To find space used by a database user Query to find space used by a database user. Following query can be used to know the space used by the logged in user in MBs: SELECT sum(bytes)/1024/1024 user_size FROM user_segments; Query to find the space occupied by all the users in a database. This requires access to dba_segments table: SELECT owner, sum(bytes)/1024/1024 total_size FROM dba_segments GROUP BY owner ORDER BY total_size DESC; Total space occupied by all users: SELECT sum(bytes)/1024/1024 total_size FROM dba_segments;

To find Database Size The database mainly comprises of datafiles, temp files and redo log files. The biggest portion of a database’s size comes from the datafiles. To find out how many megabytes are allocated to all datafiles: SELECT sum(bytes)/1024/1024 data_size FROM dba_data_files; To get the size of all TEMP files: SELECT nvl(sum(bytes),0)/1024/1024 temp_size FROM dba_temp_files; To get the size of the on-line redo-logs: SELECT sum(bytes)/1024/1024 redo_size FROM sys.v_$log; Finally, summing up the three above, total database size can be found: SELECT (dsize.data_size + tsize.temp_size + rsize.redo_size)/1024/1024 "total_size" FROM (SELECT sum(bytes) data_size FROM dba_data_files ) dsize, (SELECT nvl(sum(bytes),0) temp_size FROM dba_temp_files ) tsize, (SELECT sum(bytes) redo_size FROM sys.v_$log ) rsize;

To find free space in temporary tablesapce: SELECT tablespace_name,SUM(bytes_used),SUM(bytes_free) FROM V$temp_space_header GROUP BY tablespace_name;

Steps to Run Autoconfig On Database Tier (DB-Tier) 1. source the APPS environment i. go to $APPL_TOP folder where APPS is installed ii. run file . APPSORA.env or APPSSID_hostname.env iii. check if the APPS environment was sourced: echo $ORACLE_HOME 2. stop Middle(APPS) Tier: i. Go to "/admin/scripts/" folder ii. run adstpall.sh 3. source the RDBMS environment i. go to your RDBMS ORACLE_HOME $ORACLE_HOME ii. source the _.env file

iii. check that the RDBMS environment was sourced echo $ORACLE_HOME 4. run Autoconfig on DB-Tier i. go to /appsutil/scripts/ folder ii. run ADAUTOCFG.SH 5. Check the Autoconfig log file i. AutoConfig log files are stored under: Application Tier /admin//log/ Database Tier /appsutil/log// ii. if you have errors (check for ERROR or FAIL words in the log files), solve it. NOTE: it is very important to solve ALL errors from Autoconfig log files before going further inusing the other AD tools (ie: adpatch, adadmin, etc.) or executing any administrative tasks. 6. Close the current TELNET/SSH/command window and open a new one where you will source the NEW environment you need (this must be done in order not to preserve old values from the old sourced environment) 7. Please source the APPS environment i. go to $APPL_TOP folder where APPS is installed ii. run file . APPSORA.env or APPSSID_hostname.env iii. check if the APPS environment was sourced: echo $ORACLE_HOME 8. Restart the Middle (APPS) Tier i. Go to "/admin/scripts/" folder ii. run adstrtal.sh
