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 RESOURCES indicates which terminals are active and own resources.
• DCMT DISPLAY LTERM lterm-id-a RESOURCES displays the specific resources (and the addresses of those resources) owned by the named terminal.
• DCMT DISPLAY MEMORY hex-address-a displays an actual resource as it appears in memory.
• CREPORT 40 supplies the current parameters specified in the ADSO statement.

The CA IDMS Reports Guide manual describes CREPORTS; the CA IDMS System Tasks and Operator Commands Guide details the master terminal functions available to monitor system resources.

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.
