TT0846: Data store connection invalid or not current

In one of our environments we started getting TT0846 error randomly.
Everytime we get this error we have to restart our application to reconnect to datasore.
When we checked the error logs, we found the following:

What I could gather from this is that Replication agent tried to change permissions of transaction logs and was unable to and the datastore was marked invalid and disconnected.
But I have not been able to find a reason for this error occurring, the environment has not been touched, there have been changes made to database objects but can they lead to this error.
If not, what is causing the error and how can we resolve it.
Thanks, your help is much appreciated.

You have a permission problem. For some reason your logfiles have the owner/group 'timesten:timesten' but based on the information from ttVersion and from the permissions on the checkpoint file they should be 'timesten:db'a. Also, the permissions shoiuld be rw-rw---- but they are set to rw-------. There could be several reasons for this, the most likely are:
1. Incorrect permissions set on the directory that holds the transaction log files.
2. TimesTen daemon processes running with incorrect userid/group.
3. Instance administrator user (timesten) no longer has group membership of the protection group (dba).
For (1), this would be 'user error'. For (2) and (3), this could only happen if permissions on TimesTen install files have been manually changed (something that should not be done without a very clear understanding of how the permissiosn need to be set) or the uid/gid for the instance administrator user has been changed at the O/S level after installing TimesTen or the 'timesten' user has been removed from the 'dba' group.
I would suggest that you check all these and see what may have been done at the O/S level.

The error message suggests that the system is running out of semaphores although plenty seem to be configured:
kernel.sem = 400 32000 512 5029
Could it be that there are other programs on this machine as this user using semaphores?
Have you made changes to the kernel parameters and haven't made them permanent with
# /sbin/sysctl -p
or a re-boot?
If you've done a # /sbin/sysctl -p have you recycled the TT daemon
$ ttDaemonAdmin -restart
So TT takes up the new settings?

HT1688 when you double tap the home button to go back to your other apps are those apps always running and using cellular data even if I am not currently using them? I thought it froze them and didn't use data other that a select few apps like Facebook,

when you double tap the home button to go back to your other apps are those apps always running and using cellular data even if I am not currently using them? I thought it froze them and didn't use data other that a select few apps like Facebook, email, etc. Also I always select no when I download an app and it wants me to have those push notifications. Because that would mean that I would have to delete my apps after everytime I just them from that bar and that would be very annoying and just stupid. Or maybe apps do use data and it's just a big scheme to make everyone go over on their data plans.

This should help: http://speirs.org/blog/2012/1/2/misconceptions-about-ios-multitasking.html.

AM 7.1 legacy, data store connection.

Hi!
I've installed Access Manager 7.1 in legacy mode, and I access it via the java api, using the full SDK.
If I want to assign a user to a group, and the user and the group are assigned to different realms, I get the following error:
Message:Unable to get attributes from data store.
at com.sun.identity.idm.IdUtils.convertAMException(IdUtils.java:661)
at com.iplanet.am.sdk.AMSDKRepo.getDN(AMSDKRepo.java:1865)

at com.sun.identity.idm.server.IdServicesImpl.modifyMemberShip(IdServicesImpl.java:1117)
at com.sun.identity.idm.AMIdentity.addMember(AMIdentity.java:968)
If the user and the group are in the same realm, there is no problem.
The same problem occurs if I want to assign a user to a role, witch has different realm.
Could you please provide me some hints on what may I do wrong?

I'm still cannot pass through this problem.
Please, give me some hint.

I cannot get my IPad air to connect to wireless in home. Two other iPad 2's connect as well as laptops. I have already exchanged one iPad air and none want to connect. Husband has taken iPad air to the apple store, connects here but not here. Who can help

Can someone please help??? I received am IPad air in November for my birthday and have not been able to use yet, I could not get it to connect so I returned it for another iPad air. And cannot get it to connect to wireless either. I have three other iPad 2's and laptops in home and everything connects with no problem. What is the deal with these iPad airs? My husband took the iPad to Apple store, it works there but didn't change anything so it won't work at home. Do I need to step down to old IPad since that's all that will connect in home. This is crazy,!!! How can I get my IPad air working in my home.???

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 droping 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

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 attach data store shared-memory segment using JDBC (TT0837)

I'm currently evaluating TimesTen during which I've encountered some problems.
All of the sudden my small Java app fails to connect to the TT data source.
Though I can still connect to the data source using ttisql.
Everything worked without problems until I started poking around in the ODBC administrator (Windows 2K).
I wanted to increase permanent data size so I changed some of the parameters.
After that my Java app fails to connect with the following message:
DriverManager.getConnection("jdbc:timesten:direct:dsn=rundata_tt60;OverWrite=0;threadsafe=1;durablecommits=0")
trying driver[className=com.timesten.jdbc.TimesTenDriver,com.timesten.jdbc.TimesTenDriver@addbf1]
SQLException: SQLState(08001) vendor code(837)
java.sql.SQLException: [TimesTen][TimesTen 6.0.4 ODBC Driver][TimesTen]TT0837: Cannot attach data store shared-memory segment, error 8 -- file "db.c", lineno 8846, procedure "sbDbConnect()"
The TT manual hasn't really provided any good explanation what the error code means.
Obviusly I'v already tried restoring the original ODBC parameters without any luck.
Ideas..anyone?

Peter,
Not sure if you have resolved this issue or not. In any case, here are some information to look into.
- On Windows 32-bit, the allocation of shared data segment doesn't work the same way like on Unix and Linux. As a result, the maximum TimesTen database size one can allocate is much smaller on the Windows platform than on other platforms.
- Windows error 8 means ERROR_NOT_ENOUGH_MEMORY: not enough storage is available to process this command.
- TimesTen TT0837 says the system was unable to attach a shared memory segment during a data store creation or data store connection operation.
- What was the largest successful perm-size and temp-size you used when allocating the TimesTen database?
* One explanation for why you were able to connect using ttIsql is that it doesn't use much of the DLLs, whereas your Java application typically has a lot more DLLs.
* As a troubleshooting step, you can try reduce your Temp-size to a very small size and just see if you can connect to the data store. Eventually, you may need to reduce your perm-size to get Windows to fit the shared data segment in the process space.
By the way the TimesTen documentation has been modified to document this error as follows:
Unable to attach to a shared memory segment during a data store creation or data store connection operation.
You will receive this error if a process cannot attach to the shared memory segment for the data store.
On UNIX or Linux systems, the shmat call can fail due to one of:
- The application does not have access to the shared memory segment. In this case the system error code is EACCESS.
- The system cannot allocate memory to keep track of the allocation, or there is not enough data space to fit the segment. In this case the system error code is ENOMEM.
- The attach exceeds the system limit on the number of shared memory segments for the process. In this case the system error code is EMFILE.
It is possible that some UNIX or Linux systems will have additional possible causes for the error. The shmat man page lists the possibilities.
On Windows systems, the error could occur because of one of these reasons:
- Access denied
- The system has no handles available.
- The segment cannot be fit into the data section
Hope this helps.

How create data store with PermSize 512MB on WIN32?

Hi!
How create data store with PermSize > 512MB on WIN32? If I set PermSize > 512MB on WIN32, then data store becomes invalid.

Thanks for the details. As I mentioned, due to issues with the way Windows manages memory and address space it is generally not possible to create a datastore larger than around 700 Mb on WIN32. Sometimes you may be lucky and get close to 1 GB but usually not. The issue is as follows; on Windows, a TimesTen datastore is a shared mapping created from memory backed by the paging file. This shared mapping must be mapped into the process address space as a contiguous range of addresses. So, if you have a 1 GB datastore then your process needs to have a contiguous 1 GB range of addresses free in order to be able to connect to (map) the datastore. Unfortunately the default behaviour of Windows is to map DLLs into a process address space all over the place and any process that uses any significant number of DLLs is very unlikely to have a contiguous free address range larger than 500-700 Mb.
This problem does not exist with other O/S such as Unix or Linux nor does it exist with 64-bit Windows. So, if you need to use a cache or datastore larger than around 700 Mb you need to use either 64-it Windows or another O/S. Note that even on 32-bit Linux/Unix TimesTen datastores are limited to a maximum size of 2 GB. If you need more than 2 GB you need to use a 64-bit O/S.

Unity Data Store for unity 8

Guys,
Im installing unity 8.0.3 , but unfortunately stuck at " cisco data store" .When i searched google itsays to install "sql server 2005 sp3" or"sql server express 2005 sp3". I installed express , but unity assistant still shows the result as "failed".
Any help from u guys will be appreciatable.

You should take a look at the "Read Me" file as it states that the Unity Data Store DVD for Unity 8 is NOT available for download. Refer to the following:
Do Not Use the Cisco Unity Data Store 2000 Disc from Cisco Unity 7.x and Earlier to Upgrade to Cisco Unity 8.0
If you are upgrading to Cisco Unity 8.0 and reinstalling software on the Cisco Unity server (for example, because you are replacing the server or upgrading to Windows Server 2003), you must use the Data Store 2000 disc that ships with Cisco Unity 8.0. The Data Store 2000 disc that shipped with earlier versions of Cisco Unity has a different directory structure, and the Cisco Unity System Setup Assistant, which guides you through installing and configuring Cisco Unity 8.0, will not recognize the Data Store 2000 disc that shipped with Cisco Unity 7.x and earlier. (If you paid for an upgrade to SQL Server 2005, we will ship you a Data Store 2005 disc with the rest of your Cisco Unity software.)
The Cisco Unity 8.0 version of the Data Store 2000 disc is not available for download on Cisco.com. To perform an upgrade that requires reinstalling software on the Cisco Unity server, you must either wait for the Cisco Unity 8.0 installation discs to arrive or manually install SQL Server 2000 or MSDE 2000. Manually installing the application is not documented and, therefore, not supported.
There's your answer. You need to order the upgrade kit from Cisco in order to get the proper DVD.

Data Server Connection Problem in MII 12.1 Version.

Hello Experts,
I am using two instances of MII 12.1.8 Build (20), at which am recently facing problems in the Data Server Connections.
Am not able to connect to the Data Servers using connectors [IDBC, Virtual IDBC].
When I checked the status of the servers, it is showing the status as running but there is no available connections.
When trying to create the query templates I dont get the available tables list populated too.
The driver details for jdbc used are the default ones,
For IDBC,
JDBC Driver : com.inet.tds.TdsDriver
ServerURL : jdbc:inetdae:<ip_addr>:1433?database=<db_name>&sql7=true
For virtual IDBC,
ServerPackage: com.sap.xmii.Illuminator.connectors.Proxy
The error that we got in the LogViewer.
Log Record Details

Actually the connections were working fine, in both the MII instances am working on (of the same build).
Now they both have gone down, all of a sudden
Please suggest the checks and corrections, I should do to overcome this hurdle.
Thanks for any help in Advance.

Automatic pc Data Store with Time capsule possible?

I warnt to Bus a Time capsule and want in Addition To my Mac Data Storage automatically Safe the Data from a PCS. Is this possible? How?

Sorry but your question is a little hard to follow.. do you want to backup a PC..
The TC is not now or ever a data store.. you should not use a TC as a file server without serious consideration to the total lack of backups. TC cannot back itself up.. nor can any software you have backup network drives unless you purchase one.
A backup software can certainly backup a PC to the TC.
You need to buy it though.
Genie Time Line Pro is often recommended.

Disable Data Port Connections

I have a WRT54G2 setup in the company. I want the unit to be used for wireless access only. I would like to disable the data port connections that are not being used.
Has anyone done this before or know of how to do so?

I thought of causing damage to those ports too. Maybe lLightly crazy glue in a few male RJ45's is another thought I had.
Thanks again GV!

Not currently available in the U.S. Store - only on Wi-fi connection?

Hi All,
I have an issue with access to iTunes and App Store when connected via wi-fi.
The error that says "The item you have requested is not currently available in the U.S. Store".
The strange thing is that if I switch off wi-fi and connect via 3G it works without any problems?
Any one got any solutions for this?

Use the proper store for your country.

Hi Ian,
Can you please answer the following / provide the following information:
1. What are your kernel parameters relating to semaphores set to? Is anything else on the mahcine using significant numbers of semaphores?
2. Please provide the output of the following shell commands:
ls -ld /u01
ls -ld /u01/ttdata
ls -ld /u01/ttdata/datastores
ls -ld /u01/ttdata/logs
3. Please provide an excerpt of the detailed message log (ttmesg.log) between around 16:38 and 16:40 (i.e. from a little while before the problem until after the problem).
Thanks,
Chris

On i-pad, when try to enable itunes match, it says, "you are not currently subscribed to iTunes Match. Use iTunes on your computer to subscribe." I am subscribed though! Then it says no my request and item not available in the U.S. store. WWJD?

On i-pad, when I try to enable itunes match, it says, "you are not currently subscribed to iTunes Match. Use iTunes on your computer to subscribe." I am subscribed though! Then it says no to my request and, "item not available in the U.S. store." My Mac will not use update iTunes to any later version than the one I have because my os is also out of date, but when I try to update that i cant, so what do I have to do? Please don't tell me I have to buy a new Mac to be up to date.

On the iOS device you must be logged into the store with the exact same Apple ID you used to originally purchase the service. Go to Setting > iTunes & App Stores and if necessary sign out/in and then enable iTM.
