Frequently Asked Questions
General
What does InfoPak do?
InfoPak compresses datasets and databases transparently. It integrates with existing applications without requiring code changes.
What data sources does InfoPak support?
InfoPak supports DB2, IMS, IDMS, CA Datacom/DB, VSAM, sequential, and PDS files.
How is InfoPak configured?
InfoPak uses a configuration file to define compression parameters and dataset selection criteria.
What kind of compression ratios can I expect?
InfoPak's compression ratios depend on the data characteristics. Higher redundancy leads to better compression.
Technical
How does InfoPak integrate with applications?
InfoPak uses a load library that is linked into the application's address space. Compression and decompression are performed inline.
How does InfoPak work internally?
InfoPak intercepts I/O requests and applies compression/decompression algorithms. This is transparent to the application.
Does InfoPak require special hardware?
InfoPak uses standard z/OS facilities for I/O operations. It does not require special hardware.
How do I specify which datasets to compress?
InfoPak's configuration file specifies which datasets are to be compressed. This file is read during initialization.
Business Value
What is the business value of InfoPak?
InfoPak reduces storage costs by compressing datasets. This can lead to significant savings, especially for large databases.
Does InfoPak improve performance?
InfoPak can improve application performance by reducing I/O operations. Compressed data requires less time to transfer.
How does InfoPak minimize disruption?
InfoPak's transparent compression minimizes disruption to existing applications. No code changes are required.
Can InfoPak extend the life of my storage?
InfoPak can extend the life of existing storage infrastructure by increasing its effective capacity.
Security
Is InfoPak secure?
InfoPak leverages existing z/OS security mechanisms. It does not introduce new vulnerabilities.
How is access to compressed data controlled?
InfoPak supports standard z/OS access control lists (ACLs). Access to compressed datasets is controlled by RACF or ACF2.
Does InfoPak encrypt data?
InfoPak does not encrypt data. It relies on compression to reduce storage space.
What kind of auditing capabilities exist?
InfoPak logs compression and decompression activity. These logs can be used for auditing and monitoring.
Operations
How is InfoPak configured and managed?
InfoPak is configured through a configuration file. This file specifies compression parameters and dataset selection criteria.
What kind of monitoring capabilities exist?
InfoPak provides logging capabilities. These logs can be used to monitor compression activity and identify potential issues.
How much maintenance does InfoPak require?
InfoPak requires minimal maintenance. The configuration file may need to be updated as datasets change.
What is the performance impact of InfoPak?
InfoPak's performance impact is generally low. Compression and decompression are optimized for z/OS.
