This article mainly shows you "how to use Oracle OS Watcher tools", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to use Oracle OS Watcher tools" this article.

1. OS Watcher Black Box installation configuration (oswbb)

1. Download the tar package of oswbb, decompress it and authorize:

Tar xvf oswbb.tar

Chmod 744 *

two。 Uninstall:

To uninstall OSWatcher, issue the following command in the oswbb directory:

Rm-rf oswbb

3. Set up OSWbb

When the OSWbb installation is complete, you can use the start and stop scripts, which create archived subdirectories the first time OSWbb is used. These archive directories contain seven subdirectories, one for each subdirectory to collect data. These seven directories correspond to: top, vmstat, iostat, mpstat, netstat, ps and an optional traceprivate network.

To start private network, you must first create an executable file for private.net in the oswbb directory. The contents of this file can be used to verify the traceroute command of RAC private network

Set up communication check between private networks:

A) enter the decompressed directory and copy Exampleprivate.net as private.net to the same directory.

b)。 Find your corresponding system platform in private.net, and replace the following private_nodename1. Private_nodename2 is the specific private network IP or host name.

Traceroute-r-F private_nodename1

Traceroute-r-F private_nodename2

c)。 Delete the rest of the platform in private.net.

d)。 Never delete the following: rm locks/lock.file

4. Start / stop oswbb Starting / Stopping oswbb

Start oswbb:Starting oswbb

To start the oswbb utility execute the startOSWbb.sh shell script from the directory where oswbb was installed. This script has 2 arguments which control the frequency that data is collected and the number of hour's worth of data to archive.

ARG1 = snapshot interval in seconds.

ARG2 = the number of hours of archive data to store.

ARG3 = (optional) the name of a compress utility to compress each file automatically after it is created.

ARG4 = (optional) an alternate (non default) location to store the archive directory.

If you do not enter any arguments the script runs with default values of 30 and 48 meaning collect data every 30 seconds and store the last 48 hours of data in archive files.

-if these two parameters are not specified at startup, the default is to collect them every 30 seconds, and the archived data will be retained for 48 hours.

Example 1: This would start the tool and collect data at default 30 second intervals and log the last 48 hours of data to archive files.

This will launch the tool and collect data at the default interval of 30 seconds, and record the last 48 hours of data to the archive file

. / startOSWbb.sh

Example 2: This would start the tool and collect data at 60 second intervals and log the last 10 hours of data to archive files and automatically compress the files.

Example 2: this launches the tool and collects data at 60-second intervals and records the last 10 hours of data to archive and automatically compress the file.

. / startOSWbb.sh 60 10 gzip

Example 3: This would start the tool and collect data at 60 second intervals and log the last 10 hours of data to archive files, compress the files and set the archive directory to a non-default location.

Example 3: this starts the tool and collects data at 60-second intervals, records the last 10 hours of data to archive the file, compresses the file, and sets the archive directory to a non-default location

. / startOSWbb.sh 60 10 gzip / u02/tools/oswbb/archive

Example 4: This would start the tool and collect data at 60 second intervals and log the last 48 hours of data to archive files, NOT compress the files and set the archive directory to a non-default location.

Example 4: this launches the tool and collects data at 60-second intervals, records the last 48 hours of data to an archive file instead of compressing the file, and sets the archive directory to a non-default location.

. / startOSWbb.sh 60 48 NONE / u02/tools/oswbb/archive

Example 5: This would start the tool, put the process in the background, enable to the tool to continue running after the session has been terminated, collect data at 60 second intervals, and log the last 10 hours of data to archive files.

Example 5: this starts the tool, puts the process in the background, keeps the tool running after the session terminates, collects data at 60-second intervals, and records the last 10 hours of data to an archive file

Nohup. / startOSWbb.sh 60 10 &

Stop oswbb:Stopping oswbb

To stop the oswbb utility execute the stopOSWbb.sh command from the directory where oswbb was installed. This terminates all the processes associated with the tool.

Example:

. / stopOSWbb.sh

II. OS Watcher Black Box Analyzer installation and configuration (oswbba)

MOS:OS Watcher Black Box Analyzer User Guide [ID 461053.1]

2.1 java 1.4.2 or above must be installed before starting the OSWbba tool. Of course, if you have installed Oracle, there is also java in the oracle installation directory.

[root@dbrac1 ~] # su-oracle

[oracle@dbrac1] $java-version

Java version "1.6.020"

OpenJDK RuntimeEnvironment (IcedTea6 1.9.7) (rhel-1.39.1.9.7.el6-x86_64)

OpenJDK 64-BitServer VM (build 19.0-b09, mixed mode)

The java I installed here is version 1.6.

If you use Oracle's Java, you need to modify the environment variable to add the path of Java to the Path, such as:

PATH=$ORACLE_HOME/jdk/bin:$PATH

2.2 start oswbba

Note that displaying the picture here requires the use of X windows or xmanger graphics tools, so we will execute it in the graphics window:

Once the correct version of java has been verified, you can start oswbba. Oswbba requires an input directory to run. To specify the input directory you must use the-I option. The input directory is the fully qualified path name of an archive directory location containing the oswbb logs. The archive directory must contain the respective subdirectories--oswvmstat, oswiostat, oswps, oswtop, oswnetstat, etc. If you are running Linux or HP-UX, then additional directories are also created. It is important to note the program requires an archive directory name not an individual log directory name or individual filename.

Once the correct version of java has been verified, you can start oswbba. Oswbba requires an input directory to run. To specify the input directory, you must use the-I option. The input directory is the standard pathname of the location of the archive directory that contains the oswbb logs. The archive directory must contain the corresponding subdirectory-oswvmstat,oswiostat,oswps,oswtop,oswnetstat, etc. If you are running Linux or HP-UX, additional directories will be created. It is important to note that the program needs an archive directory name, not a separate log directory name or personal file name

The command is as follows:

Note that X windows is needed to display the picture here, so we need to execute it in the graphics window: xhost +, in the root user interface of the virtual machine terminal.

[root@dbrac1] # xhost +

Access control disabled, clients canconnect from any host

[root@dbrac1 ~] # su-oracle

[oracle@dbrac1 oswbb] $pwd

/ home/oracle/oswbb/oswbb

[oracle@dbrac1 oswbb] $

[oracle@dbrac1 oswbb] $ls oswbba.jar

Oswbba.jar

[oracle@dbrac1 oswbb] $

[oracle@dbrac1 oswbb] $java-jar oswbba.jar-I / home/oracle/oswbb/oswbb/archive

2.2 Java Heap Errors on Startup: Java heap error occurred at startup

Oswbba parses all the archive files in memory prior to generating graphs or performing an analysis. If you have a large amount of files to parse you may need to allocate more memory in the java heap. If you experience any error messages regarding out of memory such as java.lang.OutOfMemoryError, you may have to increase the size of the java heap. To increase the size of the java heap use the-Xmx flag.

T By default OSWbba parses all the OSWbb log files contained in the input directory and the default graphs are based on the entire time span of all the logs. By default, OSWbb keeps the last 48 hours of logs in the archive. This means the default graph will graph all 48 hours of data. This option allows the user to specify a different subset of times within the entire collection. An example would be only to graph a 2 hour period out of the entire 48 hour collection.

By default, OSWbba parses all OSWbb log files contained in the input directory, and the default drawing is based on the entire time span of all logs. By default, OSWbb keeps the last 48 hours of logs in the archive. This means that the default graph will draw all 48 hours of data. This option allows the user to specify a different subset of times throughout the collection. One example is just to draw 2 hours of the entire 48-hour collection.

B This option resets the graphing timescale back to the time encompassing the entire log collection. Please note this resets the time for graphs but does not reset the time for analysis.

-S This option used with other options to identify only a subset of the data in the oswbb directory will be used for analysis.

This option is used in conjunction with other options to identify only a portion of the data in the oswbb directory and will be used for analysis

-L User specified location of an existing directory to place any gif files or data files (xls files) generated by oswbba. This overrides the oswbba default location. This directory must pre-exist!

An existing directory location specified by the user to place any gif files or data files (xls files) generated by oswbba. This overrides the default location of oswbba. This directory must exist in advance!

-A Same as option An above. This option analyzes the files in the archive directory and produces a report in the analysis directory. If you do not specify an analysis directory, then the files will be placed in a system generated directory name under the analysis directory. If you do not want to put the optional name make sure this is the last option on the command line.

Same as option An above. This option analyzes the files in the archive directory and generates a report in the analysis directory. If you do not specify an analysis directory, the file is placed in the system-generated directory name under the analysis directory. If you don't want to put an optional name, make sure this is the last option on the command line

-D Same as option D above. This option generates a dashboard (responsive web page). The dashboard integrates the analyzer text base report (option A) with a menu driven interface that quickly helps identifies critical issues and provides guidance on what to look for. Selecting this option will first also force the analysis (- A) to happen. If you do not specify an analysis directory, then the files will be placed in a system generated directory name under the analysis directory. If you do not want to put the optional name make sure this is the last option on the command line

Same as option D above. This option generates a dashboard (responsive web page). The dashboard integrates the analyzer text-based report (option A) with a menu-driven interface to quickly identify key issues and provide guidance on finding content. Select this option to force the analysis (- A) first. If you do not specify an analysis directory, the file is placed in the system-generated directory name under the analysis directory.

Use with the analysis option to specify the first file located in the oswvmstat directory for analysis

-STOP Used with the analysis option to specify the last file located in the oswvmstat directory to analyze.

Use with the analysis option to specify the last file in the oswvmstat directory for analysis

-B Same as option T from the menu. The begin time will allow the user to select a begin time from within the archive of files to graph. This overrides the default start time which is the earliest time entry in the archive directory. The format of the start time is Mon DD HH:MM:SS YYYY. (Example: Jul 25 11:58:01 2007) An invalid begin time will result in using a default value of the first timestamp in your archive.

Same as option T in the menu. The start time will allow you to select the start time to the drawing from the file archive. This overrides the default start time of the earliest entry in the archive directory. The format of the start time is Mon DD HH:MM:SS YYYY. (for example, July 25, 2007, 115801). An invalid start time will cause the default value of the first timestamp to be used in your archive

-E Same as option T from the menu. The end time will allow the user to select an end time from within the archive of files to graph. This overrides the default end time which is the latest time entry in the archive directory. The format of the end time is Mon DD HH:MM:SS YYYY. (Example: Jul 25 11:58:01 2007) .An invalid end time will result in using a default value of the last timestamp in your archive

Same as option T in the menu. The end time allows you to select the end time to the drawing from the file archive. This overrides the default end time of the last entry in the archive directory. The format of the end time is Monday night: MM:SS year. (for example, July 25, 115801 2007). An invalid end time will cause your archive to use the default value of the last timestamp

2.4.3 Specifying the Begin/End Time of an Analysis (Recommended Method) specifies the start / end time of the analysis (recommended method)

Example:

Java-jar oswbba.jar-I archive-b Jan 9 13:15:00 2013-e Jan 19 13:30:00 2013-A

2.4.4 Limiting the Analysis to a Subset of Files in Your Archive (Old method) restricts analysis to a subset of files in the archive (old method)

Example:

Java-jar oswbba.jar-I archive-START coesrv40.us.oracle.com_vmstat_13.01.09.1300.dat-STOP coesrv40.us.oracle.com_vmstat_13.01.09.2000.dat-s

2.4.5 Ignoring Specific Directories From Analysis ignores specific directories from the analysis

Example:

Java-jar oswbba.jar-I archive-NO_NETSTAT-NO_IOSTAT

The options are as follows:

-NO_IOSTAT Ignores files in the oswiostat directory from analysis.

-NO_TOP Ignores files in the oswtop directory from analysis.

-NO_PS Ignores files in the oswps directory from analysis.

-NO_NETSTAT Ignores files in the oswnetstat directory from analysis.

-NO_LINUX Ignores files in the oswmeminfo directory from analysis.

-MEM_ALL Analyzes virtual and resident memory allocations for all processes. This is very resource intensive.

2.4.6 Generating a Dashboard generates a dashboard

The steps are as follows:

1. Select option (D) from them menu. This generates the dashboard

2. Cd to the analysis directory

3. Locate the analysis directory generated in step 1

4. Cd into the specific analysis directory

5. Inside the specific analysis directory there will be

A. Single analysis.txt file

B. Directory named dashboard

6. Cd into the dashboard directory

7. Inside the dashboard directory there will be

A. Index.html (This is the dashboard). Open this file with a browser

B. Css directory containing cascading style sheets used by the dashboard

C. Fonts directory containing fonts used by the dashboard

D. Generated_files directory containing gifs that were generated and used by the dashboard

E. Images directory containing misc images used by the dashboard

F. Js directory containing javascript used by the dashboard

3. Configure oswbb self-boot

The aim is to restart the host so that oswbb can start working again to collect information.

Method 1: configure crontab

0 home/oracle/dba/check_oswbb.sh 5 10 15 15 20 25 30 35 40 45 50 55 * / home/oracle/dba/check_oswbb.sh > / dev/null 2 > & 1
