This screen provides information about AIJ journal performance. The following information is examined: o AIJ journaling status o Database configuration o Reserved journals o AIJ log server (ALS) status o Journal overwrite o Default allocation o AIJ backup server (ABS) and backup file names You can use the information in this screen to ensure that AIJ journals are on their own device. You can also examine the AIJ request block to I/O ratio, blocks per I/O ratio, and the formatting of the AIJ request block. Information in the AIJ Analysis screen is displayed only if it exceeds established threshold values or normal expectations. Note that the items identified in this screen are not necessarily indications of performance problems. The items may be an indication of a performance problem, but in most cases, further research is necessary. The AIJ Analysis screen has a configuration submenu that allows you to set thresholds for the following: o Seconds to AIJ extend/switch The default threshold is 60. You can override the default value with the RDM$BIND_STATS_AIJ_SEC_TO_EXTEND logical name. o ARBs per AIJ I/O The default threshold is 2. You can override the default value with the RDM$BIND_STATS_AIJ_ARBS_PER_IO logical name. o Blocks per AIJ I/O The default threshold is 2. You can override the default value with the RDM$BIND_STATS_AIJ_BLKS_PER_IO logical name. o Background ARB threshold The default threshold is 50. You can override the default value with the RDM$BIND_STATS_AIJ_BKGRD_ARB_RATIO logical name. o Cache overflow threshold The default threshold is 10. You can override the default value with the RDM$BIND_STATS_CACHE_OVF_RATIO logical name. o Network bandwidth threshold The default threshold is 60 seconds. You can override the default value with the RDM$BIND_STATS_AIJ_NETWORK_BPS logical name. Note that the Online Analysis facility uses the actual database parameters and attributes specified using interactive SQL. The Online Analysis facility does not use the Dashboard facility because the Database Dashboard attributes are temporary settings. Therefore, online changes made using the Dashboard facility are not reflected in the analysis output. Yet, using the Dashboard facility is the recommended method for testing potential database attribute settings. You must use interactive SQL in order to make the attribute settings persistent. Also note that the Online Analysis facility is invoked at the designated screen refresh interval. As the Online Analysis facility is fairly CPU intensive, and the analysis results seldom vary greatly over a miniscule period of time, it is recommended that the screen refresh interval be set to 3 seconds or more. The AIJ Analysis screen is not recorded in the binary output file produced using the Output qualifier. Consequently, this screen is not available when you replay a binary file using the Input qualifier.
