How to check whether Weblogic is hung /up with a Unix script

Hi
I would like to write a script for monitoring the weblogic server. I want to have a script that checks the weblogic once in a while if it's up and running. if not running, will send an email to me
Please tell me what is that file name in weblogic that tells me this thing .
Thanks for reading.

This can't be answered without knowledge of your environment and how you run your WLS (version ?).
The simplest way is to use a pgrep unix command and check for the right process (i.e. the name of the wls server).
You have to keep in mind, that there might be several processes (i.e. one for the node manager one for each server).

I have check whether server is in development mode or production mode from my OSB proxy service?
I m not able to find any doc on this??Please let me know how it can be done?

There isnt any other way except for doing a Java Callout. In the callout method you can access the Domain/Server MBean for the information that you seek. Based on the callout result you can go ahead with the logic in your PS..
Here is a sample Java Code to get the Server Log Level and ascertain whether the server is in Production Mode or not.

How to check Whether the File is in Progress or used by some other resource

Hi All,
I am retrieving a file from the FTP server using Apache commons FTP.
I need to check whether the file is fully retrieved or in progress.
for now i can able to use the file which is partially retrieved. it is not throwing any file sharing exception or i am unable to find whether it is in progress.
How to check whether the file is in progress ? or The file is accessed by some other resource ?
Pls Help me.
Thanks,
J.Kathir

Hi Vamsi,
Explicitly such kind of requirement has not been catered and i dont think you would face a problem because any application that is writing to a file will open the file in the read only mode to any other simultaneous applications so i think your concerns although valid are already taken care off .
In the remote case you still face a problem then as a work around. Tell the FTP administrator to set the property to maximum connections that can be made to ftp as one. I wonder if you have heard of the concept of FTP handle , basically the above workaround is based on that concept itself. This way only one application will be able to write.
The file adapter will wait for its turn and then write the files.

joel

Hi,
Your system status should tell you that. Any logged in screen of your solution manager system --> Status. Component Version should be as "SAP EHP 1 for SAP Solution Manager 7.0" to be Ehp1 or "SAP Solution Manager 7.0"
Hope this answers your question.

How to check whether the Application Server directory exits or not

Hi,
I have a selection screen in which I give the Application server file name(UNIX file) as input. Here, I would like to check whether the Server directory exists or not.
Let us say, the path I gave in the selection screen is /usr/sap/tmp/testfile.txt . Here, the file name is testfile.txt and the server directory is /usr/sap/tmp . I would like to check whether this directory /usr/sap/tmp exists in the server or not. I am not bothered about the file name as I am going to write data into the file. I am mainly concerned about whether the directory exists in the server or not. and one more thing... this is the Application Server path not the Local path.
Can anyone help me on the same how to check whether the server directory exists or not.
Thanks in advance.
Best Regards,
Pradeep.

Also you can use the FM EPS_GET_DIRECTORY_LISTING for this purpose.
Store the directory name
    l_dpath = p_file+0(l_no).
Validate the directory of the application server
    CALL FUNCTION 'EPS_GET_DIRECTORY_LISTING'
      EXPORTING
        dir_name               = l_dpath
      TABLES
        dir_list               = l_i_dlist
      EXCEPTIONS
        invalid_eps_subdir     = 1
        sapgparam_failed       = 2
        build_directory_failed = 3
        no_authorization       = 4
        read_directory_failed = 5
        too_many_read_errors   = 6
        empty_directory_list   = 7
        OTHERS                 = 8.
If any problem occurs with the directory then display proper
error message
    IF sy-subrc <> 0.
    Display error message
      MESSAGE e018 WITH 'Problem with directory entered'(008).
    ENDIF. " sy-subrc <> 0

How to check whether system privilege are granted

How to check whether system privileges like 'create session' and other ones are granted for user.
Is there any sys table where this information is available?
Regards - Neuron

Keep in mind select * from dba_sys_privs where grantee = 'some-user' will give you a list of privileges granted to some-user directly. To get complete list of system privs granted to a user both directly an via roles use:
ACCEPT USER PROMPT 'Please enter user name: '
COLUMN PATH FORMAT A90
SET LINESIZE 132
SELECT PATH,
        PRIVILEGE
FROM DBA_SYS_PRIVS,
          SELECT 'DIRECT GRANT' PATH,
                  '&USER' GRANTED_ROLE
            FROM DUAL
         UNION ALL
          SELECT LTRIM(SYS_CONNECT_BY_PATH(GRANTED_ROLE,'->'),'->') PATH,
                  GRANTED_ROLE
            FROM DBA_ROLE_PRIVS
            START WITH GRANTEE = UPPER('&USER')
            CONNECT BY PRIOR GRANTED_ROLE = GRANTEE
WHERE GRANTEE = GRANTED_ROLE
/Now on top of privileges granted to a user, user also has privileges granted to PUBLIC. To get privileges user receives via PUBLIC run the above script specifying PUBLIC at the prompt.
