Legacy Commands and FunctionsIf you issue $ZUTIL(100) on any other platform (UNIX or OpenVMS), you receive a error.You can also get operating system information from the $ZVERSION special variable, orthe $SYSTEM.Version class methods, as follows:WRITE $SYSTEM.Version.GetCompBuildOS()See Also• $SYSTEM special variable.• $ZVERSION special variable.• $ZUTIL(67,14)—Client Operating System legacy function$ZUTIL(113) (legacy function)Reclaims routine and directory blocks.$ZUTIL(113)$ZU(113)DescriptionThis page describes the legacy function $ZUTIL(113). It is described here for compatibilitywith legacy applications. The sole use of $ZUTIL(113) is to reclaim routine object directoryblocks when upgrading ISM database directories to Caché. It is neither needed nor supportedfor Caché version 5.0 and subsequent versions. No such block space reclamation is requiredwhen upgrading databases from an earlier version of Caché to Caché version 5.0 (or anysubsequent version).When upgrading a database from ISM to Caché, it is recommended that you upgrade in twostages: First upgrade from ISM to a pre-5.0 version of Caché, and execute $ZUTIL(113) toreclaim block space. Then upgrade from that version of Caché to Caché version 5.0 (or subsequent).$ZUTIL(113) reclaims unneeded routine object directory blocks resulting from a conversionfrom ISM to Caché. $ZUTIL(113) is not supported in Caché version 5.0 (or subsequent version).The $ZUTIL(49) function can be used to determine the current block size and maximumblock size.788 Caché ObjectScript Reference

This function supports ViewPointsystem monitoring. $ZUTIL(133) is described here for compatibility with legacy applications.$ZUTIL(133) allows you to maintain a set of metric counters for an application and supplythese counters to ViewPoint. $ZUTIL(133) consists of eight subfunctions, as follows:n= 1n= 2n= 3n= 4n= 5n= 6n= 7n= 8Create a metric counters table.Add a counter to a metric counters table.Enable (show) or disable (hide) a table. When a table is hidden its countervalues are not displayed, but counters continue to increment.Retrieve table and counter definitions. You can retrieve the total number oftables defined, retrieve the definition of a table, or retrieve the definition of acounter within a table.Increment (or decrement) the value of a counter.Set a counter to a specified value, or return the current value of a counter.Display the current values for all counters.Show metrics status, enable, or disable metrics.Caché ObjectScript Reference 789
