How to find the HPUX is PA-RISC or Itanium

Itanium will show ia64

systemname:/# uname -a
HP-UX sys-abc B.11.23 U ia64 3875925350 unlimited-user license

PA-RISC will not but instead show the series (9000/800)

systemname:/# uname -a
HP-UX sys-abc B.11.23 U 9000/800 139872607 unlimited-user license

Solution:
Unfortuantely that probably means you reached the maximum number of PV allowed for this Volume Group.

do a
#vgdisplay -v indrtest|more

and check that your Max PV is higher than the Cur PV. If they are equal (which is what I think is happening right now), that means you cannot add any more disks into that VG.

You either have to create a new VG, or re-create this current VG with option -p to have more disks than the actual value.
Cooperation is doing with a smile what you have to do anyhow.

VCS WARNING V-16-1-10484 Group dependency is violated

root@hostname2# hagrp -switch depkms_sg -to hostname2 

VCS WARNING V-16-1-10484 Group dependency is violated if group depkms_sg goes offline on system hostname1

Cause:

In an online Gloabal Dependency, a child service group must be online on a system in the cluster before the parent service group can come online

The child service group cannot be taken offline while the parent service group is online, however the parent service group can be taken offline while the child service group is online

Solution:

1) Determine the child and parent service groups

root@hostname1# hagrp -dep depkms_sg       

#Parent      Child      Relationship

unica_sg     depkms_sg  online global firm

2) Offline the parent service group, switch the child service group to another system and thenonline the parent service group again.

How To Start, Stop and Restart Oracle Listener

How To Start, Stop and Restart Oracle Listener

1. Display Oracle Listener Status

Before starting, stopping or restarting make sure to execute lsnrctl status command to check the oracle listener status as shown below. Apart from letting us know whether the listener is up or down, you can also find the following valuable information from the lsnrctl status command output.

Listner Start Date and Time.
Uptime of listner – How long the listener has been up and running.
Listener Parameter File – Location of the listener.ora file. Typically located under $ORACLE_HOME/network/admin
Listener Log File – Location of the listener log file. i.e log.xml

If the Oracle listener is not running, you’ll get the following message.

2. Start Oracle Listener

If the Oracle listener is not running, start the listener as shown below. This will start all the listeners. If you want to start a specific listener, specify the listener name next to start. i.e lsnrctl start [listener-name]


#  lsnrctl start

3. Stop Oracle Listener

If the Oracle listener is running, stop the listener as shown below. This will stop all the listeners. If you want to stop a specific listener, specify the listener name next to stop. i.e lsnrctl stop [listener-name]


$ lsnrctl stop
LSNRCTL for Linux: Version 11.1.0.6.0 - Production on 04-APR-2009 16:27:37

The command completed successfully

4. Restart Oracle Listener

To restart the listener use lsnrctl reload as shown below instead of lsnrctl stop and lsnrctl start. realod will read the listener.ora file for new setting without stop and start of the Oracle listener.
