create IPS repository in Solaris 11.2

I discussed before how to create package repository on Linux here, the same could be happened on Solaris 11.2 when you install Database any version mandatory packages should be installed to make it easy repository helps you a lot and will be available any time you need, and Image packaging system(IPS) repository is one of the important things in Solaris 11 onwards.

You need to download the following files & upload them to the server :-

Once the file is ready upload them to the server under one file called Repo for example. it should looks like the below :-

#ls -lrt
total 14373947
-rwx——   1 root     root     1771800121 Aug  9 08:24 sol-11_2-repo-1of4.zip
-rwx——   1 root     root     1889867782 Aug  9 11:20 sol-11_2-repo-2of4.zip
-rwx——   1 root     root     1902167161 Aug  9 22:34 sol-11_2-repo-3of4.zip
-rwx——   1 root     root     1790358735 Aug 10 00:16 sol-11_2-repo-4of4.zip
-rwx——   1 root     root        5594 Aug 10 20:16 install-repo.ksh
-rwx——   1 root     root         228 Aug 10 20:17 sol-11_2-repo-md5sums.txt
drwxr-xr-x   2 root     root           2 Aug 10 20:40 repo

#pkg publisher
PUBLISHER TYPE STATUS URI
solaris origin online http://pkg.oracle.com/solaris/release/

 as you see from the above output package publisher still working under oracle Link. Let’s Start Working, Set the executable bit for install-repo.ksh and execute like below.

#./install-repo.ksh -d /export/oracle/repo/ -v -c
Comparing checksums of downloaded files…done. Checksums match.
Uncompressing sol-11_2-repo-1of4.zip…done.
Uncompressing sol-11_2-repo-2of4.zip…done.
Uncompressing sol-11_2-repo-3of4.zip…done.
Uncompressing sol-11_2-repo-4of4.zip…done.
Repository can be found in /export/oracle/repo/.
Initiating repository verification.

Again Check the current publisher.

#pkg publisher
PUBLISHER                   TYPE     STATUS P LOCATION
solaris                     origin   online F http://pkg.oracle.com/solaris/release/

configure the new publisher, Path should be the same.

#pkg set-publisher -G ‘*’ -M ‘*’ -g file:///export/oracle/repo solaris

#pkg publisher
UBLISHER                   TYPE     STATUS P LOCATION
solaris                     origin   online F file:///export/oracle/repo

Configure the repository service to point to the new location by run the following command :-

# svccfg -s application/pkg/server setprop pkg/inst_root=/export/oracle/repo 


Check

# svcprop -p pkg/inst_root application/pkg/server

Reload the Services Just to confirm :-

# svcadm refresh application/pkg/server

Use "sudo" Command without password Prompt

Sometimes you need to run Linux command without password prompt using sudo command.

to learn more about this command read the link here.

For Example i need to run the following command without password prompt, However there are three sudo commands I want to run without entering password:

  • sudo reboot
  • sudo shutdown -r now
  • sudo shutdown -P now
to do this follow the below steps :-
  • edit the following /etc/sudoers file.
  • you find the following lines depend on the username and hostname for the server.

user host = (root) NOPASSWD: /sbin/shutdown
user host = (root) NOPASSWD: /sbin/reboot

This will allow the user user to run the desired commands on host without entering a password. All other sudoed commands will still require a password.

Notes:

  • Always use the command visudo to edit the sudoers file to make sure you do not lock yourself out of the system for example 

sudo visudo -f /etc/sudoers.d/shutdown

  • Using /etc/sudoers.d instead of modifying /etc/sudoers, you could add the two lines to a new file in /etc/sudoers.d for example  /etc/sudoers.d/shutdown.
  • If you did not use visudo to edit your files and then accidentally messed up /etc/sudoers or messed up a file in /etc/sudoers.d then you will be locked out of sudo.to fix it use command pkexec.

My Days As an Oracle ACED : BGOUG

12 – 14 June save the date because it’s Bulgarian Oracle User group Events, this is my first time in Bulgaria and my first time as an oracle ACE director in any events :).

My Trip Planned to be from Jordan to Bulgaria – Sofia  and as usual i need to stop in one of world airport to reach my destinations first which i really hate because it’s wasting of time and tiring me.
my stop was in Frankfurt airport and to be there i had to spent 5-6 hours in the plane to reach there and then wait another 5 hours in the airport and reach Sofia 3 hours in the plane. but lucky me the plane is delayed in Jordan and i waited for 2 hours only :).
I reach Sofia but i was really exhaust and tired from traveling because my trip started early morning and it’s took us 2 hours to reach the hotel from the airport but even with this i have to thanks one of the best organizer i ever seen Milena Gerova She organized everything very well the hotels, the taxi, the appreciation events & sessions.
I had 2 presentation there about Fusion middleware and like usual i organized RAC ATTACK On Saturday, The audience was really amazing and asking very good questions. 
I had so much fun in Bulgaria and one of the best events i attended, simply it’s really Green every where you look it’s green, and I learned some Bulgarian dance  because i knew everyone in Bulgaria should dance 🙂 Even Tom Kyte was dancing,Svetoslav and Heli as well so why not ? 
It’s really nice to meet old friends and meeting new one  🙂

OID is Down For Ambiguous Reasons

Today one of the customer called complaining about accessing to the system and how its not working ? Since everything is configured as single sign on (SSO) first thing to check was OID or oracle internet Directory.

The logs indicate to the below error :-

[2015-05-01T07:00:18+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [oidmon]: Unable to connect to database,
will retry again after 10 sec

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: Connecting to database, connect string is oiddb

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [gsdsiConnect] ORA-12514, ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.

from the above error the OID is unable to connect to database server i checked database and listener everything is up without any issue and all the other application working without any issues.

after investigation I checked the sqlnet.ora and add the following :-

SQLNET.AUTHENTICATION_SERVICES= (NONE)
NAMES.DIRECTORY_PATH= (TNSNAMES)

Restart the services and everything is working.

maybe this solution will not lead or help in so many cases i am working to know why this will effect on OID since it’s was working without any issues for 1 year

Thanks
Osama
