Server Administration :: Estimating Size Of Database / Datafiles
Jul 3, 2010I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.
Server Administration :: Settings Infringe On Any Available Memory On System That Is Already Tight On Memory?
Jul 25, 2012I have the following setup
SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?

Server Administration :: SGA Memory Filled
Apr 14, 2012We are running oracle9i database in windows 2000 server few months before i re sized the SGA to sga_max_size =800M and pga-aggregate_target to 400M, actually we have 4gb RAM out of the we are allocated 1200Mb for SGA and PGA.
My question is if the allocated memory got filled in SGA or PGA whether the system will show any error, because when I am querying from sql> show parameter ; the sga free memory is reducing daily what will happen when it reaches its max_size.

Server Administration :: How Does SGA And PGA Split Memory When We Use MEMORY_TARGET
Mar 28, 2010I read in few blog and they are saying, oracle11g allocate 60% of the memory to SGA and 40% of the memory to PGA when we enable MEMORY_ TARGET to non-zero.Here are few blogs. URL.....It is not working on that way(60:40) on my database.
Here is my DB version.
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 Production
TNS for Linux: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production
[code]....
I am not able to find 60%:40% concept in oracle document..so all the above blogs info are wrong?
Server Administration :: Automatic Memory Management
Apr 7, 2013I have read this article:
[URL].........
And i see:
Quote:
If MEMORY_TARGET is set to non zero value:
SGA_TARGET, SGA_MAX_SIZE and PGA_AGGREGATE_TARGET are set to 0, 60% of memory mentioned in MEMORY_TARGET is allocated to SGA and rest 40% is kept for PGA.
So, I have set:
alter system set sga_target=0 scope=spfile;
alter system set pga_aggregate_target=0 scope=spfile;
alter system set sga_max_size=0 scope=spfile;
alter system set memory_max_target=512M scope=spfile;
alter system set memory_target=300M scope=spfile;
, and then bounced the instance.
After startup, I see:
SQL> startup
ORACLE instance started.
Total System Global Area 272027648 bytes
Fixed Size 1384012 bytes
Variable Size 100663732 bytes
Database Buffers 163577856 bytes
Redo Buffers 6402048 bytes
Database mounted.
Database opened.
SQL>
But Total System Global Area should't be in that case 60% of memory mentioned in MEMORY_TARGET? Memory mentioned in MEMORY_TARGET was 300M, and 60% of 300M is 180M, which is not 272027648 bytes.
I just want to use automatic memory management, so I've set the other parameters above to 0. My instance is on my local machine, so just for my own personal use.

Server Administration :: Unable To Use More Than 2GB Memory For Oracle In Windows 2003
Jun 17, 2011I have a 11g database installed on a windows 2003 server. When I created the database I could not assign more than 2GB for SGA_TARGET where as I have 16GB of RAM available on the server. I created the database with SGA_TARGET as 1.5 GB and Memory_TARGET as 2GB. I could create the database successfully. Later when I again tried to increase SGA_TARGET to 6GB and MEMORY_TARGET to 8GB, I could not start the database. I got below error;

Server Administration :: Unable To Allocate 4120 Bytes Of Shared Memory
Jan 1, 2013I have a package when it runs, it terminates with "unable to allocate 4120 bytes of shared memory"error at a particular INSERT statement. So everytime we had this error, we had to flush the shared pool area, after which it would run without issues(for 3-4 weeks).
It had a dynamic subpartition clause framed, which made it to repharse the query every time.So to reduce this, we removed the subpartition clause(made it to static query), which did benefit of not getting shared pool error.
I would like to find the current shared pool memory usage of my program.Is there a way I could find the live consumption of shared pool area of my program(pkg).

Get Percentage Calculations?
Jan 21, 2012I am fairly new to Oracle SQL developer and I am having an issue that may very simple but I just cannot work it out logically for some reason.I am trying to calculate the percentage of sales each employee has made form the total of trades. I have been trying to use the COUNT function but it obviously splits the counts for each employee. I then tried a inline view but couldn't get it to work and also a sub-query and had an issue with "not a single group function" and then "not a GROUP BY expression".
how I can do this? I will also need to add the syntax to another inline view

SQL & PL/SQL :: How To Calculate Running Percentage
Mar 13, 2013I want to calculate the running percentage. sample data is as below.
CREATE TABLE prod
(
code VARCHAR2(8),
name VARCHAR2(30),
stdate DATE,
itons NUMBER(7,3),
rtons NUMBER(7,3)
[code]....
Required Output is
CODE NAME STDATE ITONS RTONS %age
-------- ------------------------------ --------- ---------- ---------- -------
0-01-001 SEEDS 17-JUL-12 193.155 0
1-01-001 OIL 17-JUL-12 0 81.906 42.404

2-01-001 WASTE 17-JUL-12 0 5.703 2.953
[code]....
Percentage will be calculated as rtons of code not having first digit 0 devided by itons having having code 0 result multiply 100 for the same date code wise e.g. For dated 17-jul-13 meal percentage will be calculated as round((104.304/193.155)*100,3)=54.000

PL/SQL :: Count To Find Percentage
Sep 26, 2012I want to find the Pass rate for each term by adding up the grades.
PASS = HD/D/PASS FAIL = FAIL and Z means no mark has been recieved yet so i do not want to include it in the calculation.
CREATE TABLE DAN_GR
(ID VARCHAR2(8),
TERM VARCHAR2(8),
GRADE VARCHAR2(8),
SUBJECT VARCHAR2 (8),
STAT VARCHAR2 (8))
[Code]....
So term 1201 has 1 Pass 1 Fail and a Z (which is not counted) so pass rate is 50%
term 1202 has has 1 Pass only so the pass rate is 100%
term 1203 has 1 Fail so pass rate is 0%
term 1204 has 1 Pass and 2 Fails and i dont count the 3rd fail because the stat is 'APSENT' i only want to count the once where stat is 'PRESENT'
WANT:
COUNT TERM PASS RATE

1 1202 100%
1 1203 0%
3 1204 33%
