ODA - Oakcli commands hang when executed

[Amr Samy]

Hi Erman,

on ODA X4-2 System , The problem is that the Oakcli commands hang when executed. No errors are shown, the commands simply do not complete,
I can't stop , start , create repository or VM.
only oakcli show commands is working well.


thanks in advance

Hi,

Check oakcli log file;
Location: in ODA BASE in the relevant node where te commands hang;

/opt/oracle/oak/log/<server_name>/client/oakcli.log

Also check the oakd log files.
Location: in ODA BASE in the relevant node where te commands hang;

/opt/oracle/oak/log/<server_name>/oak

Your oakd logs are up-to-date, but  your latest oakcli log record is written at 03.07.20106.

This is your last oakcli log record;

2016-03-07 18:16:07.138: [CLSFRAME][3466339904] M2M is now powered by a doWork() thread.

Did you send me up-to-date logs?

[Amr Samy]

yes, I send the up-to-date logs.

but I used oakcli commands after this date !

[ErmanArslansOracleBlog]

send me an strace output of your failing oakcli command. like;

strace oakcli start vm blablaba

[Amr Samy]

Link of output

and hanging after last line .

[ErmanArslansOracleBlog]

There are some important records in strace output.

"ERESTARTSYS" and "--- SIGWINCH (Window changed)"

1) Retry this command using putty or VNV Viewer or SSH Secure Shell Client (dont resize your terminal size during the execution of oakcli), this may effect the execution. Look it effects to Data Guard command-line interface ->Abnormal Termination Of Dgmgrl When Shell Window In Resized (Doc ID 1909799.1)
2) Reboot ODA BASE nodes and retry, as this may be a temporary situation caused by OS

Send me the updates after those actions.
This can be a bug in OS or oakcli itself.
If the above actions wont fix the problem, send me the log file /opt/oracle/oak/log/ <server_name>/oakvmclient

Thank youuu soooo much , the issue is solved

but there is an issue in the repository , and I cannot start VM

[root@cairo3-oda0 ~]# oakcli show repo prodrepo -node 0

[ErmanArslansOracleBlog]

send me the problematic command and its output.

[Amr Samy]

[root@cairo3-oda0 ~]# oakcli start vm testvm

I start VMs normally in another repository , but in this repository I cannot.

[ErmanArslansOracleBlog]

Send me the related log files, like you did in your previous problem.

Kindly can you specify locations of logs that can help to solve the problem ?

thanks

[ErmanArslansOracleBlog]

Location: in ODA BASE in the relevant node where the commands failed 

/opt/oracle/oak/log/<server_name>/client/oakcli.log 

Also check the oakd log files.

Hi,

I have the same problem. After importing the dbvm into the repository i'm not able to start the vm with

oakcli start vm dbvm

It just says :

Start VM : dbvm on Node Number : 0 failed.

There is a bug  bug: 21101080 to solve this you should edit the vm.cfg and change :

xvdb:/OVS/Repositories/appsrepo/.ACFS/snaps/dbvm/VirtualMachines/dbvm/cdrom,r
 to:
 xvdb:cdrom,r

But when you state :  oakcli show vm dbvm  this doesn't show up, not even after restarting oak or oda_base or even a physical reboot of the both nodes of the cluster via the ILOM.

Any idea's ?

Hi,

1)Did you take corrective action for bug : 21101080

2)Send me the output of "oakcli show vm dbvm" and "oakcli show vm"

[rkrieg]

Hi,

We changed the vm.cfg to solve the bug. Here's the output of the commands :

I could not understand...
Please explain what your problem is...

you sent me the outputs. So, as I see, oakcli creates proper outputs. What is your problem?
