Performance

Are you making the most of your investment?

We specialise in helping customers make the right decisions when it comes to looking at system and application performance on i5, iSeries and AS/400 servers. Whether your server is exhibiting general throughput degradation, or intermittent deterioration in response times, we can help you understand the root cause, and assist you in making informed and accurate decisions to overcome the problem.

LPAR capacity planning, to optimise accurate and appropriate resource assignment
Tailored “What-if” analysis, to match system throughput to your business drivers and growth plans
Application trace analysis to pinpoint design anomalies and redundant code execution

Trend analysis.

To gain a clearer picture of what lies ahead, it’s crucial to maintain an ongoing routine of performance data collection. We actively encourage customers to be in the habit of collecting performance data, and can assist you in putting an appropriate regime in place to help you stay informed:

iSeries Navigator configuration and training

Collection services setup
Management Central
Message handling and escalation automation

Performance Tools configuration and training

Data conversion from Management Collection objects (*MGTCOL)
Advisor functions
Reporting and graphing

Proactive Monitoring.

We have developed a product that provides an enhanced view onto the standard IBM Performance Tools licensed program output, giving you a more precise picture of how your system copes with changes in workloads. Our Key Performance Indicator (KPI) utilities allow you to:

Manage performance data retention and archiving
View, print and e-mail compact graphical charts of performance data over an extended period
View memory contention between private and shared pools over time
Pinpoint the relationship between key peaks and troughs in performance relative to:

Disk activity
CPU activity by job-type
Page faulting
Pool sizes
Response times
Interactive job counts
IOP saturation

Application and communications analysis.

For those more specific performance issues, we will analyse individual job trace data to build a response profile based on a fixed time-line – this allows you to see and compare the key points during an a number of test iterations where there are excessive I/O requests, looping invocations, idle-times etc.

With High Availability and becoming more widespread within the AS/400, iSeries and i5 marketplace, many customers are more concerned with managing the impact this type of product can have on the stability of their LAN and WAN infrastructure. We can assist in providing summary reports and statistics derived from Performance Data and communications traces, to help pinpoint any issues that relate directly to your iSeries communications adapters – equally we are often asked to help clarify that such issues are indeed external to and AS/400, iSeries or i5 system, to help narrow down the scope of fault identification and rectification activities within the LAN/WAN environment.
