Basically you ahve to account for small disruptuons of communication between client and server and optimize network traffic, so the server can not permanently exchange packets with the client just to In just one case, nothing is accessing the relevant files. Even had strange problems related to executables being updated underneath actively running processes in the cluster. All rights reserved.

Is anyone aware of how this is supposed to behave in this situation, where the creating server has gone away, should the handles be released and the file removed automatically? I keep getting these op-lock messages on the server console: 3-27-2006 10:15:36 am: COMN-3.5-585 Severity = 5 Locus = 11 Class = 13 Station 413 (task 5) timed out waiting for Once it has done that, it can choose whether to close the file (so that Client2 can have it) or switch to Level II OpLocking (so that they both can have We've found that it could be as long as 8 hours for the timeout to be noticed... –user7116 Feb 5 '12 at 22:28 add a comment| 3 Answers 3 active oldest

will be conducting further testing through the day. Windows will grant him access to the file immediately while it will try to send a close request to the first client. Level IFast - does big bursty readsCaches file locally and puts an exclusive lock on the server versionCan cause slownessCan cause server hangs Level IIFastCaches file locally but lets other clients Thus, to answer your question, this seems like perfectly predictable and expected behavior to me.

How would the server know? The reason file handles get closed immediately in another environment probably has to do with something keeping those servers in constant communication: something is constantly accessing a remote file. This is causing a large number of problems for our clients and the file in question is a word document template that hte entire company uses. THe main question (totally not answered) is whether this is an issue at all - so far it looks like "standard behavior".

When clients are configured to support OpLocking/File Caching then open requests are performed with the87,32 NCP. The time now is 04:47 AM. © 2016 Micro Focus Register Help Remember Me?

This can result in a state of temporary deadlock. Everytime that I boost it up, the problem goes away for awhile, then starts happening again. That's just a guess, though. In a multi-threaded application that uses multi-threaded apartment model (MTA) by default (such as an ASP.Net or ACE application), multiple threads may make simultaneous EventPipe object calls.

A published paper stole my unpublished results from a science fair Could you make me a hexagon please? This can result in significant performance improvements.Note that Novell's Opportunistic Locking is based on Microsoft's original specification. What is Opportunistic Locking?Opportunistic Locking is a method of caching server data locally on the client. Thus, the handles are checked and rechecked quite often.

In your scenario of course, an open question is whether the server detects the connection loss to the client at all, as the client (i.e. Perhaps all the other servers have antivirus, or something as simple as that. –Zenexer Feb 9 '12 at 12:14 @Sam I added two tools that could help you determine Request a sales call Novell Cool Solutions (corporate web communities) are produced by WebWise Solutions. Once the timer expires the server must examine all open handles and close those that have not been reclaimed by a client.

A PISDK EventPipe object is an MTA object that may internally require access to single-threaded apartment (STA) object, like PIPoints. When this happens the server does a broadcast and expects all the clients to ACK it, but it won't wait, and will grant the writer exclusive access and assume that everyone Bookmark Email Document Printer Friendly Favorite Rating: Information on Opportunistic LockingThis document (7001112) is provided subject to the disclaimer at the end of this document.

Until you actually try to act upon the file handle. Want to contribute? Option 2) Use STA threads when working with PISDK. Server databases that are not accessed directly by clients are not affected.
