FULL GC - Long time and frequently

Hi, sorry I'm new about JVM.
I have the following JVM:
java version "1.4.2_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_11-b06)
and often I have the following "heap" log:

Frequent Full GC has happened as far as your application is concerned. The time taken to complete a Full GC cycle is very, very expensive.
The end-user of the application would experience very slow response.
Due to the requests for new (may be large object) allocation that were in queue, the GC was trying to clear the objects from the PermSpace.
But there seems to be no enough space in PermSpace for the future allocation, so the OutOfMemory error.
What is your application all about?

I haven't used my desktop iMac in a long time and can't get pass the opening login...I thought I remembered my password, but, apparently not. How do I change it. I don't THINK I have a "master password" on the thing. I've never used one on any of

I haven't used my IMac in a long time and went to boot it up, and I find I don't remember the correct username and password (I use several computers..I try to keep the passwords similar, with a number for the chronological order in which I started using them) I've tried all the others I use for passwords. The 'hint" keeps coming up for the password I am pretty sure is the correct one, but, still cannot get in. I also don't remember whether I changed my surname on the computer...it was changed legally a little while ago, but some of my older devices still have my birth-name in there)
HELP
I don't think I ever set up a "master password" on the thing...I never use those. I am the only person with access to my personal devices.
thanks

The activation server for Audition 3 was shut down by Adobe several years ago.
You now need to download the non-activation version provided by Adobe here

Install then enter the new serial number provided by Adobe at that link. Your existing serial number will no longer work.

Creation of Transfer Order takes a long time and finally throws spool error

Hi,
I create Sales Order of type OR. I do delivery successfully. But when i proceed to create Transfer Order, it takes painfully long time and finally after painful 30 mins or so, it throws a error message, 'Error in spool call' with a blank page. I click on save icon and transfer order is created.
But the creation takes very long time. I checked SP01 and there are no requests.
Any suggestions will be rewarded.

I turned off my fire vault by accident and is there a way to stop it from decrypting cause that is going to take a long time and i want to keep my hard drive encrypted

I turned off my fire vault by accident and is there a way to stop it from decrypting cause that is going to take a long time and i want to keep my hard drive encrypted.
is there a way to stop it in the middle so it does not go through the whole process

It's called, "FileVault." If there is no option to stop the process, then the best bet would be to wait until decrypting is finished. Otherwise you run the risk of borking the whole thing. It's hard to imagine how you can accidentally turn off FileVault.

TS1425 ipod nano won't synch, i plugged it in to computer after not synching for a long time and it wouldn't install a new driver and now itunes doesn't even recognize it when i plug it in

ipod nano won't synch, i haven't purchased anything in a long time and haven't synched with the computer just charged on car charger. when i plugged the nano in it tried to install a driver and that failed and now the computer and itunes won't even recognize that the nano is plugged in.

REPOST (this solved my problem!!)

"The device manager just needed to be prompted to use the driver for an Apple Mobile Device instead. The Apple driver was already in my PC - I just had to prompt the device manager to use it instead of the camera driver it kept installing. Here's what I did:
I right-clicked the iPhone in Device Manager and chose Update Driver (for me, the iPhone was showing up in the Device Manager under Imaging Devices).
I selected "Install from a list or specific location (Advanced)" and clicked Next.
I chose "Don't search. I will choose the driver to install" and clicked Next.
In the next window there were 2 drivers to choose from: the "Digital Still Camera" driver that my PC kept thinking the iPhone was, and Apple Mobile Device USB Driver. I selected the Apple Mobile Device driver.
The driver installed, and at that point iTunes 9.2 could finally detect the iPhone. Yay!"

Hi, original poster here. I did not realize this would generate more discussion so I never checked back. I still had my warranty, so I took it to the store and got it repaired. The original problem I had was a screen with this icon flashing when I attempted to boot it up:
When I took it to the store, they told me that my computer was unable to communicate with the hard drive. I had this same problem three times in two months where this screen reappeared. Each time I went back to the store and they said the cause was different, but they were all hardware issues that physically made it impossible to communicate with the hard drive. After the third time, they simply replaced my laptop and I haven't had the same problem.
So in short: The reason you can't reinstall or move anything when you encounter this screen appears to be because nothing can communicate with the hard drive in the first place. You can't reach the disk or anything on it. So I don't believe it's possible to do anything besides take it to a physical store and have it fixed.

Query Saving takes long time and giving error

Hi Gurus,
I am creating one query that have lot of calculations (CKF & RKF).
When I am trying to save this query it is taking long time and it is giving error like RFC_ERROR_SYSTEM_FAILURE, Query Designer must be restarted, further work not possible.
Please give me the solution for this.
Thanks,

Hi Chowdary,
Check the following note: 316470.
https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=316470
The note details are:
Symptom
There are no authorizations to change roles. Consequently, the system displays no roles when you save workbooks in the BEx Analyzer. In the BEx browser, you cannot move or change workbooks, documents, folders and so on.
Other terms
BW 2.0B, 2.0A, 20A, 20B, frontend, error 172, Business Explorer,
RFC_ERROR_SYSTEM_FAILURE, NOT_AUTHORIZED, S_USER_TCD, RAISE_EXCEPTION,
LPRGN_STRUCTUREU04, SAPLPRGN_STRUCTURE, PRGN_STRU_SAVE_NODES
Reason and Prerequisites
The authorizations below are not assigned to the user.
Solution
Assign authorization for roles
To assign authorizations for a role, execute the following steps:
1. Start Transaction Role maintenance (PFCG)
2. Select a role
3. Choose the "Change" switch
4. Choose tab title "Authorizations"
5. Choose the "Change authorization data" switch
6. Choose "+ Manually" switch
7. Enter "S_USER_AGR" as "Authorization object"
8. Expand "Basis: Administration"/"Authorization: Role check""
9. From "Activity" select "Create or generate" and others like "Display" or "Change"
10. Under "Role Name", enter all roles that are supposed to be shown or changed. Enter "*" for all roles.
11. You can re-enter authorization object "S_USER_AGR" for other activities.
Assign authorization for transactions
If a user is granted the authorization for changing a role, he/she should also be granted the authorization for all transactions contained in the role. Add these transaction codes to authorization object S_USER_TCD.
1. Start the role maintenance transaction (PFCG).
2. Select a role.
3. Click on "Change".
4. Choose the "Authorizations" tab.
5. Click on "Change authorization data".
6. Click on "+ manually".
7. Specify "S_USER_TCD" as "Authorization object".
8. Expand "Basis - Administration"/"Authorizations: Transactions in Roles".
9. Under "Transaction", choose at least "RRMX" (for BW reports), "SAP_BW_TEMPLATE" (for BW Web Templates), "SAP_BW_QUERY" (for BW Queries and/or "SAP_BW_CRYSTAL" (for Crystal reports) or "*". Values with "SAP_BW_..." are not transactions, they are special node types (see transaction code NODE_TYPE_DEFINITION).
Using the SAP System Trace (Transaction ST01), you can identify the transaction that causes NOT_AUTHORIZED.
Prevent user assignment
Having the authorization for changing roles, the user is not only able to change the menu but also to assign users. If you want to prevent the latter, the user must loose the authorization for Transactions User Maintenance (SU01) and Role maintenance (PFCG).
Z1>Note
Refer to Note 197601, which provides information on the different display of BEx Browser, BEx Analyzer and Easy Access menu.
Please refer to Note 373979 about authorizations to save workbooks.
Check in the transaction ST22 for more details on the Query designer failure or query log file.
With Regards,
Ravi Kanth.

Hi Chetans,
I have had the same problem, and I had to create a OSS message to SAP in order to solve this issue, until now I don't have an answer. They made me to change a lot of configuration in Java and BW without luck. To tell you more, when we try to export to excel the java instance restarts aumotatically.
But we have this problem, when we try to export a huge quantity of data, so I found a note which says the limitation of exporting to excel. Take a special attention to the Performance section.
Note 1178857
[https://service.sap.com/sap/support/notes/1178857|https://service.sap.com/sap/support/notes/1178857]
I recomend you that you create a message to SAP. If you find a solution, please let me know.

My phone went into recovery mode and had to be factory restored, I hadnt backed it up to either the cloud or a computer in a long time and therefore I have lost all of my messages. Is there anyway to get the messages without a recent backup?

You are correct. Syncing should transfer any purchased media, including videos, from your device to your iTunes library provided your computer is authorized for the Apple ID used to make these purchases. You mentioned that you have uninstalled iTunes before, but if you didn't follow this guide exactly, uninstalling iTunes and all of its components in the order specified, it may not have been successful so you should try again: Windows XP or Windows Vista/7.
