How does iCheck work technically?

iCheck operates through batch jobs submitted to the z/OS operating system. Users interact with the tool by defining control cards that specify the databases to be checked and the types of errors to be reported. The tool then generates reports detailing the identified issues.

How is iCheck configured?

Configuration is primarily managed through control cards. These cards specify parameters such as the database names, error types to check, and output report formats. There are no graphical interfaces; all configuration is done through JCL.

What kind of output does iCheck produce?

iCheck generates reports in a format suitable for printing or viewing on a mainframe console. The reports detail the errors found, including the database name, block number, segment type, and error description. These reports are essential for diagnosing and resolving database issues.

What is the business value of using iCheck?

By identifying and reporting database errors, iCheck helps prevent data corruption, which can lead to application downtime and data loss. This proactive approach reduces the risk of costly recovery efforts and ensures data reliability.

How does iCheck improve operational efficiency?

iCheck improves the efficiency of database maintenance by automating the error-detection process. This automation reduces the time and effort required to identify and resolve database issues, allowing database administrators to focus on other critical tasks.

How does iCheck contribute to data quality?

The tool contributes to improved data quality by ensuring that IMS databases are free from errors and inconsistencies. This leads to more reliable application performance and better decision-making based on accurate data.

How does iCheck reduce operational costs?

By proactively identifying and addressing database errors, iCheck helps to minimize the risk of application outages and data loss. This contributes to a more stable and reliable IT environment, reducing the overall cost of operations.

What security features does iCheck offer?

iCheck does not have built-in security features such as authentication or access control. Security is managed at the z/OS level through RACF or similar security products. Access to the datasets and JCL used by iCheck is controlled through these systems.

How is access to iCheck controlled?

The tool relies on the security measures implemented on the z/OS platform. User access to the JCL and datasets used by iCheck is managed through security products like RACF, which provides role-based access control.

Does iCheck encrypt data?

iCheck does not encrypt data. Data security is handled by the underlying IMS database and the z/OS operating system. Sensitive data within the IMS databases should be protected using the security features provided by these systems.

What audit capabilities are available?

Auditing is primarily handled through z/OS system logs and any auditing features provided by the IMS database. iCheck itself does not provide specific audit logging capabilities. Administrators should monitor system logs for any unauthorized access attempts.

How is iCheck operated?

iCheck is executed as a batch job on z/OS. The job control language (JCL) defines the parameters for the database analysis. The JCL specifies the input datasets, the databases to be checked, and the output report destinations.

How is iCheck monitored?

Monitoring is primarily done by reviewing the output reports generated by iCheck. These reports detail the errors found in the databases. System administrators should also monitor the job logs for any errors or warnings during the execution of iCheck.

How is iCheck troubleshooted?

Troubleshooting involves examining the output reports and the job logs. The reports provide detailed information about the errors found, while the job logs can indicate any issues during the execution of the iCheck job. Corrective actions depend on the specific errors reported.

What are the backup and recovery considerations for iCheck?

Backup and recovery procedures are not specific to iCheck, but rather to the IMS databases that iCheck analyzes. Standard IMS database backup and recovery procedures should be followed to ensure data integrity and availability.

Product Overview

The architecture of Eclipse iCheck is centered around its batch processing nature on the z/OS platform. The main components include the iCheck program, the JCL job, and the control cards. The iCheck program is the core executable that performs the database analysis.

The JCL (Job Control Language) defines the execution environment, including the input datasets, the program to be executed, and the output report destinations. The control cards provide the configuration parameters, specifying the IMS databases to be checked and the types of errors to be reported. These components communicate through the z/OS operating system.

The iCheck program uses IMS APIs to access and analyze the database structures. The tool reads database blocks, examines segment pointers, and validates data relationships. The primary storage mechanism is the IMS database itself.

There are no specific network requirements or ports. Security relies on z/OS security features, such as RACF, for access control. The tool is not supported; consider alternatives like BMC AMI Database Repair for IMS, which offers similar capabilities.

Frequently Asked Questions

What is Eclipse iCheck used for?

Eclipse iCheck is a tool designed to identify and report errors within IMS database blocks, segments, and pointers. It is part of the Eclipse Reorganization Utilities suite. The tool helps in maintaining data integrity by detecting inconsistencies.

What types of errors does iCheck identify?

iCheck analyzes IMS databases to identify issues such as invalid pointers, orphaned segments, and data inconsistencies. It provides reports detailing the location and nature of these errors, which aids in database maintenance and repair.

What is the main use case for Eclipse iCheck?

The primary use case is to ensure data integrity within IMS databases. By identifying and reporting errors, iCheck helps prevent data corruption and ensures the reliability of applications that rely on the IMS data.

When should iCheck be used?

iCheck is typically used as part of a broader database maintenance strategy. It can be run periodically to proactively identify and address potential issues before they impact application performance or data integrity. It is often used before or after database reorganizations.
