 +
Unpack setup file then change directory to '''server''' folder.<br>
 +
 
 +
j@linux:~/install$ cd server/

 +
First of all – we need to pass whole prerequisities requirements.
 +
 
 +
j@linux:~/install/server$ ./db2prereqcheck
 +
 
 +
Don´t be scared from many output lines (512+). This utility is generic for testing requirements from DB2 9.8 – DB2 10.5, including subversions. We´re interested in 10.5 installation process = first lines are important for us:
 +
 
 +
libstdc++.so.6 is installed in 64-bit, not installed in 32-bit. I bet this wouldn´t be a problem, anyway:
 +
 
 +
root@linux:~# apt-get install lib32stdc++6
 +
 
 +
Running again db2prereqcheck is verifying our action:
 +
 
 +
Validating „32 bit version of „libstdc++.so.6″ “ …
 +
  Found the 64 bit „/usr/lib/x86_64-linux-gnu/libstdc++.so.6“ in the following directory „/usr/lib/x86_64-linux-gnu“.
 +
  Found the 32 bit „/usr/lib32/libstdc++.so.6“ in the following directory „/usr/lib32“.
 +
  Requirement matched.
 +
 
 +
Done.
 +
 
 +
Validating „/lib/libpam.so*“ …
 +
  DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: „/lib/libpam.so*“.
 +
  WARNING : Requirement not matched.
 +
 
 +
is more tricky :-) It´s always when you are trying to do anything with 32-bit library inside 64-bit OS during installation 64-bit software 😉

Gestione delle istanze del DB

  • Elenco delle istanze
db2ilist

oppure dall'ambiente DB2 (db2cmd) 

DB2 GET INSTANCE
  • Per cambiare l'istanza corrente
SET DB2INSTANCE=<nome_istanza>
  • Configurazione della istanza corrente
DB2 GET DBM CFG
  • Elenco dei database contenuti nell'istanza corrente
DB2 LIST DB DIRECTORY
  • Creazione di una nuova istanza
DB2ICRT <nome-istanza>

dopo la creazione l'istanza va avviata tramite il comando: 

DB2START
  • Eliminazione di una istanza
DB2IDROP <nome-istanza>

Gestione dei database

  • Elenco dei database contenuti nell'istanza corrente
DB2 LIST DB DIRECTORY
  • Creazione di un nuovo database
DB2 CREATE DB <nomeDB> ON <nome_unita>

esempio: 

DB2 CREATE DB SAMPLE ON D:
  • Aggiunta di un utente
GRANT CONNECT ON DATABASE TO USER <nome-utente>
  • Revoca ad un utente dei diritti di accesso
REVOKE CONNECT ON DATABASE FROM USER <nome-utente>
  • Creazione dei bufferpool aggiuntivi
In caso di errori che richiedano bufferpool aggiuntivi per pagine di dimensioni diverse dal default (4K), eseguire i seguenti comandi:
CREATE BUFFERPOOL BUFFERPOOL_8K IMMEDIATE ALL DBPARTITIONNUMS SIZE 1000 AUTOMATIC PAGESIZE 8192;
CREATE BUFFERPOOL BUFFERPOOL_16K IMMEDIATE ALL DBPARTITIONNUMS SIZE 1000 AUTOMATIC PAGESIZE 16384;
CREATE BUFFERPOOL BUFFERPOOL_32K IMMEDIATE ALL DBPARTITIONNUMS SIZE 1000 AUTOMATIC PAGESIZE 32768;


  • Creazione di tablespace utente

Prima di procedere è necessario che i BUFFERPOOL corrispondenti siano disponibili. I comandi da eseguire sono i seguenti:

CREATE TABLESPACE USERSPACE4 PAGESIZE 32768 MANAGED BY SYSTEM USING ('<path-to-userspace>') BUFFERPOOL BUFFERPOOL_32K;


  • Creazione di tablespace di sistema
In caso di errore SQLCODE=-1585, SQLSTATE=54048, in base all'articolo della KB IBM, è necessario creare i Tablespace di sistema aggiuntivi per le dimensioni di pagina mancanti (di default viene creata solo quella da 4K). Prima di procedere è necessario che i BUFFERPOOL corrispondenti siano disponibili. I comandi da eseguire sono i seguenti:
CREATE SYSTEM TEMPORARY TABLESPACE STB_8 IN DATABASE PARTITION GROUP IBMTEMPGROUP PAGESIZE 8192 MANAGED BY AUTOMATIC STORAGE USING STOGROUP IBMSTOGROUP BUFFERPOOL BUFFERPOOL_8K
CREATE SYSTEM TEMPORARY TABLESPACE STB_16 IN DATABASE PARTITION GROUP IBMTEMPGROUP PAGESIZE 16384 MANAGED BY AUTOMATIC STORAGE USING STOGROUP IBMSTOGROUP BUFFERPOOL BUFFERPOOL_16K
