Update DB2 parameter
Ex DIAGLEVEL in DBM configuration
[tsminst1@rhlab01 ~]$ db2 get dbm cfg | grep -i diagl Diagnostic error capture level (DIAGLEVEL) = 3 [tsminst1@rhlab01 ~]$ db2 update dbm cfg using diaglevel 4 DB20000I The UPDATE DATABASE MANAGER CONFIGURATION command completed successfully. [tsminst1@rhlab01 ~]$ db2 get dbm cfg | grep -i diagl Diagnostic error capture level (DIAGLEVEL) = 4
Check the effective parameter, for the instance:
[tsminst1@rhlab01 ~]$ db2 attach to tsminst1 Instance Attachment Information Instance server = DB2/LINUXX8664 11.1.1.1 Authorization ID = TSMINST1 Local instance alias = TSMINST1 [tsminst1@rhlab01 ~]$ db2 get dbm cfg show detail Database Manager Configuration Node type = Enterprise Server Edition with local and remote clients Description Parameter Current Value Delayed Value -------------------------------------------------------------------------------------------------- Database manager configuration release level = 0x1400 ... Diagnostic error capture level (DIAGLEVEL) = 3 4
Now you can see parameter is not effective. Some parameters are dynamic, and other required a restart of the DB (db2stop / db2start).
Parameters of the instance
Some parameters can be changed.
NUMDB: 32 maximum number of database per instance FEDERATED: to be able to connect to other remote database DIAGLEVEL: default 3 can be increased to have more detail NOTIFYLEVEL: the administration notification log DIAGSIZE: if not 0, then 10% for notify and 90% for diag
Differently from Oracle, on DB2 create a user and group directly on OS level to assing specific function to a group. Ex SYSMON_GROUP is set to allow a group to do snapshots at DB2 level
SYSADM group name (SYSADM_GROUP) = TSMSRVRS SYSCTRL group name (SYSCTRL_GROUP) = SYSMAINT group name (SYSMAINT_GROUP) = SYSMON group name (SYSMON_GROUP) =
Instance parameters
DFTDBPATH: default instance path INSTANCE_MEMORY: memory for all DB on this instance (default: AUTOMATIC)
Memory usage
Memory used by instance and databases:
[tsminst1@rhlab01 ~]$ db2 get dbm cfg | grep MEM Global instance memory (% or 4KB) (INSTANCE_MEMORY) = AUTOMATIC(772705) [tsminst1@rhlab01 ~]$ db2pd -dbptnmem Database Member 0 -- Active -- Up 0 days 00:35:45 -- Date 2017-10-05-14.28.15.005832 Database Member Memory Controller Statistics Controller Automatic: Y Controller License Limit: N Controller Limit Enforced: N Memory Limit: 3090820 KB Current usage: 184512 KB HWM usage: 184512 KB Cached memory: 33024 KB Individual Memory Consumers: Name Mem Used (KB) HWM Used (KB) Cached (KB) ======================================================== DBMS-tsminst1 157568 157568 10624 FMP_RESOURCES 22528 22528 22400 PRIVATE 4416 4416 0
Memory Limit correspond to the hard limit if fixed in instance parameter INSTANCE_MEMORY (772705*4=3090820KB). If fixed, it's the memory for all DB in this instance.
Cache Memory is preallocated and not in use.
When activate a DB:
[tsminst1@rhlab01 ~]$ db2 activate db TSMDB1 DB20000I The ACTIVATE DATABASE command completed successfully. [tsminst1@rhlab01 ~]$ db2pd -dbptnmem Database Member 0 -- Active -- Up 0 days 00:49:56 -- Date 2017-10-05-14.42.26.842587 Database Member Memory Controller Statistics Controller Automatic: Y Controller License Limit: N Controller Limit Enforced: N Memory Limit: 3090820 KB Current usage: 2148672 KB HWM usage: 2148672 KB Cached memory: 346176 KB Individual Memory Consumers: Name Mem Used (KB) HWM Used (KB) Cached (KB) ======================================================== APPL-TSMDB1 160000 160000 158976 DBMS-tsminst1 157568 157568 10624 FMP_RESOURCES 22528 22528 22400 PRIVATE 14080 14080 0 DB-TSMDB1 1794496 1794496 154176
You can also set a custom value for Database memory, but then you have to manage memory allocation for maybe other DB, instances…
[tsminst1@rhlab01 ~]$ db2 get db cfg for TSMDB1 | grep MEM Self tuning memory (SELF_TUNING_MEM) = ON Size of database shared memory (4KB) (DATABASE_MEMORY) = AUTOMATIC(462168) Database memory threshold (DB_MEM_THRESH) = 100 Application Memory Size (4KB) (APPL_MEMORY) = AUTOMATIC(40000)
Some parameters on the database config can't be changed, theses are set at DB creation Ex Database code set : UTF-8
[tsminst1@rhlab01 ~]$ db2 get db cfg for TSMDB1 Database Configuration for Database TSMDB1 Database configuration release level = 0x1400 Database release level = 0x1400 Database territory = C Database code page = 819 Database code set = ISO8859-1 Database country/region code = 1
Monitoring
Monitor a database table usage per:
[tsminst1@rhlab01 ~]$ db2top -d TSMDB1
d - Database l - Sessions a - Agent t - Tablespaces b - Bufferpools T - Tables D - Dynamic SQL U - Locks m - Memory s - Statements p - Members u - Utilities A - HADR F - Federation B - Bottlenecks J - Skew monitor q - Quit
DB creation
Example DB using India, non unicode DB will consume less space than UNICODE (filed needs bigger length)
[tsminst1@rhlab01 ~]$ db2 create db testdb using codeset iso-8859-15 territory in [tsminst1@rhlab01 ~]$ db2 get db cfg for testdb Database Configuration for Database testdb Database configuration release level = 0x1400 Database release level = 0x1400 Database territory = in Database code page = 923 Database code set = ISO885915 Database country/region code = 91 ... [tsminst1@rhlab01 ~]$ db2start
DB2 using SQL queries
Ex of SQL script, export a table into a file and import then into a new DB
$ cat myscipt.sql connect to MYDB; create table mytab1(id int,name varchar(8)); insert into mytab1 values=(1,'@@'); select * from mytab1; export to mytab1_exp.ixf of ixf of select * from mytab1; connect reset; connect to testdb; create table mytab1(id int,name varchar(8)); import from mytab1_exp.ixf of ixf insert into mytab1; select * from mytab1; connect reset;
Call the script
$ db2 -tvf myscipt.sql
