o To use the RMU Monitor Start command, you must have either the OpenVMS SETPRV privilege or the OpenVMS WORLD, CMKRNL, DETACH, PSWAPM, ALTPRI, PRMMBX, SYSGBL, SYSNAM, SYSPRV, and BYPASS privileges. o If the monitor has not been started on the system previously, use the RMONSTART.COM command file (which, by default, is located in the SYS$STARTUP directory) instead of the RMU Monitor Start command. o Start the monitor from the SYSTEM account, which has the SETPRV privilege. The process starting the monitor attempts to give RDMS_MONITOR all privileges. In particular, the privileges required are ALTPRI, CMKRNL, DETACH, PSWAPM, PRMMBX, SETPRV, SYSGBL, SYSNAM, and WORLD. o The monitor process inherits some quotas, such as MAXDETACH, and the user name of the user who starts it. This can result in severe restrictions on user access. For example, if the user who starts the monitor has a MAXDETACH quota of two, then the monitor can only start two recovery processes at one time. However, the system defines most of the quotas needed by the monitor. o If the LNM$PERMANENT_MAILBOX table is not defined in the LNM$SYSTEM_TABLE logical name table, either of the following might occur: - The RMU Start Monitor command hangs - You receive the error, "monitor is not running", when you know it is. By default, the LNM$PERMANENT_MAILBOX table is defined in the LNM$SYSTEM_TABLE logical name table. However, sometimes a user or third-party application redefines the LNM$PERMANENT_MAILBOX table in another logical name table (such as the LNM$GROUP table). To recover from this situation, follow these steps: 1. Define the LNM$PERMANENT_MAILBOX table in the LNM$SYSTEM_TABLE: $ DEFINE/TABLE=LNM$PROCESS_DIRECTORY LNM$PERMANENT_MAILBOX - _$ LNM$SYSTEM 2. Start the database monitor: RMU/MONITOR START 3. Start the application Or, change the application that redefines the LNM$PERMANENT_ MAILBOX table so that LNM$PERMANENT_MAILBOX is defined as a search list that includes the LNM$SYSTEM_TABLE table, as shown in the following example: $ DEFINE/TABLE=LNM$PROCESS_DIRECTORY LNM$PERMANENT_MAILBOX - _$ LNM$GROUP, LNM$SYSTEM o Use the RMU Show System command to determine the location of the monitor log file if it is not in the default location. The monitor log file may not be in the default location if someone has issued the RMU Monitor Start command and specified a location different from the default with the Output qualifier. o The monitor process should only be started by a user whose account has adequate quotas. Ideally, the monitor process should be started from the SYSTEM account. o To view the contents of monitor log file online (even when disk-based logging is disabled because of disk space problems), use the Performance Monitor and select the Monitor Log screen from the Per-Process menu. See the Oracle Rdb7 Guide to Database Performance and Tuning or the Performance Monitor Help for information about using the Performance Monitor.
