Configuring Packages and Their Services
Choosing Package Modules
Chapter 6300
Requires an operator and a value. Values can be string or numeric.The
legal operators are =, !=, >, <, >=, or <=, depending on the type of value.
If the type is string, then only = and != are valid. If the string contains
white space, it must be enclosed in quotes. String values are
case-sensitive.
The maximum length of the entire resource_up_value string is 1024
characters.
You can configure a total of 15 resource_up_values per package. For
example, if there is only one resource (resource_name) in the package,
then a maximum of 15 resource_up_values can be defined. If two
resource_names are defined and one of them has 10
resource_up_values, then the other resource_name can have only 5
resource_up_values.
concurrent_vgchange_operations Specifies the number of concurrent
volume group activations or deactivations allowed during package
startup or shutdown.
Legal value is any number greater than zero. The default is 1.
If a package activates a large number of volume groups, you can improve
the package’s start-up and shutdown performance by carefully tuning
this parameter.
Tune performance by increasing the number a little at a time and
monitoring the effect on performance at each step; stop increasing it, or
reset it to a lower level, as soon as performance starts to level off or
decline.
Factors you need to take into account include the number of CPUs, the
amount of available memory, the HP-UX kernel settings for nfile and
nproc, and the number and characteristics of other packages that will be
running on the node.
