Hi,
I've got the exact same problem when launching to JDeveloper.
And I've searched on internet for days.
I did try to modify the number of
MaxPermSize in jdev.conf
and
Xmx and Xms in ide.conf
I've tried several combinations, and sometimes it works.
The disappoint fact is that even with the same combination of the settings, sometimes it works and sometimes it doesn't.
Sometimes it just work. Sometimes it doesn't...and after rebooting it works again......Sometimes even rebooting doesn't help.......Sometimes when change MaxPermSize to a smaller number it works...and next time it may not work again....Sometimes you change the MaxPermSize to some other number, save, and then change it back,,,,and it works again...but next time you try to use it, it may not work..........
I don't know what leads to these problems.....anyone could help? Thanks in advance....

JDev 12c: Unable to create an instance of the Java Virtual Machine

Hi!
I have installed JDev 12c on windows7 64 bit and try to start it the first time and get this error.
The path inside the message point to <myHome>\oracle_common\jdk\jre\bin\client\jvm.dll.
There is installed a jre, whichs version is:
<myHome>\oracle_common\jdk\jre\bin>java -version
java version "1.7.0_15"
Java(TM) SE Runtime Environment (build 1.7.0_15-b33)
Java HotSpot(TM) Client VM (build 23.7-b01, mixed mode)
In the calling batch script I see following output:
Error occured during initialization of VM
Could not reserve enougs space for object heap
Anybody has the same problem?
Kind regards
Torsten

Thanks Frank - i missed that a 64bit installer exist as the first installer does shows only windows installer and not 32bit installer!
One last question:
After the start remains the calling command window additional to the JDeveloper window, is this the wanted behavior? As this use the same icon in the task bar this leads to wrong switch to this windows instead of the JDeveloper window.
The calling command window shows only this information:
Jul 15, 2013 10:48:20 AM oracle.ide.osgi.boot.LauncherUtil throttleLocale
INFO: Locale de_DE is not supported by this product. Forcing locale to en_US.
But when I close it the JDeveloper window is closed too.

How do I create a Public Group on the Calendar Server?

How do I create a Public Group on the Calendar Server?

Anyone can create Private Groups or Member Only Groups. You must be given
administrative rights to create Public Groups on the Calendar Server. The
Calendar Server Admin (SYSOP) can give anyone rights to create Public Groups by
using the uniadmrights tool.

Go to /users/unison/bin/
and run the uniadmrights
tool. Some sample syntax:

To list all users with administrative rights:
% uniadmrights -ls -host yourhostname

To give John Smith, a user on node 10000, rights to administer Public Groups:
% uniadmrights -e "S=Smith/G=John" -add -pgrp -n 10000

In Calendar Server 4.0, you also have the option of using the Admin Server GUI
to assign Administrative
rights (instead of using the command-line method) by going to User Management,
Administration Rights.

With the proper administrative rights, log into the Calendar Client. Go to Options,
Manage Groups to create a new group. Choose PUBLIC from the dropdown window,
add your users and/or resources and click OK to create the Public Group which
can be seen by all users on the local Calendar Server.

The following is info that I found in another post that I have been trying to follow.

Re: Configure DNS - OS X Server Next Steps
Feb 13, 2011 6:36 AM (in response to Jimbooooooo)
You're setting up internal DNS services, you referenced your ISP DNS servers and you should not have, and now those servers have no translations for your hosts. This is a common misconfiguration.
See [configuring DNS on Mac OS X Server|http://labs.hoffmanlabs.com/node/1436] for how to set up your internal DNS server.
And if there are any references to your ISP DNS servers here (within your client settings, within your server settings, your Airport settings, etc), then you're usually going to have DNS and connectivity problems. You're running a server now, so you'll be running your own services, and (particularly because of NAT here) referencing only your own DNS server(s).
You may be setting up external DNS (if and when you need that), but that should happen after you set up your internal DNS. The above article has a link to setting up external DNS, when you get around to that, if/when you need in-bound connections into your LAN.

Two instances on the same server

I've already created one instance on 11g R2 database, but I was told to create another instance on the same server. Can I use the same listener for both instance? Will it cause any problem?
Thanks!

tanww888 wrote:
Thanks for all your responses. I have not dealt with two instances on the same server before. I'll take your advice to start with the same listener for both instances and see if it is causing any issue. My database server is a Oracle Sparc 5120 with plenty of memory and disk space. The second instance that I'm going to create will be much smaller than the first one.
Single or multiple listeners aren't really a factor for performance. Notice that even in Dan's remarks, none of his reasons for multiple listeners had anything to do with performance.
Question, is it easy to create/configure the second listener to point to the second instance? Just in case there is an issue using the same instance.
The listener doesn't "point to" the database - not in the sense you seem to think. It simply watches the ports it is configured to use (1521 by default) for connection requests from clients. When it gets a request it evaluates whether or not it knows about the service (instance) requested, and if it does it spawns a separate server processes to communicate between the client and the db instance, then is out of the way. The listener creates the connection but does not sustain it. You can stop a listener and all existing connection will continue because the listener has no part in maintaining them.
Multiple listeners would be configured by adding LISTENER sections to the listener.ora file. You might find it instructive to realize that if there is no listener.ora, a 'lsnrctl start' will cause a default named listener to start on the default port of 1521. By default, any db instances on that server will register themselves with the default listener on the default port. After this self-registration, the listener will know about the instance if/when it receives any connection requests for it. Let's switch from the telephone analogy to that of a desk clerk at a hotel. He comes to work and is handed a piece of paper that says "We have Tom, Dick, and Harry registered as guests" This would be analogous to the listener learning of instances via the SID_LIST section of the listener.ora file. Then Fred walks up and says "I'm Fred and I'm in room 238", so the clerk makes a note of that. This would be analogous to the instance registering itself to the listener. Either way, then someone walks up and says "Where would I find Tom (or Fred)". The clerks checks his lists and directs the person to the correct room. He doesn't escort the person around to Tom and act as a go-between for their conversation. And hotel management doesn't want to have to pay a separate clerk for each guest.
You might want to read my articles about TNS in general at edstevensdba.wordpress.com. I think they will help you get a clearer understanding.

You should not install it again..
Boot the computer into safe mode and try the uninstall again.
No luck you will have to manually uninstall which is a pain. Delete the files and open regedit and delete the registry entries.. better still use the system restore to go back to a previous system where you had no 4.2 installed..
Or just ignore it and install the latest 5.6.1 and if it gives trouble well do a clean install of windows.

Error 1647: Unable to create installdrivers instance

Error 1647! Unable to create installdrivers instance
Return code: 2147312566....I'm trying to find a solution on this error message. Haven't had much luck! This error message appears when I try to install updates to iPod and iTunes.
Most of what I've read isn't clear. Most importantly, I'm afraid to add anything to the system language. Any easy solutions? Can I continue to run my current (old) versions of the iPod updater and iTunes?

Thanks!

"OIP-04796 Unable to create object instance"

I am using OO4O, version 3 for Oracle 8.1.7 on Windows with Visual Basic version 6.
I am getting the intermittent errors "OIP-04796 Unable to create object instance" and also "Method createDynaset of _IOraDatabase failed" - I think both are related to one another and from the documentation for OO4O, "OIP-04796" relates to the client side object cache of the OraDatabase class. Reasoning that the client side object cache was too small I attempted to increase the relevant properties of the OraDatabase object using the following: -
MyOraDatabaseObj.CacheOptimalSize = 400
However, at run-time, this property of the OraDatabase object does not get set accordingly in the VB IDE and after several attempts I can't seem to set it. I have also tried setting the CacheMaximumSize property but to no avail.
Can anybody indicate to me where I am going wrong and either with the setting of the above properties or with the error message in general if I am not on the right track with the cache properties. I don't suspect that it is my code because the problem "seems" to be intermittent.
Any and all help would be greatly appreciated. If more info is required then just ask as this is pressing problem.
TYIA
Mark Grimshaw

I am pretty sure the patches are available here. If you didn't explicitly install one then you have whatever the base release was.
If they are not available here (I almost never look here first for a patch) they are certainly available in the MetaLink file library for OO4O.

DRM-61026: Unable to create user session for the following reason: Login failed. Invalid user name or password.

All Im very new to Oracle DRM and Im trying to get the app setup on Windows server running SQL Server 2008. When I try to login to the Web Client I keep getting this error.
DRM-61026: Unable to create user session for the following reason: Login failed. Invalid user name or password.
Can you please help

This might be due to The 'Oracle Instance' path may not have been set to a path relative to the 'CSS Bridge Host' (i.e. the Foundation Services machine) on the Configuration > Host Machines > CSS > General tab of the DRM Configuration Utility.
if this is the case then
1. Open the DRM Configuration Console.
2. Go to the Configuration > Host Machines > CSS > General tab of the DRM Configuration Utility.
3. Ensure that the path in 'Oracle Instance' has been set relative to the 'CSS Bridge Host' (i.e. the Foundation Services machine defined in 'CSS Bridge Host').
4. If corrections are made to 'Oracle Instance' then restart the DRM services to pick up the change.
Thanks,

Unable to create an instance JVM - Antivirus

I have problem with antivirus scanning of JVM files. Message 'Unable to create an instance ...' appears only when AV is running. PC admins do not permit disabling of scan jre files.
By AV log file, there is big time delay on full jre scanning. Exists any settings to increase time to wait for JVM start?
Thanks a lot.

I had a similar issue, so I killed some parts of AV in the registry. There isn't really anything that we (the forum users) can do except to tell you to raise this again at your company. Many policies can be altered if the policy breaks software, and this should be the case. However, you may need to be quite persistent to accomplish it.
