Increasing the size of the SYSLGRNX table space

The SYSLGRNX directory table space contains the relative byte address (RBA) ranges showing when data sets are open for updating.

About this task

Because more members open and close data sets in a data sharing configuration, this table space is likely to grow with the addition of each new member to the data sharing group. And if you choose to copy indexes, this table space can grow even more.

Consider increasing the frequency with which you remove rows from this table space, or increasing the size. To see the definition used for SYSLGRNX, see installation job DSNTIJIN.

Procedure

To increase the space allocation for SYSLGRNX, use access method services:

  1. Stop the table space.
  2. Rename the existing SYSLGRNX data set.
  3. Define a larger SYSLGRNX data set with the original name.
  4. Using only DSN1COPY, copy the contents of the renamed data set into the new SYSLGRNX data set.
  5. Restart the table space.
