RE: will there be locking on oracle database files in the filer?"
by Chetrit Marc 18 Jun '01

18 Jun '01

We use a similar configuration with HP servers (3 machines in an MC/ServiceGuard cluster), and I can say that ORACLE locks database and control files, so I don't think it's possible that 2 different machines open the same database. BUT, one problem we get is that : - When a node running ORACLE database is down (hardware problem for example), files stay locked - It's then impossible to start the same database on an other node. The only standard issue is to restart the first node so that locks are free (but this issue is not availabe if the node has a real hardware problem!!!) The only issue we got to solve that is to use a NETAPP undocumented command that releases all locks. _______________________________________________ Marc Chetrit SIEMENS AUTOMOTIVE SA SASAOI ITS Back Office BP 1149 Avenue du Mirail Phone : 33 (5) 6119 8421 31036 Toulouse Cedex France Fax : 33 (5) 6119 2515 mailto:marc.chetrit@at.siemens.fr <mailto:marc.chetrit@at.siemens.fr> -----Original Message----- From: Link, Bill (OTS-EDH) [mailto:Bill_Link@billing.com] Sent: vendredi 15 juin 2001 21:34 To: 'luis santos'; toasters(a)mathworks.com Subject: RE: will there be locking on oracle database files in the filer?"

legato netapp client
by Peter D. Gray 18 Jun '01

18 Jun '01

It seems most people on this list are using NDMP for backup of their filers. However, I would like to avoid that if I can. Does anybody have expereience with the legato netapp client and does anybody know if that product is being maintained into the future? Regards, pdg -- See mail headers for contact information.

RE: NOW software downloads

Todd, Here is the remaining answer from Renee La Londe (e-Services): "Our legal department won't let us get around enforcing the acceptance of the license. But we can put the continue buttons somewhere on the top and not make "hidden" where you have to scroll down. Great feedback and we will look into that pronto."

Todd, The intent of the metrics is to show current FCS and GA releases for the purpose of making informed upgrade decisions. We decided not to show old releases because we felt they were largely irrelevant in the decision to upgrade. The 6.0x and above metrics that you're seeing are based on the platform you are selecting for upgrade. If you select F500 series platform for example, you'll see the release metrics for 5.3.7. If you go to the "Bugs Online" page, you can see all metrics for all FCS and GA releases on one page, regardless of platform using the "Release Metrics" tool. Thanks for the comments on the tool - much appreciated. Rod Bagg Director, Sustaining Engineering Network Appliance rbagg(a)netapp.com 408-822-6042 (voice) 408-994-2696 (pager) 408-205-9533 (cell)

CIFS issues when upgrading to 6.X
by Lance R Bailey 15 Jun '01

15 Jun '01

i'm upgrading our NFS based 760 cluster to 61R1. easy enough, i've done that before. our NT team has asked that i upgrade their shiny new 760 CIFS based machine to 61R1 at the same time. i plan to do it using the same procedure, but am wondering if there are any CIFS-based gotchas. i am not a cifs-friendly person, so this is pretty much black art and our NT team is still pretty new to netapps. sort of the blind in one eye leading the blind in the other eye. this will be during a scheduled outage, so losing CIFS connexions due to reboots is not an issue. thanks -- email: lance_bailey(a)pmc-sierra.com box: Lance R.

NOW software downloads
by Todd C. Merrill 15 Jun '01

15 Jun '01

Ho-ray: Was just downloading some software from NOW.... Hey, there are these neat "metrics" on one of the pages. Cool! How about adding older releases, please? Only 6.0.x and higher are listed. Gripe: And, why when I'm downloading the software do I need to read a full page or two of licensing before clicking "accept." You know who I am, the cookies are enabled; yes, of course I accept. Declining just brings me back to the intermidably long features/limitations/bugs/doc/upgrade page anyway. Clever, the way the "continue" button to actually *download* the software is hidden way at the bottom... I assume all this information is contained in what I'm downloading, yes? Until next time...

/etc/rmtab [was: re: showmount?]

I'm keeping an eye > on it now and will find out in due course ... :) My best fit to the observations is that a new clean /etc/rmtab is written when the proportion of non-cancelled entries in the old one falls to 10.5%. [The critical proportion is definitely more than 1/10 and definitely less than 1/9.] > The problem that obsolete entries not explicitly cancelled by client action > never go away definitely still exists, though. Indeed, it seems that in some ways it may be worse. One used to be able to sneakily cancel dross by writing judicious "#"s to /etc/rmtab oneself, and after the next reboot they would be gone. Now such trickery is lost each time a new /etc/rmtab is created from (presumably) the in-store active list. The na_rmtab(5) man page in 6.1R1 still says that /etc/rmtab "may be removed before rebooting the server" to get rid of such things, but I wonder whether it now has to be *just* before rebooting, in case the file should reappear!
