  • Unable to read software component version from System Landscape Directory "

    I've worked in past creating/importing SWCV, but this is new system PI7.0 and stuck.
    A) Is my understanding on resolution correct?
    Should I go and apply notes 940309 and create client copy of existing client 001
                                        OR
    change role of client 001; SXMB_ADMIN -> 'Integration Engine Configuration' to 'Integration Server'
    I have no problem in using client 001 as Integration server, all I want is import of SWCV to work. Thanks. Appreciate the help.
    B) Here is what I have done and the error:
    1) Followed weblog below and created product, software component, technical system, business sytem in SLD.
    /people/srinivas.vanamala2/blog/2007/02/05/step-by-step-guide-xml-file-2-xml-file-scenario-part-i
    2) When I import the SWC from integration repository getting error
    (Unable to read software component version from System Landscape Directory "server:5<system number>00").
    C) Pointers used from the forum to debug the issue, but still no luck
    Below are the points checked from the forum and all steps are correct, but still have issues with the import
    1) check the RFCs SAPSLDAPI, LCRSAPRFC, connection test pass as the program ID registered with Jco
    2) T-code SLDCHECK no errors (followed http://help.sap.com/saphelp_nw04/helpdata/de/78/20244134a56532e10000000a1550b0/content.htm)
    3) T-code SLDAPICUST got user PIAPPLUSER, pwd is correct (reset the pwd)
    4) logged using PIAPPLUSER http://server:port/sld and it works
    5) One of the weblog SLD Check Failed (LCR_LIST_BUSINESS_SYSTEMS function doesn't work) referred to apply notes 940309
    Notes: 940309
    You are installing 'SAP NetWeaver 2004s SR1 ABAP+Java' Usage Type 'NetWeaver Process Integration (PI)'.

    applied portion (PIPostInstallProcess) of OSS notes 940309 and it resolved.
    Note:
    I still retained client 001 and didn't do client copy as mentioned in the notes. The wizard based CTC tool helped. Here are the details if someone has similar issue and want to know further details:
    A NetWeaver Process Integration (PI) Installation (ABAP+Java) has two parts: Installation and configuration. The former is done by the Installer, the latter by the 'Central Template Configuration' (CTC) Tool.

  • PDDocSaveWithParams does not change PDF version from 1.8 (Acrobat 9, Acrobat X) to 1.4

    Dear all,
    this post seems similar to this discussion:
    http://forums.adobe.com/message/1160826#1160826
    but it is not.
    Our customers prepare documents to be presented at regulatory  authorities, and it is required that these documents have PDF Version  1.4, are linearized, etc. In a plug-in we change the document properties accordingly. This used to work fine with Acrobat versions from 6 to 9. Then came Acrobat X.
    We detected the problem with a document created with Acrobat PDFMaker 10.0 for Word: a very simple 1-page 3-lines document with no Acrobat X features.
    When using Acrobat X, after calling PDDocSaveWithParams, the PDF version was not changed as required. (We check this calling PDDocGetVersion from the plugin after saving.)
    Doing the same conversion with Acrobat 9 seemed to be OK: PDDocGetVersion reported PDF Version 1.4.
    But when opening the converted document in Acrobat X, it still reported "PDF Version: 1.7 Extension Level 8 (Acrobat X.x)".
    Opening it in a text editor showed that the header was "%PDF-1.4", but it still had "<</Extensions<</ADBE<</BaseVersion/1.7/ExtensionLevel 8>>>>..."
    With Acrobat 8 and below, the version could not be downgraded, but this was reported correctly.
    Downgrading the version directly via the "Optimize" function of Acrobat X worked.
    I could not test Acrobat 9, since I have no Professional version available.
    In Acrobat 8 Prof, I saw the message "This file appears to use a new format that this version of Acrobat does not support.", and the "Optimize" function was disabled.
    Now I have the following questions:
    (1) Is it a known problem that PDDocSaveWithParams does not downgrade the version with Acrobat X ?
    (2) Is it a known problem that PDDocSaveWithParams does not downgrade correctly with Acrobat 9 ?
    (3) Is it a known problem that Acrobat9 wrongly reports the PDF Version of the document, in this case ?
    (4) Why is downgrading (or optimizing) disabled for Acrobat 8 and below ?
    Thank you !

    Remember that as of PDF 1.4, the version number in the PDF header can be overridden via a /Version key in the /Catalog dictionary.  In addition, the presence of an /Extension dictionary (ISO 32000-1) will also override the header version. 
    The header version is JUST A HINT - it is NOT a guarantee of any sort.
    Based on both of the above, neither of your "bugs" are bugs. 
    Acrobat 9 (and I assume X as well) are reporting correctly. If you have a PDF that you believe IS being reported incorrectly, please post! 
    If the Extensions dict is present, the Save command will NOT override it since it takes precedence.

  • Question Regarding upgrading weblogic server from 10.3.5 to 10.3.6 in OBIEE

    Here is what was done.
    1) Create a 11.2.0.3 database and create the repositories required from Enterprise BI Install
    2) Install OBIEE 11.1.1.6.0. The option chosen was 'Enterprise Install' which installed and configured the domain and the instance
    3) Shutdown all services and apply Patches to bring the install to 11.1.1.6.8
    The application is working fine. But In production, I plan to the use install method of
    1) Install Weblogic 10.3.6 and Use JRockIt
    2) Install OBIEE 11.1.1.6.0 and plan to choose 'Software Only Install)
    3) Apply the 11.1.1.6.8 patchset.
    4) Configure the doamin.
    Here is what I plan to do in the Development Environment
    1) Just to keep the Version of Weblogic Version, the same in development also, I plan to upgrade the Weblogic in Devlopment install to 10.3.6 as the Weblogic Version that comes with OBIEE install is 10.3.5.
    2) Aslo use the latest version of 64-bit install of JRockit
    Please point me to the documentation that would help me achive this.
    Thanks a ton. This forum is awesome.

    Okay. This might help you then. Refer to :
    1.Upgrade the Weblogic in Devlopment install to 10.3.6 - http://gerardnico.com/wiki/weblogic/patch

  • Problem when using weblogic.jspc from an IDE

    I am trying to call JSPC from an IDE (as part of an Eclipse Builder). To optimize performance I want to avoid to spwan a new process. So I am trying to call weblogic.jspc's main method directly from the IDE. Everything works fine for simple simple pages.
              But when the page refers to a tag library with a tag providing a TagExtraInfo class, weblogic.jspc complains about the class not extending the TagExtraInfo base class although it does:
              Errors encountered while compiling 'D:\vrp-localdeploy\applications\wot\WOT' :
              Translation of /rentalcar/tiles/i18n/CarCapacityView.jsp failed: (line 17): Error in using tag library uri='/tags/i18n' prefix='i18n': For tag 'bundle', extra info class 'org.apache.taglibs.i18n.BundleTEI' does not extend javax.servlet.jsp.tagext.TagExtraInfo
              I could not figure out what exactly causes the problem. Using exactly the same settings workes just fine.
              Any suggestions?

    The full stack trace reads as follows:

              <p>
              Unfortunately it doesn't really give any real reason - it is a general piece of code in jspc to report problems.
              <p>
              But I dug a lot bit deeper into the code and realized that the original problem is a ClassCastException in line 1290 of class StandardTagLib, which reads as follows:
              <p>
                   tagextrainfo = (TagExtraInfo)Beans.instantiate(classloader, s3);
              <p>
              This looks quite obvious that the class named by s3 simply is no extension of TagExtraInfo, but unfortunately the only class with that name being referenced by the class path does extend this class. I wondered what the problem might be and came up with the following answer:
              <p>
              The class of the bean instantiated by Beans.instantiate extends a class with the name "javax.servlet.jsp.tagext.TagExtraInfo" which is cast to another class with exactly <b>the same name, but a different class loader</b>. Since neither of the class loaders is parent of the other one, both classes are not considered being the same class although they have the same name. Sounds weird, but exactly this is the problem!
              <p>
              Where does it come from and why it works fine when the tool is executed in a separate thread or on the console?
              <p>
              From my understanding the problem is caused in line 395 of the class weblogic.jspc:
              <p>
                   GenericClassLoader genericclassloader = new GenericClassLoader(classpathclassfinder);
              <p>
              This line of code creates a class loader not knowing a parent class loader by which the class weblogic.jspc was loaded. All classes weblogic.jspc is using or calling will be loader by either the same or a parent class loader - this is important to understand. Since TagExtraInfo is directly referenced by StandardTagLib one instance of the class object (the object of type class) will be generated and linked when the class StandardTagLib is instantiated for the first time by the class loader which loaded weblogic.jspc (or by its parent). This is consequence which can not be avoided.
              <p>
              But now look at line 1290 of class StandardTagLib: It explicitly requests the class to be loaded by the GenericClassLoader instantiated in line 395 of the class weblogic.jspc. This class loader, off course, is not aware of the same class just being loaded by another class loader since it has no knowledge of it. It simply creates a fresh copy of the class object, which only differs in the reference to the class loader which created this class object.
              <p>
              Actually, I figured that the following line of code replacing the upper one, would resolve the problem:
              <p>
              GenericClassLoader genericclassloader = new GenericClassLoader(classpathclassfinder, this.getClass().getClassLoader());
              <p>
              Doing this, the GenericClassLoader would know its logical parent by reference and would implicitly - thanks to the implementation of java.lang.ClassLoader - try to find the class using its parent first, would find a valid class, and hence use the same instance of the class object instantiated by the parent class loader. The problem would be solved.
              <p>
              It works fine in the console or under a running application server, because they will always have the weblogic jar in their system class path. ClassLoaders not having a parent are implied to have the system class loader as their parent - the piece of code does work in this case.
              <p>
              Under Eclipse this is no option, off course. We would restrain us to exactly this version of the APIs used by the weblogic version in the system class path.
              <p>
              I was trying to patch this myself by extending weblogic.jspc by my own class to pass on a proper class loader knowing its parent, and I was sort of successful: The problem disappeared. But I can't gain exactly what I am looking for, because the method runJspc with four parameters (around line 447) of weblogic.jspc is private to the class and its public brother always passes true to this method as the fourth parameter - causing jspc to recompile all JSPs instead of just the requested ones.
              <p>
              Everything refers to WL81SP3.
              <p>
              That's were I got stuck currently. I have read some postings about this problem in the internet - some dating far back into the history. So, I have the impression that there have been some folks around with the same problem. I think the patch I suggested does not any harm and I could simply use jspc in my builder without any problems.
              <p>
              Regards,
              <p>

  • Weblogic.version gives java error after install of D33T

    Hi,
    I just installed patch D33T (Oracle WebLogic Server Patch Set Update 10.3.6.0.4) - released April 2013. Before installing the patch, I checked my weblogic version (running setWLSEnv and java weblogic.version) following the instructions in the readme and the command worked.
    The patch installed fine, I then checked the version again (first doing setWLSEnv and then running java weblogic.version) - however this produced the java error 'NoClassDefFoundError' - could not find the main class: weblogic.version.
    I found a blog entry that suggested adding the weblogic.jar to the classpath, so I did that, then exported the classpatch, ran the setWLSEnv.sh again and tried the java weblogic.version command again - but still received the java error. I then tried running the command from the folder containg the weblogic.jar and still no luck.
    Anyone have any ideas why this may be producing errors?
    Thanks,
    Connie
    Environment info: RHEL 64 - Weblogic SErver 11gR1 (10.3.6.0) - The servers start and seem to be running fine after the patch install.

    I was trying a few more things after I sent my last reply and wondered if my classpath and path values might have not had correct values after running setWLSENV.sh
    When I echo'ed their values, they came back without any of the values being set by setWLSEnv.sh
    I then set them by copying and pasting the values echo'ed back from the setWLSEnv.sh file - by using export CLASSPATH=$CLASSPATH:<<paste of echo'ed classpath from setWLSEnv.sh>> and then the same for the path. After this, I tried the java weblogic.version and that worked - so now, I guess I am left to deal with issue of my setWLSEnv.sh not setting the CLASSPATH and PATH variables.
    Thanks,
    Connie

  • Downgrading my wii from 4.3 to 4.1 assistance

    Hi, i was wondering if you guys would assist me with downgrading my wii from version 4.3u to 4.1u. It seems i accidently installed the latest update without any real knowledge of the problem it seemed to cause. See im trying to install the Homebrew channal, apparently you can not if you have version 4.3 and there is a way to downgrade back to 4.1 on a youtube vid and i just cant seem to figure this out... So i was wondering if you guys could possibly help me or if i could possibly trade my perfectly working Wii for another similar wii without the 4.3 update. Please respond

    Laura n David - It sounds like the OP already googled, as they found a YouTube video about it.
    Leetsauce - You may want to post this over in the "Gaming, Gadgets, and eReaders" section, rather than here in the "Policies" section. You're much more likely to get a fellow gamer to see it over there. I will try and have a moderator move it for you.

    How can I downgrade to version 5? If that is the only option available.

    Thanks for the reply. It doesn't have to process the php, it just has to show the HTML content. It did that just fine before the last upgrade but won't now.
    I've seen that page you referenced: http://kb.mozillazine.org/File_types_and_download_actions.
    It doesn't help. The things it says to look for aren't there for me, specifically:
    browser.download.pluginOverrideTypes
    plugin.disable_full_page_plugin_for_types
    I followed the rest of the instructions but it didn't help.
    I did get it to quit opening tabs, instead it prompts me what it should do with the file every time now. What it should do, and used to do, is open the php page and display the HTML content.
    Any other ideas?

  • Upgrade weblogic version to 10.x

    Hi,
    I have application developed using JDK1.4.2 and running in weblogic v7.x. If I were to upgrade to weblogic version 10.x, will I have face problem in terms of JDK compatilibility? Anyone has such experience?

    Well, with a few tweaks you should manage to get it running. We had to migrate an ear which was initially developed for OAS 10gR2 (Java 1.4) to WebLogic 10.3. It took as some time
    but we managed to do it in the end. Probably from weblogic to weblogic, the migration should be even easier.
    I think in the beginning WebLogic 10.3 was accepting the ear compiled by javac 1.4, though later we switched to 1.6 for obvious reasons.

    Hi,
    Since the Discovery system is an appliance - bundled hardware + software + content, it is not possible to upgrade from v2 to v3.0.             
    You are free to upgrade your v2.0 system's SAP components by  downloading patches and service packs from the SAP Service MarketPlace and  applying them to the V2 system  if your main intention is to patch the V2 to a higher software release.                                                
    The only way to get the Discovery system V3 is to purchase it from one of the vendors and would include hardware , software and content.                                 
    Please check the SDN pages for how to order a new system:

    On my new Imac I saved some files on the free trial version of Pages, since downloading the full version from Apple, have been unable to save or print from old files saved when using the trial version. Any ideas? Thank you!

    My guess is the 30-day trial period has expired but you didn't remove the trial before installing the full version. The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user.
    Yvan Koenig has written an AppleScript that removes the files. You can find it on his iDisk in For_iWork > iWork '09 > uninstall iWork '09.zip.
