RE: OSSV SnapVault
by Garavito, Donald, CTR, OSD-ATL 02 Dec '04

There is a semi-hidden para at the end of the SnapVault Deployment and Configuration Tech Report TR-3240 addressing databases (quoted below). This addresses what to do after you have already created the initialized base 0 transfer. We are testing this now using Solaris/Oracle/R150. Don ============================================================================ ==================== 4.5. Special Case: Databases and Application Server Backups Simply scheduling a Snapshot on a database volume may not create a safe, consistent image of the database. Most databases can be backed up while they continue to run and provide service, but must first be put into a special hot backup mode. Other databases need to be quiesced (which means that they momentarily stop providing service) and some need to be shut down completely, enabling a cold backup. In any of these cases, you must take certain actions before and after the Snapshot is created on the database volume. Since these are the same steps you should take for any other backup method, your database administrators probably already have scripts that perform these functions. While one could set up SnapVault Snapshot schedules on such a volume and simply coordinate the appropriate database actions by synchronizing the clocks on the filer and database server, it is easier to detect potential problems if the database backup script creates the Snapshots using the snapvault snap create command. In this example, we want to take a consistent image of the database every four hours, keeping the most recent day's worth of Snapshots (six copies), and we want to retain one version per day for a week. On the SnapVault secondary, we will keep even more versions. The first step is to tell SnapVault the names of the Snapshots to use and how many Snapshots to keep. No schedule should be specified because all Snapshot creations will be controlled by the database backup script. * toaster> snapvault snap sched oracle sv_hourly 5@- This schedule takes a Snapshot called sv_hourly, and retains the most recent six copies, but does not specify when to take the Snapshots. * toaster> snapvault snap sched oracle sv_daily 1@- This schedule takes a Snapshot called sv_daily, and retains only the most recent copy. It does not specify when to take the Snapshot. * toaster> snapvault snap sched oracle sv_weekly 1@- This schedule takes a Snapshot called sv_weekly, and retains only the most recent copy. It does not specify when to take the Snapshot. Once this has been done, you must write the database backup script. In most cases, it will have the following structure: [ first commands to put the database into backup mode ] rsh toaster snapvault snap create oracle sv_hourly [ end with commands to take the database out of backup mode ] You would then use a scheduling application (such as cron on UNIX(r) systems or the Windows Task Scheduler program) to take an sv_hourly Snapshot each day at every hour other than at 11 p.m. A single sv_daily Snapshot would be taken each day at 11 p.m., except on Sunday evenings when an sv_weekly Snapshot would be taken instead. In most cases, it is entirely practical to run such a database backup script every hour because the database only needs to be in backup mode for a few seconds while the script creates the Snapshot. ============================================================================ ====================== -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Sto Rage(c) Sent: Wednesday, December 01, 2004 8:48 PM To: Alec Devroey Cc: toasters(a)mathworks.com Subject: Re: OSSV SnapVault We have been using OSSV for a while for both Windows and Unix, but not for any Databases yet.

Has anyone used OSSV SnapVault to backup data from Windows, Unix, Linux and Sco. How does it handle Database files like * Oracle - What needs to happen to the Database file before it is transmitted, and what is transmitted from the Server to the Filer Changes or whole database? * SQL - What needs to happen to the Database file before it is transmitted, and what is transmitted from the Server to the Filer ? * Informix -What needs to happen to the Database file before it is transmitted, and what is transmitted from the Server to the Filer ? * Lotus Notes - What needs to happen to the Database file before it is transmitted, and what is transmitted from the Server to the Filer ?

experiences with a FAS270c?
by Kelsey Cummings 02 Dec '04

02 Dec '04

I'm considering purchasing a FAS270c and I'm wondering if anyone has any experiences with them to share. I've worked with NetApps for a long time -- the first was a f230 -- and they've never let me down so I don't expect less from the FAS2xx series. -k

RE: Simulation jobs peaking filer CPU & CP

Sounds like the NFS ops your LSF cluster generate may simply be overloading your 960 ... Have you tried any filers other than the 960? The 980 filer has SPEC sfs numbers more than 40% faster than the 960. If you really need high-performance try a filer even faster than a 980. On Spec.org you'll find the Spec numbers for the Titan filer, which delivers more than twice the spec. ops of a 960 filer and is almost 40% faster than a 980. That would probably help handle any LSF cluster load for a while. http://www.spec.org/sfs97r1/results/sfs97r1.html Published Spec results - single head 960 25135 980 36063 Titan 50858 Published Cluster Spec. results 960c 48143 980c 68139 Titanc 101571 http://www.marketwire.com/mw/release_html_b1?release_id=75166 If you don't get a faster filer, the other option is to break-up the jobs into smaller parts. Let me know what you end up doing ... could be useful and interesting. Cheers Frank Patterson "Everything should be made as simple as possible, but not simpler."

Dear Friend
by bellikatu＠gemari.or.id 01 Dec '04

01 Dec '04

Hello Friend, I wrote this letter as confidential one to you, please kindly read it carefully and send a reply to me. My name is Mrs Bellinda Katumura, former director of finance in the campaign team of Ex. President D Ratsiraka, of Republic of Madagascar, an island in the Indian ocean. I worked with him for years until he was ousted with violent protest by the opposition, and he went into exile in France. This protest erupted during the election period, it was bloody that several people died including my husband. Since the opposition took power in Feb 2001, many of us who served in the regime of the former president have been subjected to several intimidation and detentions, as am writing you now we have not totally regained our freedom. I have one thing that disturbs me. In the last days of the ex-president he took all the monies for the election along with him to exile. The one in my custody was properly hidden by myself, and I told him (the ex president) that it was gutted by fire in my office set by mobs of the opposition. Truely the office was razed down beyond recognition by fire, it is a fact he knows therefore no questions to answer. Immediately he left and the tensed atmophere beclouding our nation there was rush of foreign nationals leaving our country with their families and belongings for safety, under that cover I was able to send out the amount left in my custody to a country in europe through cargo, the consignment was disguised as personal effect. The amount involved is ( $16,000,000=) sixteen million dollars cash. I have contacted the company and they aknowledge receipt of the consignment they have also informed me to come forward for collection. I did not inform them that my freedom in my country is not total. I am not permitted yet to travel out of my country. I need somebody, who understands my situation to travel to the country in europe where the consignment was sent, with the informations I will pass on to him, to stand as my partner/beneficiary and took delivery of the consignment and lodge it into his account for safety. I write this letter to you, to seek your assistance in this issue, we shall discuss other informations as soon as you declare interest to assist me. All required information will be passed to you including the company name and the name of the country where the consignment is. If you have any question pls ask me. Expecting your reply soonest. Also treat as Highly Confidential. Yours Truely. Mrs. Bellinda Katumura. Antananarivo.

80K is a lot of NFS ops to say the least. I wasn't awareYou may be at the limits of the device, but we won't know for sure until we see a few statistics. Questions; What is disk utilization during this period? I assume your sysstat is indicating at least one disk is at 100% What size raid groups do you have on your volumes? Please capture a statit output? Rsh <filer> "priv set advanced;statit -b" , leave for a period while the utilization is known to be high. Rsh <filer> "priv set advanced;statit -e" > output.log (capturing output to a file). Let have a look at that output and see if you are bound on one or a few disks in a raid group, or whether you are just asking too much of the filer. There are a few other things in the statit that will be useful. You may have to look at splitting the workload across volumes or even into other filers. --Aaron -----Original Message----- From: cisco joe [mailto:ciscojoe305@yahoo.com] Sent: Tuesday, 30 November 2004 2:45 AM To: toasters(a)mathworks.com Subject: Simulation jobs peaking filer CPU & CP All, We have some issues with LSF simulation jobs writing to filers(FAS960) ..
