Main Features

• Increases productivity by providing an analysis of all resources available to CICS
• Finds CICS information quickly
• Identifies CICS problems quickly and provides recommendations
• It is easy to use and can be used to train new system programmers on CICS structure
• Supports all major CICS releases
• Provides a “one button” check-up on all or selected components of CICS/TS
• Provides unsurpassed analysis and tuning recommendations for VSAM files, including:
• Files that are over allocated enabling the recapture of unused space  
• Identifies files that have an incorrect CI size that may result in poor performance or disk utilization
• Identifies files with potential key compression problems, incorrect free space usage and invalid parameters
• Identifies files assigned to Non-Shared Resources (NSR) and analyzes and recommends the BUFNI assignment to ensure better look-aside hit ratios
• Provides a series of tuning options for Local Shared Resource (LSR) files so as to achieve maximum look-aside hit rates
• Provides the actual look-aside hit rates being received by individual LSR and NSR files and not just those reported by pool buffers
• Identifies improper use of CI and CA free space
• Identifies the use of incorrect parameters such as WRITECHECK,  KEYRANGES, incorrect CA size  or LSR files with SHAREOPTIONS 4 specified
• Identifies files that have not been updated in over one month to help identify unused files that may be occupying space
• Checks the selected System Initialization Table (SIT) parameters to ensure consistency and correct specifications including:
• Reviews the storage protection parameters
• Reviews the VTAM High Performance Option (HPO),  Basic Mapping Support (BMS) and use of the Link Pack Area (LPA) and assists in recovering CPU cycles or real storage
• Reviews the timing parameters (ICV, ICVTSD and ICVR) to ensure correct specifications to reduce unnecessary CPU cycle usage
• Reviews important Language Environment (CEECOPT) parameters highlighting possible incorrect specifications that can result in wasted storage and/or CPU cycles and provides suggested values
• Provides a wealth of information including:
• Temporary Storage (TS) DFHTEMP CI Size and buffer recommendation
• Temporary Storage and Transient Data string and buffer statistics
• The aging of Temporary Storage queues and identification of TS queues that have gone unreferenced for the longest time
• Information regarding transactions defined to DB2
• Active DB2 transactions
• Thread analysis for DB2 including thread use and recommendations for thread assignments
• Operating system information such as CPU usage by TCB, paging rates, Unreferenced Interval Count (UIC)
• CPU and service units used by address spaces and summarized into different groups such as DB2, Sockets, MQ Series, CICS and operating system
• Enqueue analysis including tasks waiting for resources as well as tasks owning more than one resource
• LSR buffer reconciliation to VSAM data set CI sizes that identify buffer fragmentation or incorrect buffer definition that wastes virtual storage
• VSAM file buffer use that identifies how many LSR buffers are being used by the file out of the pool of buffers.  In addition, the contents of each allocated buffer can be viewed
• Powerful memory display that allows for searches in either EBCDIC or ASCII in either upper or mixed (upper and lower case) mode (Important for web support)
• Provides the capability to issue and view VTAM commands issued directly from CICS/TS
• C\TREK can be used to train system programmers on the CICS/TS internal structure and performance tuning
• Reviews DB2 thread assignments and provides recommendations on the current thread assignment
• Provides a real-time display of the CICS/TS statistics available by using the STAT transaction (DFH$STAT Group)
• If authorized. C\TREK allows you to:
• Purge tasks
• Purge TS and TD queues
• Open and close files
• New copy a program including a resident program
• Allows the capacity to alter CICS storage
• Purge ICE and outstanding AID requests
• Over 700 different displays available
• Over 700 different displays available
