Dynamic Conﬁguration

Compressing the Conﬁguration Files

As your conﬁguration grows and changes, you may ﬁnd it necessary to

compress or expand your conﬁguration ﬁle. When you add items in a

ﬁle, records are added sequentially from the beginning of the ﬁle. If you

delete items from a conﬁguration ﬁle, the records are not immediately

recovered, so the middle of the ﬁle may contain unused records. These

unused records in the middle of the ﬁle are not available for reuse. By

compressing the ﬁle, you cause all data to be stored in a contiguous

block of records at the beginning of the ﬁle. This frees the unused

records to be reused.

Compress the ﬁles by accessing the Compress screen in NMMGR from

the utilities menu. To recover unused records enter 0 in the Number of

Additional Records ﬁeld and press the

[Compress File] function key. If

you enter a positive number, the number of free records will be

increased by the number entered. If you enter a negative number, the

number of free records will be decreased by the entered number. The

maximum ﬁle size limit is 65,535 records.

NOTE

If you compress the NMCONFIG.PUB.SYS ﬁle you must also compress

the NMCONFIX.PUB.SYS ﬁle. You will be allowed to compress the

NMCONFIX.PUB.SYS ﬁle, but will not be allowed to modify any records.

See the Using the Node Management Services Utilities manual for

additional information on how to compress the conﬁguration ﬁles.
