Sg200 cannot join to catalyst 2495

I have 3 existing switches, two for Catalyst 2495, and one for SG200-26,
Now I add new one for SG200-26, then connect to Catalyst 2495 any port, or connect to SG200-26 any port, fail, 2495 switch will stop the port, even SG200 connect port light up, but the network is stop, cannot ping each other!
I have tried reset the new SG200-26 to DHCP or manually set IP address with the same subnet. not working, I have update all firmware.
My network no vlan setup, simple one.
I don't why my existing SG200-26 connect to 2950 is working, why add new one is not working?
I have configured 2950 with switch port, and sg200 also set as trunk port/ auto neg. when connect them. no luck!
Any idea?

So you are connecting a 2950 to a SG200?
What config is on the port on the 2950?

Cannot join time capsule airport network from iPad 2 or iPhone 4

I have recently setup a new time capsule airport base station network with my new iMac (27-inch, late 2012) running OSX 10.8.2. Wi-Fe network works fine for internet access and printing from the iMac but I cannot join the wi-fi network from our iPad 2 or iphones. The network is seen in the wi-fi setup when wi-fi is turned on with the ipad and phone but does not establish a connection. An IP address and subnet mask show under the DHCP settings but the connection is not established. (Continuous revolving wheel).
Any help would be appreciated.

The airport utility in Mountain Lion is a toyland version.. see bottom of post for installing v5.6 which improves the ability to actually make the TC do what you want.
For whatever reason the iphone/ipad seem sensitive to wireless channels.. which Apple auto rotate.. I think it is bluetooth connection stuff.
Anyhow jump in and set the following.
Wireless should have strictly SMB names.. short no spaces, pure alphanumeric.
Use WPA2 Personal security.
Lock the wireless channel for 2.4ghz.. try in the following order.. 11, 6, 1 (those are the only non-overlapping channels) you can try in turn for which is best but if 11 works well stick to it.. Outside USA you can also use 13.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

My iPhone 4S has stopped receiving iMessages, cannot send/load any pictures over whatsapp, cannot join the wifi in my house anymore. What has happened to my iPhone i haven't made any changes?

My iPhone 4S has stopped receiving/sending iMessages, cannot send/load any pictures over whatsapp and cannot join the wifi in my house anymore.
Essentially all the things I use my phone for have now stopped working. I constantly have 3G connected (even though i dont want to use it, i want to connect to the wifi in my house) but still when I try to download/ send a picture over whatsapp it comes up with an error message saying the server is unverified, or something equally ridiculous.
I deleted the app so i could reinstall it (as if that would help), but the app store is started saying "unable to connect", despite 3G, so that bright idea died out pretty sharpish.
Whenever i try to turn on iMessage, it asks for my Apple ID password, which I know I've typed in correctly because I reset the **** thing about 4 times due to it apparently being "incorrect". Even so, it repeatedly asks for the password over and over as soon as I've entered it, saying it was "unable to connect" before a final "incorrect password" message pops up just to add an extra smack of annoyance.
I haven't changed a single setting on my iPhone whatsoever. It just suddenly started spiralling into what is now £28/month-worth of pure frustration.
I don't even have any music or photos on it as I had to free up 3.5GB of space on the **** thing to allow it to update, naively thinking that would solve the problem, but alas it did not.
I have seen a few questions posted like this one, usually just one of the problems I have, but I seem to have rounded up the whole bunch (lucky me). None of the previously posted questions have received any replies.
Can some please help me! Honestly, if i see another "unable to..." or "unverified source" pop up again I'll probably smash the thing against the side of my house.
Cheers.

On your iPad, go to [Settings > General > Reset > Reset Network Settings] Once that is done, re-connect your iPad to your wifi network.

My iPhone 4s cannot join a public unsecured network but my iPad and macbook can. I have reset the network settings twice. Both times it worked, but only for a few minutes. What can I do?

My iphone 4s cannot join a public unsecured network, but my ipad and macbook can with no problems. I have reset the network settings on the iphone twice. Both times that fixed the problem but only for a few minutes, then I get the "cannot join network" message again. Please help! What can I do?

Anyone have any ideas or information to help with this? Any help and consideration is MUCH appreciated.

New 2012 R2 domain - xp clients cannot join or print

I just migrated a 2003 domain to 2012 R2.   Things were working ok & then XP clients became AD stupid.
Steps I took:
Added a VM 2012 R2 DC to the domain. Server had DNS installed. Ran dcdiag & bpa and resolved any issues.
About a week later I moved all roles over to the VM DC.
Tore down one of the NT2003 DCs (not VM) and rebuit it as a 2012 R2 DC w/DNS. Ran dcdiag & bpa and resolved any issues. Had problems with DNS scavenging removing some static records. readded records & made sure the "Delete
record when it becomes stale" was unchecked on all static records (all fwd & rev zones).
Moved all roles from the VM DC to the hardware DC.
After a week I tore down the 2nd (& last) nt2003 DC (not VM) and rebuilt it as a 2012 R2 DC w/DNS. Ran dcdiag/bpa and fixed any issues. Also ran it on the other DCs.
Removed the VM 2012 R2 DC from the domain (demote, remove features, remove from domain, power off, delete VM).
Everything seems to be working fine. dcdiags look clean, event logs seem good.
Bump forest/domain to 2012 R2 native.
Then, a few days later, it goes bad. I (after hours) install all accumulated updates on both DCs. Reboot both.
Next AM a user calls. Her thin client cannot connect to the terminal services server. DNS has deleted its dns record, even though the delete when stale was unchecked. :| So I readd the static record and turn off scavenging.
Problem solved.
Next call s from a XP user (we have XP, Win 7, and thin clients). She cannot print. Printers show "cannot connect". Try various things to no avail. Check Win 7 boxes and they're working fine & printers are connected.
Note that the XP & Win7 boxes all pull their DHCP address from the same dhcp server/scope.
Review error logs and run dcdiag. There are several somewhat esoteric errors. After several hours or tail chasing I decide to take a more scorched earth tack. I demote the 2nd DC and remove AD & DNS from it. After demotion and role
removal I check AD and it still shows the DC. I remove the now just a server from the domain. Clean up DNS & AD removing all traces. This takes a while as I have to run variuos scripts (tahnk you google) to ensure AD is clean.
Run dcdiag and resolve issues. Even a detailed dcdiag comes out clean. Replication tests show the old server is now forgotten.
Check XP boxes and they still show printers as "cannot connect".
Remove a XP PC from the domain. Try to rejoin and I get a error. Rename it and still get the error. I can ping, nslookup, etc and they return the correct IP.
I've tried the simple change the join a domain in system properties. That gives a somewht non descript error. The network identification wizard seemed to find the domain but didn't work. As it was trying to find the PC in AD, I went ahead
and added it via AD users& Computer console. Run the wizard and it tells me it found the record in AD. It then says "a domain controller for the domain [ourdomain] could not be contacted." !? Yet the prior screen it told
me it had found the record for the PC on the DC.
nslookup for ourdomain.local as well as dcname.ourdomain.local resolve correctly. Tried chenging the PC to static - no change. Rename the old win 2012 R2 dc (now just a server outside the domain), reboot, and the try to rejoin the domain.
Works flawlessly.
BTW - We're running tcpip w/o netbios over tcpip.
So basically my XP boxes cannot use AD printers and cannot join the domain. IDK if they're picking up gp updates (I'll check in the AM), but I suspect they're not.
Short of buying a truckload of Win 7 licenses and reloading OSs, what can I do to fix this?
Details on the XP box error (fyi - I did a record to record comparison to a Win 2008 domain's SRV records and they look identical (except, fo course, the domain& server names)) :
The domain name [ourdomain] might be a NetBIOS domain name. If this is the case, verify that the domain name is properly registered with WINS.
If you are certain that the name is not a NetBIOS domain name, then the following information can help you troubleshoot your DNS configuration.
The following error occurred when DNS was queried for the service location (SRV) resource record used to locate a domain controller for domain [ourdomain]:
The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)
The query was for the SRV record for _ldap._tcp.dc._msdcs.[ourdomain]
Common causes of this error include the following:
- The DNS SRV record is not registered in DNS.
- One or more of the following zones do not include delegation to its child zone:
[ourdomain]

ORA-02047: cannot join the distributed transaction in progress

Hi All,
My requirement is to do COMMIT Transactions in BULK like 100 rows. I am doing update in Oracle and SQL Server both. Following statement update the SQL Server side:
v_sqlstr :=
'update JDETAIL set interfacedate = getdate() where company ='
|| v_company
|| ' and Recordnumber= '
|| TO_NUMBER (v_recordNumber)
|| ' COMMIT TRANSACTION';
num_rows :=
DBMS_HS_PASSTHROUGH.execute_immediate@ex_test (v_sqlstr);
After this I am calling Oracle Update Procedure . In Oracle UPDATE Procedure when I write AUTONOMOUS TRANSACTIONS AND Commit then it works fine BUT when I don't COMMIT which I don't want because I want to COMMIT in BATCHES then following error is thrown
ORA-02047: cannot join the distributed transaction in progress
Thanks

you can't put the commit transaction into a pasthrough statement.
Oracle Gateway starts the transaction, so you need to write the code in a way that allows the gateway to perform the commit. When doing a commit in a passhrough statement the gateway has no control over the committed data. Thus you get the error unless you start an autonomous transaction.
Why do you need to call the update in a pasthrough statement? Why not in a PL/SQl code block with a counter that commits after 100 rows?

MacBook Pro sees wireless networks but cannot join any. Connection timeout error

I have a MacBook Pro here that sees all wireless networks but cannot join any. It gives a connection timeout error with every one.
Internet access via ethernet cable works just fine.

It's not uncommon for you to "see" a great many networks, dozens even, yet you not be able to connect to any of them even if they are "open" (no lock icon). There may be a number of reasons for that, such as they're too weak for a reliable connection, or the router may limit connections to only specified devices.
There is only one way to achieve a reliable network connection, and that's for you to connect to your own wireless router. Even that doesn't work if its signal is too weak or if there are many competing wireless networks in your area.
If it's your own AirPort Base Station you're trying to use but can't, the latter could be the reason. The only way to mitigate the effects of wireless interference is to use 802.11n and 5 GHz whenever practicable. Even today you may only find one or two 5 GHz networks being used in an otherwise "crowded" area.

Cannot join network after ios update

After ios update i cannot join on my ipad network

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Cannot join tables used in the workbook. Join "" not found in the EUL. Atte

Trying to migrate workbooks from one instance to other using discoverer 10.1.2.48.18 i am getting the following error
Unable to open the worksheet requested.
- OracleBI Discoverer was unable to find the worksheet that was requested.
- BIB-10310 An unknown exception occurred.
- Cannot join tables used in the workbook. Join "" not found in the EUL. Attempt to open workbook failed.
but its fine one instance , and in prod i am getting above weird error.
does anybody know how to rectify this.

Note:267476.1 - for those who can't get into metalink but still need to know the answer
Subject: Discoverer Workbook Fails With 'Cannot join tables.Item dependency "" not found in EUL' After EUL Migration, Importing Or Cloning
Doc ID: Note:267476.1 Type: PROBLEM
Last Revision Date: 28-APR-2005 Status: PUBLISHED
The information in this document applies to:
Oracle Discoverer - Version: 4.1 to 10.1
This problem can occur on any platform.
Symptoms
Opening a workbook migrated from one instance to another results in the following errors:
* Unable to load EUL item ...
* Cannot join tables. Item dependency "" not found in EUL.
* Illegal operation... DIS4USR OR DIS5USR caused an invalid page fault in module....
If using the workbook dump utility, you may notice:
* Found in EUL by id *** Name has changed to .. where the new name is really the wrong column
It seems that items are matched by internal item identifiers (IDs) and not by developer keys and names.
Changes
Migrating from one environment to another. For example, you may have performed a database export / import of the EUL schema from DEV to TEST
Cause
The timestamp is the same for both EULs, what can be confirmed by the following SQL statement:
* Discoverer 4:
SQL> select ver_eul_timestamp from eul4_versions;
* Discoverer 9.0.2 , 9.0.4, 10.1 the script is:
SQL> select ver_eul_timestamp from eul5_versions;
If the result of the sql output is the same in both EULs, it means that timestamp of both EULs are the same. Discoverer assumes that the EUL are exactly the same (e.g. this can happedn when one of them is created with export/import of the other EUL schema using database export/import utilities) and this is the reason it tries to match items by identifiers and not by developer keys or names.
Solution
Change the column ver_eul_timestamp in the eul4_versions (4.1) or eul5_versions(9.0.2 - 10.1)tables to be something different in the destination EUL. The format of this column is like year:month:day:seconds:milliseconds
Example:
* Discoverer 4.1:
sql> update EUL4_VERSIONS set VER_EUL_TIMESTAMP =TO_CHAR(SYSDATE, 'YYYYMMDDHH24MISS');
sql> commit;
* Discoverer 9.0.2:
SQL> update EUL5_VERSIONS set VER_EUL_TIMESTAMP = TO_CHAR(SYSDATE, 'YYYYMMDDHH24MISS');
sql> commit;
* Discoverer 9.0.4 -10.1:
Run the script: EUL5_id.sql as the eulowner ID
o For 9.0.4 -- This is found on a PC with the Discoverer Administrator installed in drive:\Oracle Home\discoverer\sql
o For 10.1.0 -- This is found on a PC with the Discoverer Administrator installed in drive:\Oracle Home\discoverer\util

Cannot join tables .item dependency not found in EUL

cannot join tables.item dependency "a04 currency->b27 exchange rate 1" not found in EUL
I am not able to open a workbook in discoverer in user edition.
It seems I unwittingly deleted a join in the end user layer. I have tried to redo the join but I have not been able to replicate the join required. Is there any way I can work around this join without having to scrap my workbook? Rebuilding the workbook took a long time.
Any suggestions would dig me out of a deep hole

Hey,
I got this Error after our environment was cloned from APPS Production (PRD) instance to Development (DEV). I saved my workbooks that were 'under construction' as *.DIS files as local copies to the network.
After the clone was finished I imported the latest Business Areas back onto DEV, but there was no way I could open my saved local workbooks due to the error "cannot join tables .item dependency not found in EUL".
After some hours of rage, by accident we found out that one of our Functional Consultants was able to open these workbooks! It turned out that when I logged on to APPS under the user_name (from FND_USER) of this person I could indeed open the workbooks and save them to the database after which I could open them again with my own user.
So -in this case- I solved the problem by using a different user to open the workbooks. But who knows next time...
Good luck, you'll need it.

Did the iPod connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Try changing the security on the router. Starts with no security as a test.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

TS3304 cannot join networks on wi-fi on ipad or iphone

All of a sudden in the last week I cannot join the wireless network for either IPAD1, IPAD2 or Iphone. Does this have something to do with the updated software (5.1.1) on these devices or my Comcast router? We've called Comcast and Apple and resetting the wireless nework on the devices does not seem to help. Please advise.

Longshot, but try changing your brightness setting & then try connecting.
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
