There are two VSP machine (pst001 and pst002)

Each VSP machine running with 2 hpvm configured in cluster

HPVM version is 4.30

Now I need to move the ipt001 from pst001 to pst002.

commands are same as moving one package from one node to other node.

please confirm if my steps are correct.


#cmhaltpkg -v -n pst001 ipt002

#cmrunpkg -v -n pst002 ipt002

WIll those above works or any other commands to move hpvm from one node to other node.

Hi ,

 

One of our new Storage XtremIO had a test lun on it , and suddenly on 11iv3 it showed 

bdf:I/O error /test

 

What could be the reason ?

Storage team saying they didnt do anything , HP team saying they had unpresented a lun which throwed following message in syslog ;

HPUX root password recovery

Hi,

 

I need to recover root password of rx4640

I tried booting in single user mode but asks password there also since it's trusted system

Later booted the server using recovery CD but coud not run chroot /ROOT /sbin/sh because root partition was not mounted correctly.

 

Is there any way we can recover the root password

I need to change the disk timeout for raw device. Is there a way to change that? For device managed via LVM we can change that using pvchange command but I couldnt find equivalent command for raw device which is not managed via LVM

HPUX 11.31 with Oracle 11g (running ASM) high memory usage

$
0
0

Hi all,

We have a new rx2800 i4 with 128GB physical memory running HP-UX 11.31 and Oracle 11g (running ASM). We've recently seen high memory usage through glance  consistantly running at about 99%. Given that this is a 128GB system, running at 99% of the available physical memory makes me a little uncomfortable (though I'm not getting any page outs)

 

Now in glance I see 55GB being used by File Cache which seems to be at the root of the problem. My filecache_max setting is at the default since I read that it should probably be left at its dynamic setting and to let HP-UX manage itself. However, I believe that can also allocate up to 50% of the physical memory which certainly seems to be happening in this case.

 

 

So given the KCTUNE output below, do you folks think that I should perhaps shrink the filecache_max setting and restricting this number to say 20% or so? I'm coming from HP-UX 11.11 so this tunable is a bit new to me.

Any other suggestions based on my kctune below?

 

Incidently after a little more research, I found the following document which seems to support my thinking of shrinking filecache_max...but I would like some input as well.

 

http://support.hp.com/sg-en/document/c01646142

 

As always thank you in advance, and any input will be greatly appreciated (and kudos awarded of course).

 

Thanks

Mauro

Why is DISPLAY variable sometimes simple and others FQDN

$
0
0

I have 3 HP-UX 11.31 virtual machines - in theory set up identically ('in theory').

On 2 of them when I log in from my PC using Exceed Xterminal emulator, they report the DISPLAY variable as 'fred:31.0', but on the other machine it is reported as 'fred.domain.co.uk:40'?

 

Please note it is the fact that 2 are reporting simple names and the other a FQDN that I am querying, not the 31/40 difference.

 

Note also that /etc/nsswitch.conf, /etc/resolve.conf and /etc/hosts are the same on all 3 machines.

 

What I really want to do is is find out why the 3rd machine is reporting a FQDN and fix it so that it reports a simple name like the other 2 (I don't want to work around this problem by putting code in my .profiles).

 

Many thanks,

 

Gary


Recommended syslog.conf settings when using opcle / OVO software? Too many events

$
0
0

Our organization is using HP-UX / Solaris with OVO software and the java-based message browser.

 

Our syslog.conf on managed nodes is currently set to *.info;mail.none for opcle-monitored logs.

 

What we frequently see is several thousands (sometimes hundreds of thousands) of events for single system issues (a disk failure for example.)

 

This makes it difficult for our operations teams to manage the events coming in.

 

I've searched the net for recommended settings / best practices but haven't found anything so far.

 

Ultimately, we want to see errors or warnings, but we don't need 1000 events for a single issue.

 

Can anyone provide some insight?

 

Thanks in advance

Performance Issue App -DB diff Server/Storage

Hi ,
&nbsp;
We have environment where we have 3 App ( hpux 11iv3 ) &amp;&nbsp;2 DB Servers ( hpux 11iv3 ) all 16cores / 256GB Ram.
We did our POC of XtremIO Storage on Single Report Server ( hpux 11iv3 , 16cores , 256GB RAM ) for DB luns and for app luns on same server from VNX5500 Storage
We ran batch job which took 18 min to complete on that Single Report Server .
But wehn we migrated to Prodcutin on XtremIO ( 1 DB &amp; 1 App server ) the same batch job completed in 35 min.
&nbsp;
Note : We ran the batch job when no other processes were running on Production ( Same as Single Report Server )
What could be the reason ?&nbsp;
Is it because here we are having 2 storages on 1 single server we are getting performance ??
Whereas in Production we have 2 Storages on &nbsp;two servers , hence there is dip in performance ??
&nbsp;
Network is coming in picture ??
Oracle 11g db , hpux 11iv3 .

label printer gets disabled immediately after being enabled

$

OS: HP-UX  B.11.11 (Wildebeast)

Printer: Intermec PF8t (labels)

 

Immediately after an 'enable', printer is briefly enabled then becomes disabled with no intervening print job. Jobs remain in queue. Attempted again after jobs cleared from queue, same result.

 

Printer was added to the spooler as a network printer. Spooler was restarted.  Other printers are functioning.

 

Printer successfully executes test print cycle. Printer is pingable.

 

Verified configuration is the same for other functioning printers of the same model in HP Web JetAdmin and via telnet.

 

'lpstat -p' gives 'reason unknown' and fence priority of 0.

 

Any advice is appreciated.

NTP Client Configuration

$
0
0

Hi,

 

Need your help please!!

 

We have the Windows Domain Controller as NTP server for time sync and need to configure NTP client in HP-UX servers.


Production Environment Deatails.

Oracle 11g RAC running on two nodes (Time dependent, should i need to stop the database before configuring ntp client?)
HP-UX 11.31 (two servers)

 

On both servers date is same where as the clock of these two servers is 20 minutes ahead from NTP Server.

 

[mcmsdbl1@oracle@/u01/oracle]$date

Mon Sep 7 08:29:47 WAT 2015


I got the below message on checking if NTP is already configured

 

[mcmsdbl1@root@/]#ntpq -p

ntpq: read: Can't assign requested address

 

Whereas on checking service it shows running..


[mcmsdbl1@root@/]#ps -ef | grep xntpd

root 21276 21177 0 08:45:12 pts/0 0:00 grep xntpd


Do i need to configure NTP Client on both servers? or only in one server will be enough because both servers is synchronising the time with each other as shown below the message from /var/adm/syslog/syslog.log


Time is syincronizing with in both nodes in cluster

p 6 14:37:53 mcmsdbl1 CLSD: The clock on host mcmsdbl1 has been updated by the Cluster Time Synchronization Service to be synchronous with the mean cluster time.

 

If i have to configure NTP Client in one of the server then Will follow the below steps, please check and advice if am i missing any steps.


-- Shutting down the database first before proceeding further----

 

The configuration of /etc/ntp.conf file as below,

 

server 10.10.xx.xx prefer           #NTP Server IP-Address

fudge 127.127.1.1 stratum 10 # localhost if NTP servers fail

driftfile /etc/ntp.drift


The configuration of /etc/rc.config.d/netdaemons file as below,

export NTPDATE_SERVER=10.xx.xx.xx     #NTP Server IP Address
export XNTPD=1
export XNTPD_ARGS=


And running the xntpd daemon manually. #/sbin/init.d xntpd or /sbin/init.d/xntpd start and Wait. 

 

Then will check the ntp sync status

 

ntpq -p

Syed

We have app & DB setup on same subnet/vlan .

OS hpux 11iv3 , 16cores , 256GB RAM , rx2800i4 .

When we are running batch code on App , we could see that there is performance issue on DB Server .

( Batch job taking more time to complete , than when it is ran when both app and DB are on same server )

Parameter : forking more parallel processes

  1. parallel_max_servers database parameter should be set to value 160 instead of 16.

Oracle default value for this parametere is CPU_COUNT x PARALLEL_THREADS_PER_CPU x (2 if PGA_AGGREGATE_TARGET > 0; otherwise 1) x 5.

In our case, CPU_COUNT is 8, PARALLEL_THREADS_PER_CPU is 2, PGA_AGGREGATE_TARGET > 0, hence we need to multiply by 2.

Hence value for this parameter should be, 8 X 2 X 2 X 5 = 160

 

--------------

 

OS version : HPUX 11i v3

model :BL 870c i2

server is configured as HPVM.

 

Can you please tell me if above oracle parameter change can be applied in HP UX.

When I google it,Oracle docs says it is OS dependant.

default value is 2.

Does HP UX supports those field.

what are the parameters in OS that are related to those Database parameters.

 

How to find does this model supports PARALLEL_THREADS_PER_CPU

 

 

 

Check iops for a particular filesystem

Hi ,

 

Is there any way by which i can check whether this filesystem /test1 is delivering so much of iops which is coming from Storage A , rather than a filesystem /test2 which is coming from Storage B.

 

How can we check iops at filesystem level through sar , etc .

Please provide steps to extend logical volume and file system from 8GB to 15GB. I do not have online JFS.

The system is HPUX 11.31 rx2660 itanium.
