Variable Storage Pool

The following sysgen reports (CREPORTS) and DCMT functions can be used to monitor the use of the storage pool:

• CREPORT 25 verifies the size of the storage pool and indicates whether storage protection has been enabled for the system.
• DCMT DISPLAY ACTIVE STORAGE shows the current fragmentation of the storage pool.
• DCMT DISPLAY LTERM indicates which terminals are active and own resources.
• DCMT DISPLAY LTERM logical-terminal-id RESOURCES displays the specific resources (and the addresses of those resources) owned by the named terminal.
• DCMT DISPLAY MEMORY can be used to display an actual resource as it appears in memory.
• CREPORT 40 supplies the current parameters specified in the ADSO statement, as it this example:

REPORT NO. 40                          CA-IDMS/DC ADS REPORT

                                    LISTING OF CA-ADS PARAMETERS

                                                  OBJECT REPORT

    99                ADS        ADS2        10      USER   KEEP     OFF        40

Information from the above displays and reports can be used to calculate the number of users the system can currently support, assuming various storage pool sizes.

The CA IDMS System Generation Guide manual describes CREPORTS; the CA IDMS System Operations Guide manual details the master terminal functions available to monitor system resources.
