Server :: OEL 5.5 And Oracle 10.2.0.5 Low Decrease Of Memory?
May 13, 2011
I have an issue with few servers. All have OEL 5.5 and various versions of oracle (mainly 10g something).
I've noticed on one machine that amount of free memory is slowly decreasing. When it comes to less then 30M, application has problems. Ive tried adding mem on this machine (virtual), and it behaves the same.
The same is on physical machines I have simmilar, if not the same config. Variations are with physical memory installed, and it does not matter if servers have 2G, or 8G, free -m gives around 30 free
It does not swap, and does not make some big issues on other machines, but on this one, application that uses this DB timeouts the user. Is there some chance to check what is creating this issue?
P.S. I've tried with DB admin to check something related to oracle itself, bit when we shutdown instance, Oracle frees 1.5G allocated to him, but nothing else. Will try testimg a bit more, but any thought on this is usefull. This is production server, so no big issues can be done. Will try to copy it to other hardware and do some testing, but then no App server available to attack it.

I'm trying to install oracle (11g R2) on my OpenSuse (11.3), but when I do startup nomount, I got an error:
ORA-00854: MEMORY_TARGET not supported on this system
On web, I found that I need to increase tmpfs because of my memory_target oracle init parameter. I do it with:
mount -t tmpfs shmfs -o size=3G /dev/shm
(previous value to tmpfs (df -h) is 2G).
After that 'startup nomount' runs well, but after reboot, values are the same. So, how to 'save' this new value?

we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

I've AMD64 system with Ubuntu 11.04 installed. It's been rough ride for me to install oracle-xe-universal. I've already spent more than 2 days on this. Still unsuccessful.
1) First I downloaded the packages libaio_0.3.104-1_i386.deb and oracle-xe-universal_10.2.0.1-1.1_i386.deb
2) Then I ran
sudo apt-get install bc (ran fine)
sudo dpkg -i --force-architecture libaio_0.3.104-1_i386.deb (ran fine)
sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb
(gave me dependency error for libc6 (>= 2.3.2), I modified the control file to remove dependency and rebuilt the package) (now worked fine) Oracle xe is now installed. Then I tried to start the DB it started but it's HTTP client never started. So I decided to uninstall the oracle-xe=universal. None of the sudo apt-get remove oracle-xe-universal command's didn't worked for me. So i went for manual uninstallation directions as per oracle link.
I ran the following command-
--Manually uninstalling Oracle 10g--
sudo rm -rf /usr/lib/oracle /etc/oratab /etc/init.d/oracle-xe /etc/sysconfig/oracle-xe /usr/share/doc/oracle_xe /usr/share/doc/oracle_xe_client
Then I again ran the following command to install oracle-xe
sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.0_i386.deb
See below what I got as the output-
rocky@ubuntu:~/git/mygit/edas2/libaio$ sudo dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb
dpkg: warning: overriding problem because --force enabled:
package architecture (i386) does not match system (amd64)
[code]....
Even in applications menu I don't see the if oracle has been installed. So i conclude first time installation was ok but somehow http client didn't worked. After manual uninstallation, second installation didn't even loaded/installed the oracle-xe in init.d directory.

I have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.

I am running a 5 node 11g RAC cluster with cluster ready services. The hardware is HP BL460g6 with virtual connect modules on each chassis. The OS is RHEL5.5, 2 Qlogic 4G fibre cards, 2 Broadcom NICs bonded, and the backend disk is all Hitachi 15k. The issue that I'm seeing is periodically each day there are spikes in I/O waits for disk writes, and sometimes that will cause a node or 2 to reboot when CRS can't communicate with the other nodes. Both nodes that have been evicted, are on the same chassis. What I've checked is, the backend storage is not seeing ANY high utilization, in fact it's running at less than 10% all the time. The network is 10G, and is not showing errors on the switch, or on the blades themselves. The redo logs have a 10M buffer cache, and are running on ASM disk. What other information would be beneficial to check? I am seeing nothing in the logs as to any errors, or waits for disk writes. I believe it's a software issue, but am lost as to how to prove it. These aren't the only nodes experiencing periodic high I/O waits, and it happens at the exact same time on all systems, whether they run ASM or are part of a cluster.

I have a query regarding top & virtual memory. When we run top it show VIRT (Virtual Mem), RES (Resident Mem) & SHR (Shared Memory). The total virtual memory of my machine is 4 GBs (2 GB RAM + 2 GB Swap), but still I am able to see a process showing 4000m virtual memory column. what it means, as its show VIRT Mem more than actual available VIRT memory

I just found that PMON and SMON are running (i.e., showing in the output of ps -ef | grep -i [o]ra)but when I check MMAN (used for internal database tasks), nothing comes up:
Code:
ps -ef | grep -i [m]man
Is that okay or could there be some problem?
So, what are the essential processes of an Oracle Databse that we must check for their status to make sure that the Oracle Databse is up and running fine? What steps do you usually take to validate an Oracle Databse on a Unix / Linux (Production) Server (specifically immediately after a CR has been worked upon)?

I am not an oracle DBA, but need to find the cause of high load avg, even after adding more CPU power the load avg is the same.
Old and new servers load avg is the same (between 6-10 peak hours and 3 to 5 during off-peak hours) no difference. I expected the laod to come down as we added more CPUs.Our DBA says queries are optimise.Can some Oracle DBA give some tips to find the cause.

We have a Wipro Net Power 8552 server on RAID 5 with Linux Advanced Server. The Databse is Oracle . Every time the reocovery is made the block corruption error gets changed. There are four hardisk in the Raid with 18 GB capacity of Quantum make. I want to make sure if any Utility is there in Linux to check the Harddisk if any Block corruption is there or Not.

I am going to install Oracle RAC on two Servers, With shared SAN storage (Servers and Storage is IBM) OS = RHEL 5u5 x64 bit
And we used multipathing mechanism and created multipathing devices. i.e. /dev/mapper/mpath1. Then I created raw device /dev/raw/raw1 of this /dev/mapper/mpath1 Block device as per pre-reqs for Oracle Cluster. Every thing looks good, But we faced the performance issue as under.
when we run command :
#dd if=/dev/zero of=/dev/mapper/mpath1 bs=1024 count=1000
the writing rate is approx. 34 MB/s
But If we run command
#dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=1000
the writing rate is very slow like 253 KB/s

I need to check with nagios an oracle database that is located on a server. There are a lot of plugins that are provided, the problem is that the database is located on a remote server (i have an hostaddress) and then i need to log on the database (i have username and pass)So i only need to have a plugin that connects to that hostaddress and logs on, but i can't find any plugin which does that

We have a Dell PE6600 with a QLA2460 FC HBA in it. Server is running RedHat AS 4.7 (kernel 2.6.9-78), FC driver used is the file qlafc-linux-8.02.23-3-install.tar downloaded from the QLogic website. On this server is an Oracle database running (11.1.0.6). Files for the Oracle database are located in mountpoint /u02. The SAN is an iQStor 2880. Since several weeks we suddenly have problems with the Oracle database after a reboot of the server. After a reboot the mountpoint /u02 is readable and writable (tested by creating, opening and removing files).
However, when we try to start the database we get an error which give you the idea that the database is corrupt. The Oracle error is quite a general error. After doing a lot of testing we found out that if we unmount /u02 and mount it again (using mount -a so it reads the /etc/fstab), the database can be started after all. So the database is not corrupt but for some weird reason we have to remount /u02 first before the Oracle database can use it. We don't know if it's a linux issue, fibre issue, san issue or an oracle issue.

I'm trying to decrease the tcp TIME_WAIT state which, from what I understand, occurs on the host that initiates the closing of a socket by sending a packet with the FIN bit set. Most people say to change /proc/sys/net/ipv4/tcp_fin_timeout to a lesser value. I have tried this many times and it makes no difference. The TIME_WAIT's still linger for ~ 60 seconds. This link says that it actually adjusts the FIN-WAIT-2 state and I think they're right.[URL]
Quote:
/proc/sys/net/ipv4/tcp_fin_timeout
Time to hold socket in state FIN-WAIT-2, if it was closed by our side. Peer can be broken and never close its side, or even died unexpectedly. Default value is 60sec. Usual value used in 2.2 was 180 seconds, you may restore it, but remember that if your machine is even underloaded WEB server, you risk to overflow memory with kilotons of dead sockets, FIN-WAIT-2 sockets are less dangerous than FIN-WAIT-1, because they eat maximum 1.5K of memory, but they tend to live longer. Cf. tcp_max_orphans.
Here's what the netstat man page says about these two different states:
Quote:
TIME_WAIT
The socket is waiting after close to handle packets still in the network.
FIN_WAIT2
Connection is closed, and the socket is waiting for a shutdown from the remote end.
how to actually decrease the TIME_WAIT state?

Last weekend i've set up my first headless ubuntu home file server and torrent downloader with ubuntu 9.10.Very cool but CPU is way too fast for a home server: P4 HT 2.8Ghz, unfortunatly it has only 256Mb of ram, so no X server and no VNC (old HP office pc) At the moment memory usage is only 40Mb without X server. Besides SSH works just fine Few questions i can't seem to find answers to on google:What is a good CL network monitoring program?mething similar to htopUbuntu 9.10 has a lot, about 20-30, console-kit deamon instanses running after boot each using some memory that i can't spare.
