DGCserver renewing lost refs

Hey all,
We're running WLS 4.5.1sp5 on solaris 2.7.
After some time, we start to see our execute queue length start to
increase dramatically. At the same time we start to see the following
messages:
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 677
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 678
Fri Jul 06 12:03:54 EDT 2001: <DGCserver> tried to renew lease for
lost ref: 692
This happens a lot and soon after start up on the new hosting
environment but hardly ever on the old hosting environment and never on
the development machines. The boxes are all the same... why would this
happen?
Any insights would be appreciated.

Chad,
These messages indicate that a server got a message to renew a DGC lease for
a reference it had already collected. This means that the lease renewal
messages aren't being received and/or processed in a timely manner. Since
you mention that the execute queue length is quite long that is likely the
cause of the problem.
To diagnose that problem I would recommend taking a thread dump from the
server VM. Look at what the threads are doing. Are they blocked trying to
obtain some resource or doing some other operation that is preventing them
from proceeding?
Cheers!

DGCServer - tried to renew lease for lost ref: 509

Recently we have been getting ALOTof messages in our server log file of the
form:
Fri Jul 14 10:08:19 PDT 2000: <DGCserver> tried to renew lease for lost
ref: 509
We use RMI for java client to server communcation and are using Weblogic
4.5.1 SP 8
with nativeIO enabled.
What could be causing these messages?
Thanks!
Rick

Thanks! I still have one problem, the lease renewal messages for lost
references never seem
to end for the specific reference. I have a weblogic.log file with hundreds
of those messages for
each lost reference (and still going). It seems that it is not giving
up... any ideas?

Normally, I would ask a customer in the situation to provide more about
their application. But, since I know a lot about how your application is
architected, I would guess the people are shutting down their browserswhile
your applet still running. The applet is not closing the socket cleanly
with Weblogic. The distributed garbage collector, which keeps track ofall
of the distributed objects, is trying to renew a lease for that object.It
cannot locate it and will eventually give up on it.

DGCServer messages in log... "tried to renew lease"

Hi,
 I'm running three WL 4.5.2 servers clustered, JDK1.1.7b on Solaris 2.6.
 Normally the cluster runs just fine, but now I'm beginning to see the
 following message in all three servers:
 <DGCserver> tried to renew lease for lost ref: nnn
 Usually they come in small bursts of about 5 or 10 messages that are the
 same, except the "ref"s keep increasing. I'm guessing it has to do something
 with the in-memory replication of sessions (which I'm using).
 Any ideas? I tried restarting the servers but after a little while the
 messages started again.
 Thanks,
 Matias


One common symptom for this (Bad Status Exception) has been long gc. If gc
 takes more 30 seconds then you will start seeing these errors. To assertain
 this, you could turn on weblogic.debug.cluster=1 and if you see a message "Timed
 out server" in the log then you should tune your server.
 Please use latest service packs.
 thanks

Reference is lost when updating selection option

Hi all,
In my application, I need to update selection screen according to user input, like update dropdown list. Therefore, I write my coding at view event WDDOMODIFYVIEW to ensure my method UpdateScreen is called at every roundtrip. Everything runs OK except when I click sign/option and choose any sign of selection option following dump occurs:
The following error text was processed in the system ICX : Access via 'NULL' object reference not possible.
The error occurred on the application server pwdf4646_ICX_12 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: IF_WD_CONTEXT_ELEMENT~SET_ATTRIBUTE of program CL_WDR_CONTEXT_ELEMENT========CP
Method: SET_SIGN of program CL_WDR_SELECT_OPTIONS=========CP
Method: ON_SIGN_OPTION_LEAVE of program CL_WDR_SELECT_OPTIONS=========CP
Method: ONACTIONON_ENTRY_SELECTED of program /1BCWDY/ALMK9CLI947HVDFYUZV5==CP
Method: ONACTIONON_ENTRY_SELECTED of program /1BCWDY/ALMK9CLI947HVDFYUZV5==CP
Method: IF_WDR_VIEW_DELEGATE~WD_INVOKE_EVENT_HANDLER of program /1BCWDY/ALMK9CLI947HVDFYUZV5==CP
Method: INVOKE_EVENTHANDLER of program CL_WDR_DELEGATING_VIEW========CP
Method: IF_WDR_ACTION~FIRE of program CL_WDR_ACTION=================CP
Method: DO_HANDLE_ACTION_EVENT of program CL_WDR_WINDOW_PHASE_MODEL=====CP
Method: PROCESS_REQUEST of program CL_WDR_WINDOW_PHASE_MODEL=====CP
It losts ref since I call if_wd_select_options~upd_selection_field before choosing sign. If user clicks sign/option, there's no need to update selection screen because no user input changes. But how can I judge this?

Please let me comment more since no attachment can be uploaded. Following are key steps I do:
1) Build selection screen of two select options with this:
lr_range = lr_selopt->create_range_table( i_typename = 'CRMT_PROCESS_TYPE' ).
lr_selopt->add_selection_field(
    i_id                       = 'ACT_PROCTYPE'
    it_result                  = lr_range
    i_description              = 'Transaction Type'
lr_range = lr_selopt->create_range_table( i_typename = 'CRMT_ACTIVITY_CATEGORY' ).
lr_selopt->add_selection_field(
    i_id                          = 'ACT_CAT'
    it_result                     = lr_range
    i_value_help_structure_field = 'CATEGORY'
2) At method WDDOMODIFYVIEW, I update the description for example:
lr_range = lr_selopt->create_range_table( i_typename = 'CRMT_PROCESS_TYPE' ).
lr_selopt->upd_selection_field(
    i_id                       = 'ACT_PROCTYPE'
    it_result                  = lr_range
    i_description              = 'New Transaction Type'
Then, if I click the sign button before select option and choose a sign, it gets dump.
I know the calling of upd_selection_field interferes something, but I have to update screen in order to complying with user input.

Errors encountered during perfromance testing

While doing some stress testing on our WLS server we kept seeing the
following errors:
1) NullPointerException on NTSocketMuxer, error log follows:
Tue Feb 22 05:08:28 EST 2000:<E> <NTSockMux> failure in processSockets()
loop: GetData: fd=16764 numBytes=23
Tue Feb 22 05:08:28 EST 2000:<E> <NTSockMux>
java.lang.NullPointerException: null native pointer - socket was closed
at weblogic.socket.NTSocketMuxer.initiateIO(Native Method)
at weblogic.socket.NTSocketMuxer.processSockets(NTSocketMuxer.java,
Compiled Code)
at
weblogic.socket.SocketReaderRequest.execute(SocketReaderRequest.java:19)
at weblogic.t3.srvr.ExecuteThread.run(ExecuteThread.java, Compiled
Code)
This error doesn't seem to have any immediate impact, although it can't
be a good thing and it seems to happen even at times when we are not
doing stress testing. Also, it is very frequent that we see the above
messages. We are running WLS 4.51 w/ Service Pack 5. I am wondering if
this is a problem w/ Service Pack 5 since I don't see this on another
machine running WLS 4.51 with Service Pack 4. Both are using JDK 1.2.2.
2) Connection Rejected, error log follows:
Tue Feb 22 07:08:16 EST 2000:<W> <ListenThread> Connection rejected:
Login timed out after 15000 msec. The socket came from
[host=207.17.47.141,port=11929,localport=443] See property
weblogic.login.readTimeoutMillis.
I know how to adjust this for this one. My questions on this are:
If I set my readTimeoutMillisSSL (SSL in this case) from 15000 to 30000
what does this exactly mean. Does this mean that instead of allowing a
max 15 seconds for a connection to be established, now I am allowing 30
seconds? Also, is this only for the initial connection establishment (ie
user login), or does this parameter effect other aspects of the
connection later on? What negative side effects would I encounter if I
set this to 60000 (1 minute)?
Finally, what can I do so that a connection does not take over 15
seconds to establish? Note this is not the norm, just happens more often
during stress testing.

Hi Kim,
Thanks for the response, but which problem in particular did you solve, I've
listed a couple here.

How is Opportunity Win Rate calculated

Metrics are not always so easy to figure out.
So is there a list / document that explains how these fields are calculated?
Specifiically how is the Opportunity Win Rate calculated?
Thanks.

Win Rate = ((# of wins) / (# of wins + # of losses))
I believe Win = Closed/Won and Lose = Closed/Lost
Refer Doc ID 565203.1 in metalink for more details.

No role for business system defined in SXMS_CONF_ITEMS

Hi Experts.
I have the following problem. We were set up the XI in our company and now we are trying to configure and run it propertly. We had some problems so far and now there is the next one: I configured the simple scenario FILE-XI-FILE but it doesn't work :(. Every step from the scenario was completed successfully (after some problems) but when I have started runtime Workbench (RWB) in order to monitor the functionality of XI and I choosed Component Monitoring | Components | Integration Server | Integration Engine GPI I see that I have an error in Self-Test Status | Are roles in SXML_CONF_ITEMS and SLD consistent? In detail it's No role for business system defined in SXMS_CONF_ITEMS. My business and technical systems look to be well configured but now I'm hopeless because I can't find nothing more specific about SXMS_CONF_ITEMS table. I tried some notes and threads from the forum but nothing helped me after all. So please help if someone has an experience with something similar. Any help will be appreciated. Thanks
Ondrej

Hi,
The role of a business system is defined centrally in the SLD. However, you can overwrite this setting locally in the table SXMS_CONF_ITEMS.
This test checks whether the role descriptions are consistent. If not, the locally defined role is used at runtime.
Check in transaction SXMB_ADM -> integration engine configuration a parameter (Corresponding Integ. Server) if all parameters are correct n not lost.

WARNING to ALL

Yesterday I had a 3 second brown out and the Library crashed . Lightroon said the library was corrupted and to install a new Library . I lost all mY pictures in the Library. Lesson learned.
Going to buy a battery back up today.
Good Luck,

Personal datasets are getting larger and larger. A simply hiccough can wipe out unbelievable amount of data compare with only a few years ago.
Missing a few MBs of data was sad, losing a few GBs was bad. Losing a TB of data is an unrecoverable disaster.
Back up your stuff. If you are serious about your photography (i.e., make a living from it), you can hire a service or sign up for Amazon S3 service (or something) and store a copy of the backup offline.
Me? I just backup my entire home directory to a Firewire drive that is rarely turned on and is only used for this purpose. I still want to get a SAN that backups upon demand.
This all being said, could you not have grabbed the last library file that Lightroom backs up occasionally? You might have lost refs to imports and changes since it was last saved, but it is better than nothing.

Service Contract Cancellation - WV

I am not able to cancel the service contract.
Am getting this message " The next possible cancellation date is 04.05.2013"
how to resolve it?

I don't have much idea on this.
Use Tcode VORB - Define Reference Sales Document Types for Service Contract - WV, say, MK.
Then TCode VOV8 - Sales doc type Service Contract - WV, check the Contract profile, say 0002
Now TCode VOVR - check Contract prof. 0002 and under Cancellation proced take note of Assignment cancellation procedure/cancellation rule, say, 0002 Cancel w/ 3 months notice and yr renewal.
Now, you can flow following path in SPRO:
IMG - SD - Sales - Contracts - Contract Data - Control Cancellation
Then Check the in TCode VOVN - check Assign Cancellation Rules And Cancellation Procedures
Cnacellation Procedure
Cancellation Rule
Decs
0002
0001
Cancel. up to 1 wk after contract start
0002
0003
Cancel w/ 3 months notice and yr renewal
Now refer Tcode VOVL for cancellation rule. This incidates level at which a contract may be initialted for termination
Cancellat.rule
0003 Cancel w/ 3 months notice and yr renewal
Canc.date
08 Contract Start Date + Contract Validity Period
Notice
3-
Canc.unit
3 Month
Canc.period
1
Period unit
4 Year
Therfore for your error,
The next possible cancellation date is 04.05.2013
cancellation rule (VOVL) & Contract validity period plays a vital role.
For further reference/understanding try and refer following link from SAP Help how
- [ Data on cancellation in Contract processing |http://help.sap.com/saphelp_45b/helpdata/en/b4/613275e24bd111950d0060b03c6b76/content.htm] works.

Tried to renew lease for lost reference

Hi
Oracle sessions get stuck on parsing all sessions accessing the same object wait
on "library cache pin".
We found one session coming from jdbc client waiting on "SQLNET message from client"
and holding all the rest sessions.
When we kill this session the problem resolves.
Following the port holding session with netstat, lsof and so on back to the jdbc
client side on different machine we only see error message connected to the same
port saying "tried to renew lease for lost reference". Our assumption is that
oracle lost connection with the client while locking a DB object when was doing
parsing and thus locked all sessions that wanted to access same object.
Did anybody encounter the same problem? How was resolved?
Thanks.

In testing the cluster failover capability, I disconnected the
network cable from one of the servers I was running in a cluster.
The system failed over properly. When I reattached the network
cable, the system added the server back into the cluster. However,
I continue to get the following message:
Tue Dec 12 17:34:51 GMT 2000: <DGCserver> tried to renew lease
for 1 lost references
(s).
What is the cause of this message? What needs to be done to clean
up the cluster?Rich,
This message is printed when one WebLogic kernel tries to renew a lease for
an remote object from another WebLogic which has already been collected. It
makes sense that this might happen in the failure scenario you describe.
When the network is disconnected DGC lease renewals can't be sent and the
kernel exporting the object may therefore believe that the object is no
longer in use and collect it. When the network is re-established the remote
objects may be gone.
However the fact that you are seeing this message printed repeatedly is
troubling. You may want to contact [email protected] with the
description you provided here along with the following additional
information.
Are you seeing this message on the client or server? If on the server is it
on the server that was disconnected or on one of the other servers? What
version (including service packs) of WebLogic are you running?

I seem to have lost the appointments in my Ipad2 calendar for the months of July, August and September. I need to refer back to them, and there are only a few appointments reflected. What can I do to recover this info?

Are they still on your pc's calendar? If so, connect the ipad, go to 'info' scroll down to the calendar and change the setting of 'do not sync items older than....' as far back as you need it

Itunes match renewed and lost all my music

My itunes subscription automatically renewed on 10/6/13 and I have a reciept for the transaction. Now all my music is missing. This is really ******* me off. I have so much music it will take forever to get it all back on my computer and then into the cloud. Does anyone have suggestions on how to find my music in the could again? Yes, I have itunes match turned on.

Have you done a search of your hard drive to make sure the purchases are actually gone and haven't just been erased from the iTunes library database? iTunes Music Store: Finding missing music and video downloads
If they are completely gone, if you have an iPod that still has any of your purchases on it you'll find details in this article on how to transfer them to the computer: iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
Failing this, you could try contacting iTunes Store Customer Service and you might be able to persuade them to sanction a second free download. There have been occasional reports in the iTunes forum of this happening, however just be aware that they are not under any obligation to do so. The official policy on music/media purchases is that you only get one download and it's up to you to maintain a backup against loss: iTunes Store: Purchased content can be downloaded only once
If you click on this link it'll take you to the support/contact page, from there click on Music Purchases then the Lost or Missing Items option, from there click on "Email Us": Customer Service - iTunes Store Support

REFS, lost hard disk space after Windows defragmentation

Hi,
first some short information about the Server.
Windows Server 2012 Datacenter
OS disk = 60 GB SSD
Physical raid Controller: Areca ARC-1261
Raid = Level 6
Used Disks = 11 x 2TB + 1 hot spare
File system = REFS
Usable space = 16,3 TB
Real used space (what the tools and folder properties counted) = 14,0 TB
Used space (what i see in the computer overview) = 15,4 TB
Unknown space what I could see with disk scan tool (or the tools calculated) = 1,4 TB
So here what you could quickly see that i've got a "little" problem with wasted/unknown space....
How the Problem originated:
The system drive is a SSD, after running this Server about 150 days and unnecessary little Windows problems i remembered the garbage collector for SSD (TRIM).
So i wanted to schedule with "Defragment and Optimize Drives" an automatic job for cleaning the drive.
My problem was, that I couldn't deselect the big raid volume, but i gave it a try an scheduled weekly the optimization.
Next day i got some alerts "low disk space warnings", i've lost about 1 TB of disk space but could not explain how I could lost this amount of space.
After starting a resizing of the raid, i counted with file property the real used space and could not explain the shown size in the overview.
What I've tried to fix this problem:
First of all, a lot of google....
Shadow copy: checked, fully cleaned, disabled = nothing just a few GB.
Backup: checked, fully cleaned, disabled = nothing, but ran under an extra disk but... could never know what's wrong
Folder options: enabled this far that i could see system protected files and default hidden
Safe boot = tried a safe boot (some solutions for different user in the web) = nothing could not see more or less
O & O Defrag (latest server edition) = didn't support REFS
last of it, new clean installation of windows
My Questions:
Is defragmentation on refs possible/useful or is it just an bug with that "Defragment and Optimize Drives" tool?
Are the any information's about fixing troubles on REFS or commands on PS oder cmd? (could not find anything on google)
I've got some books for WS2012 and e-books but there are no helpful information's about REFS.
I know this is a big text block, but i wanted to show you detailed the problem and my attempts to solve this problem.
I hope you could help me or show me new ways to solve this problem.
Tanks in future....!

ReFS formats by default to 64KB block sizes (shows up in Disk Management as "Allocation Unit Size" when you go try formatting).
NTFS formats by default to 4 KB block sizes and up to 64KB.
If you have 1 file that is 4KB in size, and you use ReFS (default block size), it's going to occupy the entire 64KB. That is true of NTFS if you choose to format in 64KB (required for SQL and Hyper-V VHD's and VHDX's).
If your files are smaller than 64K, then stick with NTFS.
Yong Rhee [MSFT]
That is true for the defaults for ReFS but its possible to use a smaller allocation size using the options. Unfortunately most never think to do that.
