The body of the request contains one or more documents to be indexed. Each document is associated with an action: upload, merge, merge Or Upload, or delete.

For example, if the largest record number allowed for any record in the file is 600, but the largest record number specified for a record is 200, then RMS allocates only enough space for 200 records.

When you initially populate a file and you plan to fill the entire file through the maximum record number, you can cause RMS to use either of the following techniques to allocate space for the entire file: These techniques can optimize the throughput for the subsequent file additions, because RMS will not need to perform repeated extensions to the file as records are added.

The specific delay depends on the load on the service.

Successful indexing is indicated by the The error Message property will indicate the reason for the indexing error if possible.

For example, it signals the KEY condition when a relative record number exceeds the maximum record number specified for the file, or when the number of a record that already exists is specified in a KEYFROM option in a WRITE statement. NUMBER); /* Get new value */ GOTO GET_DATA; /* Go get other info */ END; END; . In an indexed sequential file, the file contains data records and pointers to the records.

The following sample ON-unit shows how to detect whether a record already exists in a relative file or whether a record number specified exceeds the file's maximum record number. NUMBER); /* Get new value */ GOTO GET_DATA; /* Go get other data */ END; /* Check for maximum record number exceeded */ ELSE IF ONCODE = RMS$_MRN THEN DO; PUT SKIP EDIT('Part number', PARTLIST.
