VSAMLite is an automated VSAM solution for compressing your business-critical corporate data.
Increasing DASD I/O activity and lengthy backups can lead to poor system performance and slow online response times. Compressing your data using VSAMLite allows you to free up disk space and reduce DASD activity. This leads to improvements in overall system performance, shorter backup timescales and cost savings through reduced disk space usage. At the same time your end users benefit from faster application responses.
Real-time data compression
Data compression or decompression is performed in real time, with no changes required to applications accessing the compressed data, and with no hardware, program or JCL dependencies.
Proactive file analysis
VSAMLite eliminates the guesswork in choosing which files to compress by using its own integral compression analysis utility.
Reduced I/O activity
Fewer I/O operations are required to read the compressed data, leading to improvements in system performance and faster response times.
High compression ratios
Compression ratios of between 30 and 80 per cent are achievable, which not only reduces DASD consumption but also leads to a noticeable reduction in backup times.
System monitoring and analysis
Detailed statistics are provided to allow compression rates to be monitored, and a compression analysis utility models the effects of compression on your files.
