A fastener and associated lock washer having an integral anti-rotation mechanism. The head of the fastener includes a plurality of saw teeth&#x2014;arranged in a radial array. A lock washer is configured to interact with the head of the fastener. The lock washer includes one or more spring tabs positioned to bear against the radial array of saw teeth. As the fastener is rotated in a first direction, the saw teeth depress and pass over the spring tab(s). However, if the user attempts to rotate the fastener in the opposite direction, the spring tab snaps up into the saw teeth and arrests the motion&#x2014;in the manner of a ratchet and pawl mechanism. The invention preferably includes a second means for selectively defeating the anti-rotation mechanism.

Fastener with unidirectional latch

A system and method is provided for initiating batch processing on a computer system from a terminal. The method generates a message from the terminal, where the message defines a transaction to be performed on a computer system. The transaction schedules and runs a program that extracts data from the message. The message is then transmitted to the computer system. The data is then used to generate batch job control language and a batch job is run on the computer system. The output of the batch job is then routed back to the terminal.

Transaction-initiated batch processing

A transfer of control to a batch application is intercepted, wherein a batch front-end routine receives control in place of the batch application and performs initialization processing. This initialization processing comprises issuing a DLI restart call and issuing a DLI checkpoint call. If the DLI restart call returns a checkpoint ID, then one or more databases associated with the batch application are repositioned. The transfer of control to the batch application is then resumed, whereby the batch application restarts from the checkpoint ID, if the checkpoint ID was returned by the DLI restart call, in a manner transparent to the batch application.

Auto-restart processing in an IMS batch application

A method and system for autonomic Information Management System (IMS) mainframe database pointer error diagnostic data extraction. A receiving module may receive a database name and an error detection time. An error detection module may locate database pointer errors on the failed IMS database. A list module may generate an Image Copy (IC) list corresponding to the failed database. A code generation module may generate Job Control Language (JCL) code for the selected entries in the IC list. An execution module executes the JCL code which operates a pointer checker utility on each clean IC. A log list module locates log data sets recorded in the time between the error and when the error was detected and an extraction module extracts an evaluation log list which comprises evaluation log data sets.

An apparatus and system are disclosed for performing semi-automatic dataset maintenance. The apparatus includes an input module that receives a dataset qualifier. The dataset qualifier describes a collection of datasets. The input module also receives a desired maintenance action to be applied to the datasets. A retrieval module retrieves a set of dataset identifiers that satisfy the dataset qualifier from a mainframe operating system. A command module constructs a set of mainframe operating system commands to fulfill the desired maintenance action. The set of commands includes at least one command for each dataset.

An apparatus, system, and method are disclosed for modular distribution and maintenance of non-'object code only' (OCO) dynamic components. OCO components comprise compiled executable modules. Non-OCO components comprise user readable and/or editable components. The modular distribution of non-OCO components comprises updating a skeleton data set comprising text and component fields such that user customizations and developer customizations are preserved. The modular distribution further allows for the generation of an output data in response to a reportable operational event, wherein the output data set is based on the skeleton data set and user customizations and developer customizations stored in customization data sets.

An apparatus and system are disclosed for analyzing computer events recorded in a plurality of computer datasets. The apparatus includes a read module configured to access chronicle records in two datasets, an extraction module configured to extract a timestamp from each chronicle record, a generation module configured to generate a chronicle time indicator for each chronicle record based on the extracted timestamp, and a placement module configured to place the generated chronicle time indicator into the associated chronicle record. Typically, chronicle records in a first chronicle record have records with desired timestamp characteristics while chronicle records in a second dataset have chronicle records with incompatible timestamp characteristics. The apparatus and method generate the chronicle time indicator to be compatible with desired timestamp characteristics of the first dataset and place the generated chronicle time indicator in each incompatible chronicle record.

Restarting failed IMS auto-restart batch applications

A DLI call from the batch application is intercepted, wherein the DLI call is made for the purpose of accessing a hierarchical database. It is then determined if the access to the hierarchical database is a checkpoint trigger event. A segment counter for a trigger segment in a checkpoint trigger for the checkpoint trigger event is incremented if the trigger segment is identified by the DLI call. The segment counter is compared to a segment commit threshold in the checkpoint trigger and commit point processing is performed on behalf of the batch application if the segment counter is in a predetermined relation to the segment commit threshold.

Auto-commit processing in an IMS batch application

An apparatus, system, and method are disclosed for scanning a partitioned data set ('PDS'). A receive module is included to receive a search criteria comprising one or more expressions. A member module is included to determine a set of PDS members to search based on the search criteria. A scan module is included to scan a record contained within each member of the set of PDS members. A determination module is included to determine whether a record satisfies the search criteria, where the search criteria comprises at least one expression that identifies a record that lacks a specified character string of the at least one expression. A return module is included to return the determined record. Each record in the scanned PDS has any length within a range supported by an operating system maintaining the scanned PDS.

The present invention increases the efficiency of dynamically, reusable computer environments by first retrieving data set information from a volume table of contents (VTOC) to ensure its consistency with the catalog. After obtaining the necessary information about the data sets, control statements are generated and appropriate programs invoked to perform the desired maintenance operations. Reinitializing and reconfiguring the reusable computer environment by starting with the VTOC prevents post-maintenance issues such as a data set with an entry in an integrated catalog facility (ICF) catalog while the data set no longer exists on a volume, a cataloged virtual storage access method (VSAM) cluster with disassociated DATA or INDEX data sets, and a data set catalog entry that has been scratched while the data set still exists on a volume. The present invention saves time and money by preventing such problems up-front instead of correcting them after-the-fact.

Apparatus, system, and method for automating VTOC driven data set maintenance

A user command communicating at least one log record search key is received from a user. A first set of one or more log records matching the log record search key is retrieved. Utilizing one or more fields from these log records, additional search criteria is dynamically composed. A second set of one or more log records matching the additional search criteria is retrieved from the DBMS log file wherein this second set of log records is logically related to the first set of log records and wherein the second set of log records is void of the log record search key. A log retrieval routine or tool deploying the above method is hereinafter referred to as a 'self-learning log retrieval tool'.

Task oriented log retrieval utilizing a self-learning search tool

A method is disclosed for condensing reported checkpoint log data that facilitates analysis of the checkpoint log data by minimizing extraneous results presented to a user. The method includes a user interface to receive a query expression from a user based on one or more conditions and one or more parameters. A record handler retrieves a checkpoint log record from a storage device. A structuring module parses the checkpoint log record into log entries. A comparison module applies the query expression to each log entry. This application of the query expression may include applying the query expression to a particular portion of the log entry specified by an offset. The output module generates a condensed checkpoint log record including log entries that satisfy the query expression.
