The SHARELIMIT parameter in the LSR pool definition specifies the percentage of the buffers and strings that CICS® should apply to the value that it calculates.
The method used by CICS to calculate LSR pool parameters and the use of the SHARELIMIT value is described in VSAM tuning: general objectives.
This parameter has no effect if both the BUFFERS and the STRINGS parameters are specified for the pool.
The SHARELIMIT parameter can be used in CICS systems with VSAM data sets.
See VSAM tuning: general objectives.
Because SHARELIMIT can be applied only to files that are allocated at initialization of the LSR pool (when the first file in the pool is opened), it is always wise to specify the decimal STRINGS and BUFFERS for an LSR pool.
The SHARELIMIT parameter is specified in the LSR pool definition. For more information, see the CICS Resource Definition Guide.
