Existing instances are designed to be as independent as possible from the effects of subsequent installation and removal of products.
In most cases, existing instances automatically inherit or lose access to the function of the product being installed or removed. However, if certain executables or components are installed or removed, existing instances do not automatically inherit the new system configuration parameters or gain access to all the additional function. The instance must be updated.
If DB2 is updated by installing a PTF or a patch, all the existing DB2 instances should be updated using the db2iupdt command. You should also update the Administration Server using the dasiupdt command. See "Updating the Administration Server" for further information.
Running the db2iupdt command updates the specified instance by performing the following:
The db2iupdt command is available in the
||where DB2DIR||= /usr/lpp/db2_05_00||on AIX|
||= /opt/IBMdb2/V5.0||on Solaris|
Because INSTHOME is mounted, you only have to run the
db2iupdt command once to update the instance.
The syntax of the db2iupdt command is:
|Note:||FencedID may not be root or bin.|
If a server product is installed, the syntax is:
db2iupdt -u FencedID InstName
db2iupdt -u db2fenc1 db2inst1
The db2iupdt command updates the files in the INSTHOME/sqllib directory, where INSTHOME is the home directory of the instance owner.
