DB2 List Databases

DB2 List Databases

Definition of DB2 List Databases

DB2 provides the different kinds of dominates to the user, roll databases is one of the words that are provided by the DB2. By using DB2 listing databases command we can list all databases from the neighbourhood server. Mostly, the database directory is used by countless parties every day. The database index collects the information for connecting to databases. Sometimes useds need to list all databases from the neighbourhood organization or remote system. At that time we applied the DB2 list databases require. When we initiate the database then all details about the database, storage device, configuration file, and counters are stored under the database directory.

Syntax 😛 TAGEND

db2 directory database directory

Explanation 😛 TAGEND

In the above syntax, we use the list database command to list all databases from the neighbourhood system.

How to schedule databases in DB2?

Now let’s see how the schedule bid works in DB2 as follows.

Basically, the inventory database dominate is used to list all content of the system database directory that we need. If we specify the road then it returns the contents of the local database index. When we need to list the content of the database at that time we need to consider some parameters as follows.

Scope

On the off probability that this command is given without the ON path boundary, the framework data set registry is returned. This data is something similar at all data set grants. On the off opportunity that the ON path boundary is indicated, the nearby data set index on that way is returned. This data isn't something very similar at all data set parts.

Authorization

We don’t require any authorization; we immediately fetch the content from the system database directory because directory busines uses locally only.

Database Alias

The database alias is used when we create a database or cataloged it. If we don’t specify the alias then the roster database command uses the database list parameter when the database was recorded.

Database name

This is used to database name when we created a database or we can say that when the database was recorded.

Local database directory

The local database index represents which is something we accumulated the database. This subject is replenished in simply if the framework database index has been checked.

Database directory

The database index specifies where the database is placed. This battlefield is crowded in only if the neighbourhood database index has been filtered.

Node name

This name is used for remote nodes. This refer compares to the value enrolled for the node name parameter when the data set and the hub were listed.

Database release level

The release level of the database manager can work on the information base.

Comment

Any remarks related to the database that was opened when it was indexed.

Directory entry type

The specified locale of the database 😛 TAGEND

A Remote entry is used to show where the database is located. An Indirect entry is used to show the database is stored on the local plan. Databases that are is available on a same node as the system database directory are believed to in an incidental nature citation the residence area( to a nearby data set registry) and are viewed as backhanded transitions. A Residence record demonstrates that the database directory is in a similar way as the neighborhood information base registry. An LDAP entry shows that the database location records are put away on an LDAP server.

All introductions of the system database directory are either remote point off or backhanded. All enters from the regional database indices are recognized in the system database set registry as aberrant sections.

Authentication

The validation means authentication character listed at the client-side.

Catalog database apportion number

Determines which centre is the catalog database partition. This is the data set parcel on which the CREATE DATABASE succession was given.

Database apportion number

Determines the amount that is demoted in db2nodes. cfg to the hub where the order was given.

Alternate server hostname

Determines the hostname or the IP address for the substitute employee to be exploited when there is correspondence disappointment on business associations with the information base. This subject is shown plainly for the system database directory.

Alternate server port number

Indicates the port multitude for the alter server to be implemented when there is correspondence disappointment on the association with the database. This subject is shown plainly for the system database directory.

Alternate server node name

On the off risk that the registry region category is LDAP, expresses the node name for the alter server to be exploited when there is correspondence disappointment on the association with the database.

Alternate server gateway node name

On the off fortune that the directory entry category is LDAP, marks the entryway hub name for the replacement door to be exploited when there is correspondence disappointment on business associations with the database.

Utilization notes

Despite the DB2 LDAP CACHE random variable setting, if utilizing the LIST DATABASE DIRECTORY or the LIST NODE DIRECTORY commands, the roll of the specific regional database provide and node introductions are spoken from the LDAP worker.

There can be a limit of eight opened database catalog examines per evaluate. To hit this restriction for a gather record that issues in excess of eight LIST DATABASE DIRECTORY commands inside a lone Db2, convert the clump certificate into a eggshell script. The "db2" prefix initiates another Db2 meeting for each order.

Sample

Now let’s envision the examples of list dominates in DB2 as follows.

list database directory

Explanation

In the above example, we use the list database command to roster out the all material from the system directory. After executions of the above command, it establishes all databases one by one that is recorded. It proves all detailed information about the database. The aspiration out we show by using the following screenshot as follows.
