you should update to 8.5.2 FP1

Notes and Domino 8.5.2 FP1 has been released last Friday. It took a while until all binaries occurred at fix central.

FP1 has a couple of important fixes on the server side. You should really consider to upgrade your servers if you are running on 8.5.2.

On client side now attachment icons on Win7 64bit look OK again. Before you could get odd icons when you attach a file.

Daniel, do you know if also the win2k8 problem is fixed in this FP of which you have blogged beginning of october?

@Matthias,

yes the SPR to have the random mode disabled is included in 8.5.2 FP1.

we finally convinced IBM to get it included. the default is still that the random mode is still enabled.

the fix was a late fix that made it into FP1 and the update in the fixlist db has been made shortly before FP1 was available

SPR# KBRN899NF6 - Fixed a problem where setting Disable_Random_RW_File_ATTR=1 in the notes.ini does not disable setting RANDOM RW file flag.

You may also apply this OS fix:

@Christian,

this fix might not be needed when applying the IBM fix. but on the other side it should not harm.

I have tested with and without the MS fix and it turns out that the main issue is how the cache manager works when random read flag is set.

In our customer situation we have been using Win2008 R1 which needed a different MS hotfix. And in my tests I used both R1 and R2 with the corresponding hotfixes.

We had one customer who had shutdown performance issues which have been solved by applying the IBM fix.

There is a IBM technote referencing the two MS fixes (for R1 and R2)

http://www.ibm.com/support/docview.wss?uid=swg21427348

Even with those hotfixes we have performance issues. The cache manager design is not really what I would expect from a cache manager and used with random optimized operations in the way Microsoft implements it does not work for Domino at all.

So the solution is to avoid those kind of operation and use the fix from IBM side to introduce the notes.ini parameter to disable the random flag.

I have spend days tracing this problem with all the various settings and hotfixes.

We had an escalation going on at Tivoli, Lotus and Microsoft and it finally turned out that the only complete solution was to disable the random mode.

Thx Daniel for details. My post was meant as supplemental, because the IBM fix only applies to Domino.

BTW, do you know if the fix is honored by the Notes client, too?

I have large XenApp/Terminal/RDS servers in mind, where users are working with large databases, too.

@Christian,

I am not sure if this variable is also fixed on the client side.

For smaller databases it would be OK or could even better from performance if the database is allocated in cache if you have a lot of RAM available on 64bit.

But you are right for Citrix this might be a different case and could change the performance.

We both know that running larger databases locally on a Citrix server is not a good idea at all.

I would only allow the normal personal databases a uses needs on a Citrix server.

Peter had to build an Extension-Manager for a customer to not allow that user create own databases when they are running on Citrix for this and other reasons.

I agree that setting the parameter would make sense in any case on Citrix but large DBs should be avoided too ;-)

Let me check what I can find out about if the parameter would work on a client too.

@ Christian

Update. according feedback I got from IBM the notes.ini parameter also works on client.

the current plan is to disable RANDOM read in 8.5.3 but it is not confirmed yet.

Let me know what you find out about performance changes.

Thx for your efforts, Daniel :-)

As I am not very active in the XenApp/TS/RDS area recently, I am afraid to owe you the stats.
