how would I be able to calculate the Redo rate for using in the Required bandwidth Formula as seen below :
Required bandwidth Formula ((Redo rate in bytes per second / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
Example: 385 KB/sec peak rate would require an available network bandwidth of at least
((394253 / 0.7) * 8) / 1,000,000 = 4.5 Mbps.
SOURCE OF FORMULA Network Bandwidth Implications of Oracle Data Guard...I'm using Oracle 10g
I need to calculate the redo log volume generated by certain tables. If I have 100 tables in the database I need to know only 25 tables redolog vloume per day. How I can calculate this , Is the log miner useful on this issue.
View 6 Replies View RelatedBefore I begin, I want to clarify that I am newbie in the administration of data warehouse.I need to know how to calculate the sizes of the archive and redo on data warehouse DB, in order to make an initial sizing of the BD on disks level.
Is there a formula to calculate the size?
This is my sample code:
create table myReport(
report_id integer,
product_class_id integer,
place_id integer,
[code]...
would like to get the rate for my report table base. The search for the rate first will be base on product_class_id, year and place_id, second if the report row match the product_class_id and year but not place_id it should get the default rate (in my rate table the place_id is null).
Last if the report row doesn't match any key the result should be zero.This is my result query, how can I do this query?
report_id product_class_id place_id fy rate

A.2.2 Writing Backup Scripts for Disk and Tape Scenarios
As in the disk-only scenarios, the backup scripts in this section are categorized based on database workload. as stated very clearly it depends on the workload, more precisely the rate of block change. The size of the database can be found out based on formula from

so how would I know the rate of block change in order to know which script is suitable for me? I try to find out the rate of block change for the database based on change tracking file but based on

Quote:
The size of the change tracking file is proportional to the size of the database and the number of enabled threads of redo. The size is not related to the frequency of updates to the database. So how do I determine the rate of change? can the rate of block change based on size of archive logs?
I have the following information with me:

If I have a database size of 92G, based on the archive log size of about 3G per day, can I conclude that a change of 3G/92G is considered as few block change?

View 1 Replies View RelatedI look after a database that contains GIS mapping data. We do not use Oracle Spatial - it's just a plain Oracle Standard DB. It is running in Noarchivelog mode (I know - it's not a good idea, but will be sorted when our new Sun T4-1 arrives).
There are only a couple of users who actually edit data in the database, but about 100 simultaneous users who access it. In day to day use we have no performance issues. The DB has 3 50Mb redo log groups, and these switch about every hour or so during normal use.
Every few weeks we do a bulk update of our underlying map data. This involves putting about 4Gb of data into the database (which is about 15Gb in total). This takes about 5 hours and whilst I'm sure our old Sun v240 server lacking power is a substantial cause, I think the lack of redo space makes matters worse. Last time we did this, the system clocked just over 200 redo log switches in 5 hours. There were lots of "Checkpoint Incomplete" messages in the log file too.
The software we use to load the map data doesn't allow the data to be loaded with a nologging switch.
I could resize the redo logs, but if I size them for the update workload - 3x 500Mb - we'll have some days where we don't get a redo log switch at all. Is this necessarily a problem?
The alternative I'm thinking of is prior to performing this update, we add an extra redo log group with a 1Gb file, run the update, then remove the redo log group and delete the file afterwards. Is there anything wrong with this approach?
I want to calculate the running percentage. sample data is as below.
