Other commercial-grade operating systems such as Chrome OS also use A/B updates successfully.A successful slot should be able to boot, run, and update itself.A bootable slot that was not marked as successful (after several attempts were made to boot from it) should be marked as unbootable by the bootloader, including changing the active slot to another bootable slot (normally to the slot running immediately before the attempt to boot into the new, active one).An example of a report generated by the script follows the script.tab_COLUMN table_name FORMAT a15 HEADING ' Table' COLUMN partition_name FORMAT a15 HEADING ' Partition' COLUMN tablespace_name FORMAT a15 HEADING ' Tablespace' COLUMN initial_extent FORMAT 9,999 HEADING ' Initial|Extent (K)' COLUMN next_extent FORMAT 9,999 HEADING ' Next|Extent (K)' COLUMN pct_increase FORMAT 999 HEADING ' PCT|Increase' SET LINES 130ttitle ' Table Sub-Partition Files For &owner1' BREAK ON table_owner ON table_name ON partition_name SPOOL tab_SELECTtable_owner, table_name, partition_name,sub-partition_name, tablespace_name, logging,initial_extent/1024 initial_extent,next_extent/1024 next_extent, pct_increase FROM sys.dba_tab_sub-partitions ORDER BY table_owner,table_name,partition_name/ SPOOL OFFInitial Next PCTTable Partition SUB-PARTITION Tablespace LOG Extent (K) Extent (K) Increase _NAME--------------- ---------- ----------- ---------- --- ------ --- ------ ---TEST5 Q1_1997 SYS_SUBP1 DATA_TBS1 YES 40 40 0 SYS_SUBP2 DATA_TBS2 YES 40 40 0SYS_SUBP4 DATA_TBS4 YES 40 40 0SYS_SUBP3 DATA_TBS3 YES 40 40 0 WEEK1 DATA_TBS1 YES 40 40 0 Q1_1998 SYS_SUBP17 DATA_TBS1 YES 40 40 0SYS_SUBP18 DATA_TBS2 YES 40 40 0 SYS_SUBP19 DATA_TBS3 YES 40 40 0SYS_SUBP20 DATA_TBS4 YES 40 40 0Q2_1997 SYS_SUBP5 DATA_TBS1 YES 40 40 0 SYS_SUBP8 DATA_TBS4 YES 40 40 0SYS_SUBP7 DATA_TBS3 YES 40 40 0SYS_SUBP6 DATA_TBS2 YES 40 40 0 Q3_1997_S2 DATA_TBS2 YES 40 40 0 Q4_1997 SYS_SUBP9 Q4_TBS1 YES 40 40 0SYS_SUBP10 Q4_TBS2 YES 40 40 0 SYS_SUBP11 Q4_TBS3 YES 40 40 0 SYS_SUBP12 Q4_TBS4 YES 40 40 0SYS_SUBP13 Q4_TBS5 YES 40 40 0 SYS_SUBP14 Q4_TBS6 YES 40 40 0SYS_SUBP15 Q4_TBS7 YES 40 40 0 SYS_SUBP16 Q4_TBS8 YES 40 40 0 Monitoring Sub-partition Statistics Statistics are gathered at the sub-partition level, just as for tables and partitions.
