The command `tcbmttest‘ is a utility for facility test and performance test. This command is used in the following format. `path‘ specifies the path of a database file. `tnum‘ specifies the number of running threads. `rnum‘ specifies the number of iterations. `lmemb‘ specifies the number of members in each leaf page. `nmemb‘ specifies the number of members in each non-leaf page. `bnum‘ specifies the number of buckets. `apow‘ specifies the power of the alignment. `fpow‘ specifies the power of the free block pool.- tcbmttest write [-tl][-td|-tb|-tt|-tx][-xm num][-df num][-nl|-nb][-rnd]pathtnumrnum[lmemb[nmemb[bnum[apow[fpow]]]]]
- Store records with keys of 8 bytes. They change as `00000001′, `00000002’…
tcbmttest read [-xm num][-df num][-nl|-nb][-wb][-rnd]pathtnum
- Retrieve all records of the database above.
tcbmttest remove [-xm num][-df num][-nl|-nb][-rnd]pathtnum
- Remove all records of the database above.
tcbmttest wicked [-tl][-td|-tb|-tt|-tx][-nl|-nb][-nc]pathtnumrnum
- Perform updating operations selected at random.
tcbmttest typical [-tl][-td|-tb|-tt|-tx][-xm num][-df num][-nl|-nb][-nc][-rr num]pathtnumrnum[lmemb[nmemb[bnum[apow[fpow]]]]]
- Perform typical operations selected at random.
tcbmttest race [-tl][-td|-tb|-tt|-tx][-xm num][-df num][-nl|-nb]pathtnumrnum[lmemb[nmemb[bnum[apow[fpow]]]]]
- Perform race condition test.
