SUPPORT / SAMPLES & SAS NOTES
Problem Note 63776: The error "Pack/Unpack buffer too small" occurs when you open a data service using the SAS® Scalable Performance Data Server driver
 |  |  |  |  |
If you define a SAS® Federation Server connection string with the SAS Scalable Performance Data Server, and the string contains a large number of schemas, the following error can occur when the data service is opened:
Pack/Unpack buffer too small.
The error does not occur when you define the data service. Investigations have shown that more than 20 schemas being defined in the connection string are likely to produce the error. The exact number of schemas that will generate the error depends on the length of the connection string.
The following syntax is an example of code that can encounter this issue:
proc fedsql
conn="driver=spds;locale='en_us';serv=port-number;
host='host-name';uid=user-id;catalog=catalog-identifier;
dbq='domain';
schema=(name=s1;dbq='domain');
schema=(name=s2;dbq='domain');
. . . more data . . .
schema=(name=s29;dbq='domain');
schema=(name=s30;dbq='domain');";
create table catalog-identifier.S30.t1 (d1 double, d2 double);
drop table catalog-identifier.S30.t1;
quit;
conn="driver=spds;locale='en_us';serv=port-number;
host='host-name';uid=user-id;catalog=catalog-identifier;
dbq='domain';
schema=(name=s1;dbq='domain');
schema=(name=s2;dbq='domain');
. . . more data . . .
schema=(name=s29;dbq='domain');
schema=(name=s30;dbq='domain');";
create table catalog-identifier.S30.t1 (d1 double, d2 double);
drop table catalog-identifier.S30.t1;
quit;
