Buffer Cache Size

High CPU_COUNT and increased granule size can cause ORA-0431 error.

------CPU_COUNT specifies the number of CPUs available to Oracle. On single-CPU computers, the value of CPU_COUNT is 1.

Memory sizing depends on CPU_COUNT (No of processor groups).

Please use below formulas to calculate min buffer cache size

--Minimum Buffer Cache Size

10g : max(CPU_COUNT) * max(Granule size)

11g : max(4MB * CPU_COUNT)

Please note that If SGA_MAX_SIZE < 1GB then use Granule size = 4mb, SGA_MAX_SIZE > 1G then use Granule size = 8MB.

-- _PARALLEL_MIN_MESSAGE_POOL Size

If PARALLEL_AUTOMATIC_TUNING =TRUE then large pool is used for this area otherwise shared pool is used.

CPU_COUNT*PARALLEL_MAX_SERVERS*1.5*(OS msg bufferr size) OR CPU_COUNT*5*1.5*(OS message size)

-- Add extra 2MB per CPU_COUNT for shared pool.

Here is the example:-

Sun Solaris server has threaded CPUs. 2 physical CPUs has 8 cores, and each core has 8 threads, then Oracle evaluates CPU_COUNT = 2*8*8=128.

When SGA_MAX_SIZE=900MB,

Minimum Buffer Cache = CPU_COUNT *Granule size = 128*4M = 512MB

Shared Pool can use 338MB

When SGA_MAX_SIZE=1200MB,

Minimum Buffer Cache = CPU_COUNT *Granule size = 128*8M = 1024MB

Shared Pool can use 176 MB, so ORA-4031 occurs despite larger SGA_MAX_SIZE.

You need to manually tune CPU_COUNT parameter to resolve this error.

ORA-02049: timeout: distributed transaction waiting for lock

ORA-02049: timeout: distributed transaction waiting for lock

simoutaneously transactions

Make sure that there were no any activities on the remote database

1) select * from v$parameter where upper(name)='DISTRIBUTED_LOCK_TIMEOUT'; ----60 to 300sec

alter system set distributed_lock_timeout=300 scope=spfile;

shut immediate

startup

2) The connection remains open until you end your local session or until the number of database links for your session exceeds the value of the initialization parameter OPEN_LINKS. If you want to reduce the network overhead associated with keeping the link open, then use this clause to close the link explicitly if you do not plan to use it again in your session.

3) increase SHARED_POOL_SIZE

or free space

Memory management SGA PGA

RAM=16 GB
WINDOW PROCESS=16*20%=3.2 GB

ORACLE SERVICES=12 GB

PGA_AGGREGATE_TARGET==(RAM*80%)*50% FOR DSS
PGA_AGGREGATE_TARGET==(RAM*80%)*20% FOR OLTP


SGA_TARGET + PGA_AGGREGATE_TARGET determine how much memory oracle is going to use.

SGA_MAX_SIZE is only upper limit. Not how much oracle is going to allocate.


PGA_AGGREGATE_TARGET is not being allocated at the startup it is allocated on as needed basis, so when some server process need memory from pga_aggregate _target area this memory is being allocated by setting 1GB to PGA_AGGREGATE_TARGET you set max size for this region, so even if some process will need memory but you have already reached 1GB Oracle will not allocate more.

SGA Tuning

There are two parameters
SGA_TARGET: RAM SPACE IS ASSIGNED TO ORACLE SERVICES, CAN SEE ON TASK MANAGER PROCESS

This parameter is new with Oracle 10g. It specifies the total amaount of SGA memory available to an instance. Setting this parameter makes Oracle distribute the available memory among various components - such as shared pool (for SQL and PL/SQL), Java pool, large_pool and buffer cache - as required.

sga_target cannot be higher than sga_max_size.


If sga_max_size is less than the sum of db_cache_size + log_buffer + shared_pool_size + large_pool_size at initialization time, then the value of sga_max_size is ignored.



SGA_MAX_SIZE

This parameter sets the hard limit up to which sga_target can dynamically adjust sizes. Usually, sga_max_size and sga_target will be the same value, but there may be times when you want to have the capability to adjust for peak loads. By setting this parameter higher than sga_target, you allow dynamic adjustment of the sga_target parameter.

SGA Sizing on a dedicated server
OS Reserved RAM – This is RAM required to run the OS kernel and system functions, 20% of total RAM for MS-Windows, and 10% of total RAM for UNIX/Linux

Oracle Database Connections RAM – Each Oracle connection requires OS RAM regions for sorting and hash joins. (This does not apply when using the Oracle multi-threaded server or pga_aggregate_target .) The maximum amount of RAM required for a session is as follows:

2 MB RAM session overhead + sort_area_size + hash_area_size

Oracle SGA Sizing for RAM – This is determined by the Oracle parameter settings. The total is easily found by either the show sga command or the value of the sga_max_size parameter.


Eg. RAM=16 GB

for windows processes = 16*20%=3.5 GB reserved for windows

2MB + 64 KB + 128 KB

Oracle error 14402 : ORA-14402: updating partition KEY COLUMN would cause a partition CHANGE

The above error was caused because when you updated the record, it now belongs to a different partition but since row movement between partitions is not enabled on the table, you got that error.

It's easy to solve this problem. Just enable row movement on the table by executing the following command. You need to be logged in as the owner schema of that table or have enough privileges to do so.

ALTER TABLE enable row movement;
