dsmtop - Db2 text-based monitoring tool command
The dsmtop command is a simple text-based tool for monitoring, similar to the now deprecated db2top command. The dsmtop command can monitor Db2 Version 10.1 and above. It is intended primarily for use on Linux and AIX®, but will also run on, Windows although with some limitations.
ScopeThe dsmtop command is a lightweight, low-overhead tool that works in a text-only environment, such as a simple Unix command line. There is no web server and no need for a windowing environment. Monitoring is accomplished by using mon_get table functions.
You can use the dsmtop command to see key performance indicators in the same way that the db2top command worked. The dsmtop command provide
- See at a glance which connections are active, blocked, or idle.
- Running SQL
- See a list of recently run statements. Drill down is provided to see the full SQL text or run explain on a statement.
- Top Consumers
- Find which connections or activities are consuming the most CPU, IO or other resource.
- Time spent
- Shows a breakdown of where the monitored database is spending time.
dsmtop -d <database_name> -n <host_name> -r <port_number> -u <user_id>
dsmtop -d gsdb -n localhost -r 50000 -u kdeck
-p. However, this is not recommended as the password will then be visible to other users running similar commands. Once you are connected, you can save the credentials using the following menu choice:
File -> Write
Credentials are written to a file called
dsmtoprc which is located in
$HOME for Linux or UNIX systems, or
%UserProfile% for Windows. Further uses of the
dsmtop command will read from the dsmtoprc file to fill in
default values for database, host, port, user ID and password (encrypted).
Run dsmtop without re-authenticating
- The JDBC type 2 driver requires Db2 Server or Db2 Client products installed.
- For UNIX,
Linux or AIX
machines, you need to setup some environment variables such as
SHLIB_PATHto load the JDBC native library.
If these files are missing, refer to this page for information about how to generate them: Linux and UNIX environment variable settings
The dsmtop command will use the JDBC type 2 driver if you do not specify a
user ID or a password, either through the command line or from the dsmtoprc file.
You can also specify
-j 2 on the command line to explicitly use the type 2
The DDM parameter is not supported. Unsupported DDM parameter code point: 0x2460. ERRORCODE=-4499, SQLSTATE=58016
The most likely cause is a known problem that can happen if the JDBC type 2 native library in
your environment is newer than the db2jcc.jar file shipped with the
dsmtop command. To resolve this issue, you should replace the
db2jcc.jar from the dsmtop product with the
db2jcc.jar from the Db2 Server or Db2 Client that is
installed in the same machine. For example, if you have the Db2 product installed
/home/sqllib directory, you should replace
<your_base_path>/dsmtop/lib/db2jcc.jar with the
