Full manual diffs (C50, R30, C60, L20, C40, L35, R10, R20, J10, L30, L50, P30, G10, C10) and read-only checks on the shared R1.05 test server where the permission system allowed them. Skills and summaries moved to R1.05. Issues ISS-092..129 (gaps 104-107, 114-115, 130-131 unused); ISS-074 closed (manual and software agree), ISS-091 corrected by ISS-119. version-differences: unlisted manual changes and installed-only changes. r105-verification: V5-V9 and new not-tested rows.

# Database consistency check (dsschk)
|
|
|
|
Needs CI Server running. Checking is read-only; **repair (`-r`) changes the database**:
|
|
back up first and ask the user.
|
|
|
|
## Check
|
|
|
|
```
|
|
dsschk -e -v > dsschk.out
|
|
```
|
|
|
|
- `-e` extended check: also compares the duplicated datasets on this node (e.g. item
|
|
definitions copied by ITEM and EQUIPMENT Services). This is the useful check on a
|
|
**single-node** system.
|
|
- `-v` verbose. Output lists `DSSP-I-CDS_START` / `DSSP-I-CDS_END` per dataset (228 on the
|
|
R1.03 test system, 231 on the R1.05 test server) and any problems; the same messages go to `%TLS_LOG_PATH%\umhlog.log`.
|
|
- `-d <dataset>` checks one dataset; `-n <node>` one node.
|
|
- Plain `dsschk` (no `-e`) only compares copies **between nodes**, so on a single node it
|
|
prints nothing.
|
|
|
|
Look for warnings or errors: search the output for `-W-`, `-E-` or `-F-`. None = consistent
|
|
(R1.05 test server, 2026-10-08: none).
|
|
|
|
## Repair (not yet practiced)
|
|
|
|
From IM 36K10J10 §4.1.1: run `dsschk -r` until no more inconsistencies are reported (or the
|
|
same ones repeat), then `dsschk -e`, then `dsschk -e -r` (possibly twice). Read the output
|
|
carefully; some problems need manual work.
|
|
|
|
## ISAM files (not yet practiced)
|
|
|
|
`ismchk <database file>` checks one ISAM file; `ismkfr [-c] [-r] [-s] [-d] <file>` rebuilds
|
|
key files. Both need the file name (without it: `usage: ismchk data_base_name`).
