  • Using VB6 to search for existence of DataFile in Outlook

    - by Graeme
    Hi, I am wanting to write an Add-In for Outlook 2003 which, when Outlook is opened, search for the existence of a datafile called DMSDataStore and if it doesn't exist will install the datafile. I have managed to create the Add-In using VB6 and it runs when I open Outlook. However I haven't found the best/easiest way to search for the existence of the datafile. If the datafile exists it is visible within Outlook under the user's mailbox, much the same as an archive folder is. I would like to be able to search for it by name which is DMSDataFile. I did try - Set tmpInbox = parentFolder.Folders("DMSDataFile") This works OK if the datafile exists but will throw an error if it doesn't. I can create an error handler which will then install the datafile but this doesn't seem like a very tidy way of doing things. I guess I might have to recursively search for the datafile. Can someone let me know what is the best / easiest way to search for the datafile using the name of the datafile and give me some code with which to do it. Thanks G

  • Online DATAFILE MOVE in Oracle Database 12c

    - by Ulrike Schwinn (DBA Community)
    Einige Operationen im Datenbankumfeld können nicht nur offline sondern auch online durchgeführt werden. Ein wichtiges Kennzeichen einer Online Operation ist dabei, dass Abfragen und DML Operationen während des Ablaufs der Operation (beispielsweise einer Reorganisation) ohne Unterbrechung weiter laufen können. Je nach einplanbarer Maintenance Zeit ist es daher durchaus wünschenswert, gewisse Operationen online durchzuführen. Generell gibt es in jedem Datenbankrelease einige Erweiterungen im Umfeld von Online Operationen. Besonders im aktuellen Release 12c gibt es eine Vielzahl neuer Operationen zu diesem Thema.Während der ersten 12c Veranstaltungen fand besonders das Kommando "DATAFILE ONLINE MOVE" besondere Aufmerksamkeit bei vielen Kunden. Aus diesem Grund wird im aktuellen Tipp dazu eine kleine Einführung gegeben.  Mehr dazu erfahren Sie hier.

  • Transient mysqlcheck errors about "size of datafile" (file too small)

    - by Adam Backstrom
    Running mysqlcheck on a live database is giving me transient errors like this one: mydatabase.mytable error : Size of datafile is: 500719688 Should be: 501000484 error : Corrupt When I run the command again or check the table one-off using mysql, it's listed as OK. Is this just a side effect of running checks on live tables? Is it possible that data is not flushed, hence the strange discrepancy? We moved several databases this morning by shutting down mysqld on the source and rsyncing files across to the new server, but these are all MyISAM tables so I don't believe the two things are related. (But I mention it just in case.)

  • Map element position in data file to class property

    - by Augusto
    I need to read/write files, following a format provided by a third party specification. The specification itself is pretty simple: it says the position and the size of the data that will be saved in the file. For example: Position Size Description -------------------------------------------------- 0001 10 Device serial number 0011 02 Hour 0013 02 Minute 0015 02 Second 0017 02 Day 0019 02 Month 0021 02 Year The list is very long, it has about 400 elements. But lots of them can be combined. For example, hour, minute, second, day, month and year can be combined in a single DateTime object. I've splitted the elements into about 4 categories, and created separeted classes for holding the data. So, instead of a big structure representing the data, I have some smaller classes. I've also created different classes for reading and writing the data. The problem is: how to map the positions in the file to the objects properties, so that I don't need to repeat the values in the reading/writing class? I could use some custom attributes and retrieve them via reflection. But since the code will be running on devices with small memory and processor, it would be nice to find another way. My current read code looks like this: public void Read() { DataFile dataFile = new DataFile(); // the arguments are: position, size dataFile.SerialNumber = ReadLong(1, 10); //... } Any ideas on this one? Thanks!

  • Efficient way to organise data file in columns with Python

    I'm getting an output data file of a program which looks like this, with more than one line for each time step: 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 7.9819E-06 1.7724E-02 2.3383E-02 3.0048E-02 3.8603E-02 4.9581E-02 5.6635E-02 4.9991E-02 3.9052E-02 3.0399E-02 .... I want to arrange it in ten columns I have made a Python script, using regular expressions to delete \n in the proper lines, but I think that there should be a simpler more elegant way to do it, here is my script: import re with open('inputfile', encoding='utf-8') as file1: datai=file1.read() dataf=re.sub(r'(?P<nomb>( \d\.\d\d\d\dE.\d\d){8})\n','\g<nomb>',datai) with open('result.txt',mode='w',encoding='utf-8') as resultfile: resultfile.write(datof) Thanks in advance

  • How to handle ordering of @Rule's when they are dependant on eachother

    - by Lennart Schedin
    I use embedded servers that run inside Junit test cases. Sometimes these servers require a working directory (for example the Apache Directory server). The new @Rule in Junit 4.7 can handle these cases. The TemporaryFolder-Rule can create a temporary directory. A custom ExternalResource-Rule can be created for server. But how do I handle if I want to pass the result from one rule into another: import static org.junit.Assert.assertEquals; import java.io.*; import org.junit.*; import org.junit.rules.*; public class FolderRuleOrderingTest { @Rule public TemporaryFolder folder = new TemporaryFolder(); @Rule public MyNumberServer server = new MyNumberServer(folder); @Test public void testMyNumberServer() throws IOException { server.storeNumber(10); assertEquals(10, server.getNumber()); } /** Simple server that can store one number */ private static class MyNumberServer extends ExternalResource { private TemporaryFolder folder; /** The actual datafile where the number are stored */ private File dataFile; public MyNumberServer(TemporaryFolder folder) { this.folder = folder; } @Override protected void before() throws Throwable { if (folder.getRoot() == null) { throw new RuntimeException("TemporaryFolder not properly initialized"); } //All server data are stored to a working folder File workingFolder = folder.newFolder("my-work-folder"); dataFile = new File(workingFolder, "datafile"); } public void storeNumber(int number) throws IOException { dataFile.createNewFile(); DataOutputStream out = new DataOutputStream(new FileOutputStream(dataFile)); out.writeInt(number); } public int getNumber() throws IOException { DataInputStream in = new DataInputStream(new FileInputStream(dataFile)); return in.readInt(); } } } In this code the folder is sent as a parameter into the server so that the server can create a working directory to store data. However this does not work because Junit processes the rules in reverse order as they are defined in the file. The TemporaryFolder Rule will not be executed before the server Rule. Thus the root-folder in TempraryFolder will be null, resulting that any files are created relative to the current working directory. If I reverse the order of the attributes in my class I get a compile error because I cannot reference a variable before it is defined. I'm using Junit 4.8.1 (because the ordering of rules was fixed a bit from the 4.7 release)

  • 11gr2 DataGuard: Restarting DUPLICATE After a Failure

    - by rene.kundersma
    One of the great new features that comes in very handy when databases get larger and larger these days is RMAN's capability to duplicate from an active database and even restart a duplicate when it fails. Imagine yourself the problem I had lately; I used the duplicate from active database feature and had to wait for an hour or 6 before all datafiles where transferred.At the end of the process some error occurred because of the syntax. While this error was easily to solve I was afraid I had to redo the complete procedure and transfer the 2.5 TB again. Well, 11gr2 RMAN surprised when I re-ran my command with the following output: Using previous duplicated file +DATA/fin2prod/datafile/users.2968.719237649 for datafile 12 with checkpoint SCN of 183289288148 Using previous duplicated file +DATA/fin2prod/datafile/users.2703.719237975 for datafile 13 with checkpoint SCN of 183289295823 Above I only show a small snippet, but what happend is that RMAN smartly skipped all files that where already transferred ! The documentation says this: RMAN automatically optimizes a DUPLICATE command that is a repeat of a previously failed DUPLICATE command. The repeat DUPLICATE command notices which datafiles were successfully copied earlier and does not copy them again. This applies to all forms of duplication, whether they are backup-based (with and without a target connection) or active database duplication. The automatic optimization of the DUPLICATE command can be especially useful when a failure occurs during the duplication of very large databases. If a DUPLICATE operation fails, you need only run the DUPLICATE again, using the same parameters contained in the original DUPLICATE command. Please see chapter 23 of the 11g Release 2 Database Backup and Recovery User's Guide for more details. B.w.t. be very careful with the duplicate command. A small mistake in one of the 'convert' parameters can potentially overwrite your target's controlfile without prompting ! Rene Kundersma Technical Architect Oracle Technology Services

  • Internationalize WebCenter Portal - Content Presenter

    - by Stefan Krantz
    Lately we have been involved in engagements where internationalization has been holding the project back from success. In this post we are going to explain how to get Content Presenter and its editorials to comply with the current selected locale for the WebCenter Portal session. As you probably know by now WebCenter Portal leverages the Localization support from Java Server Faces (JSF), in this post we will assume that the localization is controlled and enforced by switching the current browsers locale between English and Spanish. There is two main scenarios in internationalization of a content enabled pages, since Content Presenter offers both presentation of information as well as contribution of information, in this post we will look at how to enable seamless integration of correct localized version of the back end content file and how to enable the editor/author to edit the correct localized version of the file based on the current browser locale. Solution Scenario 1 - Localization aware content presentation Due to the amount of steps required to implement the enclosed solution proposal I have decided to share the solution with you in group components for each facet of the solution. If you want to get more details on each step, you can review the enclosed components. This post will guide you through the steps of enabling each component and what it enables/changes in each section of the system. Enable Content Presenter Customization By leveraging a predictable naming convention of the data files used to hold the content for the Content Presenter instance we can easily develop a component that will dynamically switch the name out before presenting the information. The naming convention we have leverage is the industry best practice by having a shared identifier as prefix (ContentABC) and a language enabled suffix (_EN) (_ES). So the assumption is that each file pair in above example should look like following:- English version - (ContentABC_EN)- Spanish version - (ContentABC_ES) Based on above theory we can now easily regardless of the primary version assigned to the content presenter instance switch the language out by using the localization support from JSF. Below java bean (oracle.webcenter.doclib.internal.view.presenter.NLSHelperBean) is enclosed in the customization project available for download at the bottom of the post: 1: public static final String CP_D_DOCNAME_FORMAT = "%s_%s"; 2: public static final int CP_UNIQUE_ID_INDEX = 0; 3: private ContentPresenter presenter = null; 4:   5:   6: public NLSHelperBean() { 7: super(); 8: } 9:   10: /** 11: * This method updates the configuration for the pageFlowScope to have the correct datafile 12: * for the current Locale 13: */ 14: public void initLocaleForDataFile() { 15: String dataFile = null; 16: // Checking that state of presenter is present, also make sure the item is eligible for localization by locating the "_" in the name 17: if(presenter.getConfiguration().getDatasource() != null && 18: presenter.getConfiguration().getDatasource().isNodeDatasource() && 19: presenter.getConfiguration().getDatasource().getNodeIdDatasource() != null && 20: !presenter.getConfiguration().getDatasource().getNodeIdDatasource().equals("") && 21: presenter.getConfiguration().getDatasource().getNodeIdDatasource().indexOf("_") > 0) { 22: dataFile = presenter.getConfiguration().getDatasource().getNodeIdDatasource(); 23: FacesContext fc = FacesContext.getCurrentInstance(); 24: //Leveraging the current faces contenxt to get current localization language 25: String currentLocale = fc.getViewRoot().getLocale().getLanguage().toUpperCase(); 26: String newDataFile = dataFile; 27: String [] uniqueIdArr = dataFile.split("_"); 28: if(uniqueIdArr.length > 0) { 29: newDataFile = String.format(CP_D_DOCNAME_FORMAT, uniqueIdArr[CP_UNIQUE_ID_INDEX], currentLocale); 30: } 31: //Replacing the current Node datasource with localized datafile. 32: presenter.getConfiguration().getDatasource().setNodeIdDatasource(newDataFile); 33: } 34: } With this bean code available to our WebCenter Portal implementation we can start the next step, by overriding the standard behavior in content presenter by applying a MDS Taskflow customization to the content presenter taskflow, following taskflow customization has been applied to the customization project attached to this post:- Library: WebCenter Document Library Service View- Path: oracle.webcenter.doclib.view.jsf.taskflows.presenter- File: contentPresenter.xml Changes made in above customization view:1. A new method invocation activity has been added (initLocaleForDataFile)2. The method invocation invokes the new NLSHelperBean3. The default activity is moved to the new Method invocation (initLocaleForDataFile)4. The outcome from the method invocation goes to determine-navigation (original default activity) The above changes concludes the presentation modification to support a compatible localization scenario for a content driven page. In addition this customization do not limit or disables the out of the box capabilities of WebCenter Portal. Steps to enable above customization Start JDeveloper and open your WebCenter Portal Application Select "Open Project" and include the extracted project you downloaded (CPNLSCustomizations.zip) Make sure the build out put from CPNLSCustomizations project is a dependency to your Portal project Deploy your Portal Application to your WC_CustomPortal managed server Make sure your naming convention of the two data files follow above recommendation Example result of the solution: Solution Scenario 2 - Localization aware content creation and authoring As you could see from Solution Scenario 1 we require the naming convention to be strictly followed, this means in the hands of a user with limited technology knowledge this can be one of the failing links in this solutions. Therefore I strongly recommend that you also follow this part since this will eliminate this risk and also increase the editors/authors usability with a magnitude. The current WebCenter Portal Architecture leverages WebCenter Content today to maintain, publish and manage content, therefore we need to make few efforts in making sure this part of the architecture is on board with our new naming practice and also simplifies the creation of content for our end users. As you probably remember the naming convention required a prefix to be common so I propose we enable a new component that help you auto name the content items dDocName (this means that the readable title can still be in a human readable format). The new component (WCP-LocalizationSupport.zip) built for this scenario will enable a couple of things: 1. A new service where a sequential number can be generate on request - service name: GET_WCP_LOCALE_CONTENTID 2. The content presenter is leveraging a specific function when launching the content creation wizard from within Content Presenter. Assumption is that users will create the content by clicking "Create Web Content" button.

  • New hidden parameters in Oracle 11.2

    - by Mike Dietrich
    We really welcome every external review of our slides. And also recommendations from customers visiting our workshops. So it happened to me more than a week ago that Marco Patzwahl, the owner of MuniqSoft GmbH, had a very lengthy train ride in Germany (as the engine drivers go on strike this week it could have become even worse) and nothing better to do then reviewing our slide set. And he had plenty of recommendations. Besides that he pointed us to something at least I was not aware of and added it to the slides: In patch set 11.2.0.2 a new behaviour for datafile write errors has been implemented. With this release ANY write error to a datafile will cause the instance to abort. Before 11.2.0.2 those errors usually led to an offline datafile if the database operates in archivelog mode (your production database do, don’t they?!) and the datafile does not belong to the SYSTEM tablespace. Internal discussion found this behaviour not up-to-date and alligned with RAC systems and modern storages. Therefore it has been changed and a new underscore parameter got introduced. _DATAFILE_WRITE_ERRORS_CRASH_INSTANCE=TRUE This is the default setting´and the new behaviour beginning with Oracle 11.2.0.2 If you would like to revert to the pre-11.2.0.2 behaviour you’ll have to set in your init.ora/spfile this parameter to false. But keep in mind that there’s a reason why this has been changed. You’ll find more info in MOS Note: 7691270.8 and this topic in the current version of the slides on slide 255. Thanks to Marco for the review!!   And then I received an email from Kurt Van Meerbeeck today. Kurt is pretty well known in the Oracle community. And he’s the owner of jDUL/DUDE, a database unloading tool which bypasses the Oracle database engine and access data direclty from the blocks. Kurt visited the upgrade workshop two weeks ago in Belgium and did highlight to me that since Oracle 11.2.0.1 even though you haven’t set neither SGA_TARGET nor MEMORY_TARGET the database might still do resize operations. Reason why this behaviour has been changed: Prevention of ORA-4031 errors. But on databases with extremly high loads this can cause trouble. Further information can be found in MOS Note:1269139.1 . And the parameter set to TRUE by default is called _MEMORY_IMM_MODE_WITHOUT_AUTOSGA=TRUE This can be found now in the slide set as well on slide number 240. And thanks to Kurt for this information!!

  • Partitioned Repository for WebCenter Content using Oracle Database 11g

    - by Adao Junior
    One of the biggest challenges for content management solutions is related to the storage management due the high volumes of the unstoppable growing of information. Even if you have storage appliances and a lot of terabytes, thinks like backup, compression, deduplication, storage relocation, encryption, availability could be a nightmare. One standard option that you have with the Oracle WebCenter Content is to store data to the database. And the Oracle Database allows you leverage features like compression, deduplication, encryption and seamless backup. But with a huge volume, the challenge is passed to the DBA to keep the WebCenter Content Database up and running. One solution is the use of DB partitions for your content repository, but what are the implications of this? Can I fit this with my business requirements? Well, yes. It’s up to you how you will manage that, you just need a good plan. During you “storage brainstorm plan” take in your mind what you need, such as storage petabytes of documents? You need everything on-line? There’s a way to logically separate the “good content” from the “legacy content”? The first thing that comes to my mind is to use the creation date of the document, but you need to remember that this document could receive a lot of revisions and maybe you can consider the revision creation date. Your plan can have also complex rules like per Document Type or per a custom metadata like department or an hybrid per date, per DocType and an specific virtual folder. Extrapolation the use, you can have your repository distributed in different servers, different disks, different disk types (Such as ssds, sas, sata, tape,…), separated accordingly your business requirements, separating the “hot” content from the legacy and easily matching your compliance requirements. If you think to use by revision, the simple way is to consider the dId, that is the sequential unique id for every content created using the WebCenter Content or the dLastModified that is the date field of the FileStorage table that contains the date of inclusion of the content to the DB Table using SecureFiles. Using the scenario of partitioned repository using an hierarchical separation by date, we will transform the FileStorage table in an partitioned table using  “Partition by Range” of the dLastModified column (You can use the dId or a join with other tables for other metadata such as dDocType, Security, etc…). The test scenario bellow covers: Previous existent data on the JDBC Storage to be migrated to the new partitioned JDBC Storage Partition by Date Automatically generation of new partitions based on a pre-defined interval (Available only with Oracle Database 11g+) Deduplication and Compression for legacy data Oracle WebCenter Content 11g PS5 (Could present some customizations that do not affect the test scenario) For the test case you need some data stored using JDBC Storage to be the “legacy” data. If you do not have done before, just create an Storage rule pointed to the JDBC Storage: Enable the metadata StorageRule in the UI and upload some documents using this rule. For this test case you can run using the schema owner or an dba user. We will use the schema owner TESTS_OCS. I can’t forgot to tell that this is just a test and you should do a proper backup of your environment. When you use the schema owner, you need some privileges, using the dba user grant the privileges needed: REM Grant privileges required for online redefinition. GRANT EXECUTE ON DBMS_REDEFINITION TO TESTS_OCS; GRANT ALTER ANY TABLE TO TESTS_OCS; GRANT DROP ANY TABLE TO TESTS_OCS; GRANT LOCK ANY TABLE TO TESTS_OCS; GRANT CREATE ANY TABLE TO TESTS_OCS; GRANT SELECT ANY TABLE TO TESTS_OCS; REM Privileges required to perform cloning of dependent objects. GRANT CREATE ANY TRIGGER TO TESTS_OCS; GRANT CREATE ANY INDEX TO TESTS_OCS; In our test scenario we will separate the content as Legacy, Day1, Day2, Day3 and Future. This last one will partitioned automatically using 3 tablespaces in a round robin mode. In a real scenario the partition rule could be per month, per year or any rule that you choose. Table spaces for the test scenario: CREATE TABLESPACE TESTS_OCS_PART_LEGACY DATAFILE 'tests_ocs_part_legacy.dat' SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_DAY1 DATAFILE 'tests_ocs_part_day1.dat' SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_DAY2 DATAFILE 'tests_ocs_part_day2.dat' SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_DAY3 DATAFILE 'tests_ocs_part_day3.dat' SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_ROUND_ROBIN_A 'tests_ocs_part_round_robin_a.dat' DATAFILE SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_ROUND_ROBIN_B 'tests_ocs_part_round_robin_b.dat' DATAFILE SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; CREATE TABLESPACE TESTS_OCS_PART_ROUND_ROBIN_C 'tests_ocs_part_round_robin_c.dat' DATAFILE SIZE 500K AUTOEXTEND ON NEXT 500K MAXSIZE UNLIMITED; Before start, gather optimizer statistics on the actual FileStorage table: EXEC DBMS_STATS.GATHER_TABLE_STATS(USER, 'FileStorage', cascade => TRUE); Now check if is possible execute the redefinition process: EXEC DBMS_REDEFINITION.CAN_REDEF_TABLE('TESTS_OCS', 'FileStorage',DBMS_REDEFINITION.CONS_USE_PK); If no errors messages, you are good to go. Create a Partitioned Interim FileStorage table. You need to create a new table with the partition information to act as an interim table: CREATE TABLE FILESTORAGE_Part ( DID NUMBER(*,0) NOT NULL ENABLE, DRENDITIONID VARCHAR2(30 CHAR) NOT NULL ENABLE, DLASTMODIFIED TIMESTAMP (6), DFILESIZE NUMBER(*,0), DISDELETED VARCHAR2(1 CHAR), BFILEDATA BLOB ) LOB (BFILEDATA) STORE AS SECUREFILE ( ENABLE STORAGE IN ROW NOCACHE LOGGING KEEP_DUPLICATES NOCOMPRESS ) PARTITION BY RANGE (DLASTMODIFIED) INTERVAL (NUMTODSINTERVAL(1,'DAY')) STORE IN (TESTS_OCS_PART_ROUND_ROBIN_A, TESTS_OCS_PART_ROUND_ROBIN_B, TESTS_OCS_PART_ROUND_ROBIN_C) ( PARTITION FILESTORAGE_PART_LEGACY VALUES LESS THAN (TO_DATE('05-APR-2012 12.00.00 AM', 'DD-MON-YYYY HH.MI.SS AM')) TABLESPACE TESTS_OCS_PART_LEGACY LOB (BFILEDATA) STORE AS SECUREFILE ( TABLESPACE TESTS_OCS_PART_LEGACY RETENTION NONE DEDUPLICATE COMPRESS HIGH ), PARTITION FILESTORAGE_PART_DAY1 VALUES LESS THAN (TO_DATE('06-APR-2012 07.25.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) TABLESPACE TESTS_OCS_PART_DAY1 LOB (BFILEDATA) STORE AS SECUREFILE ( TABLESPACE TESTS_OCS_PART_DAY1 RETENTION AUTO KEEP_DUPLICATES COMPRESS ), PARTITION FILESTORAGE_PART_DAY2 VALUES LESS THAN (TO_DATE('06-APR-2012 07.55.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) TABLESPACE TESTS_OCS_PART_DAY2 LOB (BFILEDATA) STORE AS SECUREFILE ( TABLESPACE TESTS_OCS_PART_DAY2 RETENTION AUTO KEEP_DUPLICATES NOCOMPRESS ), PARTITION FILESTORAGE_PART_DAY3 VALUES LESS THAN (TO_DATE('06-APR-2012 07.58.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) TABLESPACE TESTS_OCS_PART_DAY3 LOB (BFILEDATA) STORE AS SECUREFILE ( TABLESPACE TESTS_OCS_PART_DAY3 RETENTION AUTO KEEP_DUPLICATES NOCOMPRESS ) ); After the creation you should see your partitions defined. Note that only the fixed range partitions have been created, none of the interval partition have been created. Start the redefinition process: BEGIN DBMS_REDEFINITION.START_REDEF_TABLE( uname => 'TESTS_OCS' ,orig_table => 'FileStorage' ,int_table => 'FileStorage_PART' ,col_mapping => NULL ,options_flag => DBMS_REDEFINITION.CONS_USE_PK ); END; This operation can take some time to complete, depending how many contents that you have and on the size of the table. Using the DBA user you can check the progress with this command: SELECT * FROM v$sesstat WHERE sid = 1; Copy dependent objects: DECLARE redefinition_errors PLS_INTEGER := 0; BEGIN DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS( uname => 'TESTS_OCS' ,orig_table => 'FileStorage' ,int_table => 'FileStorage_PART' ,copy_indexes => DBMS_REDEFINITION.CONS_ORIG_PARAMS ,copy_triggers => TRUE ,copy_constraints => TRUE ,copy_privileges => TRUE ,ignore_errors => TRUE ,num_errors => redefinition_errors ,copy_statistics => FALSE ,copy_mvlog => FALSE ); IF (redefinition_errors > 0) THEN DBMS_OUTPUT.PUT_LINE('>>> FileStorage to FileStorage_PART temp copy Errors: ' || TO_CHAR(redefinition_errors)); END IF; END; With the DBA user, verify that there's no errors: SELECT object_name, base_table_name, ddl_txt FROM DBA_REDEFINITION_ERRORS; *Note that will show 2 lines related to the constrains, this is expected. Synchronize the interim table FileStorage_PART: BEGIN DBMS_REDEFINITION.SYNC_INTERIM_TABLE( uname => 'TESTS_OCS', orig_table => 'FileStorage', int_table => 'FileStorage_PART'); END; Gather statistics on the new table: EXEC DBMS_STATS.GATHER_TABLE_STATS(USER, 'FileStorage_PART', cascade => TRUE); Complete the redefinition: BEGIN DBMS_REDEFINITION.FINISH_REDEF_TABLE( uname => 'TESTS_OCS', orig_table => 'FileStorage', int_table => 'FileStorage_PART'); END; During the execution the FileStorage table is locked in exclusive mode until finish the operation. After the last command the FileStorage table is partitioned. If you have contents out of the range partition, you should see the new partitions created automatically, not generating an error if you “forgot” to create all the future ranges. You will see something like: You now can drop the FileStorage_PART table: border-bottom-width: 1px; border-bottom-style: solid; text-align: left; border-left-color: silver; border-left-width: 1px; border-left-style: solid; padding-bottom: 4px; line-height: 12pt; background-color: #f4f4f4; margin-top: 20px; margin-right: 0px; margin-bottom: 10px; margin-left: 0px; padding-left: 4px; width: 97.5%; padding-right: 4px; font-family: 'Courier New', Courier, monospace; direction: ltr; max-height: 200px; font-size: 8pt; overflow-x: auto; overflow-y: auto; border-top-color: silver; border-top-width: 1px; border-top-style: solid; cursor: text; border-right-color: silver; border-right-width: 1px; border-right-style: solid; padding-top: 4px; " id="codeSnippetWrapper"> DROP TABLE FileStorage_PART PURGE; To check the FileStorage table is valid and is partitioned, use the command: SELECT num_rows,partitioned FROM user_tables WHERE table_name = 'FILESTORAGE'; You can list the contents of the FileStorage table in a specific partition, per example: SELECT * FROM FileStorage PARTITION (FILESTORAGE_PART_LEGACY) Some useful commands that you can use to check the partitions, note that you need to run using a DBA user: SELECT * FROM DBA_TAB_PARTITIONS WHERE table_name = 'FILESTORAGE';   SELECT * FROM DBA_TABLESPACES WHERE tablespace_name like 'TESTS_OCS%'; After the redefinition process complete you have a new FileStorage table storing all content that has the Storage rule pointed to the JDBC Storage and partitioned using the rule set during the creation of the temporary interim FileStorage_PART table. At this point you can test the WebCenter Content downloading the documents (Original and Renditions). Note that the content could be already in the cache area, take a look in the weblayout directory to see if a file with the same id is there, then click on the web rendition of your test file and see if have created the file and you can open, this means that is all working. The redefinition process can be repeated many times, this allow you test what the better layout, over and over again. Now some interesting maintenance actions related to the partitions: Make an tablespace read only. No issues viewing, the WebCenter Content do not alter the revisions When try to delete an content that is part of an read only tablespace, an error will occurs and the document will not be deleted The only way to prevent errors today is creating an custom component that checks the partitions and if you have an document in an “Read Only” repository, execute the deletion process of the metadata and mark the document to be deleted on the next db maintenance, like a new redefinition. Take an tablespace off-line for archiving purposes or any other reason. When you try open an document that is included in this tablespace will receive an error that was unable to retrieve the content, but the others online tablespaces are not affected. Same behavior when deleting documents. Again, an custom component is the solution. If you have an document “out of range”, the component can show an message that the repository for that document is offline. This can be extended to a option to the user to request to put online again. Moving some legacy content to an offline repository (table) using the Exchange option to move the content from one partition to a empty nonpartitioned table like FileStorage_LEGACY. Note that this option will remove the registers from the FileStorage and will not be able to open the stored content. You always need to keep in mind the indexes and constrains. An redefinition separating the original content (vault) from the renditions and separate by date ate the same time. This could be an option for DAM environments that want to have an special place for the renditions and put the original files in a storage with less performance. The process will be the same, you just need to change the script of the interim table to use composite partitioning. Will be something like: CREATE TABLE FILESTORAGE_RenditionPart ( DID NUMBER(*,0) NOT NULL ENABLE, DRENDITIONID VARCHAR2(30 CHAR) NOT NULL ENABLE, DLASTMODIFIED TIMESTAMP (6), DFILESIZE NUMBER(*,0), DISDELETED VARCHAR2(1 CHAR), BFILEDATA BLOB ) LOB (BFILEDATA) STORE AS SECUREFILE ( ENABLE STORAGE IN ROW NOCACHE LOGGING KEEP_DUPLICATES NOCOMPRESS ) PARTITION BY LIST (DRENDITIONID) SUBPARTITION BY RANGE (DLASTMODIFIED) ( PARTITION Vault VALUES ('primaryFile') ( SUBPARTITION FILESTORAGE_VAULT_LEGACY VALUES LESS THAN (TO_DATE('05-APR-2012 12.00.00 AM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_VAULT_DAY1 VALUES LESS THAN (TO_DATE('06-APR-2012 07.25.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_VAULT_DAY2 VALUES LESS THAN (TO_DATE('06-APR-2012 07.55.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_VAULT_DAY3 VALUES LESS THAN (TO_DATE('06-APR-2012 07.58.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_VAULT_FUTURE VALUES LESS THAN (MAXVALUE) ) ,PARTITION WebLayout VALUES ('webViewableFile') ( SUBPARTITION FILESTORAGE_WEBLAYOUT_LEGACY VALUES LESS THAN (TO_DATE('05-APR-2012 12.00.00 AM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_WEBLAYOUT_DAY1 VALUES LESS THAN (TO_DATE('06-APR-2012 07.25.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_WEBLAYOUT_DAY2 VALUES LESS THAN (TO_DATE('06-APR-2012 07.55.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_WEBLAYOUT_DAY3 VALUES LESS THAN (TO_DATE('06-APR-2012 07.58.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_WEBLAYOUT_FUTURE VALUES LESS THAN (MAXVALUE) ) ,PARTITION Special VALUES ('Special') ( SUBPARTITION FILESTORAGE_SPECIAL_LEGACY VALUES LESS THAN (TO_DATE('05-APR-2012 12.00.00 AM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_SPECIAL_DAY1 VALUES LESS THAN (TO_DATE('06-APR-2012 07.25.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_SPECIAL_DAY2 VALUES LESS THAN (TO_DATE('06-APR-2012 07.55.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_SPECIAL_DAY3 VALUES LESS THAN (TO_DATE('06-APR-2012 07.58.00 PM', 'DD-MON-YYYY HH.MI.SS AM')) LOB (BFILEDATA) STORE AS SECUREFILE , SUBPARTITION FILESTORAGE_SPECIAL_FUTURE VALUES LESS THAN (MAXVALUE) ) )ENABLE ROW MOVEMENT; The next post related to partitioned repository will come with an sample component to handle the possible exceptions when you need to take off line an tablespace/partition or move to another place. Also, we can include some integration to the Retention Management and Records Management. Another subject related to partitioning is the ability to create an FileStore Provider pointed to a different database, raising the level of the distributed storage vs. performance. Let us know if this is important to you or you have an use case not listed, leave a comment. Cross-posted on the blog.ContentrA.com

    Hello (and thanks in advance) I'm in a bit of a quandry, I cant seem to figure out why I'm seg faulting.

  • Memory efficient import many data files into panda DataFrame in Python

    - by richardh
    I import into a panda DataFrame a directory of |-delimited.dat files. The following code works, but I eventually run out of RAM with a MemoryError:. import pandas as pd import glob temp = [] dataDir = 'C:/users/richard/research/data/edgar/masterfiles' for dataFile in glob.glob(dataDir + '/master_*.dat'): print dataFile temp.append(pd.read_table(dataFile, delimiter='|', header=0)) masterAll = pd.concat(temp) Is there a more memory efficient approach? Or should I go whole hog to a database? (I will move to a database eventually, but I am baby stepping my move to pandas.) Thanks! FWIW, here is the head of an example .dat file: cik|cname|ftype|date|fileloc 1000032|BINCH JAMES G|4|2011-03-08|edgar/data/1000032/0001181431-11-016512.txt 1000045|NICHOLAS FINANCIAL INC|10-Q|2011-02-11|edgar/data/1000045/0001193125-11-031933.txt 1000045|NICHOLAS FINANCIAL INC|8-K|2011-01-11|edgar/data/1000045/0001193125-11-005531.txt 1000045|NICHOLAS FINANCIAL INC|8-K|2011-01-27|edgar/data/1000045/0001193125-11-015631.txt 1000045|NICHOLAS FINANCIAL INC|SC 13G/A|2011-02-14|edgar/data/1000045/0000929638-11-00151.txt

  • Are fopen/fread/fgets PID-safe in C ?

    - by Jane
    Various users are browsing through a website 100% programmed in C (CGI). Each webpage uses fopen/fgets/fread to read common data (like navigation bars) from files. Would each call to fopen/fgets/fread interefere with each other if various people are browsing the same page ? If so, how can this be solved in C ? (This is a Linux server, compiling is done with gcc and this is for a CGI website programmed in C.) Example: FILE *DATAFILE = fopen(PATH, "r"); if ( DATAFILE != NULL ) { while ( fgets( LINE, BUFFER, DATAFILE ) ) { /* do something */ } }

  • Passing arguments to an Rspec SpecTask

    - by Bayard Randel
    Rake allows for the following syntax: task :my_task, :arg1, :arg2 do |t, args| puts "Args were: #{args}" end I'd like to be able to do the same, but with RSpecs SpecTask. The following unfortunately fails: desc "Run example with argument" SpecTask.new('my_task'), :datafile do |t, args| t.spec_files = FileList['cvd*_spec.rb -datafile=#{args}'] t.spec_opts = ["-c -f specdoc"] end Is it possible to achieve this with a SpecTask, or is there an alternative approach?
