    Hi


    Is it possible to search the string -Doracle_home= and the get the value from a command line of the process using batch script

    C:\db\product\11.2.0\dbhome_1\jdk/bin/java  -server -Xmx384M -XX:MaxPermSize=400M -XX:MinHeapFreeRatio=20 -XX:MaxHeapFreeRatio=40    -DORACLE_HOME=C:\db\product\11.2.0\dbhome_1 -Doracle.home=C:\db\product\11.2.0\dbhome_1/oc4j -Doracle.oc4j.localhome=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569/sysman -DEMSTATE=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569 -Doracle.j2ee.dont.use.memory.archive=true -Djava.protocol.handler.pkgs=HTTPClient

    using wmic i am able to get the commandline. Position of -Doracle_home varies for different process. So I cannot give Token in the for loop.  


    Thanks

    It is possible but requires a set of nested tokenized for loops.  Good Luck.

    With PowerShell you can just use a RegEx expression and extract that single value:

    -match '.*-DORACLE_HOME=(?<val>.*)\s'

    That is close but I haven't tested it.

    ¯\_(ツ)_/¯

    Try something like this ...

     @echo off & setlocal EnableDelayedExpansion
    :: For testing
      set t=C:\db\product\11.2.0\dbhome_1\jdk/bin/java  -server -Xmx384M -XX:MaxPermSize=400M -XX:MinHeapFreeRatio=20 -XX:MaxHeapFreeRatio=40    -DORACLE_HOME=C:\db\product\11.2.0\dbhome_1 -Doracle.home=C:\db\product\11.2.0\dbhome_1/oc4j -Doracle.oc4j.localhome=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569/sysman -DEMSTATE=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569 -Doracle.j2ee.dont.use.memory.archive=true -Djava.protocol.handler.pkgs=HTTPClient
    ::
      for /f "tokens=1-12 delims=-" %%a in ("%t%") do (
        for %%? in (%%a %%b %%c %%d %%e %%f %%g %%h %%i %%j %%k %%l) do (
          if !Next!==True set DORACLE_Home=%%? & goto :Found
          if %%?==DORACLE_HOME set Next=True
        )
      )
      echo Not found. & exit /b 1
     :Found
      echo.The value of DORACLE_HOME is %DORACLE_home%

    OK, you make a good point, though I'm not certain you realize what that is - the outer FOR is not needed.  This would suffice ...

     @echo off & setlocal EnableDelayedExpansion
      set t=C:\db\product\11.2.0\dbhome_1\jdk/bin/java  -server -Xmx384M -XX:MaxPermSize=400M -XX:MinHeapFreeRatio=20 -XX:MaxHeapFreeRatio=40    -DORACLE_HOME=C:\db\product\11.2.0\dbhome_1 -Doracle.home=C:\db\product\11.2.0\dbhome_1/oc4j -Doracle.oc4j.localhome=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569/sysman -DEMSTATE=C:\db\product\11.2.0\dbhome_1\SLCAE205.us.oracle.com_db1569 -Doracle.j2ee.dont.use.memory.archive=true -Djava.protocol.handler.pkgs=HTTPClient
      set Next=False
      for %%? in (%t%) do (
        if !Next!==True set DORACLE.home=%%? & goto :Found
        if /I %%?==-DORACLE.HOME set Next=True
      )
      echo Not found. & exit /b 1
     :Found
      echo.The value of DORACLE.HOME is %DORACLE.home%

    Note that I added the /I switch to the second IF statement to make the test case insensitive.

    Also, I would note that your original request asked for the value of the "-Doracle_home=" parameter, not the "-Doracle.home=" parameter.
