XI Server Availability

Hi,
I need some help regarding the information shown in available.log
It indicates that our server is unavailable since the day it was started
[Unavailable 07.06.2007 20:48:54 - 19.09.2007 09:54:08]
But, the XI server works fine.
Currently, the server usage is not that intense. Will there be any issue because of what is indicated in the available.log? Will the behavior be inconsistent and unpredictable?
Thanks!

Hi,
'available.log' is written by the SAP service sapstartsrv.exe. The
service checks the status of the actual process list
(like you can see in in the MMC SnapIn under the "Process List" node).
If all processes are "green" the instance is considered to be available
otherwise not. Since the status information of the Dispatcher is
calculated from multiple parameters (process running + connected to
message server + shared memory available + good dialog queue time)
the information in available.log is very reliable.
The information is checked and updated every 60 sec and at instance
startup and shutdown. The default threshold for a "good" dialog time
is 5.0 sec. You can adjust this threshold with the profile parameter
max_dia_queue_time in the default or start profile (service must be
restarted after changing it).
If the service notices that the last update to available.log is older
than 60 secs (e.g. due to computer shutdown), it will always start
a new line in available.log
No SAP application reads available.log it is just a simple logfile
to protocol system availability.
Award points if helpful.
Thanks,
Tanuj

Failure of server APACHE bridge::No backend server available for connection

All,
I have an env: Browser -> OHS -> WLS(Apex Listener) -> Oracle DB.
If any SQL run for more than 5 mins, i get the below error.
Failure of server APACHE bridge:

Regardless of the version, this is not exactly a "Forms" failure. This is an issue between OHS and WLS. Basically it means that OHS (via mod_wl_ohs) was unable to communicate with WLS_FORMS (or whichever managed server you are trying to access). Most often this means the managed server is not running or not responding. If you believe it is running and is responsive (test by hitting it directly) then the problem is probably related to your installation. Generally, if you have not properly configured your networking before you installed WLS and FMw, then this can occur. For example, on Windows machine which do not have static IP addresses, the Installation Guide instructs you to install the Windows loopback adapter and configure it. If you did not do this, OHS likely will not be able to contact WLS_FORMS.
You can test what I have described above by attempting to access WLS_FORMS directly. For example:
http://yourHost:9001/forms/frmservlet
If that works, the issue is probably related to a net config issue.
If you have access to MyOracle Support, refer to these notes:

There is no server available at the address you entered, codes: 25294, 9848

About a month ago I rebooted the server and after that Server Admin hasn't worked. It says always: "There is no Server available at the address you entered".
In /var/log/system.log:
Jul 22 11:58:51 mail servermgrd[14205]: SecIdentitySearchCopyNext returned -25294.
Jul 22 11:58:51 mail servermgrd[14205]: Got error -9848 for SSLHandshake
Jul 22 11:58:51 mail servermgrd[14205]: Exception in threadListen: Socket: Connect failed
From http://developer.apple.com/documentation/Security/Reference/certifkeytrustservic es/Reference/reference.html:
errSecNoSuchKeychain –25294 The keychain does not exist.
From http://developer.apple.com/documentation/security/Reference/secureTransportRef/R eference/reference.html:
errSSLBadConfiguration –9848 A configuration error occurred.
I have also bootable backup on another disk in which Server Admin is working. I have compared files from /etc, /Library/Preference and /var/servermgrd without finding really relevant differences. Are there other places I should seek?
On some point I have changed host name. Could that cause certificate error in this case? I have checked with "sudo changeip -checkhostname" that names matches.
I have tried making servermgrd to use regular connection instead of SSL by editing /Library/Preferences/com.apple.servermgrd.plist. After changing settings, I have killed or unloaded/loaded servermgrd and tested with lsof that proper port is working. But I guess Server Admin doesn't even try to connect to port 687. Is it possible to force Server Admin to connect port 687. E.g. writing "localhost:687" as address didn't worked.
I have tried creating servermgrd.conf, ssl.crt/ and ssl.key/ to /etc/servermgrd/ even thought they weren't there originally.
I have tried connecting with many different IPs and DNS names and done as instructed here http://support.apple.com/kb/TS2757. According lsof, ports 678 and 660 are not in use normally.
I have tried moving/trashing /var/servermgrd/ and ~/Library/Preferences/com.apple.ServerAdmin.plist.
I have tried stopping ipfilter.
Is it possible find out that which certificate servermgrd is trying to use?
What else I could try? The server is currently running email and web services among other things with many users, so therefore I can't try too rough methods.

Little progress maybe...
I tested Server Admin of the working backup while using "sudo fs_usage -f filesys <PID>".
When I did same with the actual nonworking server I noticed this difference:
18:53:09 statfs private/var/root/Library/Keychains 0.000010 servermgrd
18:53:09 open private/var/root/Library/Keychains>>>>>>>>>> 0.000008 servermgrd
Path /var/root/Library/Keychains does not exists and backup system doesn't seems to try to use it. I suspect that "errSecNoSuchKeychain –25294 The keychain does not exist" occurs because of this.
Any hints to fix this?

Leopard Server Admin Fails "there is no server available"

My Leopard Server has been running fine for months, uprgraded to 10.5.6 without difficulty a few weeks ago. Today, the Server Admin application is throwing up an error "there is no server available at the address you entered", with a box to delete it or save it.
Huh?
The server seems to be still running fine - mail continues to be delivered.
I note that this error has been reported before here and elsewhere, but there doesn't seem to be any comprehensive solution.
I would appreciate any help.

Hi
For the lack of any further information it's difficult to say? It could be anything or nothing at all? Have you tried a restart? Sometimes you'll see this error message if there's a problem with your keychains? You're more likely to see it if there is a problem with your DNS Service. Although not definitive does Workgroup Manager have a problem? Can you connect to the Server using Server Admin remotely?
You should be able to remove the server from the list and re-add it. You can use its .local name, its loopback address, its IP address or its FQDN. Whichever one its having a problem with use one of the other methods instead. Any or all of them should work.
To remove keychains you could use Keychain Access. Keychain Access > Edit > Keychain List. Select the ones you want and click the 'minus' symbol. I tend to not bother and remove them from /User/Home/Library/Keychains as well as /Library/Keychains followed by a restart. You can also 'reset' how Server Admin presents its interface on launch by removing its .plist from /Users/Home/Library/Preferences. Quit out if it first. Take the com.apple.ServerAdmin.plist to the trash, empty it and re-launch Server Admin. You might have to restart the server. There's a similar .plist for Workgroup Manager.
If you can't connect at all then you are probably looking at a problem with DNS Services. Can the server resolve itself to itself? Issuing host or nslookup for its fully qualified domain name followed by its IP Address should present a clearer picture. You could also issue:
sudo changeip -checkhostname
As this checks the validity of the Server's DNS. If it returns "DNS hostname is unavailable, please run the repair tool" then consult changeip's manual page. If it returns "the names match, there is nothing to change" then start looking at the physical structure of the network itself. An intermittent fault with the patch cable perhaps or Switch port?

SCOM 2012 R2 Management Servers and SQL Server Availability Groups

My team is in the middle of rolling out a brand new install of System Center Operations Manager 2012 R2.
I have set up a SQL Server Availability group that is spread across multiple subnets and installed the initial management server per
here.
As I have gone through attaching new management servers, I have noticed disturbing behavior. When the AG fails over to another node, the management servers will lose connectivity unless I either recycle the service or it fails back to the original
node. This is not a security issue as I have set up permissions. It says it cannot connect to the database anymore at all.
Has anyone else seen this behavior? Is there a setting I am missing somewhere?
Thanks for your help.

Offline installer for CC Desktop / Server availability issues.

This is a follow up to the issue described here: http://forums.adobe.com/message/5620240#5620240
As we have to install CC Desktop on each of the systems deploying CS6 packages, I'm looking for an offline installer for it. Is such a thing available?
The reasons I ask are that A) There's no guarantee that the machine will have internet access during the installation. and B) Half the time I run it on a desktop, I get an error message telling me "The remote server is not responding in a proper manner"; my response to which was similarly improper...
My "Deployment" such as it is now relies on users copying the file form a network share on to their desktops, running it individually and hoping that the server is online. Not fun when you've got 50 artists across 5 studios wanting to get these packages installe; and that's only so I can proceed to the wheel-of-fortune that is the AAMEE-produced MSI package.
Are these server availability issues commonplace? Is this just one of those things that afflicts all software launches that rely too heavily on online components?

Hi Terry,
If it's helpful, you can find and use all the original offline installers for all Creative Cloud and CS6 tools (including the CC Desktop App) here:
Adobe CC Direct Download Links
and/or
Adobe CS6 Direct Download Links
If you have those files in hand then you can install the free trials anywhere while being offline. In most cases the Internet is used to activate the software longer-term, although Adobe still provides procedures for offline activation:
Activate your software offline
If the computer on which your software is installed cannot connect to the Internet or to Adobe’s activation servers, you can activate your software offline.

Which are the third paty Converter Server available in Market

Hi,
I would like to convert my all drawing(dwg) & office(doc,xls,ppt) files in to PDF.
I can achive this functionality by sap converter server or I required third party converter server.
If third party then which are the third party conversion server available in market.
Regards,
Sunny
Edited by: Sunny on Sep 19, 2008 12:36 AM

Hi Sunny,
I can strongly recommend CIDEON's Conversion Engine.
It converts all your required data formats into PDF. It supports all major CAD-Systems (AutoCAD, Inventor, SolidWorks, Solid Edge, Microstation, Pro/E,...) and MS Office Applications.
It has extended monitoring capabilities and it is very stable and reliable due to not using the spool system.
Regarding the converter to PDF you have different options.
Create PDF with:
- Adobe Professional (Distiller)
- Ghost Script
- CIDEON PDF Writer
Find more information here:

No logon server available for Win 7 Pro to join new 2012 Standard domain

I can't get a Win 7 Pro client to join a new 2012 Standard network. I am trying to use a Win 7 Pro computer from an old 2011 SBS FE network. I am creating the new network from scratch and got as far as setting up the new server, establishing
Internet access, and confirming that the client can ping the new server, which accepted new user credentials for the new domain added to the old client. I rebooted. Now I get the message that no server is available to service the
logon request, for all domains and all user accounts on the old 2011 client, including the individual computer "domain." I can't access anything on the client. Server still accepts the user account and password.
Unsuccessful efforts: rebooting old client; searching archives for solutions; disabling DCHP on router; and jumping out window.
Suggestions?

Maybe DB2 UDB EEE (a Shared-Nothing architecture) might become

CSM Modules and Server availability project

I have 2 geographically separated sites, site A in the main office and site B is the Disaster recovery office. These 2 sites are connected by a high speed Layer 3 link (10Gb), The goal is to have duplicate servers available in site B in the event of partial server failure in site A or even complete failure of site A. Can I accomplished this with the CSM modules given that these servers will be in different networks and overall how would this configuration work, I really appreciate it.

Are you planning to put CSMs in both data centers or a single data center?
If CSM will be at one site (site A) only then
You need to use source NAT on CSM (Assumption: its in Site A) to make sure that the return traffic from servers in "site B"
can go back to the client through CSM at "Site A"
If both Data centers will have their own CSM modules then the best approach is to use GSS or any any Geo redundant setup that can check the load/health/availability/proximity of the VIPs (virtual ips configured on each CSM) in each data center and direct the clients intelligently to the appropriate data center.
