On this webpage, you have to create a new account. This account will help you in participating in the 2021 contest. You will get an IP address to connect to your Mainframe. Plus, you will get a username and password as well.
There is literally no difference between the two. Both will give you access to the same system. The IP address will be the same as well because it is the same mainframe that you are connecting to. Only the registration process is different. That is because only students are eligible to win prizes. So students have to register separately. All non-students can register and solve the same contest, but they will not be awarded any prizes for this contest.
MVS Turnkey is a ready-to-run Mainframe system for your Personal Computer. It has an older operating system called MVS 3.8j. Also, no installation is required for this system. So, you can just download the system and run it directly, no installation is required. The system can be downloaded from the below link:
Hercules Emulator can emulate z/Architecture on your Personal Computer. It can also emulate older architecture such as s/370 or s/390. The Emulator can also run z/OS using ADCD files from IBM. MVS Turnkey system uses this emulator only to run MVS 3.8j. You can download this software from the below link:
Relying on just usernames and passwords to secure your online accounts is no longer considered safe. Data breaches occur daily and hackers are always inventing new ways to take over your accounts. Protect yourself by enabling two-factor authentication (2FA). This blocks anyone using your stolen data by verifying your identity through your device. Enable 2FA now to protect your accounts online.

NOTE: The IBM Informix SDK limits passwords used for authenticating against the ODBC service on Unity Connection to 18 characters. There is nothing Cisco can do on the server or client side to get around this. Here's a link to anIBM document on this.
It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.
The PGP signatures can be verified using PGP or GPG. First download the Apache Derby KEYS as well as the asc signature file for the particular distribution. It is important that you get these files from the ultimate trusted source - the main ASF distribution site, rather than from a mirror. Then verify the signatures using ...
Generally, a download manager enables downloading of large files or multiples files in one session. Many web browsers, such as Internet Explorer 9, include a download manager. Stand-alone download managers also are available, including the Microsoft Download Manager.
The Microsoft Download Manager solves these potential problems. It gives you the ability to download multiple files at one time and download large files quickly and reliably. It also allows you to suspend active downloads and resume downloads that have failed.
On distributed platforms, you do need not to install any Db2 ODBC client driver for connectivity. ibm_db itself downloads and installs an odbc/cli driver from IBM website during installation. Just install ibm_db and it is ready for use.
npm install ibm_db internally downloads and install platform specific clidriver of recent release from here.To avoid this download, you can manually download clidriver from this location or install any verison of IBM Data Server Driver Package or Db2 Client or Sever in your system and point the install directory using IBM_DB_HOME environment variable. If IBM_DB_HOME or IBM_DB_INSTALLER_URL is set, npm install ibm_db do not download clidriver.
ibm_db works with all supported versions of Db2 Client and Server. Instead of using open source driver specific clidriver for ibm_db, you may download and install DSDRIVER or DB2Client from IBM Fix Central or IBM Passport Advantage of Db2 V18.104.22.168 onwards.
Although a small and dedicated community remains faithful to OS/2, OS/2 failed to catch on in the mass market and is little used outside certain niches where IBM traditionally had a stronghold. For example, many bank installations, especially automated teller machines, run OS/2 with a customized user interface; French SNCF national railways used OS/2 1.x in thousands of ticket selling machines. Telecom companies such as Nortel used OS/2 in some voicemail systems. Also, OS/2 was used for the host PC used to control the Satellite Operations Support System equipment installed at NPR member stations from 1994 to 2007, and used to receive the network's programming via satellite.
OS/2 has few native computer viruses; while it is not invulnerable by design, its reduced market share appears to have discouraged virus writers. There are, however, OS/2-based antivirus programs, dealing with DOS viruses and Windows viruses that could pass through an OS/2 server.
OS/2 was used as part of the Satellite Operations Support System (SOSS) for NPR's Public Radio Satellite System. SOSS was a computer-controlled system using OS/2 that NPR member stations used to receive programming feeds via satellite. SOSS was introduced in 1994 using OS/2 3.0, and was retired in 2007, when NPR switched over to its successor, the ContentDepot.
The sklearn.datasets.fetch_20newsgroups function is a datafetching / caching functions that downloads the data archive fromthe original 20 newsgroups website, extracts the archive contentsin the ~/scikit_learn_data/20news_home folder and calls thesklearn.datasets.load_files on either the training ortesting set folder, or both of them:
First-time users are encouraged to first download and install the Standard Edition and conduct tests to confirm that the software is compatible with their hardware and operating system. Technical questions regarding the use of the software should be directed to firstname.lastname@example.org. Brief questions (involving less than 10 minutes of time) will be answered as quickly as possible. A consultancy service is available for those who have more lengthy enquiries. Consultancy fees will be provided on request.
If it is an older Connect Server, click Download Aspera Connect to go to the Aspera Connect download page ( ), and download the Aspera Connect for the version of your operating system. When downloaded, locate and double-click the installer, and follow the instructions to complete the installation process.
By default, Connect downloads the files to the current user's desktop. To change that, in the Connect preferences window (Menu bar > Aspera Connect > Preferences), go to the Transfers preferences option, and set the download rule under the Downloads section:
The content protection is a feature that allows the uploaded files be encrypted during a transfer, to protect them while stored on the remote server. The uploader sets a password while uploading the file, and the password is required to decrypt the protected file.
The utility allows you to configure kdump as well as to enable or disable starting the service at boot time. When you are done, click Apply to save the changes. Unless you are already authenticated, enter the superuser password. The utility presents you with a reminder that you must reboot the system in order to apply any changes you have made to the configuration.

Spark SQL can convert an RDD of Row objects to a DataFrame, inferring the datatypes. Rows are constructed by passing a list ofkey/value pairs as kwargs to the Row class. The keys of this list define the column names of the table,and the types are inferred by sampling the whole dataset, similar to the inference that is performed on JSON files.
You can also manually specify the data source that will be used along with any extra optionsthat you would like to pass to the data source. Data sources are specified by their fully qualifiedname (i.e., org.apache.spark.sql.parquet), but for built-in sources you can also use their shortnames (json, parquet, jdbc, orc, libsvm, csv, text). DataFrames loaded from any datasource type can be converted into other types using this syntax.
By passing path/to/table to either SparkSession.read.parquet or SparkSession.read.load, Spark SQLwill automatically extract the partitioning information from the paths.Now the schema of the returned DataFrame becomes:
Starting from Spark 1.6.0, partition discovery only finds partitions under the given pathsby default. For the above example, if users pass path/to/table/gender=male to eitherSparkSession.read.parquet or SparkSession.read.load, gender will not be considered as apartitioning column. If users need to specify the base path that partition discoveryshould start with, they can set basePath in the data source options. For example,when path/to/table/gender=male is the path of the data andusers set basePath to path/to/table/, gender will be a partitioning column.
Tables from the remote database can be loaded as a DataFrame or Spark SQL temporary view usingthe Data Sources API. Users can specify the JDBC connection properties in the data source options.user and password are normally provided as connection properties forlogging into the data sources. In addition to the connection properties, Spark also supportsthe following case-sensitive options:
Beeline will ask you for a username and password. In non-secure mode, simply enter the username onyour machine and a blank password. For secure mode, please follow the instructions given in thebeeline documentation.
Prior to Spark 1.3 there were separate Java compatible classes (JavaSQLContext and JavaSchemaRDD)that mirrored the Scala API. In Spark 1.3 the Java API and Scala API have been unified. Usersof either language should use SQLContext and DataFrame. In general theses classes try touse types that are usable from both languages (i.e. Array instead of language specific collections).In some cases where no common type exists (e.g., for passing in closures or Maps) function overloadingis used instead. 2b1af7f3a8
