Round-robin Load balancing doesn't work after one instance reboot

Hi,
          We have two weblogic instances in a cluster. All Http requests are routed through the plug-in for load-balancing(round-robin). One instance in a cluster is shutdown for production maintenance. Now all requests are being forwarded to the second instance. When the first instance is started, only the new users are forwarded to the first instance. The requests from users already logged in are not forwarded to the first instance. Due to this the second instance is over-loaded.
          How to prevent this and make weblogic to distribute the load even after the server restart? This is a production problem and I highly appreciate your responses.
          Thanks,
          Prasad Dantuluri

it worked when I removed the value entered in the "Unicast Broadcast Channel" and restarted the cluster. Don't know what is supposed to go in that field but hey.

WAN round-robin load balancing

First things first, I just recently got that horrible distribution Gentoo off my machine and installed Arch for a test run and so far a flipping love it. Just like to thank everyone that made this wonderful piece of Linux.
To the point: I have a box with 3 NIC and it current runs as my LAN gateway. http://pastie.org/608016 is the script I use to do so and as you may have guessed eth0 is my DSL modem eth1 is my LAN switch, eth2 is my cable modem. Currently my LAN runs off just my DSL, if I want to change this and run off the cable I have to change WAN in the script to eth2 and run it. I would like to change this and have it round-robin load balance over my DSL, cable.
I tried
ifconfig eth0 down
ifconfig eth2 down
modprobe bonding mode=0 miimon=100
ifconfig bond0 10.0.0.5
ifenslave bond0 eth0
ifenslave bond0 eth2
inspired by http://ubuntulinuxhelp.com/how-to-use-t … -computer/ and that didn't work at all.
Then I had a look at http://wiki.archlinux.org/index.php/Con … rk#bonding (two ip on two card) but that didn't really make sense to be as you're not specifying what interfaces to bond anywhere.
Could anyone help me?

Let us first set some symbolical names. Let $IF1 be the name of the first interface (if1 in the picture above) and $IF2 the name of the second interface. Then let $IP1 be the IP address associated with $IF1 and $IP2 the IP address associated with $IF2. Next, let $P1 be the IP address of the gateway at Provider 1, and $P2 the IP address of the gateway at provider 2. Finally, let $P1_NET be the IP network $P1 is in, and $P2_NET the IP network $P2 is in.
One creates two additional routing tables, say T1 and T2. These are added in /etc/iproute2/rt_tables. Then you set up routing in these tables as follows:
ip route add $P1_NET dev $IF1 src $IP1 table T1
ip route add default via $P1 table T1
ip route add $P2_NET dev $IF2 src $IP2 table T2
ip route add default via $P2 table T2
What does it mean by 'IP network' ($P*_NET)?

RFC Sender (XI 3.0, SP14) Load Balancing doesn't work

Hi all,
We're "desperately" trying to use the Load Balancing option of RFC Sender Adapter (XI 3.0, SP14). It doesn't work.
The Adapter can not register to the sender SAP server. But when we do not use the "Load Balancing" option, everything works well.
We did follow the XI guidelines step-by-step. All necessary configurations in XI and in SAP sender system (TA: SM59) are "properly" done and reviewed by different experts several times.
Do you have, by chance any running scenario using "Load Balancing" within a RFC Adapter? If yes, I would appreciate if you can share it with me.
Thanks a lot!
Regards,
Khaled

Hello Khaled,
the RFC sender adapter registers a program at the SAP Gateway. Load Balancing for the Sender Adapter means, that you have at least two J2EE server nodes within your XI installation. On all these server nodes the same RFC sender adapter is started and register the same program at the same gateway. The load balancing is then handled by the gateway. That means, that for the sender adapter the settings are the same, even if you use load balancing or not.
The settings are, e.g.
- SID=ABC
- hostname=abchost (central instance, message server)
- hostname=xyzhost (additional dialog instance of ABC)
- instance nr=00
application server (gateway): xi1host
application server service (gw-service): sapgw00
programm id: could be freely choosen
The Metadata Repository could be connected using load balancing. Here a user need to log on to the system.
The settings here must be:
Message-Server: abchost
Message-Server-Service: sapmsABC
System-ID: ABC
Logon-Group: e.g. PUBLIC; this logon group need to be created in system ABC using transaction SMLG
For the RFC-Receiver Adapter the same settings as for the Metadata could be used.
Keep in mind, that for the RFC Sender Adapter a RFC connection of type T must be created in transaction SM59 in system ABC.

Load balancing doesn't work

I'm using iAS 9.0.2.2.1
I need to establish 2 form servers for Load Balancing.
I have done all the things written in the document,
but it seem doesn't work !
I need extra information for establishing Load balancing
in form server , is there anyone could help me !
Thanx in advance
Kamran Bakhshandeh

Hi,
the server version you give is Oracle9iAS Release 2, but the Forms release is Forms 6i as is in Oracle9iAS Release 1 (9.0.1.x). Actually these wont work together. Also, the Forms 6i metrics server used for loadbalancing does not work with Servlets but the Forms listener. Loadbalancing with Forms6i is documented in the Whitepaper for patch 10 (http://otn.oracle.com/products/forms/pdf/p10listenerservlet.pdf).
The load balancing in Oracle9iAS Release 2 Forms Services is done with mod_oc4j.

MPLS TE equal or unequal load balancing doesn't work? - step2

Previous question in thread:
Dear Sir!
I've two MPLS TE tunnels from one PE to another PE.
And there are traffic share count between them
(as tunnel mpls traffic-eng load-share command define).
But in real life all traffic from the same source to the same destination go through only one tunnel
(as CEF define - i.e. how sh ip cef exact-route says).
PEs are 3660 platforms with c3660-jk9o3s-mz.123-8.T
installed.
How can I correct this problem?
But this answer does not solved my issue:
hritter - Network Consulting Engineer, CISCO SYSTEMS, CCIE
Aug 4, 2004, 7:20am PST
This is expected behavior since CEF is used at the head end to perform label imposition. I wouldn't recommend changing the default bahavior to per=packet loadsharing since this could lead to of of sequence packets, which could lower the overall performance.
Hope this helps,
so my secound question:
Dear Sir!
I'm agree with you as MPLS TE tunnels are opened from PE to PE, so CEF does it work.
But if I open this tunnels from P to PE, ONLY ONE of this tunnels are used instead of load-sharing, if traffic go from one source (of site1 of VPN1) to the same destination (located at site2 of VPN1).
Why? Packet through P-devices swithes by labels, so I mean that CEF cannot does src-dst load sharing?
My problem are that I must to do load sharing between this two tunnels in the case above.
Q: How can I solve this problem?
Best regards,
Maxim Denisov

The per session load-balancing is also used by MPLS when multiple paths are available. Changing this behavior to per-packet is still not recommended.
Hope this helps,

Shared public IP with same tcp port (round robin/load balance)

Hi all,
I want to know if I can do that with my ASA5515-X, I have two servers that can do the same thing, there are SSO servers, What I want to do is to publish the 2 servers on Internet with the same public IP address and on TCP 443.
Is it supported ? will it works like load balancing per sessions ?
or do I need to add an HLB between ASA and my SSO servers ?
Thanks

Hi Yann,
You can configure the ASA to allow traffic to your SSO server from outside on two public IP's. Users can hit either of the IP to reach the inside server. Now, load balancing would be achieved based on source devices sending request to public IP's. If source machine son internet use one public IP more to access the server, ASA can't do anything to load balance in such scenario. Here is how you can accomplish this:
Assuming SSO server on inside is 192.168.16.110 and two public IP's are 192.168.17.110 and 192.168.17.111
object network SSO_1
host 192.168.17.110
object network SSO_2
host 192.168.17.111
object network SSO
host 192.168.16.110
object service https

USB HDD 3T doesn't work after one year only

Hello,
I get a external HDD Toshiba from RLO24 i bought the 08.02.20113 and few weeks after it didn't work. No time to contact you and i thought i w'll find a solution to get all my datas back But I lost 3 T of Data? and no way for any computer to recognise my HDD? It seems that it's the physical body is dead? So what can I do?
Thank you to help me out.
Franck
reference P\N HDWC130EW3J1
S\N 5Q080TVW
PLEASE HELP ME

Its pity to hear that the HDD does not work anymore.
The computer could not recognize the external HDD because of two reasons:
1) the HDD controller within in the HDD case has started to malfunction
2) the HDD is faulty.
In 1st case you could try to remove the 3.5 HDD from the case and could try to connect the HDD to another SATA controller just to check if you will get access to the data.
In 2nd case the HDD could no longer be used :(

Accessing individual server in load-balanced cluster not working as expected

We have a cluster set up with multiple managed servers and hardware load
          balancers sitting in front to direct traffic. We have the frontend host
          configured to be the dns name of the single URL for the cluster, which maps
          to the IP address that the load balancers balance. When accessing part of
          our site (a WebLogic portal) at
          http://server1/portalApp/appmanager/portal/desktop
          (where server1 is the name of one of the managed servers)
          the portal performs a redirect to the login page at
          /portalApp/appmanager/portal/desktop?_nfbp=true&_pageLabel=login_page.
          The URL that results in the browser is not what I would expect, which would be
          http://server1/portalApp/...
          Instead, it is
          http://cluster/portalApp/...
          where cluster is the frontend host setting. Is there any way to avoid
          this, so we can perform directed testing on specific managed servers?
          Thanks,
          Andy


Hi Maria, thanks for your help! I wrote a simple test jsp that does a
          redirect if a parameter is set, otherwise it doesn't do anything. When I
          accessed the jsp at server1/app/test.jsp?a=true, something (I assume
          either WebLogic or the load balancer) rewrote the URL after the redirect
          (the redirect was to /app/test.jsp). The URL that appears in the browser
          after the redirect is cluster/app/test.jsp. Do you know if this happens
          because of WebLogic or the load balancer? Our load balancers are Cisco
          11503's I believe.
          Do you think it would make any difference if I leave the frontend host
          for the cluster to be the dns name of the cluster, and then if I set the
          frontend host for each server to be the dns name of that specific server?
          Currently each server does not have any value entered for frontend host.
          Thanks!

Oracle Applications 11i Load Balancing does not work with RAC one Node

Hi all,
Could you help me to resolve this issue.
Architecture environment is :
- One APPS tier node
- Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
- The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
Thank you for your advice.

This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

[Solved] Network doesn't work after hibernate?

Hello! This is my first legit Linux install so excuse me if I'm a bit slow. I installed Arch last night and everything went smoothly. However, after I tested out hibernate on my machine, the network doesn't seem to work. Just prior to the hibernate, I installed Pidgin and Skype but they worked alright, so I think that the hibernate caused a problem on eth0.
I have an Asus P8Z68-V Pro motherboard with an Intel 82579V Gigabit Ethernet Controller that's using the e1000e driver. Running "dmesg | grep e1000e" says that it is up.
I'm not entirely clear here, but from reading, I think that I have several ways of connecting to the network, including network, dhcpcd, networkmanager, and wicd. I am using wicd so I did the following (or at least I think I am only using wicd):
#rc.d stop network
#rc.d stop dhcpcd
#rc.d stop networkmanager
Similarly, I put a ! in front of network in rc.conf:

Restarting eth0 through wicd-cli still did not work. I also tried resuscitating the network via instructions on the configure network page before trying to focus solely on wicd.
I found a few similar problems on the forums by searching "wicd hibernate" and tried several solutions but they did not work. Several problems seem to be that the network doesn't work after a suspend because I guess the stuff in RAM did not get saved? But people were able to restart the network by running "/usr/lib/wicd/autoconnect.py" and I wasn't able to get this to work. As a final effort, I added "resume" into mkinitcpio.conf and placed the machine into sleep again to see if it may magically reset something but of course this did not happen .
mkinitcpio.conf:

Not sure if my fstab.conf is useful but if this has something to do with settings getting "lost" in swap, here it is. Linux is on an SSD and HDD (sda and sdc) and Windows 7 is on a HDD (sdb).

Is wicd causing these problems or did I configure something else improperly? Would appreciate any help to get eth0 up again!

Ok, I think I've made some progress! Hibernate definitely affects my network connection. Could this be a kernel 3.0 problem?
I noticed that ifconfig showed eth0 without an inet addr, just an inet6 addr for the longest time. e1000e seemed to be loading up ok. I'm not certain here, but I think that meant the dhcp settings didn't stick, or something along those lines.
Trying to use dhcpcd like the instructions here did not work. By some chance, one attempt did work and while it did, I downloaded and installed dhclient. After that one successful attempt, renewing the DHCP lease via dhcpcd did not work again.
Luckily though, I found that running "dhclient eth0" worked. My DHCP settings seemed to have somehow gotten messed up after my initial, problematic hibernate to the point where none would stick, even after a reboot. Manually typing in "dhclient eth0" would get eth0 working, so I decided to add it to the bottom of /etc/rc.local, like in the example on the networking page.
Now, eth0 works after a boot. However, after the daemons load up during the boot process, my computer takes a long time to get to the login prompt (this is relatively speaking, since I am on a SSD and the boot process used to be blazing fast before). I'm pretty sure it's because I added "dhclient eth0" to /etc/rc.local.
I should say that even with these changes, after a hibernate, my eth0 still does not work and if it weren't for the edit to /etc/rc.local, eth0's inet settings would still not stick after a reboot (that is to say, the hibernate does do something to my network settings).
Is this the correct/most efficient way to fix my DHCP problem? Can I fix my "eth0 after hibernate" issue? Also, can I make my DHCP settings boot up without changes to /etc/rc.local so that I can get a fast boot again (still not sure how it was able to work before without my edit)?

M3800 Developer Edition: wifi doesn't work after sleep

I have an M3800 Developer Edition (2015 model). Ubuntu is factory-installed 14.04, with hardware enablement stack installed. Recently (past 1-2 weeks) wifi doesn't work after sleep (lid closed or open doesn't matter), and only rebooting gets in back. Tried rmmod and modprobe with no success. Has anyone else seen this, and/or are you aware of any open bug(s) for this?
Relevant ouput:
lsmod when problem exists:
iwlmvm                217725 0
mac80211              652718 1 iwlmvm
iwlwifi               179412 1 iwlmvm
cfg80211              494362 3 iwlwifi,mac80211,iwlmvm
rfkill list when problem exists:

        Soft blocked: no
        Hard blocked: no
3: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
rmmod the above, then modprobe iwlwifi. Does not fix problem, only rebooting does:

Macbook air adoble flash player doesn't work after installation

macbook air adobe flash player doesn't work after installation

If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 7. Back up all data before making any changes.
Step 1
You might have to log out or reboot before a Flash update takes effect.
Step 2
In the Safari preference window, select
Privacy ▹ Remove All Website Data
Close the window. Then select
 ▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Delete All. Close the preference pane.
Step 3
If you're only having trouble with YouTube videos, log in to YouTube and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
Step 4
If you get a warning of a "blocked" or "outdated" plug-in, then from the menu bar select
 ▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Check Now. Quit and relaunch the browser.
If the warning persists, triple-click anywhere in the line below on this page to select it:
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources
Right-click or control-click the highlighted text and select
Services ▹ Open
from the contextual menu.* A folder should open. Inside it, there should be a file named "XProtect.meta.plist". If that file is missing and you know why it's missing, restore it from a backup or copy it from another Mac running the same version of OS X. Otherwise, reinstall OS X.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Open this folder as in Step 4:
/Library/Internet Plug-Ins
Delete the following item, or anything with a similar name, if present:
Flash Player (failing).plugin
You may be prompted for your login password.
Step 6
Re-download and reinstall Flash. Download it from the domain "get.adobe.com". Don't click a link from any other website, including this one, because you can't trust links. They may be an attempt to trick you into installing malware masquerading as Flash. Type the address into the browser window. Never download a Flash update from anywhere else.
Step 7
If you get a "missing plug-in" error, select
Safari ▹ Preferences... ▹ Security
from the Safari menu bar and check the box marked
Allow (or Enable) plug-ins
Then click the button marked
Manage Website Settings...
if present and make sure that the website is not blocked for Flash.
Step 8
Select
Safari ▹ Preferences... ▹ Extensions
from the Safari menu bar. If any extensions are installed, disable them.

IMac - Display doesn´t work after restart

My iMac 21 Display doesn´t work after restart. If I turn it off and 1 hour later I want use it again the iMac shows the white screen with the mac logo and then the display goes off. I connected an external display to check if the iMac was ON and with the external display I can login and do everything but the iMac Display doesn´t work .
If I turn it off and wait 3 or 4 hours and then turn it back on the display works OK.
This is very strange behavior I have spent hours and hours trying to fine the solution or a similar issue but nothing so I am looking help here at apple.com
BTW When I bougth the iMac 21 there were some spots over the display so the display was replaced by the provider. The warranty has expired by now.

To tell you the truth, I don't know if they have to repalce the LCD panel or what they do for a bad backlight. In this reality of block or assembly replacement it probably involves repalcing the panel and not the backlight component. Don't know what it would cost. You'd have to ask that of a service center.
