OAS 4.0.8.1 wrksf taking all CPU

Hi,
My configuration is: NT SP6a, Oracle 8.0.5, OAS 4.0.8.1. All running on the
same server. OAS and Oracle 8 are in the same ORACLE_HOME. Whenever I
start OAS from the admin site, the WRKSF (catridge server) process takes up
100% of the CPU.
Could someone advice me how to trouble shoot this. Is there a fix? Pls ask
me more info if you need to.
Thank you so much.

My experience with wrksf, on Mandrake 7.0 (RH 6.1+) is that wrksf starts at first, then bails after about a second.
I have a couple cartridges installed, C and Perl, and it starts those cartridges up and then fails. I don't get the same error message that you do, but there is an error in the wrb.log:
`OWS-10911: Throwing exception for reason: wrkpGetProperty 2 `
`OWS-04793: Operation oracle_OAS_System_CartridgeServerFactory_create_nwreturns exception IDL:omg.org/CORBA/UNKNOWN:1.0 `
I'm not sure what this is all about, but it does start up my cartridges at first, because I specified a mininum number to start up initially, and a minimum number of instances.
They just don't come back if terminated, since wrksf isn't there.
BTW, this is the same error I encountered when, on NT, I compiled a c cartridge with Metroworks CodeWarrior instead of MS Visual C++ v6.0. So I wonder if this has something to do with compiler incompatibility, if wrksf was compiled with a different compiler from the rest of OAS. While compilers don't usually matter for C, they do for C++, and all binaries and libraries must be compiled with the same compiler/linker to work together.
Just a stab in the dark.

Server Process taking all CPU time intermittently on Solaris

Hi,
What does my program do :-
We have been facing this problem from many days, We have a server
process which is continuously listening at a port on Solaris 5.8.
Whenever a request is sent to this server a new thread & a socket is created for that client.
This process is running as a proxy server, which connects to some other machine on client request.
Problem:
The process start taking whole CPU after few days, happens in a weeks
period. The process remain in this state for few hours & after that it
stops responding to any requests.
& the only thing which can be done, to make it work is to restart the
process.
If someone has faced a similar problem then please let me know if you
have found a solution for that.
I will give 10 duke dollars to you if you can provide a solution for this problem.
Regards,
Sachin

Wbengine.exe taking all CPU

Im having issues with wbengine.exe I know its the block level backup for WSB however its killing my server (see below) we are running on 2 x 600gb R1 SAS 15k disks for where the os VM is stored and 3 x 1tb nearline 1tb disks 7.2k where the data for essentials
("server folders/folder redirection" is stored with another virtual server doing very little in the background there is plenty of memory and cpu for all vms (just the two)
we have a backup on the vm start at 8 and finishes around 10 and a host backup that starts at 11 and finishes around 1
backups locally from WSB dont show to of started however they did on the host with warnings any ideas ?
UPDATE:
After talking to some users the issue occurred on yesterday morning, it looks like WSB is causing issues backing up when on schedule, as looking at the CPU usage from 8 at night last night. Thats when it started maxing out and the backup began, a single
one off backup seems to work fine using the settings of the schedule but scheduling seems to kill it.
To note this is going through ISCSI

TS3276 my smtp server shows offline. I've tried taking all accounts offline and then back on with no effect

email was working fine and then I couldnt send mail from my bellsouth.net account. The smtp server is (offline). I tried taking all accounts offline and then back on. This didn't help.
I can send email from my iphone or webmal on my windows based desktop.
Any suggesstions? I'm not a very experienced Mac user.

What were the results of taking all the applicable steps in the support article?

Checkbox taking all the records irrespective of selection

HI All,
This is my code
for i in 1..htmldb_application.g_f02.count
loop
insert into nam values(htmldb_application.g_f02(i));
end loop;
Here i'm trying to insert the selected things but its taking all the records whatever is displaying in the report
Kindly help me to get rid of the issue
And guide me how cai insert only checked in records

hi
I'm not a pro but maybe I can share some experience.
First I would create a textfield for debugging.
This helps to find out what data you are really working with.
My textfield's name is "PX_SELECTED_ITEMS"
I filled the textbox with a process in "On submit - After Computations and Validations"
BEGIN
:PX_SELECTED_ITEMS :=
    HTMLDB_UTIL.TABLE_TO_STRING(HTMLDB_APPLICATION.G_F01);
END;I'm not sure how your values are seperated.
In my application I hat to replace the seperator from ':' to ','
Therefore I created another textfield "PX_SELECTED_ITEMS_replaced"
and added following code to the process:
:PX_SELECTED_ITEMS_replaced := replace(:PX_SELECTED_ITEMS,':',',');Now I have two textfields wich should contain your selection.
The second one ("PX_SELECTED_ITEMS_replaced") with the comma seperated data should be good for a "where-filter" in an SQL statement.
Here is the PL-SQL-syntax I used for a standard SQL report:
declare
v_sql varchar2(32767);
begin
v_sql := 'select * from my_table';
if :PX_SELECTED_ITEMS_replaced is not null then
    v_sql := v_sql ||' where My_ID in ('||:PX_SELECTED_ITEMS_replaced||')';
else
    v_sql := v_sql ||' where 1=0';
end if;
return v_sql;
end;This Report should contain your selected items.
Note: This does NOT work with Interacive Reports.
I hope this helps you finding the issue.

My iPhone 6 plus is a 16G, and my photos and camera is taking all my storage. Does icloud keep my photos in tack, if I delete them off my phone?

I have an Iphone6 plus and my photos are taking all my storage. I can't update or download anything, what to do?

Actually iCloud doesn't keep your photos until you back up your iPhone to iCloud: tap Settings > iCloud > Backup > enable Backup and tap Back Up Now. However, I have to tell you that iCloud backup file only contains your photos on your iPhone Camera Roll and can't be viewed unless you restore your iPhone with the backup file. For photos in Photo Library, you need to find a third-party tool to copy them to your computer. In a word, in my opinion, you'd better import photos to your computer: Import photos and videos from your iPhone, iPad, or iPod touch to your Mac or Windows PC - Apple Support

Procedure is taking 100% cpu

Hi ,
One of my procedure is taking 100% CPU, I looked execution plan .. But I am not sure what to look on that .. I didn't find any anything wrong in execution plan. like all are index seek .. Even the query is not taking much time just 2 sec
Regards Vikas Pathak

In addition to great suggestion Sean has been posted , I always start with the below
---This first thing to check if CPU is at 100% is to look for parallel queries:
-- Tasks running in parallel (filtering out MARS requests below):
select * from sys.dm_os_tasks as t
where t.session_id in (
select t1.session_id
from sys.dm_os_tasks as t1
group by t1.session_id
having count(*) > 1
and min(t1.request_id) = max(t1.request_id));
-- Requests running in parallel:
select *
from sys.dm_exec_requests as r
join (
select t1.session_id, min(t1.request_id)
from sys.dm_os_tasks as t1
group by t1.session_id
having count(*) > 1
and min(t1.request_id) = max(t1.request_id)
) as t(session_id, request_id)
on r.session_id = t.session_id
and r.request_id = t.request_id;

Any particular reason why you have a non-default value for a hidden parameter, optimizercost_based_transformation ?
On my 10.2.0.1 database, its default value is "linear". What happens when you reset the value of the hidden parameter to default?

F1 live timing taking 100% CPU

I realise this is a pretty obscure problem. F1's live timing service runs as a Java applet in a browser: http://www.formula1.com/services/live_t … popup.html (registration required, but it should load and run at any time, not just on race weekends). Obviously, I haven't used it since last October, and when I fired it up this weekend it just sat there, taking 100% CPU.
It doesn't seem to be the JVM at fault: other Java applets run fine, and I've tried downgrading to a version I know worked last year. Neither is it anything in the applet itself: I have another Arch partition which I cloned off this one last November, and it works perfectly there (it doesn't seem to be the kernel, either; I tried booting this "current" partition with the kernel from that one). However, so many packages have been upgraded - and I've tinkered so much with this install - since then, that it could be literally anything.
For that reason, I don't expect anyone to come up with an immediate answer, but I'd appreciate some ideas on how to narrow down the possibilities and figure out what might be causing this.

Ifweb60.exe takes all CPU on webserver-Forms Prod. mgmt

I have 3 tier setup. Database 81741 on windows2000 SP3. Webserver on windows2000 SP2 using forms6i patch 11(6.0.8.20.1). Clients using IE5.05/IE6 to access database. Sometimes, a user hangs the process and kills his session from his PC, even reboots client. The process is still there on webserver and goes on taking more CPU and more memory till it cloggs the webserver. It has taken almost 100%CPU. How can we eliminate this process without rebooting the webserver.
I tried killing the session from the database end, it is still there on webserver. The user says he waited for 2 mins to respond the application and then killed using ctrl-alt-del. Is there a way to kill the session on the webserver. When we try killing using Task Manager, it says 'access denied' and wouldn't let us kill. Even, tried with FORMS60_TIMEOUT. IN normal situation, this worked but in this case where a application hanged & user killed, FORMS60_TIMEOUT even didn't kill the process ifweb60.exe.
Someone has a idea how to prevent from rebooting webserver again and again...other than to check all 100 forms for any infinite loops and fix that.
Thanks a lot.

I believe this is a known bug.
As a work-around you could try to add FORMS60_CATCHTERM=0 to the registry.
This probably will cause Dr. Watson on the webserver box, but should kill the process.
Slava.

[SOLVED] mandb hangs, taking 100% CPU

I have a VPS running Arch (limited to kernel 3.9.4-1 by the provider). The system was unceremoniously rebooted last night due to a power outage at their facility. When it came back up, the mandb process being run by cron was taking 100% of the CPU and had been running for ~10 hours by the time I noticed it.
I eventually killed the mandb process and re-tried it manually with debugging turned on: `mandb -d`. It appears that processing stops at /usr/share/man/man5/core.5.gz (this is the last output I see, even if I leave it running for an hour or two). Even after the output stops, it is still taking 100% CPU. Anyone have any ideas or other things to try debugging it? I'm all out.

I re-installed man-pages with `pacman -S man-pages` and then received the following messages:
Purging old database entries in /usr/share/man...
Processing manual pages under /usr/share/man...
Updating index cache for path `/usr/share/man/man2'. Wait...mandb: bad fetch on multi key alarm 2
mandb: index cache /var/cache/man/3354 corrupt
Then, after running
mandb -c
subsequent calls to `mandb` executed successfully. Problem solved. I guess maybe mandb was running when the power outage occurred, corrupting the man index cache... makes me wonder what else got corrupted that I haven't noticed yet.

Non interactive zlogin eats up all CPU on Solaris 10 u4

Hi,
We are having trouble with a zlogin command that is started via a script from inittab on a Solaris 10 u4 system.
When a zlogin command is started from the script this zlogin will within 10-15 seconds start spinning and consume 97-98% of the CPU. The zlogin command never ends, and the startup is stuck there.
Running a pstat during the zlogin shows the following picture:

_exit(0)When running the process under truss the zlogin runs to end, probably because the child processes now get time for doing their work.

Found the reason. The default scheduling class was set to RT. Probably explained why zlogin was allowed to eat up all CPU resources

Oracle internal queries taking more CPU time

Hi,
Following are queries taking more CPU time. I got this from awr report. Can anyone tell me why these queries are running? Is it a oracle enterprise manager query? should I use
emctl stop dbconsole to stop this?
DECLARE job BINARY_INTEGER := :job; next_date DATE := :mydate; broken BOOLEAN := FALSE; BEGIN EMD_MAINTENANCE.EXECUTE_EM_DBMS_JOB_PROCS(); :mydate := next_date; IF broken THEN :b := 1; ELSE :b := 0; END IF; END;
SELECT COUNT(*) FROM MGMT_METRIC_DEPENDENCY_DETAILS DEP, MGMT_SEVERITY SEV WHERE DEP.TARGET_GUID = :B5 AND DEP.METRIC_GUID = :B4 AND DEP.KEY_VALUE = :B3 AND DEP.EDEP_TARGET_GUID = SEV.TARGET_GUID AND DEP.EDEP_METRIC_GUID = SEV.METRIC_GUID AND DEP.DEP_KEY_VALUE = SEV.KEY_VALUE AND SEV.COLLECTION_TIMESTAMP BETWEEN :B2 AND :B1
SELECT CURRENT_STATUS FROM MGMT_CURRENT_AVAILABILITY WHERE TARGET_GUID = :B1
Thanks in advance

Hi,
maybe this document will help if you are using 10g:
SQL run by SYSMAN consuming a lot of resources on OMS with 800+ targets [ID 330383.1]
https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=PROBLEM&id=330383.1
there you'll find Cause and Solution too:
SYSMAN Job and Queries are Taking Up High CPU (DB Console) [ID 1288301.1]
https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=PROBLEM&id=1288301.1
For databases above version 11.1 there are paches available.
Best,
