Shared server problem.

Has anyone every had this issue occur?
I had a system slow down on one of our database servers, running Linux AS3 Oracle 10g (10.1.0.2.0). During the slow down (CPU spikes), sqlplus querries were running very slow on our client/server applications connected. The alert log shows this:
found dead shared server 'S002', pid = (13, 1)
I have never seen this before, what do you recommend. We normally run shared servers set at 50, I found that this was a bit high considering we normally see s001-s005 running. Shortly after the dead server error I dropped the shared servers from 50 to 20, that seemed to curb the high CPU spikes. We currently run on dispatcher as well, should I have more dispatchers running to handle the 20 shared servers? I have done the math, and it looks like we need only 2 dispatchers, but I was curious to know if increasing dispatchers and lowering shared servers is a true benefit to performance.
Thanks again for any advice, I do not know what impact a dead shared server means, does Oracle simply move to s003 and disregard s002 if it is dead?

We changed our database from dedicated server mode to shared server (since users were not able to connect to the database...listener log showed tns-12518 and related errors....previously it used to show ora-04030 in alert log).
You have switched to shared server just because users were unable to connect? I think you need to fix the problem before thinking of switching to shared server.

MTS (shared server) problem

Hi,
when i use MTS (shared server) architecture, after a while,
i see 1500 sessions in v$session, but, about 4000 oracle processes in the operating system which hits the os user max process limit and get the following error.
how can that be? 1500 sessions in v$session, and, 4000 oracle processes in OS.
i can not reproduce the same case since this is production.
in test, i tried to reproduce the case but even though, i create mts sessions once in a second, after 1 hour, no problem.
shared_server=10
max_shared_server=50
max_dispatchers=2 (each with 250 connections)
thanks,
ORA-27300: OS system dependent operation:fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
ORA-27302: failure occurred at: skgpspawn3

Afew things to check, firstly are the connections actually using shared server? check ther server column in v$session session may show as dedicated in which case th eocnnection is requesting a dedicated server and is ignoring the shared server configuration.
next check v$process have you got 4000 processes listed there? if so you can connect them back to the sessions e.g.
select vs.sid,vs.serial#,vs.username,vp.SPID,vp.PROGRAM
from v$session vs,
v$process vp
where vs.PADDR=vp.ADDR

Oracle 10g Shared Server Problem Please Help

Hi
I am studying for Oracle 10g OCP ; I was trying to start the shared server feature of oracle10g ver 10.2.0.
The database name is :CERTIFICATION10g
The listener name is: LISTENER_CERTIFICATION10g Port:1521
I could register the dispatchers successully with the listener above. However when I open a new connection ; instead of going through the dispatcher it uses the dedicated connection. I tried opening many sessions but the established filed for both dispatchers remained 0
I post a dump of the lsnrctl services command below:
LSNRCTL> service listener_certification10g

Why are the connections not being routed through the dispatchers? Any additional setting needs to made?

Maybe because you have in your listener.ora used by your client only this entry:
XXX =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = YYYY)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED) -> should be SHARED
(SERVICE_NAME = XXX)
(INSTANCE_NAME = XXXX)
(HS = OK)
)

Problem with shared server mode

Hi,
I want to run my database in shared server mode.I have configured the fallowing parameters in init.ora
SHARED_SERVERS=2
MAX_SHARED_SERVERS=10
DISPATCHERS="(PROTOCOL=TCP)(DISPATCHERS=2)"
Then I opened the database.
In another sql*plus session and logged in as scott.There i ran a script to insert 50,000 record s into a table.When the script was running i opened another session as SYSDBA and queried v$shared_server view.
It showes.
NAME PADDR STATUS MESSAGES BYTES BREAKS CIRCUIT IDLE BUSY REQUESTS

S001 54C968A8 WAIT(COMMON) 0 0 0 00 56758 0 0
Why it is ahowing status as WAIT and requests 0.
What is wrong with my init.ora setting.Please help me.

Hi,
Shared servers (the MTS) does not use PGA RAM, it gets RAM from the large_pool_size region.
BTW, I don't recomend using shared servers unless you have an acute RAM problem:

Problems establishing a Shared Server connection

I am trying to establish a connection to a shared server on a test database. The database is 10.2.0.4 and runs on Solaris 10. Here are some setting for my init file, and I think the last two do not need to be set.
# Shared Server
dispatchers="(PROTOCOL=TCP) (SERVICE=DBA10XDB)"
shared_servers=5
shared_server_sessions=20
I connect from my client which uses a tnsnames.ora file and does NOT specify a dedicated server. Here is the result of LSNRCTL SERVICES:

The command completed successfully
V$SESSION shows the connections to be DEDICATED. Any suggestions as to what I may be doing incorrectly? Reading all I can find on this seems to indicate all I need to do is have DISPATCHERS and SHARED_SERVERS set and then connections will automatically be shared server connections.

Thanks. Your post helped me get things straightened out. After changing my tnsnames file I was getting an ORA-12520. Hmmm. I then noticed the (SERVICE=DBA10XDB) on my DISPATCHERS parameter, which was there by default when Oracle configured the init file initially. I removed that and it worked.
Then I was able to get connections to the shared server with and without the SERVER=SHARED setting. I knew I had read that Oracle will default to shared server if not specified, but your post indicated that a client connection can be forced to use the shared server, even when no dispatchers are registered. I think mine was not registered to my instance due to the (SERVICE=DBA10XDB) setting. If there are no registered dispatchers the connection request is rejected.

On 10.9 - I can no longer open, copy or preview files on a shared server

I am on a 2007 iMAC and I connect to a shared server in our office. I just upgraded to 10.9 and am experiencing a number of problems:
- When trying to open files through finder I get the notification "Application not found"
- When trying to copy to/from server I get error mssages 43 or 8058
- Can't drag files into applications shown in dock
- Vectorworks 2010 not working at all
If I open an application and use File/Open and select files from the server they open fine, but I need to be able to use finder & preview...
I think the above issues might have something to do with permissions?
Please help

I've had the same issues. For me, trashing the permissions didn't resolve anything. The only work-around I've found is force quitting/relaunching the Finder. I have to do it every day, sometimes twice, but at least I can drag, copy and double click on files to launch an app.
Hope that helps.

How to set up a basic file sharing server for my small architectural business?

I have no idea if I have posted in the correct area as this is my first forum post within the apple support community!
I have been using a 21.5" imac running 10.6.8 for the past 5 years to run my small home based architectural design business. I have been using the internal hard drive & backing up the necessary data to a simple usb external hard drive. I am now looking to firstly purchase a new imac 27" retina and purchase new autocad lt 2015 for mac software. I am looking to have another imac (my old mac) running in conjunction with the new mac. I want both macs to be able to access the same data and am slightly unsure what is the best way to achieve this.....As my old mac is currently only running snow leopard and an old version of autocad for mac 2011 it wont run on any more recent OS. Essentially i believe I have 2 main options with this.... (1) I Accept that I have to purchase 2 no. autocad lt 2015 licences @ a cost of £2300. Or option (2), I only run autocad on the new mac as this will be the primary station and the old mac used for primarily for admin & accounts. I have also recently discovered that it is possible to rent autocad licences for £300p/a which may also be another option (3)!
I previously had a problem where my hard drive failed on my mac & lost all data on the internal hard drive, luckily I had been backing up all data regularly to my external hard drive and now loss occurred! Obviously with any new system I want to ensure that my data is safe!
I currently utilise about 250GB of data for business operations but this will obviously grow with time.
In the future I would like to have the option of potentially being able to access the network data remotely via macbook pro whilst abroad although at this stage this really isnt my primary objective. Although I believe I could achieve this through apple remote desktop.
I suppose I should provide some information with regard to the required speed of the system...I regularly open 50-100 photos at the same time totalling around 250-500MB. I would like the system to be able to handle this fairly easily.
I have been trawling through forums and to be honest they are totally confusing me. I have also spent time on the phone to the apple business team and have also discussed my objectives with a member of the apple team in store.
There have been various options advised to me and I really do not know which is the most appropriate route forward.
1 - Using a mac mini as the file server and linking the 2 mac devices to this and backing up the mac mini to an external hard drive to ensure no loss of data.
2 - Using a time capsule as a file server and linking the 2 mac devices to this and backing up the TC to an external hard drive to ensure no loss of data.
3 - Using the new mac hard drive and linking the 2 macs via thunderbolt (old mac does not have thunderbolt and so I guess I would need another new mac?!) and then backing up the data to a time capsule.
4 - Using a RAID based server and linking the 2 no. macs.
Sorry to ramble but any advice really would be greatly received!

Hi sblemings,
Welcome to the community.
I think with your scenario you should ask yourself, how complicated do you want the setup to be and how much time would you have to be able to resolve an issue should one occur with this setup.
All the options that have been advised would work but they come with complexity and therefore time.
1 - Using a mac mini as the file server and linking the 2 mac devices to this and backing up the mac mini to an external hard drive to ensure no loss of data.
2 - Using a time capsule as a file server and linking the 2 mac devices to this and backing up the TC to an external hard drive to ensure no loss of data.
3 - Using the new mac hard drive and linking the 2 macs via thunderbolt (old mac does not have thunderbolt and so I guess I would need another new mac?!) and then backing up the data to a time capsule.
4 - Using a RAID based server and linking the 2 no. macs.
Sorry to ramble but any advice really would be greatly received!
option 1
Would be a way to achieve what you want, it would centralise your files and you would only need to backup your file server (as long as all the files you wanted backed up were on it). This could be achieved either using the client and sharing various folders or using Server which would give you more options than you would possibly need.
option 2
This is exactly like option 1 except that you wouldn't have to administer another mac however you may limit any future growth.
option 3
This option I probably wouldn't pick, you could achieve this with firewire and use a firewire to thunderbolt adapter (saves you having to buy a new iMac)
option 4
This option would, depending on your RAID level, give you disk redundancy but remember you would still need to back this up, as RAID is NOT a backup solution.
I would also ask is there a pressing need to keep the old iMac in service and complicating things by having a server / NAS? Could you not just transfer all your information over to this and continue with the one backup? I would say that doing it this was would be the simplest way of achieving what you want from what I can take from your question.
As for remotely accessing your data, if you have the right hardware the way to achieve this would be to use a VPN and connect back to your data. However a potentially easier way for you ,would be to use a service like logmein or teamviewer to connect back.
Hope this helps, and by all means any questions please ask.

APEX error: Found dead shared server

Hi,
I frequently encounter an error when working with APEX. If I submit any change to APEX, fi a change on some page item, APEX asks me to whether I'd like to save the wwv_flow_accept URL. I then get a file save dialog. This doesn't happen all the time, but something like 2 out of 10 times I submit something.
Looking at the database logs, I see an entry in alert.log with this information:

Hi,
I took a bit of time to dig deeper into this issue. I came to the conclusion that there is a bug in Oracle XE:
If you connect to Oracle XE database using the EPG path and if you create a report that gets its data over a database link, the shared server processes used to connect to the database break.
What I did to produce this error:
I installed Oracle XE Universal Edition on a Windows XP system
I then updated APEX to the latest version 3.2
At the database I simply created a database link pointing to the same schema the APEX-application is running at. I tested the database link.
I then produced a simple test application with just one Report (I also tried a PPR-report with the same result) that displays orders with a query in line with this:
<pre>
select o.order_id, i.order_item_id, i.quantity, p.product_name, i.unit_price, i.unit_price * i.quantity amount
from demo_orders@ckh o, demo_order_items@ckh i, demo_product_info@ckh p
where o.order_id = i.order_id
and i.product_id = p.product_id
order by o.order_id, i.order_item_id
</pre>
When I ran this application, I was sometimes able to see the report without an error, sometimes a shared server process broke. You can watch the processes breaking by opening the admin/bdump directory and see how the database writes trace files for the shared server processes.
Interesting to see is that the error happens not only when you try to see the report. If you hit the edit page link while running the page or if you submit the page definition with the link query in it, the same is likely to happen. You can see this error happening when APEX offers you to download the call to wwv_flow or the f-procedure. The contents of this download then is:
<pre>IBMPC/WIN_NT-8.1.0</pre>
with some binary information in front of the message.
Another bug I'd like to add came up when I was lucky to see the report with the PPR-template. I tried pagination but this wouldn't work. Looking into this, I found the following link:
<pre>
javascript:html_PPR_Report_Page(this,'R2060428410112776','javascript:$a_report('2060428410112776','16','15','15');')
</pre>
To my understanding this can't work at all if you look a the apostrophes. So how to proceed with this???
This to me is a severe problem, as I wanted to utilize APEX as a frontend for a production database to report the contents. I was informed by Varad that a way around this is to use an Apache access to Oracle XE but as far as I'm informed, this forces me into a licenced version in order to be able to run mod_plsql.
I read about the mod_owa-approach, but the programmers state that this is not compatible with APEX. So my question is: Do you have any suggestion on how to proceed with this?
Thanks,
Jürgen

Oracle 10gr2 rac, ora-12545 error when configured in shared server mode

Hi i have fresh installation on two node rac on linux, with oracle 10gr2. It is running successfully, when i configure it in shared server mode and try to connect from client it gives error ora_12545:
I have referred the oracle metalink notes and configured the local_listener as well as the remote_listener,
still it is giving the error. I am able to tnsping all the entries on tnsnames.ora,
i m also able to ping the hostnames,
It connects most of the times succeessfully but some times it gives the error.
how to solve this problem,
please help me

Basically this error means you misspelled the hostname or typed a wrong IP Address.
Oracle Error :: TNS-12545+
Connect failed because target host or object does not exist
Cause
The address specified is not valid, or the program being connected to does not exist.
Action
Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
I suggest you to check the dispatcher instance parameter.

Any idea for high display resolution in application sharing server ?

Hi.
I installed EP6 SP 13 with KMC and configure collaboration feature.
I tested application sharing and It works.
Then, I found problem.
Problem is that application sharing server doesn't support 1400x1050 display resolution. (only works till 1280x1024)
Is there any idea for solving this issue ?
Regards, Arnold.

Hi Arnold,
I'm afraid this screen resolution is not yet supported. The official supported screen resolution is 1024x768 ! but as you stated it can work wit 1280x1024. You could open an OSS ticket and ask the KM Development for plans on supporting higher resolutions in application sharing and let us also know.
Hope this helps,
Robert

Oracle shared server default connection

We are currently trying to use shared server on an Oracle 11.1.0.7 standard edition database.
We don't have any problem regarding parameters or performance yet. We can connect either with dedicated or shared connection.
Our problem or issue is with tnsnames.ora.
trdb =
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = X.X.X.X)(PORT = 1521))
(CONNECT_DATA =
(SID = orcl)
We do not specify if this connection is shared neither dedicated. Connection defaults to dedicated and we would like to force that users connect to a shared server connection.
It would be really usefull to avoid having to go client by client on remote sites. We do no have any centralized management tool to change the file (not on remote sites).
We could, of course make the application to distribute a new file, but since every client is unique, it could be risky.

Try to use SERVICE_NAME instead of SID in tnsnames.ora and make sure this service is mapped to a dispatcher in database init. file.
Example with 11.2.0.1:
1. DISPATCHERS parameter
SQL> show parameter dispatchers
NAME TYPE VALUE
dispatchers string (PROTOCOL=TCP) (SERVICE=DB112XDB)
max_dispatchers integer2. TNSNAMES.ORA:
$cat tnsnames.ora
DB112 =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = lx01.localdomain)(PORT = 1521))
(CONNECT_DATA =
 (SERVICE_NAME = DB112XDB)
)3. Test with SQL*Plus:

SAP db upgrade to Oracle 10G 64 bit - Dedicated or Shared Server ?

We current run 32bit servers ( approx 150 users ) and plan to migrate to ECC 6.0 on 64bit bit server. Question about upgrade from Oracle 9.2.0.8 32bit to 10.2.0.4 64 bit . Database upgrade Oracle 64 bit should be Dedicated or Shared Server? 
My understanding ( limited), is Oracle 64bit dedicated server connection has the dedicated resource so whether or not a user is doing work the connection remains allocated to that user. So for example, in our case a small Windows "shop" will needs around 2MB of kernel space. So 150 threads, for 150 dedicated server connections, approx 150 x 2MB RAM. Correct ? 
Whereas Shared server the user connection is shared, that is user is connecting by dispatchers and when a user is idle his resource can be used by other users, thus lessen the load on system. So in this case maybe 5 dispatcher processes and 30 shared server processes to service the 150 sessions of the 150 users which seems very effective to me . My main concern however is with some of the Finance people who get problems with huge COPA and SIS reports now which is why we are moving to 64bit OS/DB/SAP 
Question is which does SAP ECC 6.0 support ( or recommend ) Oracle 64 bit Dedicated or Shared Server db migration ?

> Question is which does SAP ECC 6.0 support ( or recommend ) Oracle 64 bit Dedicated or Shared Server db migration ?
Never heard that anyone uses shared Server Setup with SAP.
With SAP, it is NOT the user having a DB connection.
It is the workprocess, and it is keeping it even if all users are idle.
You allways have dedicated Oracle processes for SAP Workprocesses.
The rather old note 70197 states, that Oracle MTS (multi threaded server)
allowed, but you are on your own to configure it and there are some pitfalls.

Oracle 9i Shared Server Configuration

My working platform is as:
O.S. : Windows 2000 Server
Database: Oracle 9i Release 2
Database Configuaration is as:
Database: Manually created (not the default one) and SID = test
Listener :
Name: listener1
Port No. : 1523 (Not the default 1521)
Associated with "test" database.
Dispatchers: (PROTOCOL = TCP) (DISPATCHERS = 3)
Shared Server: Set to 2
At Client side (connected through LAN) : I am configured a "Service Name" using Oracle NetManager and Set the following parameter : Connection type = "Shared Server", SID = test, Listener Port = 1523, Host Name = IP Addrs of Server Machine
In this scenario, whenever I want to test the connection from client side (from Oracle NetManager), it shows the following error message.
Listener is not configured to handle this type of connection
Please help me to solve that problem.

"Listener is not configured to handle this type of connection"
When I try to connect through Listener which is running at non-default port ( i.e. apart from 1521) the above message is shown.
As soon as, I checked the service status of the running listener and I observed that listener is handling one handler which is for "Dedicated" only. There is no other handler initiated for that listener to handle "Dispatchers"

Shared server wait(reset)

Hi,
I have a problem with shared servers.
On a RAC database, 2 instances, I use shared servers.. 30 for each instance.
recently the shared servers become in a wait(reset) status . a that moment, the connexion becomes very long and queries take a long time to execute.
I added 30 shared servers on each instance with no amelioration. everything works fine when the shared servers status comes back to wait(common).
any idea why the shared servers become in the wait(reset) status ?
any ways to prevent (solve) this?
is it a consequence of something else ?
... dedicated conn always works fine...

Hi,
What does the v$shared_server view tell you about these servers when they are in wait(reset) status?
Edit: This link http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10755/dynviews_2093.htm gives more information about the statuses in v$shared_server.
WAIT (RESET) means "Waiting for a circuit to reset after a break"

IMac cannot connect to a certain shared server

My iMac is currently connected to a network. When I open my finder, it show's all the computer/servers I can connect to under the tab 'Share'. I click all button (to see all the shared computers/servers).When I come to connect to the server I want, it says 'Connection failed'.
When I click on connect As it give me this error :
There was a problem connecting to the server “XXXXXX”.
The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again.
Another iMac can connect to the network/server, so I know it's not a server problem. I have been searching a while, and have tried a few suggestions that said to try change some of the options of the shared settings, but nothing has worked so far :/
I would be grateful for any help!

Luckily for you, I did figure it out
1. Finder -> Go -> Connect to Server (or cmd k)
2. put user and pass into the connection string, here an example: "smb://user:pass@servername" (without the quotes)
Essentially just connect to "smb://user:pass@servername" and login, with user name and password. Then you should be all set!
Hope that helps.

Shared server problem.
