E1 pri troubleshooting tools/guides

Hello!
Does anybody have information about troubleshooting build-in E1 interfaces in BE3K (Layer1-Layer3)?
I found:
Troubleshooting Using MCS 7890-C1 LEDs (http://www.cisco.com/en/US/docs/voice_ip_comm/cucmbe3k/8_6_3/system/BE3K_BK_C30C50F6_00_cucm-be3000-admin-guide_chapter_0101111.html#BE3K_RF_MFEF356B_00)
Gateway Loopback (http://www.cisco.com/en/US/docs/voice_ip_comm/cucmbe3k/8_6_3/system/BE3K_BK_C30C50F6_00_cucm-be3000-admin-guide_chapter_010111.html#BE3K_RF_G5E7F42E_00)
And that is all.

Hi Navin,
Thanks for answer. We already opened case in TAC.
But the main thing that with any problem... big or small... customer should go to TAC. Because it has only LEDs: green or red... No tools, no docs about reading diagnostic logs.
About my problem... It seems that cause is on Telco side... but before we understand that five people from Cisco all around the World worked with my case. Two of them are in developers team, one of them - CCIE. Do you thing that it is right thing? Give information to customers and they will solve their problems without assistance.

Oracle Support ORA-4031 Troubleshooting Tool problem - FILE VALIDATION FAIL

Hi,
Having problem while trying to use ORA-4031 Troubleshooting Tool on the Oracle Support site.
I believe I upload all files correctly: db alert log, 4031 trace file and AWR report (HTML), answered YES to the question.
But, get this error:
"FILE VALIDATION FAILED: Fatal Error: missing 4031 information in the trace file. ..."

My question here is not abuot ORA-4031 error and how to troubleshoot it, but about the error (FILE VALIDATION FAILED) that I receive in ORA-4031 Trobleshooting Tool on the Oracle Support web site. We do manuall analyses and troubleshooting as well, but would be nice if the tool works as well.Have you followed all the steps in (How to use the ORA-4031 Troubleshooting Tool on MOS [ID 1381442.1])? If yes, then I believe you need to log a SR for this issue as none of us maintain this tool, and you need someone from Oracle (development team who maintain it internally) to verify why you are getting that error when uploading the files.

Where do I find the JavaScript Tools Guide

I’m fairly new to Adobe scripting. I just downloaded the Photoshop 2014 CC JavaScript Reference,
and in describing ExtendScript’s features, it includes the line,
For details of these and additional features, see the JavaScript Tools Guide,
which it says is installed with Adobe CC at
C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit CC 2014\SDK.
It wasn’t there — there’s no such folder on my system. The Javascript Reference goes on to say,
The latest versions of this document and of the ExtendScript Tookit,
can also be downloaded from Adobe Developer Center,
http://www.adobe.com/devnet/.
I followed the above link to the Developer Center, and I couldn’t find it there either.
Where can I find a copy of the latest JavaScript Tools Guide?

Install right click tool and client troubleshooting tools.

Hi Everyone,
I need some information, I heave 2012 native mode environment with MacAfee firewall. But I need to install rite click tool and client troubleshoot tools. It is possible or
not, if yes Please give me the detailed Information.
Thanks in advance.

The fact that you're running ConfigMgr 2012 in HTTPS and have a McAfee firewall running, has nothing to do with the installation of right-click tools. If you have the permissions to install the right-click tools on a device, with the ConfigMgr console, you're
good to go.

JavaScript Tools Guide CS6 PDF

I've found that the JavaScript Tools Guide CS6 PDF is not available for download from the Adobe website. It is only available as part of the ExtendScript Toolkit CS6 (ESTK 3.8).
ESTK 3.8 is not available for download from the Adobe website either, but is included in all Adobe CS6 products.
If you have an Adobe CS6 product installed on Windows, the JavaScript Tools Guide CS6 PDF can be found here: C:\Program Files (x86)\Adobe\Adobe Utilities - CS6\ExtendScript Toolkit CS6\SDK\JavaScript Tools Guide CS6.pdf

Thanks Todd, so posting the actual PDF documents themselves would not be allowed then? I ask only because the JavaScript Tools Guide CC.pdf does not have a link online. Search results return only for the JavaScript Tools Guide CS5.pdf

Updated Adustment Tool Guide to cover 1.5.2

I have updated my Aperture Adustment Tool Guide to cover the new tools in 1.5.2 - I apologize for the delay for anyone that was anticipating it.
As always, it's a free download and I ask for donations if you find it of use:
http://InsideAperture.com/Site/AdjustmentToolGuide.html
Besides simply covering the new tools in addition to the old, it has a revamped Exposure section and also a visual walkthrough of the Edge Sharpen process Apple recommends that I hope is a little more illuminating than the default documentation or online guide.

Excellent! I look forward to it. Note that the text-link works fine, but the icon-link doesn't (the filename it's attached to lacks the "-1.5.2" before the file extension).

Rectangular Grid Tool - Guide, Anchor, but NO Intersect?

When using the Rectangular Grid Tool I am starting from the upper edge of the artboard and when moving along the edge I see green indicators stating "Guide" when I am somewhere on the path, and "Anchor" when I am at the edge, "0,0" for instance.
However, I am trying to follow along with a video tutorial, and in the tutorial it shows the same thing EXCEPT that there is AN "Intersect" value in green in the tutorial. The demonstrator verbally mentions the importance of achieving this "Intersect" value several times. So I am wondering why I am not seeing it.
The demonstrator mentions making sure that I have "Smart Guides" turned on, and I DO.
In the video when the demonstrator is hovering over the guide lines with the grid tool it shows two values "PAGE" and "INTERSECT".
On my local machine when I am hovering over the same guide lines with the grid tool it shows two values "GUIDE" and "ANCHOR".
I have looked at the preferences when grid tool is selected and played around with different settings. I have also played around with different snap to settings from main menu, and nothing.
What am I missing?
Here are two images showing what it looks like in the video tutorial, and what I am seeing locally on my machine when trying to duplicate this myself.
VIDEO TUTORIAL SCREENSHOT:
LOCAL MACHINE SCREENSHOT:
Thank you for looking!

The grid of guides in the tutorial screenshot shows no guides along the perimeter of the artboard, so there is no anchor point there, just the artboard; the local screenshot has guides on the perimeter, so the label correctly shows an anchor point in the corner. You would need to go to View > Guides > Lock to deselect Lock so that you can select and delete the offending guides. Smart Guides will then show intersect at the corner of the artboard and page anywhere else along the edge.
Intersect appears where two paths cross without an anchor point.

SALT Configuration Tool - Guide document

Hello
Is there some guide to use SALT configuration tool, I have the following issue :
I already configured with the discovery feature some Tuxedo services and are working ok invoking them as a WS, but now I did the same to add one more service and the discovery feature could not discover the service I reviewed everything, and I could not find what is wrong.
I am using FML32 in all cases.
Something to consider:
-that sometimes I got a message in the ulog, but is not a catalog message is jus "cannot open file".
Maybe there is a Document Guide to use this tool? or somthing like that ,
Thank you in advanced for your help
BR
Ramiro.

Ramiro,
the "cannot open file" message is a bug, harmless you can ignore it.
The configuration tool is self-documented, actually, in the main page you can click on the sentences to expand the functions available in the tool. If the information you are looking for is not in there let us know here.
Regarding your issue, for service discovery to work the service has to be called, make sure that it is the case. If you have done that and still don't see a new service after refreshing the page (F5), it's possibly because it's already there... If the service is the same Tuxedo service and payload, the discovery feature will not create a new entry.
Let us know how it goes.
Regards,
Maurice

Turn Off Pen Tool Guide Line (Rubber Band) - Illustrator CC 2014

Working in Illustrator CC 2014. There is a guide line that follows the pen tool as I create my paths and shapes. I don't remember this from earlier versions of AI and I find it very distracting especially when creating curves,changing directions or once I've finished drawing a stroke. Does anyone know how to turn this feature off?
UPDATE:
If you want to turn this feature off here's how...

Me too, I put up with it for like a month. So helpful. Thanks.

Aperture Will Not Open - Aperture Troubleshooting Basics Guide Does Not Hel

I cannot get Aperture to open and I have gone through all of the steps listed in "Aperture: Troubleshooting Basics". I have tried all of the suggestions including deinsatalling and reinstalling Aperture. Nothing works.

How-to: Using Bonjour Browser as a troubleshooting tool

AirPort Extreme uses Bonjour (http://www.apple.com/macosx/features/bonjour/) to facilitate features like disk sharing and printing. You can use a Bonjour browser to see what features are active on your network.
How does this help?
Many questons on the forum are similar to 'Where's my shared disk/iTunes/printer/airport?' A Bonjour browser can tell you if your disk/iTunes/printer/airport is present in your network. If the feature is not present focus on the device/feature. If the feature is present focus on your client computer.
1) Download a Bonjour browser, e.g. I use this browser: 'Bonjour Browser' (http://www.tildesoft.com/Programs.html)
2) Install and run Bonjour Browser
3) You should see a hierarchy of features under 'local'. There maybe other domains in addition to local.
Here's some examples of Bonjour-advertised features:
Shared disks appear under 'adisk.tcp.' Under this heading you can see all your AirPorts with the disks you nominated for sharing, with IP addresses.
The base station itself is under 'airport.tcp.' Under this entry are all the base stations you have (b/g and n, AirPort Express etc ...)
The 'AirTunes' entry tells you which IP address is your AirTunes/AirPort Express device.
You can also see any file sharing, SSH, iTunes music sharing etc .. that may be offered by your client computers. I see my IP printer under 'Printer PDL Data Stream).
Hope this helps your troubleshooting.

Hi gino,
Select -
where text CP 'Manufacturer' is right answer. If you get error on that statment, you would probably check the field that is used in where clause.
or try the following statement. Hope this will helps.
select -
where text = '%manufacturer%'.
I think it will then become a performance issue. Explain it clearly that what exactly you want and where is this being used.
Do you want some thing like search help? Example: customer number search from any customer field. If so try to create a search help and add the same to your custom field.

[Forum FAQ] Troubleshooting Network File Copy Slowness

1. Introduction
The Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows is known as Microsoft SMB Protocol. The set of message packets that defines a particular version of the protocol is called a dialect. The Common
Internet File System (CIFS) Protocol is a dialect of SMB. Both SMB and CIFS are also available on VMS, several versions of Unix, and other operating systems.

SMB Versions and Negotiated Versions
- Thanks for the
Jose Barreto's Blog
There are several different versions of SMB used by Windows operating systems:
CIFS – The ancient version of SMB that was part of Microsoft Windows NT 4.0 in 1996. SMB1 supersedes this version.
SMB 1.0 (or SMB1) – The version used in Windows 2000, Windows XP, Windows Server 2003 and Windows Server 2003 R2
SMB 2.0 (technically SMB2 version 2.002) – The version used in Windows Vista (SP1 or later) and Windows Server 2008 (or any SP)
SMB 2.1 ((technically SMB2 version 2.1) – The version used in Windows 7 (or any SP) and Windows Server 2008 R2 (or any SP)
SMB 3.0 (or SMB3) – The version used in Windows 8 and Windows Server 2012
SMB 3.02 (or SMB3) – The version used in Windows 8.1 and Windows Server 2012 R2
Windows NT is no longer supported, so CIFS is definitely out. Windows Server 2003 R2 with a current service pack is under Extended Support, so SMB1 is still around for a little while. SMB 2.x in Windows Server 2008 and Windows Server 2008
R2 are under Mainstream Support until 2015. You can find the most current information on the
support lifecycle page for Windows Server. The information is subject to the
Microsoft Policy Disclaimer and Change Notice. You can use the support pages to also find support policy information for Windows
XP, Windows Vista, Windows 7 and Windows 8.
In Windows 8.1 and Windows Server 2012 R2, we introduced the option to completely disable CIFS/SMB1 support, including the actual removal of the related binaries. While this is not the default configuration, we recommend disabling this older
version of the protocol in scenarios where it’s not useful, like Hyper-V over SMB. You can find details about this new option in item 7 of this blog post:
What’s new in SMB PowerShell in Windows Server 2012 R2.
Negotiated Versions
Here’s a table to help you understand what version you will end up using, depending on what Windows version is running as the SMB client and what version of Windows is running as the SMB server:
OS
Windows 8.1 WS 2012 R2
Windows 8 WS 2012
Windows 7 WS 2008 R2
Windows Vista WS 2008
Previous versions
Windows 8.1 WS 2012 R2

SMB 1.0
SMB 1.0
SMB 1.0
SMB 1.0
* WS = Windows Server
1.2 Check, Enable and Disable SMB Versions in Windows operating systems
In Windows 8 or Windows Server 2012 and later, there is a new PowerShell cmdlet that can easily tell you what version of SMB the client has negotiated with the File Server. You simply access a remote file server (or create a new mapping to it) and use Get-SmbConnection.
To enable and disable SMBv1, SMBv2, and SMBv3 in Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012, please follow the steps in the article below.
Warning: We do not recommend that you disable SMBv2 or SMBv3. Disable SMBv2 or SMBv3 only as a temporary troubleshooting measure. Do not leave SMBv2 or SMBv3 disabled.

1.4 Related Registry Keys
HKLM\SYSTEM\CurrentControlSet\Services\MrxSmb\Parameters\
DeferredOpensEnabled – Indicates whether the Redirector can defer opens for certain cases where the file does not really need to be opened, such as for certain delete requests and adjusting file attributes.
This defaults to true and is stored in the Redirector variable MRxSmbDeferredOpensEnabled.
OplocksDisabled – Whether the Redirector should not request oplocks, this defaults to false (the Redirector will request oplocks) and is stored in the variable MrxSmbOplocksDisabled.
CscEnabled – Whether Client Side Caching is enabled. This value defaults to true and stored in MRxSmbIsCscEnabled. It is used to determine whether to execute CSC operations when called. If CSC is enabled,
several other parameters controlling CSC behavior are checked, such as CscEnabledDCON, CscEnableTransitionByDefault, and CscEnableAutoDial. CSC will be discussed in depth in its own module, so will be only mentioned in this module when it is necessary to understanding
the operation of the Redirector.
DisableShadowLoopback – Whether to disable the behavior of the Redirector getting a handle to loopback opens (opens on the same machine) so that it can shortcut the network path to the resource and
just access local files locally. Shadow opens are enabled by default, and this registry value can be used to turn them off. It is stored in the global Redirector variable RxSmbDisableShadowLoopback.
IgnoreBindingOrder – Controls whether the Redirector should use the binding order specified in the registry and controlled by the Network Connections UI, or ignore this order when choosing a transport
provider to provide a connection to the server. By default the Redirector will ignore the binding order and can use any transport. The results of this setting are stored in the variable MRxSmbObeyBindingOrder.
HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters\
Security Signature settings – The RequireSecuritySignature setting is stored in MRxSmbSecuritySignaturesRequired, EnableSecuritySignature in MRxSmbSecuritySignaturesEnabled, RequireExtendedSignature
in MRxSmbExtendedSignaturesRequired, and EnableExtendedSignature in MRxSmbExtendedSignaturesEnabled. Note that the Extended Security Signatures assume the regular security signatures are enabled, so those settings are adjusted if necessary based on the extended
settings. If extended signatures are required, regular signatures have to be required.
EnablePlainTextPassword – Support for using plain text passwords can be turned on using this key. They are disabled by default.
OffLineFileTimeoutIntervalInSeconds – Used to set the expiration time for timing out an Exchange (discussed later) when the exchange is accessing an offline file. This value defaults to 1000 seconds,
but can be changed in the registry and is stored in the global Redirector variable OffLineFileTimeoutInterval
SessTimeout – This is the amount of time the client waits for the server to respond to an outstanding request. The default value is 60 seconds (Windows Vista). When the client does not receive the
response to a request before the Request Expiration Timer expires, it will reset the connection because the operation is considered blocked. In Windows 8, the request expiration timer for the SMB 2 Negotiate is set to a smaller value, typically under 20 seconds,
so that if a node of a continuously available (CA) cluster server is not responding, the SMB 3.0 client can expedite failover to the other node.
ExtendedSessTimeout – Stored in the ExtendedSessTimeoutInterval variable, this value is used to extend the timeout on exchanges for servers that require an extended session timeout as listed in the
ServersWithExtendedSessTimeout key. These are third party servers that handle SMB sessions with different processes and vary dramatically on the time required to process SMB requests. The default value is 1000 seconds. If the client is running at least Windows
7 and ExtendedSessTimeout is not configured (By Default), the timeout is extended to four times the value of SessTimeout (4 * SessTimeout).
MaxNumOfExchangesForPipelineReadWrite – This value is used to determine the maximum number of write exchanges that can be pipelined to a server. The default is 8 and the value is stored in the variable
MaxNumOfExchangesForPipelineReadWrite.
Win9xSessionRestriction – This value defaults to false, but is used to impose a restriction on Windows 9x clients that they can only have one active non-NULL session with the server at a time. Also,
existing session based connections (VNETROOTS) are scavenged immediately, without a timeout to allow them to be reused.
EnableCachingOnWriteOnlyOpens – This value can cause the Redirector to attempt to open a file that is being opened for write only access in a manner that will enable the Redirector to cache the file
data. If the open fails, the request will revert back to the original requested access. The value of this parameter defaults to false and is stored in the MRxSmbEnableCachingOnWriteOnlyOpens variable.
DisableByteRangeLockingOnReadOnlyFiles – This parameter defaults to false, but if set to true will cause level II oplocks to automatically be upgraded to batch oplocks on read-only files opened for
read only access. It is stored in the variable DisableByteRangeLockingOnReadOnlyFiles.
EnableDownLevelLogOff – False by default, this value controls whether a Logoff SMB will be sent to down-level servers when a session is being closed. If this is false, and the server has not negotiated
to the NT SMB dialect or does not support NT Status codes, the logoff will not be sent because we aren’t sure that server will understand the request. The value is stored in MrxSmbEnableDownLevelLogOff.
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\
ResilientTimeout – This timer is started when the transport connection associated with a resilient handle is lost. It controls the amount of time the server keeps a resilient handle active after the
transport connection to the client is lost. The default value is 300 seconds (Windows 7, Server 2008 R2, 8, Server 2012).
DurableHandleV2TimeoutInSecond – This timer is started when the transport connection associated with a durable handle is lost. It controls the amount of time the server keeps a durable handle active
after the transport connection to the client is lost. The default value is 60 seconds (Windows 8, Windows Server 2012). The maximum value is 300 seconds.
HKLM\SYSTEM\CurrentControlSet\Services\SMBWitness\Parameters\
KeepAliveInterval – This functionality was introduced for SMB 3.0 in Windows 8 and Windows Server 2012. The witness protocol is used to explicitly notify a client of resource changes that have occurred
on a highly available cluster server. This enables faster recovery from unplanned failures, so that the client does not need to wait for TCP timeouts. The default value is 20 minutes (Windows 8, Windows Server 2012).
HKLM\System\CurrentControlSet\Services\SmbDirect\Parameters\
ConnectTimeoutInMs – Establish a connection and complete negotiation. ConnectTimeoutInMs is the deadline for the remote peer to accept the connection request and complete SMB Direct negotiation. Default
is 120 seconds (Windows 8).
AcceptTimeoutInMs – Accept negotiation: The SMB Direct Negotiate request should be received before AcceptTimeoutInMs expires. The servers starts this timer as soon as it accepted the connection. Default
is 5 seconds (Windows 8).
IdleConnectionTimeoutInMs – This timer is per-connection. It is the amount of time the connection can be idle without receiving a message from the remote peer. Before the local peer terminates the
connection, it sends a keep alive request to the remote peer and applies a keep alive timer. Default is Default: 120 seconds (Windows 8).
KeepaliveResponseTimeoutInMs – This attribute is per-connection. It defines the timeout to wait for the peer response for a keep-alive message on an idle RDMA connection. Default is 5 seconds (Windows
8).
CreditGrantTimeoutInMs – This timer is per-connection. It regulates the amount of time that the local peer waits for the remote peer to grant Send credits before disconnecting the connection.
This timer is started when the local peer runs out of Send credits. Default is 5 seconds (Windows 8).

3. How to Troubleshoot
3.1 Troubleshooting Decision Tree
1
Is the slowness occurring in browsing a network shared folder or copying a file, or both?
Browsing, go to 1.1.
Copying, go to 1.2.
Both, go to 1.3.
1.1
Is the target a DFS path or not?
Yes, go to 1.1.1.
No, go to 1.1.2.
1.1.1
Is the client visiting the nearest DFS root server and file server?
Yes, go to 1.1.1.1.
No, go to 1.1.1.2.
1.1.1.1
Browse the corresponding (Non-DFS) UNC path directly. Do you still experience the slowness?
Yes, go to 1.1.1.1.1.
No,
go to 1.1.1.1.2.
1.1.1.1.1
Issue is the particular file server responds to the share folder enumeration requests slowly. Most probably it’s
unrelated to DFS. Follow 1.1.2.
1.1.1.1.2
Issue is that client experiences delay when browsing the DFS path, but no delay is visiting the target file server
directly. Capture Network Monitor trace from the client and study if the DFS path is cracked down.
1.1.1.2
Use dfsutil.exe to clear local domain and referral cache. Then visit the DFS path again and capture Network Monitor
trace from the client to study why the client goes to a wrong file server or DFS root server.
1.1.2
Not a DFS issue. Issue is the particular file server responds to the share folder enumeration requests slowly. “Dir”
the same share folder from Command Prompt. Is it slow?
Yes, go to 1.1.2.1
No, go to 1.1.2.2
1.1.2.1
Check the number of subfolders and files in that share folder. Is the number large?
Yes, go to 1.1.2.1.1
No, go to 1.1.2.1.2
1.1.2.1.1
Try to “dir” a different share folder on the same file server, but with less items. Is it still slow or not?
Yes, go to 1.1.2.1.1.1
No, go to 1.1.2.1.1.2
1.1.2.1.1.1
Probably to be performance issue of the file server. Capture Network Monitor trace from both sides, plus Performance
Monitor on the file server.
1.1.2.1.1.2
Probably to be performance issue of the file server, particularly, of the disk. Capture Network Monitor trace from
both sides, plus Performance Monitor on the file server.
1.1.2.1.2
Same as 1.1.2.1.1.1. Probably to be performance issue of the file server. Capture Network Monitor trace from both
sides, plus Performance Monitor on the file server.
1.1.2.2
Explorer.exe browses the share folder slowly while “dir” does fast. The issue should lie in the particular SMB traffic
incurred by explorer.exe. It's a Shell issue.
1.2
Is the target a DFS path or not?
Yes, go to 1.2.1
No, go to 1.2.2
1.2.1
Is the client downloading/uploading against the nearest file server?
Yes, go to 1.2.1.1
No, go to 1.2.1.2
1.2.1.1
Try to download/upload against that file server using the Non-DFS share path. Still slow?
Yes, go to 1.2.1.1.1
No, go to 1.2.1.1.2
1.2.1.1.1
Not a DFS issue. Capture Network Monitor trace from both sides to identify the pattern of the slowness.
1.2.1.1.2
This is unlikely to occur because the conclusion is contradictory to itself. Start from the beginning to double
check.
1.2.1.2
Same situation as 1.1.1.2. Use dfsutil.exe to clear local domain and referral cache. Then visit the DFS path again
and capture Network Monitor trace from the client to study why the client goes to a wrong file server or DFS root server.
1.2.2
Same as 1.2.1.1.1. It's not a DFS issue. Capture Network Monitor trace from both sides to identify the pattern of
the slowness.
1.3
Follow 1.1 and then 1.2.
