This caused every DB2 datasource sync to fail with "catalog name can not be null", leaving status=INACTIVE and blocking all schema / table / view / column metadata reads (batch-3 cases 2.1-2.4 plus batch-4+ DB2 cases). Fix (selected option A of A/B/C tradeoff, see fix-001.md): - generateJdbcUrl: when catalogName is blank, fall back to defaultSchema (DB2 catalog = database, defaultSchema carries the DB name end-to-end from DMS-EE → odc-service → plugin) - when the resolved catalog equals defaultSchema, omit the redundant ":currentSchema=" segment (DB2 driver defaults to user.toUpperCase(), which is exactly what ConnectionConfig.getDefaultSchema returns for DB2 per B-20) - improve the fail-fast error message to mention both catalogName and defaultSchema so future regressions surface the actual missing piece - Db2ConnectionExtensionTest: add 4 regression cases (null fallback / empty fallback / catalog==schema case-insensitive / explicit catalog+distinct schema) and split the existing blank-catalog throws case into NPE-for-null and IAE-for-empty to keep Validate.notEmpty semantics explicit Test: cd server/plugins/connect-plugin-db2 && mvn test → 18 PASS / 0 FAIL.

With both fields blank the plugin-layer fallback has nothing to fall back to and we get the original "catalog name can not be null" again. Fix: - ConnectionService.adaptDb2DatabaseToCatalog(): runs in both create() and update() right after environmentAdapter / connectionSSLAdaptor and BEFORE the isDefaultSchemaRequired branch. For DB2 only, if catalogName is blank and a raw defaultSchema was provided by the caller, copy that raw value into catalogName. Explicitly never overwrites an explicit catalogName. - ConnectionService.clearDb2DefaultSchemaOnEntity(): after modelToEntity() the ConnectionConfig.getDefaultSchema() DB2 fallback would have synthesised user.toUpperCase() into the entity; that's fine for JDBC URL build but would persist a misleading value in the t_connection.default_schema column. Wipe it on the entity right before saveAndFlush so persistence stays honest (raw null) while runtime resolution keeps using getDefaultSchema(). - ConnectionConfig.getRawDefaultSchema(): @JsonIgnore helper that returns the persisted field as-is, bypassing the dialect-specific resolution in getDefaultSchema(). Required by adaptDb2DatabaseToCatalog so we can tell "the user provided no schema" from "fallback synthesised user.toUpperCase()". Together with the plugin-layer fallback this delivers the compat-RISK-7 decision B (compatibility shim): DMS-EE buildDatasourceBaseInfo contract stays unchanged, the DB2 catalog/database name flows defaultSchema → catalogName → JDBC URL transparently, and explicit catalogName overrides keep working.

ODC core consumes the return value via VersionUtils.compareVersions which calls Integer.parseInt on every dot-separated segment, so passing the raw "SQL110580" raises NumberFormatException and propagates HTTP 400 out of POST /api/v2/datasource/databases/{id}/sessions (createSessionByDatabase). With session creation broken, the entire DB2 workbench downstream stack (resource-tree table/view/index/constraint sub-nodes, SQL Console execution, "数据研发" submenu, batch-3 cases 2.2 / 2.3 / 2.4 / 3.x / 4.x / 5.x and 6.x) is blocked. This change keeps the fix inside the DB2 plugin (no impact to other dialects) and normalizes whatever the driver returns into a dotted decimal that VersionUtils can parse: 1. Already-dotted decimals pass through unchanged. 2. Free-form text containing a dotted decimal (e.g. the "DB2 v11.5.9.0" returned by SYSIBMADM.ENV_INST_INFO.SERVICE_LEVEL) gets the dotted run extracted. 3. IBM internal codes "SQL" + 6/7/8 digits get positionally decoded into V.R.M.F (e.g. SQL110580 → 11.5.8.0). 4. Anything unrecognized falls back to the sentinel "0.0.0" so the caller still gets a parseable string and a WARN is logged. Mock-only unit tests pin the bug A repro ("SQL110580" → "11.5.8.0"), exercise the map of formats the IBM driver is observed to emit, and defensively round-trip every output through VersionUtils.compareVersions to prove no input can re-introduce a throw.

The original implementation in Db2SchemaAccessor.showDatabases filtered SYSCAT.SCHEMATA by DEFINER NOT IN(...), but on DB2 11.5 several system schemas (NULLID, SQLJ, SYSTOOLS) are created by the instance owner (e.g. db2inst1) and therefore have DEFINER = db2inst1, not SYSIBM. The DEFINER predicate let those rows slip into the user schema list — see the JDBC truth table in docs/test/screenshots/case-2-1-round2-schema-definer.txt and the batch-3 round-2 failure analysis in docs/test/case-2-1.md. The fix switches the filter dimension to SCHEMANAME, which is what the design intended, and adds SQLJ to the blacklist (DB2 JDBC stored procedures schema, meaningless to end users; previously slipped through the DEFINER filter too). A new mock-only test (showDatabases_sqlFiltersBySchemaNameWithFullBlacklist) captures the SQL string with ArgumentCaptor and pins both shape ("SCHEMANAME NOT IN", not "DEFINER NOT IN") and the full 12-entry blacklist so a future refactor can't silently regress to the original DEFINER-based filtering.

Any one of those methods on the aggregator path (`OBMySQLTableExtension.getDetail`) is enough to crash the whole tab. Two-tier implementation, both in the same commit because they sit on one class and share helper state (the 12-entry SYSTEM_SCHEMA_BLACKLIST constant introduced for the view list is also reused by the schema list): A. View surface (case 2.4 — DB2INST1 → "视图" subnode + SQL autocomplete) - listAllUserViews(viewNameLike): SELECT VIEWSCHEMA, VIEWNAME FROM SYSCAT.VIEWS WHERE VIEWSCHEMA NOT IN (<12-entry blacklist>) - listAllSystemViews(viewNameLike): inverse (VIEWSCHEMA IN (...)) - listAllViews(): union of user + system - listViews(schema): per-schema variant for tree expansion - showSystemViews(schema): per-schema list for autocomplete - getView(schema, name): null (controller maps to 404, not 500) B. Table-detail aggregator surface (case 2.3 — TEST_ORDERS detail page) - getDatabase(schema): minimal POJO so OBMySQLTableExtension.getDetail can proceed (DB2 ≈ Oracle/PG where schema is the user-facing DB id) - listDatabases(): full DBDatabase list (was missing wrapper) - listTableColumns(schema, List): batch variant — loops the per-table SYSCAT.COLUMNS query (the existing per-table variant already worked); avoids throwing on every detail-page render - listTableConstraints(schema, table): SYSCAT.TABCONST with P/U/F/K -> DBConstraintType mapping (PRIMARY_KEY/UNIQUE_KEY/FOREIGN_KEY/ CHECK/UNKNOWN) - listTableIndexes(schema, table): SYSCAT.INDEXES with UNIQUERULE P/U -> unique=true, D -> unique=false - switchDatabase / syncExternalTableFiles: void / false (no-op because DB2 schema is fixed at JDBC connect time) C. Safe-degradation surface (remaining unsupported methods) Every other previously-throwing method now returns empty List/Map / null / false. Out-of-scope for this release (design.md §6 explicitly covers only schema/table/view/column/index/constraint): - PL objects: listFunctions/Procedures/Packages/PackageBodies/ Triggers/Types, listSequences/Synonyms — empty list - MView: listMViews / listAllMViewsLike / refreshMVData / listMView{Constraints,RefreshRecords,Indexes} / getMView — empty/null/false - Variables / charset / collation — empty list (DB2 surfaces via SYSPROC.* but ODC variables page not wired here) - Basic{Table,View,ExternalTable,MView,ColumnsInfo}Columns batch + per-table — empty (autocomplete optimization; falls back to heavier per-table listTableColumns path) - Schema-wide batch: listTable{Indexes,Constraints,Options, Partitions} / listTableRangePartitionInfo / listSubpartitions / listPartitionTables — empty - getTableDDL: empty string (db2look / DB2LK_GENERATE_DDL out of scope; ".contains(...)" safe on "") - getTableOptions / getPartition / getTableColumnGroups / single- object getX (View/Function/Procedure/Package/Trigger/Type/Sequence/ Synonym) — null (controller maps null -> 404, not 500) - listUsers — empty (no DB2 user picker in this release) - getTables(schema, list) — empty Map (DB2 plugin's Db2TableExtension orchestrates columns+indexes+constraints individually; this batch path is not used) D. Tests (Db2SchemaAccessorTest, +5 new mock-only cases on top of the 8 baseline from fix-G): - listViews_returnsViewIdentities (view path) - listAllUserViews_filtersSystemSchemasAndSupportsLikePredicate (view + blacklist single-source-of-truth) - listAllSystemViews_inverseOfUserViews (regression guard against accidentally swapping VIEWSCHEMA NOT IN <-> IN) - listTableColumnsBatch_loopsPerTableAndKeysByName - listTableColumnsBatch_emptyInputReturnsEmptyMap (with explicit List cast to disambiguate from String overload) - listTableIndexes_uniqueRuleMapping (P/D mapping) - listTableConstraints_typeMapping (P/U/F constraint type mapping) - getDatabase_returnsMinimalIdEqualsName (aggregator path prerequisite) - unsupportedPlaceholders_degradeToEmptyInsteadOfThrowing (regression guard for the 18 spot-checked methods that were previously throwing — pins them to empty / false / null) 13 / 13 PASS; baseline already-known SqlServerTriggerTemplateTest.setTableName compile failure is pre-existing and unrelated (see expertise_docs/episodic/odc_baseline_test_failures_2026-05-19.md). E. Compatibility - No new RISK in docs/spec/compat_risks.md: the DBSchemaAccessor contract was already published; bug D is "plugin never honored the contract". Non-DB2 plugins untouched. - vendor / go.mod / pnpm-lock not touched. - No new startup hook / no AutoMigrate / no schema migration.

The fix-H accessor commit (b9a03fcfe) implemented the column / constraint / index / DDL accessor methods but the table-detail aggregator path still crashed because `Db2TableExtension extends OBMySQLTableExtension` and inherits two OB-MySQL-specific code paths: 1. `getStatsAccessor()` → `DBAccessorUtil#getStatsAccessor` (OB-MySQL plugin's util) → `getDbVersion()` → `new OBMySQLInformationExtension() .getDBVersion(connection)` → `OBUtils.getObVersion(connection)` which runs `show variables like 'version_comment'`. DB2 jcc treats this as a non-query (DB2 has no `SHOW VARIABLES` syntax) and throws `ERRORCODE=-4476 (executeQuery used for update)` — the whole table-detail page returns 500. 2. `getDetail()` builds an `OBMySQLGetDBTableByParser(ddl)` over the string returned by `schemaAccessor.getTableDDL()`. For DB2 the accessor returns "" by design (db2look / DB2LK_GENERATE_DDL are out-of-scope per design.md §6), and the MySQL DDL parser would also be invoked on a non-MySQL grammar. The inherited body also calls `schemaAccessor.listTableColumnGroups()` which doesn't apply to DB2. Fix: override both methods in `Db2TableExtension`: - `getStatsAccessor(connection)` returns a fresh `Db2StatsAccessor` bound to the live JdbcOperations. `Db2StatsAccessor` (added in feat-839 commit d36349cd5, `libs/db-browser/.../stats/db2/`) doesn't need a version probe — it queries SYSCAT.TABLES `CARD` / `NPAGES` directly, so `OBUtils.getObVersion` is bypassed entirely. - `getDetail(connection, schema, table)` re-assembles the `DBTable` payload from four DB2-native accessor calls (columns / constraints / indexes / DDL / options) plus `getDb2TableStats(...)` (defensive wrapper around `Db2StatsAccessor.getTableStats`). Partition is set to null (DB2 partitioned tables are out of scope) and listTableColumnGroups is skipped (DB2 has no OB-style column groups). This is the same data shape OB-MySQL produces, just sourced via SYSCAT instead of the MySQL DDL parser. - `syncExternalTableFiles()` no longer throws — DB2 has no external tables in this release, so returning false matches the accessor contract that fix-H established in commit b9a03fcfe. Self-test (fix agent): - bug D-1 (case 2.4): listAllUserViews via `/odc_query/api/v2/connect/sessions//metadata/identities?type= VIEW¤tOrganizationId=1` returns HTTP 200 with 2 user views (DB2INST1.TEST_VIEW_001, DB2INST1.V_TEST_ORDERS_SUMMARY) — was 500 before fix-H accessor commit; PASS. - bug D-2 (case 2.3): getTable for TEST_ORDERS via `/odc_query/api/v2/connect/sessions//databases/DB2INST1/tables/ VEVTVF9PUkRFUlM%3D?currentOrganizationId=1` — verified after this commit + restart.

The pf4j manifest (META-INF/extensions.idx, auto-generated from @Extension) was therefore missing the ViewExtensionPoint binding for DB2, and the front-end resource tree silently omitted the "视图" category node under each DB2 schema (case 2.4 view-list regression). Changes: * server/plugins/schema-plugin-db2/Db2ViewExtension — extends OBMySQLViewExtension and overrides three protected hooks: - getSchemaAccessor → DBAccessorUtil.getSchemaAccessor (routes to Db2SchemaAccessor) - getOperator → Db2ObjectOperator (DB2 double-quoted identifiers, not MySQL backticks) - getTemplate → OB-MySQL view template factory (DBViewTemplateFactory.buildForDB2() throws UnsupportedOperationException; the OB-MySQL template emits a generic "select * from ..." scaffold that's DB2-compatible for the wizard skeleton) * libs/db-browser Db2SchemaAccessor.listViews — switch the SQL from "SELECT VIEWSCHEMA, TABNAME FROM SYSCAT.VIEWS" to "SELECT VIEWSCHEMA, VIEWNAME FROM SYSCAT.VIEWS". SYSCAT.VIEWS does not surface a TABNAME column (that's on SYSCAT.TABLES); the inherited skeleton produced SQLCODE=-206 (SQLERRMC=TABNAME) as soon as fix-I wired the v1 controller in. * server/odc-migrate ... R_2_0_0__initialize_version_diff_config.sql — append a support_view='true' row for DB2 so VersionDiffConfigService#getSupportFeatures includes view in the front-end supports[] array; without it, even with the ViewExtensionPoint registered, the resource tree still hides "视图". * Db2ViewExtensionTest — 9 mock-only unit tests pin the list/listSystemViews/ getDetail delegation, the drop operator routing, and the @Extension annotation + OBMySQLViewExtension inheritance contract. * Db2SchemaAccessorTest.listViews_returnsViewIdentities — pin VIEWNAME (not TABNAME) in the executed SQL via ArgumentCaptor.

The HTTP request 400-ed and the UI data tab spinner never resolved, blocking case 3.1 (table data pagination + type echo) and case 3.2 (CLOB/BLOB cell view). Changes: * ConnectConsoleService.queryTableOrViewData L175 — append an isDb2 branch that selects OracleSqlBuilder (not MySQLSqlBuilder). Both DB2 and Oracle quote identifiers with ANSI double quotes; the MySQL builder emits backticks which DB2 jcc rejects with SQLCODE=-104 SQLSTATE=42601. * ConnectConsoleService.queryTableOrViewData L208 — append an isDb2 branch on the row-limit clause. DB2 uses ANSI "FETCH FIRST n ROWS ONLY", not MySQL-style "LIMIT n". Although DB2 11.x has a sql_compat MYSQL mode that accepts LIMIT, the default DB2 grammar (which our test instance runs) rejects it; FETCH FIRST is portable across DB2 versions and matches our 11.5 test bed. * DataConverters.java — peer of the same dialect grep: TableDataService's data- edit path (case 4.x) routes DB2 through MySQLDMLBuilder.toSQLString, which delegates to DataConvertUtil → DataConverters. DataConverters threw "Illegal DialectType DB2" for any dialect other than Oracle/MySQL/Doris/TiDB, which would 500 the row-edit save flow once case 4.x runs. Reuse initForMysqlMode for DB2 — per design.md §2.5, DB2 and MySQL agree on basic string/numeric literal grammar for the editor MVP. Verified by global grep of dialectType.is{Mysql,Oracle,Dm,Doris,Tidb,SqlServer} across odc-service; remaining hits are single-point checks where DB2 safely falls into the else branch (e.g. OdcStatementCallBack only enables Oracle- specific dbms_output cleanup, ConnectionSessionFactory only routes Oracle schemaName logic). Other dialect-routing if/else chains already had DB2 branches added in earlier feat-839 commits (DruidDataSourceFactory L135, TableDataService L101, ConnectionTesting L166).

After fix-I unblocked the queryTableOrViewData HTTP path (400 -> 200), this jcc error became the next bug along the recursive chain: queryData now returns 200 + status=FAILED + rows=[], the data tab spinner never resolves and the user sees no rows for any DB2 table that has a LOB column. Root cause: GeneralLobMapper.mapCell always calls CellData#getBinaryStream even when the column is a character LOB. For OB / MySQL / Oracle this happens to work because their drivers happily expose the BLOB-style stream for CLOBs; DB2 jcc is strict and reports the type error. Fix (odc-core layer, not plugin-specific): * GeneralLobMapper now classifies columns by typeName. CLOB / NCLOB / DBCLOB go through Clob#length() (jcc-safe); other LOB types continue to use Blob#length() when available and fall back to InputStream#available() so existing OB / MySQL behaviour is preserved. * GeneralLobMapper now recognises DBCLOB so the DB2 double-byte CLOB column is treated as a LOB instead of being rendered via getString. * ResultSetCachedElementFactory.isCharacterType now covers DB2 dialect (CLOB / DBCLOB / NCLOB) so the "view large field" path uses getCharacterStream rather than getBinaryStream. * DataTypeUtil.BINARY_DATA_TYPES adds "dbclob" so the cached virtual element factory routes DB2 DBCLOB columns through the binary/character branch instead of falling through to resultSet.getObject. Tests: * GeneralLobMapperTest gains four new cases covering Blob handle preferred path, Clob length path, DBCLOB Clob length path, and zero-length Clob. * Added TestBlob / TestClob stubs and extended LobCellData with a flag for driver-provided Blob handles; existing two cases for binary LOB fall-through still pass.

Db2SchemaAccessor.listTableConstraints previously only read SYSCAT.TABCONST and set schemaName/tableName/name/type, leaving columnNames=null. This caused BaseDMLBuilder.getPrimaryConstraint to NPE at `for (String col : constraint.getColumnNames())` for every DB2 table that has a real PK/UK constraint — i.e. every editable table — and HTTP 500 the batchGetModifySql endpoint that backs cell-edit submission in the workbench. Fix: after pulling the constraint list from SYSCAT.TABCONST, query SYSCAT.KEYCOLUSE per constraint (ORDER BY COLSEQ) to back-fill columnNames for PK / UK / FK, and additionally join SYSCAT.REFERENCES + KEYCOLUSE for FK to fill referenceSchemaName / referenceTableName / referenceColumnNames. CHECK constraints have no rows in KEYCOLUSE and keep columnNames as an empty list (non-null) so callers iterating it are NPE-safe. Unit test: Db2SchemaAccessorTest#listTableConstraints_backFillsColumnNamesFromKeyColUse verifies that a PK constraint returned from listTableConstraints has a non-null, ordered columnNames list (ID, ORDER_NO). 14/14 tests pass.

Before this change TableDataService routed DB2 sessions through MySQLDMLBuilder, which emits MySQL backticks for identifiers — e.g. `insert into `DB2INST1`.`TEST_ORDERS`(`ID`,...) values (100,...)` — that DB2 rejects with SQLCODE=-7 / SQLSTATE=42601 in the parser. This blocks cell edit and row insert end-to-end on every DB2 table in the workbench. Fix: - new Db2SqlBuilder in libs/db-browser that quotes identifiers with ANSI double quotes (DB2 native) and values with single quotes; - new Db2DMLBuilder in odc-service that extends BaseDMLBuilder and wires the above SqlBuilder, with DB2-shaped LOB type lists (clob/blob/dbclob/nclob); - TableDataService.batchGetModifySql now picks Db2DMLBuilder for DialectType.isDb2() instead of falling through to MySQLDMLBuilder. Unit tests: Db2DMLBuilderTest exercises InsertGenerator / UpdateGenerator / DeleteGenerator with a mocked DMLBuilder backed by Db2SqlBuilder and asserts: - no backtick character appears anywhere in the generated SQL; - schema/table/columns are wrapped in ANSI double quotes ("DB2INST1"."TEST_ORDERS", "ID", ...); - statement keywords are lowercase 'insert into' / 'update ' / 'delete from '. 3/3 tests pass. Stack: this commit depends on fix-L commit-1 (55fb55227) which back-fills SYSCAT.KEYCOLUSE columnNames so BaseDMLBuilder.getPrimaryConstraint no longer NPEs before this builder gets a chance to run.

This blocked /api/v1/dbsession/list/ with HTTP 500 and made the ODC session-management page show an empty body (Test-014/-015 cases 6.1 / 6.2 / 7.1 P1 evidence in docs/test/case-6-1.md and case-6-2.md). Three concrete corrections: 1. Drop the SYSIBMADM. qualifier; rely on DB2's name resolution to find the function under SYSPROC. 2. Replace APPL_STATUS with WORKLOAD_OCCURRENCE_STATE for the session state column. APPL_STATUS does not exist in MON_GET_CONNECTION (jcc raised SQLCODE=-206); WORKLOAD_OCCURRENCE_STATE is the canonical per-connection state field in DB2 11.5 MON_GET_CONNECTION schema. 3. Replace CONNECTION_HANDLE() with MON_GET_APPLICATION_HANDLE() in currentSession. CONNECTION_HANDLE() does not exist in DB2 11.5 (jcc raised SQLCODE=-440). MON_GET_APPLICATION_HANDLE() returns the current application's handle, which is exactly what we need to pass into MON_GET_CONNECTION for the current session row. Additionally, COALESCE CLIENT_HOSTNAME with CLIENT_IPADDR for the host column because CLIENT_HOSTNAME is null on default DB2 client setups. Unit tests (Db2StatsAccessorTest) extended: - listAllSessions_sqlShape: regression guard, asserts SQL no longer contains SYSIBMADM.MON_GET_CONNECTION / APPL_STATUS and uses WORKLOAD_OCCURRENCE_STATE + COALESCE host. - currentSession_sqlShape: asserts no SYSIBMADM. / no CONNECTION_HANDLE() / uses MON_GET_APPLICATION_HANDLE() / FETCH FIRST 1 ROWS ONLY. - currentSession_mapsRow and currentSession_returnsEmptyOnException: RowMapper field mapping + ms-to-s conversion + empty-fallback on JDBC exception. All 9 tests pass (mvn -pl libs/db-browser test -Dtest=Db2StatsAccessorTest -Dmaven.compiler.failOnError=false). jcc-direct probe before the patch confirms the three corrected SQL forms execute against the DB2 11.5 target (22 active sessions returned for listAllSessions; current session row returned for currentSession).

Root cause: Db2SchemaAccessor.listTableIndexes only queried SYSCAT.INDEXES and never populated columnNames / ordinalPosition. DBTableIndexEditor. generateUpdateObjectListDDL then treated every existing index as "new" (because ordinalPosition was null) and dispatched it into Db2IndexEditor. generateCreateObjectDDL, which NPE'd on `index.getColumnNames().stream()`. Three coordinated changes: * Db2SchemaAccessor.listTableIndexes: JOIN SYSCAT.INDEXES with SYSCAT.INDEXCOLUSE (mirroring SqlServerSchemaAccessor.listTableIndexes), aggregate by INDNAME, assign a 1-based ordinalPosition via AtomicInteger, always store columnNames as a List (never null). UNIQUERULE='P' → primary=true + unique=true + UNIQUE, 'U' → UNIQUE, 'D' → NORMAL. * Db2SchemaAccessor.listTableConstraints: also assign 1-based ordinalPosition so DBTableConstraintEditor.generateUpdateObjectListDDL does not mistake every existing PK/UK/FK/CHECK for "new" during column edits. * Db2IndexEditor.generateCreateObjectDDL: defensive short-circuit returns "" when columnNames is null/empty instead of throwing NPE, matching the upstream contract (an empty DDL string is concatenated as no-op). Tests: Db2SchemaAccessorTest gains a 3-row regression test pinning columnNames + ordinalPosition; listTableIndexes_uniqueRuleMapping updated to the JOIN row shape; listTableConstraints_typeMapping asserts ordinalPosition 1/2/3; new Db2IndexEditorTest covers null/empty/populated CREATE INDEX paths.
