Some notes
I found this document in Sun Blueprint. It is created by Glen Brunette, one of Sun guys that i admired.
There's 2 things in the document that did not point out, one of them is giving permission to /var/audit/* files, and the other one is stopping cryptoadm by non-root user bring the cryptosvc to maintenance state when try to bring up.
First 'problem' details:
Assuming i am user weehing, and i was assigned "Audit Review" profile. Now i would like to audit user oracle activity, this is the same steps as illustrated in Glen's doc.
[weehing@pw250 ~]$ auditreduce -m AUE_su -r oracle | praudit -s | more
auditreduce: couldn't open:
/etc/security/audit/localhost/files/20080723041356.20080723041357.pw250: Permission denied
auditreduce: couldn't open:
/etc/security/audit/localhost/files/20080723041357.not_terminated.pw250: Permission denied
file,1970-01-01 07:30:00.000 +07:30,
file,2008-07-23 13:55:50.000 +08:00,
[weehing@pw250 ~]$ ls -l /etc/security/audit/localhost/files/*
-rw------- 1 root root 70 Jul 23 12:13 /etc/security/audit/localhost/files/20080723041356.20080723041357.pw250
-rw------- 1 root root 21080 Jul 23 13:58 /etc/security/audit/localhost/files/20080723041357.not_terminated.pw250
To allow weehing to audit oracle's activity, read permission would have to be given to weehing. This can be solved by a change in audit binary file permission, but this can be be another concern.
Second 'problem':

How to bring the cryptosvc back to online state??

Well, this is nothing much, but just some findings for reader who follows Glen's doc and might hit the same things like me.

Rcapd daemon
--------------------------------------------------------------------------------------
Please note that the rcapd daemon cannot determine which pages of memory are shared
with other processes or which are mapped multiple times within the same process. Hence,
it is not recommended that shared memory-intensive applications, like Oracle databases,
run under projects that use rcapd to limit physical memory usage.

Something about Oracle user and Solaris project
IF you primary Oracle group is not dba (say your primary group is oinstall), and you try to make project group.dba as your primary project, huhh nothing will change when you type "id -p". You still get back the project called default as your primary project. (In fact, i shouldn't use the term "primary project", as this is not accurate).
So create a project something like "user.oracle" and make it your oracle primary project, it will works.
See below:
[root@pw450 /]$ su - oracle
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
[oracle@pw450 ~]$ id -p
uid=200(oracle) gid=200(oinstall) projid=3(default)
[root@pw450 /]$
[root@pw450 /]$ projadd -U oracle -K "project.max-shm-memory=(priv,4g,deny)" \
> -K "project.max-sem-nsems=(priv,256,deny)" \
> -K "project.max-sem-ids=(priv,100,deny)" \
> -K "project.max-shm-ids=(priv,100,deny)" group.dba
[root@pw450 /]$
[root@pw450 /]$ su - oracle
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
[oracle@pw450 ~]$ id -p
uid=200(oracle) gid=200(oinstall) projid=3(default)
...............oppps..........it doesn't work, you are however being added to the member list of the project group.dba.
so we will create user.oracle instead.
see below:
[root@pw450 /]$ projdel group.dba
[root@pw450 /]$
[root@pw450 /]$ su - oracle
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
[oracle@pw450 ~]$ id -p
uid=200(oracle) gid=200(oinstall) projid=3(default)
[oracle@pw450 ~]$ exit
logout
[root@pw450 /]$
[root@pw450 /]$ projadd -U oracle -K "project.max-shm-memory=(priv,4g,deny)" \
> -K "project.max-sem-nsems=(priv,256,deny)" \
> -K "project.max-sem-ids=(priv,100,deny)" \
> -K "project.max-shm-ids=(priv,100,deny)" user.oracle
[root@pw450 /]$
[root@pw450 /]$ su - oracle
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
[oracle@pw450 ~]$ id -p
uid=200(oracle) gid=200(oinstall) projid=100(user.oracle)
[oracle@pw450 ~]$ cat

Bug in Tectia SSH2
Solaris 10 08/07 running multiple containers. In one of the containers Tectia SSH2 server is installed and run. The Solaris' openssh server is disabled. I found this while installing Oracle 10gR2 in the container. To install Oracle in the container, i have created a project called user.oracle (as usual) and assign the project to oracle user.
When i login to the container using zlogin, the user oracle shows that is has correct project "user.oracle" assigned. But login using f-secure ssh client shows that the project still has assigned to the default project "user.root". I have problem determining the problem in the first place as i used ssh, zlogin and telnet all at the same time and annoyed by the 'intermittent' occurrence of project that showed incorrectly to the user oracle.
At last, i noticed it, and i shutdown the Tectia ssh2 server and started the Solaris Openssh server. Yes, login as user oracle using f-secure client or putty ssh client all show correct project assigned.
See below:
Global zone hostname: pw450
Container name: dbtest
Container running solaris openssh and login using either putty or f-secure shows correct project.
Container running Tectia SSH2 server and login as oracle using either putty or f-secure shows incorrect project assigned.
Not sure this is a bug or some misconfiguration.
Kernel setup for Oracle 10g
=====================================================
#projadd -U oracle -K "project.max-shm-memory=(priv,4g,deny)" -K "project.max-sem-nsems=(priv,256,deny)" -K "project.max-sem-ids=(priv,100,deny)" -K "project.max-shm-ids=(priv,100,deny)" user.oracle

Full-sized instant volume snapshots - method 2 : using empty volume
1. find the required size for the snapshot volume.
#LEN=`vxprint -g datadg -F%len vol01`
2. find the name of the dco volume
#DCONAME=`vxprint -g datadg -F%dco_name vol01`
3. find the dco region size.
#RSZ=`vxprint -g datadg -F%regionsz $DCONAME`
4. Create a volume of the required size and redundancy
#vxassist -g datadg make snapvol01 $LEN init=active
5. To prepare the volume for snapshot operation
(to enable the fast resync using dco)
#vxsnap -g datadg prepare snapvol regionsize=$RSZ
6. create the snapshot using the empty volume.
#vxsnap -g datadg make source=vol01/snapvol=snapvol01
7. split the snapshot volume into a separate disk group
#vxdg split datadg offhostdg snapvol01
or
#vxdg -g datadg -o expand split datadg offhostdg snapvol01 snapvol02
8. deport the disk group
#vxdg deport offhostdg
9. import the disk group in remote host
(remote host)#vxdg import offhostdg
10. recover the disk group
(remote host)#vxdg -g offhostdg -sb
11. XXX Perform off-host processing XXX
fsck and mount, etc.....
12. deport the disk group
(remote host)#vxdg deport offhostdg
13. import back on the local host.
#vxdg import offhostdg
14. join the disk group
#vxdg join offhostdg datadg
15. Recover the disk group.
#vxrecover -sb
if the volume still in disabled state, then start it.
#vxvol -g datadg start vol01
16. update the snapshot volume
(refreshing the volume will sync the changed block from vol01 to
snapvol01)
#vxsnap -g datadg refresh snapvol01
or
#vxsnap -g datadg refresh snapvol01 source=vol01
17. If full resync of the volume is needed, then a reattach is required.
#vxsnap -g datadg reattach snapvol01 source=vol01
18. remove the snapshot volume if not required anymore.
#vxedit -g datadg -rf rm snapvol01
Full-Sized Instant Volume Snapshots - method 1: addmir to have 1 plex to attach to the volume.

Linux VIO Considerations
1. For AIX 5L V5.3 VIO clients, only the APV VIOS is supported by IBM.
2. Linux VIO clients may use the APV VIOS or the Linux VIO server.
So it seems to be that having Linux VIO client is a better choice.
But do i want to run linux on such expensive IBM hardware??!
I can achieve better performance, availability and serviceability by running linux on x64/x86 server.
Conclusion is Linux VIO client / server is only meant for rich and affordable customers.

Veritas problems and solutions.
We have a machine running Solaris and VxVM, attached to a Clarion box. The SAN link was down, and Storage guy managed to bring the link back after a while. We had a situation where:
1. OS detects all the SAN disks.
2. VxVM had not able to recognize back the original disks, though the device paths are the same.
3. All fs mounted on those disks have IO error. Though a format read test is passed.
4. It seems that this is purely a VxVM problem now.

Solution 1:
Part 1:
1. vxdctl enable
2. vxdisk list <--- you will see plenty of failed disk message because of broken SAN link.
3. /etc/vx/bin/vxreattach
4. vxdisk list
Part 2:
1. vxmend -g dg01 -o force off home-01
2. vxmend -g dg01 on home-01
3. vxmend -g dg01 fix clean home-01
4. vxvol -g dg01 start home
5. fsck -F vxfs /dev/vx/rdsk/dg01/home
6. mount -F vxfs /dev/vx/dsk/dg01/home /export/home
You only need to fix on 1 plex, the clean plex will resync the other plex which has problem.

Again, you only need to fix 1 plex. It will automatically resync the other plex.

Smart Tunnel and etc
Explanation
The SA wants to do a fsck but afraid the it might cause unpredictable error on the disks. (Well,
i dont think this is really necessary, but the user requested for it)
This machine has the boot disks encapsulated and mirrored. First we want to know the mirrored disk's plex. The mirrored disk is c2t1d0. You can see the purpose is to break mirror and boot up onmirrored disk to perform a fsck on mirrored disk. When it's done, boot up from root disk and
reattach the mirror.

You figure out first what's this..
# vxprint -thg rootdg | grep pl | grep 02
pl export-02 export ENABLED ACTIVE 8389656 CONCAT - RW
pl local-02 local ENABLED ACTIVE 8389656 CONCAT - RW
pl pstore-02 pstore ENABLED ACTIVE 205119 CONCAT - RW
pl rootdisk1vol-02 rootdisk1vol ENABLED ACTIVE 4194828 CONCAT - RW
pl rootvol-02 rootvol ENABLED ACTIVE 29360907 CONCAT - RW
pl var-02 var ENABLED ACTIVE 12584484 CONCAT - RW
- Remove volume pstore.
# vxassist –g rootdg remove pstore
- Set up system boot information on mirror disk
# /etc/vx/bin/vxbootsetup rootmirr
- Break rootmirror (c2t1d0)
# vxplex –g rootdg dis rootvol-02
# vxplex –g rootdg dis rootdisk1vol-02
- FSCK mirror disk (c2t1d0).
# fsck –F ufs /dev/rdsk/c2t1d0s0
- Mount root file system in mirror disk
# mount /dev/dsk/c2t1d0s0 /mnt
- Change /etc/system in mirror disk
# cd /mnt/etc
# cp system system.ddmmyy
# cp system.rfc263171 system
- Change /etc/vfstab in mirror disk.
# cd /mnt/etc
# cp vfstab vfstab.ddmmyy
# cp vfstab.rfc263171 vfstab
The entries from / and /swap will be changed as shown:
/dev/dsk/c2t1d0s1 - - swap - no -
/dev/dsk/c2t1d0s0 /dev/dsk/c2t1d0s0 / ufs 1 no logging
- Un-mount file system.
# cd /
# umount /mnt
- Shutdown system. Reboot system,
# init 0
ok boot vx-rootmirror -sw
Enter root password to enter maintenance mode
Perform FSCK on /
# fsck –F ufs /dev/rdsk/c2t0d0s0
When done, bring down system
# init 0
- Reboot system with vx-rootdisk,
ok boot vx-rootdisk
IF boot is OK, go to step 11.
IF boot failed, go to step 12.
- Re-attach mirror,
# vxplex –g rootdg att rootvol rootvol-02
# vxplex –g rootdg att rootdisk1vol rootdisk1vol-02
Job done. Use “vxtask list” to check progress of synchronization.
- Boot the system off the detached mirror disk,
# init 0
ok boot vx-rootmirror –s
- Check to ensure system is booted with disk slices rather than volume devices.
# df –k /
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c2t1d0s0 14451472 4468338 9838620 32% /
- Stop all volumes in rootdg, re-attach those detached plexes,
# vxvol –g rootdg stopall
Attach detached plexes,
# vxplex –g rootdg att rootvol rootvol-02
# vxplex –g rootdg att rootdisk1vol rootdisk1vol-02
Make the newly attached plexes active,
# vxmend –g rootdg –o force off rootvol-01
# vxmend –g rootdg –o force off rootdisk1vol-01
# vxmend –g rootdg fix clean rootvol-02
# vxmend –g rootdg fix clean rootdisk1vol-02
# vxvol –g rootdg startall
- Revert /etc/system and /etc/vfstab from backup files created earlier,
# cp /etc/system.ddmmyy /etc/system
# cp /etc/vfstab.ddmmyy /etc/vfstab
- Shutdown system and reboot with mirror disk again,
# init 0
Ok boot vx-rootmirror
System should boot up using volume device, “df –k /” to verify,
# df –k /
Filesystem kbytes used avail capacity Mounted on
/dev/vx/dsk/bootdg/rootvol
14451472 4468384 9838574 32% /
- Online the disabled plexes,
# vxmend –g rootdg on rootvol-01
# vxmend –g rootdg on rootdisk1vol-01
Synchronization will starts, use “vxtask list” to check progress.

李登輝!
He must be referring to our red dot Mr. Lee. Well, he always like to compare himself with the senior Lee.
Is he any better than Senior Lee? Personally i think not!

House survey 1
CHERAS TMN Cheras Indah d/s 18x60 Nlot 3r2b fully extended RM235K (Value buy) well kept 012-2906029, 03-92003864 Alex E(3)0931 20/3/2007
Everything is ok except -- this is leasehold house, and it has balance of about 70+ years.
Free hold house is very important factor in my buying decision. Never look back.
