Description

You may want to terminate an ALTIBASE HDB session in abnormal behavior. In order to terminate the session, you have to connect to ALTIBASE HDB as SYSDBA.

1. Connecting as SYSDBA

   Code Block

   -bash-3.00$ isql -SYSDBA ----------------------------------------------------------------- Altibase Client Query utility. Release Version 5.5.1.0.4 Copyright 2000, ALTIBASE Corporation or its subsidiaries. All Rights Reserved. ----------------------------------------------------------------- Write UserID : sys Write Password : ISQL_CONNECTION = UNIX, SERVER = localhost, PORT_NO = 27562 iSQL(SYSDBA)>

2. Finding the session identifier which you want to terminate.
   Assume that there is a session connected from "192.168.1.84", and you want to terminate that session.

   Code Block
   iSQL(SYSDBA)> SELECT id, comm_name FROM v$session; ID COMM_NAME --------------------------------------------------------------------------------- 4 UNIX 5 TCP 192.168.1.84:35679 2 rows selected.

   The session identifier which you want to terminate is "5".
3. Terminating the session.
   You can use the query below to terminate the session by specifying the session identifier.

   Code Block
   lang sql
   ALTER DATABASE MYDB SESSION CLOSE [session identifier];

You can terminate the session #5 and verify that is terminated as shown below:

iSQL(SYSDBA)> alter database mydb session close 5;
Alter success.
iSQL(SYSDBA)> SELECT id, comm_name FROM v$session;
ID          COMM_NAME
---------------------------------------------------------------------------------
4           UNIX
1 row selected.

If an active transaction is running on the session, ALTIBASE HDB rollbacks the transaction before terminating the session. Therefore, sometimes, terminating a session may not work immediately.
