'e:\oradata\users01.dbf' in above query
CHECK7: Do monitor size of temp, undo
and users tablespace while patch executions
running on. If require increase or resize
tablespace size to avoid space errors.
Procedure: Query to find free and used space in
tablespace in SQL * plus using mentioned
procedure above.
Based on DUMP file size and for patch
operations
PATH: Please mention the path to place a file i.e
'/home/oracle/app/product/oradata/users01.dbf'
in above query
Add datafiles in USERS tablespace, Increase
UNDO Tablespace, TEMP tablespace
Follow above procedure to add space in
appropriate tablespace
if dump size is 100GB then create 5 datafiles
with minimum of 2G each datafile will grow
upto 32GB with unlimited option which is
enough to complete the process
Note: ORACLE XE user data limited 4GB you can't extend space like you do in orcl database. 1
datafile with size of 4GB is suggested in ORACLE XE
Knowledge:
1. Use tablespace other than system and sysaux tablespace to store users data. Verify the
default tablespace & temp tablespace using below query
select property_name,property_value from database_properties where property_name
like '%TABLESPACE';
2. Place user datafiles in seperate hardisk or partiation.
3. Use recommanded parameters settings and on load basis reset or increase value of
parameters
4. Large DML (insert,update and delete) operations require more UNDO tablespace. Increase
the size of UNDO tablespace to avoid space errors.
5. Sorting (group by, order by, having) operations require more Temp tablespace. Increase the
size of TEMP tablespace to avoid space errors.
6. As per dump file size add require datafiles to USERS tablespace. Each datafile can have
max value of 32768 MB (32GB) to avoid space errors. Before add datafiles in USERS
tablespace do check available disk space in the appropriate directory.
Example: if dump file size is 140GB add 5 datafiles in USERS tablespace and each datafile
value 32768
7. At lease have 3 members and 2 group totally 6 redo log files for better log switch operations
and make sure each 500MB
8. Verify with alert log and trace file for error cause and do report immediately to fix issue.
