11gR2 on Solaris and Veritas DMP

I am in the process of building a 2 node cluster to test some upgrades we have coming up. Our current clusters are using Veritas for the clustering software. For this new cluster ( 2 new machines ), we want to use 11gR2 clustering and ASM.
My question is this:
We want to take advantage of the Veritas multi-pathing ( DMP ). In 1 document I have read, it says that "ASM disks must be configured as logical volumes to utilize DMP multipathing. ASM must us the dmp device which resides over the vxvm logical volumes: /dev/vx/rdmp/cxtydzsx"
One of my problems is that all of the devices under /dev/vx/rdmp are owned by root. It is my understanding that in order for ASM to see them, they need to be owned by grid:asmadmin. Just on a whim, I chown'd all of those devices to grid, but that change isn't persistent across a reboot.
My other problem is that my second node doesn't see the diskgroups/volumes I created on the first node. The second node can see the same disks, just not the diskgroups/volumes. I have been told that in order to see the diskgroups and such on the second node, they will have to be deported from node 1 and imported on node 2. That makes sense. We can't import them shared because we don't have the clusterware installed yet.
All of these disk devices are raw and don't have any type of filesystem associated with them. I was able to form a cluster with 11gR2 before, but that was by pointing directly to the block device under /dev/rdsk/cxtydzsx, but that didn't provide any type of multipathing protection. The disks are luns being presented from an EMC CX480, and the same luns are presented to both nodes.
I'm not finding the provided documentation very clear as to how exactly I need to setup the disks and what I need to do to get DMP working.
Any advice would be appreciated

Ended up using EMC Powerpath. It was much easier and worked like a champ the first time. I didn't have to fiddle with creating diskgroups and logical volumes, just changed the permissions on the /dev/rdsk/emcpower* devices to grid:asmadmin, ran them through format to build partitions that start at cylinder 1, and the installer picked them up right away.

ZFS and Veritas DMP

Does anyone know whether ZFS is supported on DMP devices on Storage Foundation 5.1
It is not supported on Storage Foundation 5.0 MP3 but I was wondering if it had been introduced
for 5.1
http://seer.entsupport.symantec.com/docs/324001.htm
The 5.1 documentation is not clear as to whether it is supported or not.

Setting up Veritas DMP with a 6140...

Hello!
I'm somewhat experienced with StoreEdge 3510 Arrays and can set them up in my sleep, but I'm having no luck when it comes to setting up Veritas DMP with a 6140 I've somehow become responsible for configuring. Does anyone have any information on ensuring the 6140 array is configured properly so vxvm DMP functions? I've got the luns configured, the host all cabled up, and the luns under vxvm control on a Sun V440 with Solaris 10. I can see the luns, write data to them, but I can't seem to collect the information needed in order to have DMP function. As such, the vxdmpadm command only shows one path to the array despite having four physical FC connections between the 6140 and the V440 server.
Any help is greatly appreciated! I'm sure I'm just "missing something" since this is new hardware to me, but I can't seen to find out what.

All the 6140 setup documentations are on www.sun.com/documentation/.
There is no special step as long as you have a qualified version (for 6140) of VxVM and you install the correct ASL.
At this point, you will need to create the initiators using CAM, with the right host type. In CAM you can select different host type, this defines how the 6140 f/w has to behave when there is failover.
If you use VxVM on the host and DMP, you have to use the host type Solaris DMP for your initiators, at this point the 6140 f/w will not that AVT (Automatic Volume Transfer) has to be turned ON.

WebStart Flash and Veritas Volume Manager

I would like to use WebStart Flash for backup of the system
disk. The goal is to be able to recover the system disk rapidly.
It works perfectly for systems without Veritas Volume
Manager on the system disk.
However, if Veritas Volume Manager is installed and used
for mirroring the root disk, the system is not able to boot using
WebStart Flash. This is probably because the "private region"
of the disk is not included in the flash archive.
Does anybody have a solution for this, or does any of
you successfully combine WebStart Flash and Veritas
Volume Manager?
I use Jumpstart and the install_type is configured to
flash_install.
The question was also asked in the newsgroup
comp.unix.solaris.
Rgds,
Henrik

For many reasons, today you cannot save the VxVM
private region information as an implicit part of a
flash archive. The procedure would likely be to
unencapsulate the root drive, create the flash archive,
then re-encapsulate the root drive. This is an ugly
procedure and may cause more pain than it is worth.
When a root disk is encapsulated, an entry is put
into the /etc/system file which says to use the VxVM
or SVM logical volume for the rootdev rather than
the actual device from which the system was originally
booted. When you create a flash archive, this modification
to the /etc/system is carried along. But, when you install
it on a new system which doesn't have VxVM properly
installed already (a chicken-and-the-egg problem)
then the change of the rootdev to the logical volume
will fail. The result is an unbootable system (without
using 'boot -a' and pointing to a different /etc/system
file like /dev/null).
The current recommended process is to use a prototype
system which does not have an encapsulated root
to create the flash archive.
VxVM also uses the ELM license manager which will
tie the VxVM runtime license to the hostid. This makes
moving flash archives with VxVM to other machines
impractical or difficult.
The long term solution would be to add logical volume
management support to the JumpStart infrastructure.
I'm not counting on this anytime soon :-(

Sun c4 and veritas netbackup 6 mp4 installation

Hello, please help me!
We have SAN with 2 st6140 and 3 broacade 200e switch. One site is: two 200e and 3 linux hosts, other site is: v240 server (one FC port) with solaris preinstalled and installed Veritas NetBackup mp4, 1 200e switch, Sun C4 library whith FC ports.
On second site I connected C4 FC host port to the 200e swith, FC port on v240 also connected to the 200e switch.
Can you describe me a common porcedure to configure correctly a server with Veritas and C4?
I cant add "device" in veritas Administration console now, because it cant see nothing.
How i have to connect C4 and Veritas server to SAN correctly ?

create a soft zone on your brocade , with your C4's FCs ports and your Netbackup Master server, for Netbackup use version 6.5 , not 6.0
once you activate your zone, run cfgadm -al -o show_FCP_dev, you should be able to see your paths, one path or more paths from your server, two or more from your C4 libraries' fabrics, netbackuop 6.5 is very clean and installed , to be able to recognize your drivers ...once the software installed, go to your GUI, to configure device...
Also, use the latest version of Solaris10 on this..it is much cleaner to work with netbackup 6.5

Why difference in Solaris and Linux

Hi,
The following program is giving results diferently when I am executing using g++ compiler in Solaris and Linux.
Why it is so.
here is the code:
#include <stdio.h>
#include <string.h>
#include <malloc.h>
#include <stdlib.h>
int main( void )
size_t size;
char *buf;
if ( ( buf = (char *)malloc(10 *sizeof(char))) == NULL)
exit (1);
size = sizeof( buf );
strcpy(buf, "HelloWorld");
printf("\n Address is : %u String is : %s size : %d ", buf, buf,size);
if (( buf = (char *) realloc(buf, sizeof(20))) == NULL)
exit ( 1);
*(buf+10) = 'A'; *(buf+11) = 'B'; *(buf+12) = '\0';
printf("\n Address is : %u String is : %s\n", buf, buf);
free( buf);
exit( 0 );
Solaris:
Address is : 134160 String is : HelloWorld size : 4
Address is : 135704 String is : HelloWor
Linux:
Address is : 134518824 String is : HelloWorld size : 4
Address is : 134518824 String is : HelloWorldAB

Hi,
The following program is giving results diferently
when I am executing using g++ compiler in Solaris
and Linux.
Why it is so.
here is the code:
#include <stdio.h>
#include <string.h>
#include <malloc.h>
#include <stdlib.h>
int main( void )
size_t size;
char *buf;
if ( ( buf = (char *)malloc(10 *sizeof(char))) == NULL)
exit (1);
size = sizeof( buf );The size you get here is the size of buf, which is the size of a pointer, not the size of what buf points to. sizeof(*buf) would give you size of a char, the type (not the object) that buf points to.
There is no portable way to find out the number of bytes allocated on the heap if you are give only a pointer to the memory. You have to remember the size some other way..
strcpy(buf, "HelloWorld");A literal string consists of the characters in the string plus a terminating null, all of which are copied by strcpy. You allocated 10 chars for buf, but are writing 11 chars into it. At this point, the program has undefined behavior. Literally anything at all could happen, because you can't predict the effect of writing outside the bounds of allocated memory.
printf("\n Address is : %u String is : %s size :
e : %d ", buf, buf,size);
if (( buf = (char *) realloc(buf, sizeof(20))) == NULL)The "sizeof" operator in this case is returning the size of the type of a literal 20, which is an int. If you want to allocate 20 bytes, you write 20, not sizeof(20).
exit ( 1);
*(buf+10) = 'A'; *(buf+11) = 'B'; *(buf+12) == '\0';SInce you can't count on buf having more than 4 bytes at this time, you are writing into unallocated memory, with undefined results.
printf("\n Address is : %u String is : %s\n", buf, buf);
free( buf);
exit( 0 );
Instead of asking why you get different results on different platforms, you should be asking why the program doesn't crash on all platforms. :-)
You can avoid these problems with keeping track of allocating memory by using the C++ standard library instead of trying to manage low-level details yourself as in C code.
The standard string class, for example, extends itself as needed, and ensures that heap memory is freed when the string object is deleted or goes out of scope. You don't need pointers, malloc, free, or sizeof to use C++ strings.

Why keyboard and mouse right click not working in Solaris and Linux?

Hi all,
I have two problems:
1) I am working on AWT/Swing application and its working fine in window enviornment,but while running on solaris and linux mouse right-click option window not poping up.
2) Ctrl+c,Ctrl+v,Home and End keyboard key are not working in solaris and linux OS for same application.
Pls provide me some solution for these problem.
-Dinesh

Hi Nik,
Thanks for reply. I found some solution for the above problem.
For mouse right click there was problem in my source code.I have not implemented the mousePressed() method
In case of keyboard Home, End and arrow key working fine after exporting AWTUSE_TYPE4_PATCH=false; in solaris and linux
But still Ctrl-c and Ctrl-v not working.
I am using JDK1.5.0_07+Eclipse IDE 3.1

Installing 11i on Solaris and migrating 8.0.5 to new 8.1.6 database

I've installed 11i (several times) on a new Sun solaris server. I also selected it to install a fresh database. On another server we have 11.0 and 8.0.5 database. We are using a new server to install 11i and we want to move our database over. I managed to transfer all database files over to the new server and upgrade to 8.1.6 (succeeded)
How do I proceed now to get the 11i applications to use the database i've transferred over. Is this possible??? Can't find any clear documentation on how to merge this database into the applications 11i.
Thanks
null

Gina, I am attempting something similar... but it involves moving an exisiting installation from HP-UX to Solaris, so I cannot move the datafiles... If I run into a method that helps both of us, I will let you know... as of now, I am installing fresh on Solaris and going to try to run upgrade scripts on existing 10.7 and exp/imp into the new instance on 11i (Solaris).
Let me know of anything you find out that could help me, and I will do the same...
thanks

11gR2 Grid Infrastructure and 11gR2 RAC install as separate users (RH 5)

We are about to set up a few new RH 5 clusters and are trying to make a decision if we should install 11gR2 Grid Infrastructure and 11gR2 RAC as the same user (oracle) or as separate users (grid and oracle) as per Oracle documentation.
I would like to know what other people are doing and their experiences with this.
Here are some concerns that we have:
1) Does Oracle support has an 11gR2 cluster environment where grid infrastructure and oracle database are installed as separate users ? I have been to a few Oracle 11gR2 demos and they always have a simple install where everything is installed as a single user.
2) Potential permission issues that we might hit iif we use separate users, for example
- grid control agent - which user do we install it as and will it be able to access both grid and oracle files ?
- database listener will run as grid user. Is this going to cause any permission issues ?
Thanks in advance for your answers

It is all dependent on your business whether your business needs to separate between privileged user for storage administrator (ASM) or database level. It is recommended to have user separation but not mandatory.
see http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/toc.htm for the details
permission issues might happen if the configuration is not correct. for example you might see ORA-12537 when configuring the system
Hope this helps

Oracle 11gR2 64 bits and 32 bits client together??

Hello Gurus, one question for you..
We are installing FIN 9.1 over Tools 8.51 on Windows 2008 and with Oracle 11g2. Our questions is which is the best configuration?
- 11gR2 64 bits and 32 bits client (for application/ batch server)? Would this actually work?
- 11gR2 32 bits (even though it's not certified)?
I would gladly appreciate any advise/comments. Thanks.
Andy

You'll need to install Oracle 64bit (for the database - the 32bit database software won't install on a 64bit OS), and since you're on Windows, you'll also need the Oracle 32bit client (unlike previous version, there's no 32bit librairies delivered within 11gR2 64bit database software). It is fully certified and works fine.
Nicolas.

11gR2 Linux DB and 11gR1 Windows client

JNI, Solaris and Signal 11

There are a number of bugs in the database that have the following attributes:
-JNI
-Solaris
-Signal 11 exceptions.
-Long running applications.
I am experiencing something similar. I was using C threads for some call back functionality (and of course registering it them with JNI.) I was hoping that starting the threads with java would help but it didn't.
I have several questions:
-Has anyone found anything that allows them to work around this? Doesn't matter what you think it was - like a different switch on an application server. I am just curious if anyone thinks they solved it in any way.
-Does anyone have an idea what might cause it? Even an just an idle thought?
-Does anyone have a long running application, that uses JNI on Solaris and they don't experience this (obviously the JVM itself does this, but I am still curious?)
-And slightly different that the above, does anyone have a long running JNI Solaris application using C threads that doesn't have this problem?

jschell, are you still experiencing this?
You may have seen some of my posts before... I have seen many of yours. But I hadn't seen this one until now, by chance.
I am running on Solaris 8 with Java 1.3.1_03 and have a multithreaded C/C++ program that invokes the JVM and makes calls into Java via JNI. Actually, I have a few programs like this, but a particular one is set up to run as a daemon and eventually (after a couple of hours) runs into a segmentation fault (signal 11). The stack in the core file when the program fails shows that a thread started in the native code attempted "AttachCurrentThread()" and then a segfault happens way down in the JVM somewhere. However, I had an issue like this previously and I tracked it down (unexpectedly) to a memory leak in a totally unrelated portion of the native code. So I am trying to find other memory leaks in the code using tools like Rational Purify but it is tricky to get Purify and the JVM to play nicely together.
Additional info: I have all latest patches applied, not using signal handlers, and am using the "alternate" thread library in /usr/lib/lwp.
- I have another similar program on Solaris that does not seem to have this problem.
- The same program that's crashing on Solaris seems to run OK on both Windows and HP-UX.
Given the above, I am pursuing the avenue of a memory corruption in the native code as that has turned out to be the cause of numerous other problems in the past, but I am having a very hard time with this one. jschell (or anyone else), please let me know about your status and what you think.
Thanks -
Chris
