E-Recruiting and HR Instance Separate Instance

Hi,
If E-Recruiting and HR has Instance Separate Instance, how do we get the Internal Candidate from HR system? By ALE? If yes, which program do we run to trigger the ALE?
If ALE, what is happening when ALE is running? Will it create CP and BP? When NA will get created?
How to assign a Login Id to Internal candidate?
Let me know, if I’m not clear.
Regards,
...Naddy

Hi Naddy,
yes if you have a standalone installation the internal candidates are created via ALE (at least in the common cases).
The common configuration for an e-recruiting ALE transfers organizational units, positions, jobs and employees. For the first 3 objects the inbound processing is done in the standard way. For employees the system uses the BADI HRALE00SPLIT_INBOUND with implementation HR_INB_PROCESS_IDOC to create central persons, business partners and candidate object.
The user ID is taken from IT0105 subtype 0001. If the employee has no user assigned the system will generate one. To get hands on the login information (if there is no SSO) the user can request the password in the webfrontend. This requires that the user is maintained and known to the candidate or the emailadress is maintained in IT0105 subtype 0010. If not at least one of these 2 options is available for each candidate it would be an issue for the implementation project to deal with.
The Idocs are created via T-Code PFAL (report RHALEINI) for the initial load of data. After this RBDMIDOC is used to create Idocs from the change pointers.

  • Need a tool to create Development and Test instance of a Production db

    I am very new to Oracle and have previously worked with SQL Server 2005/8 only.
    My current company only has one instance of the Oracle database (which is production) and until now, all development and testing used to take place on the same instance (what a mess!!).
    Anyways, we have now decided to create a development and test on a separate physical machine. We are on Oracle 11g on Windows 2008 Server.
    In SQL Server, it used to be fairly simple, just take a full backup of the database and restore it on another box with SQL Server and we had a new instance of the same database.
    Can someone point out a simple technique to create these development and test instance in Oracle. Essentially, we want to clone the database. Are there any tools available that can make this task simple.
    Thanks.

    Welcome the the forums !
    I believe this question is better suited to the "Database - General" forum (General Database Discussions but here is my take.
    You will first need to clone the Oracle binaries (ORACLE_HOME) - see MOS Doc 1154613.1 (Master Note For Cloning Oracle Database Server ORACLE_HOME's Using the Oracle Universal Installer (OUI))
    Then clone the database - see MOS Doc 458450.1 (Steps to Manually Clone a Database)

  • Create dev and test instances of Apex on the same server and database

    I have a dev and prod instances of Apex on different servers. I want a test instance on the same server as the dev instance.
    I am using workspace export/import so all instance workspaces have the same workspace id. The application ID is the same on each instance, in the same workspace. This allows pages to be exported/imported in the differenct instances.
    My question is (I am sure it is obvious) can I have more than one instances of Apex on the same database (dev and test) and have each instance have identical Workspace IDs, etc.
    Sam

    Hi Sam,
    But you can have more than one database on the same server.
    What we do is create a separate database for each APEX versions we are supporting (we still have a customer using APEX 2.0).
    All the databases are accessed with the same APACHE config. All you have to do is change the DAD and have a separate dad for each database (i.e. each APEX versions).
    ex : /pls/apex_dev /pls/apex_test
    This way , I can run different APEX versions on the same server.

  • Central NetWeaver Installation and DB Instance on same host?

    HI all,
    Would like to ask a question about NetWeaver installation.
    If I choose central installation, means Central Service Instance, DB Instance and Central Instance will be on the same host, but can my DB, say SQL Server reside on separate host?
    If not, is it correct that I have to choose distributed installation? So if distributed installation, can I install Central Service instance and Central intance on one host, and DB instance and SQL Server on another host?
    Thanks,
    Kelvin

    Hi KL:
    You can get this answer directly from the Installation Guides.

  • BPEL process having one file and one FTP adapters and single instance

    hi All,
    We have a customer requirement where we have to read from FTP location (XML every 5 Mins) and Local file system (CSV every Min).
    There is no correlation between the files ...this file data could be same, only difference is some user will copy it in FTP location some in the local file system.
    We need to pickup these file as it arrive in respective locations and read one particular value from it and set a global value and do some processing.
    Next time when file arrives in any location (FTP or local) it should pickup the file compare the particular value to the global value which was set at the previous stage and do processing based on whether is greater or lesser and this reading should go on.
    As files needs to be picked up every Minute, customer doesnt want to initiate multiple BPEL process ...everything should happen in the single instance.
    how do solve this , pls help.
    Regards,
    Surendra

    Hi Surendra,
    When you say " everything should happen in the single instance", I hope you mean everything shud happen in the same BPEL process irrespective of the location(FTP or local) where file is copied.
    So, what you can do here is instead of using a single receive activity. Make use of Flow activity and put 2 separate receive activities( one each for polling local and FTP location) in parallel.
    After that you can separately act upon the variable from both the receive activities.
    thanks

  • Content type, list definition and List instance - query

    Dear all,
    I created a list content type, list definition and list instance for a SessionsList.
    I did mistake when created a event receiver file where field name is RegistrationsInfo - did typo error as RegistrationInfo. This field I want to make it as false in the ShowInNewForm= false
    When I deploy it with event receiver file - I am getting stack trace error stating that the RegistrationsInfo field is missing.
    Without event receiver file - when I deploy the solution and checked the field name - it is showing rightly as RegistrationsInfo.

    Sathya

    Hi Sathya,
    Seems the field “RegistrationsInfo” is not been found when deploying with Event Receiver, a possible reason is that it might be damaged.
    As a workaround, I suggest you retract the solution from your farm, make sure the “RegistrationsInfo” field is deleted using PowerShell, then create another project with the same
    content and perform the deployment again.
    About how to delete a field using PowerShell for your reference:

  • How to know the size of a client and an instance ?

    hi,
    How to know and measure the size of a client and an instance ?
    comment and advice will be appreciated.
    regards,
    kent

    Hi Kent,
    I always measure the size of the complete DB (instance) with DSPLIB *PRINT in batch - the very last line is the size. You could have a look into DB02 as well.
    The client size is more complicated ...
    You could do a "test-client-copy" - there it reports a size - but this size is far too small normally ....

  • How to sinck data between  production and R12 instance

    Hi,
    I am working on Oracle Apps up-gradation project.
    Now I have upgrade 11.5.7 to R12 (12.0.4) successfully. I started up-gradation task with 1 May of production data (backup) on new machine.
    Client wants to live R12 from 1/August/2009.
    Please suggest how to sinck data between production and R12 instance.
    Thanks
    Anup

    Hi,
    It is not possible to do what you propose (sync data from an 11.5.7 system to a 12.0.4 system). You will need to re-run the upgrade against the August 1 data, following your original upgrade procedures.

  • Oracle11g RAC with partitioning and cross instance parallel query problem

    I have set up a 300gb TPC-H database using a 4 node RAC environment (8 cpu per node, 16 GB memory, 2 GHz processors) the system is served by 2.5 terabytes of SSD for its IO subsystem managed by a combination of ASM and OCFS2.
    When I run a large parallel query (number 9 in the TPCH query set) I get:
    ORA-00600: internal error code, arguments [kxfrGraDistNum3],[65535],[4]
    with all other arguments blank. There were some reports of this in version 9, but it was supposedly fixed. Has any one seen this behavior or have a work around?
    Mike

    Good Idea! Why didn't I think of that? Oh yea...I did. Unfortunately TMS CSI is an update only partner type CSI so I cannot submit a SR. The 600 lookup was how I found the old stuff, but it didn't have any 11g references. I hoped maybe someone in the community had encountered this and had a workaround. By the way, the querey looks like so:
    select
    nation,
    o_year,
    sum(amount) as sum_profit
    from
    select
    n_name as nation,
    extract(year from o_orderdate) as o_year,
    l_extendedprice * (1 - l_discount) - ps_supplycost * l_quantity as amount
    from
    h_part,
    h_supplier,
    h_lineitem,
    h_partsupp,
    h_order,
    h_nation
    where
    s_suppkey = l_suppkey
    and ps_suppkey = l_suppkey
    and ps_partkey = l_partkey
    and p_partkey = l_partkey
    and o_orderkey = l_orderkey
    and s_nationkey = n_nationkey
    and p_name like '%spring%'
    ) as profit
    group by
    nation,
    o_year
    order by
    nation,
    o_year desc;
    the other 21 queries, all using the same tables and degrees of paralell and cross instance settings, executed ok.

  • Failover clusterign... How similar do the primary and failover instance need to be in a failover cluster?

    How similar do the primary and failover instance need to be in a failover cluster?
    Does the number of database have to match, naming, general config etc...
    Mr Shaw

    In failover clustering, you use shared storage so the number of databases is irrelevant since only one node can see/access the shared storage at any given point in time. Ideally, the server configuration should be the same on all of the nodes to minimize
    potential issues that may impact downtime. However, you need to consider licensing/# of CPU-cores and implementation cost, especially if you are only using the other nodes as standby. As far as licensing is concerned, the standby has to have the same or fewer
    number of CPU-cores as the primary node to be covered by licensing. Besides, you don't want your standby node to be more powerful than your primary node. This is why the option to have a hybrid deployment of having a physical server as the primary node and
    virtual machine for standby nodes is now supported.

    We says when we want to distribute the workload on servers we requires central instance and application servers.
    Normally it is not known to common users where they are logging into...but they can login directly usign the specific Instance details of servers.

  • Central instance and SAP instance

    hello,
    Im confusing with Central Instance (CI) and SAP instance (Application Instance)
    According to my understanding, i think SAP instance is running on all the Aplication servers. (if having 4 Application servers, in all those servers, SAP instance is running concurrently)
    But Central instance is running on 1 of the Application servers only.
    - How will the SAP decides on which Application should run the central instance.
    Will that CI change automatically time to time.... or do we need to allocate 1 Application server as CI server, when doing the installation.
    Is there any relationship between Message server and Central instance.
    Does CI contains message services and enqueue service...
    plz help me to reslove these issues
    Rgds,

    *CENTRAL INSTANCE: The SAP Central Instance (CI) is a standalone SAP Basis
    unit which provides services used by clients connected to the SAP system.
    Among these services are the Message server and the Enqueue server, which
    run only on the single SAP Central Instance. The Message server maintains a
    list of all available resources in an SAP system, determines which instance
    a user logs on to during a client connect, and handles all communication
    between SAP instances. The Enqueue server is used by SAP to administer the
    lock table in a distributed SAP system. If the CI
    server hosting the Enqueue service fails, all SAP transaction locks that
    have not yet been committed are lost. R/3 guarantees that no user can
    perform a transaction while the Enqueue service is unavailable in order to
    guarantee database consistency. Placing the Enqueue and Message services
    together on the CI is recommended by SAP since the Message service must
    always access the Enqueue service for inter-process communication. These
    services provide critical SAP functions that, by existing only in the SAP
    Central Instance, suffer from being a single point of failure in the SAP
    environment. Obviously, the CI, which contains the Enqueue and Message
    services, needs to be restarted as quickly as possible following a failure
    so that normal operations can resume.*
    Central Instance Has Message server and an enque work Process,
    Application Server or dialog Server : Does not have message
    server but have work process to reduce the Load on CI*
