When we raise a SR to oracle, they will require Diagnostic collection of log files for troubleshooting for that specific timelines when the error has occurred.
To collect diag we need to run the below procedure on all the nodes. So oracle recommends to use TFA. This note covers only diag collection on each node.
Below note is for 11.2 onwards.
**************************************** Step By Step Procedure ******************************************************
#########################################
# 1) Info before start the diag collection
#########################################
User : root (As this collect OS diag logs, its recommended to run as root user else we will be able to capture all the info's)
ORACLE_HOME : ASM Grid Home
Script Used : diagcollection.sh (Inbuilt Script comes as a part of Grid software Installation)
Temporary Directory : /tmp/srini (To Store the generated files.)
Time Stamp when the
Error has occurred : 08/16/201614:20:00 ( Format is MM/DD/YYYY24HH:MM:SS)
Duration until you
want to capture : 2 Hours (Capture 2 hours from the time of error occurred)
=====================================================================================================================
#########################################
# 2) Run the Diag Collection
#########################################
Below Command need to run on all the nodes of the cluster as root user.
cd /tmp/srini
/ofa/u001/app/oracle/grid/11.2.0.4/bin/diagcollection.sh --chmos --incidenttime 08/16/201614:20:00 --incidentduration 02:00
Where,
GRID_HOME=/ofa/u001/app/oracle/grid/11.2.0.4
=====================================================================================================================
#########################################
# 3) Generated Files
#########################################
[root@SIDHOST srini]# ls -ltr
total 29148
-rw-r----- 1 root root 290141 Aug 16 16:41 sysconfig_SIDHOST_20160816_1639.txt
-rw-r----- 1 root root 29514879 Aug 16 16:41 osData_SIDHOST_20160816_1639.tar.gz
[root@SIDHOST srini]#
=====================================================================================================================
#########################################
# 4) Change OWnership
#########################################
As the files are generated as root user, i need it to change as oracle to FTP and upload to ORacle support.
chmod -R oracle:dba /tmp/srini/
[root@SIDHOST srini]# ls -ltr
total 29148
-rw-r----- 1 oracle dba 290141 Aug 16 16:41 sysconfig_SIDHOST_20160816_1639.txt
-rw-r----- 1 oracle dba 29514879 Aug 16 16:41 osData_SIDHOST_20160816_1639.tar.gz
[root@SIDHOST srini]#
