• Spots appear in a rectangle area on screen, ubuntu gnome 13.04, nvidia driver

  - by frozen-flame

  I am using Ubuntu Gnome 13.04 with nvidia-310 driver installed. My GPU is GeForce GTX650. Strange spots freqently appear on screen, with following traits: Spots are restricted in one or two rectangle areas at any instant. When typing, the pattern of spots change. Possibly increase, or all disappear when one key pressed. Mouse movement also influences. This problem last within one boot. The only way can I get rid of this problem is to reboot. It can be detected as soon as entering desktop if it appears. Simultaneously, the "power off" option is lost in the top-right menu of Gnome3. Never such problem when using windows 7 on the same computer, neither ubuntu with Nouveou driver. Seldomly, half of the screen become black. I googled a lot. Similar conditions are described, but no confirmed solution. Uninstall-r einstall strategy does not work. Any clue solving this will be appeciated.

• Ubuntu lucid, maverick high iowait

  - by netom

  I'm using Ubuntu, and I've got the same problem with Lucid and Maverick. From time to time, especially a few minutes after boot, the iowait goes between 50-100% and the box is unusable. Everything that tries to access the disk freezes. I have the following setup: Hard disk: Model Family: Western Digital Caviar Green family Device Model: WDC WD15EADS-00P8B0 Serial Number: WD-WMAVU0391287 Firmware Version: 01.00A01 User Capacity: 1.500.301.910.016 bytes I have a quad core Intel Core2 Q6600 processor, and 4G of memory. When the high iowait occurs, usually 4 processes are active: kdmflush (two procs) jbd2/dm-0-8 jbd2/db-1-8 and a few more starving user processes of course. I know this from top and iotop. Any suggestions about why this is happening? There are a lot of q/a-s about linux and high iowait, but none of them helped so far, I even tweaked the hard disk not to park the head in every 8 seconds (Load cycle count is 50334!!!!! :o ), but nothing. Problem persists. Thank you in advance.

• CentOS - mdadm raid1 drive won't mount to default location

  - by danny

  I'm running CentOS 5.5, the system, boot, swap, etc. is all on /dev/sda and I have two identical single-partition drives /dev/sdb1 /dev/sdc1 that are configured in RAID1 (using mdadm). It was working fine (configured to mount to /mnt/data in the fstab file) and I recently let yum install a couple of automatic updates without paying attention to what they were, and now it doesn't work. Raid is working fine (dmesg shows it gets loaded correctly). mdstat shows: # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdc1[1] sdb1[0] XXXX blocks [2/2] [UU] unused devices: <none> Additionally, I can mount it anywhere other than its default directory (i.e. the following works, and I can read data off the drives). # mount /dev/md0 /mnt/data2 EXT3-fs warning: mounting fs with errors, running e2fsck is recommended But when I run the following I get: # mount -a mount: /dev/sdb1 already mounted or /mnt/data busy It says nothing is mounted when I try to umount /dev/sdb1 or umount /mnt/data, so I assume it's the second of those errors. However, lsof | grep mnt shows nothing. The weird thing is that I can save files in /mnt/data. So something is obviously mounted there, but when I try to umount it I get the error that nothing is mounted. /etc/mtab doesn't mention any of the partitions or files I am trying to work with, and fstab just has that one line I mentioned above that is supposed to mount my raid partition. Again, it was all working fine until I On Google I've found a few things about dmraid interfering with mdadm after an update, but I yum remove'd dmraid and rebooted and it didn't help. I'm really confused and need to get this working to get on with my work!

• Sonicwall TZ210 - Set up public wifi on separate subnet & interface

  - by thomasjbarrett

  I want to set up a public wifi by connecting another router to the X6 interface, and put it on a separate subnet (192.168.10.0/24) & in the DMZ Zone to keep it away from the regular LAN. I believe I have the network settings correct: the router has acquired the IP and DNS information from the TZ210, and the TZ210 shows it as an active DHCP lease. X6 is in the DMZ. I now have a routing/NAT/firewall problem, since I can't get any traffic to travel from the subnet to the internet. I can't get to any external websites and can't ping the TZ210 from the subnet. X0 is the regular LAN, and X1 is the WAN. Looking for any tips or tutorials on this. Here's my current relevant rules: Routing Source: X6 Subnet Destination: Any Service: Any Gateway: Default Gateway Interface: X6 Source: Any Destination: X6 Subnet Service: Any Gateway: 0.0.0.0 Interface: X6 NAT Policies Source Original: Any Translated: WAN IP Destination Original: Any Translated: Original Inbound: X6 Outbound: X1 Source Original: Any Translated: U0 IP Destination Original: Any Translated: Original Inbound: X6 Outbound: U0 Firewall DMZ LAN : Deny All DMZ WAN : Allow All LAN DMZ : Allow All WAN DMZ : Allow All

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• Subversion Edge LDAP (require CAC Certificate not Username and Password)

  - by Frank Hale

  What I've Done: I've successfully installed and configured Subversion Edge 3.1.2 with LDAP support on a Windows 2008 server. I have configured LDAP users and am able to use LDAP credentials to work on repositories just fine. No issues whatsoever. Works great! What I Want To Do: I've been searching for several hours now in hopes to find some information on how to configure Subversion Edge server to require client certificates for user authentication against an LDAP environment. I have not found anything yet that gives me an indication of how to do it. I know there are SVN clients that are capable of prompting for CAC certificates but I cannot figure out how to set my server up to require it. NOTE: CAC authentication is already setup and working in the windows environment. Desired Outcome: When running svn commands that require authentication against my Subversion Edge Server I want it to prompt me for my CAC certificate instead of my Active Directory username and password. If anyone has any information on this I'd greatly appreciate it. EDIT: I'm still digging so if I find out anything I'll update this question with what I found.

• ASA Slow IPSec Performance with Inconsistent Window Size

  - by Brent

  I have a IPSec link between two sites over ASA 5520s running 8.4(3) and I am getting extremely poor performance when traffic passes over the IPSec VPN. CPU on the devices is ~13%, Memory at 408 MB, and active VPN sessions 2. The load on both of the the devices is particularly low. Latency between the two sites is ~40ms. Screenshot of wireshark file transfer between the two hosts over the firewall IPSec VPN performing at 10MBPS. Note the changing window size. http://imgur.com/wGTB8Cr Screenshot of wireshark file transfer between the two hosts over the firewall not going over IPSec performing at 55MBPS. Constant window size. http://imgur.com/EU23W1e I'm showing an inconsistent window size when transferring over the IPSec VPN ranging in 46,796 to 65535. When performing at 55+MBPS, the window size is consistently 65,535. Does this show a problem in my configuration of the IPSec VPN in the ASA or a Layer1/2 issue? Using ping xxxxxx -f -l I finally get a non-fragment at 1418 bytes so 1418+28 for IP/ICMP headers = 1446. I know that I have 1500 set on the ASA and Ethernet. I do have "Force Maximum segment size for TCP proxy connection to be" "1380" bytes set under Configuration Advanced TCP Options on the ASA. Using IPERF, I am getting a "TCP Window Full" every few seconds and ~3 MBPS performance. http://imgur.com/elRlMpY Show Run on the ASA http://pastebin.com/uKM4Jh76 Show cry accelerator stats http://pastebin.com/xQahnqK3

• Using IIS7 as a reverse proxy

  - by Eric Petroelje

  I'm setting up a server at home to host a few small websites. One of them is .NET based and needs IIS, the others are PHP based and need Apache. So, I have both IIS 7 and Apache 2.2.x installed on my server with IIS on port 80 and Apache running on port 8080. I would like to set up IIS to work as a reverse proxy, forwarding the requests for the Apache sites to port 8080 and serving the requests for the .NET site itself based on the host headers. Like this: www.mydotnetsite.com/* -> IIS -> serve from IIS www.myapachesite.com/* -> IIS -> forward to apache on port 8080 www.myothersite.com/* -> IIS -> forward to apache on port 8080 I did a bit of googling and it seemed like the Application Request Routing feature would do what I needed, but I can't seem to get it to work the way I want it to. I can get it to forward ALL traffic to the Apache server and I can get it to forward traffic with a specific URL pattern to the Apache server, but I can't seem to get it to forward based on the host headers (e.g. "forward all requests for www.apachesite.com - localhost:8080") So the question is, how would I go about configuring ARR to do this? Or do I need a different tool? I'm also open to using Apache as the reverse proxy and forwarding the .NET site requests to IIS instead if that's easier (running Apache on port 80 and IIS on 8080).

• 8007064c(2011) and 80280007(2009) persistant after all known repairs

  - by tiu44

  I'm on Windows 7 Home x64, and have ran into a major issue with Live Messenger(which I use daily). I have full offline installers for both 2011 and the last Wave 3 2009(14.0.8117.0416) Suites. Both give the following errors: Live Essentials 2011 Offline installer(official): An unknown error occured. Error:0x8007064c Source WLXSuite WL 2009 offline installer(official): You already have a more recent version of Windows Live. Error: OnCatalogResult:0x80280007 Next steps: If you want to install this older version, first uninstall any later versions that are on your computer. Get help with this error The 2011 installer also says it is updating messenger, I don't select anything else. Then last 2009 installer says their is a newer version that needs uninstalled even after the following procedures. MS Help pages provided all basically lead to using uninstall from control panel. Which I've uninstalled all Live components including watcom safety scanner and portable SQL from. I've followed online instructions for manually deleting folders from Program Files(x86), Appdata, and some others under \User\All Users and the one for the one account on the machine. I've used CCcleaner 3.01, ASC 3.7.3 and Beta 4 with deep scan along with deleting folders, and checked their uninstallers for Live components too, and none were there. wlmuninstaller.exe tool reports nothing, but after a failed install it finds something, but failes to clean it under all user admin privilege. The same errors still occur after all of that. Google searching I see people on forums suggesting reinstalling the OS cause MS doesn't even know how to fix this, but I'm hoping someone here can help. NOTE: I don't have System Restore or any other state freeze utilities going, and I don't have any real time AV going(I sometime scan with defender, anti rootkits, and online scanners). NOTE2:I posted this on windowslivehelp.com, before looking to see if the place was active or not, hoping I can get help here. Thanks

• Architecture for highly available MySQL with automatic failover in physically diverse locations

  - by Warner

  I have been researching high availability (HA) solutions for MySQL between data centers. For servers located in the same physical environment, I have preferred dual master with heartbeat (floating VIP) using an active passive approach. The heartbeat is over both a serial connection as well as an ethernet connection. Ultimately, my goal is to maintain this same level of availability but between data centers. I want to dynamically failover between both data centers without manual intervention and still maintain data integrity. There would be BGP on top. Web clusters in both locations, which would have the potential to route to the databases between both sides. If the Internet connection went down on site 1, clients would route through site 2, to the Web cluster, and then to the database in site 1 if the link between both sites is still up. With this scenario, due to the lack of physical link (serial) there is a more likely chance of split brain. If the WAN went down between both sites, the VIP would end up on both sites, where a variety of unpleasant scenarios could introduce desync. Another potential issue I see is difficulty scaling this infrastructure to a third data center in the future. The network layer is not a focus. The architecture is flexible at this stage. Again, my focus is a solution for maintaining data integrity as well as automatic failover with the MySQL databases. I would likely design the rest around this. Can you recommend a proven solution for MySQL HA between two physically diverse sites? Thank you for taking the time to read this. I look forward to reading your recommendations.

• Apache Process question about RAM usage

  - by Andrew Fashion

  So everytime I load a new page, I notice a new HTTPD process opens, every time I click a page, and each process says it's using anywhere from 2-4.5% of memory. Does that mean every single process is running at that time using 2-4% of RAM? It's a brand new server and I'm the only one on the server at the moment. Or does it mean all the other processes are dying, and only the new one is active. Because 4% of my 2048MB of RAM is already 82MB for just one process!?!? Let me know, because I am trying to determine what I need to beef my server up in order to handle high loads of traffic. I'm expect to get 20,000 uniques per day on launch. I am currently running a Dual Quad Xeon server, with only 2GB of ram, I will upgrade to 8GB or more shortly. Let me know what you suggest! thank you [root@D18634 log]# top | grep 'httpd' 11315 apache 15 0 362m 82m 24m R 12.3 4.1 0:03.00 httpd 11310 apache 16 0 322m 41m 21m S 5.7 2.1 0:02.98 httpd 11315 apache 15 0 362m 83m 25m S 24.3 4.1 0:03.73 httpd 11319 apache 16 0 324m 42m 20m R 1.0 2.1 0:01.85 httpd 11319 apache 16 0 362m 82m 23m R 78.5 4.1 0:04.21 httpd 11321 apache 16 0 323m 44m 23m S 35.3 2.2 0:04.13 httpd 11319 apache 15 0 361m 82m 23m S 8.3 4.1 0:04.46 httpd 11321 apache 15 0 323m 44m 23m S 35.9 2.2 0:05.21 httpd 11313 apache 15 0 324m 41m 19m S 48.6 2.1 0:03.23 httpd 11322 apache 16 0 354m 72m 20m R 11.0 3.6 0:05.11 httpd 11322 apache 16 0 354m 72m 20m S 23.9 3.6 0:05.83 httpd 11314 apache 16 0 355m 75m 22m R 18.3 3.7 0:04.64 httpd

• Unable to ping domain.local, but can ping server.domain.local

  - by Force Flow

  I have a single windows 2008 server running active directory, group policy, and DNS. DHCP is running from the firewall (this is because there are multiple branch locations, and each location has its own firewall supplying DHCP. But, for this problem, the server and workstation are at the same location). On an XP workstation, if I try to visit \\domain.local or ping domain.local, the workstation can't find it. A ping returns Ping request could not find host domain.local. If I try to visit \\server or \\server.domain.local or ping server or server.domain.local, I'm able to connect normally. If I ping or visit domain.local on the server, I'm able to connect normally. A-Records are in place in the DNS service for server, domain.local, and server.domain.local. A reverse lookup zone also is enabled and PTR records are in place. If I wait 20-30 minutes, I am eventually able to ping and visit domain.local--but, when attempting to ping, it takes 30 second to return an IP address. I am also unable to join a new workstation to the domain during this wait period. If I try, the error message returned is "network path not found". Is there something I'm missing?

• Why do I often have to refresh pages I navigate to once for them (or content in them) to load?

  - by GetOutOfBox

  I have noticed a bizarre pattern when using my PC, that when I open a link to a website, it often will often take a very long time to load, or time out. Sometimes content on the website will be drawn, but again, it seems to get "stuck" for an unusual amount of time before finishing. Most affected is Youtube; almost every time I navigate to a youtube video from another website such as Google, the video will not begin playing, but will instead just display the player controls with a black screen where the video should be and the buffering symbol, usually before displaying an error such as "The video failed to load". The unusual part of this problem is that whenever this happens, refreshing the page always causes it to load almost immediately the second time around, without any problems. Note that I'm not talking about how some browsers will dump whatever has been cached to the "pallet" briefly when the page is refreshed or loading stopped; but that the second time loading the website being faster. I have done my best to rule out some of the obvious causes: My Windows 7 desktop computer is the only device that seems to be affected. I use Firefox on it (latest version, flash updated, etc). My connection has more than enough bandwidth (30 megabits down, 4 up), and I've even tried QoSing all other devices to make sure this isn't happening due to usage spikes. Wireshark is not showing any clearly unusual network activity (i.e frequently dropped packets).

• unable to destroy windows 2008 r2 failover cluster after SAN rebuild

  - by Zack

  I created a windows 2008 r2 failover cluster for a sql 2008 active/passive cluster. This two node cluster was using a SAN device for a quorum disk resource as well as MSDTC resource. Well....I decided to reconfigure the SAN device, but I didn't destroy the cluster first. Now that the quorum disk and mstdc disk are completely gone, the cluster is obviously not working. But, I can't even destroy the cluster and start again. I've tried from the Windows Clustering tool, as well as the command line. I was able to get the cluster service to start using the "/fixquorum" parameter. After doing this I was able to remove the passive node from the cluster, but it wouldn't let me destroy the cluster because the default resource group and msdtc are still attached as resources. I tried to delete these resources from both the GUI tool, as well as command line. It will either freeze for several minutes and crash the program, or once it even BSOD'd the server. Can someone advise on how to destroy this cluster so I can start over?

• Postfix + procmail - delivery fails because "can't create user output file" - on CentOS 6.2

  I verified that my postfix installation / relaying setup worked. Now I am having trouble with procmail. I have it wired to postfix with the following command: mailbox_command = /usr/bin/procmail -f -a "$USER" I have nothing in my procmail config but the following: LOGFILE=/var/procmailrc/log And I send an email to a recipient that previously worked (before I attached procmail).

• MySQL not releasing temp file descriptors

  - by Wakaru44

  Since a few days ago, we’ve been experiencing some serious problems with our MySQL installation: MySQL keeps opening temporal files (normal behaviour) but these files are never released. The consequence is that, eventually, the disk space is exhausted and we have to restart the service and clean up /tmp manually. Using lsof, we see something like this: mysqld 16866 mysql 5u REG 8,3 0 692 /tmp/ibyWJylQ (deleted) mysqld 16866 mysql 6u REG 8,3 0 707 /tmp/ibf5adsT (deleted) mysqld 16866 mysql 7u REG 8,3 0 728 /tmp/ibGjPRyW (deleted) mysqld 16866 mysql 8u REG 8,3 0 5678 /tmp/ibMQDLMZ (deleted) mysqld 16866 mysql 13u REG 8,3 0 5679 /tmp/ibQAnM42 (deleted) Maybe it's not related, but when we shutdown the server, the files are finally freed, and we can see the following warnings in the MySQL log: 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1333 user: 'xxx' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1156 user: 'yyy' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1151 user: 'zzz' where 'xxx', 'yyy' and 'zzz' are distinct mysql users (and the only 3 users with active connections to the database). We have a few theories: There is a problem in the OS, that keeps file handlers open. Could it be possible that the OS "delete" operation blocks the threads until shutdown? This may explain the warning at shutdown and the fact that files are finally deleted when the process dies. Until now, data sets were so small that temp files were relatively small and there was enough time to release the file handles without exhausting disk space. We are using Mysql 5.5 on a RHEL 6.2 with the default kernel.

• Multi-IP address zimbra server DNS PTR records and spam

  - by David Fraser

  We have a mail server running Zimbra (ZCS 6.0.8). The server has 5 active public IP addresses in the same subnet. (.226-.230). I currently have A records for each of these (host0.domain.com..host4.domain.com), with the main host.domain.com of the machine pointing to .226. Our host has ended up being listed on the SORBS DUHL list (even though it's in a server farm). According to them you can get removed quickly by checking that your host has an MX record, an A record, and a PTR record that points back to the hostname given in the MX record. I tried setting the PTR records so that each of these addresses resolved back to their A record (i.e. .228 had a PTR to host2.domain.com). However, I then got mail being rejected from other servers because when Postfix (under Zimbra control) sends out mail, it uses the main hostname for the HELO - there doesn't seem to be any way to override it. So the PTR records currently say host.domain.com for all 5 IP addresses. What's the correct way to handle this? Should I have an A record for the domain that points to all the IP addresses (for round-robin handling)? I'm nervous of changes that could cause problems, so I'm wondering what the standard way to handle a multiple-IP-address mail server is.

• Mac: window manager frozen, have ssh access

  - by Bernd

  I have a Mac which regularly runs into a problem. The user interface stops reponding, showing a "frozen" user interface. The mouse is still moving but clicking does not trigger anything. This happens about once a week. Solution so far is to force switch-off the Mac and reboot it. I have ssh root access to the Mac. Killing (kill -9) the active application has no visible impact on what is shown on the screen. Any ideas on how to diagnose this? Is there a way to restart the window manager from the ssh shell? Killing /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer seems not to be possible. The Mac is an early 2008 iMac and runs Lion with latest updates. /Library/Logs/DiagnosticReports is empty. Update: Problem stays after update to Mountain Lion. The WindowServer process is in "uninterruptible wait" state ("U" flag in ps output set): imac:~ root# ps ax|awk "NR==1|| /WindowServer/"|grep -v awk PID TT STAT TIME COMMAND 86 ?? Us 50:51.69 /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer -daemon Any idea for diagnosing what blocks the process? Any idea for "waking up" the process?

• Cron won't use msmtp to send emails in case of failed cronjob

  - by Glister

  I'm trying to configure a machine so that it will send me an email if one of the cronjobs output something in case of an error. I'm using Debian Wheezy. Cron is working normally (without the email functionality). msmtp is installed and configured. Have already symlinked /usr/{bin|sbin}/sendmail to /usr/bin/msmtp. I can send email by using: echo "test" | mail -s "subject" [email protected] or by executing: echo "test" | /usr/sbin/sendmail Without the symlink (/usr/sbin/sendmail) cron will tell me that: (CRON) info (No MTA installed, discarding output) With the symlinks I get: (root) MAIL (mailed 1 byte of output; but got status 0x004e, #012) Can you suggest how to config the cron/msmtp pair? Thanks! EDIT: Note: I've written "msmtpd" by mistake. Its not a daemon but rather an SMTP client named just "msmtp" (without the "d" ending). It is executed on demand and it is not running in the background all the time. When I try to send an email by using msmtp like that it works: echo "test" | msmtp [email protected] On the far side, in the logs of the SMTP server I read: Nov 2 09:26:10 S01 postfix/smtpd[12728]: connect from unknown[CLIENT_IP] Nov 2 09:26:12 S01 postfix/smtpd[12728]: 532301C318: client=unknown[CLIENT_IP], sasl_method=CRAM-MD5, [email protected] Nov 2 09:26:12 S01 postfix/cleanup[12733]: 532301C318: message-id=<> Nov 2 09:26:12 S01 postfix/qmgr[2404]: 532301C318: from=<[email protected]>, size=191, nrcpt=1 (queue active) Nov 2 09:26:12 S01 postfix/local[12734]: 532301C318: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.62, delays=0.59/0.01/0/0.03, dsn=2.0.0, status=sent (delivered to command: IFS=' ' && exec /usr/bin/procmail -f- || exit 75 #1001) Nov 2 09:26:12 S01 postfix/qmgr[2404]: 532301C318: removed Nov 2 09:26:13 S01 postfix/smtpd[12728]: disconnect from unknown[CLIENT_IP] And the Email is delivered to the target user. So it looks like that the msmtp client is working properly. It has to be something in the cron/msmtp integration, but I have no clue what that thing might be. Can you help me?

If i type this: procmail DEFAULT=/dev/null VERBOSE=yes LOGFILE=/var/log/procmail.log /dev/null </dev/null I get entries in my log file so i know procmail is working Am i doing something wrong? am i missing something? I eventually want my rule to call a php script only if the subject contains "SUPPORT TICKET" and the to is "[email protected]" but that's once i this issue solved.

• JVM system time runs faster than HP UNIX OS system time

  - by winston

  Hello I have the following output from a simple debug jsp: Weblogic Startup Since: Friday, October 19, 2012, 08:36:12 AM Database Current Time: Wednesday, December 12, 2012, 11:43:44 AM Weblogic JVM Current Time: Wednesday, December 12, 2012, 11:45:38 AM Line 1 was a recorded variable during WebLogic webapp startup. Line 2 was output from database query select sysdate from dual; Line 3 was output from java code new Date() I have checked from shell date command that line 2 output conforms with OS time. The output of line 3 was mysterious. I don't know how it comes from Java VM. On another machine with same setting, the same jsp output like this: Weblogic Startup Since: Tuesday, December 11, 2012, 02:29:06 PM Database Current Time: Wednesday, December 12, 2012, 11:51:48 AM Weblogic JVM Current Time: Wednesday, December 12, 2012, 11:51:50 AM Another machine: Weblogic Startup Since: Monday, December 10, 2012, 05:00:34 PM Database Current Time: Wednesday, December 12, 2012, 11:52:03 AM Weblogic JVM Current Time: Wednesday, December 12, 2012, 11:52:07 AM Findings: the pattern shows that the longer Weblogic startup, the larger the discrepancy of OS time with JVM time. Anybody could help on HP JVM? On HP UNIX, NTP was done daily.
