After the successful installation, I began to read about the information, when I was "cataloging nodes and databases (cataloging node and database)" This thing confused. The word "Catalog" has a verbal meaning compared to the SYSCAT and SYSIBM catalogues of the past. Sometimes I yell at DB2: "I don't want to catalog anything, I just want to make sure I install DB2 correct

After the connection is successful, you can use tools such as coolsql to connect to the DB2 database. Because the remote DB2 database has been catalogued locally, you can use the local database catalog name to directly access the remote database.

Use c
as the number of columns and status of each table (N = normal; C = check pending ))
# Db2 select tabname, colcount, status FROM syscat. tables order by tabname
You can also run the load query command to view the status of a single table. For example, to view the table TEST1, run the following command:
# Db2 load query table test1

solution, there is also a way to force DB2 to select segment E for proxy/local application communication so that the database shared memory is unaffected (that is, not reduced). See the explanations that follow.
If ESTORE is enabled, you also take another segment from the database shared memory. Therefore, if you enable ESTORE, you should make sure it is at least 256MB, otherwise it will n

The most important lock in Oracle is the DML (also known as data locks) Lock. From the perspective of the lock granularity (the size of the Lock Object), Oracle DML locks have two levels: Row-level locks and table-level locks.
