Exadata manual ILOM Update Why?

ILOM

After the last Patching activity we made a quality check

We were really surprised that the ILOM and BIOS on the DB Nodes was not updated

Normally this was implicit done during the Patch implementation

How can you fix this?

First check the actual firmware version 


dcli -l root -g all_group ipmitool sunoem version
s8db1: Version: 3.0.16.20.e r89119
s8db2: Version: 3.0.16.20.e r89119

Second check the Exadata Machine hardware profile 

/opt/oracle.cellos/CheckHWnFWProfile -d
[root@s8db1 cellbits]# /opt/oracle.cellos/CheckHWnFWProfile
[WARNING] The hardware and firmware does not match with the profile. See details below

<Check_Result Server_Model="Sun_Fire_X4800_M2">
<Check_Result_for_BIOS>
<BIOS>
<BIOSVersion>
<Required VALUE="15020800"/>
<Found VALUE="15020500"/>
</BIOSVersion>
</BIOS>
</Check_Result_for_BIOS>
<Check_Result_for_ILOM>
<ILOM>
<ILOMVersion>
<Required VALUE="3.0.16.34 r101426</strong>"/>
<Found VALUE="3.0.16.20.e r89119</strong>"/>
</ILOMVersion>
</ILOM>
</Check_Result_for_ILOM>
</Check_Result>

[WARNING] The hardware and firmware does not match with the profile. See details above

Third fix the old firmware by starting an manual update

 

Step 1 Check the file dbfw.tbz in directory /opt/oracle.cellos/iso/cellbits to observe that the required 
       ILOM firmware package file is included
# cd /opt/oracle.cellos/iso/cellbits
tar tvf dbfw.tbz| grep -i ILOM
-rw------- root/root 22859968 2015-07-26 02:25 ActualFirmwareFiles/ILOM-3_0_16_34_r101426-Sun_Fire_X4800M2.pkg

Step 2 Update the ILOM version manually
# /opt/oracle.cellos/CheckHWnFWProfile -U /opt/oracle.cellos/iso/cellbits

Step 3 Check for updated ILOM version
# /opt/oracle.cellos/CheckHWnFWProfile -d

Please take care not only the ILOM Service processor will reboot

The whole DB Node is restarted

So do the Update in a rolling manner 

 


			

Exadata EM 12c agent error after Upgrade to OL6 „unable to create new native thread“

cluster_patch

Recently we did some patching activity on our Exadata machines.

One part is the Upgrade of the DB Nodes which includes the upgrade to Oracle Linux 6.

This works fine but afterwards we had a problem starting our the Cloud Control agent.

We saw the following error message: „unable to create new native thread“

[oragrid@db1 ~]$ emctl start agent

Oracle Enterprise Manager Cloud Control 12c Release 5

Copyright (c) 1996, 2015 Oracle Corporation. All rights reserved.

Starting agent .................................................................... started but not ready.

[oragrid@db1 ~]$ emctl status agent

Oracle Enterprise Manager Cloud Control 12c Release 5

---------------------------------------------------------------

unable to create new native thread

[oragrid@db1 ~]$ emctl status agent

Oracle Enterprise Manager Cloud Control 12c Release 5

Copyright (c) 1996, 2015 Oracle Corporation. All rights reserved.

---------------------------------------------------------------

The problem will be fixed by the following MOS Note and action

EM 12c : Agent Restarts Due To Out Of Memory Exception “ unable to create new native thread“ Out Of System Resources (Doc ID 1499576.1)

For OEL6.x /RHEL 6.x
vi /etc/security/limits.d/90-nproc.conf

* soft nproc 1024

root soft nproc unlimited

Change TO

* soft nproc 65536

Restart the agent:

$<AGENT_INST>/bin/emctl stop agent

$<AGENT_INST>/bin/emctl start agent

 After restarting the agent everything works fine.
