ORACLE OS WATCHER
What is oracle OS watcher?
Oracle OS watcher is collects and stores as archives operating system and network metrics that you can use to diagnose performance issues. OSWbb operates as a set of background processes on the server and gathers a data on a regular basis, invoking such UNIX utilities such as vmstat, netstat, iostat, top, etc.
By using of OSWbba analyzer to provide information on system slowdowns, system hangs and other performance problems, and also to graph data collected from iostat, netstat, and vmstat.
In General, OSWbb requires the java version of 1.4.2 or higher version in our environment.
OSwbb is particularly useful for RAC environment and also oracle grid infrastructure.
Where to download the OS watcher and execute it?
Step1:
We can download the Oracle OS watcher software from my oracle support website itself.
https://support.oracle.com/epmos/main/downloadattachmentprocessor?attachid=301137.1:OSW_file.
Step 2:
Then, move or copy this file to directory where we need to run the oswbb software and un-tar the file.

[root@training dbhome_1]#Step 3:
After above step, we have to install ksh (koron shell) using yum install.
[root@training dbhome_1]# yum install kshLoaded plugins: langpacks, ulninfo
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

Package ksh-20120801-142.0.1.el7.x86_64 already installed and latest version
Nothing to do
Step 4:
Then, when we complete an un-tar(tar –xvf owsbb.tar) function, it will create the directory name of “oswbb”. In that directory has a shell script to execute the oswbb and .jar files are located there.

Step 5:
To stop the oswbb we should execute it stopOSWbb.sh.
[root@training oswbb]# sh stopOSWbb.sh [root@training oswbb]#
WHERE WE CAN GET THE ALL OUTPUT and HOW TO VIEW THAT
Step 6:
When the execution of os watcher it will create the directory called archive, we can get the all outputs in that archive directory, which we want to check the data, just navigate to that directory and view the file by using more command, because it is bigfile, so using of more command is best.
For eg: navigation to output:
$ cd $ORACLE_HOME/oswbb/archive
TO VIEW and ANALYZE THE OSWATCER REPORT.
For eg:
$ more file_name.dat
OSWbb collects data in the following directories under the oswbb/archive directory:
| DIRECTORY | DESCRIPTION |
| oswiostat | Contains output from the iostat utility. |
| oswmeminfo | Contains a listing of the contents of /proc/meminfo. |
| oswmpstat | Contains output from the mpstat utility. |
| oswnetstat | Contains output from the netstat utility. |
| oswprvtnet | If you have enable private network tracing for RAC, contains information about the status of the private networks. |
| oswps | Contains output from the ps utility. |
| oswslabinfo | Contains a listing of the contents of /proc/slabinfo. |
| oswtop | Contains output from the top utility. |
| oswvmstat | Contains output from the vmstat utility. |
