable SCN for starting capture.
'rman' is the prefered way in 10g+ to remove the archives as it is aware of streams constraints. If you can't use rman to purge the archives, then you need to check the min required SCN in your system by script and act accordingly.
Since 10g, I recommend to use rman, but nevertheless, here is the script I made in 9i in the old time were rman was eating the archives needed by Streams with appetite.

2=half, 3=a third, 4=a quater .... [ default=2 ]
-z Check if log is still needed by logminer (used in streams),
it requires -i <sid> and also -g for Oracle 8i
This program list, delete or move half of all file whose extention is given [ or default 'arc']
It check the size of the archive directory and if the percentage occupancy is above the given limit
then it performs the action on the half older files.
How to use this prg :
run this file from the crontab, say, each hour.
example
1) Delete archive that is sharing common arch disk, when you are at 85% of 2500 mega perform delete half of the files
whose extention is 'arc' using default affected file (default is -r 2)
0,30 * * * * /usr/local/bin/watch_arc.sh -e arc -t /arc/POLDEV -s 2500 -p 85 -d -v /var/tmp/watch_arc.POLDEV.log
2) Delete archive that is sharing common disk with oother DB in /archive, act when 90% of 140G, affect by deleting
a quater of all files (-r 4) whose extention is 'dbf' but connect before as sysdba in POLDEV db (-i) if they are
applied (-f is a dataguard option)
watch_arc.sh -e dbf -t /archive/standby/CITSPRD -s 140000 -p 90 -d -f -i POLDEV -r 4 -v /tmp/watch_arc.POLDEV.log
3) Delete archive of DB POLDEV when it reaches 75% affect 1/3 third of files, but connect in DB to check if
logminer do not need this archive (-z). this is usefull in 9iR2 when using Rman as rman do not support delete input
in connection to Logminer.

Capture process status waiting for Dictionary Redo: first scn....
Hi
i am facing Issue in Oracle Streams.
below message found in Capture State
waiting for Dictionary Redo: first scn 777777777 (Eg)
Archive_log_dest=USE_DB_RECOVERY_FILE_DEST
i have space related issue....
i restored the archive log to another partition eg. /opt/arc_log
what should i do
1) db start reading archive log from above location
or
2) how to move some archive log to USE_DB_RECOVERY_FILE_DEST from /opt/arc_log so db start processing ...
Regard'sHi -
Bad news.
As per note 418755.1
A. Confirm checkpoint retention. Periodically, the mining process checkpoints itself for quicker restart. These checkpoints are maintained in the SYSAUX tablespace by default. The capture parameter, checkpoint_retention_time, controls the amount of checkpoint data retained by moving the FIRST_SCN of the capture process forward. The FIRST_SCN is the lowest possible scn available for capturing changes. When the checkpoint_retention_time is exceeded (default = 60 days), the FIRST_SCN is moved and the Streams metadata tables previous to this scn (FIRST_SCN) can be purged and space in the SYSAUX tablespace reclaimed. To alter the checkpoint_retention_time, use the DBMS_CAPTURE_ADM.ALTER_CAPTURE procedure.
Check if the archived redologfile it is requesting is about 60 days old. You need all archived redologs from the requested logfile onwards; if any are missing then you are out of luck. It doesnt matter that there have been mined and captured already; capture still needs these files for a restart. It has always been like this and IMHO is a significant limitation for streams.
If you cannot recover the logfiles, then you will need to rebuild the captiure process and ensure that any gap in data captures has been resynced manually using tags tofix the data.

Oralce streamsSystem Change Number (SCN) and capture process
Do we have get SCN before capture process is started ? If yes , from where does the replication is started .
WIll replication process startright from the time when SCN is captured
OR
will replicaion start from the time when the capture process is started
Edited by: [email protected] on Mar 26, 2009 6:04 PMI am trying to setup oracle streams to enable replication for a set of tables.
One of the step as per the doc is is to setup/get SCN and its acheived by the following peice of code.
CONNECT STRMADMIN/STRMADMINPW@<CONNECT_STRING_SOURCE>
DECLARE
V_SCN NUMBER;
BEGIN
V_SCN := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();

SOURCE_OBJECT_NAME => '<SCOTT.EMP>',
SOURCE_DATABASE_NAME => 'SOURCE_DATABASE',

You had to reinstall CS6 after cancelling the CC as both were from the same Adobe ID. You can always use & keep both CC & CS6 together.

CAPTURE process error - missing Archive log
Hi -
I am getting cannot open archived log 'xxxx.arc' message when I try to start a newly created capture process. The archive files have been moved by the DBAs.
Is there a way to set the capture process to start from a new archive ?
I tried
exec DBMS_CAPTURE_ADM.ALTER_CAPTURE ( capture_name => 'STRMADMIN_SCH_CAPTURE', start_scn =>9668840362577);
I got the new scn from DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();.
But I still get the same error.
Any ideas ?
Thanks,
SadeepaIf you are on 9i, I know that trying to reset the scn that way won't work. You have to drop and recreate the capture process. You can leave all the rules and rulesets in place, but I think you have to prepare all of the tables again.

The (stopped) Capture process & RMAN
Hi,
We have a working 1-table bi-directional replication with Oracle 10.2.0.4 on SPARC/Solaris.
Every night, RMAN backs up the database and collects/removes the archive logs (delete all inputs).
My understanding from (Oracle Streams Concept & Administration) is that RMAN will not remove an archived log needed by a capture process (I think for the logminer session).
Fine.
But now, If I stop the Capture process for a long time (more than a day), whatever the reason.
It's not clear what is the behaviour...
I'm afraid that:
- RMAN will collect the archived logs (since there is no more logminer session because of the stopped capture process)
- When I'll restart the capture process, it will try to start from the last known SCN and the (new) logminer session will not find the redo logs.
If that's correct, is it possible to restart the Capture process with an updated SCN so that I do not run into this problem ?
How to find this SCN ?
(In the case of a long interruption, we have a specific script which synchronize the table. It would be run first before restarting the capture process)
Thanks for your answers.
JDRMAN backup in 10g is streams aware. It will not delete any logs that contain the required_checkpoint_scn and above. This is true only if the capture process is running in the same database(local capture) as the RMAN backup is running.
If you are using downstream capture, then RMAN is not aware of what logs that streams needs and may delete those logs. One additional reason why logs may be deleted is due to space pressure in flash recovery area.
Please take a look at the following documentation:
Oracle® Streams Concepts and Administration

Instantiation and start_scn of capture process
Hi,
We are working on stream replication, and I have one doubt abt the behavior of the stream.
During set up, we have to instantiate the database objects whose data will be transferrd during the process. This instantiation process, will create the object at the destination db and set scn value beyond which changes from the source db will be accepted. Now, during creation of capture process, capture process will be assigned a specific start_scn value. Capture process will start capturing the changes beyond this value and will put in capture queue. If in between capture process get aborted, and we have no alternative other than re-creation of capture process, what will happen with the data which will get created during that dropping / recreation procedure of capture process. Do I need to physically get the data and import at the destination db. When at destination db, we have instantiated objects, why not we have some kind of mechanism by which new capture process will start capturing the changes from the least instantiated scn among all instantiated tables ? Is there any other work around than exp/imp when both db (schema) are not sync at source / destination b'coz of failure of capture process. We did face this problem, and could find only one work around of exp/imp of data.
thanx,Thanks Mr SK.
The foll. query gives some kind of confirmation
source DB
SELECT SID, SERIAL#, CAPTURE#,CAPTURE_MESSAGE_NUMBER, ENQUEUE_MESSAGE_NUMBER, APPLY_NAME, APPLY_MESSAGES_SENT FROM V$STREAMS_CAPTURE
target DB
SELECT SID, SERIAL#, APPLY#, STATE,DEQUEUED_MESSAGE_NUMBER, OLDEST_SCN_NUM FROM V$STREAMS_APPLY_READER
One more question :
Is there any maximum limit in no. of DBs involved in Oracle Streams.

Can stream "capture process" skip an archivelog?
DB: 10.2.0.5, on Windows 2003 SP2 32-bits
A stream capture component in our database is stuck reading one the archive log file, and status in the v$streams_capture view is 'CREATING LCR' . It is not moving at all.
I think, the archivelog is corrupted and will guess skipping from reading the log can help??
Any idea?Find the transaction identifier in the trace file; for example in this trace the transaction is '0x000a.008.00019347'
Convert it from hex to decimal; in this example '0x000a.008.00019347' will be '10.8.103239'.

Error while invoking ESB process from a BPEL process
Hi all
We have a requirement to call an ESB process from a BPEL process. We are using an adapter wth the ESB's WSDL url. After deploying the BPEL process, the registered ESB is getting called for most values while suddenly some values return the followign error
*"exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection reset"*
The catch here is, if we re-run the process with the same values again, the ESB is called successfully! How is it possible for a process to error out and run normally for the same inputs ?
What could be the possible fix for this? I am thankful for any inputs on this.
VijayHi Vijay,
This is a bug and you can refer the metalink note:
"Applying Patch 7445876 Results in Error "java.lang.NullPointerException". [ID 942575.1]" for reference.
Also you can refer the following link:
"http://puchaanirudh.blogspot.com/2008/12/exception-on-jaxrpc-invoke-http.html" also.
Thanks,
Vishwanath. -
Excise invoice capture process
Hi,
I want to know about excise invoice capture process for depot plant which t. cod eis use for depot plant how to do the part1 and part2 and also reversal process for the same.
also what is diff. between excis einvoice capture process for depot and non depot plant.
regards,
zafarHi Zafar,
There are no part 1 and part 2 in RG23D for depot scenario. You can update RG23D at the time of MIGO or J1IG "Capture excise invoice for depot".
For cancelling you can use the same transaction. And to send the goods out from Depot plant use T-code J1IJ for updating RG23D.
Rest process remains the same Extraction J2I5 and print through J2I6.

How to reset an failed asynchron abap-process in a process-chain?
Hi specialists,
I've got a process-chain which triggers (as one of its steps) an abap-program.
The program should run asychroniously, so the process-chain waits until the programm reports its ending.
When the abap-program fails/crashes/dumps, then the endings is never reported and the process-chain gets stuck.
If I try to re-run that process-chain, it fails again with the message "Variant XYZ still executing from previous run".
What I already found so far is the following note:
The process chain management will not know if your program terminates!
Thus if you re-start the chain, this will also terminate, because the old run would not have finished yet. To avoid this, you need to manually set the process in the chain log view in the process monitor to terminate before you start again.
My problem: I cannot find any possibility to set the process to "terminate" in the chain's log view.
Could you please gimme a hint where I can find that option?
Best regards,
MarcoHi,
You can remove the process chain from scheduling before staring the process chain again.
Also can edit the entries in RSPROCESSLOG table before running the process chain.
Alternatively you can create a custom ABAP process type which handles the success as well as fail cases.
Refer : [How To- Trigger subsequent processes in a Process Chain based on the Success or Failure of ABAP program|/people/balaji.venugopal/blog/2009/04/07/how-to-trigger-subsequent-processes-in-a-process-chain-based-on-the-success-or-failure-of-abap-program]
Hope this helps,
Regards,

LABVIEW.LIB was not called from a LabVIEW process
Hi All,
I've inherited LV code that calls a CIN node to access a motor controller. I'd like to compile this code to a .NET DLL, but receive the following error when calling it from an external source:
I've read the knowledgebase article explaining the problem from here, as well as the following support questions:
http://forums.ni.com/t5/LabVIEW/Labview-lib-was-not-called-from-a-labview-process/m-p/232548
http://forums.ni.com/t5/LabVIEW/Problem-with-lsb-LABVIEW-LIB-was-not-called-from-a-LabVIEW/m-p/48809...
http://forums.ni.com/t5/LabVIEW/Labview-lib-was-not-calld-from-a-labview-process/m-p/718427
http://forums.ni.com/t5/LabVIEW/Building-a-LabVIEW-DLL-with-VIs-that-use-CINs/m-p/632817
The conclusion seems to be recompiling is the answer. I've tried recompiling the original CIN vi within LV with no success. Do they mean to recompile the original C code against the newer labview.lib (sorry, I'm not all that familiar with how the CIN nodes work)? Any suggestions would be awesome. Thanks.
-JoeYou can't make use of LabVIEW manager functions in non-LabVIEW based processes. Basically unless the C code is for a CIN or DLL that is to be called by LabVIEW (inside the development system or a LabVIEW built application), any function pulled in from labview.lib is not available. LabVIEW.lib is an import library that does not implement any functions but simply imports them from the LabVIEW kernel, either the LabVIEW development system or the LabVIEW runtime DLL. And no you can't just link in the LabVIEW runtime DLL into your .Net application. This DLL needs to be started up and initialized in very specific ways, that only LabVIEW itself knows about when building an application.
Basically if you want to recompile the code (yes in C/C++) for use in a non-LabVIEW application, you also have to remove all the link libraries from the LAbVIEW cintools directory, and replace any use of functions now unavailable (link error: unavailable external reference) with other similar functionality from your C runtime library. Or implement those functions yourself using C runtime library calls.
Another possibility could be to actually create a LabVIEW executable that exports the functionality as ActiveX Server. Or in LabVIEW 2010 you could also select to create a .Net Interop Assembly from inside the LabVIEW project.
