Cache server metrics-Current Open connections
hello all,
I have a query regarding the dashboard cache server metrics in CMC.
When I run the dashboards, data is getting cached in the cache memory, but dashboards are using that cached data only when the "Current Open connections" in the "Dashboard cache server metric" is non-zero.
i.e., example when I run the dashboards for the first time, "Current Open connections" under Cache server metrics is 10. When I run the dashboards immediately with in 20 minutes, results would come very fast. But after 20 minutes , the "Current Open connections" are becoming 0(connections seems to be expiring) and after I run the dashboards, they are performing slowly though the data is present in the cache memory.
I have tried changing the "Idle Connection timeout" to 240 minutes from the existing 60 minutes, still "Current Open connections" under Cache server metrics is becoming 0 after 20 minutes.
Kindly help me as this is affecting the dashboards performance.
Thank you.
Hello,
Appreciate any help on this. Attached is the screenshot of what I was referring to. "Currently Open Connections" becoming 0 in 20 minutes(even after the idle time connection timeout is increased to 240 minutes) , while the number of open connections shows the number.

Metrics " Current Open Cursors Count "
Hi,
I get an Alert message Metrics " Current Open Cursors Count is at 1201 '" on 10g database version 10.2.0.1.0 . Can anyone help me to solve this.
Thanks
SreeSree,
The Metric corresponds to the number of records in V$OPEN_CURSOR internal view.
The number of open cursors is a function of the number of concurrent users and the application code ,so 1201 may not necessaryly indicate a problem – it could be that you system is genuinely very busy.
You should start worrying if the number of open cursors consistently grows over time (while the workload is steady). In this case you may have a “cursor leak” – a piece of code that opens a cursor, but does not close it.
You can check that with
select substr(sql_text,1,30) , count(*) cnt
from v$open_cursor
group by substr(sql_text,1,30)
order by 2 desc
If the current open cursor are getting close to the max allowed(OPEN_CURSOR parameter), you may reset them using share pool flush (note that the shared pool flush may have some small performance impact on the system).
Hope that helps, -
"Current Open Cursors Count" Warning
I am getting this warning lately in my Grid Control repository database
Metrics "Current Open Cursors Count" is at 1563
Open cursors value fluctuates between 1400 and 2300.
Is my open cursor threshold set too low (warning: default 1200, critical: not defined) and this is normal Grid Control behavior or I have some kind of problem here?
Oracle 10g Grid Control (10.2.0.5)
Linux x86Actually, it is just a message telling you that the Open Cursor Count has exceeded the threshold limit. If the number of open cursors continues to increase over time (from day to day, and constantly gets larger and larger, never gets smaller) then it may indicate a problem.
I would suggest that you set the threshold to at least 2300, then wait and see if the alert shows up again. If it does then further analysis may be required to determine the root cause.
I hope this helps!

TCP Open Connection and Error Code 1
So, I have a client that is supposed to continuously try to connect to a server using TCP Open Connection.vi. When the connection is established, the loop is supposed to exit.
psuedocode for the loop I have is as follows (similar code, LV 7.1, exhibiting the same problem is attached)
while (error)
attempt to open connection
Pretty simple, right?
I've had no issues with servers written in LabVIEW, but when attempting to integrate with a server that was written in C, it appeared that the client created multiple connections. I have been able to reproduce this problem by writing a server with Java. The C server was on a remote machine, the Java server on a local. Both see different numbers of additional connections (3 for C, 2 for Java).
Looking at the error codes, I am getting a bunch of code 56 (timeout, expected) and the ocassional code 1 (unexpected). I have noticed that whenever I have this multiple connection problem, I show an error code 1 right before the valid connection attempt and loop exit. Is there someway that a connection is being established (or partially established), but labVIEW is still returning an error? Is there a better way to verify that a TCP connection was actually successful?
Here is example output from the attached code, it shows the error codes generated

Sample Client.vi 21 KBHello,
I’m a little curious why you are setting up your client like
this. If it is your objective to just
have the client wait until a connection is made, why not just have the TCP
connect VI have timeout value of ‘-1’ meaning “do not timeout”. This will allow the built-in TCP event
structure to listen for connections and ‘wake up’ your program when a
connection is established. I say this,
because the error messages seem to be dependant on the timeout values. For example, wire in 1ms to the timeout and
see how the messages differ in timeouts as opposed to wiring in “2000” for the
timeout value. This is because the
Connect VI attempts a connection and waits only the specified timeout before
abandoning that attempt and continuing with another attempt. I’m betting in your case connecting to the
server takes longer than your timeout value, so the connection is initiated by
your LV client, the handshaking takes place, your server indicates that a
connection is being made, and sometime during this process your timeout expires
and LV tries the process again thus you see the multiple connections. Go ahead and try this as an experiment – take
your VI, and instead of using ‘localhost’ use the IP address of your favorite
website and change the remote port to port 80.
Change the timeout to -1 and wait for the connection, then change the timeout
to 1 and see all the timeout errors given.
Hopefully this answers your question, please let me know if
you have any additional questions or if this is inaccurate/unclear.

Why "slow server alert" when NO running requests and NO open connections??
The snapshot below says it all. Why on earth would my dev machine with no running requests, and no open database connections, kick off a slow server alert?
I will tell you that at the exact same time this snapshot was generated, my other two servers WERE hung and were reporting "Unresponsive alerts", and they connect to the same databases. I am chasing down a chronic communication failure between our database and web servers where everything with a databae connection gets locked/hung at the same time every night, 7 days a week. The hang lasts anywhere from a few mins to 40+ mins.
Is this why my dev server would report slow? And if so, is it the skimmers or what that's causing a slow server alert?? Would it only report "Unresponsive" if there were actual page requests hanging, vs. a "Slow Server Alert"?
This is CF10 (update 12) 64-bit on Windows 2008 R2, IIS 7, connecting to separate Oracle 11g server.
Thanks for any insights.

at java.lanI'm pretty sure the problem here is somehow related to my other post, but for shites and grins I would still like to know how I can receive a Slow Server alert when no actual page requests are running and it says there are 0 open connections to any of the datasources.
-
Hi, since this morning i receive this message on my Mac Air (10.8.5) when i open iCal (which is synced through iCloud): "The server responded with an error. The server is currently unreachable or the connection was blocked". You know what it can be?
Thanks for your help!Are you behind a firewall at work or elsewhere? Does you calendar sync with some other system like google (could be the google server is not responding)? All we know from the message is that your mac cannot reach the server. Maybe try later. Are you using wifi or have an ethernet connection to the router?
-
Could not open connection to the SERVER
Below is the error message that i have encountered.
I am using Java version 7.
Also tried installing the previous versions as well.
But when i check the connection using the ODBS data source administrator i was able to connect the server.

Failed to open connection error message on Crystal Server
I have recently upgraded my desktop to Windows 7. Crystal Reports XI Developer works fine on this new system as it did on my earlier Vista system. I can create and run reports with no problems on each of these system using Developer.
The problem I am experiencing is this: when I publish, using the Publishing Wizard, a report on my Crystal Server using my Windows 7 system, the report does not work. Instead, the error message: 'Failed to open connection' appears from Crystal Report Viewer.
If I open the same report using my Developer license on my old Vista machine and then re-save it, I can publish it to my CR Server and it runs successfully.
ODBC is used on all systems and all appear to be 32 bit versions, albeit different version numbers.
This problem can be repeated with any of the many reports currently in use.HI Don,
Let's see if I understand what you're saying:
When a report is created on a legacy desktop in CR Developer, the ODBC connection on that computer works with direct access to the SQL Server 2008 on my Windows Server 2003 R2 system. I can then also publish these using the Publishing Wizard to the CRS these same reports and they run successfully; no connection issues, works great.
However, when a report is created on my 64 bit Windows 7 desktop in CR Developer, the ODBC connection on that computer also works well with direct access to the SQL Server 2008 on my Windows Server 2003 R2 system. BUT, when I then publish these using the Publishing Wizard to the CRS these same reports do NOT successfully connect to the database and that is when I get the Crystal Viewer message about the connection failed.
So, I would assume then that Crystal Server on my Windows Server 2003 system is similar enough to older MDAC criteria on legacy systems but different enough my Win7 desktop to introduce the problem even though Developer on that same Win7 system works fine directly against the SQL DB.
If this is all correct, then I either need a legacy MDAC to work on my Win7 system, or an updated MDAC\WDAC for Crystal Server to use.
By the way, I'm using ODBC and here are some details from the Component Checker:
Server:
MDAC 2.8 SP2 on Windows Server 2003 SP2
Desktops:
MDAC 2.8 SP1 on Windows XP SP3 - on an XP machine that works fine
UNKNOWN on Vista (but it works fine with CRS)
UNKNOWN on Windows 7 - (doesn't work with CRS - must be a different UNKNOWN than on Vista)
Thanks for your assistance as this is rather important -
Bob. -
Since upgrading to Yosemite on my iMac I am frequently getting "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again". This is with both a WiFi and Ethernet connection. The server is working fine from other devices using WiFi onto it such as iPhones, iPads, MacBook (which is also on Yosemite) so don't believe its an issue with the server.
I am also noticing page load very slowly when this problem is not occurring.Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2. -
hi, i am trying to open and view a report that comes from another server with different odbc connection
i created a crystal report for a mysql database on my machine and everything works great
but we have other reports that come from other machines with different odbc connection
and this its not working when opens the report asks for credentials
and i cannot use the remote ip for these reports that come from other machine
question
if i cannot connect to remote ip to open the report
for each report i have to create a database the report database on my machine and then open the report ?
or there is some other way to open the report ?
i am using visual studio 2013 and mysql and
<add key="MYSQLODBCDRIVER" value="{MySQL ODBC 5.3 UNICODE Driver}"/>
thanksshort
i have a report that it was created on another server with a specific dsn
now i am trying to open the report on my machine
the database from the other server does not exist on my machine
the server machine where the report was created the ip its not accessible
question ?
can i open the report on my machine or its impossible ?
thanks -
I have recently switched from MobileMe to iCloud and I now getting an error message in iCal :
"The server is currently unable to handle the connection due to a temporary overloading or maintenance of the server. If this continues you should contact the server administrator.
You may try to connect to the server again or take the account offline."
Since I am working from home and I am not on a server other than iCloud I don't understand why I am getting this message. (for 3 days). How do I fix it?TomCT60,
Is your MacBook using Mac OS X 10.6.8 as indicated in your post? If so you will not be able to fully integrate with iCloud.
iCloud and Snow Leopard, by Roger Wilmut describes what iCloud options are available for Snow Leopard.

Server Admin refuses to connect to server when run locally or remotely. Upon investigating, servermgrd seems to run but when I run network utilities and port scan the server, neither port 311 or 687 are open. All other services appear to be running fine. No firewall is running. Server Monitor also has the same problems but WorkGroup Manager seems to work fine.
About 3 weeks ago, I had the problem and after trying many things, I did a clean install but the problem has reappeared after a few days/weeks.
At some point, servermgrd was crashing with a message about NSURL.... (lost and forgot the exact message).
-Tried to remove all the files in /private/var/servermgrd/
This solved the crashes but it now runs without opening the ports. After starting, it doesn't run away and consume any CPU.
Could not locate in system.log, console.log and servermgr.log any error messages indicatind something is wrong with servermgrd.
The log does show that server names are coherent.
Apr 18 23:06:31 server-1 servermgrd: servermgr_dns: hostname and DNS entries for this server are synchronized
- Tried rebooting.
- Tried running servermgrd with various flags, including alternate port but nothing happen. In fact the alternate ports do noot seem to get open. Even passing faulty options, it runs without complaining !
- Tried to reinstall the admin tools
- Tried to remove keychain paswords entries
- Tried Disk Utilities repair permissions.
Searching the posts, found somebody talkingabout servermgr_ctl
I'm starting to suspect some hardware failure (RAM).
Any suggestion how to test the ram.
Running out of idea.
Desperate for solution.
Background
OS X Server 10.4.9
Server Admin version Version 10.4.7 (157.8)
Xserve Dual G4 with 2 GB ram. Mac OS X (10.4.9)Ok, I ran memtest 4.2 and discovered the ram was failing, In replacing the dimm, they started working again so it may have been a mis-seated dimm module or some oxidation on the contact. My file system was already corrupt despite it being a fresh install. Then I checked and notice that the file com.apple.servermgrd.plist in Library preferences was gone. Either I stuppidly deleted it trying to fix the problem or it was hosed by the memory/file system corruption. Anyway, I copied it from another server and Both Server Admin and Server Monitor are now working.
SOLVED.
PS: in view of this event, once I'm satisfied the memory issues is solved, I'll do again a clean install. Who know what else was corrupted. -
Open Connection to SQL Server 2000 Instances
Dear All:
I always got following error when connecting to a SQL Server 2000 instance:
"Can't open a socket on NAMNGO\RNDSQLSVR:1433. Check host and port number and
make sure the
security manager allows this connection. You can also try running the SocketApplet
(java.net.UnknownHostException:
NAMNGO\RNDSQLSVR)"
I am using Wel Logic 6.1 and SQL Server 2000. SQL Server 2000 has an instance
named RNDSQLSVR with default TCP port is 1433.
Is there anyone hit this problem, please let me know.
Please check the attached file for sample code.
Thanks,
Nam Ngo
[att1.html]Hi Sree,
Thank you for your help. It worked.

Hi Nam,
The way you do this is by finding out on what port the instance of SQL
Server you want to connect is listening on. (Use the server network utility
that comes with SQL Server 2000 for this). Then just mention the
server=<machine name/ip> of the server this instance is running on. and
the
port as the port that is shown by the server network utility as port=<port
number>. Microsoft specifies NAMNGO\RNDSQLSVR:1433 as the convention
for
ODBC but , this driver is a type 4 driver and it needs only the machine
name
and port, it doesnt need any instance name.
(Each instance of SQL Server 2000 listens at a different port)

Cannot open connection to dvsrv1: The Synch Manager component on the server
Hi Experts,
I extracted batabase for the mobile client successfully, but when trying to initialize the lcal database, Getting the following error:
Unable to Connect to server>
<Cannot open connection to dbsrvr1. The Synch Manager component on the server is most likely unavailable.>
<Internal: connect() failed: Connection timed out.>
I do not have port number mentioned over here as this installation is in my personal laptop.
As I understnd all the ODBC connections are working fine. It would be great if get here some suggestion to do some extra check if required.
In my system DSN in ODBC I could see number of DSN have been present, one for local DBF, one for sample, one for server which I belive I created during the DBserver configuration as external. and could fine one more DSN not sure what for it is.
If the ODBC would not have been configured properly then I belive I should not be get connected to application through thin and thick client.
Any suggestion on this would be helpful
Thanks
DeepakHI Deepak,
I have seen a similar problem back here there are two locations in your tools.cfrg where you may will need to make changes.
1.
[InfraObjMgr]
RequestServerName =
2.
[Local]
DockConnString =
In both the cases you need to mention the Application server name .
Kindly let me know if this actully solves your issue.
Thanks
