Existent components disabled for maintenance, EPM 11.1.2.2 11.1.2.3

I'm trying to do a maintenance release installation of EPM 11.1.2.3 on top of 11.1.2.2 and am getting "ERROR: There are existent components that are disabled for maintenance install.  Please, review the reasons why the components are disabled, resolve issues and retry maintenance install."
How do I tell which components are "disabled for maintenace"?  Are they the ones that are checked but greyed out in the list of components to install in configurator?
The one document I found says that the components are missing in the download but I have downloaded and extracted the parts indicated in the README for Interactive Reporting,which is the only component we are using and are the same ones as for 11.1.2.2 release.
Could some one tell which logs would have information about this, if any?
This is on a Windows 2008 r2 server, with SQL Server 2005 repository database.

You could try downloading and extracting all the parts just to be sure you have all the required files.
There was a similar question which the poster said downloading and extracting the OHS file resolved the issue EPM 11.1.2.3 Upgrade Error: there are existent components that are disabled

  • Temporarily disable STMS/MPXIO for maintenance

    Hi-
    Looking for advice. I have six active/active arrays using STMS/MPXIO, Sun/Qlogic FC4 hbas and V40z's running S10_U3 x86. Each array has 84 LUNs, with 8 paths, presented to around 20 hosts. Periodically I need to bring down one of the arrays for maintenance (firmware upgrades). When the array is offline STMS/MPXIO generates lots of inquiriy traffic trying to get the paths back online. During a particulary nasty maintenance cycle, my Oracle RAC system (connected thru the same SAN) paniced since it was taking too long to get to the Oracle device.
    During my maintnenance cycles I'd like to disable MPXIO for the particular array, so that the retry/inquiry traffic is suppressed and will allow my other arrays to continue production.
    I think I could use luxadm disable /dev/rdsk/cXtYdZs2 for the mpxio devices of all luns in that array (create a sceript to do this) and follow up with an enable after the work is done.
    I'd like to know if anyone has done something like this and if it is also something I could do with the new mpathadm command that is/will replace the luxadm command.
    Thanks

  • How to disable alerts when OMS is down for maintenance?

    Hi,
    When we bring down OEM 12c application for maintenance for a period of time, lots of alert e-mails got sent out due to the fact the OMS is down. These alert e-mails contains the following info in the e-mail subject line:
    EM Event: <Severity>:<target-name> - Agent is unable to communicate with the OMS. (REASON = Agent is Unreachable (REASON : Agent to OMS Communication is brokenFailure connecting to https://oem12-stg:4900/empbs/upload
    These alert e-mails are not necessary and annoying. Does anyone know if there is a way to disable these alert e-mails temporarily during the OMS maintenance window?
    Thank you for the help.

  • "This Apple ID has been disabled for security reasons" Every few weeks

    I have had an iTunes account for years with no issue. Lately, I have been receiving the dreaded "This Apple ID has been disabled for security reasons" message every few weeks on my iPad 2(currenly, my only iOS device). I go through the process of reauthorizing my password and info and it works again for a while, then happens again some time later. It's getting annoying. I'm not sure what's changed. Only two computers are authorized to use my account and I am the only one who can log into either of them. No one knows my info and I live alone.
    The only thing I can think is that it's a bot spamming my e-mail address and passwords in an attempt to hack my account. If that's the case, am I really going to have to go through this every few weeks just to use my iPad? Don't get me started on how stupid it is to have to type in your password to update existing apps. And that's usually when I find out, not when I actually purchase one.
    Is anyone else having this issue? I'm wondering if it's more widespread. Some time ago, a chinese app was mysteriously purchased on my account. Apple refunded the purchase and reset my password. That was about the time that all of this started. The reviews on the app left no doubt that it was happening to numerous people and I have no idea how they would have forced a purchase on so many user accounts.

    Everyone should keep a few things in mind:
    This is an occasional problem affecting a vanishingly small percentage of the installed base. Look at the numbers of actual instances in just this thread, look at the gaps in time, etc.
    Many many more ... me for example ... have never seen it at all. That doesn't mean it's not an irritation for those afflicted, but it does mean that it's not something likely to be seen as a critical issue affecting the whole base.

  • My iPod Touch 4th gen is disabled for 22,000,000 minutes. I remember the passcode, and I can't restore.

    My iPod Touch 4th gen is disabled for 22,000,000 minutes. I have looked all around the Apple support communities and I always find the same "solution", which is to put it into DFU or recovery mode and restore from a backup. Here's my problem: My computer crashed awhile back and I had to completely start over from scratch. So, unfortunately, a backup of my device no longer exists on this computer or any other computer.
    Is there any way I can simply get rid of the disable? I remember my passcode, so that isn't a problem, all I need is to be able to input my passcode.
    Or, do I absolutely have to restore to factory settings, and lose all my data?
    By the way, I hope it does not matter, but I can't remember the IOS is was last updated with.
    Thanks.

    Disabled
    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

  • Auto update stats disabled for a user Database in Sql server

    While trying to improve the performance of few queries, we found via execution plan that there were lot of Index/Clustered index seeks. Therefore:
    First thing we did, was to check our Re-indexing and update stats job which runs weekly for this user DB ( Around 400 GB in size and is used 24*5). The job was running fine.
    Later when we ran SP_Blitz, we came to know that auto-update-stats is disabled for this user DB. We expected this to be a possible cause and change it from false to TRUE(Auto update stats)
    Also, per SP_blitz there are user-created statistics for this DB. When ran the query to check how many, we saw around 7K user stats out there.
    So my question would be 1) setting the Auto update stats to TRUE would require a reboot or once changed i need to track the performance and 2) Should we consider dropping those user created stats or manually look into them one by one.
    How should we proceed on this, please suggest, thanks!

    There may be good reasons for having auto-stats off, but those cases are not very common. It makes a little more sense to turn if off on table level. An example of the latter is a relatively small table, say < 100000 rows where not many new rows are added,
    but the existing rows are being updated frequently. This will trigger autostats, but probably without much benefit.
    But if you have a system which is very busy during peak times, you may not want autostats take resources during those hours. But if you turn off autostats, you will need to make sure that stats are updated in some other fashion.
    Here is a query that you can use review when your statistics last were updated:
    SELECT o.name, s.name, stats_date(o.object_id, s.stats_id) AS lastupdated
    FROM   sys.objects o
    JOIN   sys.stats s ON s.object_id = o.object_id
    --WHERE  s.user_created = 1
    ORDER BY lastupdated
    7000 user-created statistics sounds a little excessive, but I guess they were added to compensate for the autostats that SQL Server were not permitted to create. I would not recommend dropping these statistics, as SQL Server would spend cycles on recreating
    them.
    You should not have to restart SQL Server for the Auto-update stats setting to take effect; it takes effect immediately.

  • Schedule for Maintenance and Support

    When do you expect to be at a point where you set product price and maintenance cost?
    Also, I assume that you will give existing MATRIXx customers a 'grace period' during which we can secure funds to resume paying for maintenance and support, right? I would expect something like 90 to 120 days in the grace period.
    Thanks.

    Michael -
    We are currently finalizing our price list, which will include product prices, maintenance, and all of NI's policies concerning maintenance and support.

  • What r the trns code for maintenance view, help view and projection view

    hi all
    what r the transaction code for maintenance view, help view and projection view
    can anyone tell me how to create maitenance, help and projection view.
    with an example
    regs
    hari

    <b>What is the Different Types and Usage of Views
    The followings are different types of views:</b>
    - <b>Database View   (SE11)</b>
    Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set. 
    In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
    - <b>Help View    ( SE54)</b>
    Help views are used to output additional information when the online help system is called. 
    When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view. 
    -<b> Projection View  (SE11)</b>
    Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
    A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
    <b>- Maintenance View   ( SE54 )</b>
    Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.

  • Multiple PR doc type for Maintenance order - Non stock item category

    For non-stock item requirement in PM, we create a maintenance order and indicate item category as "N" in components tab. Accordingly a purchase requisition is created as per configuration. We have assigned PR doc. Type “FO – Framework requisition” for Maintenance Order Category.
    SPRO - PLANT MAINTENANCE & CS - Maintenance and Service Processing - Maintenance and Service Orders - General Data - Define Account Assignment Cat. and Document Type for Purchase Requisitions
    Now according to the new requirement, we need to have different PR Doc type as per CONTROL KEY mentioned in the Maintenance Order.
    Example:
    If the Control Key is “PM01 - Plant maintenance – internal” the purchase requisition document type should be “NB – Purchase Requisition”. If the Control Key is “PM03 - Plant maintenance-External(services)” the purchase requisition document type should be “FO – Framework Requisition”.
    Please advise how to configure the same.
    Regards
    Sathish Kumar Balakrishnan

    Hi Partha,
    This is a simple enhancement. In our scenario, we had configured PR document type "FO" in SPRO settings for "Document Type for Purchase Requisitions".
    Hence to have "NB" PR document type whenever material components are being indented through maintenance order, we used this enhancement COZF0002
    Please instruct your abaper to add similar logic, as shown below.
    Enhancement:COZF0002
    Functional module:EXIT_SAPLCOZF_002
    Include: ZXCOZU02
    Logic:
    IF sy-tcode eq 'IW21' or sy-tcode eq 'IW22' OR sy-tcode eq 'IW28'  OR sy-tcode eq 'IW31' or sy-tcode eq 'IW32'  OR sy-tcode eq 'IW38' .
      IF resbd_imp-postp = 'N'.
        eban_ord_cust_chg-bsart = 'NB'.
      ENDIF.
    endif.
    Hope this helps.

  • Customizations are disabled for the node "ProposedJobVO.xml"

    Hi,
    We are trying to add extensions to a fusion Application. When i have created an Application 'Fusion Customizations Application'.
    In the Role 'Oracle Fusion Applications Administratror Customizations', and in Customizable Archive, Some Business Components are Not customizable while some of them are Customizable.
    getting below error in Log file
    Customizations are disabled for the node "ProposedJobVO.xml" because it is not part of the project contentset.
    Does this mean we cannot modify this VO or we need to do anything else to get these components included in Project Content Set?
    Thanks
    Kaja

    "Customizations are disabled for the node xxxx because it is not part of the project contentset". This warning is logged if you try to open a node for customization in customizaion role IN FA environment from Application Resources->connections->customizable archive ,
    as this node is not a part of project. In order to add it to the project you will have to right click on the node and select customize this will add the node to the virtual content set of project.
    Now this node will be available under project and can be customized.

  • ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt

    what are the scenarios that we have to use the below statement.
    RMAN> ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;

    first you have to understand why we allocate channel for rman..it crates a session to target database,To manually allocate a channel, which is a connection between RMAN and a database instance. Each connection initiates an Oracle server session on the target or auxiliary instance: this server session performs the work of backing up, restoring, or recovering backup sets and copies.
    Restrictions and Usage of this command
    Execute this command only at the RMAN prompt. This command cannot be used within a RUN block.
    The target instance must be started.
    Do not specify a channel ID.
    You cannot allocate a maintenance channel to a shared session.
    You cannot prefix ORA_ to a channel name. RMAN reserves channel names beginning with the ORA_ prefix for its own use.
    Manually allocated channels (maintenance or normal channels) and automatic channels based on configured settings are never mixed. To perform maintenance on both disk and SBT simultaneously using manually allocated maintenance channels, you must allocate both SBT and DISK channels explicitly.
    If you use ALLOCATE CHANNEL FOR MAINTENANCE, then RMAN uses the following convention for channel naming: ORA_MAINT_devicetype_n, where devicetype refers to DISK or sbt and n refers to the channel number. For example, RMAN uses these names for two manually allocated disk channels:
    ORA_MAINT_DISK_1
    ORA_MAINT_DISK_2
    You can allocate multiple maintenance channels for a single job, but you should only use this feature in these situations:
    o
    To allow crosschecking or deletion of all backup pieces or proxy copies, both on disk and tape, with a single command
    o
    To make crosschecking and deleting work correctly in an Oracle Real Application Clusters configuration in which each backup piece or proxy copy exists only on one node
    here is some example of this command you should check this..
    Deleting a Backup Set: Example This example deletes backup sets from tape created more than a week ago:
    ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;
    DELETE NOPROMPT BACKUP OF DATABASE COMPLETED BEFORE 'SYSDATE-7';
    Crosschecking Archived Logs: Example This example crosschecks all archived logs on disk and tape. For disk, the preconfigured disk channel is used; for tape, an SBT channel is allocated manually. If the logs are not found, then RMAN marks them as EXPIRED in the repository:
    ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;
    CROSSCHECK ARCHIVELOG ALL;
    Crosschecking on Multiple Nodes of an Oracle Real Application Clusters Configuration: Example In this example, you perform a crosscheck of backups on two nodes of an Oracle Real Application Clusters configuration, where each node has access to a subset of backups. It is assumed here that all backups are accessible by at least one of the two nodes used in the crosscheck. Any backups not accessible from at least one of the nodes are marked EXPIRED after the crosscheck.
    ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE DISK CONNECT 'SYS/change_on_install@inst1';
    ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE DISK CONNECT 'SYS/change_on_install@inst2';
    CROSSCHECK BACKUP;

  • Web Dynpro Development Components missing for MSS

    Hey Guys...
    The following BPs are installed on our landscape:
    ○       Business Package for Manager Self-Service (SAP ERP) 1.3
    ○       Business Package for Common Parts (SAP ERP) 1.3
    ○       Business Package for Project Self-Service (SAP ERP) 1.0
    ○       Business Package for HR Administrator (SAP ERP) 1.1
    The ECC is EHP 3, SP 14 and EP is 7.0 SP 14
    I've been trying to set up iViews for MSS but I see that all Web Dynpro Applications specified in the technical information of iViews are missing. I searched for Web Dynpro Development Components in the EP and all MSS related WDC are just missing.
    According to SAP Help Documentation (http://help.sap.com/erp2005_ehp_03/helpdata/en/76/77594d165144a1a9bff9aae1e26b26/content.htm) these are required:
    Web Dynpro Development Components:
    ○       PCUI_GP
    ○       MSS
    ○       SAP_PSS
    Where can I get them??? Is it possible our basis didn't install the right Business Package?

    Seems you have got right business packages, though have a look at  note [1303362|https://websmp230.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/sapnotes/index2.htm?numm=1303362] to confirm dependency.
    "but I see that all Web Dynpro Applications specified in the technical information of iViews are missing."
    Well this could be because of errorsome business package deployment, you can still check list of deployed components from SDM and if there is any error log for deployement, you should try to deploy them again(update existing components).
    Hope this helps. If not then probably you should go Content Admin - WebDynpro  and see list of application listed under MSS.. if those referred applications are available then try to execute them.
    And last one.. if you "think" they wont run.. or you have actually tried to run MSS and none of applications are working. you should be able to run standard package without any major configuration chanegs.. so give it a go.. and see if you encounter any error.

  • What is the best app for Maintenance/Cleanup for my mac? Do I need Virus Protection?

    What is the best app for Maintenance/Cleanup for my Mac? Do I need Virus protection?

    How to maintain a Mac
    Make two or more backups of all your files
    One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.
    Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups.
    In fact, don’t rely exclusively on any single backup method, such as Time Machine.
    If you get an indication that a backup has failed, don't ignore it.
    Keep your software up to date
    In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
    Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
    Don't install crapware
    ...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
    It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.
    As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
    Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
    Don't install bad, conflicting, or unnecessary fonts
    Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
    Deactivate or remove fonts that you don't really need to speed up application launching.
    Avoid malware
    "Malware" is malicious software that circulates on the Internet. This kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.
    There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least one day ahead of the defense. You can’t rely on third-party "anti-virus" products for protection either. What you can rely on is common-sense awareness—not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
    Don't fill up your disk or SSD
    A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
    While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
    Relax, don’t do it
    Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
    A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.
